Abstrakt: Background & Aims: Lean body mass loss due to critical illness in childhood could be detrimental to long term outcomes, including functional status and quality of life. We describe the feasibility of body composition assessment by bioimpedance spectroscopy (BIS) in the pediatric intensive care unit (PICU), and functional status and quality of life assessments up to 6 months following admission in a cohort of mechanically ventilated, critically ill children.
Methods: We conducted a prospective, observational pilot study in a multidisciplinary PICU. Children aged 1 month to 18 years who required mechanical ventilation, with expected stay in the PICU of at least 5 days were included. We examined the feasibility of consenting, enrolling, and completing baseline and 6-month assessments of BIS variables, Functional Status Scale (FSS), and Pediatric Quality of Life (Peds QL), in eligible patients.
Results: Of 32 patients approached, 23 (72%) completed baseline assessments [median (IQR) age 3.4 (1.0, 7.8) years, 14 (61%) male]; 6-month assessments were completed in 15 (65%) enrolled patients. Mean (SD) phase angle at study enrollment was 2.95 (0.93) and the impedance ratio was 0.90 (0.03). Phase angle (r s  = -0.58, p = 0.03) and impedance ratio (r s  = 0.61, p = 0.02) by BIS were significantly correlated with total FSS at PICU discharge. Median total FSS and FSS tech (feeding and respiratory domains of FSS) scores improved from enrollment [16 (13, 26) and 8 (7, 10)] to 6 months [6 (6, 9) and 2 (2, 4), respectively, p < 0.001]. Median Peds QL total, physical summary and psychosocial summary scores were not significantly different between PICU discharge and 6 months after PICU admission. Correlations between the total 6-month FSS and a) phase angle (-0.45, p = 0.197) and b) impedance ratio (0.56, p = 0.096) at PICU discharge were not significant.
Conclusions: We have demonstrated the feasibility of obtaining bedside BIS measurements in the PICU, and functional and quality of life assessments remotely following PICU discharge. Body composition and long-term assessment of functional outcomes and quality of life must be incorporated in nutrition trials in critically ill children.
