Under contract to CMS, Dr. Horwitz led the development of the all-condition 30-day readmission quality measure for hospitals that is endorsed by the National Quality Forum and is now publicly reported. At NYU, Dr. Horwitz is the PI of the NYU Patient Imaging Quality and Safety Laboratory (funded by AHRQ) and of the Greater New York City Practice Transformation Network (funded by CMS).
