Diabetes treatment among VA patients with comorbid serious mental illness.

Objective: Patients with serious mental illnesses, such as schizophrenia, bipolar disorder, and other psychoses, may be less likely to receive adequate care for chronic medical conditions than patients without serious mental illness. The quality and outcomes of diabetes care were compared in an observational study among patients with and without serious mental illness.

Methods: National data were studied for 36,546 individuals receiving care within the U.S. Department of Veterans Affairs (VA) health care system. Widely used diabetes quality-of-care measures and intermediate outcomes were compared for patients with diabetes and serious mental illness and age-matched patients with diabetes who did not have a serious mental illness. Patients' use of health services was also examined.

Results: During fiscal year 1998, patients with diabetes and serious mental illness were as likely as patients with diabetes alone to have their hemoglobin A1c, low-density lipoproteins (LDL), and cholesterol measured; both groups had comparable A1c, LDL, and cholesterol values. Patients with diabetes and serious mental illness had more outpatient visits, both primary care and specialty visits, and made more multiclinic visits, including visits to both primary care and mental health services on the same day.

Conclusions: In the VA, patients with diabetes and serious mental illness appear to receive diabetes care that is comparable with the care that other patients with diabetes receive, possibly because of increased levels of contact with the health system and the VA's integration of medical and mental health services.
