VignetteBoth an electronic and a paper medical record was transferred from GP A to GP B for a new patient. A medical incident review noted the electronic record was incomplete, however the review of the paper record by GP B overlooked important information, resulting in the patient’s death.
What concerns would you have for electronic records?What concerns would you have for paper records?

![Page 21: Health Informatics Primer€¦ · health informatics • Communication must be accurate, reliable and timely – Prescriptions (from hospital or GP to Pharmacy) – Referrals (from](https://reader030.fdocuments.us/reader030/viewer/2022041017/5ecaf6ce31e6bc613a32fc9a/html5/thumbnails/21.jpg)
Computers are dumb…• They don’t learn• They can’t tell what you mean• They don’t get bored
![Page 22: Health Informatics Primer€¦ · health informatics • Communication must be accurate, reliable and timely – Prescriptions (from hospital or GP to Pharmacy) – Referrals (from](https://reader030.fdocuments.us/reader030/viewer/2022041017/5ecaf6ce31e6bc613a32fc9a/html5/thumbnails/22.jpg)
Data• Discrete variables• National Health Index – NHI • Name, date of birth, gender, address• Values collected – blood test results • Clinical data - blood pressure, clinical signs,
diagnosis, medicationsData itself is nothing…
Should provide useful, usable information that makes a difference to patient care
![Page 23: Health Informatics Primer€¦ · health informatics • Communication must be accurate, reliable and timely – Prescriptions (from hospital or GP to Pharmacy) – Referrals (from](https://reader030.fdocuments.us/reader030/viewer/2022041017/5ecaf6ce31e6bc613a32fc9a/html5/thumbnails/23.jpg)
Information• Data in context• 120/80 means something if you know it is
mmHg • However it still doesn’t tell you anything about
whether the patient is sick or well.• Need more data to provide context – , when
taken, other readings, age, medical history, medications
![Page 24: Health Informatics Primer€¦ · health informatics • Communication must be accurate, reliable and timely – Prescriptions (from hospital or GP to Pharmacy) – Referrals (from](https://reader030.fdocuments.us/reader030/viewer/2022041017/5ecaf6ce31e6bc613a32fc9a/html5/thumbnails/24.jpg)
Knowledge• Adds MEANING to information • 120/80 is high blood pressure in an infant• May be high relative to other readings in an adult• Relies on expertise to interpret.• Information to knowledge usually done by
humans, can see clinical diagnosis as this sort of process.

How to share safely…• Potential architectures• Single Clinical Information system
– Everybody accesses own part and gets views of other data.
• Centralised model– Requires very large investment– Issues with who “owns” data– Connectivity always needed
![Page 31: Health Informatics Primer€¦ · health informatics • Communication must be accurate, reliable and timely – Prescriptions (from hospital or GP to Pharmacy) – Referrals (from](https://reader030.fdocuments.us/reader030/viewer/2022041017/5ecaf6ce31e6bc613a32fc9a/html5/thumbnails/31.jpg)
