Abstract
|
|
|
Objectives: To review the recent trend of randomized controlled clinical trials on insomnia and to provide information for future clinical trials.
Methods: A total of 667 pieces of literature were searched using the key words ’insomnia’ and ’randomized controlled trial’ and using the title ’insomnia’ with the topic ’trial or trials’, published from 2008 to 2012 through Web of Science. Studies including randomized controlled clinical trials were sorted from the search result and finally 104 pieces of the literature were selected and examined.
Results: Besides 104 clinical trials, 14 trials related to CAM (Complementary and Alternative Medicine) were also reviewed. On average, 20 trials were annually conducted and they showed a growing trend. Participants were between 31 and 90 (34.6%), and were observed for less than 30 days (28.8%) in most trials. As intervention methods for clinical trials, non-pharmaceutical methods were used in 59 studies (56.7%), pharmaceutical drug in 43 studies (41.3%) and combinations in 2 studies (1.9%). In 60 studies, only insomnia without any underlying diseases was examined and other 44 studies involved other diseases. As diagnosis assessment tools, Sleep diary and Polysomnography were used.
Conclusions: Randomized controlled trials relevant to insomnia were on the increase, but only a small number of clinical trials on Oriental Medicine have been performed. Larger scientific and well-founded randomized controlled trials are required for developing Oriental Medicine and establishing high-quality guideline going forward.
