Objectives To determine the proportion of nursing home (NH) residents (NHR) with overactive bladder (OAB) or urinary incontinence (UI) with potential pharmacodynamic contraindications to antimuscarinic treatment because of concomitant anticholinergic medications or acetylcholinesterase inhibitors (AChEIs) and nonpharmacological limitations to antimuscarinic treatment. Design Cross‐sectional retrospective analysis. Setting U.S. skilled nursing facilities. Participants Nursing home residents with a diagnosis of OAB or UI. Measurements Linked and deidentified pharmacy claims and Minimum Data Set (MDS) 3.0 records (October 1, 2010 to September 30, 2012). Results Of NHRs, 71.3% received at least one anticholinergic medication. Medications that can cause or worsen UI were used commonly. AChEIs and antimuscarinic treatment were prescribed concurrently in 24% of NHRs with OAB or UI. NHRs with OAB or UI were more likely to have concurrent moderate to severe cognitive impairment (MSCI) (70.1%) than those without (29.9%) (P < .001). NHRs with or without OAB or UI and with MSCI were more likely to be treated with an anticholinergic medication than those without MSCI (P = .001). When NHRs with MSCI, severe mobility impairment (SMI), and anticholinergic medication and AChEI use were excluded, only a small proportion of NHRs were potential candidates for antimuscarinic treatment (6.6% with OAB or UI, 6.2% with UI). Conclusions This study advances understanding of the challenges in prescribing antimuscarinic treatment safely and appropriately in elderly NHRs with a high prevalence of drug interactions, underlying MSCI, and SMI.
