OC14 Outcomes for children receiving noninvasive ventilation as the first-line mode of mechanical ventilation at intensive care admission on vinnitsa region children hospital: a propensity score-matched cohort study

Abstract

Objectives To compare outcomes of children receiving noninvasive ventilation with those receiving invasive ventilation as first-line mode of mechanical ventilation following unplanned intensive care admission. Design Propensity score-matched cohort study analyzing data prospectively collected by the Pediatric Intensive Care Vinnitsa Regional Children Hospital 15 years (2003–2018). Setting PICU in the Vinnitsa Regional Children Hospital of whom submitted Pediatric Critical Care Minimum Dataset data for the entire study period. Patients Children consecutively admitted to study PICUs. Planned admissions following surgery, unplanned admissions from other hospitals, those on chronic ventilation, and those who did not receive mechanical ventilation on the day of PICU admission were excluded. Interventions Use of noninvasive ventilation, rather than invasive ventilation, as the first-line mode of mechanical ventilation. Measurements and Main Results PICU mortality, length of ventilation, length of PICU stay, and ventilator-free days at day 28. During the study period, there were 11,112 PICU admissions. A total of 1,114 admissions (10, 1%) were eligible for analysis once predefined exclusion criteria were applied: 504 (45.24%) received ‘noninvasive ventilation first,’ whereas 221 (19.83%) received ‘invasive ventilation first’; 24 (2.15%) admissions could not be classified. Admitting PICU site explained 6.5% of the variation in first-line mechanical ventilation group (95% CI, 4.0–18.0%). In propensity score-matched analyses, receiving noninvasive ventilation first was associated with a significant reduction in mortality by 4.2% (95% CI, 1.9–5.6%), length of ventilation by 1.8 days (95% CI, 1.0–3.3), and length of PICU stay by 2.4 days (95% CI, 1.6–3.7), as well as an increase in ventilator-free days at day 28 by 4.1 days (95% CI, 3.1–5.4). Conclusions Use of noninvasive ventilation as first-line mode of mechanical ventilation in critically ill children admitted to PICU in an unplanned fashion may be associated with significant clinical benefits.
