Rationale:  

There is limited knowledge about nutritional intake and energy needs during the post-intensive care unit (ICU) period and their relationship with clinical outcome.(1)

Methods: This observational multicenter study aimed to assess the feasibility of measuring energy expenditure (IC derived respiratory quotient RQ (QNR-ENERGY COSMED)and body composition (BIVA-AKERN) in critically ill adults after ICU discharge. The provision of nutritional support (PIS test) and the resulting nutrition-related outcomes were also recorded (2). Oral supplementation was used to reach the optimal nutritional intake.

Results: A total of 43 patients were  enrolled from Januray 2024 until February 2025 in a multicenter study  at the beginning of their post-ICU period. 

The mREE was 1591±10.7 at the admission and 1.856 kcal/kg/d at the discharge (p< 0.05).The median phase angle value 4.33 at the admission and 5.05 ° at the discharge (p< 0.05); R/Q1 at the admission was 0.7 and 1.086 at the discharge (p< 0.05). There was significant correlation between PIS test scores and improved R/Q (r=0.7).

Conclusion: Measurement of energy expenditure along with the assessment of body composition provides an objective tool to enhance the functional recovery in patients during the post-ICU period.
