Rationale: Accurate nutritional management in a rehabilitation ward for critically injured young adults is challenging due to significant metabolic variability. Guidelines predicting caloric and protein needs often inadequately capture individual requirements, potentially affecting recovery outcomes, particularly in patients undergoing rehabilitation and amputations

Methods: We conducted a retrospective observational analysis in a rehabilitation ward involving 30 critically injured young adults (mean age 25.97 ± 8.21 years; average BMI prior to injury 24.65 ± 2.91 kg/m²; 23.3% with amputations). Indirect calorimetry (IC) measured resting metabolic rates (RMR), which were compared to guideline-predicted and actual intake of calories and protein per kilogram of body weight. Biochemical and demographic data were also evaluated

Results: Measured RMR values demonstrated substantial variability among patients (mean 30.28 ± 6.51 kcal/kg/day) compared to guideline predictions (mean 27.69 ± 0.93 kcal/kg/day, p=0.051) and actual caloric intake (mean 28.86 ± 9.00 kcal/kg/day, p=0.508). Similarly, considerable variation was noted between expected (mean 1.50 ± 0.003 g/kg/day) and actual protein intake (mean 1.49 ± 0.56 g/kg/day, p=0.606).

Conclusion: Our findings highlight considerable metabolic variability among critically injured young adults in rehabilitation, emphasizing that standard formulas lack precision for this unique patient population. Combining dietetic intake assessments with indirect calorimetry is essential for accurately tailoring individualized nutritional plans, thus enhancing rehabilitation outcomes.
