A rapid response team is associated with reduced overall hospital mortality in a Chinese tertiary hospital: a 9-year cohort study.

ABSTRACT: Background:Although the evidence for its effectiveness remains uncertainty, rapid response systems are implemented across many hospitals across the world. Increasingly, hospitals in China have recently started to adopt a medical emergency or rapid response team (RRT). Hence, we aimed to determine whether the implementation of an RRT in Chinese hospitals also improved outcomes. Methods:Our hospital is a Joint Commission International (JCI) accredited, tertiary teaching hospital with 1,200 beds. We conducted a retrospective cohort study comparing 60 months after the implementation of the RRT (January 1, 2013, to December 31, 2017) and 36 months before implementation (January 1, 2009, to December 31, 2011). The outcomes included the overall hospital mortality and incidence of codes. Results:We analyzed 144,673 non-obstetric hospital admissions and 1,269,621 patient days in the control period and 348,687 non-obstetric hospital admissions and 2,361,913 patient days after the RRT implementation. The RRT was activated 834 times (2.39 calls per 1,000 patients and 0.35 call per 1,000 patient-days). There was no difference in the code rate (0.23 vs. 0.17 per 1,000 patient days, P=0.379) between the two periods. Although the hospital mortality had remained stable around 3.0 per 1,000 patients from 2009 to 2011, there was a significant 40% decrease of overall hospital mortality from 2.95 to 1.77 per 1,000 non-obstetric patients after the implementation of RRT (P=0.001), and the annual mortality showed a consistent decrease (P=0.037 for the trend). Moreover, the increase of RRT activations was significantly correlated with the decrease of hospital mortality (P=0.025). Conclusions:RRT implementation was associated with reduced overall hospital mortality in a Chinese tertiary hospital.
