Pleasanton Hospital Drops to 'B' Safety Grade

Stanford Health Care Tri-Valley in Pleasanton received a “B” in the Leapfrog Group’s Spring 2026 Hospital Safety Grade, according to the watchdog’s May 6 release and the hospital’s current profile page. The same hospital had received an “A” in Leapfrog’s Fall 2025 grades, according to Leapfrog’s archived ratings and a local report published in November. Leapfrog assigns the grades twice a year to general hospitals based on measures tied to medical errors, injuries, accidents and infections. The Pleasanton grade change puts a local hospital into the middle tier of a closely watched national scorecard that hospitals often cite in public quality messaging. ### Which Pleasanton hospital was downgraded? Stanford Health Care Tri-Valley, at 5555 W. Las Positas Boulevard in Pleasanton, is the hospital listed with a “B” on Leapfrog’s Spring 2026 safety grade page. Leapfrog’s profile identifies the facility as a general hospital and notes that it completed the Leapfrog Hospital Survey. Patch reported on May 7 that Stanford Health Care Tri-Valley had moved down from an “A” in Fall 2025 to a “B” in the new grading cycle. (leapfroggroup.org) The report said the hospital scored “above average” in several categories, including some surgical outcomes and fall-prevention measures. ### What does Leapfrog say the grade measures? The Leapfrog Group said on May 6 that its Hospital Safety Grade is a biannual letter grade from “A” to “F” assigned to most general hospitals in the United States. (hospitalsafetygrade.org) The nonprofit said the grades are based on a hospital’s ability to protect patients from medical errors, accidents, injuries and infections. (patch.com) Leapfrog’s ratings page says the program focuses specifically on patient safety, rather than broader measures of hospital quality. The group also says hospitals can review methodology updates, timelines and archival reports through its public ratings and reports pages. ### How unusual was the move from an A to a B? Fall 2025 data showed Stanford Health Care Tri-Valley among 126 California hospitals that received an “A,” according to Patch’s Nov. 13 report on the earlier grade release. (leapfroggroup.org) Spring 2026 data now show the Pleasanton hospital at “B.” Nationally, Leapfrog said Spring 2026 grades showed improvement in 17 measures of errors and infections. (hospitalsafetygrade.org) The group did not say in its release that every hospital improved, and the Pleasanton hospital’s move from “A” to “B” came during that broader national update. ### Did the hospital say anything about safety performance? (patch.com) Stanford Health Care Tri-Valley says on its “Quality Matters” page that patient safety is a core value and that its strategic plan includes safety goals and metrics, including a goal of zero preventable harm. The page says the hospital aligns with nationally recognized quality and safety standards and publicly reports progress. (leapfroggroup.org) The publicly available sources reviewed for this article did not show a new statement from Stanford Health Care Tri-Valley specifically addressing the Spring 2026 downgrade.
