Assertive Community Treatment:
An integrated MH community care model?
Tom Burns Professor of Social Psychiatry
University of OxfordUK
16 August – 5 September 1807
Second battle of Copenhagen
British navy bombards Copenhagen
Walls of the asylum breached and patients escape
Danish community psychiatry begins
Early developments
• Outreach an early feature of UK psychiatry– 1948 NHS consultants’ ‘domiciliary visits’– 1953 First CPNs in Warlingham Park Hospital– 1959 MHA shaped sectorisation and outreach
• Must offer OP follow up of compulsory patients• Social workers involved in admission and support
• ‘Sector/Secteur’ model developed – France and UK in 1960s
Community Mental Health Teams (CMHTs)
• Multidisciplinary CMHTs arise to meet complex needs – Medically led
• CMHTs with CPNs the norm by late 1970s– Social workers, psychologists, occupational
therapists• Responsible for inpatient and community care• Referrals from Primary Care (liaison)
Evidence Based Mental Health Care
• EBM in 1970s
• Evidence (RCTs) > experience and authority
• Internationalization of evidence
• Stein and Test (1980) starting pistol for Mental Health Services Research
PACT - Stein & Test 1980• Project for Assertive Community Treatment• 126 psychotic patients in RCT of:
– Intensive case management (ACT)– Treatment as usual
• Results:• Hospitalisation Reduced >70%• Social Functioning Improved• Symptoms Same/Improved• Employment Enhanced• Costs Equivocal
PACT Clinical Practice• Low case loads 1:10• Frequent contact (weekly to daily)• In vivo (outreach to home and neighborhood)• Daily team meetings • Multidisciplinary work ‘whole team approach’• Flexibility, crisis stabilization, available 24/7• Not time limited
• Emphasis on medication• Emphasis on survival skills and circumstances
–Accommodation, food, money–Social functioning – leisure, work and substance abuse

ACT research takes off
• Over 50 studies in Meuser’s 1998 review– Of which >30 ACT like– Mueser KT, Bond GR, Drake RE, Resnick SG. Models of community
care for severe mental illness: a review of research on case management. Schizophrenia Bulletin 1998;24(1):37-74.
• Over 90 studies in Catty 2002 review– Of which >60 ACT like– Catty J, Burns T, Knapp M, Watt H, Wright C, Henderson J et al. Home
treatment for mental health problems: A systematic review.
Psychological Medicine 2002;32:383-401

The intellectual puzzle
• No European study has replicated these findings
• UK700 and PRiSM showed no difference
• This paradox has helped us identify what is needed for effective community care
“When the facts change, I change my opinion. What, sir, do you do?”
John Maynard Keynes, economist

Two explanations
• Current European (UK) care already achieved low bed occupancy
• UK experimental services did not successfully replicate ACT intensity and skill – ‘poor model fidelity’

Conclusion: Effective ingredients in community mental health care
• Home visiting• Integrated psychiatrist• Combined health and social care• Multidisciplinarity• Small caseloads (1:20)• Team organisation: not specifics of
staffing
What does not seem necessary?
• Tiny caseloads– ultra-high intensity of contact
• Highly specialized staff– Vocational rehab, drug staff etc
• 24 hour availability• Whole team approach
What have we learnt from ACT?
• Fixed caseloads– Probably 20- 25
• Regularity of meetings• Zoning
– FACT (Functional ACT)• Red – frequent visits• Yellow – routine visits• Green – open to team
Current controversies
• Continuity of care– Separate inpatient and outpatient teams– Highly specialized teams
• Crisis / early intervention / assessment etc.
• Balancing of specialist and generic mental health skills and responsibilities
• Coercion , paternalism, confidentiality
