AIM: To assess the amount of allograft used in the past treatment of major burns and calculate a figure to guide estimation of the quantity of allograft required to treat future patients and aid resource planning. METHODS: A retrospective observational study. Records of 143 patients treated with major burns at a regional centre, from January 2004 to November 2008 were accessed with biometric data and quantity of allograft used being recorded. This data was used to calculate an allograft index (cm² allograft used/burn surface area (cm²)) (AI) for each patient. RESULTS: 112 of the 143 patients had complete sets of data, of the 112, 89 patients survived the initial stay in hospital. For all data average AI=1.077 ± 0.090. AI varied according to burn % area with burns < 40% requiring 0.490 cm² allo/cm²burn, increasing in a logarithmic fashion (R²=0.995) for burn areas > 40%. CONCLUSIONS: The ability to estimate deceased donor skin requirements based on % body surface area affected is important in the care planning for patients with major burns. Our findings of 0.5 cm² allograft/cm² burn for injuries less than 40% TBSA, increasing to 1.82 cm² allograft/cm² burn for injuries up to 80% TBSA can be used for planning purposes for individual services and for burn disaster planning.
