Fourteen doctors’ leaders have written to George Osborne asking for further funding for social care in next week’s Budget.
In a letter to the chancellor, they said cuts in social care funding were putting real pressure on the NHS.
And they said investing in social care was “vital to the success of the NHS”.
The government said it was already giving local authorities access to up to £3.5bn of new funding for adult social care by 2019-20.
The signatories to the letter are led by Clare Marx, president of the Royal College of Surgeons of England, and include the leaders of a number of royal medical colleges and societies.
In their letter to the chancellor, they describe health and social care as “two sides of the same coin”.
The letter describes the impact of an underfunded social care system on the NHS, saying patients fit to be discharged are unable to leave hospital because social support is unavailable at home.
This increases the likelihood of infections and falls, they write.
The knock-on effect is that beds are blocked to new patients, they continue, “leading to cancelled appointments and operations”.
“This impacts on our ability to provide timely treatment and meet treatment targets, risking patient wellbeing, and is ultimately detrimental to the economy through delayed returns to work,” they wrote.
The doctors also said the plans for social care funding contained in the comprehensive spending review “will not suffice”.
In the letter, they suggest bringing forward the extra £700m from the Better Care Fund to this year rather than waiting until 2017, when the money was due to be spread over three years.
NHS chief executive Simon Stevens has previously said that the success of the Five Year Forward View is dependent on adequate funding for social care.
A spokesman for the Department of Health said it was essential that older and vulnerable people got the care they deserved.
“That’s why we have given local authorities access to up to £3.5bn to spend on social care and councils will have almost £200 billion to spend on local services over the lifetime of this parliament.”
