March 4, 2010 updated by: Universitätsklinikum Hamburg-Eppendorf

Assertive Community Treatment (ACT) as Part of Integrated Care Versus Standard Care: a 12-month Trial in Patients With First- and Negatively Selected Multiple-episode Schizophrenia-spectrum Disorders Treated With Quetiapine IR

The study examined the 12-month effectiveness of continuous therapeutic assertive community treatment (ACT) as part of integrated care (IC) compared to standard care (SC) in a catchment area comparison design in patients with schizophrenia spectrum disorders (SSD) treated with quetiapine IR.

Conditions

Detailed Description

Two catchment areas in Hamburg, Germany with similar population size and health care structures were assigned to offer 12-month ACT (& IC; Department of Psychiatry and Psychotherapy, University Medical Center Hamburg-Eppendorf) or SC (Asklepios Hospital, Department of Psychiatry and Psychotherapy) to 120 first-episode and negatively selected multiple-episode patients with SSD. Primary outcome was the time to Service Disengagement. Secondary outcomes comprised medication non-adherence, improvements of symptoms, functioning, quality of life, satisfaction with care from patients and relatives perspectives, and service use data.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Standard care
Standard care comprised a treatment network consisting of open and closed inpatient wards, day-clinics, an outpatient centre, and eight private psychiatrists. Each patient was treated by a private psychiatrist or by a psychiatrist in the outpatient centre. Home visits were possible, but office visits were the general rule. Patients were allowed to use all treatment offers in the outpatient centre. Outside office hours, patients could refer themselves to the psychiatric hospital. Psychosocial treatments as supportive therapy, psychoeducation, psychotherapy, and family intervention were provided infrequently and in a less intensive and unsystematic way, and only in the minority of cases. This 'standard of care' definition is in accordance with other studies.
ACT was structured and implemented according to guidelines of the Assertive Community Treatment Association (ACTA). Team members were highly educated psychosis experts consisting of a consultant psychiatrist, a psychiatrist, two psychologists, and a nurse, all of which received training in cognitive behavioral (CBT), dynamic, and/or family psychotherapy. Study participants could use all treatment options within the integrated care program such as psychoeducation groups, social skills training, family groups, motivational addiction therapy, meta-cognitive training etc.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time to Service Disengagement
Time Frame: 12 months
The primary outcome of the study was the time to service disengagement (SD). This primary aim was chosen because the assertive approach of ACT is to prevent service disengagement3 and because service disengagement is a major predictor for relapse and thereby poor long-term outcome.16,17 Service disengagement was present, if a patient repeatedly refuses further treatment despite several attempts of reengagement (phone calls of patient and family in both treatment arms and potentially home visits in the ACT group).
12 months

Secondary Outcome Measures

Outcome Measure
Measure Description

Improvements of symptoms, functioning, quality of life, and satisfaction with care from patients and relatives perspectives
Time Frame: 12 months
Secondary outcomes comprised medication non-adherence, improvements of symptoms, functioning, quality of life, and satisfaction with care from patients and relatives perspectives.
