Recurrent Clostridium difficile infection in intensive care unit patients

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Epidemiology

Background:

• Clostridium difficile infection (CDI) poses a significant health threat, particularly in hospital settings.
• Recurrent CDI (rCDI) presents a challenge in patient management and increases healthcare burden.
• Understanding risk factors for rCDI in intensive care unit (ICU) patients is crucial for targeted interventions.

Purpose of the Study:

• To determine the 12-week cumulative incidence of recurrent Clostridium difficile infection (rCDI).
• To identify significant risk factors associated with rCDI in patients who acquired their initial CDI within an ICU.

Main Methods:

• A retrospective, single-center cohort study was conducted.
• Adult patients who developed CDI in 6 different ICUs between February 2010 and September 2013 were reviewed.
• Multivariable logistic regression analysis was employed to identify risk factors.

Main Results:

• Out of 162 ICU patients, 34 experienced rCDI, with a higher incidence in the ICU group (21%) compared to the non-ICU group (17%).
• The surgical intensive care unit (SICU) showed the highest incidence of rCDI at 43.8%.
• Significant risk factors for rCDI included prior CDI, longer ICU length of stay, acquisition in MICU or SICU, and chronic obstructive pulmonary disease (COPD).

Conclusions:

• Adult patients in ICUs face a significantly elevated risk of 12-week rCDI compared to non-ICU patients.
• Acquisition of CDI within an ICU is linked to increased rCDI risk.
• Identified risk factors for rCDI in ICU-acquired CDI patients are MICU/SICU location, prior CDI history, COPD, and extended ICU stay duration.
