Infections in a coronary care unit.

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Epidemiology

Background:

• Nosocomial infections pose a significant threat in critical care settings.
• Coronary Care Units (CCUs) are high-risk environments for patient infections.
• Understanding infection epidemiology is crucial for improving patient outcomes.

Purpose of the Study:

• To analyze the rates, common pathogens, sites, and outcomes of infections in a CCU.
• To compare infection rates within the CCU to overall hospital-acquired infections.
• To provide data for benchmarking CCU infection rates in other institutions.

Main Methods:

• A 3-year retrospective analysis of all infections in CCU patients.
• Utilized standard surveillance methods and definitions from the Centers for Disease Control.
• Documented infection rates, causative agents, and patient outcomes.

Main Results:

• 236 infections were documented in 200 patients over 3 years.
• Overall CCU infection rate was 5%, with 2% being CCU-acquired.
• Lower respiratory and urinary tract infections were most common, often caused by E. coli, S. aureus, and Klebsiella-Enterobacter-Serratia.
• Mortality was 31% in infected patients versus 8-12% in uninfected patients.

Conclusions:

• CCU infections are prevalent and significantly increase patient mortality.
• Lower respiratory infections and bacteremias are associated with higher mortality rates.
• Findings provide valuable data for CCU infection control and benchmarking.
