1 S: ActRootClass (ACT) 13856 ACT Act An action of interest that has happened, can happen, is happening, is intended to happen, or is requested/demanded to happen. An act is an intentional action in the business domain of HL7. Healthcare (and any profession or business) is constituted of intentional actions. An Act instance is a record of such an intentional action. Any intentional action can exist in different "moods". Moods describe activities as they progress in the business cycle, from defined, through planned and ordered to complete. Any instance of an Act assumes one and only one mood and will not change its mood along its life cycle. The moods - definition, intent, order, event - seem to specify a life cycle of an activity. However, the participants in the activity in these different moods are different, as is the data. Therefore, the mood of an Act instance is static. The progression actualization (i.e., the progression from defined, through planned and ordered, to being performed) is called the "business cycle" to distinguish it from the "life cycle" of a single act instance. Related Act instances that form such a "business cycle" are linked through the Act_relationship class. Examples for acts in health care are: a clinical test, an assessment of health condition (such as problems and diagnoses), the setting of healthcare goals, the performance of treatment services (such as medication, surgery, physical and psychological therapy), assisting, monitoring or attending, training and education services to patients and their next of kin, and notary services (such as advanced directives or living will). Acts have participants, which can be actors or targets. Examples of actors are nurses, doctors, family members, notary publics, and service organizations -- every person or organization that is capable of independent decisions and can thus is responsible (and liable) for the actions performed. Target participants in an act may include the patient, the patient's spouse, family, or community, a specimen drawn from the patient or from any object of interest. As patients do play active roles in their own healthcare, the patient can be both an active participant and a target participant at the same time (self-administered or reflexive services.) An act can have multiple active participants and multiple target participants, their specific role being distinguished in the "type_cd" of the respective instance of the Participation class. In particular, an act involving coordination of care may involve two or more active participants -- playing different roles -- who interact on behalf of a patient, family, or aggregate in the role of target participant. For example, a nurse (active participant) calls Meals on Wheels (active participant) on behalf of the patient (target participant). An act includes the "results", "answers" or informational "procedure products" gained during the act. In this model, "results" do not exist without an act, and every clinical result, including those results gained accidentally, is gleaned via an act. In other moods, such as "definition " or "intent", the results are the possible results, the expected or aimed-for results, or the tested-for results.

2   S: ActObservationClass (OBS) 11529 OBS Observation Observations are actions performed in order to determine an answer or result value. Observation result values (Observation.value) include specific information about the observed object. The type and constraints of result values depend on the kind of action performed. 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.

3     S: ActPublicHealthCaseClass (CASE) 11530 CASE Public Health Case 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.mood_cd = "definition") 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.
4       L:  (OUTB) 11531 OUTB Outbreak An outbreak represents a series of public health cases. 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.
3     L:  (ALRT) 16123 ALRT Alert An observation identifying a potential negative occurrence as a result of an Act or combination of Acts.
3     L:  (DGIMG) 13921 DGIMG Diagnostic Image Class for holding attributes unique to diagnostic images.
3     L:  (MPROT) 16230 MPROT Monitoring Program An officially or unofficially instituted program to track acts of a particular type or categorization.
3     L:  (REFCOORD) 16392 REFCOORD Referenced coordinate The Referenced_coordinate class is used to make reference to specific coordinates in images, waveforms or other datasets, for example, to specify the location of a radiologic finding or to identify the region on which a finding was based. For instance, clinicians can include graphical images in their notes, and "circle" a particular region of interest. This region of interest is than specifically referred to in their note. The relationship between a Referenced_coordinate and its referenced image is specified through an Act_relationship (using an Act_relationship.type_cd value of "REFV"). Referenced_coordinates are only meaningful in connection with a data object whose contents they reference. The units of the coordinate values are those of the referenced data object. For example, if the referenced object is a bitmapped image, the coordinates would be in pixel units. The presence of scaling parameters as attributes in a bitmapped image does not change the sampling coordinates: they remain in units of pixels. If the referenced object is a vector graphic figure specified in centimeters, the coordinate values are specified in centimeters.
2   S: ActSupplyClass (SPLY) 11535 SPLY Supply Supply orders and deliveries are simple Acts that focus on the delivered product. The product is associated with the Supply Act via Participation.type_cd="product". 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 Substance_administration Act. The Substance_administration class represents the administration of medication, while dispensing is supply.
3     L:  (DIET) 16109 DIET Diet Diet services are supply services, with some aspects resembling Medication services: the detail of the diet is given as a description of the Material associated via Participation.type_cd="product". Medically relevant diet types may be communicated in the Diet.cd attribute using domain ActDietCode, however, the detail of the food supplied and the various combinations of dishes should be communicated as Material instances.
2   S: ActWorkingListClass (LIST) 11541 LIST Working List Working_list collects a dynamic list of individual instances of Act via Act_relationship which reflects the need of an individual worker, team of workers, or an organization to manage lists of acts for many different clinical and administrative reasons. Examples of working lists include problem lists, goal lists, allergy lists, and to-do lists.

