Abstract

Abstract: Purpose: Few medical treatment options exist for detrusor underactivity or urinary retention in women. Bethanechol, a cholinergic agonist, may improve detrusor contractility in these conditions; however, its clinical efficacy is limited. We sought to examine the patterns of Bethanechol use by physicians in an ambulatory care setting using a national database to determine if it is still prescribed for patients with bladder dysfunction. Materials and Methods: The National Ambulatory Medical Care Survey (NAMCS) database was queried for a sample of patient visits to office‐based physicians from 2003‐2013. Visits were included for women aged 18 years or older with diagnosed lower urinary tract symptoms (LUTS), neurogenic bladder, or urinary retention based on ICD‐9‐CM codes. Visits in which Bethanechol was prescribed were analysed with descriptive statistics. Sampling weights were adjusted for nonresponders to yield an unbiased national estimate of ambulatory care visits. Results: Out of a weighted sample of 17 321 630 included patient visits, 132 281 (0.8%) visits included a prescription for Bethanechol. Patients prescribed Bethanechol had a mean age of 62.3 ± 2.1 and were predominantly Caucasian (67%) followed by African American (18%). The primary diagnosis associated with Bethanechol was atony of bladder (35%), urinary retention (20%), neurogenic bladder (18%), urinary incontinence (16%), and incomplete bladder emptying (10%). Visits were primarily for chronic conditions (63%). It was typically prescribed as a continued medication (79%) most often by urologists (92%) followed by internal medicine clinicians (8%). Conclusions: Bethanechol continues to be prescribed in elderly women primarily for detrusor atony, urinary retention, or incomplete bladder emptying.
