Don’t get sick anywhere but at home:
…doctors in Tanzania complete less than a quarter of the essential checklist for patients with classic symptoms of malaria, a disease that kills 63,000-96,000 Tanzanians each year. The public-sector doctor in India asks one (and only one) question in the average interaction: "What’s wrong with you?". In Paraguay, the amount of time a doctor spends with a patient has nothing to do with the severity of the patient’s illness…these isolated facts represent common patterns…three years of medical school in Tanzania result in only a 1 percentage point increase in the probability of a correct diagnosis…One concern with measuring doctor effort through direct observation is that the doctor may work harder in the presence of the research team.
