30-Day Hospital Readmission Analysis


A personal healthcare analytics portfolio documenting my journey from raw CMS data to interactive Power BI dashboards.

This project uses real CMS Medicare Hospital Compare data to analyze 30-day hospital readmission rates. Through this project, I practiced importing, cleaning, analyzing, and visualizing real CMS Medicare healthcare data using SQL Server and Power BI.

Technologies:

  • SQL Server
  • Power BI
  • CMS Hospital Compare Dataset

Current Progress

  • ✅ Downloaded and imported CMS Medicare Hospital Compare data into SQL Server
  • ✅ Cleaned and validated the dataset using SQL
  • ✅ Explored hospital readmission data using SQL queries and aggregate functions
  • ✅ Built an interactive Power BI dashboard
  • 🔄 Continuing to expand SQL skills with Window Functions and CTEs

What I’m Learning

  • Working with real CMS healthcare datasets
  • Writing SQL queries for healthcare data analysis
  • Building an end-to-end analytics workflow from raw data to Power BI dashboards
