The number of patients registered at under-pressure GP surgeries has soared by almost 50,000 in just two years in the West Midlands.
Figures released by the Health and Social Care Information Centre show that south and central Birmingham surgeries have seen patients numbers grow by 8,300 people- and increase of 3.4 per cent.
Sandwell and West Birmingham has seen a 3.2 per cent increase from April 2013 to 2015, meaning there are 17,181 extra patients registered with a GP.
The news will concern some patients who often have to wait days or even weeks to get an appointment with their local doctor.
In December 2013 a CQC report revealed that some visitors to a Kingsbury surgery resorted to bringing their own stools to queue outside a clinic in a desperate bid to get an appointment.
Now, figures reveal getting an appointment could be even more competitive as 968,705 more patients are registered with a GP across England as a whole.
The biggest percentage increases of all were concentrated in London.
In Westminster the number of registered patients has risen by as much as 9.0 per cent.
By contrast Dudley has actually seen a fall in registered patients - down 150 people from the 314,863 there were two years ago.
Overall, though, the number of registered patients in the West Midlands rose from 2,611,791 to 2,658,904 - an increase of 47,113.
But the Birmingham South Central Clinical Commissioning Group (CCG), which runs GP services in the city explained that the increases could be explained largely by the restructuring issues.
A spokesman said: “There are a number of factors involved in the increase in patient numbers – the main one being the increase in number of GP practices in the area we cover.
“When the CCG was established in April 2013, we had 46 General Practices with a total list size of 242,000.
“In 2014, eight General Practices joined our CCG, taking our total patient list to around 287,000.
Birmingham’s population is also generally rising by about one per cent each year and parts of our area have a relatively high birth rate and a young population, with 27 per cent of people aged under 18.
“The health and well-being of our patients remains our top priority and our practices continue to provide a good service. The CCG will also soon launch a pilot programme that will allow 125,000 of our patients to access GP services from 8am to 8pm seven days a week.”
