It is a time of significant change as the Military Health System (MHS) transitions to the purview of the Defense Health Agency (DHA). Additionally, the landscape of combat is ever changing, and military medicine needs to evolve to ensure that the lessons learned are utilized to optimize care of the war fighters. The purpose of this review is to evaluate the available literature on existing operational medicine curriculums and make recommendations to restructure current military medicine training to produce operationally prepared clinicians who are informed in operationally focused research principles.
Operational Medicine
Before diving into the importance of creating a curriculum and investing in training for scholarly activity proficiency, operational medicine needs to be defined. It can be defined as medical care provided in an austere environment with limited resources and possibly under hostile conditions. Another way to look at operational medicine is as the evaluation of normal human physiology and pathology under abnormal conditions. The mission set of each of the services is unique. The Marines and Army may operate forward past the wire vulnerable to the environment, gunfire, and improvised explosive devices, remote from fixed medical facilities. The Navy has divers exposed to the risks of decompression sickness. The Air Force has pilots exposed to altitude changes and strains of G-forces during flight. Locations vary from cold high-altitude mountainous regions to high-temperature desolate deserts. Many times, medical practitioners may be remotely stationed, far from specialty or immediate definitive care. Patient care may consist of low-acuity management of individual patients in sick call to mass casualty events where patient numbers and morbidity may outstrip available resources, making the difficult task of triage necessary.
Despite the challenges of being a uniformed physician, the benefits of being embedded is a better understanding of the roles and capability of the unit. Military physicians need to have the unique knowledge of the type of injuries sustained in that particular theater of war, such as differentiating between the trauma pattern and care required for blast injuries vs high-velocity missiles. There are also chemical, biologic, radiologic, and nuclear threats that military physicians need to recognize. Much of what disables a military fighting force is not a direct relationship to combat-related injuries; however, entire units have been taken down by infectious diarrhea or trench foot. There is also a need for familiarity of the infections and parasitology endemic to the particular theater with the aim of implementation of prevention whenever possible.
Military medicine does not fit in any box. Military physicians need to know the job requirements of various specialties, including elements of occupational medicine, such as aircrew piloting high-performance fighters or ground troops fully loaded with body armor and 80-lb backpacks. There are musculoskeletal injuries from the stressors of various military occupations. Working around weaponry and contact with hostile forces will create scenarios requiring emergent and critical care. In addition to physical injuries, there is the mental strain of combat with the risk of imminent personal injury, the guilt of survivorship, dealing with the scars and permanent physical damage of combat, and prolonged separation from family and other support systems.
The National Defense Authorization Act 2017 mandated the establishment of a standardized process to oversee all military graduate medical education (GME) programs with the goal of ensuring medical operational readiness.1 This is no small task with > 3000 residents in more than 70 specialties, comprising approximately 12% of US residents.1,2 Presently, 26 to 32% of the medical corps is enrolled in full-time training compared with 12% of the total force.2 With significant time and resources expended during this period, it is vital to maximize the potential of the training.
Literature Review
A literature review was performed, evaluating historical precedence of specialized military medical training and research as well as current operational curriculums. Literature search was conducted in the PubMed and Uniformed Services University (USU) Learning Resource databases using the terms “operational medicine curriculum,” “military medicine curriculum,” “operational medicine training,” “military medicine training,” “operational medicine research,” and “military medicine research,” and included all articles from 1997 to 2020. Inclusion criteria included studies that detailed military medicine training programs and/or outcomes. The source types used in this research project included peer-reviewed journal publications—both review articles and original research—from medical and military journals. The citations of these articles were also reviewed for additional usable publications. Secondary sources included official reports and studies by the RAND Corporation, the US Government Accountability Office, and the Institute for Defense Analysis (IDA). Due to lack of literature on the topic, other sources such as talking papers, letters, and formal presentations from subject matter experts were included to showcase the current state and gaps on this topic. Key findings from peer-reviewed publications are presented in Table 1.
Overall, the literature review showed that longitudinal deliberately mapped out curriculums can be well integrated into the existing medical curriculum.3 The military medicine course topics include environmental medicine, applied field medicine, combat casualty care, medical support planning, mass casualty incident preparation, and military-focused problem solving, decision making, and leadership.4
One 1997 study looked at the degree of implementation of military unique curriculum in 18 family medicine residencies. Only 30% of residents stated that their program had a specific operational medicine curriculum.5 Salerno and colleagues surveyed current residents and recently graduated internal medicine physicians at 14 facilities in the Army, Air Force, and Navy to determine confidence level with military medicine. More than half did not feel ready to practice deployment medicine; just 19% felt comfortable treating nuclear, biologic, and chemical warfare injuries; and 32% felt unfamiliar with the command and administrative duties. A subgroup analysis showed that USU graduates felt more prepared in these areas compared with civilian program graduates.6 Additional studies showed perceived smoother transition in the first active-duty tour after participation in an operational curriculum.7
