VideoconferencingDepressionRandomized controlled trial/intervention study
N=107 patients
Videoconferencing is a feasible care delivery modality in clinically unsupervised settings for depressed outpatients. Severity of depression decreased significantly in both the videoconferencing (F2=26.57, p<.001) and FTF (F2=29.99, p<.001) groups.
Videoconferencing showed improvements in patient outcomes, therapeutic relationship satisfaction, low defaulting, and medication compliance. However, treatment adherence was comparatively low (X21 =2.864, p=.07).

Tele-education, video conferencingGeneral mental health issues and care deliveryAction research study
N=9 (4 psychiatrists, 5 medical officers
Videoconference education with a flexible format, administration and technical support improvement was beneficial to health staff with low psychiatry qualification/training.
A bandwidth of 128 Kilobytes per second (Kbps) is required for tele-education while 384Kbps is more reliable for tele-consultation. Keys to developing new telepsychiatry services include awareness creation, practitioner acceptance, understanding physician/patient clinical needs, and onsite technical support and local coordination service provision.
