dementia via video consultation (VC) also collected data regarding the diagnosis of depression via video conferencing. Methods: This was a multi-site study in which a specialist carried out a cognitive assessment via VC with the patient and their carer. A second interview was carried out face to face (FTF) by a second specialist on the same day. This VC/FTF pairing was referred to as VF. Inter-rater reliability was assessed between specialists by using overall proportional agreement (PO) and kappa (k). Data on the presence of depression were collected from each specialist. Results: One hundred fifty-five participants, referred by their general practitioner for a specialist assessment at one of four participating Memory Disorder Clinics (MDCs), were divided into two groups: VF (n 1⁄4 82) or FTF (n 1⁄4 73). Seventy-five were men. The average age was 76 years (standard deviation [SD], 9; 54 to 95). The mean Standardised Mini-Mental State Examination Score was 23.8 (SD, 4.4; 8 to 30). Overall agreement via VC (PO 1⁄4 0.793; k 1⁄4 0.37; P 1⁄4 .12) was at similar levels to agreement for FTF (PO 1⁄4 0.767; k 1⁄4 0.31, P 1⁄4 .13). Conclusions: The identification of depression in this patient group was a secondary analysis within a study designed to examine the reliability of the diagnosis of dementia in patients referred to an MDC. The results suggest that recognizing depression via VC is reliable, but further studies are required because this population is not representative of a typical population in which the suitability of VC for the diagnosis of depression would be tested.
