Patient selection: major burn injury, age 16 to 65 years of age
Parameters:
(1) Abbreviated Burn Severity Index (ABSI) of Tobiasen et al
(2) serum albumin on admission (time = 0)
(3) serum albumin at 24 hours after admission (time = 24)
Poor prognostic factors in major burn:
(1) ABSI >= 10 ("over 9")
(2) serum albumin at 0 hours < 3.5 g/dL
(3) serum albumin at 24 hours < 2.4 g/dL
where:
• An ABSI of 8 or 9 indicates a serious burn.
Performance:
• The area under the ROC curve was 0.94 for the ABSI.
• The area under the ROC curve was 0.86 for serum albumin at 0 hours.
• The area under the ROC curve was 0.92 for serum albumin at 24 hours.
• Combining the ABSI with one of the serum albumin measures increased AROC to 0.97.
