RESUMO
BACKGROUND: Good physical and mental health of employees is one of the major characteristics of a healthy organisation. AIM: Due to the importance of occupational burnout and its potentially negative consequences, the aim of this study was to assess occupational burnout and its related factors among Iranian nurses. METHODS: In this cross-sectional study, 205 nurses who were working in two educational hospitals affiliated with Shahroud University of Medical Sciences were included. Forty-two of the nurses were male, and 163 were female (mean age: 31 years). Maslach Occupational Burnout Inventory, demographic and job characteristics questionnaires were completed for each nurse. Questionnaires were then collected, and data were analysed statistically by SPSS, version 22. RESULTS: In the assessment of occupational burnout, the highest level was observed in emotional exhaustion and then in personal performance. There was a significant difference between the frequency of nurses' emotional exhaustion domain in terms of gender (P < 0.05), so that, women suffered more from emotional exhaustion. There was a significant difference between the frequencies of nurses' performance in terms of marital status (P < 0.05) so that married people had more personal performance disorder. CONCLUSION: The results of this study showed that nurses suffered from low occupational burnout. Female gender, sleeping disorders, awakening at night and employment in stressful wards such as the emergency ward was associated with a higher level of occupational burnout in nurses.
RESUMO
PRIMARY OBJECTIVE: The present prospective study was performed to investigate whether primary clinical findings and serum S100B concentrations at 3 and 6 hours post-trauma can contribute to the selection of patients for an initial computed tomography (CT) scanning. RESEARCH DESIGN AND METHODS: S100B was measured in serum samples obtained at 3 and 6 hours after the injury. Adjusted odds ratios (OR) and 95% confidence interval (CI) associated with demographics and clinical predictors of positive CT scan were calculated. Sensitivity, specificity, negative and positive predictive values were also calculated for S100B levels. MAIN OUTCOMES AND RESULTS: It was found that the presence of loss of consciousness (OR = 2.3; 95% CI = 1.00-4.01; p = 0.008) and post-traumatic vomiting ≥ 2 episodes (OR = 1.8; 95% CI = 1.08-3.29; p = 0.019) are factors associated with positive CT scan. In this study the best cut-off point of 0.115 µg L(-1) for 3-hour S100B has sensitivity of 94.9% (95% CI = 86.8-98.3) with specificity of 35.4% (95% CI = 25.2-47.0) to predict intracranial injury on CT scanning. The corresponding results for 6-hour S100B > 0.210 µg L(-1) were 98.7% (95% CI = 92.1-99.9) for sensitivity and 39.2% (95% CI = 28.6-50.8) for specificity. CONCLUSIONS: Serum S100B measurement along with clinical evaluation of patients with mild traumatic brain injury has promising screening value to support selection of patients for CT scanning.
