Unadjusted associations in observational studies should not guide decisions ("hospitals have a lot of sick people, therefore I should stay away from hospitals because they will make me sick!"). Either use a randomized trial, which is the gold standard for establishing causal association, or use an observational study and adjust for confounding and other biases appropriately.
I do avoid hospitals (except in emergencies) and precisely because they are dangerous.

Personal observation says that LWers tend not to drink very much or often. Perhaps that should change, to the degree suggested by the article?
