Objectives. A 6-month pilot teleconsultative project linking Georgetow
n University Medical Center (GUMC) in Washington, DC, and City Hospita
l in Martinsburg, West Virginia, 90 miles away, was designed to assess
the effectiveness of telemedicine on the clinical decision-making pro
cess for patients with urolithiasis. Methods, The telemedicine system
designed and tested for this project was based on a PC-based platform.
Videoconferencing and review of the patient's imaging studies were pe
rformed over an Integrated Service Digital Network (ISDN) with 3 Basic
Rate (BRI) ISDN lines providing a 336-kilobytes/s bandwidth through a
n Inverse Multiplexor (IMUX). Treatment options were recorded for the
clinical trial group and a simulated study group by the consulting uro
logist after the initial telephone consultation, after the telemedicin
e consultation, and after examination of those patients transferred to
GUMC. Results, A total of 32 telemedicine consultations were performe
d: 14 in the clinical trial group and 18 in the simulated study group.
The recommendation of the consulting urologist at the tertiary center
was altered in 12 patients (37.5%) after the telemedicine consultatio
n compared with the recommended treatment after the initial telephone
consultation. Conclusions. In the evaluation of patients with urolithi
asis, this telemedicine application enhanced the clinical decision-mak
ing process by allowing for improved quality of care through immediate
access and effective transfer of information between the referring ur
ologist, the patient, and the stone center specialist. (C) 1998, Elsev
