Effect of Intervention on Time until Treatment Was Started and on Time until Condition Was Resolved, When Alerting Situation Did Not Satisfy the Laboratory's Critical Reporting Criteria
| Median (Interquartile Range) | Mean (SD) | Range | |
|---|---|---|---|
| Time until treatment was ordered (in hours): | |||
| All cases not meeting laboratory's criteria (N = 95) | 1.5 (0.4-5.3) | 5.4 (13.0) | 0-100.5 |
| Intervention cases: alert but no phone call (n = 51) | 1.2 (0.2-2.9) | 4.8 (14.8) | 0-100.5 |
| Control cases: no alert, no phone call (n = 44) | 2.5 (0.9-6.5) | 6.1 (10.7) | 0.1-66.1 |
| P value | 0.009* | 0.01† | - |
| Time until condition was resolved (in hours): | |||
| All cases not meeting laboratory's criteria (N = 90) | 9.7 (6.2-23.8) | 21.7 (30.9) | 0.7-198.5 |
