Designing a Healthcare Semantic Model in Power BI: Trustworthy Dashboards, Predictable Refresh, and Privacy That Holds
Hospitals don’t need flashier visuals; they need answers they can trust at the point of care. When Power BI projects mirror source systems or bury privacy behind permissions, dashboards slow down, clinicians lose trust, and ops revert to spreadsheets.
This article lays out a healthcare-first approach to Power BI: a semantic model that reflects clinical reality (encounters at the right grain, vitals/labs as events), performance patterns that survive peak hours (Incremental Refresh, Aggregations, Composite models), and safety rails on the surface (freshness, completeness, RLS, governed exports).
A focused 30-day plan closes things out so you can harden one high-impact dashboard without pausing delivery.
