BACKGROUND: Despite advances in surgical technique and perioperative management, pneumonectomy remains associated with significant morbidity and mortality. The purpose of this study was to examine the impact of annual institutional volume of anatomic lung resections on outcomes after elective pneumonectomy.
METHODS: We evaluated all patients who underwent elective pneumonectomy from 2005 to 2014 in the National Inpatient Sample. Patients less than 18 years of age, or with trauma-related diagnoses, mesothelioma, or a nonelective admission were excluded. Hospitals were divided into volume quartiles based on annual institutional anatomic lung resection caseload. We studied the effect of institutional volume on inhospital mortality, complications, and failure to rescue, as well as costs and length of stay.
RESULTS: During the study period, an estimated 22,739 patients underwent pneumonectomy, with a reduction in national mortality from 7.9% to 5.5% (P trend = .045). Compared with the highest volume centers, operations performed at the lowest volume hospitals were associated with 1.74 increased odds of mortality (95% confidence interval, 1.14 to 2.66). Despite similar odds of postoperative complications, low volume hospital status was associated with increased failure to rescue rates (18.3% vs 12.7%, P = .024) and adjusted odds of mortality (1.70; 95% confidence interval, 1.09 to 2.64) after any complication.
CONCLUSIONS: High volume hospital status is strongly associated with reduced mortality and failure to rescue rates after pneumonectomy. Efforts to centralize care or disseminate best practices may lead to improved national outcomes for this high-risk procedure.
