ABSTRACT
Background: The global point prevalence survey (Global-PPS) is the standard for the surveillance of prescribed antimicrobials among inpatients and provides data for the development of hospital antimicrobial stewardship programs. Aim: To evaluate the prevalence and quality of antimicrobial prescriptions using the universally standardized Global-PPS protocol in a non-acute care hospital in Saitama Prefecture, Japan. Methods: Antimicrobial prescriptions for inpatients, staying at the hospital overnight, were surveyed on three separate week days in November 2018, January 2019, and May 2019. Information on the prescribed antimicrobials on the survey target day was obtained from the in-hospital pharmacy. Survey data were collected by physicians, based on the extracted information. Patient information was anonymized and entered in the Global-PPS Web application by physicians. We report the antimicrobial use prevalence, the indication for prescription, diagnosis, the most prescribed antimicrobials, and a set of quality indicators related to antimicrobial prescribing. Results: In total, 6.7% of the surveyed inpatients (120/1796) were prescribed antimicrobials on the survey day. Sulfamethoxazole/trimethoprim was the most commonly prescribed, with 20.0% of systemic antibiotic prescriptions (ATC J01). Of all antibiotics for systemic use, up to 58.4% were Watch antibiotics, as defined by the World Health Organization AWaRe classification. The most prescribed group of systemic antibiotics was non-penicillin beta-lactam antibiotics (34.4%), followed by penicillin antibiotics in combination with beta-lactamase inhibitors (25.6%), and sulfonamides with trimethoprim (20.8%). Healthcare-associated infections and medical prophylaxis were the most common indications reported in 69.3% and 26.3% of prescriptions, respectively. The most common diagnosis for systemic antibiotic prescriptions was pneumonia (49.6%). Reasons for antimicrobial prescriptions were indicated in the medical records for 67.1% of prescriptions, and the stop/review date was documented to be 50.3%. Compliance with local guidelines reached 66.7%. Conclusions: This study highlights important challenges related to antimicrobial prescription in a highly specific, non-acute care patient population.
