Outcomes research evaluates the impact of health care on the health outcomes of patients and populations.
It may also include an evaluation of economic impacts linked to health outcomes, such as cost effectiveness and cost utility. Outcomes research emphasizes health problems, or disease-oriented evaluations of care, delivered in general, real-world settings; multidisciplinary teams; and a wide range of outcomes, including mortality, morbidity, functional status, mental well-being, and other aspects of health-related quality of life.
