Early Health Impacts of a Primary Care Consultation Model for People Served by Assertive Community Treatment teams

The cardiometabolic health outcomes and life expectancy of people living with serious mental illness (SMI) continue to significantly flag behind that of the general population. This study explores the possibility of using the evidence-based Assertive Community Treatment (ACT) model and infrastructure to increase access to primary care and improve cardiometabolic outcomes of people with SMI. Four ACT teams in a large urban area received the services of a primary care consultant who was co-located at a Federally Qualified Health Center (FQHC), met regularly with ACT team clinicians to review a cardiometabolic registry of participants, and engaged participants in primary care services. Health screening rates, primary care utilization, and cardiometabolic outcomes-body mass index, blood pressure, hemoglobin A1c, cholesterol, and tobacco smoking status-were monitored over the course of a year. The efficacy of this integrated care model was also explored through focus groups with ACT team staff and participants. Significant improvements in screening rates were found for the ACT teams that received this integrated care intervention; however, only modest improvements in cardiometabolic outcomes were found. Future longitudinal, multi-site studies are needed to fully determine the impact of integrated care models on the physical health outcomes of this vulnerable population.
