9 CT Hospitals Earn Either ‘D’ Or ‘C’ Grade In New Safety Ranking: Here Is The Full List
CONNECTICUT — A new hospital safety report released Thursday shows 14 hospitals in Connecticut earned “A” grades based on their ability to protect their patients from often preventable harm.
The Leapfrog Group’s Fall 2025 Hospital Safety Grades are a biannual ranking that assigns a “A,” “B,” “C,” “D” or “F” to all general hospitals in the United States based on their ability to protect patients from medical errors, accidents, injuries and infections. The Leapfrog Group, a watchdog founded 25 years ago, says it aims to improve American health care through transparency.
The report also named “Straight A” hospitals — those earning an A grade for more than two years in a row.
Medical errors, accidents, injuries and infections are largely preventable problems that harm one in four hospital inpatients and cause as many as 250,000 deaths each year, according to The Leapfrog Group. The Safety Grade reports have been a cornerstone of that effort, the group says.
Here are the hospitals in Connecticut that earned A grades (“Straight A” hospitals are in boldface):
- Danbury Hospital
- Greenwich Hospital
- Griffin Hospital, Derby
- Hartford Hospital
- Johnson Memorial Hospital, Stafford Springs
- Middlesex Hospital, Middletown
- MidState Medical Center, Meriden
- Saint Mary’s Hospital, Waterbury
- Sharon Hospital
- St. Vincent’s Medical Center, Bridgeport
- The Hospital of Central Connecticut, New Britain
- The William W. Backus Hospital, Norwich
- University of Connecticut Health Center, John Dempsey Hospital, Farmington
- Windham Community Memorial Hospital, Willimantic
Additionally, five hospitals in Connecticut earned B grades:
- Bridgeport Hospital
- Charlotte Hungerford Hospital, Torrington
- New Milford Hospital
- Norwalk Hospital
- Stamford Health
Eight received C grades:
- Bridgeport Hospital Milford Campus
- Bristol Health
- Lawrence & Memorial Hospital, New London
- Manchester Memorial Hospital
- St. Francis Hospital & Medical Center, Hartford
- Waterbury Hospital
- Yale New Haven Hospital – Saint Raphael Campus
- Yale-New Haven Hospital
…and one received a D grade:
- Day Kimball Hospital, Putnam
The Leapfrog Group for the first time in the history of its report cards looked at the performance of hospitals that are part of larger networks of health care facilities that are owned or managed under a single parent organization.
“We want to understand if system leadership accelerates patient safety or not,” Leah Binder, Leapfrog’s president and CEO, said in a news release.
The analysis found that 90 percent of hospitals with a fall 2025 Safety Grade are part of a health system. Among A hospitals, the chance of being system-affiliated is slightly higher, at 94 percent. The same held true for Straight A hospitals, with 95 percent of the 358 Straight A hospitals part of health systems.
All 11 hospitals that have earned an A for every grading round since 2012 are affiliated with health systems.
The 10 health systems with the highest total number of A hospitals and Straight A hospitals in the fall 2025 report are:
- Nashville, Tennessee-based HCA Healthcare (51 A and 18 Straight A hospitals)
- Chicago-based CommonSpirit Health (49 A and 24 Straight A hospitals)
- Altamonte Springs, Florida-based AdventHealth (29 A and 21 Straight A hospitals)
- Oakland, California-based Kaiser Permanente (27 A and 12 Straight A hospitals)
- Charlotte, North Carolina-based AdvocateHealth (24 A hospitals and 1 Straight A hospital)
- Ontario, California-based Prime Healthcare Services (24 A and 11 Straight A hospitals)
- Falls Church, Virginia-based Defense Health Agency (18 A hospitals, and no Straight A hospitals due to the fact that military hospitals haven’t been eligible for a Safety grade for five rounds or more; they will become eligible in 2026)
- Brentwood, Tennessee-based Lifepoint Health (16 A and 2 Straight A hospitals)
- New York City-based Northwell Health (15 A and 3 Straight A hospitals)
- Sacramento-based Sutter Health (15 A and 3 Straight A hospitals)
Also according to the report, the top five states for the largest percentages of A hospitals are Utah, Virginia, New Jersey, Connecticut and North Carolina, respectively.
Connecticut ranked 4th in the percentage of A hospitals on the ranking.
Four states — Iowa, North Dakota, Vermont and Wyoming — have no A hospitals.
