The Biorepository Portal contains a docker-compose file which defines a brp service to quickly spin up a demonstration instance of the portal. This demo consists of the Portal itself, redis, as well as a companion instance of electronic Honest Broker.
Run:
docker-compose up brp
Demonstration accounts for both the Portal and the eHB have a user name of [email protected] and a password of Chopchop1234 (case sensitive).
The Biorepository Portal (BRP) is the main client for the Electronic Honest Broker. It provides an interface that displays protocols with associated patients and systems (also called datasources) that each patient has a record in. It can also, depending on the datasource driver, provide an interface within the application to that datasource, or link out to the system externally. An example of an application embedded within the driver would be the REDCap form interface provided within the BRP. An example of a driver that just links out to an external system is the phenotype intake driver.
This biorepository-portal presents a unified interface that shows protocol names, the patients on each protocol, and the external systems that each patient on each protocol has records in. To accomplish this, it accesses the ehb-service where all Protected Health Information (PHI) and identifiers used in external systems are actually stored. See the wiki for implementation details and for a better understanding of services provided by the BRP versus services provided by the ehb-service.
A user logs into the BRP and sees a list of Projects (Protocols) they have access to, which is determined by Protocol User objects.
They click on a Protocol and see a list of Patients in that protocol. Next to each patient, there is a button for each external system (also called Datasource) on that Protocol. These buttons are configured by creating a Protocol Datasource object. Whether or not a button is enabled (clickable) depends on whether the logged in user has credentials in the system for the associated Datasource, which is configured by creating a Protocol User Credentials object. This associates a User and a Protocol Datasource (see the next section for details). Clicking on a given button brings up a page with a list of records that the patient has on that external system (or shows an empty list if the patient has no records yet), and a button to create a new record.
Clicking on a given record in that list opens up a page controlled by the datasource driver. This could show an entire embedded application (in the case of the REDCap driver) or just link out to an external system.
Patients can be added to a Protocol on the Protocol Screen by clicking the "Add Subject" button. This makes a request to the ehb-service adding the user to the Protocol and creating the user in the system if they do not exist yet.
Whether or not the user already exists in the ehb-service system is determined by the MRN (organization wide patient identifier). This patient information, while added using the biorepository-portal is not stored in the biorepository-portal's database, it just tells the ehb-service to add the user to the Protocol. Later on, to display the Protocol page that lists users on a Protocol, the biorepository-portal will ask the ehb-service for all patients on the Protocol, and list them on the page, but it does not store that information. This is a slight simplification of the process, see the wiki for more details.
Organizations have one or more Protocols. Multiple organizations may be on the same protocol. To link Datasources with a Protocol, you create a Protocol Datasource. For example, there may be protocol called Study A linked to organizations CHOP and Boston's Children's with 1 REDCap Datasource (tied to the Protocol by creating a Protocol Datasource linking the REDCap Datasource with Study A).
Finally, user credential objects are tied to the Protocol Datasource object. For each user that might login, you need to configure credentials for each external system on each protocol they need to access. For example, if you have a Protocol with a REDCap Datasource, you will need to set the user's REDCap API key in a Protocol User Credentials object. This ties together the User, the Protocol, the Datasource, and the API key credential. If that is not done than the button to the REDCap Datasource will be disabled.
Datasources are defined in the biorepository-portal, but the drivers that access those datasources are defined in the ehb-datasources repository.
To add a new type of driver, you need to add it to the list in
brp/apps/portal/models/protocols.py.
