Abstract:
Clostridium difficile infection (CDI) is associated with increased cost, morbidity, and mortality in postoperative patients. Variable rates of postoperative CDI are reported among 4 surgical specialties during the 30-month study period. Risk factors for CDI include antibiotic use, increased ASA score, and increased admissions in the past year. Infect Control Hosp Epidemiol 2017;38:1254-1257.
Insights
Postoperative Clostridium difficile infection (CDI) presents significant risks. Key risk factors for developing CDI after surgery include prior antibiotic exposure and higher American Society of Anesthesiologists (ASA) scores.
Area of Science:
- Infectious Diseases
- Surgical Outcomes
- Healthcare Epidemiology
Background:
- Clostridium difficile infection (CDI) significantly increases costs, morbidity, and mortality in patients undergoing surgery.
- Postoperative CDI rates vary considerably across different surgical specialties.
Purpose of the Study:
- To analyze the incidence and risk factors of postoperative Clostridium difficile infection (CDI) within a surgical patient population.
- To identify specific patient characteristics and exposures associated with an increased risk of CDI following surgical procedures.
Main Methods:
- Retrospective analysis of postoperative patients over a 30-month period.
- Data collection included patient demographics, surgical specialty, antibiotic use, prior hospital admissions, and American Society of Anesthesiologists (ASA) scores.
- Statistical methods were employed to identify risk factors for CDI development.
Main Results:
- Variable rates of postoperative CDI were observed across four surgical specialties.
- Significant risk factors identified for CDI included prior antibiotic use, a higher ASA score, and multiple hospital admissions in the preceding year.
Conclusions:
- Postoperative CDI is a critical concern with identifiable risk factors.
- Targeted interventions focusing on antibiotic stewardship and patient risk stratification may help mitigate CDI incidence in surgical settings.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
