Neurologic Outcomes of Survivors of COVID-19–Associated Acute Respiratory Distress Syndrome Requiring Intubation
Bibliographic record
Abstract
OBJECTIVES: To describe 3-6-month neurologic outcomes of survivors of COVID-19-associated acute respiratory distress syndrome, invasively ventilated in the ICU. DESIGN: A bicentric prospective study during the two first waves of the pandemic (March to May and September to December, 2020). SETTING: Two academic hospital ICUs, Paris, France. PATIENTS: Adult COVID-19-associated acute respiratory distress syndrome survivors, invasively ventilated in the ICU, were eligible for a neurologic consultation between 3 and 6 months post ICU discharge. INTERVENTIONS: Follow-up by face-to-face neurologic consultation. MEASURES AND MAIN RESULTS: The primary endpoint was favorable functional outcome defined by a modified Rankin scale score less than 2, indicating survival with no significant disability. Secondary endpoints included mild cognitive impairment (Montreal Cognitive Assessment score < 26), ICU-acquired weakness (Medical Research Council score < 48), anxiety and depression (Hospital Anxiety and Depression score > 7), and posttraumatic stress disorder (posttraumatic stress disorder checklist for Diagnostic and Statistical Manual of Mental Disorders 5 score > 30). Of 54 eligible survivors, four non-French-speaking patients were excluded, eight patients were lost-to-follow-up, and one died during follow-up. Forty-one patients were included. Time between ICU discharge and neurologic consultation was 3.8 months (3.6-5.9 mo). A favorable functional outcome was observed in 16 patients (39%) and mild cognitive impairment in 17 of 33 patients tested (52%). ICU-acquired weakness, depression or anxiety, and posttraumatic stress disorder were reported in six of 37 cases (16%), eight of 31 cases (26%), and two of 27 cases (7%), respectively. Twenty-nine patients (74%) required rehabilitation (motor, cognitive, or psychologic). ICU and hospital lengths of stay, tracheostomy, and corticosteroids were negatively associated with favorable outcome. By contrast, use of alpha-2 agonists during ICU stay was associated with favorable outcome. CONCLUSIONS: COVID-19-associated acute respiratory distress syndrome requiring intubation led to slight-to-severe functional disability in about 60% of survivors 4 months after ICU discharge. Cognitive impairment, muscle weakness, and psychologic symptoms were frequent. A large multicenter study is warranted to allow identification of modifiable factors for improving long-term outcome.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
