Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Decision aid randomisation: Proportion of patients consenting to the treatment randomisation Treatment randomisation: Feasibility of randomisation in terms of average accrual rate per centre during the last 6 months of recruitment. | — |
Secondary
| Measure | Time frame |
|---|---|
| Decision aid randomisation: Decisional quality post-treatment Treatment randomisation: 1. Compliance with allocated treatment 2. Clinical failure. Duration of follow-up: 10 years 3. PSA relapse. Duration of follow-up: 10 years 4. Patient-reported quality of life at 5 years (see below for details) 5. Toxicity. Duration of follow-up: 10 years Quality of life will be measured using a 50-question document to include the following: a. The 12-item short form health survey (SF-12; General quality of life) b. European Quality of Life questionnaires (EQ-5D; General quality of life to tie in with health economic data) c. The International Continence Society 'male short-form' (ICSmaleSF) questionnaire (urinary functioning) d. Vaizey Questionnaire (A short, validated bowel function questionnaire) e. The International Index of Erectile Function (IIEF5) The questionnaires will be amalgamated into one single 50-question document which will be administered as a single questionnaire at each assessment point. Quality of Life questionnaire compliance will be carefully monitored during this feasibility trial; this and clinical outcomes will be used as one basis for the sample size calculation for the SABRE 2 phase III trial. | — |
