- A new decision tree using preoperative clinical data had good performance for predicting tracheostomy need in patients undergoing decompressive craniectomy for stroke.
Why this matters
- Tracheostomy placement may shorten duration of mechanical ventilation in patients undergoing decompressive craniectomy for stroke.
- Optimal timing of the procedure is unclear.
- Overall, 28.5% of the patients needed tracheostomy.
- A decision tree using Glasgow Coma Scale, Sequential Organ Failure Assessment score, and presence of hydrocephalus (defined as any neurologic deterioration attributable to elevated intracranial pressure) had 63% sensitivity and 84% specificity for predicting tracheostomy need.
- Compared with patients undergoing tracheostomy later (>10 days after stroke), those undergoing tracheostomy early (≤10 days) had fewer ventilator days (7.3 vs 15.2 days; P<.001 and shorter hospital length of stay vs but rates ventilator-associated pneumonia mortality were similar.>
- A retrospective analysis of prospectively collected registry data for 168 adult patients who underwent decompressive craniectomy for ischemic stroke or intracerebral hemorrhage.
- Main outcome was predicted need for tracheostomy using a propensity-weighted decision tree analysis built with factors present before surgical decompression.
- Funding: Author-provided funding.
- The study was fairly small and retrospective.
- Findings may have been affected by residual confounding.