2   L:  (CEVN) 11534 CEVN Control event The Event is the focal point of information assembled in response to the occurrence of a "controlled event." "Participations" and "Acts" related to a "controlled event" ard assembled in a package with the RIM content that a domain technical committee specifies as the main payload of information to be communicated to document the event. This package can be placed in a message envelope, directed to an application managing documents or any application with component interfaces to this package of structured information content.
2   L:  (CONS) 11537 CONS Consent 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. 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 "signatures" to the consent document are represented electronically through Participation instances to the consent object. Typically an informed consent has Participation.type_cd of "performer" (the healthcare provider informing the patient, and "consenter", 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 Act_relationship.pause_qty attribute that delays the service until the pause time has elapsed after the consent has been completed.
2   L:  (CONTREG) 14005 CONTREG Container registration An Act where a container is registered either via an automated sensor, such as a barcode reader, or by manual receipt
2   L:  (CTXT) 11533 CTXT Act Context The Act_context is a specialization of an Act that explicitly contains a set of other Acts that share the same context. The "context" of an act is defined as the attribution ascribed to its containing Act_context.
2   L:  (ENC) 11542 ENC Encounter An interaction between a patient and healthcare participant(s) for the purpose of providing patient service(s) or assessing the health status of a patient. For example, outpatient visit to multiple departments, home health support (including physical therapy), inpatient hospital stay, emergency room visit, field visit (e.g., traffic accident), office visit, occupational therapy, telephone call.
2   L:  (PROC) 11532 PROC Procedure The term "procedure" is also commonly known as a "surgical procedure" or an "operative procedure". Typically, a surgical procedure involves planned alteration of the structure of the body, ordinarily requiring the disruption of some body surface, usually through an incision.
2   L:  (REFR) 11538 REFR Referral An introduction of a patient from a source caregiver to a target caregiver or provider institution, typically for the purpose of obtaining the target caregiver's assessment and treatment recommendations. A referral may authorize a specified quantity of a particular kind or level of service. A referral may also simply be a recommendation or introduction.
2   L:  (REG) 15932 REG Registration Represents the act of maintaining information about an entity or role in a registry. The class is most general, designed to support a variety of registries for persons, patients, practitioners, equipment, etc. If required, specific registry types will be treated as specializations of this class.
2   L:  (SBADM) 11528 SBADM Substance Administration Substance_administration is an Act using a Material as a therapeutic agent. The effect of the therapeutic substance is typically established on a biochemical basis, however, that is not a requirement. For example, radiotherapy can largely be described in the same way, especially if it is a systemic therapy such as radio-iodine.
2   L:  (SPCTRT) 14023 SPCTRT Specimen treatment A procedure or treatment performed on a specimen to prepare it for analysis
2   L:  (TRNS) 11539 TRNS Transportation Transportation is the moving of a payload (people or material) from a location of origin to a destination location. Thus, any transport service has the three target instances of type payload, origin, and destination, besides the targets that are generally used for any service (i.e., performer, device, etc.)
