Healthcare in Guam

Guam is a U.S. territory in the western Pacific Ocean with a population of approximately 170,000 residents. As the largest island in Micronesia and a major U.S. military hub, Guam has a unique healthcare landscape that serves both civilian residents and a significant military population. Healthcare delivery faces challenges including geographic isolation from the continental United States, limited specialist availability, and the need to medically evacuate patients for complex procedures.

The primary civilian hospital is Guam Regional Medical City (GRMC), a private hospital that opened in 2016 and is the island's most modern medical facility, offering a range of specialty services including cardiology, oncology, and orthopedics. Guam Memorial Hospital Authority (GMHA) is the public hospital, providing emergency services, general medicine, and community health programs. The military population is served by Naval Hospital Guam, which also provides some services to eligible civilians.

The Guam Department of Public Health and Social Services (DPHSS) (dphss.guam.gov) oversees public health programs and healthcare licensing. Guam participates in Medicaid under a block grant arrangement. Residents requiring complex specialty care typically travel to Hawaii, the Philippines, or the continental United States. Telehealth has become increasingly important for connecting Guam residents with specialists.
