P Value | Interpretation |
---|---|---|---|
Adverse events | |||
Intercept | 3.27 (2.12, 4.42) | ||
Pre-intervention trend | 0.04 (−0.06, 0.15) | 0.42 | There is a trend towards increasing event rates although this is not significant. |
Change in slope (implementation period vs. pre-intervention period) | 0.01 (−0.16, 0.18) | 0.92 | The event rate doesn’t change but given the wide confidence intervals it is difficult to be precise about whether this is a true effect. |
Immediate change in level (implementation period vs. pre-intervention period) | 0.21 (−1.55, 1.97) | 0.81 | |
Change in slope (post-intervention period vs implementation period) | −0.27 (− 0.47, − 0.07) | 0.01 | The trend significantly reduced over this period (although the overall number of events per patients day increases) |
Immediate change in level (post-intervention period vs. implementation period) | 1.98 (−0.22, 4.18) | 0.09 |
