Why is body composition analysis valuable in critical care settings?

Body composition is important for understanding changes in body fat distribution, fluid balance, and loss of muscle mass, helping to maximize patient recovery and long-term outcomes.   


In addition, body composition analysis helps to differentiate between muscle, fat, and body water levels in critically ill patients. By tracking these changes, healthcare providers can guide patient care and tailor treatment plans accordingly.   


In less than 70 seconds, healthcare providers receive an InBody Result Sheet (body composition printout) that can aid in:  

Empowered by objective data, healthcare providers can more effectively evaluate patients pre- and post-operatively, improving treatment plans and long-term outcomes.


Evaluate muscle wasting and determine possible post-surgery complications

Muscle-fat analysis, which includes measurements of skeletal muscle mass (SMM), can be useful in determining patient outcomes. SMM can be crucial in determining postoperative outcomes as shown by Shibasaki, et al., 2022. They used SMM to determine the skeletal muscle mass index (SMI) by dividing it by the height squared and showed that patients diagnosed with sarcopenia preoperatively had longer hospital stays, intubation time, and time in the ICU.   


Assess hydration status and monitor fluid imbalances

Body fluid measures of extracellular water (ECW), and total body water (TBW) can aid healthcare providers in monitoring fluid imbalances and guide fluid therapy in postoperative, critically ill patients, as highlighted by Chung, et al., 2021. In a study by Hulsebos, et al., 2021, parameters of ECW and TBW were used to monitor fluid shifts in hospitalized burn patients, which resulted in correlations to the severity of injury being shown in this population.  


Gain insights into patient frailty and treatment status.

Phase angle (PhA) measured value is an indication of cell health. PhA measures can aid healthcare providers in assessing risks of adverse outcomes in critically ill COVID-19 patients, as shown by Moonen, et al., 2021, whose study observed patients during the first 24 hours of hospitalization, with a follow-up after 90 days. Additionally, Ko, et al., 2021 investigated PhA as a measure of frailty in critical illnesses, finding that high measures of PhA were associated with decreased in-hospital mortality and length of ICU care, compared to patients with low PhA. 

 In pediatric critical care settings body composition measurements are also important, as shown by Xiong, et al., 2022. They found that PhA was an independent predictor of 90-day mortality among critically ill children in the pediatric intensive care unit (PICU) as young as 1.1 years old. A low PhA was also found to be associated with a longer duration of medical ventilation. 

Additionally, these parameters can aid healthcare providers in monitoring response to rehabilitation interventions and nutritional support in ICU patients on mechanical ventilation as shown by (Viana, et al., 2021).  Even when improvements in muscle loss were not seen with the intervention, improvements in PhA, amino acid metabolism, and global health were observed, as well as reduced net protein breakdown.
