Surgery-
Can mean a doctor’s surgery, as in the building in which you practice, or even the room within the building in which you see patients.
Can mean the specialty in which one cuts people up.
Can mean the period of time one sees patients- a “morning surgery” may run from 9am-11am, an “afternoon surgery” would be 3pm-5pm.
Context is all.
The reason you have open surgeries (umm, “un-booked consultation windows” does that sound American?) in the am is because walk-ins generally tend to be sick people, who should really be seen and sorted out as soon in the working day as possible.
If you can book an appointment in advance you are more likely to be coming to discuss a chronic issue (contraception, infertility, depression, high blood pressure) and the expectation is that you won’t need to be packed off to hospital or need to start a course of treatment immediately.
The practice I am going to has 5000ish patients and 8 doctors. In two hours 8 doctors could see somewhere around 100 patients or about 2% of the practice population, given that the majority of open slots will be the “quick and easy” type, rather than the “long and complex”.
The chances of 100 patients actually turning up on any given day…not high. Also, the booked appointments start at 3pm, so you’d have to be running REALLY late for the open surgery to delay your appointments.
The NHS gives access targets to GPs here. One has to be able to see a GP within 48hrs (not necessarily your own named Dr, but a doctor within that practice), also one has to be available to see patients between 9am and 5pm- locking the doors isn’t an option, nor is refusing to see walk-ins.
Open surgeries aim to confine the crazy to the morning, and allow you
time to catch up before the booked appointments arrive. If you had opens in the evening you’d have sick people lying in bed all day who should be on treatment or in hospital, then turning up at 5pm and you having to arrange hospital admission or an ambulance outside of normal 9-5 working hours.
There honestly is method to the madness.
