Annual Surveillance Summary: Escherichia coli (E. coli) Infections in the Military Health System (MHS), 2016
Abstract
The EpiData Center Department (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 E. coli in calendar year (CY) 2016. 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, Defense Manpower Data Center (DMDC) rosters to determine burden among Department of Defense (DOD) active duty (AD) service members, and the DMDC Contingency Tracking System (CTS) to determine Department of the Navy (DON) deployment-related infections. The E. coli incidence rate among MHS beneficiaries demonstrated a minimal increase of 3.1 during 2016 (676.7 per 100,000 persons) in relation to the weighted historic incidence rate (656.2 per 100,000 persons per year). Characteristics of E. coli infections are concurrent 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 21 of all prevalent E. coli infections during 2016 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.
