Examination of several factors associated with the prognosis in burn patients

Abstract

In many cases, severe burn patients may have poor prognosis. Furthermore, treatment strategy for the patient just after burn injury may affect the vital prognosis so much. The prognostic burn index (PBI) is one of the factors associated with the prognosis, but there may be several another factors in clinically. Therefore, we investigated the influences for the factors associated with the prognosis including PBI to decided the therapeutic strategy for severe burn patient retrospectively. 69 patients (6 months to 95 years old) who were transported by ambulance to the medical emergency center in our hospital were designed. Regarding the analysis, a multivariate logistic analysis was conducted with vital prognosis as the objective variable, and explanatory variables were age, gender, source of injury, self-injury / external wound, number of surgeries and PBI. Furthermore, a ROC curve (Receiver Operating Characteristic curve) was obtained from the vital prognosis and PBI values. As a result, PBI was the only factor to affect the vital prognosis significantly (odds ratio : 1.33, p < 0.05). The mortality rate was 100% when PBI was 93.675 or greater. It may be thought that PBI is very important factor to select either early surgical excision or conventional therapy for severe burn patient.
