Centers for Medicare & Medicaid Services · compared with hospitals nationwide
Mercy Tiffin Hospital was no different from the national benchmark on the one hospital-acquired infection CMS could compare. Its rate of serious complications was same as national.
Hospital-acquired infections
Serious complications
Death rates within 30 days
| Patients treated for | This hospital | U.S. |
|---|---|---|
| Heart failure patients | 9.7% | 11.1% |

| COPD patients | 9.3% | 8.6% |
| Hospital-wide, all conditions | 3.2% | 3.9% |
Risk-adjusted rates. CMS has not published a statistical better/worse comparison for these death rates in the current release, so small differences from the U.S. rate may be chance.
Other complications
None of the other safety indicators CMS compares was statistically better or worse than national.

"Better" or "worse" means CMS found the difference from the national benchmark statistically significant; most hospitals are "no different". Infection results compare the infections a hospital reported with the number predicted for a hospital of its size and type (a ratio below 1 means fewer than predicted), for Oct 2024 – Sep 2025. Death and complication rates are risk-adjusted for how sick patients were. Each death rate counts deaths within 30 days of a hospital stay, pooled over one to three years of Medicare patients depending on the measure. About the data.
