Abstract

IMPORTANCE: There is strong evidence for long-term cognitive effects with anticholinergic use. Differences in insurance coverage of anticholinergics and beta-3 agonists hinder individualization of overactive bladder (OAB) treatment. OBJECTIVES: The aims of the study were to assess individual and family health insurance plan coverage for select OAB medications and to compare coverage of preferred medications to those with a greater risk of cognitive dysfunction. STUDY DESIGN: This cross-sectional study analyzed formularies for the top 7 U.S. medical insurers. Coverage tiers were assessed for the following 7 OAB medications: (1) oxybutynin instant-release 5 mg, (2) oxybutynin extended-release 5 mg, (3) solifenacin 5 mg, (4) trospium instant-release 20 mg, (5) trospium extended-release 60 mg, (6) mirabegron 25 mg, and (7) vibegron 75 mg. Coverage was compared between nonpreferred (oxybutynin, solifenacin) and preferred medications (trospium, mirabegron, vibegron). Coverage scores, representing a weighted average based on coverage tier frequency relative to the number of plans investigated for each state or insurer, were generated with a lower coverage score indicating better coverage (range, 0.2-1.0). RESULTS: A total of 2,780 insurance plans from 41 states representing a 47% market share for the individual and family marketplace were evaluated. Oxybutynin IR had the best coverage score across insurers (0.2) while vibegron had the worst (0.92). Preferred medications were more…
