                           Examples:The kinds of acts that are common in health care are
               (1) a clinical observation, (2) an assessment of health condition (such as problems and
               diagnoses), (3) healthcare goals, (4) treatment services (such as medication, surgery,
               physical and psychological therapy), (5) assisting, monitoring or attending, (6) training
               and education services to patients and their next of kin, (7) and notary services (such
               as advanced directives or living will), (8)  editing and maintaining documents, and many
               others.

                           Discussion and Rationale: Acts are the pivot of the RIM; all
               domain information and processes are represented primarily in Acts. Any profession or
               business, including healthcare, is primarily constituted of intentional and occasionally
               non-intentional actions, performed and recorded by responsible actors. An Act-instance
               is a record of such an action.
            <br/>  

                        Acts connect to Entities in their Roles through Participations
               and connect to other Acts through ActRelationships. Participations are the authors, performers
               and other responsible parties as well as subjects and beneficiaries (which includes tools
               and material used in the performance of the act, which are also subjects). The moodCode
               distinguishes between Acts that are meant as factual records, vs. records of intended
               or ordered services, and the other modalities in which act can appear.
            <br/>  

                        One of the Participations that all acts have (at least implicitly)
               is a primary author, who is responsible of the Act and who &quot;owns&quot; the act. Responsibility
               for the act means responsibility for what is being stated in the Act and as what it is
               stated. Ownership of the act is assumed in the sense of who may operationally modify the
               same act. Ownership and responsibility of the Act is not the same as ownership or responsibility
               of what the Act-object refers to in the real world. The same real world activity can be
               described by two people, each being the author of their Act, describing the same real
               world activity. Yet one can be a witness while the other can be a principal performer.
               The performer has responsibilities for the physical actions; the witness only has responsibility
               for making a true statement to the best of his or her ability. The two Act-instances may
               even disagree, but because each is properly attributed to its author, such disagreements
               can exist side by side and left to arbitration by a recipient of these Act-instances.
            <br/>  

                        In this sense, an Act-instance represents a &quot;statement&quot;
               according to Rector and Nowlan (1991) [Foundations for an electronic medical record. Methods
               Inf Med. 30.]  Rector and Nowlan have emphasized the importance of understanding the medical
               record not as a collection of facts, but &quot;a faithful record of what clinicians have
               heard, seen, thought, and done.&quot; Rector and Nowlan go on saying that &quot;the other
               requirements for a medical record, e.g., that it be attributable and permanent, follow
               naturally from this view.&quot; Indeed the Act class is this attributable statement, and
               the rules of updating acts (discussed in the state-transition model, see Act.statusCode)
               versus generating new Act-instances are designed according to this principle of permanent
               attributable statements.
            <br/>  

                        Rector and Nolan focus on the electronic medical record as a collection
               of statements, while attributed statements, these are still mostly factual statements.
               However, the Act class goes beyond this limitation to attributed factual statements, representing
               what is known as &quot;speech-acts&quot; in linguistics and philosophy.  The notion of
               speech-act includes that there is pragmatic meaning in language utterances, aside from
               just factual statements; and that these utterances interact with the real world to change
               the state of affairs, even directly cause physical activities to happen. For example,
               an order is a speech act that (provided it is issued adequately) will cause the ordered
               action to be physically performed. The speech act theory has culminated in the seminal
               work by Austin (1962) [How to do things with words. Oxford University Press].
            <br/>  

                        An activity in the real world may progress from defined, through
               planned and ordered to executed, which is represented as the mood of the Act. Even though
               one might think of a single activity as progressing from planned to executed, this progression
               is reflected by multiple Act-instances, each having one and only one mood that will not
               change along the Act-instance life cycle.  This is because the attribution and content
               of speech acts along this progression of an activity may be different, and it is often
               critical that a permanent and faithful record be maintained of this progression. The specification
               of orders or promises or plans must not be overwritten by the specification of what was
               actually done, so as to allow comparing actions with their earlier specifications. Act-instances
               that describe this progression of the same real world activity are linked through the
               ActRelationships (of the relationship category &quot;sequel&quot;).
            <br/>  

                        Act as statements or speech-acts are the only representation of
               real world facts or processes in the HL7 RIM. The truth about the real world is constructed
               through a combination (and arbitration) of such attributed statements only, and there
               is no class in the RIM whose objects represent &quot;objective state of affairs&quot;
               or &quot;real processes&quot; independent from attributed statements. As such, there is
               no distinction between an activity and its documentation. Every Act includes both to varying
               degrees. For example, a factual statement made about recent (but past) activities, authored
               (and signed) by the performer of such activities, is commonly known as a procedure report
               or original documentation (e.g., surgical procedure report, clinic note etc.). Conversely,
               a status update on an activity that is presently in progress, authored by the performer
               (or a close observer) is considered to capture that activity (and is later superceded
               by a full procedure report). However, both status update and procedure report are acts
               of the same kind, only distinguished by mood and state (see statusCode) and completeness
               of the information.

