In these COVID times, the comparison beteen different countries health-systems is a trending topic.
The comparison is not easy as there is no easy KPI to measure.
For instance, the graph below compares number of doctors and nurses per habitant, but what good is a lot of doctors if they don't have the right infrastructure?
Possibly, life expectancy might be one of the best ways to measure the quality of the health in its broadest sense (also the prevention of deaths due to accidents etc..).
Hopefully there also is some kind of correlation between life quality and life expectancy.
Spenditure on health system as part of GDP might also be an indicator of the importance the society gives to the healt system... but, in that number you cannot see if the money is spent efficiently.
Anyway, having said this, that there is no single KPI to use to measure the quality of different health systems, there are amany KPI's that each one tells a part of the complete picture.
In this case, as mentioned, I have found the number of doctors and nurses per capita in different countries.
