Background:
Methicillin-resistant Staphylococcus aureus (MRSA) surgical site infections (SSIs) increase morbidity and mortality. We examined the impact of the MRSA bundle on SSIs.
Methods:
Data regarding the implementation of the MRSA bundle from 2007 to 2008 were obtained, including admission and discharge MRSA screenings, overall MRSA infections, and cardiac and orthopedic SSIs. Chi-square was used for all comparisons.
Results:
A significant decrease in MRSA transmission from a 5.8 to 3.0 per 1,000 bed-days (P < .05) was found after implementation of the MRSA bundle. Overall MRSA nosocomial infections decreased from 2.0 to 1.0 per 1,000 bed-days (P = .016). There was a statistically significant decrease in overall SSIs (P < .05), with a 65% decrease in orthopaedic MRSA SSIs and 1% decrease in cardiac MRSA SSIs.
Conclusion:
Our data demonstrate that successful implementation of the MRSA bundle significantly decreases MRSA transmission between patients, the overall number of nosocomial MRSA infections, and MRSA SSIs.
Insights
The Methicillin-resistant Staphylococcus aureus (MRSA) bundle significantly reduced MRSA transmission and nosocomial infections. This intervention led to a notable decrease in MRSA surgical site infections (SSIs).
Area of Science:
- Infectious Disease Epidemiology
- Healthcare-Associated Infections
- Antimicrobial Resistance
Background:
- Methicillin-resistant Staphylococcus aureus (MRSA) surgical site infections (SSIs) are a significant cause of patient morbidity and mortality.
- Effective strategies are needed to control the spread and impact of MRSA in healthcare settings.
Purpose of the Study:
- To evaluate the impact of implementing a comprehensive MRSA bundle on SSI rates.
- To assess the effectiveness of the MRSA bundle in reducing MRSA transmission and nosocomial infections.
Main Methods:
- Retrospective analysis of data from 2007-2008 on MRSA bundle implementation.
- Inclusion of MRSA screenings, overall MRSA infections, and cardiac/orthopedic SSIs.
- Statistical comparison using the chi-square test.
Main Results:
- MRSA transmission decreased significantly from 5.8 to 3.0 per 1,000 bed-days (P < .05).
- Overall MRSA nosocomial infections declined from 2.0 to 1.0 per 1,000 bed-days (P = .016).
- A significant reduction in overall SSIs was observed, including a 65% decrease in orthopedic MRSA SSIs.
Conclusions:
- Successful implementation of the MRSA bundle demonstrably decreases patient-to-patient MRSA transmission.
- The MRSA bundle effectively reduces the overall incidence of nosocomial MRSA infections.
- The intervention significantly lowers the occurrence of MRSA surgical site infections.
