Bolton LMC surveyed the town's 169 GPs and, of the 98 respondents, 67 said they wanted to see the project axed, 20 said they were keen to see it progress and the others were undecided.
Currently just eight of the town's 57 practices have uploaded records to the system, with a further three set to join them.
Although Bolton PCT and Connecting for Health claim more are set to follow, Dr Chris Woods, LMC member, said they faced 'an uphill task' in convincing many of the town's GPs.
'There are concerns about consent and confidentiality which have not been addressed. I find if difficult to see how it can progress significantly in Bolton while so many GPs have those concerns,' he said.
A Bolton PCT spokeswoman said: 'Once the summary care record is operational within urgent care services in Bolton we'll be able to demonstrate the benefits it brings in terms of safe and efficient care. We hope that once GPs see it in use they will want to access these benefits.'
Thirty-four of Bolton's 57 practices are signed up to the scheme, according to Connecting for Health.
