Abstract

Background: Improved management of mental illness and substance misuse comorbidity is a National Health Service priority, but little is known about its prevalence and current management. Aims: To measure the prevalence of comorbidity among patients of community mental health teams (CMHTs) and substance misuse services, and to assess the potential for joint management. Method: Cross-sectional prevalence survey in four urban UK centres. Results: Of CMHT patients, 44% (95% CI 38.1-49.9) reported past-year problem drug use and/or harmful alcohol use; 75% (95% CI 68.2-80.2) of drug service and 85% of alcohol service patients (95% CI 74.2-931) had a past-year psychiatric disorder. Most comorbidity patients appear ineligible for cross-referral between services. Large proportions are not identified by services and receive no specialist intervention. Conclusions: Comorbidity is highly prevalent in CMHT, drug and alcohol treatment populations, but may be difficult to manage by cross-referral psychiatric and substance misuse services as currently configured and resourced.

  • Up to 86% of individuals who use substances also meet criteria for common mental health disorders.

    “Poor emotional regulation and avoidance are closely intertwined with mental health difficulties, and up to 86% of individuals who use substances also meet criteria for common mental health disorders (Weaver et al., 2003).”

    From “I don’t want to take buprenorphine for the rest of my life”: Acceptance and Commitment Therapy for a Client Struggling to Reduce Low-Dose Buprenorphine (a Hermeneutic Single-Case Efficacy Design) (2023) · cites this paper as Weaver et al., 2003

    Table 3 (prevalence of comorbidity in drug and alcohol services; page unavailable) reports a psychiatric disorder in 53 of 62 alcohol-service patients (85%) and 161 of 216 drug-service patients (75%). This supports a high rate of comorbidity, but not the stated 86% or its extension to all individuals who use substances. The table counts any psychiatric disorder, including psychotic and personality disorders, rather than only common mental health disorders. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
