One-Year Outcomes in Patients With Acute Stroke Requiring Mechanical Ventilation.

BACKGROUND: Long-term outcomes of patients with severe stroke remain poorly documented. We aimed to characterize one-year outcomes of patients with stroke requiring mechanical ventilation in the intensive care unit (ICU). METHODS: We conducted a prospective multicenter cohort study in 33 ICUs in France (2017-2019) on patients with consecutive strokes requiring mechanical ventilation for at least 24 hours. Outcomes were collected via telephone interviews by an independent research assistant. The primary end point was poor functional outcome, defined by a modified Rankin Scale score of 4 to 6 at 1 year. Multivariable mixed models investigated variables associated with the primary end point. Secondary end points included quality of life, activities of daily living, and anxiety and depression in 1-year survivors. RESULTS: Among the 364 patients included, 244 patients (66.5% [95% CI, 61.7%-71.3%]) had a poor functional outcome, including 190 deaths (52.2%). After adjustment for non-neurological organ failure, age ≥70 years (odds ratio [OR], 2.38 [95% CI, 1.26-4.49]), Charlson comorbidity index ≥2 (OR, 2.01 [95% CI, 1.16-3.49]), a score on the Glasgow Coma Scale <8 at ICU admission (OR, 3.43 [95% CI, 1.98-5.96]), stroke subtype (intracerebral hemorrhage: OR, 2.44 [95% CI, 1.29-4.63] versus ischemic stroke: OR, 2.06 [95% CI, 1.06-4.00] versus subarachnoid hemorrhage: reference) remained independently associated with poor functional outcome. In contrast, a time between stroke diagnosis and initiation of mechanical ventilation >1 day was protective (OR, 0.56 [95% CI, 0.33-0.94]). A sensitivity analysis conducted after exclusion of patients with early decisions of withholding/withdrawal of care yielded similar results. We observed persistent physical and psychological problems at 1 year in >50% of survivors. CONCLUSIONS: In patients with severe stroke requiring mechanical ventilation, several ICU admission variables may inform caregivers, patients, and their families on post-ICU trajectories and functional outcomes. The burden of persistent sequelae at 1 year reinforces the need for a personalized, multi-disciplinary, prolonged follow-up of these patients after ICU discharge. REGISTRATION: URL: https://www.

Prospective multi-center evaluation of the incidence of unplanned extubation and its outcomes in French intensive care units. The Safe-ICU study.

BACKGROUND: We aimed to determine the epidemiology and outcomes of unplanned extubation (UE), both accidental and self-extubation, in ICU. METHODS: A multicentre prospective cohort study was conducted in 47 French ICUs. The number of mechanical ventilation (MV) days, and planned and unplanned extubation were recorded in each center over a minimum period of three consecutive months to evaluate UE incidence. Patient characteristics, UE environmental factors, and outcomes were compared based on the UE mechanism (accidental or self-extubation). Self-extubation outcomes were compared with planned extubation using a propensity-matched population. Finally, risk factors for extubation failure (re-intubation before day 7) were determined following self-extubation. RESULTS: During the 12-month inclusion period, we found a pooled UE incidence of 1.0 per 100 MV days. UE accounted for 9% of all endotracheal removals. Of the 605 UE, 88% were self-extubation and 12% were accidental-extubations. The latter had a worse prognosis than self-extubation (34%vs. 8% ICU-mortality, p < 0.001). Self-extubation did not increase mortality compared with planned extubation (8 vs. 11%, p = 0.075). Regardless of the type of extubation, planned or unplanned, extubation failure was independently associated with a poor outcome. Cancer, higher respiratory rate, lower PaO2/FiO2 at the time of extubation, weaning process not-ongoing, and immediate post-extubation respiratory failure were independent predictors of failed self-extubation. CONCLUSION: Unplanned extubation, mostly represented by self-extubation, is common in ICU and accounts for 9% of all endotracheal extubations. While accidental extubations are a serious and infrequent adverse event, self-extubation does not increase mortality compared to planned extubation.
