Committee Chair
Hunter Nicholas, DNP, MHA, RN, TCRN

Committee Co-Chair
Diana Jewett BSN, RN, CCRN, TCRN

The Society of Trauma Nurses (STN) has established a Trauma Performance Improvement Special Interest Group (Trauma PI SIG), designed to bring together STN members who are responsible for trauma performance improvement initiatives within their institutions and/or interested in advancing trauma PI best practices.

This Benchmarking & Performance Metrics subgroup aims to assist trauma centers move beyond data collection toward using it strategically to drive measurable improvement, focusing on identifying, standardizing, and applying meaningful metrics that allow trauma centers to benchmark against national standards, peer institutions, and their own historical performance. Current work includes developing a shared library of core trauma PI metrics and definitions, reviewing best practices for risk-adjusted benchmarking (including TQIP data utilization), and building tools to help programs track performance over time and present findings effectively to leadership and trauma committees.

Diana Jewett brings a decade of trauma nursing experience to her work with the STN Trauma PI SIG. She began her career in the trauma ICU before transitioning into trauma performance improvement at a Level I trauma center, and later advanced into the role of Trauma Program Director. Diana now serves as Division Director of Trauma Operations for HCA Healthcare's Capital Division, where she oversees trauma performance and operations across nine trauma centers ranging from Level I to Level III designations.

Hunter Nicholas brings a decade of dedicated experience in trauma and performance improvement to her role as Chair of the STN Trauma PI SIG. Hunter's passion for trauma care took root early in her career at a small, Level IV trauma center in Kansas. That foundational experience continues to shape her approach to trauma PI today, grounding her work in a deep appreciation for the challenges and opportunities faced by trauma programs of every size and level. Hunter earned her Doctorate of Nursing Practice from Touro University Nevada in 2018 and currently works as a trauma leader at HCA Healthcare. In this role, she has the unique opportunity to collaborate with others to advance trauma performance improvement best practices across the enterprise.
