A special ambulance will be stationed at popular holiday parks this summer to ease pressure on local health services.
The treatment centre will be based at Butlins and Fantasy Island in Ingoldmells during the peak tourist season.
It follows a successful trial last year by East Midlands Ambulance Service.
The move is designed to reduce pressure on local health services during the summer when the population in the Skegness area significantly increases with visitors.
The purpose built ambulance provides a mobile treatment centre with seating for the patient in the centre of the vehicle. It allows medical staff to work in an environment similar to an A&E cubicle.
The vehicle, which will also spend time at the Golden Sands Resort in Mablethorpe, is expected to be in place during Easter, May Bank Holidays and from June to September.
It will be manned by an emergency care practitioner able to treat medical conditions and injury.
Butlins resort director Chris Baron said: “The ambulance gives reassurance for people to know it there, particularly as some visitors have existing health conditions they may be worried about.”
A spokesman for EMAS said: “This approach was successful in 2014 with many holidaymakers being treated in the facility meaning they avoided an unnecessary trip to A&E.
“We’re pleased to be operating the scheme again in 2015 and confident that it’ll again prove to be beneficial for those who need treatment for a medical condition or injury.”
The treatment unit will operate all week, at Fantasy Island from noon to 3pm and Butlins from 3pm to 6pm.
