<Tr> <Td> Inhalation </Td> <Td> 23% </Td> </Tr> <P> 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 . </P> <P> A number of complications may occur, with infections being the most common . In order of frequency, potential complications include: pneumonia, cellulitis, urinary tract infections and respiratory failure . Risk factors for infection include: burns of more than 30% TBSA, full - thickness burns, extremes of age (young or old), or burns involving the legs or perineum . Pneumonia occurs particularly commonly in those with inhalation injuries . </P> <P> Anemia secondary to full thickness burns of greater than 10% TBSA is common . Electrical burns may lead to compartment syndrome or rhabdomyolysis due to muscle breakdown . Blood clotting in the veins of the legs is estimated to occur in 6 to 25% of people . The hypermetabolic state that may persist for years after a major burn can result in a decrease in bone density and a loss of muscle mass . Keloids may form subsequent to a burn, particularly in those who are young and dark skinned . Following a burn, children may have significant psychological trauma and experience post-traumatic stress disorder . Scarring may also result in a disturbance in body image . In the developing world, significant burns may result in social isolation, extreme poverty and child abandonment . </P>
