Abstract:

Objectives: The principal objective of the study was to conduct a descriptive review of 1.000 clinical trials (CT) evaluated by the Research Ethics Committee (REC) of a universitary hospital the Autonomous Region of Madrid, to define the map of current clinical research and its concordance with official priority lines of investigation in Spain.

Methods: This is a prospective and analytic observational study of 1.000 CT, (980 with medicines), whose data were collected during a period of six years (May 1999-May 2005) in the Hospital Universitario La Paz of Madrid. It analyzes the intrinsic characteristics of the 1.000 CT evaluated over this period.

Results: For this study, 621 CT are being conducted in the medical area, 99 in pharmacology, 90 in surgery, 87 in pediatrics, 42 in primary care centers, 28 in anesthesia and resuscitation, 25 in obstetrics and gynecology, 13 in central services, and 13 in external centers that are non-dependent on the public health system. Of them, 151 CT are uni-center and 849 multi-center, 490 of which are international. In terms of development phase, 103 are phase I, 128 phase II 468 phase III, and 215 phase IV. Sixty-six observational studies were evaluated, as well as 20 epidemiological studies. In 86%, the sponsor is the pharmaceutical industry. In 597 of the CT, the principal objectives of the study have been to evaluate efficacy and safety. The population in 913 of the CT is adult, and pediatric in the remaining 87.

Conclusions: The CT with medicines were the most often evaluated, and the most frequent of those being phase III protocols, multi-centric and international, with primary objectives of efficacy and safety in adult patients, and sponsored almost exclusively by the pharmaceutical industry. The medical attending area of the hospital has the greatest prominence of studies and the priority research lines were infectious diseases, especially HIV infection, prevention of cardiovascular risk, rheumatological pathology, and studies of bioavailability. Genetic studies (pharmacogenetics and investigation of genes responsible for pathologies) have in recent years become an important component of CT.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."


Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."


Hubert Wolterbeek

"There are many scientists who can not afford the rather expensive subscriptions to scientific journals. Open access journals offer a good alternative for free access to good quality scientific information."


Fidel Toldrá
(Instituto de Agroquimica y Tecnologia de Alimentos, Spain)

"Open access journals have become a fundamental tool for students, researchers, patients and the general public. Many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis. The articles are among the best and cover most scientific areas."
