The document discusses quality indicators (QIs) created by the Agency for Healthcare Research and Quality to measure and track healthcare quality. It explains that QIs have four standardized parts: pediatric quality indicators that focus on pediatric care quality and preventable hospital admissions, prevention quality indicators that represent rates of conditions that could be treated in outpatient settings, inpatient quality indicators that relate to utilization and efficiency of inpatient care, and outcomes quality indicators that focus on mortality rates after procedures and surgeries. The indicators are evidence-based measures that can identify issues and focus on preventive healthcare using readily available administrative data.
