Bhutan's First Emergency Air Medical Retrieval Service: The First Year of Operations

OBJECTIVE

The Bhutan Emergency Aeromedical Retrieval (BEAR) Team is the only helicopter emergency medical service in Bhutan. This study was performed to review the clinical cases cared for by the BEAR Team, ascertain the types of interventions that were performed, and determine the outcomes of patients evacuated in its first year of operations.

METHODS

This is a retrospective observational study in which medical evacuations performed in the first year of operations were analyzed. The number of airlifts activated during the study period determined the sample size (171). Data were obtained from case logs and trip sheets.

RESULTS

The BEAR Team provided services to all regions of the country in its first year. The overall survival rate was 73.1%. The most common intervention required was securing a definitive airway (n = 24). The top 3 conditions requiring air medical retrieval were sepsis, acute mountain sickness, and trauma.

CONCLUSION

Helicopter emergency medical services are known to decrease the time to definitive treatment. This is particularly pertinent in Bhutan, given the scattered population distribution, long transport times, and distribution of medical resources and specialty care. This study is the first of its kind in Bhutan, and this can pave way to conduct more studies involving patients transported by air ambulance.
