In 2022, more than 63,000 children of US military service members lived overseas. Among short term pediatric travelers, the most common reasons for seeking medical care include diarrheal syndromes, systemic febrile illnesses (including malaria), respiratory diseases, and dermatological conditions (including animal bites). Very little medical literature currently exists on the health outcomes of long-term expatriate children from the United States and little is known about the most common causes of hospitalization. Analyses specific to military children living abroad are similarly limited, either due to aggregation across the entire military health system, or narrowly focused on a specific context such as utilization of Air Force air transport resources in INDOPACOM. The US military family population differs from other expatriate civilian populations in that they have required pre-travel health screening for chronic conditions unsuitable for assignment at remote duty locations and are provided low to no-cost medical care prior to moving abroad to their overseas duty stations. Within this population of military children living abroad, those living on or near military bases with military medical facilities may also have differences in health care utilization and outcomes, compared to those at assignments, such as at embassies, that may involve closer contact with local communities and a reliance on host-nation health systems that results in different causes of illness and hospitalization across these specific populations. The aim of this study is to describe the epidemiology of pediatric hospitalizations among military health system beneficiaries stationed overseas. We hypothesize there will be variations in etiology and burden of hospitalizations across various age groups based on region and proximity to military health system facilities. The Military Data Repository serves as the data source for admission diagnosis codes, facility type and location, and patient demographics of admitted pediatric beneficiaries of US Active Duty military personnel assigned overseas. These results inform assignment screening considerations, pre-travel preventive medical care, and both staffing requirements and care capabilities for both military treatment facilities and patient transport systems.
