 This segregation of clinical research from clinical care has also had significant drawbacks. It makes clinical research much more expensive and much more difficult to conduct. Given that studies are conducted in specialized environments, this approach has also undermined to some extent the relevance that the findings of clinical trials have for clinical care. For example, clinical trials assessing possible new treatments for hypertension are conducted in individuals who are aware that the trials exist and take the time to find out what is required to enroll. These studies frequently have trouble enrolling sufficient numbers of participants and take years to complete. At the same time, on the other side of the clinical research/clinical care divide, millions of patients with hypertension who might be eligible for a clinical trial are obtaining care from their doctors. Moreover, the countless data points generated by these encounters, what dose did the patient receive, did they experience any side effects, how long did they last, end up gathering dust in the patients’ medical records rather than being systematically collected and used to inform future practice.
