Outcomes research seeks to understand the end results of health care practices and interventions, including effects on quality of life and mortality. It links the care received to outcomes experienced to improve quality. Outcomes can be grouped as care-related, patient-related, or performance-related and are measured over short, intermediate, and long terms. Agencies like AHRQ and PCORI fund outcomes research to establish evidence-based practices and evaluate care quality. PCORI's mission includes increasing research quality and speeding evidence implementation to influence funded research.
