A Virtual Tumor Board Platform: A Way to Enhance Decision-Making for Complex Malignancies.

Introduction: Multidisciplinary tumor boards (TBs) are crucial for decision-making and management of patients diagnosed with complex malignancies. The social distancing conditions imposed by coronavirus disease 2019 presented an opportunity to compare virtual versus in-person TBs.

Methods: A retrospective analysis of attendance data from an National Cancer Institute-designated cancer center's gastrointestinal (GI) TB participant data from September 2019 to October 2020. In addition, an online survey assessing the virtual TB experience was sent to participants of all TBs. Interrupted time series analyses were performed to evaluate preintervention and postintervention GI TB attendance only.

Results: The overall mean attendance for GI TB was 30 participants; turnout was higher for virtual format compared to in-person (32 versus 23 attendees, P < 0.001). This increase was seen across all participant categories: attending physicians (15 versus 11 attendees, P < 0.001), trainees (11 versus 8, P < 0.001), and support staff (6 versus 3, P < 0.001). There was no significant difference in the mean number of cases discussed between TB formats. The majority of the 141 survey respondents (across all TB) were attending physicians with >20-year experience. Most supported a permanent virtual or hybrid TB format, 72.5% found this format to be more time efficient and with similar productivity, and 85.8% found it easier to attend. The majority (89.9%) felt confident that the decision-making process was not affected by virtual interactions.

Conclusions: A virtual platform for multispecialty TBs allows for greater attendance without sacrificing the decision-making process. This survey supports continuing with a virtual or hybrid format, which may increase attendance and facilitate access to multidisciplinary discussions leading to improved patient care.
