A Multifaceted Extubation Protocol to Reduce Reintubation Rates in the Surgical ICU

Reintubation is associated with significant morbidity and mortality. The reintubation rate in surgical ICUs (SICUs) is ∼10% nationally but was 17.0% in our SICU. The objective of this study was to determine if the reintubation rate could be reduced with a protocol for extubation assessment and post-extubation care consisting of standardized extubation criteria and targeted interventions for patients at high risk for reintubation.Standardized extubation criteria for all SICU patients were identified via literature review and best-practice guidelines. High reintubation risk criteria were identified (age ≥ 65 years, chronic cardiopulmonary disease, ≥ 4 days intubated, emergency intubation, and fluid balance ≥ 5 liters) through a literature review and 13-month retrospective review of reintubations in our institution's SICU. Patients meeting at least one criterion putting them at higher risk for reintubation received interventions including post-extubation high-flow nasal cannula for 24 hours and algorithm-guided respiratory therapy.During the 12-month period following protocol implementation, 36 of 402 extubations resulted in reintubations (9.0% vs. 17.0% preintervention, p < 0.001). Among all extubations, 305 (75.9%) were identified as high risk. Among reintubated patients, 34 (94.4%) met high-risk criteria. The mortality rate for reintubated patients was 40.0%, compared to 3.3% in those not reintubated (p < 0.001). The high-risk screening tool had a negative predictive value of 98%.A multifaceted and pragmatic extubation and post-extubation care protocol significantly reduced one SICU's reintubation rate. This protocol can be easily implemented in any SICU to improve patient outcomes following extubation.
