Background : Anticholinergic drugs (ACDs) are used for treating various clinical conditions of the elderly. However, caution is needed due to their several central and peripheral adverse effects including urinary retention (UR). UR can extend hospitalization period and increase the burden of polypharmacy due to ureter catheter insertion or additional drug therapy. The aim of this study was to analyze current status of ACD-induced UR and risk factors in older patients.
Methods :The study retrospectively reviewed patients aged 65 years and older who were first prescribed oral ACDs from July to September 2020. We measured anticholinergic burden using Korean Anticholinergic Burden Scale (KABS) and total number of ACDs. We also analyzed risk factors associated with UR.Results : Of a total of 1,883 patients, 115 (6.1%) patients developed UR. In the UR group, the KABS and total number of ACDs were significantly
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
