Research in Costa Rica involving human beings and its impact of on the health of costa ricans

Abstract

We evaluate the benefits of clinical research carried out in Costa Rica from the published results and a sample of informed consent forms of approved protocols. We found 30 studies on 28 pharmaceuticals and 23 published scientific papers. Results: Of surveyed medical conditions, 19% are directly related to the main causes of mortality and morbidity in our country does not seem to have been necessary for drug registration.  A placebo as control was ued in 27% of investigations; of all studies with results, 30% had not published results, 37% published positive results, 17% ambiguous or contradictory results and 13% ended prematurely. Out of the major authors responsible for the publications, 91% were affiliated with research centers abroad. Conclusions: We conclude that there is insufficient evidence to claim  that analyzed clinical research has provided a significant benefit to the health of Costa Ricans, represents a significant therapeutic option, or has provided a significant contribution to scientific research in Costa Rica.
