Spillover of Early Extubation Practices From the Pediatric Heart Network Collaborative Learning Study

Area of Science:

• Pediatric Cardiac Surgery
• Clinical Practice Implementation
• Quality Improvement in Healthcare

Background:

• The Pediatric Heart Network Collaborative Learning Study implemented a clinical practice guideline to enhance early extubation after infant cardiac surgeries.
• This study investigated whether the guideline's success in improving extubation for specific procedures (tetralogy of Fallot, coarctation of the aorta) extended to other infant cardiac surgeries.

Purpose of the Study:

• To assess the impact of collaborative learning strategies on early extubation rates in infants undergoing cardiac surgeries not initially targeted by the clinical practice guideline.
• To determine if improvements in extubation practices demonstrated a 'spillover' effect to other patient populations.

Main Methods:

• Observational analysis of data from four hospitals participating in the Pediatric Heart Network Collaborative Learning Study.
• Comparison of aggregate early extubation rates and time to extubation between the 12 months pre-guideline and 12 months post-guideline implementation periods.
• Analysis stratified by surgical complexity (lower vs. higher) and specific procedures (ventricular septal defect repair, atrioventricular septal defect repair, superior cavopulmonary anastomosis, arterial switch operation, isolated aortopulmonary shunt).

Main Results:

• Early extubation rates significantly increased for lower-complexity surgeries (30.2% vs. 18.8%, p=0.006) post-guideline, with reduced time to extubation.
• Ventricular septal defect repair showed a significant increase in early extubation (47% vs. 26%, p=0.006), but outcomes varied by surgery type and hospital.
• No significant changes in early extubation rates or time to extubation were observed for higher-complexity surgeries.

Conclusions:

• The clinical practice guideline demonstrated a sustainable spillover effect on early extubation for lower-complexity infant cardiac surgeries one year after study completion.
• The observed variation in outcomes across different surgical procedures and study sites suggests that center-specific factors influence the adoption and effectiveness of clinical practice guidelines.
• Postoperative extubation outcomes for higher-complexity surgeries were not impacted by the implemented guideline.
