Nordal EJ, Moseng D, Kvammen B, et al. A comparative study of teleconsultations versus face-to-face consultations. J Telemed Telecare 2001;7(5):257-265.
"We compared the diagnoses made by one dermatologist via telemedicine with those of another dermatologist made in a face-to-face consultation. The patients first underwent a teledermatology consultation and then a face-to-face consultation. A general practitioner was present with the patient in the videoconference studio. Videoconferencing equipment connected at 384 kbit/s was used. The doctor-patient relationship and the satisfaction of the patients and dermatologists in the two settings were assessed, as well as technical conditions during the videoconferences. There were 121 patients, with a mean age of 40 years (range 17-82 years). There was a high degree of concordance between the two sets of diagnoses, with 72% complete agreement and 14% partial agreement between the two dermatologists. A total of 116 patients (96% of those included) completed a questionnaire. Both the patients and the dermatologists were in general satisfied with the videoconferences. Videoconferencing with a participating general practitioner may be useful in dermatology, but the technique should be used only for selected patients."

Workflow-Related Findings
In 72 percent of the consultations there was complete concordance between then two dermatologists, in 14 percent partial concordance, and in 15 percent disagreement.
"Overall, 14% of the satisfaction ratings favoured the tele-consultations, whereas 32% favoured the face-to-face consultation. Face-to-face consultations were reported to be significantly better (27-31% of the consultations) than telemedicine (6-11%) on the items relating to contact, confidence, and the patient's understanding of the problem."
For the majority of the questions, there were no significant differences in the patient's evaluations of tele-consultation and face-to-face consultation. The only exception was for the question regarding the patient's feeling of contact with the dermatologist, where a significant proportion was more satisfied with tele-consultation than with face-to-face consultation.
The face-to-face consultations lasted a little longer than the video conferences (10.1 vs 9.5 min) and were slightly longer for women than for men.
