Abstract

This report describes a modelling framework for calculating the return on investment (ROI) for GSK's Partnership for Prevention preventive healthcare progamme. Subsequently, general challenges in calculating an ROI for preventive health programmes are discussed and evidence on the effectiveness of specific interventions is included in Partnership for Prevention is outlined. The report includes a case study to calculate the Partnership for Prevention's ROI in South Africa.
