They still send referrals, appointments, results, etc. by post, both within the health system and to patients. They also have no system to flag things automatically - a doctor prescribes a medication and the system doesn't automatically flag up that that medication is not suitable for a patient with a particular second condition or already on a particular medication. My wife has had to point out that medications prescribed for her and known to interact fatally with other meds that she is on. Similarly for my son who is thought to have an allergy to particular medications, but has accidentally been prescribed unsuitable ones.
The systems don't automatically schedule calling patients in for blood tests, breathing tests, heart checks or other tests that need to be carried out regularly when on certain medications. Basic clerical tasks that get missed and could be automated. My son has just been called in for a blood test that should apparently be carried out every 6 months. This is the first time, despite being on the medication for 24 months - and was only picked up because the GP practice has staff with time on their hands at the moment (due to Covid restrictions) and they have been trawling through patients' notes.
The systems are also awful for staff. A colleague of my wife (a community psychiatric nurse) was sacked, as one of his patients died and hadn't been seen for a couple of months beforehand despite being on the list for a fortnightly visit. The consultant had discharged him, which left the CPN to tidy up the "paperwork" and issue the discharge letter from the system. Because the consultant, despite repeated emails, had failed to finalise a document on the system, the CPN could not issue the discharge. So the patient, despite being discharged by the consultant, was technically still on the books and the CPN was sacked for not visiting a patient that he should not have been seeing as he should no longer have been a patient!
My wife was hassled for months for paperwork that she had not completed. Again the system would not let her do so, as someone in another department, on another site, had not finalised their documents and would not respond to repeated requests.
Any sensible system would allow people to finish their part and bounce the control and responsibility back to those that have failed to do their part, rather than bombarding those unable to do anything about it with threatening prompts and holding them responsible.
