Data Studies
Original analyses of US nursing homes and care quality, built from CMS Care Compare. Free to reference — please cite with a link back to CareLens.
CMS publishes annual nursing staff turnover for every nursing home and almost no consumer site shows it. The national average, how turnover tracks with star ratings at every level, the for-profit vs nonprofit gap, and all 50 states ranked.
Every US state ranked by average CMS hospital overall star rating — where hospital quality is highest and lowest, the share of 1-star vs 5-star hospitals nationally, and the full state-by-state breakdown.
What share of US nursing homes carry CMS's lowest 1-star rating — the national 1-star vs 5-star split, the states with the weakest average ratings, and the largest low-rated facilities nationally.
How often patients land back in the hospital within 30 days — readmission rates for all six conditions CMS measures, every state ranked on the risk-adjusted excess readmission ratio, and a for-profit vs nonprofit comparison.
Most surgery no longer happens in a hospital. We audited every safety measure CMS publishes for all 5,600+ ambulatory surgery centers — and found a reporting regime that identifies a single-digit number of facilities nationally as better or worse than expected.
