Abstract

The purpose of this study was to evaluate the accuracy of nine predictive equations for calculating energy expenditure in severely burned adult subjects. The selected equations have been reported as commonly used or determined to be the most accurate. This prospective, observational study was conducted on adult subjects admitted between October 2007 and July 2010 with ≥20% TBSA full-thickness burns (excluding electrical burns or severe head injury). Indirect calorimetry measurements were conducted as a convenience sample during the first 30 days after injury. Demographic data were collected, and resting energy expenditure was calculated using the nine selected predictive equations and compared to measured energy expenditure (MEE) using descriptive and comparative statistics. Data were collected on 31 subjects with an average age of 46 ± 19 years and %TBSA burn of 48 ± 21%. For all equations, slopes and intercepts were significantly different from the line of identity when compared with MEE. A calorie-dependent bias was present for all equations, in that lower calorie range was overestimated and the higher calorie range was underestimated. Only the Carlson and Milner equations had results that were not significantly different from the MEE and mean differences that were not significant in all burn size ranges. None of the equations had a strong correlation with MEE. Of the equations available, the Milner and Carlson equations are the most satisfactory in predicting resting energy expenditure in severely burned adults when indirect calorimetry is unavailable.
