Health bosses in Lincolnshire say patients are missing out on GP appointments because they are not aware that they can book in the evening or at the weekend.
GPs say most of the appointments aren't being filled and many people are making unncessary trips to Accident and Emergency.
A new scheme is underway in Louth whereby patients can see their doctor in the evening or at the weekend. Dr Leke Oyedotun is one of the regular doctors on duty.
He says: "The appointments are a little bit longer. Most GP appointments are for 10 minutes, this is for 15 minutes so it does take in to account that we don't know the patients. But in our GP practices, we don't know all our patients, we get to meet them over time.
"It is a bit tricky but most doctors are well equipped in dealing with uncertainty and new patients."