                        The notion of a document comes particularly from the paper world,
               where it corresponds to the contents recorded on discrete pieces of paper. In the electronic
               world, a document is a kind of composition that bears resemblance to their paper world
               counter-parts. Documents typically are meant to be human-readable.
            <br/>  

                        HL7's notion of document differs from that described in the W3C
               XML Recommendation, in which a document refers specifically to the contents that fall
               between the root element's start-tag and end-tag. Not all XML documents are HL7 documents.

               navigation. Clinical headings usually reflect the clinical workflow during a care session,
               and might also reflect the main author's reasoning processes. Much research has demonstrated
               that headings are used differently by different professional groups and specialties, and
               that headings are not used consistently enough to support safe automatic processing of
               the E H R.

                           UsageNotes: Typically a Public Health Case involves an instance
               or instances of a reportable infectious disease or other condition. The public health
               case can include a health-related event concerning a single individual or it may refer
               to multiple health-related events that are occurrences of the same disease or condition
               of interest to public health.
            <br/>  

                        A public health case definition (Act.moodCode = &quot;definition&quot;)
               includes the description of the clinical, laboratory, and epidemiologic indicators associated
               with a disease or condition of interest to public health. There are case definitions for
               conditions that are reportable, as well as for those that are not. A public health case
               definition is a construct used by public health for the purpose of counting cases, and
               should not be used as clinical indications for treatment. Examples include AIDS, toxic-shock
               syndrome, and salmonellosis and their associated indicators that are used to define a
               case.

                        An Outbreak is a concern resulting from a series of public health
               cases.
            <br/>  

                        
                           UsageNotes: The date on which an outbreak starts is the earliest
               date of onset among the cases assigned to the outbreak and its ending date is the last
               date of onset among the cases assigned to the outbreak. The effectiveTime attribute is
               used to convey the relevant dates for the case. An outbreak definition (Act.moodCode =
               &quot;definition&quot; includes the criteria for the number, types and occurrence pattern
               of cases necessary to declare an outbreak and to judge the severity of an outbreak.

                        The Consent class represents informed consents and all similar
               medico-legal transactions between the patient (or his legal guardian) and the provider.
               Examples are informed consent for surgical procedures, informed consent for clinical trials,
               advanced beneficiary notice, against medical advice decline from service, release of information
               agreement, etc.
            <br/>  

                        The details of consents vary. Often an institution has a number
               of different consent forms for various purposes, including reminding the physician about
               the topics to mention. Such forms also include patient education material. In electronic
               medical record communication, consents thus are information-generating acts on their own
               and need to be managed similar to medical activities. Thus, Consent is modeled as a special
               class of Act.
            <br/>  

                        The &quot;signatures&quot; to the consent document are represented
               electronically through Participation instances to the consent object. Typically an informed
               consent has Participation.typeCode of &quot;performer&quot;, the healthcare provider informing
               the patient, and &quot;consenter&quot;, the patient or legal guardian. Some consent may
               associate a witness or a notary public (e.g., living wills, advanced directives). In consents
               where a healthcare provider is not required (e.g. living will), the performer may be the
               patient himself or a notary public.
            <br/>  

                        Some consent has a minimum required delay between the consent
               and the service, so as to allow the patient to rethink his decisions. This minimum delay
               can be expressed in the act definition by the ActRelationship.pauseQuantity attribute
               that delays the service until the pause time has elapsed after the consent has been completed.

               exposure.

                              A patient accidentally is dispensed an incorrect medicine
               (e.g., clomiphene instead of clomipramine).  They have taken several doses before the
               mistake is detected.  They are therefore &quot;exposed&quot; to a medicine that there
               was no therapeutic indication for them to receive. 
            <br/>  

                              
                                 
                                    There are several substance administrations in this

                              In a busy medical ward, a patient is receiving chemotherapy
               for a lymphoma.  Unfortunately, the IV infusion bag containing the medicine splits, spraying
               cytotoxic medication over the patient being treated and the patient in the adjacent bed.

                                    There are three substance administrations in this
               example.  The first is the intended one (IV infusion) with its associated (implicit) exposure.
                There is an incident with an associated substance administration to the same patient
               involving the medication sprayed over the patient as well as an associated exposure. 
               Additionally, the incident includes a substance administration involving the spraying
               of medication on the adjacent patient, also with an associated exposure.

               arrives in a busy inner city A&amp;E department suffering from a cough with bloody sputum.
                Not understanding the registration and triage process, they sit in the waiting room for
               several hours before it is noticed that they have not booked in.  As soon as they are
               being processed, it is suspected that they are suffering from TB.  Vulnerable (immunosuppressed)
               patients who were sharing the waiting room with this patient may have been exposed to
               the tubercule bacillus, and must be traced for investigation.

                                    This is an exposure (or possibly multiple exposures)
               in the waiting room involving the refugee and everyone else in the waiting room during
               the period.  There might also be a number of known or presumed substance administrations
               (coughing) via several possible routes.  The substance administrations are only hypotheses
               until confirmed by further testing.

                              A patient who has received an elective total hip replacement
               procedure suffers a prolonged stay in hospital, due to contracting an MRSA infection in
               the surgical wound site after the surgery.

                                    This is an exposure to MRSA.  Although there was some
               sort of substance administration, it's possible the exact mechanism for introduction of
               the MRSA into the wound will not be identified.

                              Routine maintenance of the X-ray machines at a local hospital
               reveals a serious breach of the shielding on one of the machines.  Patients who have undergone
               investigations using that machine in the last month are likely to have been exposed to
               significantly higher doses of X-rays than was intended, and must be tracked for possible
               adverse effects.

