Abstract
To compare the efficacy of experimental auriculotherapy and placebo auriculotherapy with sham points for the treatment of stress in nurses of a charity hospital in São Paulo. Randomized, single-blind, controlled trial. The sample consisted of 168 nurses with medium and high stress levels according to the List of Stress Symptoms (LSS). The participants were randomized to three groups: Auriculotherapy (G1), Placebo (G2) and Control (G3). Groups 1 and 2 received 12 sessions, twice a week. The points used in Group 1 were: Shenmen and Brainstem; in Group 2 the points were: External Ear and Face Area. The three groups were evaluated at baseline, after eight sessions, 12 sessions and in a follow-up (after 15 days). Group 1 achieved a 43% reduction and a 1.81 Cohen d index (high effect), presenting statistical difference after eight sessions, maintained in the follow-up evaluation (p <0.001), according to Analysis of Variance. Group 2 achieved a 26% reduction, with Cohen's d index of 0.86 (great effect), achieving a difference after 12 sessions (p<0.001), maintained in the follow-up (p <0.05). The G3 did not present stress reduction. Experimental auriculotherapy achieved greater stress reduction among nurses, but there was no statistical difference between the two intervention groups. Brazilian Registry of Clinical Trials: RBR-req2792.
Highlights
In the early twentieth century, the endocrinologist Hans Selye called “General Adaptation Syndrome” the set of similar non-specific responses in people who are experiencing distressing situations[1]
Situations considered new, unpredictable, ego threatening and/or uncontrollable can lead to physiological responses to stress, which are activated by the autonomic nervous system (ANS) and neuroendocrine system trying to find an adaptation to the stressful situation[2]
Chemical and biological risks that exist in the workplace of nursing professionals, there are psychosocial risks related to work, which have been identified as one of the major current challenges for the health of workers and are related to problems such as stress, violence and harassment at work[4]
Summary
In the early twentieth century, the endocrinologist Hans Selye called “General Adaptation Syndrome” the set of similar non-specific responses in people who are experiencing distressing situations[1]. In 1936, he began to use the word stress to define the physiological reactions of the organism when facing a situation that requires effort, triggered by a threatening stimulus. In his conception, stress consists of three successive stages: alarm stage, resistance and exhaustion. Stress influences the psychosocial well-being of individuals, especially of workers. It can have negative consequences for the performance of Nursing professionals, affecting the institution and the work process with absenteeism, high turnover and low quality care[3]. Chemical and biological risks that exist in the workplace of nursing professionals, there are psychosocial risks related to work, which have been identified as one of the major current challenges for the health of workers and are related to problems such as stress, violence and harassment at work[4]
