Smoking cessation for hospitalized smokers: an evaluation of the "Ottawa Model".
INTRODUCTION Interventions for hospitalized smokers can increase long-term smoking cessation rates . The Ottawa Model for Smoking Cessation ( the " Ottawa Model " ) is an application of the " 5 A 's " approach to cessation , customized to the hospital setting . This study evaluated the impact of implementing the Ottawa Model in 9 hospitals in eastern Ontario . METHODS The RE- AIM ( Reach , Efficacy , Adoption , Implementation , and Maintenance ) framework was used to evaluate the intervention . Trained outreach facilitators assisted 9 hospitals to implement the Ottawa Model ; program delivery was then monitored over a 1-year period using administrative data and data from a follow-up data base . A before- and -after study was conducted to gauge the effect of the Ottawa Model program on cessation rates 6 months after hospitalization . Self-reports of smoking cessation were biochemically confirmed in a r and om sample of patients , and all cessation rates were corrected for potential misreporting . RESULTS Sixty-nine percent of the expected number of smokers received the Ottawa Model intervention . Controlling for hospital , the confirmed 6-month continuous abstinence rate was higher after , than before , introduction of the Ottawa Model ( 29.4 % vs. 18.3 % ; odds ratio = 1.71 , 95 % CI = 1.11 - 2.64 ; Z = 2.43 ; I(2 ) = 0 % ; p = .02 ) . The intervention was more likely to accomplish counseling for smokers than delivery of medications or postdischarge follow-up . Attitudinal , managerial , and environmental challenges to program implementation were identified . DISCUSSION Trained outreach facilitators successfully implemented the Ottawa Model in 9 hospitals leading to significantly higher long-term cessation rates . The public health implication s of systematic cessation programs for hospitalized smokers are profound
