Chesterfield MP Toby Perkins is urging patients to contact him with their views on GP services.
Mr Perkins conducted a door-to-door survey of 8,500 people in the summer and found hundreds of people are struggling to access GP provision in Chesterfield and Staveley.
Thirty seven per cent of respondents told him that GP services are worse now than they were three years ago. Only a handful thought they had improved.
Mr Perkins said: “I was alarmed to hear so many people tell me that they were unhappy with their GP provision.
“Easy access to a doctor is vitally important, especially for the elderly and those with serious ongoing conditions.
“Now I’m asking people across the constituency to contact me with their concerns or plaudits about local GP services as we look to investigate the issue more widely.
“I’ll also be inviting GP practices to update us about steps they are taking to improve access.”
Mr Perkins added he was holding talks with health chiefs on how to improve matters.
He can be contacted via firstname.lastname@example.org, called on 01246 386286 or written to at 113 Saltergate, Chesterfield, S40 1NF.
