Protocol to Develop a Core Outcomes Set for Peripheral Nerve Injury.

Abstract

Background: Advances in treatment philosophies and microsurgical techniques for peripheral nerve injuries (PNI) have led to improved outcomes. However, lack of standardisation in the evaluation of clinical outcomes after PNI treatment precludes the ability to compare reconstruction methods, such as nerve transfer, nerve grafting, free functioning muscle transfers and tendon transfers. To this end, our goal is to work collaboratively to establish a core outcome set to evaluate outcomes after PNI. Methods: The protocol for this arc of work, delineated in this manuscript, consists of two phases: (1) conducting a systematic review of how outcomes are currently reported following PNI and (2) a Delphi process to gain consensus on the measures to include in the core outcome set for PNI. In the Delphi process, two online rounds will be used to gather consensus on the importance of each outcome measure. A final round will be conducted in person to discuss and resolve measures for which there is not yet consensus and to finalise the core outcomes set. Conclusions: Through this process, a common standard for reporting outcomes after PNI will be created, facilitating collaboration and future research.
