Abstract | Importance: Given that 40% of hand function is achieved with the thumb, replantation of traumatic thumb injuries is associated with substantial quality-of-life benefits. However, fewer replantations are being performed annually in the US, which has been associated with less surgical expertise and increased risk of future replantation failures. Thus, understanding how interfacility transfers and hospital characteristics are associated with outcomes warrants further investigation. Objective: Design, Setting, and Participants: This cross-sectional study used data from the US National Trauma Data Bank from 2009 to 2016 for adult patients with isolated traumatic thumb amputation injury who underwent revision amputation or replantation. Data analysis was performed from May 4, 2020, to July 20, 2020. Exposures: Interfacility transfer, defined as transfer of a patient from 1 hospital to another to obtain care for traumatic thumb amputation. Main Outcomes and Measures: Results: Of 3670 patients included in this analysis, 3307 (90.1%) were male and 2713 (73.9%) were White; the mean (SD) age was 45.8 (16.5) years. A total of 1881 patients (51.2%) were transferred to another hospital; most of these patients were male (1720 [91.4%]) and White (1420 [75.5%]). After controlling for patient and hospital characteristics, uninsured patients were less likely to have thumb replantation attempted (odds ratio [OR], 0.61; 95% CI, 0.47-0.78) or a successful replantation (OR, 0.64; 95% CI, 0.49-0.84). Interfacility transfer was associated with increased odds of replantation attempt (OR, 1.34; 95% CI, 1.13-1.59), with 13% of the variation at the hospital level. Interfacility transfer was also associated with increased replantation success (OR, 1.23; 95% CI, 1.03-1.47), with 14% of variation at the hospital level. Conclusions and Relevance: In this cross-sectional study, interfacility transfer and particularly hospital-level variation were associated with increased thumb replantation attempts and successes. These findings suggest a need for creating policies that incentivize hospitals with replantation expertise to provide treatment for traumatic thumb amputations, including promotion of centralization of replantation care.
