Sponsor's own description

This is a prospective, non-randomized, no placebo-controlled interventional study. The study aims to assess the safety of the web-based symptom checker SMASS-Triage and its tolerability in terms of incidence of under-triaged self-assessments and the potential risk to be life-threatening or harmful. The patient's self-triage using a symptom checker will be compared with the urgency assessments conducted sequentially by three interdisciplinary panels of physicians (panel A, B and C). The risk assessments will be based on the structured reports generated by the symptom checker and the discharge summaries of the WIC/ED.
