What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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)
  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
