Abstract

Direct-to-implant breast reconstruction is an attractive choice for appropriately-selected patients, as a single-stage procedure can enhance global metrics of care. In an era of high-value healthcare, therefore, it is important to investigate utilization of such procedures. This study investigated direct-to-implant trends over the past decade on a nationwide basis.This was a retrospective investigation of direct-to-implant reconstruction between 2010-2018 in the United States, using the National Inpatient Sample (NIS) database. All study analyses were undertaken using Stata v15.0.The weighted sample included 287,093 women who underwent implant-based reconstruction between 2010-2018, of whom 43,064 (15%) underwent direct-to-implant reconstruction. Across the study period, the proportion of direct-to-implant procedures significantly increased (p=0.03), relative to staged and delayed implant-based procedures. While direct-to-implant patients were younger, more likely to be white and privately-insured, the proportion of non-white, publicly-insured patients undergoing direct-to-implant reconstruction significantly increased by 2018 (p<0.05). Furthermore, direct-to-implant utilization amongst Medicaid patients increased at 2.2 times the rate in Medicaid expansion states compared to non-expansion states. Direct-to-implant patients had significantly higher APR-DRG risk scores in 2018 than in 2010 (p=0.02), indicating expanding clinical indications for this procedure. Direct-to-implant reconstruction had significantly lower inpatient charges than staged procedures (p=0.03), when considering expander placement and expander-implant exchange.Overall, utilization of direct-to-implant breast reconstruction has significantly increased over the past decade, facilitated by expanding clinical indications and improved insurance coverage. However, certain disparities continue to exist. Further work should investigate drivers of disparities to allow continued expansion of direct-to-implant reconstruction as clinically appropriate.
