394 Association of Pre-Existing Medical Conditions in Burn Morbidity and Mortality

There are many patients that survive their initial burn trauma, however subsequently die during the admission to a burn unit. There are known risk factors of mortality: Age, total body surface area, and inhalation injury. There are increasing numbers of patients who have pre-existing medical conditions who are admitted for burn injuries. The majority of these patients are receiving appropriate management for their medical conditions. However we feel that these conditions put patients at an increased risk of morbidity and mortality. A retrospective assessment was made of the period of 2013 - 2017, of all patients who died during their admission. The data was assessed for: Age, total body surface area, and inhalation injury. The previous medical history of all patients was checked for cardiovascular, pulmonary, renal and diabetes in all patients that died. There were 46 patients who died once admitted, with 20 females and 26 males. Inhalation injury as the cause of death was found in 4 patients, a combination of burns and inhalation injury in 19 patients and only burns in 23 patients. The average of all patients in the mortality group was 55 years old. The mean age for inhalation was 59, inhalation and burns was 47 and burns were 62 years old. The patients who died within three days of admission were either younger patients with large total body surface area burns or geriatric patients with typically smaller burns and often an associated inhalation injury. In geriatric patients >65 years old, a higher mortality rate was noted in smaller burns when compared to adults 18–64. Inhalation injury was associated with a significant increase in mortality in all age groups. If a patient had 2 or more of the noted pre-existing medical conditions, there was a higher rate of mortality in all age groups. Additionally having >2 pre-existing medical conditions correlated to longer hospital admissions in adults 18–64 before they died. The data suggests that there is an association between mortality and pre-existing medical illness in all-adult age groups. Association between mortality and previous medical history in adult burn patients.
