Poor Practitioner Adherence to Clinical Tobacco Use Guidelines in Liver Transplant Recipients.

UNLABELLED: Tobacco use is a modifiable risk factor for cardiovascular events (CVEs) in liver transplant recipients (LTRs), but there is a paucity of data about practitioner adherence to tobacco cessation guidelines for LTRs. We sought to assess adherence to these guidelines as a predictor of CVEs after liver transplant.

METHODS

We conducted a retrospective, observational, cohort study of adult LTRs from 2010 to 2016 at a large urban, tertiary care transplant network.

RESULTS

Of 572 LTRs (mean age' 56.9; 64.1% male), 325 (56.8%) were never, 191 (33.4%) were former, and 56 (9.8%) were current tobacco users before liver transplant. Most LTRs (59%) had their tobacco use assessed annually by transplant providers. Among current users, documented tobacco cessation interventions decreased over time' and <25% were offered pharmacologic treatment or referral to counseling. There was no difference in CVEs between tobacco users who received cessation interventions compared with those who did not.

CONCLUSIONS

This single-center study suggests that although tobacco use cessation counseling and interventions were not associated with a decrease in CVEs, evidence-based interventions for tobacco use were under utilized in this high cardiac risk population. These findings underscore missed opportunities for transplant practitioners to provide tobacco use cessation interventions to LTRs, which potentially could reduce CVEs.
