Point prevalence surveys (PPS) are considered useful epidemiological surveys of healthcare-associated infections (HAIs) and antimicrobial use worldwide. However, Japanese PPS have not yet been reported mainly owing to medical staff shortages in the field of infectious diseases. The purpose of this pilot study was to evaluate the epidemiology of HAIs and antimicrobial use in a Japanese tertiary university hospital.
A one-day PPS was performed at Nagoya University Hospital (NUH) on July 3, 2014. Data on demographics, active HAIs, and antimicrobial use were collected using a data collection form.
Of 841 patients, 364 (43.3%) were more than 65 years of age, 199 (23.7%) were admitted for more than 31 days, 304 (36.1%) were administered at least one antimicrobial, and 384 (45.7%) received at least one medical device. Eighty-five patients had active HAIs (10.1%), and there were a total of 90 active HAI cases. A total of 118 antimicrobials were administered for treatment of 90 HAI cases . Among the 90 HAI cases, the most frequently diagnosed infection was pneumonia (20.0%), the most frequently administered antimicrobials were carbapenems (22.9%), and the most frequently isolated organisms belonged to the Enterobacteriaceae family (29.8%). Antimicrobials were administered for surgical prophylaxis in 119 cases; of these, 48 (40.3%) were administered orally.
The incidence of HAIs in NUH is higher than that in other developed countries. The social and medical situation in Japan may affect patient demography, active HAIs, and antimicrobial use. Multi-center PPS are necessary to reveal the real Japanese epidemiology of HAIs and antimicrobial use.
