Under-pressure ambulance chiefs in Cornwall say they are handling an extra 470 incidents per day compared to five years ago – and they expect to deal with more than 10,000 calls over the bank holiday weekend.

They are urging people: ’If you need medical help but it is not an emergency consider other alternatives and help keep 999 and hospital emergency departments (EDs) free for those most in need.

’A large proportion of the calls we receive are not for time-critical, life-threatening emergency situations and so we are encouraging people to think twice before they call.

’Alternative health care options include visiting your nearest minor injuries unit or choosing over-the-counter remedies available in most high street stores and supermarkets.

’GP out-of-hours services are also available.

’If you are going out for the day please remember to take any regular medications with you and check the weather forecast to ensure you are well prepared for any eventuality.’

NHS 111 is available 24 hours a day, 365 days a year..

Ken Wenman, the chief executive of SWASFT, said: ’We know from past experience that the summer season and the influx of visitors can put extra strain on our services, as many people who are visiting the region, and would normally visit their GP, will often dial 999 or visit the nearest emergency department instead.

’We would advise people who need help to think about the alternatives and instead of visiting an emergency department or dialling 999, go online to see which other health services are available locally. With more than five million visitors to the region every year it is very important that you choose well.’
