Evaluation of the OECD Countries’ Healthcare System in Terms of Sustainable Development

In this paper, the healthcare conditions of 31 countries that are the members of the organization for economic and co-operative development (oecd) are measured by considering 14 indicators that are relevant to three main pillars of sustainable development.a hybrid principle component analysis and data envelopment analysis, pca-dea, is used to estimate health efficiency. for dea, the additive model in both forms of envelopment and multiplier is used to determine efficiency scores and present benchmarks and improvement plans for inefficient countries. then, decision tree analysis is used to acquire a knowledge discovery process to determine influential situations affecting the efficiency status of a decision-making unit (dmu). according to the pca-dea additive model, among 31 oecd countries, 16 countries have become inefficient such that the usa has experienced the lowest efficiency score. among efficient countries, iceland enjoys a suitable benchmark. decision tree analysis also shows that exposure to pm2.5 is an influential factor in the health efficiency status of countries.this research gives an insight into the sustainable development and healthcare system and shows the impressive effect of environmental and social factors, such as exposure to pm2.5, water quality, insurance coverage, and aids, on the healthcare efficiency of oecd countries
