Table 2. Association of Rapid Response Team Implementation on Hospital Mortality for Overall Cohort of 56 Hospitals.

Estimated derived from hierarchical log-binomial regression model of mortality over time. Implementation of a rapid response team was not associated with lower hospital mortality in the year after implementation (model intercept) or lower than expected mortality during the entire post-implementation period (model slope). Model slope estimates at each post-implementation year are also reported.

Year After RRT Implementation	RR for Model Slope at each Post-Implementation Year RR (95% CI)	Instantaneous Effect (Model Intercept) RR (95% CI)	Per-Year Effect (Model Slope) RR (95% CI)	Global P-value for Overall Effect
0	0.98 (0.94, 1.02)	0.98 (0.94, 1.02) p=0.30	1.01 (0.99, 1.02) p=0.30	p=0.36
1	0.98 (0.94, 1.03)
2	0.99 (0.94, 1.04)
3	1.00 (0.94, 1.06)
4	1.01 (0.94, 1.08)
5	1.01 (0.94, 1.10)
