A Point Prevalence Study of Antimicrobial Use and Practice Among Nursing Homes in Singapore

摘要

BackgroundInappropriate antimicrobial use is a major cause for the development of antimicrobial resistance in nursing homes (NHs); however, little is known about antimicrobial use at NHs in Singapore compared with NHs in other countries.ObjectivesThe aim of this study was to determine the prevalence, practice and challenges of antimicrobial prescribing in Singapore NHs compared with those in other countries.MethodsA point prevalence survey (PPS) was conducted from August to October 2017. Data on antimicrobial use and the quality of documentation were retrieved from medical and/or medication records of NH residents. Informed consent was obtained from the NH management.ResultsNine of 73 NHs in Singapore, with a total of 1760 residents, participated in the PPS. The prevalence of oral antibiotic and topical antimicrobial use was 2% and 11%, respectively, and the worldwide point prevalence of antimicrobial prescribing in NHs ranged from 1-17% (median 8%). The key challenges identified locally were different from thoseof overseas NHs, including incomplete documentation of antimicrobial duration and indication of use, as well as the high prevalence of topical antimicrobial use.ConclusionsThe prevalence of oral antibiotic use in NHs in Singapore was lower, while topical antimicrobial use was higher, compared with NHs in other countries. Variability in antimicrobial prescribing and challenges in practice among local and overseas NHs implied that a comprehensive PPS could be beneficial to aid in the design of effective and practicable antimicrobial stewardship strategies appropriate for the NH.
