|---|---|---|---|---|---|
Number of patients leaving ED without being seen by a physician (fewer) | 32 830 (4 studies) | 1 RCT 3 observational studies | 1.3 (1.2-6.8) percent | Moderately strong ⊕⊕⊕ | Upgraded because of concordance of data |
Waiting time (shorter) | 25 927 (3 studies) | No RCT 3 observational studies | 18 (16-20) min | Limited ⊕⊕ | Downgraded because of study quality and heterogeneity |
Length of stay (shorter) | 29 674 (4 studies) | 2 RCT 2 observational studies | 40.5 (0-55) min | Limited ⊕⊕ | Upgraded because of outcome size. Downgraded because of study quality. |
