Post-discharge tobacco abstinence in a Mumbai hospital after implementation of tobacco cessation counseling: A pragmatic evaluation of the LifeFirst program

BACKGROUND: Hospitalization provides a key opportunity to address tobacco use. Few studies have examined cessation treatment in hospitals in low- and middle-income countries (LMIC). We aimed to measure tobacco abstinence among individuals discharged from a Mumbai hospital after the implementation of cessation counseling compared to abstinence among those discharged pre-implementation. METHODS: Pre-post intervention study in the Prince Aly Khan Hospital, Mumbai pre- (11/2015-10/2016) and post-implementation (02/2018-02/2020) of LifeFirst counseling. LifeFirst is multi-session (up to six sessions) counseling extending from hospitalization up to six months post-discharge. Primary analyses compare self-reported 6-month continuous abstinence among hospitalized individuals post-implementation (intervention) with pre-implementation (comparator) using an intent-to-treat approach that includes all participants offered LifeFirst post-implementation in the intervention group. Secondary analyses compare those who received ≥ 1 LifeFirst session with the pre-implementation group. RESULTS: We enrolled n = 437 individuals pre-implementation (8.7% dual use, 57.7% smokeless tobacco, 33.6% smoking) and n = 561 post-implementation (8.6% dual use, 64.3% smokeless tobacco, 27.1% smoking). Post-implementation, 490 patients (87.3%) accepted ≥ 1 counseling session. Continuous abstinence 6-months post-discharge was higher post-implementation (post: 41.6% vs. pre: 20.0%; adjusted odds ratio [aOR]: 2.86, 95% confidence interval [CI] 1.94-4.21). Those who received LifeFirst had higher odds of continuous abstinence compared to pre-implementation (aOR: 2.95, 95% CI 1.98-4.40). CONCLUSION: Post-discharge abstinence was more common after implementation of a multi-session tobacco counseling program for hospitalized patients compared to abstinence among patients hospitalized before implementation. These findings represent observational evidence of a promising association between post-discharge abstinence and a hospital-based tobacco cessation program implemented within routine practice in an LMIC setting.
