QI-Core Implementation Guide
5.0.0 - STU5 United States of America flag

This page is part of the Quality Improvement Core Framework (v5.0.0: STU5 (v5.0.0)) based on FHIR R4. The current version which supercedes this version is 4.1.1. For a full list of available versions, see the Directory of published versions

Resource Profile: QICore Observation Survey

Official URL: http://hl7.org/fhir/us/qicore/StructureDefinition/qicore-observation-survey Version: 5.0.0
Active as of 2022-04-20 Computable Name: QICoreObservationSurvey

The QI Core Observation Survey Profile is based upon the US Core Observation Survey Profile which can be used to represent individual responses, panels of multi-question surveys, and multi-select responses to “check all that apply” questions. The QI Core Observation Survey Profile sets minimum expectations for the Observation Resource to record, search, and fetch retrieve observations that represent the questions and responses to form/survey and and defines the core set of elements and extensions for quality rule and measure authors.

Guidance

Reference Guidance for use of the Observation Survey profile can be found here.

  • See the Social Determinants of Health (SDOH) Guidance Page for how this profile along with other Observation Profiles or alternatively QuestionnaireResponse to is used represent SDOH assessments.
  • The US Core Observation Social History Profile should be used for individual clinical assessments made by an individual about a patient’s social history which array_to_sentence_string not derived from an assessment tool or survey.

Usage

See the patterns page for implementation and usage patterns.
