Table 1 Derivation and validation of electronic note search algorithm

From: Retrospective derivation and validation of a search algorithm to identify extubation failure in the intensive care unit

  Search algorithm Sensitivity% (95% CI) Specificity% (95% CI)
Initial signature Airway Tube Status: Intubated/Inserted within 72 h of being extubation/extubated 85% (56%-97%) 95% (87%-98%)
Final signature Airway Tube Status: Intubated/Inserted within 72 h of being extubation/extubated 93% (64%-99%) 100% (95%-100%)
Airway Tube Type: Endotracheal tube
Validation Airway Tube Status: Intubated/Inserted within 72 h of being extubation/extubated 94% (69%-99%) 98% (92%-99%)
Airway Tube Type: Endotracheal tube
