These are peer-reviewed supplementary materials for the article 'Continuous vital sign monitoring in patients after elective abdominal surgery: a retrospective study on clinical outcomes and costs' published in the Journal of Comparative Effectiveness Research.

Table S1: Clinical outcomes in different disease categories
Table S2: Linear regression results for length of stay
Table S3: Logistic regression summary results for ICU admission
Table S4: EWS measurements
Table S5: EWS scores of HR and RR measurements
Table S6: Linear regression summary results for ward costs
Table S7: Linear regression summary results for ICU costs
Table S8: Linear regression summary results for total costs

Aim: To assess changes in outcomes and costs upon implementation of continuous vital sign monitoring in postsurgical patients. Materials & methods: Retrospective analysis of clinical outcomes and in-hospital costs compared with a control period. Results: During the intervention period patients were less frequently admitted to the intensive care unit (ICU) (p = 0.004), had shorter length of stay (p < 0.001) and lower costs (p < 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). Conclusion: Continuous vital sign monitoring may have contributed to fewer ICU admissions and lower ICU costs in postsurgical patients.
