Updated Information on the Annual Hospital-Acquired Condition Rate: 2011 and 2012

This document provides estimates of the national rate of hospital-acquired conditions (HACs) for the Partnership for Patients (PFP) program for calendar years 2011 and 2012. The methods used to compute this data are identical to those used to compute the 2010 baseline, as described in the document “Methods To Estimate the Baseline 2010 PFP National Hospital-Acquired Condition Rate,” available at http://www.ahrq.gov/professionals/quality-patient-safety/pfp/index.html. The annual estimates include a wide variety of adverse events, including the nine HACs selected for special focus as part of the PFP, as well as several other HACs. Collectively, 28 specific measures are used: 14 measures to generate rates for the 9 specific PFP HACs and 14 measures to generate a summary rate for “all other” HACs. Of the 28 measures, 21 are from the AHRQ/CMS Medicare Patient Safety Monitoring System (MPSMS), 6 are from the AHRQ Patient Safety Indicators (PSIs), and 1 is based on National Healthcare Safety Network (NHSN) data from the U.S. Centers for Disease Control and Prevention.

The data for 2011 and 2012 are shown in Table 1 below.
