Influence of the severity grade of the interventions, the use of a printed memory tool and the timing of patient draping on the number of items* orally confirmed and validated during the Time Out period†
| Grade of the interventions | Use of the printed checklist as a memory tool | Timing | |

*In the Geneva University Hospitals, the Time Out has seven items.
†Between columns, the totals are not always equal to 79, due to missing data.
NS, non-significant.
