RADAR-base (Remote assessment of Disease and Relapses) is an open source platform to leverage data from wearables and mobile technologies. The main focus of RADAR-base is seamless integration of data streams from various wearables to collect sensor data in real time and store, manage and share the collected data with researchers for retrospective analysis.

To conduct a remote monitoring study using RADAR-Base, you need to have a deployment of RADAR-base platform either in-house or on cloud, integration of selection of devices you would like to use for your study. Once these are available, you can start enrolling participants with the help of our study management system called ManagementPortal.

If you are in this page and want to try out RADAR-base in your phone or with your devices, please read our Getting Started page before proceeding. This demo is facilitated by TheHyve.

Getting started with passive remote monitoring with RADAR-Base

To conduct a remote monitoring study using RADAR-Base, you need to have a deployment of RADAR-base platform either in-house or on cloud, integration of selection of devices you would like to use for your study. Once these are available, you can start enrolling participants with the help of our study management system called ManagementPortal.

ManagementPortal (MP) is a web application to manage studies, participants and devices or applications used by participants. It provides role based access control (RBAC) levels for the users such as system-admin, project-admin, participant etc. This means that data access is granted or restricted based on the roles and the projects a user is assigned to. This ensures that only authorized personnel can access the research data. The first step of managing a study/trial with RADAR-base is to create a Project. All users, participants, devices and data collected are categorized based on projects.

A participant is represented as a Subject in RADAR-base and any data source that sends the data to the platform is referred as s Source e.g. a wearable device or a mobile app. To allow secure data transmission, RADAR-Base allows only the known subjects to send data from known devices or applications to the platform. This process is facilitated by the participant on-boarding process. Please read this blog for more information about study management in RADAR-base. Following, you will find instructions to install the pRMT application on your Android phone and enroll one or more participants to a study.

We will use a platform set-up for demo purposes by TheHyve. Creating a new project can be done by a user with system admin privileges. For this demo, we will create a project for you. Please contact the RADAR-base team from TheHyve, by simply dropping an email. The demo projects are provided for free and the account do not expire unless requested. If you already have your credentials, you can proceed to with the following steps.

Step 1. Download and Install RADAR-Base pRMT from Android playstore.

Please go to the playstore on your Android phone and search for “RADAR passive RMT” and install the application. Once installed you will see “Scan QR code” screen on your phone.

Step 2. Login into ManagementPortal.

  1. You should have received an email to activate your account from ManagementPortal team. Please activate your account by resetting your password.
  2. Login to ManagementPortal using username and password provided here. (Please contact us if you cannot login successfully)
  3. Once logged in you will see the projects accessible to you. Click on the View button to go to your project view. The project view gives information about the relevant project, subjects (participants) and sources (apps and devices connected to the project) and users.

Step 3. Participant on-boarding

The participant on-boarding process is quite easy and can be done with a few clicks and scanning a QR code generated by the system.

  1. To start with the sys-admin/project admin has to create a new subject to add a new participant to the study. Click on Create a new Subject on your study view.
  2. By default you don’t have to enter any details here. However, we recommend you to mention an unique External id (ideally one that  refers to an identifier from an external system such as identifiers from your local user-management system) to easily identify your subject from the others. Click on Save to create the subject.
  3. You will see a new subject created which displays your external id.
  4. (Optional) Add additional devices like Empatica E4 to the participant. See Appendix I.

Step 4. Generate QR code for your participant

  1. Click on Pair App on the subject you created.
  2. You will see a pop-up. From the Client app drop-down, choose pRMT. Then you will see a QR code generated for you.

Step 5. Scan QR code from pRMT app and provide permissions

  1. Open the pRMT app you have installed on your phone and click on Scan QR Code. Then scan the QR code generated in the system.
  2. Allow the application to take pictures and video which will allow the application to scan the QR for you, read and accept the privacy policy, then allow application to manage requested applications to collect data. Once done, you will see a your phone connected to the platform.

This will enable RADAR-base to collect sensor data from your Android phone.

Appendix I: Adding additional devices to participant with pRMT

In addition to the sensor data and application data from your Android phone, you can use one of the supported wearable devices which sends data to pRMT application via bluetooth such as Empatica E4 or Faros to try out RADAR-Base. Follow the steps below to add additional devices. The following example shows how to add an Empatica E4 device to a participant.

  1. Click on SOURCES tab from the left column.
  2. Then click on Create a new Source, add the serial number of Empatica E4 as the physical ID. The Source name should be a unique value. You can use the serial number as the source name too. Lastly select E4 as the source-type, then click Save.
  3. Now you are going to assign this device to the participant. Click on SUBJECTS from the left column to navigate back to the list of participants. Then click on Pair Sources.
  4. You will see a pop-up with a list of available sources. Click on the Add button next to the source (with the physical id/ source name you mentioned) and then Save.
  5. You will see that it is moved to Assigned sources.

Finally, please follow Step 4 and 5 to generate a QR code and scan it from your Android phone.

Please contact TheHyve to get the raw data files for your project or subject (participant).
