Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Participant reported success is measured using the Patient Global Impression of Improvement – Index (PGI-I) at 15 months post randomisation (approximately 12 months post treatment). 2. Economic outcome is the incremental cost per quality adjusted life year (QALY) gained of Urodynamics and comprehensive clinical assessment compared to comprehensive clinical assessment only, modelled over the lifetime of the patients | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Proportion of women receiving invasive treatment is measured by review of the clinical health records at 6 and 15 months post randomisation 2. Participant reported outcomes at 3, 6 and 15 months post randomisation which includes: 2.1. OAB symptoms measured by the ICIQ-OAB and UPS 2.2. Urgency and UUI episodes measured using the bladder diary 2.3. Other urinary symptoms measured using the 3 domains of the ICIQ-FLUTS (filling, voiding and incontinence) and the bladder Diary 2.4. Generic health related QoL status measured using general (EQ-5D-5L) and condition specific (ICIQ-LUTSqol) QoL assessment tools 3. Adverse Events is measured by review of the clinical health records at 6 and 15 months post randomisation 4. Qualitative study outcomes which includes: 4.1. Participants’ attitudes to invasive testing and expected outcomes (prior to randomisation or knowing their allocated study group) at baseline 4.2. Participants’ attitudes to potential treatment options (prior to randomisation or knowing their allocated study group) at baseline 4.3. Participants’ experience of Urodynamics and opinions regarding treatment outcome to include evaluation of treatment satisfaction or desire for further treatment (3 to 6 months post treatment) 4.4. Surgeon attitudes to the influence of Urodynamics on decision making at start of the study and 6 to 12 months after starting recruitment at their sites 5. Secondary economic outcomes which includes: 5.1. Incremental cost per QALY gained of Urodynamics and comprehensive clinical assessment compared to comprehensive clinical assessment only up to 15 months 5.2. Incremental cost per QALY gained of BoNT-A vs SNM as the initial treatment for refractory OAB over the lifetime of patients 5.3. Incremental cost per QALY gained of SNM test and BoNT-A treatment according to clinical assessment only compared to treatment guided by Urodynamics over the lifetime of patients 5.4.
