Over seven million patients are expected to benefit after 1100 GP practices announced they were to extend their hours.
Changes in England will mainly help over 75s
Over 75s will be given a named GP to co-ordinate care
The amount of work GPs have to do is so great is its "threatening" the future of family medicine, the BMA has warned.
Dr Chaand Nagpaul, chairman of the BMA's GP committee, said:
– Dr Chaand Nagpaul
It is clear general practice is facing a workload disaster that is threatening its long-term future.
We are seeing morale dip to a level that I cannot remember in my 25 years as a GP.
Six out of 10 GPs are considering early retirement and more than a third are actively planning to end their career early.
This could lead to a serious workforce crisis in general practice where we do not have enough GPs to treat patients.
The root cause of this crisis is that GP practices are facing an unprecedented combination of rising patient demand, especially from an ageing population, and declining resources.
Over half of GPs are considering stepping down and retiring before their mid-60s because of their heavy workload, the doctor's union has warned.
The British Medical Association (BMA) quizzed 420 GPs, 54% of whom said they believed their current workload was "unsustainable".
And 55% said their morale was "low" or "very low".
The union said that general practice is facing a "workload disaster".
As many as two million people have to wait up to three weeks for an appointment with a GP, a survey has found.
Half a million face a wait of up to a month to see their family doctor, while only one in three patients is able to secure a same-day appointment.
The research, carried out by the Daily Mail and over-50s group Saga, found that 20% of people cannot get a consultation within seven days.
Last week the Royal College of General Practitioners (RCGP) claimed more than 34 million people will this year fail to get an appointment with their GP when they seek one.[
More than 34 million people will this year fail to get an appointment with their GP when they seek one, the Royal College of General Practitioners (RGCP) has claimed.
The college's prediction that one in ten prospective patients will fail to secure an appointment when they wish is based on analysis of the latest GP Patient Survey, which was published in December.
The RGCP said the number of people who would fail to get an GP appointment when they want one will continue to rise as Government cuts and the effects of an ageing population take hold.
GPs now see 340 million patients per year in total but the NHS budget for general practice has been cut by £9.1 billion in real terms since 2004, the college said.
GP Dr Katharina Frey, who runs a small practice in Cumbria, appeared on ITV's Daybreak this morning to discuss her concerns over plans to phase out the Minimum Practice Income Guarantee (MPIG).
"Our actual patient numbers are quite low, but we have quite high overheads, so we don't really have the economies of scale" she told the programme.
Dr Frey warned the "viability" of the practice might be threatened by funding cuts.
"We want to be able to provide excellent care, but if more and more funding is going to disappear, this will be getting increasingly difficult."
The Government has decided to phase out a funding arrangement called the Minimum Practice Income Guarantee (MPIG) over a seven-year period, beginning in April - a move that doctors' leaders have warned could force around 100 GP practices to close.
MPIG means many smaller GP practices are guaranteed a minimum level of funding that is not dependent on the number of patients on their practice list.
NHS England has published an anonymised list of 98 'outlier' practices that could lose more than £3 per patient per year.
Some practices on the list will lose more than £100 per patient per year while others stand to lose around £20 or £30 per patient.
Around 100 GP practices could be forced to close due to cuts in national funding, leaving patients in rural areas without a GP, doctors' leaders have warned.
Changes to how practices are paid mean some could no longer be viable, despite the fact some "provide vital services to thousands of rural patients", the British Medical Association (BMA) said.
It warned that large areas of rural England could be left with no GP practice for local residents.
A GP who has taken all of his patients out of an information sharing scheme justified his decision "because none of that information can be properly anonymised".
Dr Gordon Gancz told Daybreak he had taken all of his patients out of the CARE.DATA scheme because "most people in the country...do not realise that their confidential and private information will be taken directly from GPs computers".
Prostate cancer will become the most common cancer in the UK "in the next 15-20 years".
"All the statistics say that prostate cancer is currently the most common cancer among men, it's about as common as breast cancer. Within the next 15-20 years it will be the most common cancer in this country.
"For the majority of the men who have it, they don't have any symptoms. That is the very reason why you need to go to the doctor, particularly when you get close to 50 and see if the test is right for you."
