What health system was used before the NHS was introduced. I was born before that time and in hospital but forgot to ask my, now dead, mother. someone said doctor's vouchers (where one paid in advance) but what about the poor people who couldn't afford a doctor. My mother gave birth to 6 children and always in a Maternity home, or hospital, and we weren't particularly rich. There weren't workhouses then.
I and my younger sister were delivered by nuns, we found our 'receipts' when dad passed away and I couldnt believe everything was chargeable - bed, food, delivery etc all listed separately and we werent posh, wee bro was delivered in a hospital for 'free' we keep telling him how he was the 'cheap' one lol
By the 1930's subsidised hospital care was available in the 'public wards' of different hospitals - themselves often private companies or charities. At the same time, the existing workhouse system was modified to provide hospital care which is why so many hospitals even now are former workhouses. This made the introduction of the NHS easier than might otherwise have been the case, as the outline of subsidised hospital beds had already been laid. So you might have been born in one of these wards.
I remember reading an account in a book (I think it was called "Voices and Images of the Great War", I'd reccomend it) it told a story of a woman giving birth at home whose husband was away fighting the Germans, there were complications and a doctor was called he refused to attend to the birth until he'd been paid, the family were poor so everyone in the street clubbed together to pay him whilst he stood outside the front door waiting.
It was common in my part of the world to pay the doctor so much a week, in the 1930's my grandfather paid the local doctor one shilling a week and built up credit to draw on when his services were needed. Apparently this was a regular practice, obviously beneficial and convenient to all concerned. Whether this was a scheme local to the area I couldn't say.
It was also common for tenants to pay their landlord a little extra on top of the rent every week to cover arrears during shutdowns, strikes etc. if spare money was available.
