Abstract : The EpiData Center (EDC) conducts routine surveillance of Escherichia coli among all beneficiaries seeking care within the Military Health System (MHS). This report describes activity in calendar year (CY) 2015.Health Level 7 (HL7)-formatted microbiology data identified E. coli infections, demographics, clinical characteristics, seasonal activity, and antibiotic resistance patterns. Infections were matched to HL7-formatted pharmacy data to assess prescription practices, the Standard Inpatient Data Record (SIDR) to determine healthcare-associated exposures, Defense Manpower Data Center (DMDC) rosters to determine burden among Department of Defense (DOD) active duty (AD) members, and the DMDC Contingency Tracking System (CTS) to determine Department of the Navy (DON) deployment-related infections. Overall, 2015 incidence rates (IRs) of E.coli in the MHS beneficiary and DOD active duty populations are increasing. Incidence among females was nearly 11 times higher than among males. The highest IR occurred outside the continental United States (OCONUS) (1,057.7 infections per 100,000 persons per year). Aligning with United States (US) trends, most infections were found in the urinary tract (96.2 ) and outpatient setting (97.7 ). Drug-resistant E. coli comprised 20.7 of all E. coli infections. Nitrofurantoin and ciprofloxacin were the most commonly prescribed antibiotics. DON deployment-related infections accounted for 0.2 of prevalence infections, the majority of which were females aged 18-24 years.
