Abstract
BACKGROUND: Nurses work in a shift system that determines the provision of round-the-clock care of a patient in hospital conditions; however, it entails health consequences. OBJECTIVE: The aim of the study was the evaluation of work conditions of nurses engaged in shift work in hospital wards during the COVID-19 pandemic. METHODS: The study was conducted in 2020, and included 108 nurses working in a shift system in hospital wards. The research method was a diagnostic survey, using an author-constructed questionnaire. RESULTS: 88.9% nurses reported a negative effect of shift work on their physical health: 'musculoskeletal pain', 'elevated arterial blood pressure', and 'hormonal disorders' - 54.5% of respondents used pharmacological treatment. The causes of physical disorders were: 'microclimate', 'physical effort', 'noise', and 'forced body position'. Shift work exerted a negative effect on psychological health of the majority of respondents (75.0%): 'deconcentration', 'sleep disorders', 'feeling of occupational burnout' - treatment in 38.9% of respondents. Psychological health disorders were caused by: 'circadian rhythms disturbance by shift work', 'chronic stresses', and 'conflicts at work'. 69.7% of respondents reported that their shift work was disturbed by organizational factors, including: a 'badly planned work schedule', 'enhanced pace of work due to staff shortage', 'ambiguous division of duties, rights, responsibilities', 'shortages of equipment at the workplace'. CONCLUSION: The examined nurses experienced a negative effect of shift work on their physical and psychological health which, for some of them, was the cause of pharmacological treatment. Many organizational factors hindered the work of nurses in a shift system in hospital wards.
