Abstract

Background: In Japan, microsurgical skill development and a system to transfer patients to an appropriate hospital for upper extremity amputation have been promoted; however, information about trends of replantation is limited. Therefore, the aim of this study was to clarify the trends in the treatment for upper extremity amputation using the Japan Trauma Data Bank (JTDB). Methods: Data derived from JTDB (2004–2015) were used to quantify trends in the volume of replantation for upper extremity amputation including finger amputation. Trauma was diagnosed based on the Abbreviated Injury Scale code; a subgroup of patients who underwent replantation was delineated. We investigated patient demographics, infection rate, and characteristics of treating facilities. Results: A total of 1240 patients underwent upper extremity amputation. Among these, 510 (41.1%) underwent replantation, and the rate of replantation did not change over the study period. The average age of patients who underwent or did not undergo replantation was 45.5 and 47.2 years, respectively. The proportion of the patients who were transferred to another hospital for treatment significantly decreased between 2004 (28.5%) and 2015 (16.3%) (P < 0.01). Time taken for transfer from the accident site to hospitals increased. The rate of patients who underwent replantation differed among different hospitals; however, higher-volume hospitals were more likely to perform replantation. Conclusion: The rate of patients transferred to another hospital decreased between 2004 and 2015; however, the rate of patients who underwent replantation remained unchanged. This suggests that the number of patients who were transported directly from the accident site to an appropriate hospital has increased, whereas the indication for care in each hospital remains unchanged. Common criteria for amputations are needed to address the differing rates of replantation among hospitals.
