Auriculoterapia para reduçao do estresse ocupacional e melhoria da qualidade de vida em enfermagem na Amazônia: ensaio clínico randomizado

Abstract

Introduction: Studies focused on the health research of the nursing worker have been discussing the workload and conditions for the exercise of care that, when too unhealthy, lead to the illness of this professional. To cope with stress, nursing professionals develop coping strategies. We are based on the theory of management of the symptoms with the intervention of Auriculotherapy, one of the branches of traditional Chinese medicine. Objectives: To evaluate the effectiveness of Chinese auriculotherapy in combating stress and improving quality of life in nursing professionals active in hospital assistance. Method: Randomized and controlled clinical trial, with 73 nursing professionals with medium and high levels of stress, according to the list of symptoms of stress (LSS), of a public hospital in the city of Manaus (Amazonas), of the sectors of intensive care unit (ICU), Surgical Center (SC), Material and Sterilization Center (MSC). After withdrawals, an N of 56 professional women was obtained, which were divided into two groups: control group (G1) and Auriculotherapy Group (G2). The instruments used were: a questionnaire of sociodemographic data, the list of symptoms of stress of Vasconcelos (LSS), Work stress Scale (TSEs), Inventory of coping strategies of Folkman and Lazarus and an instrument of quality of life (SF12v2). The data collection was held from July to October 2017. The G2 received eight sessions of auriculotherapy with black mustard seeds twice a week and the participants responded to the instruments before and after the treatment. The ear-Point Protocol was: Shenmen, kidney, liver, lung, heart, brain stem and anxiety point. The average and standard deviation values were calculated for the variables and performed the descriptive statistical tests (Pearson square chi, variance analysis) and Intergroup analysis Inferential (T-test for independent groups). The research was approved by the Research Ethics Committee of the Federal University of Amazonas (UFAM). Results: Stress levels were considered high according to LSS for the initial sample of professionals. The G2 obtained 38% reduction in stress levels (LSS) with Cohen D index of 1.65 (P = 0,000), second Test T. and G1 did not have statistically significant difference to stress levels. As for TSEs, the G2 obtained 31% reduction, with Cohen index D of 1.64 (P = 0,007). The G1 did not get statistically significant difference. As for the coping inventory, after the treatment with auriculotherapy, the removal confrontation strategies suffered a large reduction of 36% in the frequency of use (P = < 0.05). There was no statistically significant difference between before and after in the physical and mental domains of the SF12v2. For Spearman's correlation tests between the instruments, a positive correlation was observed between the stress levels evaluated in LSS and TSEs, after treatment (r = 0,617/p = 0,000). and a negative correlation between LSS and the mental domain of SF12v2 (r = 0,489/p = 0,000). Conclusion: The Chinese auriculotherapy, with the proposed points protocol, managed to reduce the stress levels of nurses, technicians and nursing assistants of the ICU, SC and MSC, observed by the LSS and TSE instruments. It also obtained the reduction of frequency of use of the areas confrontation and removal, according to the inventory of coping. It did not have a statistically significant difference to the quality of life (SF12v2). In the correlation test, it was concluded that LSS and TSE instruments achieve similar results of stress levels and when there is stress reduction (LSS), there is an improvement in the mental domain of quality of life (SF12v2). More studies are needed, with a more significant sample, so that they can confirm the findings.
