Preprints with The Lancet is a collaboration between The Lancet Group of journals and SSRN to facilitate the open sharing of preprints for early engagement, community comment, and collaboration. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early-stage research papers that have not been peer-reviewed. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. The findings should not be used for clinical or public health decision-making or presented without highlighting these facts. For more information, please see the FAQs.

Background: The Covid-19 pandemic has adversely affected population mental health.
Methods: Using electronic health records from 1714 UK general practices registered with the Clinical Practice Research Datalink we examined incidence and event rates of depression and anxiety disorders, self-harm, prescriptions for antidepressants and benzodiazepines and GP referrals to mental health services per 100,000 person-months, before, during and after the peak of the Covid-19 emergency. Analyses were stratified by gender, age group and practice-level Index of Multiple Deprivation quintile.
Findings: In April 2020, primary care-recorded incident depression reduced by 43·6% (95% CI 39·0% to 47·9%), anxiety disorders by 48·2% (CI 44·6% to 51·5%) and antidepressant prescribing by 36·2% (CI 33·7% to 38·6%) compared to expected rates based on prior trends. Reductions in first diagnoses of depression and anxiety disorders were particularly stark for working-age adults and patients registered at practices in more deprived areas. Self-harm incidence was 38·5% (CI 35·7% to 41·3%) lower than expected in April 2020. Total self-harm contacts fell by 28·2% (CI 25·5% to 30·8%). Rates of both incident and any self-harm remained around thirty percent lower than expected up to June 2020.
Interpretation: Our findings reveal a stark treatment gap that was greater for first diagnoses of depression and anxiety disorders in working age adults, for practice populations in deprived areas, and for self-harm. Consequences could include more patients subsequently presenting with greater acuity and severity of mental illness and rising rates of non-fatal self-harm and suicide.
