Abstract
This descriptive study identifies trends in clinical trial registration in the World Health Organization International Clinical Trial Registry Platform (ICTRP) for Latin America and the Caribbean (LAC), from 2007–2013, and provides adjusted estimates for registration rates by population and publications (2007–2011). Trends and data are presented by subregion and language in interactive graphs, including annual registration rates by population (2007–2011) and publications (LILACS and MEDLINE) listed in SCIENTI Network (Science and Technology Indicators). Of the 11 945 clinical trials involving LAC countries, 8 282 were in South America, with Brazil leading at 4 070 (49%); 2 421 in North and Central America, with Mexico leading at 1 886 (78%); and 1 242 in the Caribbean, with Puerto Rico leading at 857 (69%). After adjusting by population and publication rates Chile, Panama, Argentina, and Peru led registration rates per 1 million inhabitants. Variations in the number of trials per year are quite substantial. Clinical trial registration increased in a steady yet inconsistent way. The implementation of the Policy on Research for Health has been followed by an increase in countries that require registration and have established clinical trial registries. However, there is room for improvement in adherence throughout LAC. Trial registration is offered gratis by Brazilian, Cuban, Peruvian, and United States registries, among others.
 
Estudo descritivo que identifica as tendências no registro de ensaios clínicos na Plataforma Internacional de Registro de Ensaios Clínicos (ICTRP) da Organização Mundial da Saúde (OMS) para América Latina e Caribe de 2007 a 2013, e apresenta estimativas ajustadas dos índices de registro por população e publicação (2007–2011). As tendências e os dados são apresentados por sub-região e idioma em gráficos interativos, incluindo os índices anuais de registro por população (2007–2011) e publicação (LILACS e MEDLINE) listada na SCIENTI Network (Science and Technology Indicators). Dos 11.945 ensaios clínicos realizados nos países da América Latina e Caribe, 8.282 foram conduzidos na América do Sul, na sua maioria (4.070) no Brasil (49%), 2.421 nas Américas Central e do Norte, na maior parte (1.886) no México (78%), e 1.242 no Caribe, em maior número (857) em Porto Rico (69%). Após o ajuste por população e publicação, Chile, Panamá, Argentina e Peru apresentaram os maiores índices de registro por 1 milhão de habitantes. A variação no número anual de estudos é bastante considerável. Verificou-se um crescimento estável, porém inconsistente, no registro de ensaios clínicos. Com a implementação da Política para pesquisa em saúde, aumentou o número de países em que o registro de ensaios clínicos é exigido e que implantaram registros próprios. No entanto, é possível melhorar ainda mais a adesão na América Latina e Caribe visto que este registro é gratuito no Brasil, Cuba, Peru e nos Estados Unidos, entre outros.
