Participant System

Overview

The Participant system is the core system of the RDR. All other systems integrate with the Participant System either directly or indirectly. Participants are initially created via the Participant Portal. Participants are amended and modified with data from the Data Capture system, generally through the HealthPro client or the Participant Portal.

Participant data is aggregated and delivered to analysts by the Reporting system.

Data Flow

A participant is first created when data is submitted through the Participant Portal client. A POST request with an empty JSON payload will create a participant record in the participant table.

Various questionnaires may be presented to the participant by a clinician via the HealthPro client. Any data captured here will be associated to the participant in the questionnaire_response and questionnaire_response_answer tables.

Workflows

Creating

Participants are created via the Participant Portal.

Updating

Participants are modified through the Data Capture system, which associates questionnaire, EHR, and measurement data and updates participant status. API workflows can be seen here: Creating and Updating Participant Data.

Reading

Data from the Participant system is commonly read through the Participant Summary.
