Around 30 per cent of people who visit A&E could be seen or treated by services outside of hospital.
This can include self care, a pharmacy, a GP or practice nurse, GP out of hours services, local urgent care and minor injury services and NHS 111.
Dr Suneil Kapadia, medical director for ULHT said: “We’ve seen a significant rise in demand on our A&Es at a time where we have a real shortage of staff.
“The people of Lincolnshire can help by using the alternative urgent care services available.
“To help ease pressures on A&Es, I urge everyone to think twice before they go to an A&E – if it’s not serious or life threatening, you shouldn’t be there.”
