TY - JOUR T1 - Cochrane corner: text messaging to improve adherence to drugs for secondary prevention of cardiovascular disease JF - Heart JO - Heart SP - 1814 LP - 1816 DO - 10.1136/heartjnl-2017-312888 VL - 104 IS - 22 AU - Alma J Adler AU - Juan P Casas AU - Nicole Martin AU - Caroline Free AU - Pablo Perel Y1 - 2018/11/01 UR - http://heart.bmj.com/content/104/22/1814.abstract N2 - Despite numerous readily available low cost and effective medications for secondary prevention of cardiovascular disease (CVD), it has been shown that a substantial proportion of cardiovascular (CV) events in people with established atherosclerotic cardiovascular disease are due to poor adherence.1 Worldwide, at least 100 million people are thought to have prevalent heart disease, resulting in at least 13 million deaths each year. The majority of these deaths occur in low and middle income countries.2 Given the complexity of the problem and the variety of settings it occurs in, finding a feasible and scalable intervention to increase adherence poses challenges. Globally, there are over 7.5 billion mobile phone subscriptions, and even in low and middle income countries, the penetrance rate is over 90%. Some mobile short messages services (SMS) have been shown to improve medication adherence for chronic conditions such as HIV.3 SMS could be a potentially cost-effective and scalable intervention and do not require that the intended audience need to search for information as it is delivered to them, as opposed to health worker-based interventions that are more expensive and complex to deliver. SMS interventions are seen to be of particular interest in low and middle income countries, where it is difficult to deliver healthcare into rural and remote communities. SMS also has the advantage of having relatively few side effects.4 Despite great enthusiasm for using SMS-based interventions to improve adherence and improve health outcomes, the evidence is limited.5 In this summary, we report the results of a recent Cochrane review.6 While other systematic reviews have addressed the question of using mobile phones for all types … ER -
