The relationship between quality of working life of nurses in educational hospitals of Kermanshah with their perception and evaluation of workload in 2017
Background and aims: Nurses are the most important support of treatment that is responsible for important tasks such as the patient's psychological and physical care. Due to the working conditions of nurses, the occurrence of physical and mental disorders of nurses plays an important role. Quality of work life is one of the most important issues in any organization that is the key to the success of any organization. Quality of work life was first highlighted with emphasis on different aspects of work and productivity of the organization. The quality of working life describes employee satisfaction in a safe environment with regard to promotion of the organization. Quality of Work Life, as a comprehensive program, is dedicated to enhancing the satisfaction and improvement of the quality of life of employees in the workplace, as it is a vital element in recruiting, retaining and enhancing the quality of human resources of any organization. Nurses are one of the most important pillars of the health care sector, which, depending on their occupational status, are responsible for important tasks such as mental and physical care of the patient. These activities play a significant role in the development of physical and mental disorders in the case of noncompliance with the principles of safety, tranquility and work welfare. Another major problem for nurses is high workload, which affects their attention capacity and increases medical errors. Several studies have shown that high workload can compromise the quality and safety of patient care, increase medical errors, increase the length of hospital stay, and ultimately reduce quality of service. High workload is highly correlated with poor quality of care and is one of the most important causes of stress in nurses. The purpose of this study was to determine the relationship between the quality of work life of nurses working in Kermanshah educational hospitals with their perception and evaluation of workload. Methods: This descriptive analytical cross sectional study was conducted on 873 nurses in Kermanshah educational hospitals in 2017. The stratified random sampling was performed according to the sample size and the number of nurses employed in each hospital. Nurses working in each hospital were selected by random sampling. Demographic data, Darren Van Laar Quality of Work Life Questionnaire and NASA TLX Workload Questionnaire were used for data collection. Generalized questionnaire designed to collect demographic data including sections of age, sex, marital status, work sector, work experience, average number of shifts per month, average number of patients per shift, and number of overtime hours per month. The validity and reliability of the NASA TLX Questionnaire for the Iranian population were assessed by Mazloomi et al. and its Cronbach's alpha was estimated to be 0.897. NASA TLX is a multidimensional method that provides a total score of workload based on the weighted average of six subscales of mental demand, physical demand, temporal demand, performance, effort, and frustration. This method has high validity and general acceptance and can be used to identify sources with high workload. Mean scores
