Richard Brumley, MD

Geriatric Medicine

Richard D. Brumley, MD, long active in promoting pain and symptom management for seriously ill patients, helped pioneer the practice of palliative medicine. Residency-trained in Family Medicine, he was among the first physicians in the U.S. to be board-certified in Hospice and Palliative Medicine. Presently he is the medical director for a community-based hospice agency in Orange County, California. Before that, he was the medical director of the Kaiser Permanente Hospice and Home Health Department for the TriCentral Service Area in Downey, California, as well as an associate clinical professor at the University of California, Irvine, School of Medicine, where he instructed Family Practice residents in hospice and home health services.

Between 1999 and 2000, Dr. Brumley, Dr. Enguidanos, and colleagues at Kaiser Permanente launched and evaluated one of the nation’s first home-based palliative care programs. Based on their positive findings, they conducted a randomized controlled trial of the program. In a now-widely cited journal article published in 2007, they reported that, compared to usual care, the home-based palliative care program improved satisfaction with care while decreasing medical service use and the cost of care.

Dr. Brumley now works with the Enguidanos research team to replicate the Kaiser model of home-based palliative care in primary care clinics that operate under accountable care organization contracts.
