The burn unit experience at Grady Memorial Hospital: 844 cases

Between February 20, 1987 and July 13, 1990, 844 patients were admitted to the Grady Memorial Hospital Burn Unit. Mean age was 25.5 years, mean burn size 16.5% total body surface area, mean survivor hospital length of stay 15.9 days, and an overall survival 90.5%. Seventy-three percent were male. One half of the burns were less than 10% total body surface area. Almost half (48.5%) of the patients had flame burns, which accounted for 88.8% of the 80 deaths. The peak burn incidence occurred in infants and children as a result of scalds. If those with toxic epidermal necrolysis (n = 5), those without skin injury (n = 13), and those who were allowed to die (n = 16) are excluded, survival was 92.2%. Survival in 62 patients with inhalation injury (55.23%) was significantly less than that in 474 patients without inhalation injury (98.10%) (p less than 0.0001). The three variables--age, burn size, and inhalation injury--each influenced survival significantly but appeared to be dependent on each other; all three tended to increase or decrease together. Logistic regression equations to predict survival were developed.
