MIDAS: A new service for the mentally ill with comorbid drug and alcohol misuse

Abstract

Aims and method: To describe the work and patient characteristics of one of the first combined mental illness and drug and alcohol services (MIDAS) in the UK. We examined MIDAS as an assertive community service, for individuals receiving long-term community care. We selected the case files of the first 80 patients accepted over a 10-month period and examined variables including demographic details, diagnosis, associated substance use and length of engagement with the service. Results: Our findings show that there was no relationship between responders to the service and basic demographic data. Patients with bipolar affective disorders and personality disorders were more likely to use the service than patients with unipolar disorder or schizophrenia. Despite the use of an assertive service, there was difficulty engaging patients with schizophrenia and comorbid drug use. These same patients also had a high level of criminal convictions as well as a trend towards using alcohol and cannabis as their main substances of misuse. At 18 months 38% of patients had failed to remain engaged with the service. Clinical implications: This specialist type of service may be more useful than other services in engaging patients with comorbidity. Systematic research is required in the UK to explore the effectiveness of this type of new service. More innovative resources need to be identified to specifically deal with patients with severe mental illness and comorbid substance use.
