For the point of arguing with strangers, yes, I agree that neither PubMed nor any other entities will provide you with what you need. I don't think that it is possible to acquire an understanding of an issue without some domain knowledge, at least on how to get the data.
But to gain a deeper understanding of the flaws of any country's health (or any) system, there is no way around that except by comparing it with data from other countries. And that might be hard, which is why professionals spend a lot of time on it.
