Abstract

INTRODUCTION: Autologous breast reconstruction (ABR) has increased in recent decades, although concerns for access remain. As such, our goal is to trend national demographics and operative characteristics of ABR in the United States.METHODS: Using the National Inpatient Sample, 2016-2019, the International Classification of Disease, Tenth Edition codes identified adult female encounters undergoing ABR. Demographics and procedure-related characteristics were recorded. Discharge weights generated national estimates. Statistical analysis included univariate testing and multivariate regression modeling.RESULTS: A total of 52,910 weighted encounters met the criteria (mean age, 51.5 ± 10.0 years). Autologous breast reconstruction utilization increased (Delta = +5%), 2016-2019, primarily driven by a rise in deep inferior epigastric perforator (DIEP) reconstructions (Delta = +28%; incidence rate ratio [IRR], 1.070; P < 0.001), which were predominant throughout the study period (69%). More recent surgery year, bilateral reconstruction, higher income levels, commercial insurance, and care in the South US region increased the odds of DIEP-based ABR (P = 0.036). Transverse rectus abdominis myocutaneous flaps, bilateral reconstructions, higher comorbidity levels, and experiencing complications increased the length of stay (P = 0.038). Most ABRs (75%) were privately insured. The rates of immediate reconstructions increased over the study period (from 26% to 46%; IRR, 1.223; P < 0.001), as did the rates of bilateral reconstructions (from 54% to 57%; IRR, 1.026; P = 0.030). The rates of ABRs performed at teaching hospitals remained high (90% to 93%; P = 0.242).CONCLUSIONS: As of 2019, ABR has become more prevalent, with the DIEP flap constituting the most common modality. With the increasing ABR popularity, efforts should be made to ensure geographic and financial accessibility.
