Abstract
Background:The utilization of a Rapid response team (RRT) has influenced patient’s clinical outcomes in the general ward. However, characteristics of RRT-screened patients admitted in the ward or transferred to the intensive care unit (ICU) is unknown. Therefore, this study aimed to evaluate these factors.Methods:We conducted a retrospective study using patient’s data in a tertiary medical center in Korea between January 2016 and December 2017. Results: Total 1,096 patients were included; 389 patients were transferred to the ICU, and 707 patients stayed in the ward. The ICU group was more likely to be admitted for medical reasons, hepatobiliary disease, and high heart rate. More interventions were performed, hospital stays were longer, and 28-day and in-hospital mortality were higher in the ICU group. Multivariate logistic regression analyses showed that the risk factors affecting ICU admission were Sequential Organ Failure Assessment (SOFA) score, and National Early Warning Score (NEWS), platelet and lactate level. Transfer to the ICU was not associated with in-hospital mortality.Conclusions: Among RRT-activated patients, those with higher SOFA, NEWS scores, and lactate levels were more likely to transfer to the ICU. Therefore, these patients should be closely monitored and considered for ICU transfer.
