Objective: The objectives of this work were to examine changes over time in degree of staff support for the implementation of a smoke-free policy in Canada's largest public mental health and addiction teaching hospital and to assess the impact of the policy on patient behavior.
Method: Staff completed an anonymous survey, which assessed views toward the smoke-free policy and perceived change in patient behavior, 2-7 and 31-33 months after an indoor smoke-free policy was implemented (September 21, 2005). Objective indicators of patient behavior were also collected in the form of number of emergency code whites (aggressive behavior) and that of code reds (fire) called 1 year prior to and 2 years following policy implementation.
Results: Survey response rates were 19.0% (n=481) and 18.1% (n=500) at 2-7 and 31-33 months, respectively. The proportion of staff who supported the policy increased from pre-implementation (82.6%) to post-implementation (89.1%), and a high level of support was maintained 2 years after policy enactment (90.1%). The number of emergency codes did not significantly change after policy implementation, and staff did not perceive a change in most forms of patient behavior.
Conclusion: A smoke-free policy can be implemented in a large psychiatric hospital with a high degree of support from staff and no substantial negative impact on patient behavior.
