Table 3.
Relationship between quartiles of nonactionable alarm exposure in the preceding 120 minutes and response time, adjusted for all variables in Table 2.
| Variable | Adjusted median response time (95% CI), minutes | P valuea |
|---|---|---|
| Quartile 1: 0–17 alarms | 8.3 (3.8–12.8) | |
| Quartile 2: 18–31 alarms | 12.3 (6.5–18.2) | .13 (vs Quartile 1) |
| Quartile 3: 32–52 alarms | 12.3 (3.9–20.6) | .85 (vs Quartile 1) |
| Quartile 4: 53+ alarms | 10.1 (5.5–14.7) | >.99 (vs Quartile 1) |
Abbreviation: CI, confidence interval.

Adjusted for 3 comparisons using Bonferroni’s method.
Note: Model required restricting the dataset to alarms occurring after the first 120 minutes of video recording to accurately assess alarm exposure counts.
