IMD = Index of Multiple Deprivation. LTCs = long-term conditions. Mental–physical multimorbidity = ≥2 LTCs where ≥1 mental health LTC and ≥1 physical health LTC are recorded. Multimorbidity 2+ = ≥2 LTCs. Multimorbidity 3+ = ≥3 LTCs. Multimorbidity 3+ from 3+ = ≥3 LTCs from ≥3 International Classification of Diseases, 10th revision chapters.
