Insights

An increase in Clostridium difficile infection (CDI) cases in pediatric oncology patients was linked to specific hospital wards and antibiotic use. Enhanced infection control measures helped reduce CDI rates.

Area of Science:

  • Infectious Diseases
  • Pediatric Oncology
  • Hospital Epidemiology

Background:

  • Investigated a rise in Clostridium difficile infection (CDI) cases within a pediatric oncology patient population.
  • Observed an increase in hospital-onset CDI during the summer of 2012.

Purpose of the Study:

  • Identify risk factors associated with CDI in pediatric oncology patients.
  • Assess infection prevention and antimicrobial prescribing practices.
  • Understand transmission dynamics of CDI.

Main Methods:

  • Conducted a case-control study for CDI risk factor identification.
  • Evaluated infection prevention strategies and antimicrobial use.
  • Performed environmental sampling and pulsed-field gel electrophoresis for isolate strain-typing.

Main Results:

  • Hospitalization in the bone marrow transplant ward and exposure to CT scans or cefepime were independent CDI risk factors.
  • Increased cefepime use correlated with a practice change for neutropenic fever.
  • Enhanced infection prevention, including cleaning and isolation, led to decreased CDI rates.

Conclusions:

  • Strain diversity suggests complex transmission modes requiring further investigation.
  • Need for strategies to reduce patient susceptibility to CDI.
  • Further research on cefepime's role in CDI and its use for neutropenic fever is warranted.
