Quality improvement to reduce chronic lung disease rates in very-low birth weight infants: High compliance with a respiratory care bundle in a small NICU

Abstract

Objective: Reduce chronic lung disease by 10% among very-low birth weight infants by implementing a consistent respiratory care bundle. Study design: Prospective quality improvement study of infants below 32 weeks gestation in a small neonatal intensive care unit. A respiratory care bundle to eliminate inter-provider variability and minimize use of mechanical ventilation was implemented. This included: defining delivery room management with use of continuous positive airway pressure/nasal intermittent positive pressure ventilation, uniform intubation/extubation criteria, and standardizing ventilation/post-extubation support. Results: A total of 107 very-low birth weight infants were included in this project. Compliance with the respiratory care bundle was >90%. Chronic lung disease rates at 36 weeks postmenstrual age fell from 43 to 12% (P = 0.0006), rates of combined chronic lung disease/death decreased from 50 to 20% (P = 0.002, OR = 0.25, 95% CI 0.1-0.6), rates of severe intraventricular hemorrhage decreased from 13 to 0% (P = 0.005), and surgical ligation of patent ductus arteriosus decreased from 35 to 3% (P < 0.0001). Conclusion: High compliance with the respiratory care bundle was achieved and a 73% reduction in chronic lung disease rates in very-low birth weight infants occurred.
