Same Day Discharge After Mastectomy and Immediate Implant-Based Breast Reconstruction

Abstract

Introduction Currently, overnight admission after immediate implant-based breast reconstruction (IBR) is the standard of care. Our study aims to analyze the safety, feasibility, and outcomes of immediate IBR with same-day discharge as compared with the standard overnight stay. Methods The 2015–2020 National Surgical Quality Improvement Program database was reviewed to identify all patients undergoing mastectomy with immediate IBR for malignant breast disease. Patients were stratified into study (patients discharged day of surgery) and control (patients admitted after surgery) groups. Patient demographics, comorbidities, surgical characteristics, implant type, wound complications, readmission, and reoperation rates were collected and analyzed. Univariate and multivariate logistic regression was used to determine independent predictors of same-day discharge versus admission. In addition, Pearson χ2 test was used for comparison of proportions and t test was used for continuous variables unless distributions required subsequent nonparametric analyses. Statistical significance was defined as a P value less than 0.05. Results A total of 21,923 cases were identified. The study group included 1361 patients discharged same day and the control group included 20,562 patient s admitted for average of 1.4 days (range, 1–86). Average age was 51 years for both groups. Average body mass index for the study group 27 and 28 kg/m2 for the control group, respectively. Total wound complication rates were similar (4.5% study, 4.3% control, P = 0.72). Reoperation rates were lower with same-day discharge (5.7% study, 6.8% control, P = 0.105), though not statistically significant. However, same-day discharge patients had a significantly lower readmission rate compared with the control (2.3% study, 4.2% control, P = 0.001). Conclusion National Surgical Quality Improvement Program data analysis over a 6-year period reveals that immediate IBR with same-day discharge is associated with a significantly lower readmission rate when compared with the standard overnight stay. The comparable complication profiles show that immediate IBR with same-day discharge is safe, potentially benefiting both patients and hospitals.
