Outcomes of Community & Hospital-Onset CDI

Clin Infect Dis; ePub 2018 Aug 23; Pinzon, et al

Community-onset (CO) accounts for a significant proportion of Clostridium difficile infections (CDI) in the Veterans Health Administration (VHA) system and is more common than hospital-onset CDI, a recent study found. The retrospective cohort study included all patients with a positive test for C. difficile within VHA Corporate Data Warehouse (CDW) between January 1, 2011 and December 31, 2014. Researchers found:

  • 19,270 episodes of CDI were identified, involving 15,972 unique patients (95% male, 44% had a HCF onset, 42% were CO).
  • 31% of cases were non-severe, 40% were severe, and 21% were fulminant.
  • Overall, 40% of patients received antibiotics in the 90 days before CDI (44% in HCF vs 36% in CO).
  • Recurrence was noted for 18.2% of all cases; 30-day all-cause mortality was 9.2%.
