1. Introduction to Dual Diagnosis in Assertive Outreach

2. Objectives Define and understand the term “dual diagnosis” Be aware of the prevalence rates in assertive outreach Be able to list associated consequences of having combined mental health and substance use problems. Policies relevant to dual diagnosis within AOT

3. Dual Diagnosis Capabilities Role Legitimacy: Recognise and accept that working with people with dual diagnosis is a routine part of ones role Dual Diagnosis Capability 1 level 2 Acceptance of the Uniqueness of Each Individual: Be able to accept the person as a unique individual and respect their choices and lifestyle. Dual Diagnosis Capability 3 level 2

4. Definitions The term “dual diagnosis” is generally applied to people who have two disorders Combined mental health and substance use problems More than “dual problems”- likely to have complex health and social needs Wide range of people with varying degrees of need- need individualised treatment

5. Table 1 Serious mental illness E.g. someone with bipolar affective disorder who smokes cannabis twice per week E.g. Someone with schizophrenia and alcohol dependence Minor substance use E.G. Someone with anxiety who snorts cocaine occasionally Minor mental illness Severe substance use E.g. someone with heroin dependency and depression

6. “Mainstreaming” DH (2002) Good Practice Guide: Doesn’t advocate a separate specialist service for dual diagnosis Mental health services should take primary responsibility for those with serious mental health problems (like schizophrenia) and substance use AOT likely to provide care for those with dual diagnosis as typically hard to engage and chaotic users of services Substance use services should take primary responsibility for those with primary substance problems and common mental health problems (anxiety, depression) However mental health and substance use services should work together and support each other

7. Discussion 1 What have been your experiences of working with people with dual diagnosis within AOT? Think about issues concerning: –the individual –the carer –Yourselves –the AOT

8. UK Dual Diagnosis Prevalence Studies Menezes (1996) Inner London MH services 36% (1 year) Cantwell (1999) Nottingham first episode psychosis 37% (1 year) Weaver (2001) Inner London Community mental health and substance use services 24% (recent-last 30 days) Phillips (2003) Inner London (in-patient setting) 49% (last 6 months) Graham (2001) Birmingham (MH and SU services) identified 24% SMI problems with drugs/alcohol –More likely to be using at impairment/dependence level –More likely to be in AOT (26-45% of case-loads depending on location) –Over representation of African-caribbean in AOT (46%) Priebe et al (2003) London AOT 29% misused at least 1 type of substance(last 6 months) –20% misused/dependent on drugs –16% misused/ dependent on alcohol –Most common street drug was cannabis (23%), followed by cocaine (7.4%)

9. Consequences of co-morbidity Increased likelihood of self-harm and violence Poor physical health (including HIV, hep B and C) Frequent relapse and re-hospitalisation Higher rates compulsory detention Forensic mental health care and criminal justice system Higher overall risk of untoward incidents Difficulty getting access to appropriate aftercare Poor medication adherence Family problems Homelessness Higher overall service costs Higher levels of social exclusion

10. Profile Of Dual Diagnosis in AOT (London) (Fakoury, et al 2006) White* Single Young Unemployed Homelessness Poor educational attainment Living alone Contacts with criminal justice system * (Graham et al (2001) found over-representation of people of African- Caribbean origin in Birmingham, UK)

11. Most Commonly used substances 1.Alcohol 2.Cannabis 3.Cocaine More rarely: –amphetamines –Opiates –Hallucinogens (LSD, magic Mushrooms) –Solvents and glue –Over the counter meds (anti-histamines) –Abuse of prescribed drugs (benzodiazepines, anti-cholinergics) *NB geographical location will affect patterns- need to know your local drugs scene.

