This study evaluated whether patients with severe and persistent mental illness (SPMI) who received coordinated co-located behavioral health and primary care services were more likely to improve health outcomes after 12 months compared to SPMI patients who receive only behavioral health services from the local mental health authority (LMHA) Tropical Texas Behavioral Health (TTBH).The study employed a randomized control trial (RCT) design where intervention participants receiving integrated behavioral health were compared to control participants receiving the usual care provided within an LMHA for SPMI patients. Patients were placed in each group using a randomized number process. Demographic and health outcome data were collected from intervention and control participants at baseline. Health outcome data was subsequently collected at 6-month and 12-month follow-up points. The primary outcome of interest was systolic blood pressure. Additional secondary outcomes of interest were diastolic blood pressure, HbA1c, BMI, total cholesterol, depressive symptoms, and life functioning. These outcomes were analyzed as continuous variables using linear regression with backward model selection. Longitudinal analyses were also conducted using a likelihood-based approach to general linear mixed models.The intervention and control groups were patients with an SPMI diagnosis over 18 years of age who were not receiving primary care services prior to enrollment and were eligible to receive behavioral health services from TTBH. The participants resided in Cameron or Hidalgo County and had one or more chronic conditions: hypertension (blood pressure of 140/90 mmHg or higher), poorly controlled diabetes (HbA1c over 8.5%), obesity (body mass index of 30.0 or higher), or hypercholesterolemia (total cholesterol level above 200).
