Description of Research Expertise
I am a practicing anesthesiologist and health services researcher. My research seeks to understand the health-system level determinants of long-term outcomes of surgery and acute care among older adults U.S., with an emphasis on examining how variations in care delivered in discrete settings—such as acute-care hospitals and skilled nursing facilities—each ultimately influence the end results of care. In particular, my work focuses on examining variations the care and outcomes of older adults with acute hip fracture, a common and morbid injury that occurs over 300,000 each year in the U.S. and requires the coordination of surgical, anesthetic, medical, rehabilitative, nursing and social work services across a range of care settings. To date, my research output has employed a range of methodologies to obtain a multifaceted view of current patterns of hip fracture care and outcomes. These methodologies have included observational studies using administrative databases, meta-analyses and a telephone- and web-based survey of health care administrators. Additionally, I have conduced qualitative research incorporating interviews of physicians and analyses of documentary evidence. This work has studied the social and cultural influences underlying current patterns of utilization of surgical care services in the U.S. as a means of understanding the mechanisms underlying institutional variations in performance and health care outcomes.