12. Patterns of use Use with impairment (DSMIV “abuse”) rather than dependence Poly-substance use common

13. Diagnostic Criteria for Substance use Problems (DSM IV)

14. Substance Use Substances that alter level of consciousness and/or perception Levels of use: –Experimental (occassional- not always safe!) –Recreational (regular, but within safe limits) –Bingeing/ dangerous use (high intensity over short length of time) –dependence (increased tolerance and withdrawals if stop)

15. Misuse of Drugs act 1971 Class A- heroin, cocaine, ecstasy, LSD, anything prepared for IV use, cannabis oil Class B- amphetamines, oral opiates (DF118) Class C- benzodiazepines, cannabis Classification refers to perceived harm, and severe penalties for possession trafficking and supply. A carries highest penalties

16. Exercise 1 Ask yourself these questions: What attitudes do I have about people who use drugs and people who use alcohol? Where did these attitudes come from? (Parents, school, media, religious beliefs etc) How might these attitudes affect how I work with people with substance use problems?

17. Exercise 2: Why Use? Why do I (did I) smoke cigarettes; drink caffeinated drinks e.g. coffee, tea, cola; drink alcohol? Make a list of the reasons why, the benefits, and if there are any, some of the less good aspects of these habits. why do people with mental health problems use drugs and alcohol? Make a list of the reasons that you are aware of from what service users have told you, or assumptions that you have made.

18. Reasons for use To feel euphoric or feel nothing To feel more confident To work longer hours or enhance performance To belong to a social group (peer pressure) To kill time (alleviate boredom) To alleviate physical pain and other health problems Because it is a habit To satisfy cravings and avoid withdrawal symptoms For weight loss To experience an altered state of consciousness To unwind after a stressful day

19. Alcohol Alcohol is a widely used, legal and socially acceptable drug. It is taken orally. It is a central nervous system depressant Dangerous drug; accidents whilst intoxicated, overdose choking on vomit. Alcohol related to 40% of violent offences;44 per cent for domestic violence and 53 per cent for violence committed against a stranger [British Crime Survey, 2000].

20. Alcohol 2 Safe levels <3 units per day Males up to 21 units/week; females up to 14 units/week Unit = volume x ABV/1000 (250mls wine 13%ABV/1000=3.25 units Physical dependency- ↑tolerance and withdrawals Signs of withdrawal: nausea, vomiting, sweating, high temperature, hypertension, anxiety, sleeplessness, restlessness, and sometimes hallucinations, epileptic fits. Withdrawals need immediate medical attention and treatment as can be life-threatening. Never advise abrupt cessation of heavy drinking without treatment!!

21. Cannabis Cannabis is a sedative and hallucinogenic drug produced from the leaves and buds of the cannabis sativa plant. Most commonly used illegal drug.

Effects: relaxation, increased senses, slowing of thoughts, time seems to pass more slowly, sometimes mild hallucinogenic effects. Risks: mouth and lung cancer, exacerbate other lung conditions, increases likelihood of psychosis, road traffic accidents whilst driving under the influence.

22. Cocaine and Crack Cocaine Stimulant drugs Legality- class A drugs What do they look like: cocaine is a white crystalline powder, and crack is white or off-white crystalline rocks How taken: Cocaine may be taken orally, snorted, inhaled, or injected.

Withdrawals: gooseflesh, shivering, profuse sweating, feeling feverish, aching limbs, yawning, runny eyes, runny nose, gastrointestinal disturbances such as stomach cramps, nausea, vomiting and diarrhoea. Risks: overdose, injecting related problems, BBVs, accidents

24. Other Drugs: solvents, ecstasy, LSD, amphetamines

25. Other Drugs Hallucinogens: LSD, magic mushrooms –Distort perceptions for several hours –“psychotic” trip –Can be terrifying “bad trip” Ecstasy –Stimulant and mildly hallucinogenic –Feelings of empathy, energy –Depression and short term memory problems –Death as a result of kidney failure Amphetamines –Effects like cocaine –Paranoia and aggression Solvents and gases –Sniffed, inhaled –Intoxication –Risk of instant death, brain damage, accidents Caffeine- –“Red Bull”; coffee; cola drinks –Stimulants, irritability, aggression, paranoia OTC- over the counter (cough linctus, anti-histamines etc) Prescription drugs- benzodiazepines, anti-cholinergics
