Results of various phases of the study
| Phases of the study | Subjects (n) | Median (IQR) s | P value* | Comments |
| Preintervention phase | 15 | 300 (210) | – | Wide distribution of IQR suggesting the high variability of performance among the ED staff |
| Intervention phase after PDSA 1 | 14 | 165 (125) | 0.293 | Simulation-based teaching for residents and nursing officers |
| Intervention phase after PDSA 2 & 3 | 10 | 157 (66) | 0.075 | On-site training was lasting 10–15 min were organised as part of PDSA 2. Based on the inputs during the training, airway drug checklist and bougie were introduced in the resuscitation trolley the next day (PDSA 3). Analysis of both the PDSAs has been done together |
| Postintervention phase | 21 | 126 (42) | 0.003 | The decrease in median intubation time and IQR shows the improvement in system and standardisation of procedure in the ED |
*Data were compared with the baseline phase values using the Mann-Whitney U test.
