Long-term Links Between Alcohol Use, Workplace Stress, and Mental Health in UK Healthcare Staff During COVID-19

Overview

This longitudinal UK-REACH study examined healthcare workers' mental health and alcohol consumption during the COVID-19 pandemic. Findings indicate that increased frequency of alcohol use, occupational stressors, COVID-19 related stress, and workplace discrimination were associated with worsened symptoms of common mental disorders (CMD).

Background

The COVID-19 pandemic has adversely affected mental health globally, with healthcare workers (HCWs) particularly vulnerable due to occupational stress and trauma exposure. Mental health problems often co-occur with at-risk alcohol use, which may be used as self-medication or exacerbate symptoms. Prior to and during the pandemic, HCWs faced increased psychological strain, with women and nurses disproportionately affected. Despite evidence of elevated at-risk drinking among HCWs, associations between alcohol use and CMD during the pandemic have not been thoroughly studied.

Data Highlights

The UK-REACH cohort included 15,119 baseline respondents, with 5,632 and 6,535 completing 6- and 10-month follow-ups respectively. Participants completed validated screening tools for anxiety, depression, and PTSD at three time points during the pandemic. The cohort was ethnically diverse and representative of the NHS workforce in age and sex distribution. Data captured alcohol use frequency, occupational stressors, COVID-19 related stressors, and experiences of discrimination.

Key Findings

• More frequent alcohol use over time was associated with increased symptoms of common mental disorders (CMD) among healthcare workers.
• Occupational stressors related to psychological and physical safety, including access to personal protective equipment, correlated with worsened CMD symptoms.
• COVID-19 related stressors such as previous infection and bereavement were linked to increased CMD symptoms.
• Workplace discrimination was significantly associated with higher CMD symptomatology.
• The interaction between occupational stressors and alcohol use frequency suggested that alcohol's impact on CMD symptoms was stronger among those experiencing greater workplace stress.

Clinical Implications

Healthcare organizations should prioritize reducing occupational stressors and ensuring psychological and physical safety to mitigate mental health deterioration among staff. Screening for at-risk alcohol use and providing targeted support may help address co-occurring CMD symptoms. Addressing workplace discrimination is also critical to improving mental well-being in healthcare settings during and beyond pandemic conditions.

Conclusion

This study highlights the complex interplay between alcohol consumption, workplace stressors, and mental health among UK healthcare workers during the COVID-19 pandemic. Interventions addressing these factors are essential to support a resilient healthcare workforce.
