HSSP Order Service Interface Specification Project

Project Scope

The proposed Ordering Service is intended to complement existing SOA services and the SAIF Behavioral Framework (BF) for HL7. It will provide a Service Functional Model (SFM) for ordering pharmacy, laboratory, radiology, consult and nutritional services individually or part of an order set. The Ordering Service is intended to support interactive applications utilized by healthcare providers, and service-to-service interactions as might be required by a Clinical Decision Support system.

Pre-existing conceptual work in topics such as Composite Orders, Laboratory Orders, Nutrition, Medication, or FHIR Order and Prescription resources will be leveraged extensively to help document the necessary definitions, descriptions, graphics, and artifacts that are relevant. In keeping with the approach used by the above referenced projects, the Ordering Service will distinguish between the order itself and the item requested. The Service Interface Specification will provide functional, semantic, and conformance profiles.
