Tradução e adaptação transcultural para o português brasileiro do Air Medical Prehospital Triage (AMPT) Score for Helicopter Transport of Trauma Patients

Abstract

The need to transport trauma victims - whether due to a lack of resources in a hospital unit or due to emergency pre-hospital care - finds air activity an important ally. Transport by air using fixed-wing aircraft (airplanes) or rotary wing (helicopters) reduces treatment time, and improves survival and quality of life. Due to its costly maintenance and operation service, air transport of victims depends on appropriate triage criteria for patients eligible for this type of transport. The Air Medical Prehospital Triage (AMPT Score) for helicopter transport of trauma patients is a scale developed and validated in the United States of America that quickly classifies the trauma victim as likely to benefit or not from helicopter transport. The aim of this study was to translate the AMPT Score and cross-culturally adapt it to Brazilian Portuguese. This study followed international guidelines for standardized translation process and was developed from: scale translation, scale back translation, comparison of back translation with the original scale, assessment of equivalences by the expert committee, proposal of the previous version of AMPT Score, application of pre-test/post-test and proposition of the final version of the translated scale. All stages were followed by the developer of the AMPT Score and documented. The Wilcoxon Test comparing the experts’ assessment with the positive expected (completely equivalent) resulted in p-value = 0.0625 (General). The Content Validity Index (CVI) of experts committee calculated was 0.9479. The pre-test data resulted in a Cronbach’s Alpha 0.920 ± 7.26. The Free-marginal Kappa coefficient of pre-test data was 0.89 [95% CI for free-marginal Kappa (0.86,0.93)], percent overall agreement 94.65%. The post-test data resulted in a Cronbach’s Alpha was 0.925 ± 5.36. The Wilcoxon Test comparing pre-test with post-test resulted p value 0.0942. The process resulted in the translation of the AMPT Score with the appropriate equivalences proposed by the literature and statistically reliable. The findings described might serve for future validation of the instrument, which will be of great value to professionals who work with transporting trauma victims in helicopters.
