Hospitals routinely use rapid response teams (RRTs) to treat and triage unstable patients, but early and reliable identification of high-risk patients remains challenging.1 Objective, vital sign–based risk prediction scores, such as the Modified Early Warning Score (MEWS), have been developed but have limited accuracy.2 The Patient Acuity Rating (PAR), a ...
