The quantity and quality of many health care interventions are improved through the results of science, such as advanced through the medical model of health which focuses on the eradication of illness through diagnosis and effective treatment. Many important advances have been made through health research, including biomedical research and pharmaceutical research. They form the basis of evidence-based medicineand evidence-based practice in health care delivery.
For example, in terms of pharmaceutical research and development spending, Europe spends a little less than the United States (€22.50bn compared to €27.05bn in 2006). The United States accounts for 80% of the world's research and development spending in biotechnology.
In addition, the results of health services research can lead to greater efficiency and equitable delivery of health care interventions, as advanced through the social model of health and disability, which emphasizes the societal changes that can be made to make population healthiers. Results from health services research often form the basis of evidence-based policy in health care systems.
