CMS tracks six HAI measures including central line infections, catheter-related urinary tract infections, surgical site infections, and C. difficile rates. This facility has 6 HAI measures performing better than the national benchmark.
This represents strong infection control performance. Facilities that consistently outperform HAI benchmarks typically maintain rigorous hand hygiene protocols, antimicrobial stewardship programs, and environmental disinfection standards.

About Our Scoring Methodology
Our SafeHospitals USA Safety Score is calculated from the official CMS Hospital Compare dataset using a weighted composite of: hospital-acquired infection rates (HAI, 30% weight), patient safety indicator measures (25%), mortality measure outcomes (20%), 30-day readmission rates (15%), and patient experience survey scores (10%). Scores range from 0–10 and are normalized against the national distribution of all Medicare-certified facilities.
Scores are recalculated annually when CMS releases updated Hospital Compare data. The current scores reflect the 2024 CMS data release, last verified by our data team on March 15, 2026.
