210 patients were examined in-person by two dermatologists (a resident and attending) and by residents using store and forward and live interactive teledermatology. Store and forward images were 10 megapixel 24 bit color JPEGs. Live interactive video was either compressed H.264 high definition 720p resolution transmitted at 2 mbps or uncompressed high definition 1080i transmitted at 1.5 gbps. Patients were examined 3 times, once by each method in special weekend clinics and the type of video alternated between clinics. Diagnostic concordance and confidence was significantly higher for in-person exams than remote methods. Store and forward and uncompressed video concordance and confidence were about the same and significantly better than compressed video. Patients and dermatologists were significantly more satisfied with in-person consultations than remote ones. Patients were evenly divided on store and forward and live interactive methods. Dermatologists had a slight preference for uncompressed video over store and forward and were uniformly dissatisfied with compressed video.
