Evaluation of a training and diagnostic ultrasound service for general practitioners using narrowband ISDN.

Abstract:

:We carried out a four-month pilot study of telemedicine for the delivery of training and diagnostic ultrasound services for general practitioners (GPs). Two health centres and a district general hospital were linked using ISDN (128 kbit/s) and PC-based videoconferencing units. Sixteen videoconferencing sessions were conducted, with 64 patients scanned over the ISDN link for a range of clinical conditions. Nine cases of pathology were demonstrated and confirmed by a consultant radiologist. A total of 229 images were transmitted using the store-and-forward facility, of which 194 (85%) images were of diagnostic quality and 35 (15%) were regarded as non-diagnostic. Allowing for sampling error, we would expect 79-89% of stored images to provide diagnostic information at a 95% confidence level. A total of 115 store-and-forward images (SAFI) were randomly selected and compared with hard-copy images (HCI) for technical quality. There was a significant difference in the quality of images. The results show that SAFI are far superior to HCI, traditionally used by clinicians for making primary diagnosis and that the superior quality of the SAFI improved diagnostic accuracy. This pilot study showed a high degree of confidence in videoconferencing for training GPs to carry out ultrasound clinics, enhancing their ability to make accurate diagnoses, and providing them with immediate access the second and higher opinion.
