Smoking leading cause of preventable death
Txt2stop
5800 smokers willing to quit
Allocated to txt2stop or control
Doubled biochemically validated quitting at six months
10.7% txt2stop versus 4.9% control, relative risk 2.20 (95% CI 1.80 to 2.68), p<0.0001.
Implemented UK with over 48,000 users since 2012

Systematic review of trials of mobile technology based interventions for health or
health care Promising results• Physical activity (only short term), hypertension• Appropriate disease management for providers
(11/25 outcomes showed statistically significant benefits)
Clear small benefits• appointment reminders. Mixed results few trials .e.g. asthma No clinically important benefits• Weight loss• Daily medication reminders RR 1.00 (95% CI
0.77 to 1.30)

Summary
• Where there is good evidence of benefit strong implementation plans are needed e.g. smoking cessation
• Lack of evidence in many areas for NCD
• New and improved NCD interventions needed.
• Well designed and adequately powered trials to demonstrate the effectiveness of interventions are needed in many areas.
