A multi-institutional analysis of children on long-term non-invasive respiratory support and their outcomes.

ABSTRACT: OBJECTIVES:To characterize a multi-institutional cohort of children with chronic respiratory failure that use long-term, non-invasive respiratory support, perform a time-to-event analysis of transitions to transtracheal ventilation and identify factors associated with earlier transition to transtracheal ventilation. STUDY DESIGN:A retrospective cohort study of patients less than 21 years of age with diagnoses associated with chronic respiratory failure and discharged on non-invasive respiratory support was performed using data from the Pediatric Health Information System (PHIS) between 2007 and 2015. Demographic and clinical characteristics, as well as times from index discharge on non-invasive support to transtracheal ventilation were presented. A competing risk regression model was fitted to estimate factors associated with earlier transition to transtracheal ventilation. RESULTS:A total of 3802 patients were identified. Their median age at index discharge was 10.4 years (interquartile range [IQR] 4.1-14.9). Of these patients, 337 (8.9%) transitioned to transtracheal ventilation and transitioned at a median of 11.5 months (IQR 4.6-26) post-index discharge, or a median age of 9.3 years (IQR 4.2-14.5). Competing risk modeling demonstrated that patients who were older or whose discharge occurred later in the study period had lower hazards of earlier transition to transtracheal ventilation, whereas patients with anoxia/encephalopathy and quadriplegia had higher hazards of earlier transitioning. CONCLUSIONS:Most patients on long-term, non-invasive respiratory support who progress to transtracheal ventilation transition do so within a few years of support initiation. Various characteristics were associated with earlier risk of transitioning to transtracheal ventilation. This information may enhance anticipatory guidance for this population.

Project description:Objective To investigate the clinical outcomes of preterm infants who received non-invasive high-frequency oscillatory ventilation following extubation in a neonatal intensive care unit. Methods Infants born between 25 and 34 weeks of gestation with a birth weight of <1,500 g, who were admitted into the neonatal intensive care unit of Guangxi Maternal and Child Health Hospital, Nanning, Guangxi, China, requiring mechanical ventilation on admission were randomized to the non-invasive high-frequency ventilation group, nasal intermittent positive pressure ventilation group, or nasal continuous positive airway pressure group following extubation. Their respiratory and neurodevelopmental outcomes were assessed at 12 and 24 months of corrected age. Results Among 149 preterm infants who underwent randomization, 139 completed their treatment in the neonatal intensive care unit (45, 47, 47 in the non-invasive high-frequency ventilation group, nasal intermittent positive pressure ventilation group, or nasal continuous positive airway pressure group, respectively), 113 were assessed at 12-month corrected age, and 110 of 113 were assessed again at 24-month corrected age. There were no differences in the number of times bronchitis, pneumonia, wheezing episodes, and re-hospitalization rates appeared due to respiratory diseases among the three groups (P > 0.05); the pulmonary function tests at 12-month corrected age showed respiratory rate, tidal volume, inspiratory time/expiratory time, time to peak expiratory flow/expiratory time, volume at peak expiratory flow/expiratory volume, expiratory flow at 25, 50, and 75% tidal volume were all similar among infants from the 3 groups (P > 0.05). There were no differences in the rates of neurodevelopmental impairment among the three groups at 24-month corrected age (P > 0.05). Conclusion As post-extubation respiratory support in preterm infants, non-invasive high-frequency ventilation did not increase the rates of long-term respiratory morbidities and neurodevelopmental impairment compared with nasal intermittent positive pressure ventilation and nasal continuous positive airway pressure.
