Apps using behavioural techniques to reduce nonadherence
Over the past two decade, reducing nonadherence to medication has sought solutions in smartphone apps embedded with psychological techniques to encourage users to change their behaviour. Recent studies suggest that 90% of total time on mobile phones is being spent on apps and individuals may spend an average of 30 hours per month on apps. Such preoccupation raises the possibility that apps could be utilized by healthcare providers and their patients to reduce nonadherence. Behavioural science’s signature policy is set out in the 2008 book ‘Nudge’, which looks at how people make decisions and applies this to healthcare. Nudges are a particular type of behaviour change intervention, which steer people in certain directions while maintaining their freedom of choice. The key insight is that changing the way choices are presented to people can have a significant impact. We end this Commentary by briefly describing some studies that have examined apps embedded with ‘nudge’ techniques to address the nonadherence to medication challenge. But first, we describe the rise in the influence of behavioural techniques in health policy.
The rise in the influence of behavioural techniques on health policy
In the early 2000s, both the US and UK governments began to explore how psychological and behavioural techniques could be used to improve public policy and healthcare, while maintaining a significant element of personal choice. In 2003, policy makers in the US were influenced by a paper entitled ‘Libertarian Paternalism’, published in the American Economic Review. Its authors, Richard Thaler, a University of Chicago economist and Cass Sunstein, a Harvard University Law School professor, suggested that it is both possible and legitimate for private and public institutions to influence people to make decisions about health and wellbeing without coercing them. In February 2004, the UK’s Prime Minister’s Strategy Unit, published a report entitled ‘Personal Responsibility and Changing Behaviour: the state of knowledge and its implications for public policy’, which described behavioural theories of change and explored ways the government might employ psychological techniques to influence personal behaviour in order to improve public policy. In 2008, Thaler and Sunstein published a book entitled ‘Nudge’, which described how behavioural techniques and mental processes could be used to ‘nudge’ people and groups, rather than ordering them, to do things expected to improve public policy and reduce costs. In 2009, the US government recruited Sunstein to head the Office of Information and Regulatory Affairs (OIRA) and streamline regulations. In 2010, UK Prime Minister David Cameron established the Behavioural Insights Team (BIT) (referred to as the ‘Nudge Unit’) in 10 Downing Street, which was headed by David Halpern, the first author of the 2004 Strategy Unit Report referred to above. This was the first formal and systematic application of behavioural insights to public policy. In 2014, President Obama set up a similar unit - the Social and Behavioral Sciences Team - in the White House. Over the past decade, similar units have been set up by governments throughout the world, the word “nudge” and ‘Nudge Units’ have become common place in social and public policy, and the application of behavioural techniques, have become a significant aspect of public sector management. Nudge techniques have been employed to reduce the burden of nonadherence to medication.
Apps to nudge people to adhere to medication
Over the past decade, there has been a plethora of apps launched to tackle nonadherence to medication. A December 2015 study published by the UK’s Health Foundation entitled Behavioural Insights in Healthcare, suggested that “nudge-type” interventions could, “improve rates of medication adherence, particularly for chronic conditions”. In September 2018, Public Health England published a similar report entitled, Improving People’s Health: Applying behavioural and social sciences to improve population health and wellbeing in England. These and other studies reflect the prominence gained in recent years of the potential benefits behavioural and social sciences can make to improving peoples’ health.
Limited use of ‘nudge’ techniques
A research paper entitled, “Behavior Change Techniques in Apps for Medication Adherence” published in the May 2016 edition of the American Journal of Preventative Medicine drew attention to the vast and growing number of apps promoting medication adherence available in the two largest app repositories: the Apple App Store and the Google Play Store. The authors identified and coded 166 medication adherence apps according to 96 established behaviour change techniques and found that the apps only used a limited number of these, and “do not appear to have benefitted from advances in the theory and practice of health behaviour change”. The most commonly included behaviour change techniques were “action planning” and “prompt/cues,” which were included in 96% of apps, followed by “self-monitoring” (37%) and “feedback on behaviour” (36%). The authors of the study concluded that the apps did not appear to have benefitted from “advances in the theory and practice of health behavioural change”.
Four research studies conclude that apps are using behavioural techniques sub-optimally
Four research papers published between 2017 and 2020 in the Journal of Medical Internet Research assessed thousands of apps embedded with behavioural techniques to address medication adherence in different regions of the world and all reached similar conclusions to the 2016 paper in the American Journal of Preventative Medicine mentioned above: that apps designed to enhance medication adherence use ‘nudge’ techniques sub-optimally. In the April 2017 edition of the Journal of Medical Internet Research, a paper entitled “Assessing the Medication Adherence App Marketplace from the Health Professional and Consumer Vantage Points”, identified 824 adherence apps and evaluated 645 of them. Researchers found that the quality of the apps “varied considerably”. A 2018 review paper published in the same journal, provided one of the first comprehensive assessments of medication adherence apps in terms of their evidence base, medical professional involvement in their development and the strategies they used to facilitate behaviour change and improve adherence. Researchers identified 5,881 apps, tested 1,486 according to predetermined criteria and concluded that there was, “a concerning lack of healthcare professional involvement in app development and evidence base of effectiveness”. A paper entitled, “Using Health and Well-Being Apps for Behavior Change” published in the July 2019 edition of the Journal of Medical Internet Research, provides a systematic review of a large sample of healthcare apps marketed in Australia. The initial search identified 212,352 apps, from which 5,018 were identified using a priori key search terms. Of these, 344 were classified as behaviour change apps and were reviewed and rated. Conclusions suggested that only a limited number of the apps were found to be using behavioural change techniques expected to promote and sustain lifestyle behavioural change and improved health. And finally, a research paper entitled, “Quality, Functionality, and Features of Chinese Mobile Apps for Diabetes Self-Management: Systematic Search and Evaluation of Mobile Apps” published in the April 2020 edition of the Journal of Medical Internet Research evaluated apps that are available to millions of people in China living with diabetes and designed to help them self-manage essential medications they are required to take regularly throughout their lives. Among 2,072 apps identified, 199 were selected based on the authors’ criteria and 67 apps were analysed. Conclusions were similar to those in the previous studies mentioned in this section and suggested that the, “general quality” of the apps was “sub-optimal”.
Takeaways
Nonadherence to medication is a vast and rapidly growing killer epidemic, which is under reported, under-treated and cost healthcare systems billions. This is partly because no healthcare stakeholder has assumed responsibility for denting the burden of the epidemic. Thus, nonadherence is an orphan issue. More recently, the confluence of mobile telephony and behavioural techniques has held out a promise to reduce nonadherence. However, research has suggested that while there is a proliferation of mobile apps embedded with behavioural techniques specifically designed to lower the burden of nonadherence to medication, the overwhelming majority of these are not using tried and tested behavioural techniques optimally. This suggests that there is an opportunity to significantly improve nonadherence to medication by optimally utilising behavioural techniques and digital technology.
