Specification Details for Questionnaire Response Resource in HIEBus FHIR Interface

Details

This document details the specification of the Questionnaire Response resource based on FHIR version 4.0.1 (R4). This resource is used to represent 'a structured set of questions and responses,' enabling the standardized exchange of clinical data between medical institutions. The HIEBus interface defines related resources such as QuestionnaireResponseItem and QuestionnaireAnswer. Technically, this resource supports standard CRUD operations: create, delete, read, search, and update. It provides advanced search capabilities using parameters like `_id`, `patient` (reference), and `encounter` (encounter reference), allowing for efficient data filtering and extraction. Furthermore, it includes options to retrieve only specific elements or estimate the total number of results. In the context of Japanese healthcare IT, standardizing data using FHIR is crucial. The release of these specifications provides a technical guideline for various systems—such as electronic medical records (EMR) and regional cooperation systems—to exchange data using a common data model (Questionnaire Response), directly contributing to improved interoperability.
