Improving Infection Prevention in Cardiac Surgery: A Quality Improvement Project on Antibiotic Prophylaxis.

Area of Science:

• Infectious Diseases
• Public Health
• Surgical Outcomes

Background:

• Health care-associated infections (HAIs), especially surgical site infections (SSIs), are a significant cause of patient morbidity and mortality.
• Cardiac surgery patients are particularly vulnerable to HAIs, which incur substantial financial costs and long-term patient harm.
• A high-volume cardiac surgery center observed an increase in postoperative infections despite existing prevention measures.

Purpose of the Study:

• To improve infection prevention strategies in a cardiac surgery setting.
• To enhance perioperative team knowledge regarding antibiotic resistance.
• To implement a targeted antibiotic protocol, including methicillin-resistant Staphylococcus aureus (MRSA) prophylaxis.

Main Methods:

• A two-year quality improvement project was undertaken.
• Educational interventions focused on antibiotic resistance trends.
• An updated antibiotic protocol with MRSA prophylaxis was implemented, supported by electronic medical record modifications.
• Data collection and analysis were performed to assess intervention impact.

Main Results:

• No statistically significant change in SSI rates was observed post-intervention (P = .81).
• The study suggests the low prevalence of MRSA at the center may have influenced the results.
• Continuous evaluation of infection prevention protocols is crucial.

Conclusions:

• The quality improvement project did not significantly reduce SSI rates in this specific cardiac surgery center.
• The findings emphasize the importance of adapting infection prevention strategies based on local epidemiology and continuous monitoring.
• Further research may be needed to explore alternative or adjunctive interventions for SSI prevention in cardiac surgery.
