What this Trial Is About

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 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.
