- Objective: The aim was to evaluate the accuracy of methods to predict energy expenditure (EE) in patients with severe traumatic brain injury (TBI). Method: To this prospective descriptive study, a small cohort of patients (n6) with isolated, severe TBI and an expected hospital stay of ≥2-3 months were included. The EE was measured at two intervals: by continuous indirect calorimetry during mechanical ventilation and by doubly labelled water from 3rd to 5th week post injury. Different equations for prediction of EE and a portable monitor, the SenseWear Armband were compared to the measured EE. Result: The majority of methods for predicting EE agreed poorly with the measured EE during indirect calorimetry period. A good agreement was found only with the three Penn-State equations, but two were biased according to Bland Altman analysis. The Penn-State equation from 1998 was the only valid predictive method, with a mean difference per day close to zero (+22 kcal), an excellent agreement (ICC 0.82) with 72% (n54/75) accurately assessed days (±10% of the measured EE) and with all patients within clinically acceptable levels, i.e. ±15% of the measured EE. During doubly labelled water period, observations were too few for any conclusive statement. Conclusion: These data support use of the Penn-State equation from 1998 to estimate EE in patients with severe TBI while on mechanical ventilation.
