A bundled approach to reduce methicillin-resistant Staphylococcus aureus infections in a system of community...

Area of Science:

• Infectious Diseases
• Healthcare Epidemiology
• Public Health

Background:

• Methicillin-resistant Staphylococcus aureus (MRSA) presents a major threat to patient safety in U.S. healthcare settings.
• Limited research exists on effective MRSA infection reduction strategies in community hospitals.
• A need exists for evidence-based interventions to enhance patient safety and control MRSA spread.

Purpose of the Study:

• To assess the effectiveness of a multifaceted MRSA infection prevention program in community hospitals.
• To evaluate the impact of a bundled intervention on MRSA infection rates and patient safety.
• To determine the feasibility of implementing a comprehensive MRSA control strategy across diverse healthcare facilities.

Main Methods:

• A program incorporating active surveillance, enhanced barrier precautions, hand hygiene, disinfection, and leadership engagement was implemented in 159 acute care facilities.
• The intervention was deployed in 1Q-2Q 2007, with postintervention data collected from 3Q 2007-2Q 2008 and follow-up through 4Q 2009.
• Key metrics included MRSA nasal colonization rates, use of personal protective equipment and hand hygiene products, and healthcare-associated infection rates.

Main Results:

• Postintervention, 10.2% of high-risk patients had MRSA nasal colonization.
• Significant increases in disposable gown and alcohol-based hand sanitizer use were observed.
• Healthcare-associated central line-associated bloodstream infections and ventilator-associated pneumonia due to MRSA decreased by 39% (p < .001) and 54% (p < .001), respectively.
• Sustained reductions in infection rates were noted throughout the follow-up period.

Conclusions:

• A bundled, multifaceted approach can effectively reduce healthcare-associated MRSA infections in community hospitals.
• Translating scientific evidence into actionable clinical and executive expectations aids in overcoming implementation barriers.
• This study demonstrates the possibility of widespread, sustained MRSA infection reduction through a coordinated, evidence-based strategy.
