Step-by-Step Explanation:

Health Cloud Best Practice for Displaying Internal and External Data:

FlexCards (part of OmniStudio) can display data from multiple sources in a unified view on a patient record.

Integration Procedures connect to external systems and bring in data (e.g., from EHRs or other sources).

DataRaptors extract and transform Salesforce data for display and use in FlexCards.

Salesforce Documentation Reference:

“FlexCards can display internal Salesforce data and call Integration Procedures or DataRaptors to bring in external or standard object data.” — OmniStudio Standard Guide

“Integration Procedures are used to retrieve and update data from external systems and can be invoked directly from FlexCards or OmniScripts.” — OmniStudio Integration Procedures

“DataRaptors map Salesforce data to and from FlexCards and Integration Procedures, enabling seamless display of patient information.” — OmniStudio DataRaptors

Other Options:

Salesforce Flows : Good for automation but not for real-time display of combined external and internal data on record pages.

Visualforce Pages : Legacy solution, not recommended for modern Health Cloud patient page display, and does not natively integrate with OmniStudio tools.
