RESUMO
OBJECTIVE: To investigate the potential role of a store-and-forward (SAF) telemedicine system in specialty consultations initiated by primary care physicians. MATERIALS AND METHODS: In this pilot telemedicine study, patients needing consultations in cardiology, dermatology, endocrinology, and orthopedics had both standard face-to-face (FTF) consultations and SAF consultations. RESULTS: Fifteen patients had both FTF and SAF consultations, 4 had echocardiograms transmitted for an SAF consultation only, and 1 had an SAF consultation but no FTF appointment. Of 19 diagnoses made, all were essentially the same in both types of consultations; 14 of 15 FTF consultations and 15 of 19 SAF consultations resulted in additional treatment recommendations. CONCLUSIONS: While it was possible to develop a desktop system for SAF consultations, the equipment was not adequately integrated. Without total digital input, including electronic patient medical records, packaging of information is laborious and impractical. Seamlessly adapting to existing clinical practice is vital. Issues such as increasing work for the physicians or office staff, gathering adequate patient information, and designing a referral process were more difficult than we had anticipated. Patient acceptance was high, but the clinical pilot had very small numbers.

A high data rate terrestrial and satellite network was implemented to transfer medical images and data. This article describes the a optimization of the workstations and switching equipment incorporated into the network. Topics discussed in this article include tuning of the network software, the configuration of the Sun Microsystems workstations, the FORE Systems asynchronous transfer mode switches, as well as the throughput results of two telemedicine experiments undertaken by Mayo's physician staff. The technical staff was successful in achieving the data throughput needed by the telemedicine software; particularly important was the proper determination of peak throughput and TCP window sizes to ensure optimum use of the resources available on the Sun Microsystems and Hewlett Packard workstations.
