A Post-Discharge Smoking-Cessation Intervention for Hospital Patients: Helping Hand 2 Randomized Clinical Trial.

INTRODUCTION: Hospitalization provides an opportunity for smokers to quit, but tobacco-cessation interventions started in hospital must continue after discharge to be effective. This study aimed to improve the scalability of a proven effective post-discharge intervention by incorporating referral to a telephone quitline, a nationally available cessation resource. STUDY
DESIGN: A three-site RCT compared Sustained Care, a post-discharge tobacco-cessation intervention, with Standard Care among hospitalized adult smokers who wanted to quit smoking and received in-hospital tobacco-cessation counseling. SETTING/PARTICIPANTS: A total of 1,357 daily smokers admitted to three hospitals were enrolled from December 2012 to July 2014. INTERVENTION: Sustained Care started at discharge and included automated interactive voice response telephone calls and the patient's choice of cessation medication for 3 months. Each automated call advised cessation, supported medication adherence, and triaged smokers seeking additional counseling or medication support directly to a telephone quitline. Standard Care provided only medication and counseling recommendations at discharge. MAIN OUTCOME MEASURES: Biochemically confirmed past 7-day tobacco abstinence 6 months after discharge (primary outcome) and self-reported tobacco abstinence and tobacco-cessation treatment use at 1, 3, and 6 months and overall (0-6 months). Analyses were done in 2015-2016.
RESULTS: Smokers offered Sustained Care (n=680), versus those offered Standard Care (n=677), did not have greater biochemically confirmed abstinence at 6 months (17% vs 16%, p=0.58). However, the Sustained Care group reported more tobacco-cessation counseling and medication use at each follow-up and higher rates of self-reported past 7-day tobacco abstinence at 1 month (43% vs 32%, p<0.0001) and 3 months (37% vs 30%, p=0.008). At 6 months, the difference narrowed (31% vs 27%, p=0.09). Overall, the intervention increased self-reported 7-day abstinence over the 6-month follow-up (relative risk, 1.25; 95% CI=1.10, 1.40; p=0.0006).
CONCLUSIONS: A 3-month post-discharge smoking-cessation intervention for hospitalized smokers who wanted to quit did not increase confirmed tobacco abstinence at 6 months but did increase self-reported abstinence during the treatment period (3 months). Real-time linkage of interactive voice response calls to a quitline, done in this trial to increase scalability of a previously proven cessation intervention, demonstrated short-term promise but did not sustain long-term intervention effectiveness.
