Integrating a Disease-Focused Tumor Board as a Delivery-of-Care Model to Expedite Treatment Initiation for Patients With Liver Malignancies.

Abstract

Patients with hepatobiliary malignancies are especially vulnerable to treatment delays. This study sought to evaluate the impact of implementing a new delivery-of-care model centered around a hepatobiliary multidisciplinary tumor board (HB-MTB) and integrated with an optimized patient workflow process to expedite treatment initiation. A hybrid type 2 study (effectiveness-implementation) was performed. Implementation measures were examined prospectively using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) approach during 5 years after the HB-MTB program deployment (2015-2020). The primary outcome was effectiveness, measured as time to treatment initiation (TTI) using a before and after design (1 year each). The patients were grouped into before (BP) and after (AP) categories based on date of HB-MTB program implementation. Multivariable Cox and linear regression analyses were performed to examine and compare time to treatment initiation between groups. The HB-MTB program enrolled 2457 patients (reach). The RE-AIM measures were favorable and improved over time (P < 0.01 for all). The median TTI was lower for the AP group than for the BP group (17 vs 24 days; P < 0.01). In the multivariable Cox and linear regressions, treatment in the AP group was associated with a faster TTI (hazard ratio, 1.75; 95 % confidence interval, 1.31-2.35; p < 0.01), and a mean of 13 days faster treatment initiation than the BP group (P < 0.01). Implementation of an HB-MTB program integrated with an optimized patient workflow was successful and led to faster treatment initiation. This delivery-of-care model can serve as a blueprint to expedite treatment of patients with cancer.
