The primary aim of this study is to examine the efficacy of a 12-week nurse-delivered relapse management intervention designed with conceptual underpinnings from Self-efficacy Theory to enhance smoking abstinence of hospitalized smokers following their hospital discharge. Specifically this study asks, does a 12-week Self-efficacy Theory driven relapse management intervention enhance smoking abstinence following hospitalization by increasing smoking abstinence point prevalence as measured by carbon monoxide validated self-reports of smoking, when compared to subjects receiving only enhanced usual care?
