Annual Surveillance Summary: Vancomycin-Resistant Enterococci (VRE) Infections in the Military Health System (MHS), 2017

Abstract

The EpiData Center (EDC) conducts routine surveillance of vancomycin-resistant enterococci (VRE) 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 VRE infections in the calendar year (CY) 2017. Multiple data sources were linked to assess descriptive and clinical factors related to VRE. Health Level 7 (HL7)-formatted Composite Health Care System (CHCS) microbiology data identified Enterococcus species infections resistant to vancomycin. 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. Overall, incidence rates (IRs) of VRE infections declined among MHS beneficiaries to 1.22 per 100,000 persons per year. A slight increase in incidence was observed among Navy beneficiaries; however, the IR was within the expected variance with only a 3.7 increase in incident infections. The United States (US) West and South Atlantic regions had the highest IRs, and healthcare-associated (HA) cases comprised the largest proportion of all infections identified (82.3 ). While the largest proportion of all prevalent infections were classified as community-onset (CO) (35.4 ), a substantial proportion was also identified as hospital-onset (HO) (28.5 ). Treatment for VRE infections among DOD beneficiaries primarily included daptomycin and linezolid, which remained effective through 2017. Current infection control practices appear effective, and continued surveillance is recommended.
