Trends in Time to Extubation for Pediatric Postoperative Cardiac Patients and Its Correlation With Changes in Clinical Outcomes: A Virtual PICU Database Study

Abstract

Objectives: Mechanical ventilation is often used in children after cardiac surgery but can impair hemodynamics and cause lung injury. Early extubation may improve ICU length of stay and survival. We aimed to describe trends in early extubation rates and evaluate if centers that more commonly practice early extubation have better severity-adjusted outcomes.

Design: Retrospective analysis was performed of admissions in the Virtual Pediatric Systems (VPS, LLC) database from 2009 to 2018. Early extubation was defined as patients extubated in the operating room or within 6 hours of PICU admission.

Setting: PICUs participating in the VPS database.

Patients: Children in the VPS database who underwent cardiac surgery.

Interventions: None.

Measurement and main results: Among 69,739 subjects, 20% were neonates, 47% underwent early extubation, 5.3% failed extubation, and 2.5% died. Overall, early extubation rates did not change over the study period. Centers were placed in one of four groups based on their early extubation rate in lower complexity surgeries. Centers that most commonly used early extubation had more ICU-free time among all patients in univariable analysis (lowest early extubation group, 23.8 d [interquartile range, 18.2-25.9 d]; highest early extubation group, 24.7 d [20.0-26.2 d]; p < 0.001). After adjusting for center volume, sex, age, surgical complexity, and preoperative ICU admission, increasing center-level early extubation rates were not associated with more ICU-free days. Higher center-level early extubation rate was not associated with mortality in univariable or multivariable analysis but was associated with decreased extubation failure rate (lowest early extubation group, 6.4%; highest early extubation group, 3.6%; p < 0.001).

Conclusions: In this large, multicenter database study, early extubation rates in postoperative cardiac patients did not significantly change between 2009 and 2018. Centers that performed early extubation more frequently did not have shorter ICU stays or difference in mortality rates but did have lower reintubation rates.
