I’ve been struck recently by how little we (or at least I) seem to know about variations in use of health services across the world, and what drives them. Do people in, say, India or Mali use doctors “a lot” or “a little”. Even harder: do they “overuse” or “underuse” doctors? At least we could say whether doctor utilization rates in these countries are low or high compared to the rate for the developing world as a whole. But typically we don’t actually make such comparisons – we don’t have the numbers at our fingertips. Or at least I don’t.
I’m also struck by how strongly people feel about the factors that shape people’s use of services and what the consequences are. There are some who argue that the health problems in the developing world stem from people not getting care, and that people don’t get care because of shortages of doctors and infrastructure. There are others who argue that doctors are in fact quite plentiful – in principle; the problem is that in practice doctors are often absent from their clinic and people don’t get care at the right moment. There are others who argue that doctors are plentiful even in practice and people do get care; the problem is that the quality of the care is shockingly bad. Who’s right?
