I miss NHS fax machines
As a trainee doctor, ward fax machines were perfect "push notifications". During a busy day we sent off blood tests, arranged investigations. While working on a busy ward it was brilliant that as soon as a result was available or a test reported, the fax machine buzzed. At next opportunity we would check the result, initial it, and stick it in the notes.
The current expensive network systems are miles away from providing the speed and convenience of this setup. We have no push system, and are reduced to repeatedly logging in and going through interface-hell to see if an important result is available yet.
Providing timely clinical information to busy medical staff in the NHS has without a doubt gone a long long way backwards since the 1990s :(
