Abstract
Background/Objectives: Our study examined 5-year patient and graft survival outcomes among non-smokers, former smokers, and active smokers at the time of liver transplantation (LT) and immediate post-operative complications and short-term outcomes following LT. Methods: This was a retrospective study that examined all liver transplants occurring at Cleveland Clinic Main Campus between January 2015–October 2022. Kaplan–Meier curves examined survival outcomes, and Cox’s multivariate regression analysis was performed. Results: Over the 5-year period, patient survival did not differ statistically between patient groups (all p-values >0.05). However, graft survival was significantly lower in active smokers (p = 0.012). In the multivariate analysis, age (HR = 1.03, 95% CI 1.01–1.05, p = 0.002) and admission to the ICU (HR 1.68, 95% CI 1.13–2.50, p = 0.01) were positively associated with overall mortality. Immediate and short-term complications did not differ statistically between patient groups. Cardiovascular disease (22.5%) was the most common cause of death among all patients. Conclusions: Though our study did not show decreased patient survival outcomes, our findings are in line with previous studies that have shown that pre-transplant smoking is associated with overall reduced graft survival. Combined with the risk for de novo malignancy and cardiovascular events post transplant, smoking cessation before LT should be encouraged to ensure graft longevity.
