Sleep disorders, depression and anxiety are associated with adverse safety outcomes in healthcare workers: A prospective cohort study

Abstract

The objective of the study was to determine if sleep disorder, depression or anxiety screening status was associated with safety outcomes in a diverse population of hospital workers. A sample of shift workers at four hospitals participated in a prospective cohort study. Participants were screened for five sleep disorders, depression and anxiety at baseline, then completed prospective monthly surveys for the next 6 months to capture motor vehicle crashes, near-miss crashes, occupational exposures and medical errors. We tested the associations between sleep disorders, depression and anxiety and adverse safety outcomes using incidence rate ratios adjusted for potentially confounding factors in a multivariable negative binomial regression model. Of the 416 hospital workers who participated, two in five (40.9%) screened positive for a sleep disorder and 21.6% screened positive for depression or anxiety. After multivariable adjustment, screening positive for a sleep disorder was associated with 83% increased incidence of adverse safety outcomes. Screening positive for depression or anxiety increased the risk by 63%. Sleep disorders and mood disorders were independently associated with adverse outcomes and contributed additively to risk. Our findings suggest that screening for sleep disorders and mental health screening can help identify individuals who are vulnerable to adverse safety outcomes. Future research should evaluate sleep and mental health screening, evaluation and treatment programmes that may improve safety.

Mental health impacts among health workers during COVID-19 in a low resource setting: a cross-sectional survey from Nepal

“…The increased risk of infection and stressful environment might have contributed to higher mental health impacts among health workers in China than in Nepal [ 5 , 8 , 31 ]. Mental health outcomes among health workers affect their work performance and to address this, specialised mental health services are required [ 8 , 32 , 33 ]. The higher perceived risk and having to stay in quarantine during the epidemic might not just result in short term impacts but also lead to long term mental health consequences among health workers [ 34 – 36 ].…”

Nurses' mental health and patient safety: An extension of the Job Demands–Resources model

“…Moreover, mental health problems are an important cause of workplace illness (Roelen et al, ). Studies have shown that nurses' mental health problems impact the amount of sick leave taken, the willingness to leave and patient safety (Hilton, Scuffham, Sheridan, Cleary, & Whiteford, ; Weaver et al, ). Patient safety comprises an important part of management responsibilities (Li et al, ).…”

“…Work engagement mediated the relationship between job characteristics and intention to leave the profession (Wan, Li, Zhou, & Shang, ). Moreover, health care workers' depression and anxiety were linked to poor patient safety outcomes (Weaver et al, ). Thus, we form the following hypotheses:…”
