| Outcome in surgical patients | Amount by which rates are lower for: | |
|---|---|---|
| High RN staffing | High staffing, all levels (RNs, LPNs, aides) | |
| Urinary tract infection | 5-6% | 3-14% |
| Failure to rescue | 4-6% | 2-12% |
| Hospital-acquired pneumonia | 11% | 19% |
|
Note: Difference is expressed as a range of values (e.g., 2-12 percent) because several statistical models were used in evaluating the relationship between nurse staffing levels and each adverse event. |
