Combining Models to Solve the Problem: Macroergonomics and Public Health

Abstract

Macroergonomic and Public Health approaches were combined with typical ergonomic injury prevention approaches. This combination permitted a thorough investigation of all systems and personnel that might impact on musculoskeletal injuries among U.S. Army students attending Advanced Individual Training as a Combat Medic. The results allowed for an evaluation of the process, the attitudes and beliefs of the cadre (supervisors), and permitted development of a more harmonized, holistic injury prevention program. The results demonstrated success in terms of positive attitudes toward the program, an overall 10.8% reduction in clinic visits for musculoskeletal complaints, a 37% decrease in limited duty days, and a 60% decrease in sprain and strain injuries. A targeted prevention program yielded 36% fewer clinic visits and a 50% reduction in limited duty days. The high level of success achieved by this program was in large part due to the combined processes employed to lay a sound foundation for assessment, design, and evaluation of occupationally based musculoskeletal injuries.
