Buyukasik, M. The Effect of Workload on Work-Related Strain and Burnout Levels in Critical Care Nurses. Hacettepe University Graduate School of Health Sciences, Department of Internal Medicine Nursing, Intensive Care Nursing Master’s Program Master’s Thesis, Ankara, 2025. This descriptive and correlational study was conducted to examine the effect of workload on work-related strain and burnout levels of intensive care nurses. The study was conducted with nurses working in adult intensive care units (ICU) of Ankara Bilkent City Hospital between June 2024 and November 2024. The study included 200 ICU nurses. Nurse Introduction Form, Therapeutic Intervention Scoring System-28 (TISS-28), Work Related Strain Inventory (WRSI) and Maslach Burnout Inventory (MBI) were used to collect the data. Data were analysed using One- Way ANOVA, Independent Sample t Tes, Pearson Correlation Analysis and Multiple Linear Regression Analysis. The mean age of the nurses was 27.05±2.97 years, 79% were female, 73.5% were single, 92.5% were undergraduate, 61.5% worked in the general ICU and 92.5% worked in day and night shifts. The mean TISS-28 total score was 54.52±16.05 (high therapeutic work), the mean WRSI score was 42.61±7.00 (medium level of strain) and the mean MBI total score was 49.59±10.14 (medium level of burnout). It was found that the workload, work-related strain and burnout levels did not show a significant difference (p>0.05) in terms of variables such as age, gender, marital status, shift type, working time in the profession, ICU working time, while it was determined that the workload increased significantly as the number of patients they cared daily and weekly working time increased (p<0.05). In addition, while the workload of nurses did not have a significant effect on the level of work-related strain and burnout (p>0.05), it was found that the level of work-related strain significantly increased the level of burnout (p<0.05). In line with the results of the study, it is recommended to conduct further studies in which more detailed characteristics of patients and nurses are discussed to determine the effect of workload on work-related strain and burnout levels of intensive care nurses.
