 Pilot Tool Development Converging themes emerging from the two studies in terms of predicting satisfaction with IC and NB will be drawn together, and a decision-aid tool will be produced for future study. The items identified for inclusion in the tool will be sent to a range of health professionals involved in delivery of surgery and physiotherapy consultant surgeons, registrars, clinical nurse specialists, and past patients to obtain their views on its face validity. Items that are rated as inappropriate or redundant will be re-assessed and potentially excluded from the tool, and any missing areas of importance identified by the expert panel will be re-examined.
