Is working in the emergency department a risk factor for sleep disorders for healthcare workers?

OBJECTIVE

This study aims to investigate the relationship between work-related stress and sleep disorders in healthcare personnel working in emergency department and in other departments.

MATERIAL AND METHODS

This cross-sectional study included 34 emergency department healthcare personnel (emergency group [EG]) and 35 healthcare personnel working in other departments (non-emergency group [NEG]) and was conducted between November 10, 2019 and March 1, 2020. All participants were administered the following questionnaires: work-related strain inventory (WRSI), Epworth sleepiness scale (ESS), Berlin questionnaire, insomnia severity index (ISI), Pittsburgh sleep quality index (PSQI), Beck depression inventory (BDI), and Beck anxiety inventory (BAI).

RESULTS

While the mean WRSI score of EG was 39.53±7.77, the mean WRSI score of NEG was 30.06±7.26 (t=5.236, p<0.001). According to PSQI, 79.4% of EG and 57.1% of NEG were found to have poor sleep quality (X=3.938, df=1, =0.047). Median PSQI overall score was 12 (IQR 25th-75th percentiles: 10-14) in EG, and 7 (IQR 25th-75th percentiles: 4-9) in NEG (U=285.5, <0.001). While the mean anxiety score of EG was 13.35±5.70, the mean anxiety score of NEG was 9.06±6.00 (t=3.046, =0.003). Median depression score was 12 (IQR 25th-75th percentiles: 10-16) in EG, and was 8 (IQR 25th-75th percentiles: 4-12) in NEG (U=354, =0.004). A significant positive correlation was found between work-related strain scores and sleep quality, sleepiness, and insomnia severity scores (r=0.541, <0.001; r=0.310, =0.010; r=0.357, =0.004; respectively).

CONCLUSION

It was determined that healthcare personnel working in the emergency department were at higher risk of developing sleep disorders compared to healthcare personnel working in other departments and that there was a significant relationship between sleep disorders and work-related stress.