                                    There has been an exposure of each patient who used
               the machine in the past 30 days. Some patients may have had substance administrations.

                              A new member of staff is employed in the laundry processing
               room of a small cottage hospital, and a misreading of the instructions for adding detergents
               results in fifty times the usual concentration of cleaning materials being added to a
               batch of hospital bedding.  As a result, several patients have been exposed to very high
               levels of detergents still present in the &quot;clean&quot; bedding, and have experienced
               dermatological reactions to this.

                                    There has been an incident with multiple exposures
               to several patients.  Although there are substance administrations involving the application
               of the detergent to the skin of the patients, it is expected that the substance administrations
               would not be directly documented.

                              Seven patients who are residents in a health care facility
               for the elderly mentally ill have developed respiratory problems. After several months
               of various tests having been performed and various medications prescribed to these patients,
               the problem is traced to their being &quot;sensitive&quot; to a new fungicide used in
               the wall plaster of the ward where these patients reside.

                                    The patients have been continuously exposed to the
               fungicide.  Although there have been continuous substance administrations (via breathing)
               this would not normally be documented as a substance administration.

                              A patient with osteoarthritis of the knees is treated symptomatically
               using analgesia, paracetamol (acetaminophen) 1g up to four times a day for pain relief.
                His GP does not realize that the patient has, 20 years previously (while at college)
               had severe alcohol addiction problems, and now, although this is completely under control,
               his liver has suffered significantly, leaving him more sensitive to hepatic toxicity from
               paracetamol use.  Later that year, the patient returns with a noticeable level of jaundice.
                Paracetamol is immediately withdrawn and alternative solutions for the knee pain are
               sought.  The jaundice gradually subsides with conservative management, but referral to
               the gastroenterologist is required for advice and monitoring.

                                    There is a substance administration with an associated
               exposure.  The exposure component is based on the relative toxic level of the substance
               to a patient with a compromised liver function.

                              A patient goes to their GP complaining of abdominal pain,
               having been discharged from the local hospital ten days' previously after an emergency
               appendectomy.  The GP can find nothing particularly amiss, and presumes it is post operative
               surgical pain that will resolve.  The patient returns a fortnight later, when the GP prescribes
               further analgesia, but does decide to request an outpatient surgical follow-up appointment.
                At this post-surgical outpatient review, the registrar decides to order an ultrasound,
               which, when performed three weeks later, shows a small faint inexplicable mass.  A laparoscopy
               is then performed, as a day case procedure, and a piece of a surgical swab is removed
               from the patient's abdominal cavity.  Thankfully, a full recovery then takes place.

               recorded for this also.

                              A patient is slightly late for a regular pacemaker battery
               check in the Cardiology department of the local hospital.  They are hurrying down the
               second floor corridor.  A sudden summer squall has recently passed over the area, and
               rain has come in through an open corridor window leaving a small puddle on the corridor
               floor.  In their haste, the patient slips in the puddle and falls so badly that they have

                        Exposure differs from Substance Administration by the absence
               of the participation of a performer in the act.

                        The following participations SHOULD be used with the following
               participations to distinguish the specific entities:
            <br/>  

                        
                           
                              The exposed entity participates via the &quot;exposure target&quot;
               (EXPTRGT) participation.
            <br/>  

                           
                           
                              An entity that has carried the agent transmitted in the
               exposure participates via the &quot;exposure source&quot; (EXSRC) participation.  For
               example: 
            <br/>  

                              
                                 
                                    a person or animal who carried an infectious disease
               and interacts (EXSRC) with another person or animal (EXPTRGT) transmitting the disease
               agent;
            <br/>  

                                 
                                 
                                    a place or other environment (EXSRC) and a person
               or animal (EXPTRGT) who is exposed in the presence of this environment.
            <br/>  

                                 
                              
                           
                           
                              When it is unknown whether a participating entity is the
               source of the agent (EXSRC) or the target of the transmission (EXPTRGT), the &quot;exposure
               participant&quot; (EXPART) is used.
            <br/>  

                           
                           
                              The physical (including energy), chemical or biological
               substance which is participating in the exposure uses the &quot;exposure agent&quot; (EXPAGNT)
               participation.  There are at least three scenarios:
            <br/>  

                              
                                 
                                    the player of the Role that participates as EXPAGNT
               is the chemical or biological substance mixed or carried by the scoper-entity of the Role
               (e.g., ingredient role); or 
            <br/>  

                                 
                                 
                                    the player of the Role that participates as EXPAGNT
               is a mixture known to contain the chemical, radiological or biological substance of interest;
               or 
            <br/>  

                                 
                                 
                                    the player of the Role that participates as a EXPAGNT
               is known to carry the agent (i.e., the player is a fomite, vector, etc.).
            <br/>  

                                 
                              
                           
                        
                        The Exposure.statusCode attribute should be interpreted as the
               state of the Exposure business object (e.g., active, aborted, completed) and not the clinical
               status of the exposure (e.g., probable, confirmed).  The clinical status of the exposure
               should be associated with the exposure via a subject observation.
            <br/>  

                        
                           Design Comment: The usage notes require a clear criterion for
               determining whether an act is an exposure or substance administration-deleterious potential,
               uncertainty of actual transmission, or otherwise. SBADM states that the criterion is the
               presence of a performer-but there are examples above that call this criterion into question
               (e.g., the first one, concerning a dosing error).

