I don’t know what to make of that statement. It might be true. It might not. There is a good amount of politics involved in how persons death is recorded.
You can read some about that here in this article:
…You might believe that when someone dies, it is pretty clear what they died of. Again, if you think that, please think again, and keep thinking until your brain bursts. You might further believe that that what is written on death certificates is an accurate record of cause of death… Ho ho.
When I started in medicine, if a patient was old, and developed a cough, then died, they would most likely be recorded as dying of chronic bronchitis. Thus it came to be that, chronic bronchitis was one of the most common causes of death. At least in the UK. Then, one fine day, it was decreed that you could not use Chronic bronchitis as a primary cause of death on a death certificate. And lo, no-one died of chronic bronchitis ever again. A fantastic medical achievement in curing the UK of chronic bronchitis?
Change your definitions, and codes, and you can cure the world of a disease – at the stroke of a pen.
Until 1948, not a single person died of Ischaemic Heart Disease (IHD), (IHD is what most people would call heart disease), anywhere in the world. Then, suddenly, millions were dying of IHD. IHD is a relatively broad diagnostic code, which incorporates myocardial infarction (MI).
What was the cause of this epidemic? Well, in 1948 the WHO decided that disease diagnoses ought to be standardised around the world, so that researchers would have some idea what they were actually looking at. So they created the International Classification of Disease (ICD). Which included IHD. And lo, an epidemic of IHD swept the world. Not, of course, in France, where they use their own diagnostic system – until 1968. A heart attack (MI) was called Cardiac Insufficience (I believe – I may be wrong on this exact terminology)…
