Project Details


The hospitalized adult population has increased in age and complexity, and medical issues have become more critical, creating the need for a comprehensive, robust and standardized national patient safety surveillance system.


In 2001 Qualidigm worked on a team with CMS leadership to create and design the Medicare Patient Safety Monitoring System (MPSMS), under the leadership of AHRQ and has been maintaining it for over ten years. MPSMS identifies the national rates of specific medical adverse events occurring within the hospitalized adult population, focusing on patient harm rather than medical error and the data is the backbone of the Department of Health and Human Services’ Partnership for Patients measurement.


MPSMS is now the largest and most robust national patient safety-focused data source of medical record-abstracted, clinical data available today. Data is available to researchers for discharges from 2002-2007 and 2009-2015. MPSMS data can be used for the identification, aggregation and trending of condition-specific and measure-specific harm experienced by adult hospitalized patients. Since 2004 it has sourced both the National Healthcare Quality and Disparities Reports, and the Partnership for Patients initiative.
