Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome is the time from initiation of ADHD pharmacotherapy to the first documented treatment change. A treatment change is defined as either a documented switch to another ADHD medication or documented discontinuation of ADHD pharmacotherapy. The outcome is assessed retrospectively over each patient’s individual observation period, starting with the date of the first documented ADHD medication and ending with the date of the first documented treatment change or, if no treatment change was documented, with the last documented outpatient contact. Data are collected exclusively from existing routine clinical documentation, particularly from medical records and the clinical information system of LVR-Klinik Bonn. No additional examinations, surveys or patient contacts are performed. | — |
Secondary
| Measure | Time frame |
|---|---|
| Number of documented medication changes per patient during follow-up; documented reasons for treatment changes, including adverse effects, insufficient efficacy, patient preference and adherence/compliance problems; differences in treatment persistence and switching rates between medication classes and specific substances; associations of age at treatment initiation and sex with the risk of treatment change. | — |
