New meta-analysis of Z drugs published in the BMJ by REST team22/12/2012
The effectiveness of newer sleeping tablets, the Z drug (or non-benzodiazepine) hypnotics has been questioned because of publication and reporting bias in previous meta-analyses and the extent of the placebo response to hypnotics.
The study team analysed data submitted to the US Food and Drugs Administration (FDA) for drug approval. Publication bias was eliminated by combining the results of all pharmaceutical industry (‘pharma’) studies, published or unpublished, where a Z drug was compared to placebo. There were 13 studies containing 65 different comparisons of drug-placebo by type of outcome, type of drug, and dose, with 4378 participants from different countries, treatment lengths (mostly up to 30 days), and study years.
The study showed that Z drugs reduced the time to fall asleep in people with primary insomnia, both subjectively and measured in a sleep lab but the effects were relatively small (about 22 minutes). The placebo response was similar to the drug effect and the two together produced a reasonable clinical response. Around half the effect of the drug was a placebo response, which means the placebo response is important in this type of treatment.
There was no demonstrable effect of Z drugs on other outcomes, mainly because these studies tended not to measure sleep quality, daytime sleepiness or other outcomes which may be just as or more important to patients. Z drugs were more effective with larger doses but, more surprisingly, had greater effects in younger or female patients regardless of type of drug. Pharma trials tend to be more positive than non-pharma trials so we have to bear in mind that they tend to overestimate drug effects.
Around a fifth of older people get side effects from sleeping tablets and around one in a hundred will have a fall, fracture or road traffic accident after using them short-term. Cognitive behavioural therapy for insomnia works as well as sleeping tablets in the short term and is better and safer in the longer term so increasing access to these treatments for those who would benefit from them continues to be a priority.

New study on social networking platforms for computerised CBT-I07/12/2012
A new study investigating how computerised cognitive behavioural therapy (CCBT) can be enhanced through the use of social networking platforms was published in the British Journal of General Practice in December 2012. This qualitative study, funded by the EPSRC and conducted by members of the CaHRU team, Jo Middlemass, Dr Zowie Davy and Professor Niroshan Siriwardena, explored patient and practitioner perspectives on CCBT programmes for insomnia (CCBT-I) which would included social networking.
The objectives of the interview study were:
- To explore patient and professional perspectives, attitudes, expectations and beliefs towards online health care programmes;
- To identify participants’ preferences for content, style and information disclosure to health professionals or fellow sufferers;
- To investigate barriers and facilitators of access, use and adherence to CCBT with a focus on sleep problems and insomnia.
Two meta-themes emerged as key to enhancing uptake and adherence to a potential new CCBT-I package: the need for trust (in the programme, in the patient-professional relationship and in online peer support) and the functionality of the CCBT-I package, with potential users expressing a preference for it to be interactive, individualised and easily navigable.
The findings from the interview study have
been incorporated into a novel online CCBT-I package which is currently
undergoing testing, designed by a team led by Professor Shaun Lawson who
leads the Lincoln Institute of Social Computing (LiSC) with co-investigator Dr
Conor Linehan, both based in the

National insomnia expert comments on REST project01/07/2012 Professor Espie commenting recently on the REST project said: "I think the REST project is a tremendous initiative. For years, sleep has been a rather neglected topic in the NHS, although GPs know full well how common a problem insomnia is in every practice! This project provides practical evidence based help, and I would encourage GPs to make full use of it." Print
First placebo controlled trial of online CBT for insomnia published11/06/2012 The first placebo controlled trial of online CBT for insomnia has been published in the journal Sleep. The trial, led by Professor Colin Espie of Glasgow University, showed that CBT delivered using a media-rich web application with automated support and a community forum was effective in improving sleep and daytime functioning in adults with insomnia disorder.
