Abstract
Introduction
Despite the growing spotlight on value-based care and patient safety, little is known about the influence of patient-, reconstruction-, and facility-level factors on safety events following breast reconstruction. The purpose of this study is to characterize postoperative complications in light of hospital-level risk factors.
Methods
Using the National Inpatient Sample, all patients who underwent free flap and prosthetic breast reconstruction from 2012 to 2014 were identified. Predictor variables included patient demographic and clinical characteristics, type and timing of reconstruction, annual hospital reconstructive volume, hospital bed size, hospital setting (rural vs. urban), and length of stay. Patient safety indicators (PSIs) were based on the Agency for Healthcare Research and Quality’s designation of preventable hospital complications: venous thromboembolism, bleeding, wound complications, pneumonia, and sepsis. Logistic models were used to analyze outcomes.
Results
The sample included 103,301 women, of which 27,695 (26.8%) underwent free flap reconstruction. 3.6% of patients experienced ≥ 1 PSI, most commonly wound PSI (4.9% and 2.5% for free flap and prosthetic reconstruction, respectively). Significant predictors of PSIs included rural setting (p < 0.01) and Elixhauser score ≥ 4 (p < 0.01) for the free flap group, and delayed reconstruction (p < 0.01) for the prosthetic group. Annual reconstructive facility volume was not associated with increased odds of PSIs in either prosthetic or free flap reconstruction (p > 0.05).
Conclusion
PSIs were associated with rural hospitals and greater comorbidities for patients undergoing reconstruction with free flaps. Annual reconstructive facility volume was not associated with adverse inpatient outcomes with either method of reconstruction.
