Researchers used data from the National Surgical Quality Improvement Program to identify risk factors for an intubation scoring system: patient age, physical status as defined by the American Society of Anesthesiologists, the presence of preoperative sepsis, and total operative time.
The researchers’ Unplanned Intubation Risk Index ranged from 0 (lowest risk) to 18 (highest risk). When compared with NSQIP data for more than 176,000 patients from 2008, the scoring system had a 79 percent accuracy rate in determining which patients would require unplanned intubation.
