Research Expertise & Professional Interests
Dr. Rosen is Professor of Health Policy and Management at Boston University School of Public Health and a researcher at the Center for Health Quality, Outcomes and Economic Research. She has conducted health services research projects involving the development and use of risk-adjustment models used to compare quality of care delivery in different settings: hospital, long-term care, and ambulatory care. Among her studies, she has evaluated the quality of care delivered to Medicare beneficiaries who received surgical procedures, for which a measure called “adverse events” became an important way to screen for potential instances of poor quality in this population. In long-term care, she developed a risk-adjustment model to predict decline in functional status among long-term care residents in VA settings. In the ambulatory setting, she evaluated case-mix models currently used for provider profiling, setting capitation rates, and quality assessment. These include the Adjusted Clinical Groups, the Diagnostic Cost Groups, and the Chronic Illness and Disability Payment System. She was a principal investigator of a project developing a psychiatric case-mix measure for the VA used to compare the care that facilities provide to patients with mental health disorders. More recently, Dr. Rosen has worked in the area of patient safety. She has examined the prevalence and incidence of Patient Safety Indicators, developed by AHRQ, in the VA, and has evaluated their construct and criterion validity. She has worked closely with AHRQ to improve the indicators. She is currently working on a study examining the patient safety culture of VA hospitals, as well as the changes in the quality and safety of care resulting from the resident work duty reform legislation. Dr. Rosen received her PhD from the University of Maryland in sociology.
