During 2005-2007, engineers at the Department of Biomedical Engineering and Informatics, R&D at Nus developed a system for remote auscultations that can stream or store signals from a digital stethoscope. Assessments were thereafter done either during a video consultation or by recording and storing the sound for future assessment. The system was evaluated by specialists at the paediatric cardiology unit at Nus and the paediatric clinic in Skellefteå hospital. Evaluation of the trial showed that the system reduced the need for ultrasound examination of children with physiological heart murmurs, and made time for the specialists to address children with more severe cardiac disease. The service also contributed to shortening the waiting lists, reducing the need for staff and patients to travel, thus improving the overall resource utilization. Another important aspect identified was competence improvement of the paediatrician in Skelleftea with respect to assessment of heart murmurs.
Due to technical challenges, the system was idle for many years, but in 2016 an updated solution has been deployed and will make it possible for several units to further improve their telemedicine services.
