This resource applies to various circumstances where there is a concern about an existing or proposed set of clinical activity. The issue could relate to single, proposed, or multiple actions. It does not apply to technical issues (e.g. lack of user permissions) but could relate to a violation of patient consent limitations. Examples include:
– Drug-drug interactions
– Inappropriate therapy (wrong dose, frequency, body site)
– Duplicate therapy
This resource represents a specific instance of a potential issue for a particular patient. It is not intended to represent general patient-independent knowledge. This resource is also not intended to be used in defining general prohibitions on actions such as “No NSAIDs (Nonsteroidal anti-inflammatory drugs)”, “No solid oral dose forms” or “No MRIs (Magnetic resonance imaging) – metallic tattoos”. These guidelines can be captured using the AllergyIntolerance, and/or Flag resources. Similarly, this resource is not to be used to capture clinical facts that may imply contraindications such as pregnancy, breastfeeding, patient preferences, past procedures, etc. These would be represented using Condition, Procedure or other resources.
Fast Healthcare Interoperability Resources (FHIR) is a draft standard describing data formats and elements (known as “resources”) and an application programming interface (API) for exchanging electronic health records. The standard was created by the Health Level Seven International (HL7) health-care standards organization.
Its goal is to facilitate interoperation between legacy healthcare systems, to make it easy to provide healthcare information to healthcare providers and individuals on a wide variety of devices from computers to tablets to cell phones, and to allow third-party application developers to provide medical applications which can be easily integrated into existing systems.
FHIR provides an alternative to document-centric approaches by directly exposing discrete data elements as services. For example, basic elements of healthcare like patients, admissions, diagnostic reports and medications can each be retrieved and manipulated via their own resource URLs (Uniform Resource Locators). FHIR was supported at an American Medical Informatics Association meeting by many EHR (Electronic Health Record) vendors which value its open and extensible nature.
