Overview

Observation SDOH Assessment Survey is represented using Observation FHIR Resource. Observations are a central element in healthcare, used to support diagnosis, monitor progress, determine baselines and patterns and even capture demographic characteristics, as well as capture results of tests performed on products and substances. Most observations are simple name/value pair assertions with some metadata, but some observations group other observations together logically, or even are multi-component observations. Each Observation supports next elements:
  • a category code of sdoh
  • an SDOH LOINC code, if available
  • references to other US Core SDOH assessments
Profile specific implementation guidance:
  • This profile defines a Valueset based on a starter set of example survey LOINC codes made up of commonly asked social questions as identified by FindHelp.org and the PRAPARE, Hunger Vital Sign, AHC-HRSN screening tools referenced in USCDI v2. It is not intended to be complete and implementers are expected include other LOINC or other codes to meet their business needs.
  • See the US Core Observation Survey Profile page for how to represent individual responses, panels of multi-question surveys, and multi-select responses to “check all that apply” questions, and other implementation guidance.
  • See the SDOH guidance page for how this profile along with other Observation Profiles or alternatively QuestionnaireResponse to is used represent SDOH assessments.
This resource conforms to USCDI V2 profile for Observation - refer to US Core Observation SDOH Assessment Profile. Observation response will be provided in JSON (refers to Capability Statement) format as per FHIR standard R4 version.
