Clinical applications of videoconferencing: a scoping review of the literature for the period 2002–2012

We conducted a scoping review of the literature on the clinical applications of videoconferencing. Electronic searches were performed using the PubMed, Embase and CINHAL databases to retrieve papers published from 2002 to 2012 that described clinical applications of videoconferencing. The initial search yielded 4923 records and after removing the duplicates and screening at title/abstract level, 505 articles met the inclusion criteria and were reviewed at full-text level. The countries with the highest number of papers were the US, Australia and Canada. Most studies were non-randomised controlled trials. The discipline with highest number of published studies (39%) was mental health, followed by surgery (7%) and general medicine (6%). The type of care delivered via video comprised acute, sub-acute and chronic care, but in 44% of the papers, the intervention was used for a combination of these purposes. Videoconferencing was used for all age groups but more frequently for adults (20%). Most of the papers (91%) reported using videoconferencing for several clinical purposes including management, diagnosis, counselling and monitoring. The review showed that videoconferencing has been used in a wide range of disciplines and settings for different clinical purposes. The practical value of published papers would be improved by following standard guidelines for reporting research projects and clinical trials.