                        An acquisition exposure act describes the proximity (location
               and time) through which the participating entity was potentially exposed to a physical
               (including energy), chemical or biological agent from another entity.  The acquisition
               exposure act is used in conjunction with transmission exposure acts as part of an analysis
               technique for contact tracing.  Although an exposure can be decomposed into transmission
               and acquisition exposures, there is no requirement that all exposures be treated in this

                           Description:An act that is intended to result in new information
               about a subject. The main difference between Observations and other Acts is that Observations
               have a value attribute. The code attribute of Observation and the value attribute of Observation
               must be considered in combination to determine the semantics of the observation.
            <br/>  

                        
                           Discussion:
                        
            <br/>  

                        Structurally, many observations are name-value-pairs, where the
               Observation.code (inherited from Act) is the name and the Observation.value is the value
               of the property. Such a construct is also known as a  variable (a named feature that can
               assume a value) hence, the Observation class is always used to hold generic name-value-pairs
               or variables, even though the variable valuation may not be the result of an elaborate
               observation method. It may be a simple answer to a question or it may be an assertion
               or setting of a parameter.
            <br/>  

                        As with all Act statements, Observation statements describe what
               was done, and in the case of Observations, this includes a description of what was actually
               observed (results or answers); and those results or answers are part of the observation
               and not split off into other objects. 
            <br/>  

                        The method of action is asserted by the Observation classCode
               or its subclasses at the least granular level, by the Observation.code attribute value
               at the medium level of granularity, and by the attribute value of observation.methodCode
               when a finer level of granularity is required. The method in whole or in part may also
               appear in the attribute value of Observation.value when using coded data types to express
               the value of the attribute. Relevant aspects of methodology may also be restated in value
               when the results themselves imply or state a methodology.
            <br/>  

                        An observation may consist of component observations each having
               their own Observation.code and Observation.value. In this case, the composite observation
               may not have an Observation.value for itself. For instance, a white blood cell count consists
               of the sub-observations for the counts of the various granulocytes, lymphocytes and other
               normal or abnormal blood cells (e.g., blasts). The overall white blood cell count Observation
               itself may therefore not have a value by itself (even though it could have one, e.g.,
               the sum total of white blood cells). Thus, as long as an Act is essentially an Act of
               recognizing and noting information about a subject, it is an Observation, regardless of
               whether it has a simple value by itself or whether it has sub-observations.
            <br/>  

                        Even though observations are professional acts (see Act) and as
               such are intentional actions, this does not require that every possible outcome of an
               observation be pondered in advance of it being actually made. For instance, differential
               white blood cell counts (WBC) rarely show blasts, but if they do, this is part of the
               WBC observation even though blasts might not be predefined in the structure of a normal
               WBC. 
            <br/>  

                        Clinical documents commonly have Subjective and Objective findings,
               both of which are kinds of Observations. In addition, clinical documents commonly contain
               Assessments, which are also kinds of Observations. Thus, the establishment of a diagnosis
               is an Observation.

                        A Region of Interest (ROI) specified for a multidimensional observation,
               such as an Observation Series (OBSSER). The ROI is specified using a set of observation
               criteria, each delineating the boundary of the region in one of the dimensions in the
               multidimensional observation. The relationship between a ROI and its referenced Act is
               specified through an ActRelationship of type subject (SUBJ), which must always be present.
               Each of the boundary criteria observations is connected with the ROI using ActRelationships
               of type &quot;has component&quot; (COMP). In each boundary criterion, the Act.code names
               the dimension and the Observation.value specifies the range of values inside the region.
               Typically the bounded dimension is continuous, and so the Observation.value will be an
               interval (IVL) data type. The Observation.value need not be specified if the respective
               dimension is only named but not constrained. For example, an ROI for the QT interval of
               a certain beat in ECG Lead II would contain 2 boundary criteria, one naming the interval
               in time (constrained), and the other naming the interval in ECG Lead II (only named, but
               not constrained).

                        A Region of Interest (ROI) specified for an image using an overlay
               shape. Typically used to make reference to specific regions in images, e.g., to specify
               the location of a radiologic finding in an image or to specify the site of a physical
               finding by &quot;circling&quot; a region in a schematic picture of a human body. The units
               of the coordinate values are in pixels.  The origin is in the upper left hand corner,
               with positive X values going to the right and positive Y values going down. The relationship
               between a ROI and its referenced Act is specified through an ActRelationship of type &quot;subject&q
              uot; (SUBJ), which must always be present.

                        An observation identifying a potential adverse outcome as a result

            <br/>  

                        
                           Examples: Detection of a drug-drug interaction; Identification
               of a late-submission for an invoice; Requesting discharge for a patient who does not meet
               hospital-defined discharge criteria.

                           Discussion: This class is commonly used for identifying 'business
               rule' or 'process' problems that may result in a refusal to carry out a particular request.
               In some circumstances it may be possible to 'bypass' a problem by modifying the request
               to acknowledge the issue and/or by providing some form of mitigation.
            <br/>  

                        
                           Constraints: the Act or Acts that may cause the the adverse
               outcome are the target of a subject ActRelationship. The subbtypes of this concept indicate
               the type of problem being detected (e.g. drug-drug interaction) while the Observation.value
               is used to repesent a specific problem code (e.g. specific drug-drug interaction id).

