Researcher: Every year approximately the same number of people die of iatrogenic "disease"—that is, as a direct result of medical treatments or hospitalization—as die of all other causes combined.
Evidence
Every year approximately the same number of people die of iatrogenic “disease”—that is, as a direct result of medical treatments or hospitalization—as die of all other causes combined.
Conclusion
Therefore, if all medicine could find ways of preventing all iatrogenic disease, the number of deaths per year would decrease by half.
Evaluate
The argument assumes that 100 percent of the people who did not die of iatrogenic disease would survive for the remainder of the year or longer. If someone were to die that same year, then the number of deaths per year would be reduced by less than half. Also, keep in mind that iatrogenic disease is the result of medical treatments or hospitalization.
Such people are bound to include at least a few who die as a result of the complication for which they were seeking medical care.
