Calculating and investigating the trend of Inequality in the Distribution of Pharmacies across Iran using Gini coefficient and Lorenz Curve: a population based study

Abstract

Abstract Background Health systems always face financial resource constraints to achieve their goals, but on the other hand, the equitable distribution of these resources throughout the system is of paramount importance. Therefore, this study was conducted to examine equality in the distribution of pharmacies in all Iranian provinces. Methods This study is a retrospective examination of the trend of equality in the distribution of pharmacies throughout Iran over three five-year periods, using the Gini coefficient and Lorenz curve. Results The results of this study indicate that the Gini coefficient for the distribution of pharmacies in Iran has been decreasing over the past decade, indicating an improvement in equity in this area. Although the current level of the Gini coefficient is still not acceptable, it is showing a trend towards upgrading. Conclusion The Iranian Ministry of Health has implemented effective policies that have improved the distribution of pharmacies in Iranian provinces over the past decade. This improvement can serve as an example for other developing countries facing similar challenges in the distribution of health resources.
