Expeditionary Research Interest Group (ExRIG)


The TSNRP ExRIG brings together nurses with diverse clinical, scientific, and methodological experiences to foster transformational advancement of innovative, operationally-relevant combat nursing research that modernizes the care of the future warfighter across Multi-Domain Operations (MDO).


The Expeditionary Care Research Interest Group (ExRIG) is a collaborative tri-service community of professionals focused on innovating, improving, and modernizing mission-critical nursing resources and proficiencies related to combat care during MDO. The ExRIG serves as an educational and professional resource, network, and support platform to ensure highly adaptive and effective care of the warfighter in the future Operating Environment (OE) through validated operational paradigms, research ideas, and best practices. The ExRIG will explore a variety of topics and issues pertinent to the transformation and modernization of nursing care concepts, capabilities, and capacity on the future battlefield. The ExRIG will build upon existing efforts to promote programs of research that advance the knowledge in these relevant areas and coordinate the translation of that knowledge into evidence-based practices supporting highly reliable care across all echelons. In 2021 the ExRIG consisted of 138 members, and produced 21 publications and 9 funded studies among leaders and members.



Through research and evidence-based practice, the ExRIG will lead the advancement of creative, innovative, and operationally-relevant combat nursing care. The ExRIG will transition scientific findings to the operational environment with a focus on manning, training, and equipping the joint nursing force to quickly prepare and execute optimized patient care across the full range of military operations worldwide.
