Abstract : This report summarizes trends for Clostridium difficile infection (CDI) among Military Health System (MHS) beneficiaries in calendar year (CY) 2015. The overall CDI incidence rate increased 29.5 from the weighted historic average incidence rate; however, the CDI rate showed normal variation when compared to historical rates in the overall MHS beneficiary population. Incidence rates were higher in health care regions with larger inpatient CDI reservoirs, which were estimated by the healthcare-associated infection (HAI) metrics of overall and admission prevalence. Overall prevalence rates were only slightly higher (1.0 ) than admission prevalence rates, which suggests that CDI importation is the driving force for inpatient exposure compared to other hospital exposures that lead to hospital-onset infection. The traditional risk factors for CDI (antibiotic use, ages 65 years and older, and hospitalization) continue to be important in the diagnostic evaluation of CDI. However, the majority of MHS CDI episodes were acquired in the community in beneficiaries aged 45 years and older. In addition, although most cases had an antibiotic prescribed in the 90 days before symptom onset, approximately 32 of beneficiaries did not have a history of antibiotic use.
