 Aims and Objectives. The proposed research aims: firstly, to enhance our understanding of patient concerns, lifestyles, and values, that influence their choice of bladder reconstruction and predict their treatment satisfaction and quality of life QoL; and, secondly, to initiate the development a novel decision-aid tool to help bladder-cancer patients, their families, and medicalhealth professionals to choose the reconstructive surgery following bladder removal that best suits a patients needs. To these ends, a complementary combination of qualitative and quantitative research approaches will be employed to obtain information from patients about the reasons for their reconstructive surgery choices, the aspects of their lifestyle that were most important to them in reaching their decisions, and the degree to which they are satisfied with their reconstruction. These findings will be used to inform the items to be contained in a pilot joint decision-making tool to support patients and medical professionals when planning such life-changing surgery. Such a tool ultimately could support patient choice, enhance QoL, and influence decision-making practice. Thus, the specific objectives of the research will be to: 1 identify the factors important for patients when choosing a bladder reconstruction; 2 establish the degree to which these factors predict satisfaction with the reconstruction; and, ultimately, 3 start to develop a joint decision-aid tool for patients and medical staff, to use when deciding on the choice of diversionary procedure, that highlights these key factors predicting success and better QoL following different forms of bladder reconstruction.
