@ Sqad. Cannot remember specifically all of the details now, but I am pretty sure in the original proposals, It was not suggested that polyclinics were geographically located at hospitals, nor that polyclinics would replace all the GP surgeries.
In London, the original proposal was for 150 polyclinics across the capital, most being generated out of an expansion of existing GP surgeries. In addition ,there was talk of adding GP units to Hospitals, to direct some of the flow away from acute admissions.
Sounds like a plan, to me....
One thing is for sure - the status quo - that the current system of tiers is no longer adequate. Primary care needs major revision, Specialist care in the hospitals requires regionalisation for true excellence.
