Patients, health care providers and medical insurers are among the groups who may have a question about medical care that cannot be answered with existing research. The Patient-Centered Outcomes Research Institute tackles such questions.  The institute's executive director, Joe Selby, MD, explains how the organization's research works to  involve and benefit the doctors, patientsm caregivers and others affected by a particular medical issue. He spoke in Syracuse recently at a FOCUS Greater Syracuse forum and also made time to join  Sharon Brangman, MD, for a "HealthLink on Air" interview. Brangman, the chair for the new department of geriatrics at Upstate, addresses local efforts to identify the concerns of aging patients and their families, such a  being able to remain in one's own home.
