Clinical Trial Summary

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.

Intervention

Device:
• SMASS-Triage
SMASS-Triage is a web-based symptom checker developed by In4medicine Ltd. SMASS-Triage is based on a computerized transparent neural network, which was trained with the evidence of more than 1200 studies and the expertise of various panels of specialists in the field of preclinical medical triage. SMASS-Triage provides digitalized questionnaires of 87 frequent reasons of encounters (e.g. fever, cough, abdominal pain) and their associated red flags. The triage-result of SMASS-Triage encompasses the appropriate time-to-treat (T2T) and the adequate point-of-care (PoC).
