Summary

Single-center, unblinded, 2:1 parallel pseudo-randomized efficacy trial. In the intervention group only, resident physicians will be assisted by the automated medical history-taking device "Diaana" during their consultations in outpatient ambulatory unit of the Geneva University Hospital. In both groups, the differential diagnosis of the resident physician will be compared to the gold-standard diagnosis of the senior physician.

Detailed description

Automated medical history-taking devices (AMHTD) are emerging tools with the potential to increase the quality of medical consultations by providing physicians with an exhaustive, high-quality, standardized anamnesis and differential diagnosis. In this study, the investigators aimed to establish whether an AMHTD of interest, "Diaana", allowed the physician to establish a more precise differential diagnosis. A single-center, unblinded, 2:1 parallel pseudo-randomized efficacy trial will be performed. A consultation follow-up is organized at 4-6 weeks, were the gold-standard diagnosis is established by the senior physician. The study will take place in the emergency outpatient unit of La Colline Hospital (Geneva, Switzerland) and include patients suffering from symptoms covered by Diaana. Patients in the intervention group will fulfill Dianna. Then, the resident physician will read Diaana summary, perform his consultation, and fulfill case report form, including his differential diagnosis. Then, the senior physician will see the patient and establish the gold-standard diagnosis. In the control group, the residents will directly establish a differential diagnosis, without the help of Diaana.

Interventions

Type	Name	Description
DEVICE	Diaana	Diaana, the AMHTD used, functions as follows: on the basis of an interactive questionnaire completed by the patient before the consultation, it performs an exhaustive anamnesis focused on the problem and proposes a panel of DDs with a high sensitivity. The artificial reasoning system of "Diaana" mimics how a specialist physician would reason to establish a DD. The information transmitted is in an easy-to-use form for the physician that includes a summary of the anamnesis centered on relevant elements from the questionnaire and a list of possible diagnoses with their emergency level, potential contributing factors, and first-line management proposals.
