Abstract: Research on the healthcare needs of active military personnel is robust, but less attention has been paid to the healthcare needs and experiences of their families. While military personnel often receive comprehensive healthcare through military systems, their families face varied levels of access depending on jurisdiction. This rapid review explores healthcare access for families of active military personnel across six high-income countries—Canada, the United States (US), the United Kingdom (UK), Australia, Germany, and France—highlighting key differences and considerations for Canada.
