Clinical impact of Internet-based tools to guide therapeutic decisions for mantle cell lymphoma.

Mantle cell lymphoma (MCL) is a rare cancer with diverse management options. Although clinical practice guidelines have become ubiquitous across medicine, the utility of guidelines for MCL management is limited by provider awareness and the lack of a definitive standard of care. We sought to determine whether expert recommendations, delivered as an online decision support tool, impacted practitioners' therapeutic decisions with MCL. Participants were more likely than the experts to select aggressive regimens for both newly diagnosed and relapsed/refractory MCL. After seeing the expert recommendations, participants revealed that the expert opinion impacted their treatment choices in 103 of 365 clinical scenarios, suggesting that online decision support tools may increase the number of clinicians making treatment decisions for patients with MCL that are concordant with expert consensus recommendations.
