 The prognosis is worse in those with larger burns , those who are older , and those who are females . The presence of a smoke inhalation injury , other significant injuries such as long bone fractures , and serious co @-@ morbidities ( e.g. heart disease , diabetes , psychiatric illness , and suicidal intent ) also influence prognosis . On average , of those admitted to United States burn centers , 4 % die , with the outcome for individuals dependent on the extent of the burn injury . For example , admittees with burn areas less than 10 % TBSA had a mortality rate of less than 1 % , while admittees with over 90 % TBSA had a mortality rate of 85 % . In Afghanistan , people with more than 60 % TBSA burns rarely survive . The Baux score has historically been used to determine prognosis of major burns . However , with improved care , it is no longer very accurate . The score is determined by adding the size of the burn ( % TBSA ) to the age of the person , and taking that to be more or less equal to the risk of death . Burns in 2013 resulted in 1 @.@ 2 million years lived with disability and 12 @.@ 3 million disability adjusted life years .
