Abstract
No study has examined associations between physician volume or hospital volume and survival in patients with liver malignancies in the hepatitis B virusendemic areas such as Taiwan This study was to examine the effect of hospital and surgeon volume on 5year survival and to determine whether hospital or surgeon volume is the stronger predictor in patients with hepatocellular carcinoma after hepatic resection in TaiwanUsing the 1997–1999 Taiwan National Health Insurance Research Database and the 1997–2004 Cause of Death Data File we identified 2799 patients who underwent hepatic resection and 1836 deaths during the 5year followup period The Cox proportional hazard regressions were performed to adjust for patient demographics comorbidity physician and hospital characteristics when assessing the association of hospital and surgeon volume with 5year survivalWhen we examined the effect of physician and hospital volumes separately both physician and hospital volumes significantly predicted 5year survival after adjusting for characteristics of patient surgeon and hospital However after we adjusted for characteristics of physician and hospital only physician volume remained a significant predictor of the 5year survival
