<b>These are peer-reviewed supplementary materials for the article '</b><b>Continuous vital sign monitoring in </b><b>patients after elective abdominal surgery: </b><b>a retrospective study on clinical outcomes </b><b>and costs</b><b>' published in the</b><b> </b><b><i>Journal of Comparative Effectiveness Research</i></b><b>.</b><b>Table S1: </b>Clinical outcomes in different disease categories<b>Table S2:</b> Linear regression results for length of stay<b>Table S3:</b> Logistic regression summary results for ICU admission<b>Table S4:</b> EWS measurements<b>Table S5: </b>EWS scores of HR and RR measurements<b>Table S6:</b> Linear regression summary results for ward costs<b>Table S7:</b> Linear regression summary results for ICU costs<b>Table S8:</b> Linear regression summary results for total costs<b>Aim:</b> To assess changes in outcomes and costs upon implementation of continuous vital sign monitoring in postsurgical patients. <b>Materials &amp; methods:</b> Retrospective analysis of clinical outcomes and in-hospital costs compared with a control period. <b>Results:</b> During the intervention period patients were less frequently admitted to the intensive care unit (ICU) (p = 0.004), had shorter length of stay (p &lt; 0.001) and lower costs (p &lt; 0.001). The intervention was associated with a lower odds of ICU admission (odds ratio: 0.422; p = 0.007) and ICU related costs (coefficient: -622.6; p = 0.083). <b>Conclusion:</b> Continuous vital sign monitoring may have contributed to fewer ICU admissions and lower ICU costs in postsurgical patients.
