Background: Traditionally, patients with breast reconstruction (BR) were hospitalized at least one day postoperatively. However, new trends suggest that outpatient surgery is a viable and safe alternative. This study aims to assess trends among patients with breast cancer who underwent outpatient mastectomy alone, with immediate BR (IBR) or delayed BR (DBR).
Methods: A retrospective analysis of the 2013-2019 ACS NSQIP® database was conducted. All women who underwent outpatient mastectomy were included in this study. The cohort was divided as follows: (1) mastectomy without BR, (2) IBR, and (3) DBR. A Cochran-Armitage test and adjusted multivariable logistic regression models were performed to evaluate linear trends over time within groups, and overall and pairwise comparisons between groups across the years, respectively.
Results: A total of 84,954 women were included in this study. Overall, 54.9%, 16.2%, and 28.9% underwent mastectomy without BR, IBR, and DBR, respectively. From the BR groups, the majority had implant placement. A significant difference in incidence trends between the three groups was evidenced over time (p<0.001). The greatest increase was evidenced in the IBR group and the lowest in the mastectomy without BR group.
Conclusion: In this cohort of patients, a significant difference in linear trends was evidenced over time within and between the three groups. Our results suggest that outpatient IBR procedures are increasing in a greater proportion compared to other surgical approaches. Further studies are required to better characterize this population and comprehend the decision-making process toward a surgical procedure within each of the three groups.
