Smoking wardens will be operating at Doncaster and Bassetlaw Hospitals in a bid to stub out the habit on hospital grounds.
Smokers will be asked to move out of hospital grounds to smoke their cigarettes.
Despite not accepting smoking at Doncaster Royal Infirmary for years, it was previously up to staff to ask people not to smoke.
Occasionally, such staff received abuse from smokers, many standing next to no-smoking signs while they smoked.
Now with the establishing of the smoking wardens, it is hoped fewer people will smoke on hospital grounds and that incidents of abuse towards staff will be reduced.
Heather Keane, assistant director of nursing for patient experience and quality at the Trust, said: “This is not about preaching anti-smoking messages to people, but about people realising that the Trust hospitals are smoke-free environments.
“Our staff and the public have been consulted on this and the vast majority gave it their support, so we are keen to improve the hospital environment for everybody.
“Many people can be seen smoking outside our sites, often close to entrances or under open windows.
“Cigarette smoke is obviously not something we want floating onto our wards or being breathed by our patients, so we are taking these steps to reinforce the fact smoking is not allowed on our grounds. If people want to smoke, we will be asking them to do so from the nearby public footpaths.”
