Cost Comparison of Digital Nerve Repair Techniques.

Abstract

Direct cost comparison of nerve allograft with other techniques for repairing short digital nerve gaps are lacking. This study compares the costs of various techniques for digital nerve repair, anticipating significant cost increases for allograft implants. The State Ambulatory Surgery and Services Database for Florida, New York, and Wisconsin from 2015-2020 was used. Patients with primary repair, short autograft, conduit, and allograft were compared along total, surgical supply, operating room (OR), and anesthesia charges. Among 5,009 patients were 2,967 primary nerve repairs (59.2%), 77 autografts (1.5%), 1,647 conduits (32.9%), and 318 allografts (6.3%). 2,886 patients were male (57.6%) with mean age 40.4 ± 16.3 years. Over the study period, primary repairs decreased (63.9% in 2015 to 56.3% in 2020) while allografts increased significantly (8.8% in 2018 to 12.6% in 2020).Median total charges significantly varied across procedures, with the most expensive being allograft ($35,295), followed by conduit ($25,717), autograft ($24,749), and primary repair ($18,767). On multivariable regression, allograft is significantly more expensive than autograft for total charges by $11,224 (95CI: $4,196-$18,252) and supply charges by $10,484 (95CI: $6,073-$14,896), but not for OR or anesthesia charges. Flexor tendon repair was associated with greater total, OR, and anesthesia charges but similar supply charges. Nerve allograft is the most expensive digital nerve repair technique most likely due to the cost of the implant. To minimize health care expenditure and ensure equitable patient access, surgeons should consider this cost along with clinical factors in choosing digital nerve repair techniques.
