More than half of people surveyed in an exclusive poll for ITV News oppose the doctors' strike over pensions that will take place on Thursday.
In the ITV News Index survey carried out by ComRes showed that 51% were against the industrial action, while 32% supported it.
17% of the 2,059 people questioned did not express an opinion.
Science and Medical Editor Lawrence McGinty has the full report:
The health service "looks like a supertanker heading for an iceberg", the head of the NHS Confederation warned, after another survey reveals that almost half of its leaders think cost cutting will reduce quality of care for patients over the next year.
Research, carried out before the confederation's annual conference in Manchester, shows that NHS leaders fear that growing financial pressures will damage patients' quality of care.
Of the 252 chief executives and chairs of NHS organisations questioned, almost half believe the financial burden on the health service is "very serious" and 47% say this means quality of care will reduce over the next 12 months.
The warning comes as staff employed by the British Medical Association prepare to go on strike today in a row over pay, a day before doctors represented by the group take industrial action in a separate dispute over pensions.
Hundreds of members of the GMB who work for the BMA will walk out for 24 hours after rejecting a pay offer of 1.5%, with an extra 0.5% for high performers.
It will be the first strike by BMA staff in the 180 years the organisation has been in existence, said the GMB, whose members include regional officers, researchers, librarians, administrative staff and industrial relations officers.
