Release Notes: PIA Version 1.38.1

iPIA export for an entire study

Subject managers can now export all iPIA data for an entire study in a CSV file. This includes important IDAT data such as usernames, contact details, contact blocks and revocations so that the current status can be viewed before follow-up examinations.

Optional linking of questionnaire reminders to the questionnaire overview

A new feature makes it possible to optionally set the link in questionnaire reminders to the questionnaire overview instead of directly to the questionnaire. This is particularly useful if a reminder is to apply to several questionnaires. A new checkbox in the questionnaire editor makes it possible to activate this option. When enabled, both notifications and emails will take users to the questionnaire overview instead of directly to a specific questionnaire.

Set the order of questionnaires in the participant view

Researchers can now define the order in which the questionnaires are displayed to participants under the "Questionnaires" tab. An ordinal number can be entered in the questionnaire editor, which determines the order in which the questionnaires are displayed. Questionnaires with lower numbers appear higher up in the list. If no ordinal number is entered, these questionnaires are positioned at the end of the list. This sorting is fixed for participants and cannot be changed by them. The ordinal number is also displayed in the overview for professional roles.

Customizable cycles for questionnaire reminders

Researchers can now customize the cycle of questionnaire reminders to remind participants of their tasks in a more targeted manner. In addition to the previous option of defining the frequency of reminders, a fixed interval between reminders can now also be defined in days or hours. This function, which already exists for cyclical questionnaires, is now also available for one-off questionnaires, allowing the reminder intervals to be configured individually.

Switch to the new FCM API for push notifications

PIA's push notification interface has been successfully migrated to the new FCM API, as the legacy API previously used by Firebase has been discontinued. The migration was technically straightforward as the firebase-admin package used already supports the new API. To ensure that push notifications continue to work reliably, the command call and error handling have been adapted.

Keycloak Update to v24

The Keycloak system has been updated to version 24.

PIA Public API

This is the first release of the PIA Public API. This API provides endpoints for integrators and developers to connect third-party applications with PIA. Below is a summary of the key features and endpoints included in this release:

Description of available Endpoints

• Event History: Operations related to the event history. PIA uses a message queue for inter-service communication. Messages classified as events can be stored for a configurable duration and retrieved if enabled by a SysAdmin.

• Questionnaire Instances: Questionnaire instances are shown to participants and always belong to exactly one participant. A questionnaire instance is valid for a period of time specified in the underlying questionnaire.

• Answers: An answer is the value that a participant has given to a question in a specific questionnaire instance.

• Participants: A participant can answer questionnaire instances and is always part of exactly one study.

• Security: The PIA Public API uses OAuth2 for authentication.
