Low-bandwidth telemedicine for pre- and postoperative evaluation in mobile surgical services.
Low-bandwidth telemedicine was used for the pre- and postoperative evaluation of patients treated by a mobile surgery service in remote Ecuador. Realtime and store-and-forward telemedicine was employed, using PCs connected via the ordinary telephone network. Between February 2002 and July 2003, 144 patients were studied preoperatively and 50 postoperatively. It was possible to establish 20 satisfactory preoperative realtime connections, which allowed good-quality, simultaneous audiovisual transmission. Thus, there were 124 preoperative assessments done by store-and-forward telemedicine and 50 postoperative assessments. Diagnoses and management plans made by a surgeon using telemedicine were compared with those made independently by a second surgeon, who saw the patient face to face. Due to poor quality of the transmitted images, 43 patients were excluded from the preoperative study and 13 from the postoperative study. In the 101 preoperative evaluations, there was agreement in 78 cases (77%); in the 37 postoperative evaluations, there was agreement in 36 cases (97%). Telemedicine may reduce the time required on site for preoperative planning, and may provide reliable postoperative surveillance, thus improving the efficiency of mobile surgery services.
