Rehabilitation in critically ill children: Findings from the Korean National Health Insurance database

Purpose Intensive care unit (ICU) survivors suffer from physical weakness and challenges returning to daily life. With the importance of rehabilitating patients in the pediatric intensive care unit being increasingly recognized, we evaluated the prevalence of physical and occupational therapy (PT/OT)-provided rehabilitation and factors affecting its use. Methods We conducted a retrospective cohort analysis of rehabilitation between 2013 and 2019 using the Korean National Health Insurance database. All patients aged 28 days to 18 years who had been admitted to 245 ICUs for more than 2 days were included. Neonatal ICUs were excluded. Results Of 13,276 patients, 2,447 (18%) received PT/OT-provided rehabilitation during their hospitalization; prevalence was lowest for patients younger than 3 years (11%). Neurologic patients were most likely to receive rehabilitation (adjusted odds ratio [aOR], 6.47; 95% confidence interval [CI], 5.11-8.20). Longer ICU stay (versus ≤ 1 week) was associated with rehabilitation (aOR for 1-2 weeks, 3.50 [95% CI, 3.04-4.03]; 2-3 weeks, 6.60 [95% CI, 5.45-8.00]; >3 weeks, 13.69 [95% CI, 11.46-16.35]). Mechanical ventilation >2 days (aOR, 0.78; 95% CI, 0.67-0.91) and hemodialysis (aOR, 0.50; 95% CI, 0.41-0.52) were negatively affecting factors. Conclusion Prevalence of rehabilitation for critically ill children was low and concentrated on patients with a prolonged ICU stay. The finding that mechanical ventilation, a risk factor for ICU-acquired weakness, was an obstacle to rehabilitation highlights the need for studies on early preventive rehabilitation based on individual patient needs.
