BACKGROUND Unplanned escalations manifest as a breakdown of hospital care attributable to clinician error through missed or delayed identification of physiological instability, ineffective treatment, or iatrogenic harm. OBJECTIVES To examine the impact of an Early Warning Score-based proactive rapid response team model on the frequency of unplanned intra-hospital escalations in care compared with a rapid response team model based on staff nurse identification of vital sign derangements. DESIGN Pre- and post Early Warning Score-guided proactive rapid response team model intervention. SETTING 237-bed community hospital in the southeastern United States. PARTICIPANTS All hospitalized adults (n = 12,148) during a pre- and post-intervention period. METHODS Logistic regressions used to examine the relationship between unplanned ICU transfers and rapid response team models (rapid response team vs. Early Warning Score-guided proactive rapid response team). RESULTS Unplanned ICU transfers were 1.4 times more likely to occur during the rapid response team baseline period (OR = 1.392, 95% CI [1.017-1.905]) compared with the Early Warning Score-guided proactive rapid response team intervention period. CONCLUSIONS This study reports a difference in the frequency of unplanned escalations using different rapid response models, with fewer unplanned ICU transfers occurring during the use of Early Warning Score-guided proactive rapid response team model while accounting for differences in admission volumes, age, gender and comorbidities. Implementation of this model has implications for patient outcomes, hospital operations and costs.
