The AHRQ Hospital QI toolkit is designed to help your hospital understand the Quality Indicators (QI) from the Agency for Healthcare Research and Quality (AHRQ), and support your use of them to successfully improve quality and patient safety in your hospital. The toolkit is a general guide to using improvement methods, with a particular focus on the QI. It focuses on the 17 Patient Safety Indicators (PSI) and the 28 Inpatient Quality Indicators (IQI). Tools are organized in seven sections following a complete improvement process that includes setting priorities and plan for performance improvements on the QI, implementing improvement strategies, and sustaining improvements achieved. The toolkit has undergone a field test, evaluation, and revisions in response to feedback from six hospitals.
