The EpiData Center EDC conducts routine surveillance of Klebsiella species 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 Klebsiella species infections in calendar year CY 2017. Multiple data sources were linked to assess descriptive and clinical factors related to Klebsiella species. Health Level 7 HL7-formatted Composite Health Care System CHCS microbiology data identified Klebsiella species 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 Klebsiella species infections in the MHS beneficiary and DOD AD populations decreased in 2017. The annual Klebsiella species IR decreased by 4.9 compared to the weighted historic IR this decrease was within expected variation of Klebsiella species infections in the MHS population. Fluoroquinolones present better treatment options compared to nitrofurans based on susceptibility analysis. Nitrofurans, despite being one of the most frequently prescribed classes of drugs 34.2 of all prescriptions for Klebsiella infections, presented lowest efficacy 46.6 . Therefore, the current use of nitrofurantoin as a treatment option for Klebsiella species infections within the MHS population warrants further investigation. Current infection control practices appear effective and continued surveillance is recommended.
