Annual Surveillance Summary: Escherichia coli (E. coli) Infections in the Military Health System (MHS), 2017
Abstract
The EpiData Center (EDC) conducts routine surveillance of Escherichia coli (E. coli) incidence and prevalence among all beneficiaries seeking care within the Military Health System (MHS). This report describes demographics, clinical characteristics, prescription practices, and antibiotic resistance patterns observed for Escherichia coli in the calendar year (CY) 2017. Multiple data sources were linked to assess descriptive and clinical factors related to E. coli. Health Level 7 (HL7)-formatted Composite Health Care System (CHCS) microbiology data identified E. coli infections. These infections were matched to HL7-formatted CHCS pharmacy data to assess prescription practices, the Standard Inpatient Data Record (SIDR) to determine healthcare-associated exposures, and the Defense Manpower Data Center (DMDC) rosters to determine burden among Department of Defense (DOD) active duty (AD) service members. The E. coli incidence rate among MHS beneficiaries decreased by 7.0% during 2017 in relation to the weighted historic incidence rate (634.9 vs. 682.6 per 100,000 persons per year). Characteristics of MHS E. coli infections concur with existing literature, and occurred at higher rates among females, manifested most commonly as urinary tract infections (UTIs), and primarily identified as community-associated (CA) cases. Approximately 20% of all prevalent E. coli infections during 2017 were multidrug resistant, underscoring the need for continued surveillance. While antibiotic susceptibilities indicate that viable treatment options are available for E. coli infections in the MHS, some commonly prescribed antibiotics no longer display sufficient efficacy or are no longer recommended for treating select conditions. Further surveillance and analysis are warranted.
