Study ObjectivesCongenital central hypoventilation syndrome (CCHS) is a rare disease predisposing children to respiratory failure due to abnormal ventilatory drive. Variability in hypoventilation and respiratory support need have been reported. We aim to identify clinical variables associated with incident tracheostomy and common etiologies of hospitalization among children with CCHS.MethodsHospital discharge records were obtained for children (<21 years) with CCHS hospitalized between 2006 and 2019 from the Kid's Inpatient Database. Primary diagnostic categories for hospitalizations with CCHS were summarized. Multivariable logistic regression models were used to explore risk factors associated with incident tracheostomy.ResultsAmong 2404 hospitalizations with CCHS, 133 (5.5%) had incident tracheostomy, 1230 (51.2%) had established tracheostomy, and 1041 (43.3%) had no tracheostomy. Compared with children without tracheostomy, those with incident tracheostomy were younger, had a history of prematurity, congenital heart disease, laryngeal, glottic, and subglottic stenosis (LGSS), congenital airway anomalies, neuromuscular weakness, gastroesophageal reflux disease. Children without tracheostomy had higher mortality than those with tracheostomy status (2.19% vs. 0.66%). Multivariable‐adjusted analyses showed that incident tracheostomy was associated with infancy (0–1 years), neuromuscular weakness, and congenital heart disease. Most common diagnostic categories include (1) diseases of the respiratory system (30.23%), (2) injury and poisoning (9.35%), and (3) diseases of the nervous system and sense organs (6.71%).ConclusionsChildren with CCHS who received incident tracheostomy are more likely to be younger and with LGSS, neuromuscular weakness and congenital heart disease. Clinicians should be aware of these risk factors representing more severe CCHS with earlier manifestation needing tracheostomy. Higher mortality among nontracheostomy group highlights the need for considering tracheostomy in caring for children with CCHS.
