There are still no algorithms for the treatment of patients with thermal injuries based on specialized mortality prediction indices due to the absence of relevant stratification models.
OBJECTIVE
To develop a mortality risk stratification model for patients with thermal injuries based on the Revised Frank Index and compare this tool with stratification models based on other specialized mortality prediction indices.
MATERIAL AND METHODS
To develop a stratification model based on the revised Frank Index (RFI), we analyzed these scores for 399 patients with skin burns using the following equation: ∑ = age (years) + S burns (% of BSA) + 3×S deep burns (% of BSA) + 30 (for inhalation injury). To compare patient stratification models based on the Baux, Frank and Abbreviated Burn Severity Index (ABSI), all these scales were calculated for patients.
RESULTS
The number of deaths increased in each subsequent stratification group compared to the previous one. However, there were no significant differences in the number of deaths and risk of mortality in models based on Baux and IF indices. The number and risk of death were significantly different in all groups only in our RFI-based stratification of patients.
CONCLUSION
The developed RFI-based patient stratification model provides a more accurate prediction compared to Baux, IF and ABSI values. Thus, RFI is perspective for further development of treatment algorithms.
