Medevac Utilization and Patient Characteristics in Rural Alaska 2010 to 2018

Abstract

ObjectiveLittle is known about medevac utilization in remote, rural Alaska where there is no road access and communities are reliant on medevacs for emergency care. With high financial costs and risks to flight crews, there is an urgent need to understand medevac utilization in rural Alaska. This article aimed to describe medevac utilization and patient characteristics over 9 years in the remote, air transport dependent in Alaska. MethodsDeidentified data (2010-2018) were obtained for all medevacs originating within the Yukon-Kuskokwim Delta. Descriptive statistics were calculated, and chi-square tests of independence were conducted to identify differences. ResultsFour thousand nine hundred ninety-one medevacs were performed, averaging 555 (standard deviation = 67.7) per year. Medevacs for respiratory complaints were predominant for children, whereas trauma predominated for adults 18 to 40 years old. Traumatic injury was more common in males than females aged < 65 years but was more common in females than males aged ≥ 65 years. Significant variability occurred in medevacs based on the community and the hour of the day. ConclusionMedevacs are a critical part of health care in rural, remote Alaska but appear subject to clinical and nonclinical determinants. These baseline data provide a foundation for future studies aiming to increase medevac safety and provide decision-making support.
