Impact of Co-management at the Primary-Subspecialty Care Interface on Follow-up and Referral Patterns for Patients With Concussion.

Background: Co-management is a collaborative care model that consists of structured tools to define and document care delivered by 2 or more providers. We evaluated the impact of implementing co-management at the interface between pediatric primary care providers (PCPs) and subspecialists.

Methods: Participating PCPs (n = 9) were trained on management of concussion using the co-management tools. Co-managed patients with concussion were prospectively enrolled (n = 148) and compared to a retrospective audit of non-co-managed patients (n = 50).

Results: PCPs using co-management demonstrated adherence to the tools. PCPs were significantly more likely to provide follow-up care to patients when using the co-management tools. All participating PCPs reported that co-management enhanced their expertise in caring for patients with concussion.

Conclusions: Co-management can enhance PCPs' capacity to independently manage the care of patients with concussion. Co-management led to an observed change in practice that merits further exploration in terms of cost, quality, and clinical outcomes.
