If you read a bit about the Joint Commission Process, you will see that health care outcomes in hospitals are declining, despite increasingly stringent, taxing requirements and processes, this mainly (IMO) has to do with overworked, overstressed staff making increasingly unfortunate errors. They are focusing on the wrong thing. Nurses need less patients, there need to be more staff doctors, there are many things that need to happen prior to making the OUTDOORS of a hospital non-smoking if it's far enough away from entry/exit.
I'm not going to argue that smoking isn't gross, but if you use standard precautions all the time as should be done, smoking will not make a difference (except to make employees struggling to quit because they need the job more stressed out). The Washington Post did a story on the JO a while ago, and it's been fairly well documented, since then.
I have been through the Joint Commission process several times (including at least two hospitals) it was a joke. But sure, risk actuary tables and demonizing tobacco and whatnot can fix that. Surely.
It's not that I don't see the logic Bad Ninja, and if hospitals want to hire non-smoking staff, they are free to do so. But I am in major doubt that health outcomes will drastically change....
