Dr. Perloff is a Scientist and Deputy Director at the Institute for Healthcare Systems within the Schneider Institutes for Healthcare Policy. Dr. Perloff has over fifteen years of experience in evaluation and health services research. She is currently involved in a number of projects related to episodes of care, including one project that will use episodes to compare the cost and quality of nurse practitioner versus physician provided primary care. She is also the project manager on Dr. Christopher Tompkins’s 4-year project to develop a public sector episode grouper for Medicare. This ground breaking effort will results in a comprehensive, patient centered system with over 200 episodes that can be used to assess quality, cost, and efficiency for provider profiling and payment reform. Dr. Perloff recently completed a study for CMS to develop a methodology to determining the value of Medicare Advantage plans from a consumer perspective. Dr. Perloff also recently evaluated a SAMHSA funded intensive case management program for homeless adults in Hyannis, Massachusetts. This mixed methods study was focused on identifying health care cost offsets as a result of pro-active, coordinated medial, behavioral and social services. Dr. Perloff’s current work involves analysis of large claims data sets, often in a time series context.
