Table 2. Classification of errors by detection method.
| Error Classification | Trigger tool validated errors (%) | Safety-STOP detected “wrong-side” errors (%) |
|---|---|---|
| Discrepant info (requisition clinical hx and side modifier indicate opposite anatomic sides) | 88 (22.6) | 24 (15.6) |
| Missing info (no side specified anywhere on the requisition) | 301 (77.4) | 41 (26.6) |
| Nondiscrepant info (side modifier and requisition clinical hx are not discrepant, but wrong side indicated) | 0 (0) a | 89 (57.8) |

Trigger tool design criteria necessarily precludes detection of these errors.
