Dr. Allison Lipitz-Snyderman is a health services researcher focused on quality measurement in cancer care. Her research falls into three primary topic areas: (1) assessment of variation in practice patterns and outcomes, (2) examination of harm due to medical care and the overuse of medical care, and (3) evaluation of quality improvement activities. Dr. Lipitz-Snyderman received funding from the National Institute for Health Care Management (NIHCM) Foundation to assess the extent of physician-driven variation in the use of services that tend to be overused. She is currently building on this work to examine hospital-level variation in outcomes of cancer care. Dr. Lipitz-Snyderman has worked to assess the burden of potentially preventable harm that occurs during cancer treatment. She led a project to develop an oncology-specific ‘trigger tool’ to detect harm from medical records for patients with cancer across the care continuum, funded by the United Hospital Fund. Prior work included an evaluation of a multifaceted intervention, the Michigan Keystone ICU Project, aimed to reduce device-related bloodstream infections across the state of Michigan, on the outcomes of mortality and length of stay. Dr. Lipitz-Snyderman is a member of the MSK Center for Health Policy and Outcomes.
