Tests a shared decision-making tool for people with breast, prostate or melanoma cancer

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 set of questionnaires, one week after their decision-making consult. Encompassing the following questionnaires (I-SHARE for perceived Shared Decision Making, Control Preferences Scale for the perceived roles in the actual decision, Decisions Made, Decisional Comfort Scale, SCIP B Information Provision, PEPPI-5 Perceived Efficacy in Patient-Physician Interactions, Trust in Oncologists, Health Literacy) and for the cost-effectiveness analysis for our partner (UMIT TIROL) the EORTC QLU C10-D and EQ-5D5l will be added to assess utilities. In the post-test participants will receive the second set of questionnaires, 6 months after the first set of questionnaires. This set encompasses (Healthcare Integration INTEGrate, Person Centered Coordinated Care Experiences P3CEQ, Decisional Regret Scale, Trust in Oncologists, EORTC QLU-C10D, EQ-5D5L, Productivity Cost Questionnaires.

This study includes a pre-implementation comparison group, and results will be compared with post-implementation outcomes.

Participants will complete the questionnaires and provide demographic and clinical data (consent for sharing medical file is asked) and an audio-recording of their consultation will be made. Participants in the post-phase will participate in interviews about their experiences with the implementation of MetroMapping.

The audio-recordings will be transcribed and analyzed using the OPTION and 4SDM coding instruments. Data will be analyzed using both univariate and multivariate statistical methods. Transcript of audio-recordings will be analyzed using thematic analysis and the coding instruments.
