Abstract
We investigated the level of agreement between specialists conducting a cognitive assessment via videoconference compared with a face-to-face assessment. The patient and doctor were linked via a videoconference system which was located within the same hospital. To assess inter-rater reliability, paired face-to-face assessments were also carried out. There were 42 subjects, who were aged over 50 years and who had not attended a memory disorder clinic in the previous 12 months. A battery of standardized cognitive assessments was performed by a trained clinic nurse, prior to the two assessments by separate specialists. The weighted kappa score for face-to-face inter-rater reliability was 0.53. The agreement between face-to-face and videoconferencing assessment was 0.63. The present study shows that the use of videoconferencing for cognitive assessment results in assessment outcomes similar to those from face-to-face assessment.
