      abstract = {<p>Importance: Risk scores used in early warning systems  exist for general inpatients and patients with suspected  infection outside the intensive care unit (ICU), but their  relative performance is incompletely characterized.  </p><p>Objective: To compare the performance of tools used  to determine points-based risk scores among all  hospitalized patients, including those with and without  suspected infection, for identifying those at risk for  death and/or ICU transfer.</p><p>Design, Setting, and  Participants: In a cohort design, a retrospective analysis  of prospectively collected data was conducted in 21  California and 7 Illinois hospitals between 2006 and 2018  among adult inpatients outside the ICU using points-based  scores from 5 commonly used tools: National Early Warning  Score (NEWS), Modified Early Warning Score (MEWS), Between  the Flags (BTF), Quick Sequential Sepsis-Related Organ  Failure Assessment (qSOFA), and Systemic Inflammatory  Response Syndrome (SIRS). Data analysis was conducted from  February 2019 to January 2020.</p><p>Main Outcomes and  Measures: Risk model discrimination was assessed in each  state for predicting in-hospital mortality and the combined  outcome of ICU transfer or mortality with area under the  receiver operating characteristic curves (AUCs). Stratified  analyses were also conducted based on suspected  infection.</p><p>Results: The study included 773477  hospitalized patients in California (mean [SD] age, 65.1  [17.6] years; 416 605 women [53.9%]) and 713786  hospitalized patients in Illinois (mean [SD] age, 61.3  [19.9] years; 384 830 women [53.9%]). The NEWS exhibited  the highest discrimination for mortality (AUC, 0.87; 95%  CI, 0.87-0.87 in California vs AUC, 0.86; 95% CI, 0.85-0.86  in Illinois), followed by the MEWS (AUC, 0.83; 95% CI,  0.83-0.84 in California vs AUC, 0.84; 95% CI, 0.84-0.85 in  Illinois), qSOFA (AUC, 0.78; 95% CI, 0.78-0.79 in  California vs AUC, 0.78; 95% CI, 0.77-0.78 in Illinois),  SIRS (AUC, 0.76; 95% CI, 0.76-0.76 in California vs AUC,  0.76; 95% CI, 0.75-0.76 in Illinois), and BTF (AUC, 0.73;  95% CI, 0.73-0.73 in California vs AUC, 0.74; 95% CI,  0.73-0.74 in Illinois). At specific decision thresholds,  the NEWS outperformed the SIRS and qSOFA at all 28  hospitals either by reducing the percentage of at-risk  patients who need to be screened by 5% to 20% or increasing  the percentage of adverse outcomes identified by 3% to  25%.</p><p>Conclusions and Relevance: In all hospitalized  patients evaluated in this study, including those meeting  criteria for suspected infection, the NEWS appeared to  display the highest discrimination. Our results suggest  that, among commonly used points-based scoring systems,  determining the NEWS for inpatient risk stratification  could identify patients with and without infection at high  risk of mortality.</p>},
