Mental health conditions confer considerable global disease burden in young adults, who are also the highest demographic to work shifts, and of whom 20% meet criteria for a sleep disorder. We aimed to establish the relationship between the combined effect of shift work and sleep disorders, and mental health. The Raine Study is the only longitudinal, population-based birth cohort in the world with gold-standard, Level 1 measurement of sleep (polysomnography, PSG) collected in early adulthood. Participants (aged 22y) underwent in-laboratory PSG and completed detailed sleep questionnaires. Multivariable adjusted robust linear regression models were conducted to explore associations with anxiety (GAD7) and depression (PHQ9), adjusted for sex, health comorbidities, and work hours/week. Data were from 660 employed young adults (27.3% shift workers). At least one clinically significant sleep disorder was present in 18% of shift workers (day, evening and night shifts) and 21% of non-shift workers (p = 0.51); 80% were undiagnosed. Scores for anxiety and depression were not different between shift and non-shift workers (p = 0.29 and p = 0.82); but were higher in those with a sleep disorder than those without (Md(IQR) anxiety: 7.0(4.0–10.0) vs 4.0(1.0–6.0)), and depression: (9.0(5.0–13.0) vs 4.0(2.0–6.0)). Considering evening and night shift workers only (i.e. excluding day shift workers) revealed an interaction between shift work and sleep disorder status for anxiety (p = 0.021), but not depression (p = 0.96), with anxiety scores being highest in those shift workers with a sleep disorder (Md(IQR) 8.5(4.0–12.2). We have shown that clinical sleep disorders are common in young workers and are largely undiagnosed. Measures of mental health do not appear be different between shift and non-shift workers. These findings indicate that the identification and treatment of clinical sleep disorders should be prioritised for young workers as these sleep disorders, rather than shift work per se, are associated with poorer mental health. These negative mental health effects appear to be greatest in those who work evening and/or night shift and have a sleep disorder.

Background: Nursing staff retention is an ongoing concern within pediatric hematology/oncology settings globally. Work-related stressors cause emotional burden, psychological distress, and burnout to which nurses respond by leaving their workplace. Consequently, workplace culture and functionality are negatively impacted, quality of care reduces, and potential harm to patients increases. This paper aims to identify the “most” influencing factors for intention to leave among pediatric hematology/oncology nurses. Methods: A systematic search was undertaken on 29 July 2021 across five electronic databases, Cumulative Index to Nursing and Allied Health Literature, Joanna Briggs Institute, MEDLINE, PubMed, and Web of Science, using MeSH and keywords related to pediatric hematology/oncology nurse retention. Results: The initial search yielded 283 articles. Following abstract and full-text review, nine articles met inclusion criteria. Across all studies, strong links between health service organizational factors (e.g., unit acuity and time constraints), clinician demographics (e.g., age, education, experience, and coping mechanisms), and nursing retention within pediatric hematology/oncology settings were observed. Direct patient care and long-term relationships with pediatric hematology/oncology patients were identified as the most frequent and intense stressors, while also presenting the most rewarding aspect of the nurse's work. Discussion: Clinician burnout and retention were found to be complex and multifaceted organizational and individual issues, which most importantly evolved from accumulative exposure to specialty-specific stressors. Interventions to prevent clinician burnout and improve staff retention, therefore, need to comprise individual and organizational level strategies specific to the healthcare context.
