Utilización de métodos analíticos novedosos en investigación clínica: recomendaciones de uso.
Investigación de síntesis y sobre el proceso de difusión de resultados de investigación clinicoepidemiológica.
Investigación metodológica y de campo en encuestas de satisfacción.
Soporte metodológico, técnico y de gestión de proyectos y acciones de investigación clínica y proyectos de investigación e innovación en Biomedicina (a través de la Unidad de Epidemiología Clínica y Apoyo a la Investigación y a través del CAIBER).
Actividades del Grupo

Grupo recientemente reconstituido que compatibiliza labores de apoyo metodológico a otros grupos del Instituto y del Hospital con estudios de investigación propia dirigidos a aumentar el conocimiento sobre la calidad intrínseca de las técnicas diagnósticas, métodos pronósticos e intervenciones sanitarias, sobre la influencia del contexto en su utilización y sobre la difusión de sus resultados en la transición investigación-aplicación en condiciones de práctica habitual.

Acciones formativas en aspectos como correcta utilización de técnicas estadísticas comunes, creación de bases de datos de calidad en investigación, elaboración de un protocolo de investigación, lectura crítica de la literatura científica en el marco de la Medicina Basada en la Evidencia.
