The relationship between mental workload and job performance among Iranian nurses providing care to COVID-19 patients: A cross-sectional study.

Abstract

AimsTo evaluate the relationship between mental workload and job performance among nurses providing care to patients with COVID‐19, and to explain the factors predicting their performance.BackgroundThe increased workload of health care workers in the COVID‐19 pandemic affects their job performance, causes medical errors, contributes to patients’ mortality and is a major concern for all health care organisations in the world.MethodsThis cross‐sectional study recruited 139 nurses selected from the ICUs, infectious disease wards and emergency units of two hospitals in Iran. The NASA‐Task Load Index and Paterson's job performance questionnaire were used.ResultsMean scores of mental workload and job performance of the nurses were 67.14 ± 30.53 and 37.37 ± 7.36, respectively. A total of 71.95% and 96.4% of the nurses had high mental workload and job performance levels, respectively. The results indicated a weak positive correlation between mental workload and the mean score of job performance(r = .057). Unlike the mental demand (r = .175, p = .04) and temporal demand (r = .307, p < .001) that had a significant positive correlation with job performance, frustration had a significant negative correlation with job performance (r = −.183, p = .032). The following variables explained 33% of the variance of nurses’ job performance: age, gender, type of ward, working shift, experience of providing care to patients with COVID‐19 and frustration.ConclusionThe nurses’ mental workload increased during the COVID‐19 pandemic. Given the negative effect of mental workload on the nurses’ behaviour and performance, the rise in their job performance and its weak positive correlation with their mental workload should be further addressed.Implications for Nursing ManagementThe present study results support the need for focusing on implementing strategies such as providing social and psychological support to moderate mental workload and improve job performance of nurses who provide care to patients with COVID‐19.
