Background: Prognostic Burn Index (PBI) is a commonly utilized as a prognostic indicator for severe burn patients in Japan. Herein, we investigated the utility of a novel PBI that incorporates inhalation injury as a factor into the existing PBI.
Methods: We enrolled burn patients hospitalized between 2008 and 2023. Patients with inhalation injury alone or those with cardiopulmonary arrest on admission were excluded.
Result: We enrolled 252 patients, with a median age of 54 years and a total burn area (TBSA) of 15%, including second-degree burns (9%). Third-degree burns were not included. There were 42 non-survivors (17%) and 104 patients had inhalation injuries (41%). The survivors and non-survivors showed significant differences in age, TBSA, presence of second or third-degree burns, and airway burns. Multiple logistic regression analysis revealed that inhalation injuries contributed 19.33 times more than the standard BI. Therefore, we introduced a new PBI that added 20 to PBI when inhalation injuries were present. The area under the curve values for each index were 0.919 for PBI, 0.923 for Baux score, 0.941 for the revised Baux score, 0.931 for ABSI, 0.9123 for BOBI, and 0.9547 for our new PBI.
Conclusion: Our new PBI is a useful prognostic index for burn patients.
