Persistence and Adherence of Anticholinergics and Beta-3 Agonist for the Treatment of Overactive Bladder: Systematic Review and Meta-Analysis, and Network Meta-Analysis

Purpose: We aimed to investigate the persistence and adherence rate of over-active bladder medications and factors that affect these rates. Materials and Methods: We conducted electronic English-language literature searches of the PubMed (R), Cochrane Library, and EMBASE (R) databases from the earliest available date of indexing through May 21, 2019 using the Medical Subject Headings (MeSH) terms and EMBASE subject headings (Emtree). Primary measurement outcomes were overall persistence and adherence rate at 6, 12, 24, and 36 months in anticholinergics and mirabegron. Secondary outcomes were individual effect of each medication on persistence and adherence rate at 12 months, and moderating factors affecting the overall persistence and adherence rate at 12 months. Results: Pooled overall persistence rate at 12 months of overactive bladder medications of anticholinergics and mirabegron was 0.218 (95% CI: 0.197-0.240). The pooled overall persistence rate at 12 months was 0.402 (95% CI: 0.277-0.528) in mirabegron, 0.249 (95% CI: 0.182-0.316) in solifenacin, and 0.220 (95% CI: 0.078-0.361) in fesoterodine. Overall adherence rate of overactive bladder medications of anticholinergics and mirabegron was 0.589 (95% CI: 0.507-0.670). The pooled overall adherence rate at 12 months was 0.654 (95% CI: 0.528-0.781) in mirabegron, 0.784 (95% CI: 0.588-0.980) in solifenacin, 0.782 (95% CI: 0.652-0.911) in fesoterodine, and 0.679 (95% CI: 0.651-0.707) in imidafenacin. Persistence and adherence rates were associated with age, gender, anticholinergic exposure history, type of medication, study type, and study year. Conclusions: Persistence and adherence rates were lower than previously reported and were associated with certain clinical and demographic factors.

Automated summary

The study investigated the persistence and adherence rates of overactive bladder medications, finding that these rates were lower than previously reported and were associated with factors such as age, gender, and type of medication.
