Recipient age and mortality after liver transplantation: a population-based cohort tudy

Background The feasibility of liver transplantation (LT) in elderly recipients remains a topic of debate. Methods This cohort study evaluated the impact of recipient's age on LT outcome between January 2007 and May 2016 covered by the Korean National Health Insurance system (n = 9415). Multilevel regression models were used to determine the impact of recipient's age on in-hospital and long-term mortality after LT. Results All patients had a first LT, with 2,473 transplanted with liver from deceased donors (DD) and 6,942 from living donors (LD). The mean age was 52.2±9.0 years. The majority of LT was performed on patients in their 50s (n=4290, 45.6%) and 0.9% (n=84) of the LT was performed on patients aged over 70 years. The overall in-hospital mortality was 6.3%, and the 3-year mortality was 11.3%. The in-hospital mortality included, 13.5% associated with DDLT and 3.7% involved LDLT. When compared with that for patients aged 51 to 55 years, the risk of death among recipients aged over 70 years was about four-fold higher after adjusting for baseline liver disease (OR 4.1; 95% CI 2.21-7.58), and was nearly 3 fold higher after adjusting for baseline liver disease and perioperative complications (OR 2.92; 95% CI 1.37-6.24). And the cost of LT increased significantly with age. Conclusions The data shows that age remains an important risk factor for LT, suggesting that LT should be considered with caution in elderly recipients.
