Self-extubation in critically ill patients: from the French OUTCOMEREA Network
摘要
Self-extubation is a common complication in intubated patients in the intensive care unit (ICU) and is associated with a high rate of reintubation. This study aimed to identify predictors of reintubation following self-extubation (SE) and assess the prognosis of these patients.
MethodsData were extracted from the French ICU database, OutcomeRea™. The primary objective was to identify factors associated with reintubation within 48 h after self-extubation. Secondary objectives included evaluating the association between reintubation and mortality, ICU length of stay, and nosocomial pneumonia.
ResultsBetween November 1996 and May 2022, 12,917 patients were intubated in the ICU. Among them, 701 patients experienced SE without therapeutic limitations at the time, and 276 (39.4%) required reintubation. In adjusted analyses, the following factors were independently associated with reintubation: a higher non-neurological SOFA score on the day before SE (OR 1.16 [1.01; 1.34]; p = 0.03), duration of invasive mechanical ventilation > 7 days before SE (OR 1.79 [1.04; 3.26]; p = 0.04), enteral nutrition on the day of SE (OR 2.59 [1.75; 3.84]; p < 0.01) and the use of non-invasive ventilation (NIV) within 24 h after SE (OR 0.28 [0.16; 0.5];p < 0.01). Reintubation within 48 h after SE was independently associated with increased 28-day mortality (HR = 3.03 [1.79; 5.12]; p < 0.01) and 90-day mortality (HR = 2.86 [1.86; 4.4]; p < 0.01), a higher risk of nosocomial pneumonia (sdHR, 18.28 [7.70; 43.42]; p < 0.01), and a 13-day increase in ICU length of stay (p < 0.01).
ConclusionEnteral nutrition on the day of SE, prolonged mechanical ventilation prior to SE, higher non-neurological SOFA scores, and use of NIV after SE were independently associated with the need for reintubation. Reintubation was also associated with increased mortality, a higher risk of nosocomial pneumonia, and prolonged ICU stay.
