Effectiveness Analysis of a Part-Time Rapid Response System During Operation Versus Nonoperation*

Abstract

The implementation of a part-time rapid response system reduced the cardiopulmonary arrest incidence based on the reduction of cardiopulmonary arrest during rapid response system operating times. Further analysis of the cost effectiveness of part-time rapid response system is needed.

A rapid response system reduces the incidence of in-hospital postoperative cardiopulmonary arrest: a retrospective study

“…These findings are consistent with our previous observations in hospitalized medical (nonsurgical) patients admitted to an internal medicine ward. 10 Postoperative mortality is influenced by the patient's underlying preoperative medical status as well as surgeryand anesthesia-related factors. 15,16 It is assumed that postoperative CPA may be prevented (or delayed) by providing early interventions in response to pre-arrest alarms alerting to potential postoperative cardiovascular or respiratory compromise.…”

“…20 In our previous study involving hospitalized medical (non-surgical) patients, pre-alarm laboratory abnormalities were observed in 11% of patients experiencing CPA compared with 35.5% of the postoperative patients experiencing CPA in the present study. 10 Currently, the relative value of laboratory tests vs vital signs when assessing pre-arrest alarms remains controversial. We surmise that these laboratory test are useful indicators of impeding deterioration as they comprise components of the APACHE and sequential organ failure assessment (SOFA) scores.…”

“…Similarly, in our previous study involving hospitalized medical (non-surgical) patients, hypotension, decreased SpO 2 , and an abnormal respiratory rate were the most frequent pre-arrest alarm triggers. 10,21 In our hospital, the automatic electronic dashboard system (BESTboardÒ) is refreshed every five minutes, but for most of the postoperative patients recovered in the general ward, vital signs were obtained intermittently at four to eight-hour intervals. While it seems reasonable to assume that more frequent monitoring of vital signs would result in a greater decrease in the incidence of CPA, there is some evidence to suggest that this may not be the case.…”

“…We previously showed that the RRS established at the Seoul National University Bundang Hospital (SNUBH) was associated with a reduction in CPA in hospitalized patients. 10 The purpose of the present study was to assess whether the implementation of the RRS at our institution was associated with a reduced incidence of postoperative CPA in patients recovering in a general ward.…”

A Multicenter Validation Study of the Deep Learning-based Early Warning Score for Predicting in-hospital Cardiac Arrest in Patients Admitted to General Wards

“…A rapid response system (RRS) is a strategy for preventing cardiac arrest or deterioration by providing immediate and e cient interventions by tracking and monitoring patients' conditions [1,2]. The system is composed of four major components: the afferent limb, the efferent limb, the administrative limb and quality monitoring [3].…”