                           Definition: An observation that is composed of a set of observations.
               These observations typically have a logical or practical grouping for generally accepted
               clinical or functional purposes, such as observations that are run together because of
               automation. A battery can define required and optional component observations and, in
               some cases, will define complex rules that determine whether or not a particular observation
               is made. BATTERY is a constraint on the Observation class in that it is understood to
               always be composed of component observations.
            <br/>  

                        
                           UsageNotes: The focus in a BATTERY is that it is composed of
               individual observations. In request (RQO) mood, a battery is a request to perform the
               component observations. In event (EVN) mood a battery is a reporting of associated set
               of observation events. In definition mood a battery is the definition of the associated
               set of observations.

                        A public health case is an Observation representing a condition
               or event that has a specific significance for public health. Typically it involves an
               instance or instances of a reportable infectious disease or other condition. The public
               health case can include a health-related event concerning a single individual or it may
               refer to multiple health-related events that are occurrences of the same disease or condition
               of interest to public health. An outbreak involving multiple individuals may be considered
               as a type of public health case. A public health case definition (Act.moodCode = &quot;definition&qu
              ot;) includes the description of the clinical, laboratory, and epidemiologic indicators
               associated with a disease or condition of interest to public health. There are case definitions
               for conditions that are reportable, as well as for those that are not. There are also
               case definitions for outbreaks. A public health case definition is a construct used by
               public health for the purpose of counting cases, and should not be used as clinical indications
               for treatment. Examples include AIDS, toxic-shock syndrome, and salmonellosis and their
               associated indicators that are used to define a case.

                        Supply orders and deliveries are simple Acts that focus on the
               delivered product. The product is associated with the Supply Act via Participation.typeCode=&quot;pr
              oduct&quot;. With general Supply Acts, the precise identification of the Material (manufacturer,
               serial numbers, etc.) is important.  Most of the detailed information about the Supply
               should be represented using the Material class.  If delivery needs to be scheduled, tracked,
               and billed separately, one can associate a Transportation Act with the Supply Act.  Pharmacy
               dispense services are represented as Supply Acts, associated with a SubstanceAdministration
                Act. The SubstanceAdministration class represents the administration of medication, while
               dispensing is supply.

                        The record entries relating to a single clinical session are usually
               grouped under headings that represent phases of the encounter, or assist with layout and
               navigation. Clinical headings usually reflect the clinical workflow during a care session,
               and might also reflect the main author's reasoning processes. Much research has demonstrated
               that headings are used differently by different professional groups and specialties, and
               that headings are not used consistently enough to support safe automatic processing of
               the E H R.

                           Examples:The kinds of acts that are common in health care are
       (1) a clinical observation, (2) an assessment of health condition (such as problems and
       diagnoses), (3) healthcare goals, (4) treatment services (such as medication, surgery,
       physical and psychological therapy), (5) assisting, monitoring or attending, (6) training
       and education services to patients and their next of kin, (7) and notary services (such
       as advanced directives or living will), (8)  editing and maintaining documents, and many
       others.

                        
                           Discussion and Rationale: Acts are the pivot of the RIM; all
       domain information and processes are represented primarily in Acts. Any profession or
       business, including healthcare, is primarily constituted of intentional and occasionally
       non-intentional actions, performed and recorded by responsible actors. An Act-instance
       is a record of such an action.

                        Acts connect to Entities in their Roles through Participations
       and connect to other Acts through ActRelationships. Participations are the authors, performers
       and other responsible parties as well as subjects and beneficiaries (which includes tools
       and material used in the performance of the act, which are also subjects). The moodCode
       distinguishes between Acts that are meant as factual records, vs. records of intended
       or ordered services, and the other modalities in which act can appear.

                        One of the Participations that all acts have (at least implicitly)
       is a primary author, who is responsible of the Act and who &quot;owns&quot; the act. Responsibility
       for the act means responsibility for what is being stated in the Act and as what it is
       stated. Ownership of the act is assumed in the sense of who may operationally modify the
       same act. Ownership and responsibility of the Act is not the same as ownership or responsibility
       of what the Act-object refers to in the real world. The same real world activity can be
       described by two people, each being the author of their Act, describing the same real
       world activity. Yet one can be a witness while the other can be a principal performer.
       The performer has responsibilities for the physical actions; the witness only has responsibility
       for making a true statement to the best of his or her ability. The two Act-instances may
       even disagree, but because each is properly attributed to its author, such disagreements
       can exist side by side and left to arbitration by a recipient of these Act-instances.

                        In this sense, an Act-instance represents a &quot;statement&quot;
       according to Rector and Nowlan (1991) [Foundations for an electronic medical record. Methods
       Inf Med. 30.]  Rector and Nowlan have emphasized the importance of understanding the medical
       record not as a collection of facts, but &quot;a faithful record of what clinicians have
       heard, seen, thought, and done.&quot; Rector and Nowlan go on saying that &quot;the other
       requirements for a medical record, e.g., that it be attributable and permanent, follow
       naturally from this view.&quot; Indeed the Act class is this attributable statement, and
       the rules of updating acts (discussed in the state-transition model, see Act.statusCode)
       versus generating new Act-instances are designed according to this principle of permanent
       attributable statements.

