This study examines the patterns of health service use among Rhode Island's Southeast Asian refugees, using Medicaid/Refugee Medical Assistance data. It was found that this group has a lower rate of health service utilization than the general Rhode Island population. Following the 3-month initial resettlement period during which mandatory health screening occurs, the use of health services begins to decrease. The types of services most used by refugees are outpatient services, and the most used ambulatory care facilities are the community health centers; hospital admissions and emergency room visits are not common. These findings suggest that the health care needs of Southeast Asian refugees are compatible with the health care principles of HMOs. However, the group's high usage of community health centers and the successful and long-standing experience these centers have had with the refugees indicate that they are a very appropriate means of health care delivery for Southeast Asian refugees. Based on this evidence, it is suggested that a Community Health Center-Primary Care Network model would be the best option for improving refugee medical assistance/service delivery. Low health service use rates also imply a low demand for health services, which indicates that the refugees' need for third-party coverage stems chiefly from the fear of catastrophic medical expenses rather than from actual use of services as a result of on-going illnesses. Extensive tables and charts are included at the end of the report. (CG)
