According to the Salesforce documentation1, the Health Cloud Reports for Patient Referral Management is an unmanaged extension package that provides a prebuilt dashboard with reports on important aspects of referral management, such as referral status, referral source, referral age, and referral efficiency. The package also includes custom fields, custom objects, and custom report types to support the dashboard. To use this package, a consultant should install it in their org and assign the appropriate permissions to the users who need to access the dashboard. The package is compatible with Health Cloud and CRM Analytics.

The FHIR-Aligned Data Model org preference is the preference that Bloomington Caregivers' administrator should ensure is enabled to use the objects for the Clinical data model as part of its new Health Cloud implementation. This preference enables the Clinical data model, which is a FHIR R4-aligned data model that captures information from an Electronic Health Record (EHR) system via integration middleware1. The Clinical data model is built on Salesforce core, with no reference to package entities, and supports only the attributes that Health Cloud users need, not all attributes in every FHIR R4 resource2. The Clinical data model is the successor to the original EHR Data Model, which was built on the managed package and followed the FHIR R1 standard2.
