CDI Incidence in US Hospitals Among Age Groups

BMC Infect Dis; ePub 2016 Nov 17; Pechal, et al

Clostridum difficile infection (CDI) incidence, mortality, and hospital length of stay (LOS) in US hospitals were highest in the elderly adult population, a recent study found. The retrospective analysis of the US National Hospital Discharge Surveys from 2001 to 2010 included data representing 2.3 million hospital discharges for CDI over the study period. Patients were stratified by age: <18 years (pediatrics), 18 to 64 years (adults), and ≥65 years (elderly adults). Researchers found:

  • CDI incidence was highest among elderly adults (11.6 CDI discharges/1,000 total discharges), followed by adults, and pediatrics.
  • Higher rates of mortality were also highest among the elderly (8.8%), compared to adults (3.1%) and pediatrics (1.4%).
  • Median hospital LOS was highest in the elderly (8 days) compared to adults (7 days) and pediatrics (6 days).
