A new approach to large-scale effectiveness evaluation.

摘要

With parallel programmes and many agents operating in intervention and control areas, assessments of the effectiveness of large-scale programmes has become increasingly complex. Recognising this complexity, Cesar Victora and colleagues suggest a new approach. The district-based design proposed is welcome, and its value is multiplied when its use extends beyond comparative effectiveness assessment. With little progress towards the Millennium Development Goals in sub-Saharan Africa, complementary institutional capacity is necessary. Trained district multidisciplinary teams need to be put in place for diagnosis before interventions; relevant cross-sectoral interventions need to be designed; and supervision, monitoring, and information need to be shared to ensure accountability.
