The EpiData Center conducts routine surveillance of clinically significant organisms within the Department of the Navy and the Department of Defense DOD beneficiary populations. For calendar year CY 2015, this report summarizes incidence, prevalence, demographic and clinical characteristics, prescription practices, and antibiotic resistance patterns observed for Acinetobacter species infections identified within the Military Health System MHS. Several data sources were linked to assess a variety of descriptive and clinical factors related to Acinetobacter species. Health Level 7 HL7 formatted microbiology data were used to identify infections. Infections were matched to HL7-formatted pharmacy data to assess prescription practices, the Standard Inpatient Data Record to determine healthcare-associated exposures, Defense Manpower Data Center DMDC rosters to determine burden among DOD active duty service members, and the DMDC Contingency Tracking System to determine deployment-related infections. In 2015, the Acinetobacter species incidence rate was 5.63 per 100,000 persons per year, which reflects a 10.91 increase from the weighted historic incidence rate. The majority of infections in 2015 were identified in the outpatient setting and manifested as skin and soft tissue and wound infections. Acinetobacter baumannii-calcoaceticus complex was the most common species isolated 29.3 . Overall incidence of multidrug-resistant Acinetobacter remains low in the DOD 0.3 per 100,000 persons per year. Overall, antibiotic susceptibilities remain high and relatively stable.
