Sarah Girdwood is a health economist who has worked for the Health Economics and Epidemiology Research Office (HE2RO) in Johannesburg since October 2016. She holds a Masters in Economics from the University of Oxford. Her health economics research experience and interests include cost-outcome and cost-effectiveness analysis, economic evaluation and decision analytic modelling, and geospatial modelling for efficient resource allocation. She has worked on a number of projects, including: the cost and outcomes of HIV and TB prevention and treatment; geospatial logistics optimisation analysis for the scale-up of viral load monitoring in countries under the EQUIP grant; a CDC-funded study to optimise specimen transportation in South Africa; as well as studies looking at the health economics of new technology such as point of care and plasma separation cards for scaling-up viral load coverage in resource limited settings.
The Healthcare Cost and Outcomes Model (HCOM) provides a simple tool for analysts and decision-makers to determine the cost-effectiveness of a healthcare intervention in which resources are consumed to produce certain healthcare outcomes.
