Leastfrog's new biannual report, the only national ratings program focused on patient safety, ranks Massachusetts 16th among all states for the percentage of hospitals receiving "A" grades in spring 2026. The report found significant improvement in 17 measures, including health care-associated infections, medication safety systems, and patient experience. After peaking in fall 2022, several health-related infections decreased sharply, including central line-associated bloodstream infections, catheter-associated urinary tract infections, and serious intestinal infections linked to antibiotic use. The study also found significant gains in medication safety, with use of computerized physician order entry systems rising from 66% of hospitals meeting Leapfrog standards in 2018 to 90% in 2025. However, about 450 hospitals were not assigned grades after a federal court ruling involving several facilities that did not participate in the survey.
