Study design: Observational Study
Abstract: BACKGROUND: Ethnic inequalities in compulsory psychiatric hospital detentions are well-documented in the UK and internationally. It is unknown how UK coronavirus disease 2019 (COVID-19) lockdown measures, which led to restrictions in public movement, gatherings, in-person health service delivery and changes to police powers, further impacted inequalities. AIMS: In this study, we assessed whether national lockdown measures impacted ethnic inequalities in voluntary and compulsory psychiatric hospital admissions during the COVID-19 pandemic. METHOD: Daily counts of admissions and detentions to psychiatric hospitals were extracted from a large population-level sample of secondary mental health service users in South East London. Changes during two COVID-19 lockdown periods, over 2020-2021, were compared with pre-pandemic periods (2016-2019) with the use of a regression discontinuity in time design to assess ethnic inequalities in voluntary and compulsory mental health admissions. RESULTS: Compared to the pre-pandemic reference (2016-2019), after adjusting for seasonal and weekly trends, overall admissions to mental health units dropped during the first COVID-19 lockdown (incidence rate ratio (IRR) 0.87 (95% CI: 0.75-1.00)), but compulsory detentions rose (IRR 1.25 (1.05-1.54)). This was mostly due to higher compulsory detentions in the Black Caribbean group (IRR 1.54 (1.08-2.19)). During the second COVID-19 lockdown, whereas total daily admissions remained similar to the pre-pandemic reference (IRR 1.03 (0.92-1.15)), total new daily detentions was elevated (IRR 1.28 (1.11-1.49)), specifically in Black Caribbean (IRR 1.53 (1.14-2.06)) and Black African (IRR 1.57 (1.06-2.34)) groups. CONCLUSIONS: COVID-19 lockdown measures exacerbated pre-existing ethnic inequalities in compulsory psychiatric detention, particularly for those from Black Caribbean and Black African backgrounds. There is a need to address ethnic inequalities in compulsory psychiatric detentions and attend to exacerbations of pre-existing inequalities during health emergencies like the COVID-19 pandemic. This cannot be achieved without addressing systemic racism within criminal justice and healthcare systems and tackling inequalities in wider social and economic determinants of mental health.
