About this study

The goal of this observational study is to evaluate the impact of MetroMapping (a service design methodology) on Shared Decision Making in cancer care paths. The goal is to improve Shared Decision Making and make cancer care paths less overwhelming. The study will include adult participants (older than 18 years) with breast, prostate and melanoma cancers. The main question is How does the implementation of MetroMapping improve Shared Decision Making in cancer care paths. 500 patients, across the Netherlands, Spain, and Denmark, will be enrolled in a pre- and posttest phase. Including 100 breast cancer, 100 prostate cancer, and 50 melanoma patients per phase. To further understand patient experiences, the researchers will audio-record and transcribe the Shared Decision Making consultation of a subset of participants (10 per tumor type per country). A total of 120 audio-recordings across both study phases will be collected. In the post-test phase, a personal care path navigator will be created and the researchers will conduct interviews with 3 patients per care path and interviews with clinicians (12 per country, a total of 36) to assess their experiences with MetroMapping. The study is a pre-test and post-test multiple methods design, gathering both quantitative and qualitative data across care paths in the Netherlands, Spain and Denmark. Quantitative data will be collected via electronic (Castor EDC \& RedCap) and paper questionnaires. Participants will receive the first se…
