SHM Converge Scientific Abstract ePoster Gallery-Associations Between Tobacco Use and Tobacco Cessation Pharmacotherapy on Rehospitalization

Pdf Summary

This retrospective cohort study examined whether smoking status and prescribing tobacco cessation medications were associated with rehospitalization after hospital discharge. Using electronic health record data from a patient-centered medical home, the researchers analyzed 11,164 adult patients hospitalized between July 1, 2013, and December 31, 2020. A second analysis focused on 1,603 patients identified as current tobacco users.<br /><br />The main outcome was rehospitalization within 30, 90, and 365 days after the index hospitalization. For the first analysis, smoking status was categorized as never, former, or current. For the second, the exposure was whether a current smoker was prescribed tobacco cessation pharmacotherapy. The study adjusted for demographic factors, length of stay, and comorbidities using logistic regression.<br /><br />Results showed that current and former smokers had higher rehospitalization rates than never smokers. Among current smokers, those who were prescribed tobacco cessation medications had a lower likelihood of rehospitalization within 365 days after adjustment for confounders. However, only 19% of current smokers received tobacco cessation therapy.<br /><br />The authors conclude that prescribing tobacco cessation pharmacotherapy during hospitalization may help reduce rehospitalization risk, even without a comprehensive inpatient tobacco treatment program. They highlight a missed opportunity for hospitalists and inpatient providers to more consistently prescribe these medications and suggest that clinical decision support tools could improve treatment delivery.
