Abstract:
We present an approach to assessing the impact of surveillance for surgical site infections and providing feedback to surgeons on their progress, as part of continuous quality improvement. Adjusting for patient risk factors using the Standardized Mortality Ratio, there was a marked decrease over time in both SMR (1.3 to 0.27) and crude infection rates (32 to 10 per thousand operations per year). These declines cannot be explained by decreased length of hospital stay.
Insights
Implementing surgical site infection surveillance and surgeon feedback significantly reduced infection rates. Risk-adjusted analysis showed a substantial decrease in standardized mortality ratios and infection rates, demonstrating effective quality improvement.
Area of Science:
- Healthcare Quality Improvement
- Infectious Disease Surveillance
- Surgical Outcomes
Background:
- Surgical site infections (SSIs) pose a significant risk to patient safety.
- Effective surveillance and feedback mechanisms are crucial for reducing SSIs.
- Continuous quality improvement (CQI) initiatives are essential in surgical settings.
Purpose of the Study:
- To assess the impact of a surveillance program for surgical site infections.
- To evaluate the effectiveness of providing feedback to surgeons on their SSI rates.
- To demonstrate the utility of risk-adjusted metrics in quality improvement.
Main Methods:
- Implementing a surveillance system for surgical site infections.
- Utilizing the Standardized Mortality Ratio (SMR) to adjust for patient risk factors.
- Tracking crude infection rates and SMR over time.
Main Results:
- A significant decrease in SMR from 1.3 to 0.27 was observed.
- Crude surgical site infection rates declined from 32 to 10 per thousand operations annually.
- These improvements were sustained and not attributable to reduced hospital length of stay.
Conclusions:
- The developed approach effectively reduces surgical site infections.
- Surgeon feedback within a continuous quality improvement framework enhances patient safety.
- Risk-adjusted monitoring is vital for accurately assessing performance and driving improvements in surgical care.
