Abstract
As our population ages, so grows the amount of medical expenditures. In the future, elderly people will be better organized, more assertive and have higher expectations of their quality of life. More advanced health technologies have been developed with potential harm as well as beneficial effectiveness. We should provide the patients with health technologies with high scientific evidences. Randomized control trials (RCTs) provide the highest level of scientific evidence, but cannot always be performed because of ethical, practical or financial limitations, and do not always reflect what occurs in real clinical practice. However, patient registries can be used to evaluate patient outcomes through prospective evaluation of a structured collection of clinical information. Therefore, patient registries can complement RCTs.
