The Catalog Entry resource (formally known as Entry Definition) allows additional information specification for items that may be found in the following types of clinical collections, including but not limited to:
– A pharmacy formulary
– A laboratory compendium
– A radiology compendium of exams that may be ordered
– A dietary nutrition order catalog
– A supply charge master
– A CDS (Clinical Decision Support) catalog of knowledge artifacts
The Catalog profile of the composition resource is used to organize catalog entries.
Catalogs are composed of nestable sections which contain catalog entries. Catalog entries wrap the items that are orderable or selectable in a catalog and any other required supporting entries. Examples of information provided by Catalog Entry includes whether the status of the item in the catalog is “active”, “inactive”, “legacy”, or “informative” or whether the item is an orderable item in the context of this catalog (or catalog section). the relation between the item and other items (“contains”, “includes”, “requires”). Catalog entries also support relationships to other catalog entries such as whether a product is now replaced by another product in a product catalog.
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.
