National virtual multidisciplinary team meetings have been established in Swedish cancer care in response to centralized treatment of rare cancers. Though national meetings grant access to a large multidisciplinary network, we hypothesized that video-based meetings may challenge participants' contributions to the case discussions. We investigated participants' views and used observational tools to assess contributions from various health professionals during the multidisciplinary team meetings. Data on participants' views were collected using an electronic survey distributed to participants in six national multidisciplinary team meetings for rare cancers. Data from observations were obtained from the multidisciplinary team meetings for penile cancer, anal cancer, and vulvar cancer using the standardized observational tools Meeting Observational Tool and Metric of Decision-Making that assess multidisciplinary team meeting functionality and participants' contributions to the case discussions. Participants overall rated the multidisciplinary team meetings favorably with high scores for development of individual competence and team competence. Lower scores applied to multidisciplinary team meeting technology, principles for communicating treatment recommendations, and guidelines for evaluating the meetings. Observational assessment resulted in high scores for case histories, leadership, and teamwork, whereas patient-centered care and involvement of care professionals received low scores. National virtual multidisciplinary team meetings are feasible and receive positive ratings by the participants. Case discussions cover medical perspectives well, whereas patient-centered aspects achieve less attention. Based on these findings, we discuss factors to consider to further improve treatment recommendations from national multidisciplinary team meetings.
