Abstract

Objectives: To describe the ethical and methodological quality of non-interventional post-authorization studies promoted by Hospital Pharmacy Departments (HPD).

Methods: HPD promoted studies in the 2009-2011 period included in the Spanish Agency of Medicines and Medical Devices (AEMPS) registry and/or published in "Farmacia Hospitalaria" were identified. The most relevant ethical and methodological characteristics were analyzed. Studies promoted by HPD were also compared with studies not promoted by HPD.

Results: Twenty two studies promoted by HPD, and registered in the AEMPS were identified. Within the registered studies HPD promoted studies had lower sample size estimation (41,5% vs 80%) and international scope (0% vs 24%) compared to non HPD promoted studies with significant differences (p < 0,05). None of the published studies in the journal Farmacia Hospitalaria have been registered in the AEMPS and had lower methodological quality than the registered studies promoted by HPD in characteristics such as presence of control group (3,8% vs 27,3%) (p = 0,0072) and the sample size estimation of (19,2% vs 42,8%) (p < 0,05).

Conclusion: The management and the methodological and ethical characteristics of the studies promoted by HPD should be improved according to the regulation. The registration in the AEMPS might have a positive impact on the quality of these research protocols.

Objetivos: Describir la calidad &eacute;tica y metodol&oacute;gica de los estudios posautorizaci&oacute;n de tipo observacional con medicamentos de uso humano promovidos por los Servicios de Farmacia Hospitalaria (SFH). M&eacute;todos: Se identificaron los estudios promovidos por los SFH registrados en la Agencia Espa&ntilde;ola de Medicamentos y Productos Sanitarios (AEMPS) durante 2009-2011 y/o publicados en la revista Farmacia Hospitalaria en el mismo per&iacute;odo. Se analizaron los aspectos &eacute;ticos y metodol&oacute;gicos m&aacute;s relevantes. Con el fin de conocer las diferencias de los estudios promovidos por los SFH respecto a estudios realizados por otros promotores, se compararon con los estudios registrados durante 2003-2007. Resultados: Se registraron en la AEMPS 22 estudios promovidos por SFH, que comparados con aquellos realizados por promotores diferentes, mostraron un menor cumplimiento de los aspectos &eacute;ticos recogidos en la normativa, as&iacute; como resultados m&aacute;s discretos y estad&iacute;sticamente significativos (p < 0,05), respecto a justificaci&oacute;n del tama&ntilde;o muestral (41,5% vs 80%) o &aacute;mbito internacional (0% vs 24%). Respecto a los estudios publicados en la revista Farmacia Hospitalaria (n = 52), ninguno fue registrado en la AEMPS. En comparaci&oacute;n con los estudios registrados promovidos por SFH, presentaron menor calidad metodol&oacute;gica, en aspectos tales como presencia de grupo control (3,8% vs 27,3%) (p = 0,0072) o justificaci&oacute;n del tama&ntilde;o muestral (19,2% vs 42,8%) (p < 0,05). Conclusi&oacute;n: Existen aspectos administrativos, metodol&oacute;gicos y &eacute;ticos de los estudios promovidos por los SFH que deben ser mejorados seg&uacute;n la normativa. El registro en la AEMPS, parece tener un efecto positivo en el rigor cient&iacute;fico y &eacute;tico de los protocolos de investigaci&oacute;n.
