  1. From this table, the likelihood of transfusion were compared for different variables and expressed as hazard ratios. This was higher for patients who suffered inhalation injury, TBSA > 20%, low BMI (<18.5 kg/m2), patients admitted to the ICU, low Hemoglobin level, patients with features of infection and those that underwent surgery
  2. Despite the Hazard ratios, only patients with; percentage TBSA injured >20%, BMI below normal, pre-existing illnesses, abnormal white cell counts during admission and admission to the ICU showed statistical significance (p < 0.05)
