Overview

The Observation Occupation resource represents a patient's occupation. Occupation refers to the type of work a person does to earn a living or the principal activity that a person does for pay or profit. This resource captures patient-reported or clinically documented occupation information as part of comprehensive social history and social determinants of health data. At its minimum, Observation contains a specific LOINC code for occupation (11341-5), a status, a reference to the patient, and the occupation value, but may also contain data about the occupation period, industry, and related employment details.

Each Observation Occupation has next elements:

a status
a code for job history
a patient
the job code or text

Each Observation Occupation must support:

a category code of “social-history”
when the job occurred
a code for the job history industry
the industry code or text

This resource conforms to USCDI v3 profile for Occupation - refer to StructureDefinition US Core Observation Occupation Profile. Observation Occupation response will be provided in JSON (refers to Capability Statement) format as per FHIR standard R4 version.
