How Accurate Are First Visit Diagnoses Using Synchronous Video Visits with Physicians?

Area of Science:

• Medical Informatics
• Diagnostic Medicine

Background:

• Telediagnosis (TD) leverages information and communications technology for healthcare delivery.
• Rapid advancements in TD necessitate comparative studies with traditional face-to-face diagnosis (FD).

Purpose of the Study:

• To compare the diagnostic accuracy of telediagnosis (TD) versus face-to-face diagnosis (FD).
• To evaluate diagnostic precision among general medicine outpatients.

Main Methods:

• Analysis of data from 97 general medicine outpatients.
• Two physicians performed both TD and FD for initial examinations.
• Diagnostic agreement was measured using kappa (κ) coefficients.

Main Results:

• A high level of diagnostic agreement was found between TD and FD (κ = 0.75).
• Agreement between final diagnoses and both TD and FD diagnoses was also high (κ = 0.81).

Conclusions:

• Telediagnosis (TD) demonstrates diagnostic accuracy equivalent to face-to-face diagnosis (FD) for adult general medicine outpatients.
• TD can be enhanced with medical assistant support and remote examination devices for quality comparable to FD.
• TD is a valuable tool for healthcare delivery in resource-limited settings or remote areas.
