A Reverse Colocated Integrated Care Model Intervention among Persons with Severe Persistent Mental Illness at the U.S.-Mexico Border: A Randomized Controlled Trial Protocol

Abstract

Persons with severe persistent mental illness (SPMI)—which include individuals with schizophrenia, bipolar disorder, and mood disorders such as major depression—are at high risk for poor health outcomes and premature death. Persons with SPMI are largely absent from research evaluating innovative health care models due to recruitment and retention barriers. This paper presents the protocol for a randomized control trial testing a reverse colocated integrated care model in an SPMI population receiving care at a mental health clinic at the U.S.-Mexico border. The study employs a randomized control trial design to determine whether reverse colocated integrated care improves physical and mental health of persons with SPMI. Participants will be randomized to receive the integrated primary care intervention or usual care (behavioral health only). All study participants will complete baseline, 6-, and 12-month assessments. Study outcomes included blood pressure, HbA1c, cholesterol, body mass index, depression, and adult functioning. Despite challenges in recruiting and retaining SPMI patients, co-locating primary care services within a local mental health authority has the potential to improve health and reduce health disparities experienced by persons with SPMI. The study will determine the impacts of this colocated integrated care model among SPMI patients in a socio-economically disadvantaged region.Clinical Trials.gov Identifier: NCT03881657.
