FHIR R4 Questionnaire API

Overview

This asset is a component of MuleSoft Accelerator for Healthcare.

MuleSoft Accelerator for Healthcare enables healthcare providers to unlock critical patient data to build a patient 360 within Salesforce Health Cloud, faster and easier than ever before. The solution includes pre-built APIs, connectors, integration templates, and prescriptive end-to-end reference architecture to bring patient demographics information and COVID-19 test results from any EHR into Health Cloud using HL7 V2 or FHIR standards.

The solution also provides a library of United States Core Data for Interoperability (USCDI) and FHIR R4 resources to help healthcare developers adhere to interoperability needs and jumpstart the development of healthcare digital transformation initiatives.

Use case covered

A Questionnaire is an organized collection of questions intended to solicit information from patients, providers or other individuals involved in the healthcare domain. They may be simple flat lists of questions or can be hierarchically organized in groups and sub-groups, each containing questions. The Questionnaire defines the questions to be asked, how they are ordered and grouped, any intervening instructional text and what the constraints are on the allowed answers. The results of a Questionnaire can be communicated using the QuestionnaireResponse resource.

Questionnaires cover the need to communicate data originating from forms used in medical history examinations, research questionnaires and sometimes full clinical specialty records. In many systems this data is collected using user-defined screens and forms. Questionnaires define specifics about data capture - exactly what questions were asked, in what order, what choices for answers were, etc. Each of these questions is part of the Questionnaire, and as such the Questionnaire is a separately identifiable Resource, whereas the individual questions are not. (Questionnaire questions can be linked to shared data elements using the Questionnaire.item.definition element.)

Examples of Questionnaires include:

• Past medical history (PMH)
• Family diseases
• Social history
• Research questionnaires/Clinical research forms (CRFs)
• Quality and evaluation forms
• Patient intake form (e.g. clipboard)
• Forms to support insurance claims

This resource is limited in scope to support the characteristics of simple questionnaires. However, common extensions have been defined to allow more sophisticated behavior. This includes:

• Questionnaire core extensions which defines the additional descriptive characteristics for questionnaires and their groups and questions
• Element extensions which can describe additional constraints on allowed answers for questionnaires such as string length and date and numeric ranges

Additional implementation guides, in particular the Structured Data Capture Questionnaire IG provide guidance, extensions and operations that support additional capabilities and allow the definition of more sophisticated questionnaires and their corresponding responses.

This API uses FHIR R4 Questionnaire Library.
