Background-Reasons underlying disparities in outcomes in liver resections between patients who are African American and patients who are not are poorly understood. Methods-An observational longitudinal cohort study was performed. Clinical data were collected from medical records of 166 patients (59 African American, 107 not) undergoing partial hepatectomy between 2004 and 2012. Univariate and multivariate analyses were performed. Results-African Americans patients undergoing partial hepatectomy were more likely to be female, heavier, have hemangiomas or adenomas, and have hepatic steatosis on explant. Intraoperatively, African Americans had longer surgical times, higher estimated blood loss, and greater use of blood products. Major postoperative complications were significantly more common in African Americans. Multivariable modeling demonstrated that race, history of hepatitis C, and estimated blood loss were the only variables that were independently associated with a major complication; however, baseline serum creatinine level was the only variable that significantly modified the effect of race on complications. Conclusions-African Americans with normal serum creatinine levels had a similar rate of complication to patients who were not African American, but as the baseline serum level of creatinine increased, the odds ratio for a complication developing increased dramatically in the African American patients, suggesting that the disparities seen are predominantly driven by a subset of African American patients who have preexisting renal insufficiency.
