Abstract

Objectives: First-line treatment for patients with neurogenic detrusor overactivity (NDO) is anticholinergic or beta-3 agonist medication. The addition of a secondary medication in patients with NDO may avoid progression to third- and fourth-line therapies. We aim to identify patterns of medication use for patients with neurogenic lower urinary tract dysfunction (NLUTD) using a national database. Methods: The National Ambulatory Medical Care Survey (NAMCS) database was queried for a sample of ambulatory patient visits from 2003 to 2015. Outpatient visits were included for all patients aged 18 years or older diagnosed with NLUTD. Dual therapy was defined as prescription of two anticholinergics or one anticholinergic + beta-3 agonist on the same visit. Visits in which medications were prescribed were analyzed with descriptive statistics. Results: Out of a weighted sample of 5 391 680 patient visits with a primary diagnosis of NLUTD, 1 602 705 (30%) were prescribed medical therapy. Of included patients prescribed NDO medications, the majority were white (80%), located in the Northeast (71%), and of a mean age of 51 ± 3. Of these patients, at least 93% of patients were prescribed anticholinergics, and 37% were prescribed dual therapy. Patients 65 years and older were more likely to initiate a new NDO medication at their visit (43%) than patients under 65 (7%). Conclusions: This is the first study to analyze the use of medical therapy for NLUTD in a large outpatient setting. Further prospective evaluation of patient satisfaction and efficacy of both single anticholinergic medication and dual therapy is needed.
