| Methods | Country: Spain, Madrid Setting: Hospital Design: Uncontrolled before‐and‐after study Analysis: Chi² test, t‐tests, Mann‐Whitney and multivariate logistic regression analyses |
|
| Participants | 1189 patients admitted during June and July 2005 (pre) and June and July 2006 (post). 184 current smokers identified (15.4%). 135 smokers agreed to participate in study: completed survey of smoking habits, social status and consumption of snuff. Pre‐ban n = 73, post‐ban n = 62 n = 55 smokers actively smoked in hospital during study period Aged: 18 years and older |
