The investigators were inspired to do the current study by previous data suggesting that patients were less likely to be referred for a percutaneous transluminal coronary angioplasty (PTCA) if they had mental illness (approximately a 40% chance of PTCA) or substance abuse disorder (80%), compared with patients with neither mental illness nor substance abuse (nearly 100% referred), Dr. Mittal said.
They next plan to design an intervention aimed at decreasing bias and prejudice among health care providers toward people with serious mental illness, he said. Research also is needed to determine the extent to which stigmatized or negative views of mental illness might influence the quality of clinical care delivered.
The study was funded by the VA health care system research and development. Dr. Mittal reported having no financial disclosures.