                        Rector and Nolan focus on the electronic medical record as a collection
       of statements, while attributed statements, these are still mostly factual statements.
       However, the Act class goes beyond this limitation to attributed factual statements, representing
       what is known as &quot;speech-acts&quot; in linguistics and philosophy.  The notion of
       speech-act includes that there is pragmatic meaning in language utterances, aside from
       just factual statements; and that these utterances interact with the real world to change
       the state of affairs, even directly cause physical activities to happen. For example,
       an order is a speech act that (provided it is issued adequately) will cause the ordered
       action to be physically performed. The speech act theory has culminated in the seminal
       work by Austin (1962) [How to do things with words. Oxford University Press].

                        An activity in the real world may progress from defined, through
       planned and ordered to executed, which is represented as the mood of the Act. Even though
       one might think of a single activity as progressing from planned to executed, this progression
       is reflected by multiple Act-instances, each having one and only one mood that will not
       change along the Act-instance life cycle.  This is because the attribution and content
       of speech acts along this progression of an activity may be different, and it is often
       critical that a permanent and faithful record be maintained of this progression. The specification
       of orders or promises or plans must not be overwritten by the specification of what was
       actually done, so as to allow comparing actions with their earlier specifications. Act-instances
       that describe this progression of the same real world activity are linked through the
       ActRelationships (of the relationship category &quot;sequel&quot;).

                        Act as statements or speech-acts are the only representation of
       real world facts or processes in the HL7 RIM. The truth about the real world is constructed
       through a combination (and arbitration) of such attributed statements only, and there
       is no class in the RIM whose objects represent &quot;objective state of affairs&quot;
       or &quot;real processes&quot; independent from attributed statements. As such, there is
       no distinction between an activity and its documentation. Every Act includes both to varying
       degrees. For example, a factual statement made about recent (but past) activities, authored
       (and signed) by the performer of such activities, is commonly known as a procedure report
       or original documentation (e.g., surgical procedure report, clinic note etc.). Conversely,
       a status update on an activity that is presently in progress, authored by the performer
       (or a close observer) is considered to capture that activity (and is later superceded
       by a full procedure report). However, both status update and procedure report are acts
       of the same kind, only distinguished by mood and state (see statusCode) and completeness
       of the information."/>

        <definition value="A public health case is a Concern about an observation or event that has a specific significance
           for public health. The creation of a PublicHealthCase initiates the tracking of the object
           of concern.  The decision to track is related to but somewhat independent of the underlying
           event or observation.

                        
                           UsageNotes: Typically a Public Health Case involves an instance
           or instances of a reportable infectious disease or other condition. The public health
           case can include a health-related event concerning a single individual or it may refer
           to multiple health-related events that are occurrences of the same disease or condition
           of interest to public health.

                        A public health case definition (Act.moodCode = &quot;definition&quot;)
           includes the description of the clinical, laboratory, and epidemiologic indicators associated
           with a disease or condition of interest to public health. There are case definitions for
           conditions that are reportable, as well as for those that are not. A public health case
           definition is a construct used by public health for the purpose of counting cases, and
           should not be used as clinical indications for treatment. Examples include AIDS, toxic-shock

         against medical advice decline from service, release of information agreement, etc.

                        The details of consents vary. Often an institution has a number
         of different consent forms for various purposes, including reminding the physician about
         the topics to mention. Such forms also include patient education material. In electronic
         medical record communication, consents thus are information-generating acts on their own
         and need to be managed similar to medical activities. Thus, Consent is modeled as a special
         class of Act.

                        The &quot;signatures&quot; to the consent document are represented
         electronically through Participation instances to the consent object. Typically an informed
         consent has Participation.typeCode of &quot;performer&quot;, the healthcare provider informing
         the patient, and &quot;consenter&quot;, the patient or legal guardian. Some consent may
         associate a witness or a notary public (e.g., living wills, advanced directives). In consents
         where a healthcare provider is not required (e.g. living will), the performer may be the
         patient himself or a notary public.

                        Some consent has a minimum required delay between the consent
         and the service, so as to allow the patient to rethink his decisions. This minimum delay

                              A patient accidentally receives three times the recommended

                                    This is a substance administration.  Public health
         and/or safety authorities may also be interested in documenting this with an associated
         exposure.

                                 
                              
                           
                           
                              A patient accidentally is dispensed an incorrect medicine
         (e.g., clomiphene instead of clomipramine).  They have taken several doses before the
         mistake is detected.  They are therefore &quot;exposed&quot; to a medicine that there
         was no therapeutic indication for them to receive. 

                              
                                 
                                    There are several substance administrations in this
         example.  Public health and/or safety authorities may also be interested in documenting
         this with associated exposures.

                                 
                              
                           
                           
                              In a busy medical ward, a patient is receiving chemotherapy
         for a lymphoma.  Unfortunately, the IV infusion bag containing the medicine splits, spraying
         cytotoxic medication over the patient being treated and the patient in the adjacent bed.
         

