Treatment Persistence Among Patients With Overactive Bladder: A Retrospective Secondary Data Analysis in Asia Oceania

Treatment Persistence Among Patients With Overactive Bladder: A Retrospective Secondary Data Analysis in Asia Oceania

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.

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.

Inclusion Criteria:

• Patient with a new prescription of the index medication within the index period;
• Patient received orally administered monotherapy for OAB on index date.

Exclusion Criteria:

• Patient with prior dispensing record of the index medication during the pre-index period;
• Patient received onabotulinumtoxin A and/or surgical intervention as part of the OAB treatment between the pre index and post-index period;
• Patient diagnosed with stress incontinence (International Classification of Diseases-10 (ICD-10) N39.3 or equivalent) or had dispensing record of medication for stress incontinence (duloxetine) before index date;
• Patient with urinary tract infection (ICD-10 N30.0 or equivalent) (for National Health Insurance Research Database (NHIRD) and Health Insurance Review and Assessment (HIRA) database) or a co-prescription of any antibiotics (for NostraData) on index date.
