Confusing and unsafe: Why this GP is fed up with his e-records system

Just when I think I am used to my e-health record system, they change it!
I am on my third iteration, and I am a little disappointed. I am again, still, finding it hard to document and retrieve the thread of my patient’s life and disease story.
I imagine many e-health records were created for episodic, rather than continued, medical care.
One thing that can make working with e-health records difficult is finding the chronology in office visits (seen for sore throat and started on an antibiotic), phone calls (starting to feel itchy, is it an allergic reaction?) and outside reports (emergency room visit for anaphylactic reaction).
