Annual Surveillance Summary: Pseudomonas aeruginosa Infections in the Military Health System (MHS), 2017

Abstract

The EpiData Center (EDC) conducts routine surveillance of Pseudomonas aeruginosa 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 P. aeruginosa infections in the calendar year (CY) 2017. Multiple data sources were linked to assess descriptive and clinical factors related to P. aeruginosa. Health Level 7 (HL7)-formatted Composite Health Care System (CHCS) microbiology data identified P. aeruginosa 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. Overall, incidence rates (IRs) of P. aeruginosa infections in the MHS beneficiary and DOD AD populations are decreasing. The incidence of P. aeruginosa in the MHS decreased in 2017 compared to the historical average. The majority of infections occurred in those over 65 years of age. Similar to 2016, 47.9 of all prevalent P. aeruginosa infections were found to be healthcare-associated. A growing concern both in and outside of the hospital setting is the rise of multidrug-resistant (MDR) P. aeruginosa infections. P. aeruginosa infections did not display 100 susceptibility to any antibiotics in 2017. There was a statistically significant increase in gentamicin susceptibility, while a significant decrease in susceptibility was identified in ceftazidime. Findings suggest that fluoroquinolones are being used as the first line of defense, but are likely followed by piperacillin and cephalosporins due to their greater efficacy.
