AbstractThis study provides objective data on the practice of allograft usage in severely burned patients. Furthermore, gaps in our knowledge are identified, and areas for further research are delineated. Using an institutional review board-approved protocol, active duty military patients injured while deployed in support of overseas contingency operations and treated at our burn center between March 2003 and December 2010 were identified. Their electronic medical records were reviewed for allograft use, TBSA burned, injury severity score, anatomic distribution of burns, operative burden, length of stay, transfusions, and outcome. Among 844 patients, 112 (13.3%) received allograft and 732 (86.7%) did not. The amount of allograft used per patient varied and was not normally distributed (median, 23.5; interquartile range, 69.5). Patients received allograft skin an average of 12.75 times during their admission. Allografted patients sustained severe burns (μ, 53.8% TBSA); most were transfused (71.2%) and grafted frequently, averaging every 7.45 days. Most commonly, allograft was placed on the extremities (66.5%) followed by the trunk (44.2%); however, the vast majority of allografted patients also had concomitant burns of the head (91.1%) and hands (87.5%). All-cause mortality among the allografted patients was 19.1%. In conclusion, allograft is commonly used in the surgical treatment of severe burns. Although there are no anatomic limitations to allograft placement, there are distinct patterns of use. Given the role of allograft in the acute management of large burns, there is need for further investigation of its effect on mortality, morbidity, and antigenicity.
