Health outcomes research

Outcomes research is a branch of public health research, which studies the end results () of the structure and processes of the health care system on the health and well-being of patients and populations. According to one medical outcomes and guidelines source book - 1996, Outcomes research includes health services research that focuses on identifying variations in medical procedures and associated health outcomes. Though listed as a synonym for the National Library of Medicine MeSH term "Outcome Assessment (Health Care)", outcomes research may refer to both health services research and healthcare outcomes assessment, which aims at Health technology assessment, decision making, and policy analysis through systematic evaluation of quality of care, access, and effectiveness.

Outcomes research is applied to clinical and population based research that seeks to study and optimize the end results of healthcare in terms of benefits to the patient and society. The intent of this research is to identify shortfalls in practice and to develop strategies to improve care.

Like clinical trials, outcomes research seeks to provide evidence about which interventions work best for which types of patients and under what circumstances. However, the evaluation methodology of outcomes research may include both experimental and non-experimental designs: further, the "intervention" being evaluated is not limited to medications or new clinical procedures, but may also include the provision of particular services or resources, or even the enforcing of specific policies and regulations by legislative/financial bodies. Also, while traditional clinical trials focus primarily on therapeutic efficacy and safety, outcomes research may consider additional parameters such as cost, timeliness, convenience, geographical accessibility and patient preferences. Consequently, the field is more multi-disciplinary, involving, in addition to healthcare professionals and the manufacturers of medical devices or pharmaceuticals, medical economists, sociologists, and public health researchers.

The results of outcomes research are used to inform the decisions of legislative bodies that make decisions related to healthcare, as well as of financial bodies (governments, insurers, employers) who seek to minimize cost and waste while ensuring the provision of an acceptable level of care. Patients also have a significant stake in outcomes research because it facilitates their decision-making, both in deciding what intervention is best for them given their circumstances, and as members of the public who have ultimately to pay for medical services.
