Logical Model: Instruction Observation

The Instruction observation template can be used in several ways, such as to record patient instructions within a Medication Activity or to record fill instructions within a supply order. Though not defined in this template, a Vaccine Information Statement (VIS) document could be referenced through observation/reference/externalDocument, and patient awareness of the instructions can be represented with the generic participant and the participant/awarenessCode.

The value element represents the actual instructions given to the patient. Typically recorded as a string or a narrative reference, the value may also be coded, though this template enforces no limits on the set of codes that can be used.

Usage:

• Use this Logical Model: Immunization Activity, Instructions Section, Intervention Act, Medication Activity... Show 9 more, Medication Supply Order, Non-Medicinal Supply Activity, Planned Immunization Activity, Planned Intervention Act, Planned Medication Activity, Planned Procedure, Planned Supply, Plan of Treatment Section and Procedure Activity Procedure
