Top 50 hospitals by HAC scores
The Center for Medicare and Medicaid Services (CMS) launched the Hospital-Acquired Condition (HAC) Reduction Program to incentivize hospitals to take stronger precautionary measures to reduce the number of preventable illnesses and readmissions post-acute care.
HACs can lead to increased healthcare spending, a higher risk of patient deaths and readmissions, and longer lengths of stay.
CMS tracks 14 HACs across several categories, including surgical site infections (SSIs), bloodstream infections (BSIs), and pressure ulcers. However, the HAC Reduction Program takes only six of these into account:
- Clostridium difficile (C. Diff)
- Catheter-associated urinary tract infections (CAUTI)
- Central-line-associated bloodstream infections (CLABSI)
- Methicillin-resistant staphylococcus aureus (MRSA)
- Surgical site infections for colon surgeries and hysterectomies
Scores reflect hospital performance on HACs compared to the national mean. A negative domain score indicates a better performance since it reflects values below (or better than) the national mean.
This Healthcare Insight reviews hospital HAC Reduction Program scores tracked in the Definitive Healthcare HospitalView product. Results are based on 2021 data from the October 2022 update.

Which hospital has the best HAC score?
Mayhill Hospital in Denton, Texas has the lowest HAC Reduction Program score at -1.95. The next six hospitals each have a score of -1.73
Nine of the top 50 hospitals on the list are located in Texas, which is also the state with the highest number of total hospitals. Nearly two-thirds of the hospitals on the list (32) are in the southeast or the southwest U.S.
How are HAC scores calculated?
Since 2018, CMS used the winsorized z-score methodology to calculate HAC total score. With this process, the raw measure result of hospitals that fall below the 5th percentile and above the 95th percentile are set to the 5th and 95th percentile, respectively. This is done to reduce the impact of outliers in score calculations.
The scores displayed are determined by taking a hospital’s winsorized measure result, subtracting the mean of winsorized measure results, and then dividing that result by the standard deviation of winsorized measure results.
