         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,

                    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."/>

             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
             syndrome, and salmonellosis and their associated indicators that are used to define a

           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

           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 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."/>

           are therefore &quot;exposed&quot; to a medicine that there was no therapeutic indication
           for them to receive.

                       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.

           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.

           the surgical wound site after the surgery.

            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.

           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.                  
                                                                                                
                                                                                Usage Notes: This
           class deals only with opportunity and not the outcome of the exposure; i.e. not all exposed
           parties will necessarily experience actual harm or benefit.                          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:                   
                                                                            The exposed entity participates
           via the &quot;exposure target&quot; (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)."/>

           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,

               need not be specified if the respective dimension is only named but not constrained. For

            <definition value="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&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. 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."/>

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

                   The scope of the care for which responsibility is taken is identified by code
           attribute.                          In event (EVN) mood care provision indicates the effective
