FHIR-based Order Template API Definition: Disease-Specific Plan Search

Details

This page is an excerpt from an API reference obtained from the NCCN website, detailing an endpoint for retrieving definitions of 'Order Templates.' Specifically, it shows a GET endpoint that uses the FHIR format. By utilizing this API, developers can programmatically retrieve a list of treatment plan templates (PlanDefinition) by specifying keys such as a specific disease (`disease` parameter) or external disease ID (`ExternalDiseaseId` parameter). This functionality is highly valuable for integration into clinical order entry support systems and Electronic Health Records (EHRs). Technically, the request parameters include page number (`page`), count limit (`_count`), and search criteria such as disease information. The response is provided in JSON format, containing a list of retrieved templates. This structure leverages FHIR, a standardized medical data exchange format, which holds significant importance for facilitating interoperability and linking treatment protocols or order flows across different systems. In the Japanese healthcare IT environment, acquiring standard clinical guidelines (order templates) via an API based on disease information and integrating them into EHRs or support systems is crucial for improving operational efficiency and care quality. This specification provides concrete technical guidance for achieving that goal.
