The size of the problem estimated 26% of the population of England (38% of men and 16% of women aged 16 – 64) drink hazardously or harmfully, equating to approximately 7.1 million people in England alone associated with physical problems, mental health problems, antisocial behaviour, violence, accidents, suicides, injuries, road traffic accidents, unsafe sexual behaviour, underperformance at work or school, and crime cost to the NHS alone calculated as £1 billion – £2 billion
Alcohol Needs Assessment Research Project (ANARP) fewer than 1 in 18 people with an alcohol misuse disorder in the UK have access to appropriate treatment Digital interventions may assist in reducing this discrepancy
The Background 1986 Evaluation of a self-help manual for media-recruited problem drinkers: Six-month follow-up results Nick Heather *, Barbara Whitton 1, Ian Robertson 1987 (or thereabouts) Alcohol Services Pontefract & Wakefield 1988 The DYD 6 week postal programme 2001
Key Features Home Page Screening Questionnaire (FAST) (on screen feedback) 6 sequential weekly modules Online Drinking Diary Alcohol Consumption Calculator BAC calculator Personal thinking drinking log Intelligent email
50,000 leaflets outlining the main features of DYD were distributed as inserts in GP magazines Launched at the AERC annual conference in Edinburgh with associated press releases Listings in Health Publications & BBC website Registration with Yahoo Search Engine
Down your drink: a web-based intervention for people with excessive alcohol consumption. Linke S, Brown A, and Wallace P Alcohol and Alcoholism 2004 Jan-Feb;39(1):29-32. RESULTS: During the 6-month study there were 7581 visits to the site and 1319 registrations. Of the registrants, 61.8% completed week 1, and 6.0% stayed with the programme until the end. The 6% who stayed for 6 weeks provided encouraging feedback about the value of the site.
you dont tell people off or come up with scare tactics (participant 6) I particularly appreciated the non-judgmental attitude of the course – it is helpful to know that the aim is not to cut alcohol out of ones life completely. (participant 8)
I am learning from my mistakes. I think a lot about how I drink alcohol, what triggers are involved and have started to try and avoid drinking, when I do drink I go to a good wine and sip slowly. (participant 47)
The DYD-RCT protocol: an on-line randomised controlled trial of an interactive computer-based intervention compared with a standard information website to reduce alcohol consumption among hazardous drinkers BMC Public Health 2007, 7:306 doi:10.1186/1471-2458-7-306 Elizabeth Murray (email@example.com) Jim McCambridge (Jim.McCambridge@lshtm.ac.uk) Zarnie Khadjesari (firstname.lastname@example.org) Ian R White (email@example.com) Simon G Thompson (firstname.lastname@example.org) Christine Godfrey (email@example.com) Stuart Linke (firstname.lastname@example.org) Paul Wallace (email@example.com) MRC Complex Interventions Framework Phase 2/3 trial
2-arm trial - comparison with information only website Primary Outcome - total past week alcohol consumption at 3 months Secondary outcomes questionnaires hazardous or harmful drinking dependence harm caused by alcohol mental health health economic analysis Randomisation to secondary outcome measures to minimise assessment burden Online Trial – but offline details requested for follow up Primary analysis based on completers, not ITT
Methodological Challenges Recruitment to ensure sufficient statistical power What constitutes an adequate comparison and what are we controlling for? How do we detect multiple registrations and how do we deal with them? How do we minimise attrition from: the intervention (stickiness) the trial (problem of missing data) What constitutes an adequate intervention dose or exposure and how can this be measured? Does online assessment behave in the same way as conventional assessment?
Changes to the Intervention Removed the lock out and 6 week structure Explicit Psychological Treatment Model Updated the look and feel and images The new site was runner up for the NHS London Innovations Award
Content Self Assessment and Automated Feedback 3 Phases: Its Up To You (Motivational Interviewing) Making the Change (Behavioural Self Control & Cognitive Behaviour Therapy) Keeping on Track (Relapse Prevention)
MAIN RESULTS. Mean age was 37yrs 57% were women 52% educated to at least degree level. The majority identified themselves as white British (84%) All the participants were drinking hazardously at the beginning of the study (geometric mean of 46 units per week) This reduced to 26 units at 3 months and maintained at 12 months The same changes happened in both groups.

DYD is very popular! Pilot Study-1300 Naturalistic Cohort Study-10000 Trial-7935
DYD use since finishing the trial 78.04% New Visitor 21.96% Returning Visitors
What do the results mean? Lots of people register - only a few make full use of the intervention (dose) – but many dramatically reduce their drinking Users do not distinguish between the intervention assessments and being in the trial (reactivity) Users are probably look for help and are highly motivated to change (regression to the mean) and dont just use DYD
What is the role of digital interventions There are now many alcohol interventions on a range of different platforms Apps and websites can be embedded within social networks, medical information systems and public educational material. We need a strategic approach to the application of this technology recognising: –The rapid speed of change –The continuing digital divide –The level of noise in the IT/Communications age
Current and Future Projects Occupational settings –We are currently analysing the data from a trial with a large multinational company. –Alcohol Health Network – Don Shenker EFAR and ODHIN
Increasing Access through Primary Care –Pilot implementation study in Kingston (Murray et al 2012) Dedicated URL Referral by GP Dedicated worker providing facilitated access –Islington IAPT (Improving Access to Psychological Therapies) Primary Care Mental Health Workers offering routine Screening and Brief Interventions and signposting to DYD
ODHIN Optimizing delivery of health care interventions
