About this study
The purpose of this study is to descriptively evaluate the persistence among adults treated with mirabegron or antimuscarinics in Australia, South Korea and Taiwan.
This study will also assess the persistence to the overall Overactive bladder (OAB) treatments of a patient, regardless of treatment discontinuation or switch to other OAB medications.
Read the detailed description
This study is entirely descriptive using secondary medical claim and pharmacy prescription data. No formal comparisons between users of mirabegron and antimuscarinic will be made. Furthermore, no a priori hypothesis testing is intended.

What is being measured
The primary outcome is the main question the study is designed to answer.
Patients persistence to the index medication
Persistence to the index medication (i.e. mirabegron; solifenacin; darifenacin; imidafenacin; tolterodine; oxybutynin; trospium; fesoterodine; propiverine) is defined as the time to discontinuation during the 1 year post-index period. Days with the index medication for each patient will be calculated as the sum of days of supply per prescription.
Measured: Up to 12 months
Secondary outcomes (1)
Patients persistence to the overall Overactive Bladder (OAB) treatment regardless of treatment switching to other OAB medications
Time to discontinuation of the overall OAB treatment during the one-year post-index period (persistence) is defined as days with the index medication (i.e. mirabegron; solifenacin; darifenacin; imidafenacin; tolterodine; oxybutynin; trospium; fesoterodine; propiverine) for each patient and days' supply of any OAB medication will be added up until the grace period exceeds 30 days.
Measured: Up to 12 months
