Manchester Dual Diagnosis Liaison Service

Specialist advice and consultancy is available to all practitioners within mental health and substance misuse service to support their work with services users who are Manchester residents and have a dual diagnosis. This can be delivered on trust premises or in community venues. It can be provided to practitioners alone or alternatively to practitioners with their client present (interactive 3-way session).

The purpose of the Manchester Dual Diagnosis Service is to:

  • Provide advice and consultancy to staff within mental health and substance misuse services to support their work with service users who experience both mental health problems and substance use problems.
  • Deliver core skills and advanced skills training to staff within their mental health and substance misuse services to ensure practitioners are competent in the skills required to work with services users with a dual diagnosis
  • Promote effective multi-agency work between mental health services and substance misuse services in Manchester.

What is Dual Diagnosis?

What is dual diagnosis?

  • Dual diagnosis is a term denoting co-existing mental health problems and alcohol or drug misuse
  • It is sometimes referred to as Co-occurring Mental Health, Alcohol and Drugs (COMHAD)
  • It is estimated that 30% to 50% of people with a serious mental illness, also have a co-existing alcohol/drug condition
  • In alcohol and drug services, it is estimated between 70% to 80% have difficulties in relation to their mental health

Why does it matter?

  • Poorer quality of life and accommodation and work problems
  • Increased physical health morbidity and mortality
  • Increased rates of hospital admission, relapse, suicide and violence
  • Increased risk of falling between service specifications thus reducing access to care and support
  • Staff supporting people can experience their own difficulties navigating services and require support with coordination of services
