OBJECTIVE: A second medical opinion can aid in the investigation of a health problem as well as in the definition of the therapeutic approach. The present study is aimed at demonstrating a process of second medical opinion by means of a web-based multispecialty system adapted for radiology. MATERIALS AND METHODS: The system was utilized by 49 residents at Universidade Federal de São Paulo, Brazil, who gave their medical opinion on 52 second opinion requests. Questionnaires were utilized as an evaluation tool. RESULTS: A total of 1704 medical second opinions were evaluated and 514 (29.1%) of them were defined as satisfactory. In 64.4% of cases, the answers of the questionnaires indicated that the images quality did not affect the diagnosis. On average, 6 minutes and 26 seconds was the time required to issue a remote second medical opinion. CONCLUSION: A process of second medical opinion by means of a web-based multispecialty system adapted for radiology has shown to be an excellent tool in the management of therapeutic approaches.

OBJECTIVE: To compare the time required for generation and typing of radiology reports by means of an electronic system based on the technology of voice over internet protocol (VoIP) and the traditional system, in which the report is handwritten by the radiologist. MATERIALS AND METHODS: It was necessary to model, build and deploy the proposed electronic system, capable of recording the reports in a digital audio format and comparing it with the traditional method. Radiologists and transcriptionists recorded the reports generation and typing times for both systems, using appropriate forms. RESULTS: When the mean times between both systems were compared, those from the electronic system presented a reduction of 20% (p = 0.0410) in the report generation time as compared with the traditional method. On the other hand, the traditional method was more efficient with respect to typing time, as the mean typing time with the electronic system was three times longer (p < 0.0001). CONCLUSION: The results demonstrated a statistically significant difference between the compared systems, with the electronic system being more efficient than the traditional one with respect to report generation time, while the traditional method presented better results with respect to typing time.
