Thirty-Day Nonindex Readmissions and Clinical Outcomes After Cardiac Surgery.

ABSTRACT:

Background

With increasing emphasis on readmissions as an important quality metric, there is an interest in regionalization of care to high-volume centers. As a result, care of readmitted cardiac surgery patients may be fragmented if readmission occurs at a nonindex hospital. This study characterizes the frequency, risk factors, and outcomes of nonindex hospital readmission after cardiac surgery.

Methods

In this multicenter, population-based, nationally representative sample, we used weighted 2010-2015 National Readmission Database claims to identify all US adult patients who underwent 2 of the major cardiac surgeries, isolated coronary artery bypass grafting (CABG) or isolated surgical aortic valve replacement (SAVR), during their initial hospitalization. We examined characteristics, predictors, and outcomes after nonindex readmission.

Results

Overall, 1,070,073 procedures were included (844,206 CABG and 225,866 SAVR). Readmission at 30 days was 12.8% for CABG and 14.5% for SAVR. Nonindex readmissions accounted for 23% and 26% at 30 days; these were primarily noncardiac in etiology. The proportion of nonindex readmissions did not change significantly from 2010 to 2015. For CABG and SAVR, in-hospital mortality (adjusted odds ratios of 1.26 and 1.37, respectively) and major complications (odds ratios of 1.17 and 1.25, respectively) were significantly higher during nonindex versus index readmission, even after adjusting for patient risk profile, case mix, and hospital characteristics. Older age, higher income, and increased comorbidity burden were all independent predictors of nonindex readmission.

Conclusions

A considerable proportion of patients readmitted after cardiac surgery are readmitted to nonindex hospitals. This fragmentation of care may account for worse outcomes associated with nonindex readmissions in this complex population.

Project description:BackgroundPediatric bone and soft tissue sarcomas are rare; therefore, national registries are essential tools for orthopedic oncology research. Past studies provide excellent data on long-term prognosis and survival trends but fail to examine treatment-specific morbidity. The aim of this study is to use a national registry to describe patient demographics, comorbidities, and adverse events in the first thirty days following surgical management of pediatric bone and soft tissue sarcomas.MethodsA retrospective review of patients in the American College of Surgeons National Surgical Quality Improvement Program-Pediatrics database (NSQIP-P) was performed. The cohort was partitioned by tumor origin (bone versus soft tissue) and tumor location (axial versus appendicular).ResultsOne-hundred ninety-two patients were identified. Bone sarcomas were more common (71.9%) and predominately appendicular (62.3%), while soft tissue sarcomas were predominately axial (77.8%). The overall complication rate was 8.9%. The most frequent etiologies were wound dehiscence (3.6%) and infectious complications such as surgical site infections (2.6%), pneumonia (1.6%), urinary tract infections (1.6%), and C. diff colitis (1.0%). Twenty-four percent of patients experienced bleeding requiring transfusion. The unplanned readmission rate was 12.5% (3.6% related to principle procedure), and the unplanned reoperation rate was 4.7% (4.2% related to principle procedure). The mortality rate was 1.0%. Neoadjuvant chemotherapy was associated with higher rates of wound dehiscence and infectious complications. There were no differences in adverse events with respect to tumor origin or location.ConclusionApproximately 1 in 11 pediatric patients will experience a complication in the first thirty days following surgery. However, perioperative mortality remains low. This study represents the first comprehensive review of pediatric bone and soft tissue sarcoma surgery in the NSQIP-P database. As the case volume of NSQIP-P continues to grow, NSQIP-P has the potential to become a powerful tool for pediatric orthopedic oncology research.
