About

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.

Full 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.

Description:

1. The patient fulfill Diaana 2. The resident physician reads the Diaana summary 3. The resident physician see the patient in consultation. He establishes his DD without having access to the complementray exams (blood tests, x-ray, ...) 4. The senior physician see the patient at the follow-up consultation. He establishes the gold-standard diagnosis highlighted by complementary exams and imagery.
