StructureDefinition-us-core-condition

This profile sets minimum expectations for the Condition resource to record, search and fetch a list of problems and health concerns associated with a patient. It identifies which core elements, extensions, vocabularies and value sets SHALL be present in the resource when using this profile.

Example Usage Scenarios:

The following are example usage scenarios for the US Core-Condition profile:

  • Query for a Patient’s current or historical problems
  • Record or update a Patient’s problem
Mandatory Data Elements and Terminology

The following data-elements are mandatory (i.e data MUST be present). These are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Profile Definition below provides the formal summary, definitions, and terminology requirements.

Each Condition must have:

  1. a status of the problem
  2. a verification status
  3. a category
  4. a code that identifies the problem
  5. a patient

Profile specific implementation guidance:

  • The US Core Condition Category Codes support the separate concepts of problems and health concerns so API consumers can separate health concerns and problems. However this is not mandatory for 2015 certification
  • The 2015 Certification rule requires the use of SNOMED CT for problem list entries. Following the rules for extensible binding to coded data types, ICD or other local codes can be used as translations to or in addition to SNOMED CT.

Examples

  • Condition-hc1 is an example of a condition categorized as a “problem”
  • Condition-example is an example of a condition categorized as a “health-concern”

Quick Start

Below is an overview of the required set of RESTful FHIR interactions - for example, search and read operations - for this profile. See the Conformance requirements for a complete list of supported RESTful interactions for this IG.

GET /Condition?patient=[id]

Example: GET [base]/Condition?patient=1032702

Support: Mandatory to support search by patient.

Implementation Notes: Search for all problems and health concerns for a patient. Fetches a bundle of all Condition resources for the specified patient. (how to search by reference) and (how to search by token).

GET /Condition?patient=[id]&clinicalstatus=active,recurrance,remission

Example: GET [base]/Condition?patient=1032702&clinicalstatus=active,relapse,remission

Support: Optional to support search by status.

Implementation Notes: Search for all active problems and health concerns for a patient. Fetches a bundle of all Condition resources for the specified patient and all “active” statuses (active,relapse,remission) (how to search by reference) and (how to search by token). This will not return any “entered in error” resources because of the conditional presence of the clinicalStatus element.

GET /Condition?patient=[id]&category=problem

Example: GET [base]/Condition?patient=1032702&category=problem

Support: Optional to support search by patient and category.

Implementation Notes: earch for all Problems for a patient. Fetches a bundle of all Condition resources for the specified patient with a category code of “problem” (how to search by reference) and (how to search by token).

GET /Condition?patient=[id]&category=health-concern

Example: GET [base]/Condition?patient=1032702&category=health-concern

Support: Optional to support search by patient and category.

Implementation Notes: Search for all Health Concerns for a patient. Fetches a bundle of all Condition resources for the specified patient with a category code of “health-concern”(how to search by reference) and (how to search by token).
