Test | Post/pre events per patient-day (95% CI)* |
---|---|
All chest radiographs | 0.74 (0.71 to 0.76) |
Urgent chest radiographs | 1.03 (0.91 to 1.15) |
Stat chest radiographs | 1.18 (1.05 to 1.30) |
Routine chest radiographs | 0.33 (0.25 to 0.40) |
Chest CT scans | 1.10 (0.74 to 1.46) |
Catheter or tube insertions | 1.04 (0.93 to 1.16) |
*These ratios are calculated by taking the number of events/patient-day (eg, chest radiographs per patient day) after the quality improvement intervention and dividing it by the number of events/patient-day before the intervention for each category. This is expressed as a value with its corresponding 95% CI.
