Autologous Breast Reconstruction is Associated with Lower 90-day Readmission Rates.

backgroundBreast reconstruction is associated with improved quality of life after mastectomy. Options for breast reconstruction include autologous and implant-based methods. Although autologous reconstruction is more technically challenging and requires longer operative time, it is thought of as the gold standard. Our study examined differences in 90-day readmission rates between implant-based and autologous breast reconstruction using discharge data from the National Readmission Database, Healthcare Cost and Utilization Project, and Agency for Healthcare Research and Quality.

methodsThe National Readmission Database was used to identify patients undergoing postmastectomy breast reconstruction. Patients were selected using ICD-10 PCS codes linked to autologous and implant-based reconstruction. Ninety-day readmission rates were determined. After matching the two groups on a 1:1 basis for baseline comorbidities and demographics, a multivariable logistic regression analysis was performed to variables associated with higher readmission rates.

resultsThe leading diagnoses associated with readmissions were infectious and pulmonary. After one to one matching, autologous breast reconstruction, private insurance versus Medicaid, and income quartile 4 versus 1 were all less likely to be readmitted within 90 days of discharge. Patients with a high Charlson index and those with a longer length of initial hospital stay are significantly more likely to be readmitted within 90 days.

conclusionsPatients undergoing autologous breast reconstruction were 23% less likely to be readmitted within 90 days from discharge. Fewer comorbidities, shorter length of hospital stay, and higher socioeconomic status are also associated with lower readmission rates following breast reconstruction.
