بار کاری ناشی از اجرای وظایف در شغل پرستاری در بخش‌های مختلف یک بیمارستان

Background & objective: High workload may lead to increase human errors, compromise quality and safety of care, and reduce the nurses&rsquo; quality of working life. The aim of this study is to determine the task-induced workload in nursing. Methods: This is a descriptive analytical study. All of 214 nurses of one of the educational hospital took part in. After obtaining informed consent from participants, data were collected based on NASA-TLX questionnaire and the desired level assumed less than 50%. Analysis of data was performed by descriptive statistics and Anova in SPSS software (version 11. 0) at significant level of 0.05. Results: The results showed that perceived mental pressure for nurses is more than other NASA-TLX subscales (P< .001). Also, the mean perceived workload was more than 50%. However, mean workload score of NASA-TLX showed significant correlation with age (P< .001), work experience (P< .001), shift work (P< .02), and department (P< .001). Conclusion: The results show that effective programs will be required to reduce the work load, and to enhance nurses' performance.
