Optimal Physical Space for En Route Care: Medic Posture and Injury Survey

Abstract

Introduction: An anonymous online survey was presented to active duty U.S. Army, Reserve, and National Guard Soldiers with experience as en route care medical providers with the intent of identifying factors which contribute to musculoskeletal disorders in U.S. Army en route care medical providers. The survey looked at transport vehicle design, equipment, and awkward postures that could play a role in causing injuries. Materials and Methods: Survey responses were received from 60 en route care providers regarding postures assumed during administration of en route critical care tasks, routine medical transport scenarios, and patient loading. Care providers reported gender, height, weight, experience, tasks, and awkward postures experienced. They also reported occupational injuries that occurred as a result of performing job duties, such as back, neck, and joint pain, injuries, and discomfort. Results: The survey was answered by 56 (93.3%) males and 4 females (6.7%) with an average of 7.34 years of experience as en route care personnel. Lower back injuries were suffered by 87% of respondents. The most common causes were awkward positions and lifting patients. There are statistically significant relationships between shoulder injuries and overextending, lower back injuries and overextending, and lower back injuries and reaching backwards, ankle injuries and care provider height, and knee injuries and the frequency at which care providers utilized the postures of kneeling, squatting, reaching behind themselves, and straining to lift a heavy weight. Loading and unloading patients from evacuation platforms was among the top causes of all awkward postures among respondents. Conclusion: Results of this survey emphasize the need for injury mitigation and prevention strategies to reduce impacts on soldier health and readiness.
