6. Matching Support Intensity: ICM vs ACT
In complex multimorbidity, the intensity of support matters.
Intensive Case Management (ICM)

Moderate caseload

Coordination-focused

Linkage to services

Suitable for moderate complexity

Assertive Community Treatment (ACT)

Small caseload

Multidisciplinary team

Direct service provision

Psychiatric capacity

Crisis response

Suitable for severe and persistent mental illness with instability

Choosing ICM when ACT is required increases risk of relapse and hospitalisation.
Choosing ACT unnecessarily may reduce resource efficiency.
Clinical judgment must align intensity with complexity.
