The stress experienced in an emergency medical service (EMS): A descriptive study.

INTRODUCTION:Stress, described as an adaptation of the body to an event, is a considerable problem among health workers, especially for those who work in emergency situations, as they very often have to face complex situations. It has been proven that stress affects the performance of health professionals, which is why it is interesting to measure it in these situations, to be able to know what methods to implement to reduce it in future events. Despite having previous measurements in healthcare personnel during clinical simulations, this study is relevant because stress has never before been measured in EMS professionals when performing their work. OBJECTIVE:To determine the acute stress experienced by professionals in an Emergency Medical Service (EMS) when handling five types of clinical emergencies. As secondary objectives, to determine if there were differences in the increases in stress in relation to sex, age, profession, team, and above all, type of emergency handled. METHOD:The following were measured for the analysis: physiological (mean heart rate (HR), systolic (SBP) and diastolic (DBP) blood pressure), and biochemical (salivary alpha amylase (sAA) activity) markers, before (Basal) and after (Post-Stress) the interventions of 27 professionals from an EMS. RESULTS:In general, the results obtained showed significant differences between the baseline measurement of physiological and biochemical markers versus the post-exposure measurement. Some of the differences in stress levels in relation to sex and professional role are striking. CONCLUSION:The determination of acute stress experienced by professionals from an EMS in a real emergency showed significant increases in the sAA enzymatic marker of acute stress. These results are the first data published in this regard, and could be used as a reference to follow in clinical simulation in the training of students and the training of nursing professionals. IMPLICATIONS FOR CLINICAL PRACTICE:Evidence based studies are needed to improve the education and training of emergency and intensive care professionals. The results from are a great step in the analysis of the real stress that professionals are subjected to when they handle different emergencies.