                              
                                 
                                    There are three substance administrations in this
         example.  The first is the intended one (IV infusion) with its associated (implicit) exposure.
          There is an incident with an associated substance administration to the same patient
         involving the medication sprayed over the patient as well as an associated exposure. 
         Additionally, the incident includes a substance administration involving the spraying
         of medication on the adjacent patient, also with an associated exposure.

                                 
                              
                           
                           
                              A patient who is a refugee from a war-torn African nation
         arrives in a busy inner city A&amp;E department suffering from a cough with bloody sputum.
          Not understanding the registration and triage process, they sit in the waiting room for
         several hours before it is noticed that they have not booked in.  As soon as they are
         being processed, it is suspected that they are suffering from TB.  Vulnerable (immunosuppressed)
         patients who were sharing the waiting room with this patient may have been exposed to
         the tubercule bacillus, and must be traced for investigation. 

                              
                                 
                                    This is an exposure (or possibly multiple exposures)
         in the waiting room involving the refugee and everyone else in the waiting room during
         the period.  There might also be a number of known or presumed substance administrations
         (coughing) via several possible routes.  The substance administrations are only hypotheses
         until confirmed by further testing.

                                 
                              
                           
                           
                              A patient who has received an elective total hip replacement
         procedure suffers a prolonged stay in hospital, due to contracting an MRSA infection in
         the surgical wound site after the surgery. 

                              
                                 
                                    This is an exposure to MRSA.  Although there was some
         sort of substance administration, it's possible the exact mechanism for introduction of
         the MRSA into the wound will not be identified.

                                 
                              
                           
                           
                              Routine maintenance of the X-ray machines at a local hospital
         reveals a serious breach of the shielding on one of the machines.  Patients who have undergone
         investigations using that machine in the last month are likely to have been exposed to
         significantly higher doses of X-rays than was intended, and must be tracked for possible
         adverse effects. 

                              
                                 
                                    There has been an exposure of each patient who used
         the machine in the past 30 days. Some patients may have had substance administrations.

                                 
                              
                           
                           
                              A new member of staff is employed in the laundry processing
         room of a small cottage hospital, and a misreading of the instructions for adding detergents
         results in fifty times the usual concentration of cleaning materials being added to a
         batch of hospital bedding.  As a result, several patients have been exposed to very high
         levels of detergents still present in the &quot;clean&quot; bedding, and have experienced
         dermatological reactions to this. 

                              
                                 
                                    There has been an incident with multiple exposures
         to several patients.  Although there are substance administrations involving the application
         of the detergent to the skin of the patients, it is expected that the substance administrations
         would not be directly documented.

                                 
                              
                           
                           
                              Seven patients who are residents in a health care facility
         for the elderly mentally ill have developed respiratory problems. After several months
         of various tests having been performed and various medications prescribed to these patients,
         the problem is traced to their being &quot;sensitive&quot; to a new fungicide used in
         the wall plaster of the ward where these patients reside.

                              
                                 
                                    The patients have been continuously exposed to the
         fungicide.  Although there have been continuous substance administrations (via breathing)
         this would not normally be documented as a substance administration.

                                 
                              
                           
                           
                              A patient with osteoarthritis of the knees is treated symptomatically
         using analgesia, paracetamol (acetaminophen) 1g up to four times a day for pain relief.
          His GP does not realize that the patient has, 20 years previously (while at college)
         had severe alcohol addiction problems, and now, although this is completely under control,
         his liver has suffered significantly, leaving him more sensitive to hepatic toxicity from
         paracetamol use.  Later that year, the patient returns with a noticeable level of jaundice.
          Paracetamol is immediately withdrawn and alternative solutions for the knee pain are
         sought.  The jaundice gradually subsides with conservative management, but referral to
         the gastroenterologist is required for advice and monitoring. 

                              
                                 
                                    There is a substance administration with an associated
         exposure.  The exposure component is based on the relative toxic level of the substance
         to a patient with a compromised liver function.

                                 
                              
                           
                           
                              A patient goes to their GP complaining of abdominal pain,
         having been discharged from the local hospital ten days' previously after an emergency
         appendectomy.  The GP can find nothing particularly amiss, and presumes it is post operative
         surgical pain that will resolve.  The patient returns a fortnight later, when the GP prescribes
         further analgesia, but does decide to request an outpatient surgical follow-up appointment.
          At this post-surgical outpatient review, the registrar decides to order an ultrasound,
         which, when performed three weeks later, shows a small faint inexplicable mass.  A laparoscopy
         is then performed, as a day case procedure, and a piece of a surgical swab is removed
         from the patient's abdominal cavity.  Thankfully, a full recovery then takes place. 

                              
                                 
                                    This is a procedural sequelae.  There may be an Incident
         recorded for this also.

                                 
                              
                           
                           
                              A patient is slightly late for a regular pacemaker battery
         check in the Cardiology department of the local hospital.  They are hurrying down the
         second floor corridor.  A sudden summer squall has recently passed over the area, and
         rain has come in through an open corridor window leaving a small puddle on the corridor
         floor.  In their haste, the patient slips in the puddle and falls so badly that they have
         to be taken to the A&amp;E department, where it is discovered on investigation they have
         slightly torn the cruciate ligament in their left knee. 

                              
                                 
                                    This is not an exposure.  There has been an incident.

