Connecticut ranked fourth nationwide for the percentage of acute-care hospitals rated with an A grade for safety in the latest scorecard released by the independent, not-for-profit Leapfrog Group.

The fall 2025 Health Safety Grade report, a biannual safety analysis, assigns an A, B, C, D or F grade to all general hospitals in the United States based on their ability to protect patients from medical errors, accidents, injuries and infections.

These largely preventable problems harm one in four hospital inpatients and cause as many as 250,000 deaths each year, the report states.

Leapfrog graded 28 acute-care hospitals in Connecticut and 13, or 46%, were rated with an A. That placed the state fourth in the country for its percentage of A-rated hospitals, behind Utah, Virginia and New Jersey and just ahead of North Carolina.

The 13 Connecticut hospitals that received an A grade are Danbury Hospital; Greenwich Hospital; Griffin Hospital in Derby; Hartford Hospital; Hospital of Central Connecticut in New Britain; Johnson Memorial Hospital in Stafford Springs; Middlesex Hospital in Middletown; MidState Medical Center in Meriden; St. Mary’s Hospital in Waterbury; St. Vincent’s Medical Center in Bridgeport; UConn Health Center/John Dempsey Hospital in Farmington; William Backus Hospital in Norwich; and Windham Hospital.

Five Connecticut hospitals received a safety grade of B, eight were graded C, and one — Day Kimball Hospital in Putnam — received a grade of D.

Yale New Haven Hospital and St. Francis Hospital in Hartford were among those receiving a grade of C.

The Leapfrog analysis found that 90% of hospitals with a fall 2025 Safety Grade are part of a health system. It also found that among the hospitals graded A, the chance of being affiliated with a health system was slightly higher, at 94%.

Utah held the top spot in the state rankings for the fifth straight report. In contrast, Iowa, North Dakota, Vermont and Wyoming had no A-graded hospitals.
