Another Issue The Proponents Of The myHR Need To Face. Lack Of Data Accuracy.
This appeared last week:

GPs are repeatedly told that electronic medical records will fix the problems of faulty memories, illegible hospital handover notes and patients who aren’t faithful to one GP (but don’t tell you). But do you trust what your computer says?
Researchers from Perth read the electronic patient records of almost 1000 patients and then checked with the real-life patient if they were accurate.
The results focused on whether patients had received their flu vaccination or not. These searches found that, in 84% of cases, the electronic records and the patients’ memories were the same. However, in 16% of cases, the computer said no but the patient said yes — or the other way around.
The first scenario was more common by a fair stretch (the patient said they had been vaccinated, but it wasn’t on their electronic patient record).
As the researchers from the WA Department of Health pointed out, this might be because they had the vaccination at work or a pharmacy, so it was easily missed.
They also looked at the accuracy of electronic records covering the presence of diabetes, asthma, chronic heart disease or pregnancy.
They found that concordance was highest for diabetes (96%), then heart disease (92%), pregnancy (90%) and asthma (89%).
What this article is telling you is that the source articles for the myHR have very significant omissions and errors – so just how useful is it to try and use such inaccurate records in an aggregate sense. Not very would be my feeling.
More useful would be to design a program to improve the accuracy of the records we have. I suspect that would be more useful than gathering all these erroneous records together and trying to make something of them!
BTW – does anyone have the source paper – some my like to read it I suspect and I can’t find it.