         (EXPTRGT) participation.

                           
                           
                              An entity that has carried the agent transmitted in the
         exposure participates via the &quot;exposure source&quot; (EXSRC) participation.  For
         example: 

                              
                                 
                                    a person or animal who carried an infectious disease
         and interacts (EXSRC) with another person or animal (EXPTRGT) transmitting the disease
         agent;

                                 
                                 
                                    a place or other environment (EXSRC) and a person
         or animal (EXPTRGT) who is exposed in the presence of this environment.

                                 
                              
                           
                           
                              When it is unknown whether a participating entity is the
         source of the agent (EXSRC) or the target of the transmission (EXPTRGT), the &quot;exposure
         participant&quot; (EXPART) is used.

                           
                           
                              The physical (including energy), chemical or biological
         substance which is participating in the exposure uses the &quot;exposure agent&quot; (EXPAGNT)
         participation.  There are at least three scenarios:

                              
                                 
                                    the player of the Role that participates as EXPAGNT
         is the chemical or biological substance mixed or carried by the scoper-entity of the Role
         (e.g., ingredient role); or 

                                 
                                 
                                    the player of the Role that participates as EXPAGNT
         is a mixture known to contain the chemical, radiological or biological substance of interest;
         or 

                                 
                                 
                                    the player of the Role that participates as a EXPAGNT
         is known to carry the agent (i.e., the player is a fomite, vector, etc.).

                                 
                              
                           
                        
                        The Exposure.statusCode attribute should be interpreted as the
         state of the Exposure business object (e.g., active, aborted, completed) and not the clinical
         status of the exposure (e.g., probable, confirmed).  The clinical status of the exposure
         should be associated with the exposure via a subject observation.

                        
                           Design Comment: The usage notes require a clear criterion for
         determining whether an act is an exposure or substance administration-deleterious potential,
         uncertainty of actual transmission, or otherwise. SBADM states that the criterion is the
         presence of a performer-but there are examples above that call this criterion into question
         (e.g., the first one, concerning a dosing error)."/>

      <definition value="Description:An act that is intended to result in new information about a subject. The
         main difference between Observations and other Acts is that Observations have a value
         attribute. The code attribute of Observation and the value attribute of Observation must
         be considered in combination to determine the semantics of the observation.

                        
                           Discussion:
                        

                        Structurally, many observations are name-value-pairs, where the
         Observation.code (inherited from Act) is the name and the Observation.value is the value
         of the property. Such a construct is also known as a  variable (a named feature that can
         assume a value) hence, the Observation class is always used to hold generic name-value-pairs
         or variables, even though the variable valuation may not be the result of an elaborate
         observation method. It may be a simple answer to a question or it may be an assertion
         or setting of a parameter.

                        As with all Act statements, Observation statements describe what
         was done, and in the case of Observations, this includes a description of what was actually
         observed (results or answers); and those results or answers are part of the observation
         and not split off into other objects. 

                        The method of action is asserted by the Observation classCode
         or its subclasses at the least granular level, by the Observation.code attribute value
         at the medium level of granularity, and by the attribute value of observation.methodCode
         when a finer level of granularity is required. The method in whole or in part may also
         appear in the attribute value of Observation.value when using coded data types to express
         the value of the attribute. Relevant aspects of methodology may also be restated in value
         when the results themselves imply or state a methodology.

                        An observation may consist of component observations each having
         their own Observation.code and Observation.value. In this case, the composite observation
         may not have an Observation.value for itself. For instance, a white blood cell count consists
         of the sub-observations for the counts of the various granulocytes, lymphocytes and other
         normal or abnormal blood cells (e.g., blasts). The overall white blood cell count Observation
         itself may therefore not have a value by itself (even though it could have one, e.g.,
         the sum total of white blood cells). Thus, as long as an Act is essentially an Act of
         recognizing and noting information about a subject, it is an Observation, regardless of
         whether it has a simple value by itself or whether it has sub-observations.

                        Even though observations are professional acts (see Act) and as
         such are intentional actions, this does not require that every possible outcome of an
         observation be pondered in advance of it being actually made. For instance, differential
         white blood cell counts (WBC) rarely show blasts, but if they do, this is part of the
         WBC observation even though blasts might not be predefined in the structure of a normal
         WBC. 

                        Clinical documents commonly have Subjective and Objective findings,
         both of which are kinds of Observations. In addition, clinical documents commonly contain
         Assessments, which are also kinds of Observations. Thus, the establishment of a diagnosis
         is an Observation.

      <definition value="An Act that of taking on whole or partial responsibility for, or attention to, safety

                           Discussion: A care provision event may exist without any other
         care actions taking place. For example, when a patient is assigned to the care of a particular
         health professional.

                        In request (RQO) mood care provision communicates a referral,
         which is a request:

                        
                           
                              from one party (linked as a participant of type author (AUT)),

                           
                           
                              to another party (linked as a participant of type performer
         (PRF),

                           
                           
                              to take responsibility for a scope specified by the code

                        The scope of the care for which responsibility is taken is identified
         by code attribute.

                        In event (EVN) mood care provision indicates the effective time
         interval of a specified scope of responsibility by a performer (PRF) or set of performers
         (PRF) for a subject (SBJ).

                              Assignment of a patient or group of patients to the case
