El sistema GRADE: un cambio en la forma de evaluar la calidad de la evidencia y la fuerza de recomendaciones

Ignacio Neumann; Tomas Pantoja; Blanca Peñaloza; Lorena Cifuentes; Gabriel Rada

Individual clinicians and organizations making health care decisions should not only consider the magnitude of the benefits and harms of different courses of action (interventions), but also the confidence we can have in those estimates. The Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) approach offers a systematic and transparent way to summarize the evidence, to rate the confidence we can have in the effects of the interventions and to move from evidence to recommendations. The GRADE approach has been adopted by several organizations worldwide, including the World Health Organization and the Cochrane Collaboration. In Chile, this approach has already been used by guidelines produced by the Chilean Ministry of Health. In this paper we describe the core concepts of the GRADE approach to rate the quality of the evidence and to grade the strength of recommendations. As clinicians, being familiar with such concepts may be helpful to make decisions informed by the best available evidence.

OBJETIVO: Presentar una metodologia para la evaluacion de la relacion costo-efectividad en centros de atencion primaria de salud (APS) a partir del modelo de atencion familiar promovido en Chile y evaluar los resultados de los dos primeros anos de funcionamiento del primer centro piloto que funciona bajo este nuevo modelo de atencion primaria. METODOS. Se realizo un estudio de costo-efectividad, con una perspectiva social y un horizonte temporal de un ano. Para comparar el centro intervenido (universitario) con el centro de control (municipal) se construyo el indice compuesto de calidad de los centros de salud familiar (ICCESFAM), que combina indicadores tecnicos y la percepcion de los usuarios de los centros en seis dimensiones: accesibilidad, continuidad de la atencion medica, enfoque clinico preventivo y promocional, resolutividad, participacion, y enfoque biopsicosocial y familiar. Para calcular los costos se tomo en cuenta el gasto en los centros, el ahorro producido al resto del sistema sanitario y el gasto de bolsillo de los pacientes. Se estimo la razon costo-efectividad incremental (RCEI) y se realizo un analisis de sensibilidad. RESULTADOS: El centro de salud universitario resulto 13,4% mas caro (US
