Hospital Transfers for Digit Replants as Cost Saving and Safe While Access to Replantation Procedures Remains Limited.

BACKGROUND Finger replantation outcomes are influenced both by injury characteristics and by hospital and patient factors, such as hospital type/location and patient gender or insurance. Finger replantation success rates have been shown to be higher at hospitals with higher volumes of finger replants. This study examines the hospital and patient factors that influence hospital transfer and successful replantation in patients experiencing traumatic finger amputation. METHODS A total of 5219 patients were identified in the 2008-2015 National Inpatient Sample (NIS) as having experienced traumatic finger amputation with attempted replantation. Hospital transfer and replant outcomes were compared with variables such as patient demographics and hospital characteristics using χ2 tests, t tests, ANOVA, and logistic regression. RESULTS Traumatic digit amputation patients were most likely to be transferred to medium or large hospitals in urban areas. Hospital transfer was 1.5 times more likely in White patients than Black or Hispanic patients and 1.6 times more likely in middle income quartile patients than the top income quartile. Postreplant amputation was more likely in patients in the lower three income quartiles, on Medicare, of older age, or with more chronic conditions. Hospital transfer was not associated with changes in the probability of requiring amputation after replantation but was associated with a decreased cost of $5000. CONCLUSIONS Hospital transfers for finger replants are safe with respect to replant failure rates and cost-effective, saving $5000 per procedure. Gaps in equitable access to care remain, warranting further study to improve health equity.
