3 CT Hospitals Earn Either 'D' Or 'C' Grade In New Safety Ranking: Here Is The Full List

A new hospital safety report released Wednesday shows that 18 hospitals in Connecticut earned “A” grades and three earned either a "C" or a "D" for their ability to protect patients from often preventable harm.

The Leapfrog Group’s Spring 2026 Hospital Safety Grades are a biannual ranking that assigns “A,” “B,” “C,” “D” or “F” letter grades to all general hospitals in the United States based on their ability to protect patients from medical errors, accidents, injuries and infections.

“A” hospitals in Connecticut are:

• Bridgeport Hospital
• Bridgeport Hospital Milford Campus
• Charlotte Hungerford Hospital
• Danbury Hospital
• Greenwich Hospital
• Griffin Hospital
• Hartford Hospital
• Johnson Memorial Hospital
• Middlesex Hospital
• MidState Medical Center
• Sharon Hospital
• Stamford Health
• St. Vincent's Medical Center
• The William W. Backus Hospital
• University of Connecticut Health Center, John Dempsey Hospital
• Windham Community Memorial Hospital
• Yale New Haven Hospital - Saint Raphael Campus
• Yale New Haven Hospital

“B” hospitals are:

• Lawrence & Memorial Hospital
• Manchester Memorial Hospital
• New Milford Hospital
• Norwalk Hospital
• Saint Mary's Hospital
• The Hospital of Central Connecticut

"D" and "C" hospitals are:

CT is No. 1

Connecticut ranks first among all states for the percentage of hospitals receiving “A” grades in the spring 2026 report card at 64.3%.

Yale New Haven Hospital, one of the hospitals that received an "A" grade, performed better than average across multiple categories, including practices to prevent errors and reduce surgical complications.

“Earning top safety grades across our health system reflects a deep and sustained commitment to protecting our patients from harm,” said Christopher O’Connor, CEO, Yale New Haven Health. “Safety is not a program at our hospitals – it is a foundational value that guides everyday actions.”

Leapfrog said its biannual report — the only national ratings program focused exclusively on patient safety — shows improvement in 17 measures, including health care-associated infections, medication safety systems and patient experience.

“The good news is that hospitals across the country are making meaningful strides in patient safety and helping save countless lives,” Leah Binder, the group’s president and CEO, said in a news release.

After peaking in fall 2022, several health care-associated infections declined sharply, according to the report. Central line-associated bloodstream infections fell by half; catheter-associated urinary tract infections dropped 45 percent; methicillin-resistant Staphylococcus aureus infections declined 42 percent; and serious intestinal infections linked to antibiotic use went down 30 percent.

The report also found gains in medication safety. Use of computerized physician order entry systems, which can flag prescribing errors, rose from 66 percent of hospitals meeting Leapfrog standards in 2018 to 90 percent in 2025. Adoption of barcode medication administration systems increased from 47 percent to 93 percent over the same period.

Patient experience scores, measured through Medicare and other federal surveys, have improved since hitting a low in fall 2023, rising by about one point on average across five safety-related measures, including communication with nurses and doctors and responsiveness of hospital staff.

Among states, Connecticut, Virginia and South Carolina had the highest share of A-rated hospitals, followed by Utah, Montana, New Jersey, Florida, Maryland, North Carolina and California. Montana and Maryland entered the top 10 for the first time, while Florida rose from 15th place in fall 2025 to seventh. No hospitals in North Dakota, South Dakota, Vermont or Wyoming received an A grade.

About 450 hospitals were not assigned grades after a federal court ruling in South Florida involving several facilities that did not participate in Leapfrog’s 2024 or 2025 survey. The group said it applied the change nationwide and is appealing the decision while reviewing its methodology.
