BACKGROUND: Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality worldwide. Liver resections and transplantations have increasingly become feasible options for potential cure. These complex surgeries are inherently associated with increased rates of readmission. In the meanwhile, hospital readmission rates are rapidly becoming an important quality of care metric. Therefore, it is very important to understand the effect of 30-day readmission on mortality and the factors associated with increased 30- and 90-day mortality rates. METHODS: This is a retrospective cohort study utilizing data from the National Cancer Database. Patients included were 18 years or older who underwent liver resection or liver transplantation for HCC between 2003 and 2011. Our primary outcomes of interest were 30- and 90-day mortality rates. Our primary independent variable of interest was 30-day readmission. RESULTS: 16 658 patients underwent either a liver resection or transplantation for HCC between 2003 and 2011. For patients with liver transplantations, increased readmission rates were associated with lower risks of 30-day mortality (P = .012) but a trend toward higher 90-day mortality (P = .057). Patients who underwent liver resection for HCC also demonstrated increased readmission rates to be associated with lower risk of 30-day mortality (P = .014) but higher 90-day mortality (P ≤ .001). CONCLUSION: This is the only study to utilize a national database to investigate the association between readmission rates and mortality rates of both liver transplantations and resections for patients with HCC. We demonstrate 30-day readmission to show no increase in 30-day mortality, but rather higher 90-day mortality.
