One Health and veterans' post-deployment health

Since 2001, more than 3.3 million US service members have been deployed to operations Iraqi Freedom, Enduring Freedom, New Dawn, Inherent Resolve and Freedom's Sentinel. Visible and invisible war wounds from direct combat experiences, coupled with environmental exposures to harmful substances, can complicate veterans' health throughout their lifespan. While promoting a holistic view of health, health professionals should be attentive for potential risks associated with environmental or animal exposures (One Health concept). During deployment, infectious and non-infectious environmental exposures and harmful substances in the air, on the land and in the water may result in immediate- or long-term health effects. Veterans can also face psychosocial health risks when home that may impact their concentration, emotional responses and social interactions. To strengthen health professions education, the authors recommend that curricula incorporate a comprehensive overview of veterans' physical and psychosocial health risks as a result of their deployment. They describe four specific curriculum topics, competencies and didactic methods that can reinforce veteran-specific content for clinical education and training. By applying the One Health concept, health professionals can document harmful environmental exposures during deployment, report gaps in clinical practice, and provide support for veterans' physical and psychosocial health needs when returning to civilian life.
