Differences Between Essential Medicines Lists in 135 Countries and the World Health Organization's Model List of Essential Medicines

The World Health Organization (WHO) has developed a model list of more than 400 medicines and recommends that each country adapt the list to its own circumstances. More than 100 countries have developed essential medicines lists.

Some countries have essential medicines lists that are very similar to the WHO's model list and other countries have lists that are very different from the WHO's model list. Differences between the WHO list and country lists could be explained by features of the country including population demographics, disease prevalence, Gross Domestic Product (GDP), and healthcare system organization. Other factors such as the influence of particular individuals or organizations may also explain differences between countries.

The purpose of this project is to compare the essential medicines lists developed by countries with the WHO's model list and to identify attributes of countries that are associated with differences from the WHO list. Predictors such as region, population, life expectancy, infant mortality rate, GDP per capita, health expenditure per capita, inequality, and the corruption perception index will be considered.
