| Summary: | Virtual patients (VP) have been advocated as reliable tools for teaching and evaluating clinical skills and competence. We have developed an internet-based, OSCE-like, conversational VP system designed both for training and assessment of medical students. The system, that encompasses complete patient management from H&P to diagnostic procedures and treatment, has now been used regularly during the clerkship of internal medicine. The present article describes the system and compares assessments undertaken with the VP-system over the last five years, to traditional bed-side oral exams. All students practiced on their own exercise VP cases, while preparing for the final exam. A total of 586 students were evaluated simultaneously with both assessment modalities. The αCronbach of the VP exam averaged 0.86. No correlation was found between the grades obtained in the two exams, indicating that the VP exam evaluated different parameters than those assessed by the examiners in the oral examinations. We conclude that a VP system can be utilized as a valid and reliable examination tool. It is also most useful for independent training by students during their ward-based learning, as well as when not studying in classes, wards or clinics, when social distancing is required.
