• TITLE: Assessing the Relative Efficiency of Health Systems in Sub-Saharan Africa Using Data Envelopment Analysis

  AUTHORS: Samuel Ambapour

  KEYWORDS: Technical Efficiency, Data Envelopment Analysis, Health System

  JOURNAL NAME: American Journal of Operations Research, Vol.5 No.1, January 14, 2015

  ABSTRACT: We assess the relative efficiency of health systems of 35 countries in sub-Saharan Africa using Data Envelopment Analysis. This method allows us to evaluate the ability of each country to transform its sanitary “inputs” into health “outputs”. Our results show that, on average, the health systems of these countries have an efficiency score between 72% and 84% of their maximum level. We also note that education and density of population are factors that affect the efficiency of the health system in these countries.
