About the author
Simon Bratt is a researcher and practitioner based at Liverpool Hope University, with more than a decade of frontline NHS and third-sector experience in prisons, psychiatric inpatient settings, hostels, A&E, and community substance use services.
His book A Philosophical Critique of Co-Existing Mental Health and Substance Use Challenges: Pain Comes First — Drugs Come Later (Palgrave Macmillan, 2026) argues that the failure of dual-diagnosis services is structural, not accidental, and offers the Layered Care Model as a practice-ready alternative.
He works with NHS Trusts, local authorities and voluntary-sector partners on translating the model into commissioning specifications, training programmes and service redesign — and speaks regularly to clinicians, commissioners and academic audiences across the UK and Europe.
