21. What Is Power BI?
Power BI is Microsoft’s powerful business intelligence tool used to visualize and analyze data. It allows users to connect to various data sources, create interactive reports and dashboards, and gain insights through charts, graphs, and KPIs. In healthcare, Power BI is widely used to analyze claims data, track quality measures, and monitor risk adjustment performance.
22. Data Modeling Basics
Data modeling is the process of organizing tables and defining relationships between them. A well-designed data model (often using a star schema) makes reports faster and more accurate. Key concepts include:
- Fact tables (containing measurable data like costs or counts)
- Dimension tables (containing descriptive data like member demographics or dates)
23. Measures vs Calculated Columns
- Calculated Columns: Computed row by row during data refresh. They take up storage space.
- Measures: Calculated dynamically when used in visuals. They are more efficient and flexible, especially for aggregations like SUM, COUNT, AVERAGE, or complex calculations (e.g., RAF score per member).
24. Dashboards vs Reports
- Reports: Multi-page, detailed documents with many visuals and filters. Good for in-depth analysis.
- Dashboards: Single-page, high-level summary view with key metrics. Designed for quick monitoring and executive overviews.
25. Healthcare Analytics KPIs Common healthcare KPIs include:
- Average RAF Score
- HCC Capture Rate
- Coding Accuracy Rate
- Risk Score Distribution
- Chronic Condition Prevalence
- Cost per Member per Month (PMPM)
- Readmission Rates
- Quality Measure Performance (HEDIS, Stars Ratings)
