Real-world Use of AlloDerm Acellular Dermal Matrix in Head and Neck Procedures in the United States.

Background: Real-world literature evaluating the use of AlloDerm SELECT Regenerative Tissue Matrix in head- and neck-related procedures is limited. To inform patient care decisions, this study evaluated healthcare resource utilization (HCRU) in US adults undergoing head- and neck-related procedures using AlloDerm.

Methods: A retrospective claims analysis was conducted using MarketScan Commercial and Medicare Supplemental Databases (study period: October 1, 2015, to March 31, 2022; index period: November 1, 2015, to March 1, 2022). Adults aged 18 years or older with (1) medical claims for AlloDerm and a skin substitute on the same day during the index period, (2) a head/neck procedure diagnostic code, and (3) 30 or more days of continuous enrollment before and after first AlloDerm use index date. Descriptive statistics were used to describe surgery types and 30-day follow-up reoperations, graft complications, and all-cause HCRU.

Results: Among 431 patients (51.7% women), mean (SD) age was 52.2 (15.8) years. AlloDerm was most used with oral cavity reconstruction (35.3%), septal perforation repair/rhinoplasty (16.5%), and parotidectomy (13.0%). Most procedures were performed in outpatient settings (hospital, 90.0%; ambulatory surgical center, 8.6%). Over 30 days, less than 1% of patients (4 of 431) required reoperation with AlloDerm; 0.5% (2 of 431) had graft-related complications. Most (75.6%) patients had an outpatient visit; few had an emergency room visit (7.9%) or inpatient claim (3.0%).

Conclusions: Real-world evidence indicates that AlloDerm is used in head- and neck-related procedures in US adults, particularly oral reconstruction. Postprocedure complications and reoperations are uncommon during the follow-up period.
