Abstract
Objectives: High workload, shift work, risk of disease, and mental workload caused by the possibility of transmission can create challenging and stressful situations for nurses. The present study aimed to assess the cognitive performance of nurses before and after working in COVID-19 wards to understand the potential effects.
Methods: A total of 250 nurses from hospitals in Ahvaz in 2020 who had more than two years of work experience and had not worked in departments in direct contact with COVID-19 patients were included in the study. The participants were asked to complete the cognitive ability assessment questionnaire before starting to work in COVID-19 departments and after two months of their work. The results before and after working in COVID-19 wards were compared using paired t-tests.
Results: The cognitive ability score after working in COVID-19 wards decreased significantly (mean difference±standard deviation: 23.92±12.00; P<0.001). The scores of all cognitive ability subscales except social cognition (mean difference±standard deviation: 3.03±2.43; P< 0.001) also decreased after working in COVID-19 wards.
Conclusion: Working in COVID-19 wards leads to a marked decrease in cognitive abilities of nurses. Given that the weakening of nurses' cognitive ability has a significant role in the quality of patient care measures, it is necessary to prioritize measures to improve their working conditions in order to improve cognitive abilities.
