Objective: A team-based disease management approach that considers comorbid conditions, social drivers of health, and clinical guidelines improves diabetes care but can be costly and complex. Developing innovative models of care is crucial to improving diabetes outcomes. The objective of this analysis was to evaluate the efficacy of virtual interdisciplinary diabetes rounds in improving glycemic control.
Study design: Retrospective cohort study using observational data from July 2018 to December 2021.
Methods: This study employed difference-in-differences analysis to compare change in hemoglobin A1c (HbA1c) in a group of patients whose providers received advice as part of virtual interdisciplinary rounds and a group of patients whose providers did not receive rounds advice. Patients with diabetes were identified for rounding (1) based on attribution to an accountable care organization along with an upcoming primary care appointment and an HbA1c between 8% and 9% or (2) via provider referral.
Results: The rounded group consisted of 481 patients and the comparison group included 1806 patients. There was a 0.3-point reduction in HbA1c (95% CI, 0.1-0.4) associated with rounds overall. In a subanalysis comparing provider adoption of recommendations among those rounded, provider adoption was associated with an HbA1c reduction of 0.5 points (95% CI, 0.1-0.9) at 6 months post rounds, although there was no significant difference in the full year post rounds.
Conclusions: Interdisciplinary rounds can be an effective approach to proactively provide diabetes-focused recommendations. This modality allows for efficient, low-cost, and timely access to an endocrinologist and team to support primary care providers in diabetes management.
