简要总结
Single-center, unblinded, 1:1 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 differential diagnosis of the senior physician.
详细描述
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, 1:1 parallel pseudo-randomized efficacy trial will be performed. No follow-up is necessary, because patients are seen once and all data are collected on this time. The study will take place in the emergency outpatient unit of Geneva University Hospital and include patients suffering from symptoms covered by Diaana.
Patients in the intervention group will fullfil Dianna. Then, the resident physician will read Diaana summary, perform his consultation, and fullfil case report form, including his differential diagnosis. Then, the senior physician will see the patient and establish the gold-standard differential diagnosis. In the control group, the residents will directely establish a differential diagnosis, without the help of Diaana.

结局指标
主要结局
Differential diagnosis established by the resident physician
时间窗: At day 0
The resident physician will select up to 5 diagnose in an exhaustive list. The senior physician will do the same in order to establish the gold-standard differential diagnosis. The accuracy of the resident's differential diagnosis will be measured as the percentage of correct diagnose selected by the resident compared to the gold standard.
次要结局
- Patient satisfaction(At day 0)
- Consultation time(At day 0)
- Differential diagnosis estabished by Diaana(At day 0)
