Staphylococcus epidermidis sepsis in surgical patients

Area of Science:

• Infectious Diseases
• Surgical Infections
• Microbiology

Background:

• Staphylococcus epidermidis is a common cause of healthcare-associated infections.
• Identifying risk factors and outcomes for S. epidermidis sepsis in surgical patients is crucial.

Purpose of the Study:

• To determine factors associated with risk, mortality, and invasive sepsis in surgical patients with S. epidermidis bloodstream infections.
• To evaluate the impact of appropriate antibiotic therapy on mortality.

Main Methods:

• Retrospective analysis of 58 surgical patients with two or more positive blood cultures for S. epidermidis.
• Assessment of clinical data, including operations, nutritional support, antibiotic regimens, and patient demographics.

Main Results:

• Gastrointestinal operations, total parenteral nutrition, and multiple antibiotics were associated with bacterial sepsis.
• Mortality was 46% and increased with age >50, GI operations, other gram-positive sepsis, recurrent sepsis, and antibiotic resistance.
• Appropriate antibiotic therapy for >50% of S. epidermidis isolates significantly reduced mortality.

Conclusions:

• Staphylococcus epidermidis is a significant pathogen in critically ill surgical patients.
• Invasive S. epidermidis sepsis requires specific antibiotic therapy.
• Early recognition and targeted treatment are key to improving outcomes.
