The first rapid response team (RRT) in Korea was formed in March 2008 at Asan Medical Center, although it was referred to as a medical alert team at that time. In the next decade, more than 10 other RRTs have been founded [1]. Several members of RRTs formed a committee and held academic meetings, and favorable results were published regarding the impact of RRTs on cardiac arrest [1].
The Korean government decided to implement a pilot project for a rapid response system to promote patient safety starting in 2019 [2]. In May 2019, a total of 15 RRTs were selected and received modest support from health insurance reimbursements.
Lee et al. [3] published a study entitled “Effect of a rapid response system on code rates and in-hospital mortality in medical wards”. This before-and-after study showed significantly decreased code rates for operating time, but not for non-operating time. In-hospital mortality also decreased significantly. The RRTs did not consistently reduce mortality; however, a marked reduction of mortality was reported in that study. It is worth considering that there were more than 60 RRT activations per 1,000 admissions, and the RRT activation rate is generally related to the code rates.
In the near future, there will be big data about RRTs as a result of the government’s pilot project. In Korea, it is expected that reports will analyze the effects of the rapid response system on the national scale.
Screening systems, such as the national early warning score and the modified early warning score, are currently used. In recent years, artificial intelligence–based programs dealing with the health care system have been created [4]. New screening programs are expected to be introduced and verified soon.
