A friend of mine recently published a paper, after studying a group of
GPs located in the South of France. He found out that the diagnosis is
not reported in observations in more than one encounter out of two.

Another point is that many medical documents don't get external feedback
and can be of very low quality. In France, patients leave the hospital
with an hospitalization report. My mother in law was admitted in an
hospital for 3 days several months ago, and her "outpatient report"
didn't mention any of the things she had discussed with doctors... and
her weight was supposed to be 20 kg less than her actual one.

Wrong patient, copy-pasted document not properly actuated?

Since nobody dare having this kind of document corrected, it remains
forever wrong in hospital's records. Successfully using machine learning
demands a prior culture of data quality and information awareness.

Best,

Philippe
