Assertive community-based treatment program in a day care center in Athens, Greece: Results from a retrospective...

Over recent decades, a number of outpatient care models, including highly specialized community services such as Assertive Community Treatment (ACT), have been developed to treat patients with Severe Mental Illness (SMI). ACT has been rigorously evaluated for its effectiveness and is suggested as the most clinically effective treatment for people with SMI.

The present retrospective cohort study sought to investigate the efficacy of an Assertive Community-based Treatment Program, based on the core principles of ACT, with an emphasis on psychiatric hospitalizations before and after treatment initiation. All individuals referred to the Assertive Community-based Treatment Program at the 'Franco Basaglia' Day Care Center for Psychosocial Interventions during a 7-year period (2013-2020) were included in the study. A 41.9% of patients had been hospitalized for mental illness 2 years before treatment initiation.

The findings show that ACT reduced the odds of admission 1 year after patients received the intervention, as well as a statistically significant decrease in the number of admissions compared to the year before treatment. Moreover, high levels of functioning at baseline were related to lower odds of hospitalization during the ACT intervention, suggesting that functioning may be an early prognostic factor for hospitalization among patients with SMI.

Our results stress the need for strengthening community-based mental health services in Greece and developing policies that support the broader implementation of ACT and improve continuity of care. Further research is needed to assess the long-term efficacy of ACT teams in Greece and to inform national mental health strategies regarding its accurate application across populations and settings.
