This is generally going to be less a doctor problem and more a hospital admin problem.
Hospitals try and employ the fewest doctors possible to save money, they schedule doctors so they have 5 minutes per patient, and they pack the schedules as dense as possible to maximize the number of cases a doctor is handling.
Any disruption here causes a delay. A patient showing up late, having questions, or the doctor needing to shit. It all adds up to the fail system.
There are simple fixes here like extending the doctors appointments beyond the average required time and hiring now doctors, but that costs money and doesn’t optimize profit for the shareholders.
