THE IMPACT OF SHIFT WORK ON PSYCHOSOCIAL FUNCTIONING AND QUALITY OF LIFE AMONG HOSPITAL-EMPLOYED NURSES: A CROSS-SECTIONAL COMPARATIVE STUDY

Background: Approximately 20% of the European labour force is involved in some type of shift work, with nurses being on the forefront. In Bosnia and Herzegovina, a specific work scheme is pervasive in the health care arena, where all nurses involved in shift work are committed to eight night shifts per month - unlike other European countries that restrict the number of night shifts. Accordingly, we aimed to investigate whether such shift work significantly affects psychosocial functioning and the quality of life of hospital nursing personnel in this country. Subjects and methods: A comparative cross-sectional study design was applied on a total of 157 hospital nursing professionals at the University Clinical Hospital Mostar during 2019. Subjects were divided into two groups: a total of 51% study subjects worked in specific shifts (12-hour day shift / 24 hours off / 12-hour night shift / 48 hours off), while 49% subjects worked in accordance with the regular 7-hour daily schedule. Standard Shiftwork Index (SSI) questionnaire was used, alongside comprehensive socio-demographic and quality of life appraisal. Descriptive and inferential statistical methods were applied, and statistical significance was set at p<0.05. Results: This study demonstrated increased amounts of stress, reduced coping abilities and reduced levels of life enjoyment in shift work nurses in comparison to day work nurses. Furthermore, increased anxiety, stress, psychoorganic symptoms and sleep disturbances were significantly more common in shift work hospital nursing staff. In our study, nurses that worked in shifts have experienced negative externalities such as decreased social functioning, as well as reduced family and leisure time. Conversely, significantly higher satisfaction rates with shift work were only shown in regards to compensation. Conclusions: Our results reveal many detrimental effects of shift work and contribute to the field of research that is still laden with gaps in understanding its exact impact on the overall health of nursing personnel. Going forward, prospective (and even interventional) studies will be needed to disentangle the exact interplay between work-related factors in various health care systems and subsequent psychosocial disorders in health personnel.
