In August 2021, NHS Scotland’s A&E department’s saw 77.8% within 4 hours.
In the same period, NHS England saw, on average, only 66.2% and NHS Wales saw only 60.1%.
NHS Scotland is thus 17.5% faster (11.6% of 66.2) than England and 26.5% faster than Wales.
The real gap with England is probably even greater as NHS England cheats. NHS England starts the clock again after patients are admitted while NHS Scotland counts from arrival in A&E.
