OBJECTIVE We sought to determine the reliability of surgeon-specific postoperative complication rates after colectomy. BACKGROUND Conventional measures of surgeon-specific performance fail to acknowledge variation attributed to statistical noise, risking unreliable assessment of quality. METHODS We examined all patients who underwent segmental colectomy(More)
OBJECTIVE To examine the magnitude and sources of inpatient cost variation for kidney transplantation. METHODS We used the 2005-2009 Nationwide Inpatient Sample to identify patients who underwent kidney transplantation. We first calculated the patient-level cost of each transplantation admission and then aggregated costs to the hospital level. We fit(More)
AIM To determine whether hospital characteristics predict cirrhosis mortality and how much variation in mortality is attributable to hospital differences. METHODS We used data from the 2005-2011 Nationwide Inpatient Sample and the American Hospital Association Annual survey to identify hospitalizations for decompensated cirrhosis and corresponding(More)
BACKGROUND Currently, transplant patients have limited metrics available to understand transplant center quality. Graft and patient survival do not capture the patient experience, and patients may use more general consumer assessments of hospital care to help select transplant centers. We evaluated whether consumer assessments of hospital quality correlate(More)
BACKGROUND Racial/ethnic disparities in liver disease and cirrhosis are well established. Cirrhosis mortality is improving overall despite vast differences between hospitals. We sought to understand the hospital characteristics where minorities seek care, whether disparities in cirrhosis mortality persist, and determine how hospital differences contribute(More)
