Here, I\u2019ll share what I learned about health apps.<!--more--><\/p>\n<p><strong>Health apps to measure, record, nudge, and influence<\/strong><br \/>\nPHE has articulated a need for digital health products (\u201capps\u201d) to help people take personal responsibility for their health, improve efficiency in NHS care pathways, and meet demands on the NHS. Population level measures are expanding from primary prevention to self-care in long term conditions. Correspondingly, health apps have shifted from merely raising awareness of the need to change to supporting people to actually change.<\/p>\n<p>They can do this in a number of ways. Apps can collect, share, and feed back\u00a0 information, adapting as people exhibit different levels of sickness. An example discussed at the conference was <a href=\"https:\/\/www.lifeguideonline.org\/player\/play\/stopadvisordemonstration\">StopAdvisor<\/a>, an internet based, &#8220;automated adviser&#8221; that was subsequently developed into an app that helps low socioeconomic status (SES) smokers to quit. According to Professor Susan Michie from UCL, it was developed based on four elements: evidence on the efficacy of particular interventions, web design, person centredness, and behaviour change theory. This method, it seems, is not the norm because most app developers rarely draw on the science.<\/p>\n<p><strong>Sorting the wheat from the chaff: app accreditation<\/strong><br \/>\nWith around 200 000 apps, the digital health landscape is a complex one, in which we need some clarity about what is a good product. The PHE team, we were told, commissioned a systematic review of app accreditation methodologies currently in use, which concluded that there were, well, none. The same review, which evaluated 47 smoking cessation apps, also reported that the more popular apps (higher display ranking in the store) were of lower quality (conformed less well to relevant guidelines). It concluded that the health apps market is not working.<\/p>\n<p>Cue an interesting initiative led by <a href=\"https:\/\/www.gov.uk\/government\/organisations\/national-information-board\">the National Information Board<\/a>,\u00a0which brings together PHE, NHS England, NHS Digital, and the National Institute for Health and Care Excellence (NICE), among others. It aims to accredit specific apps using recommended methodologies, so that health apps with a solid evidence base will be promoted and used. The endorsement model involves three stages: firstly, self-assessment against a range of criteria (for example, effectiveness, safety, equality, usability); secondly, community evaluation (for example,\u00a0by health and IT practitioners, the third sector); and, finally, an expert evaluation by NICE, to include considerations such as\u00a0cost effectiveness. This is all still in the development stages, but the idea is to have an NHS rubber stamped library of apps accessible to clinicians and the general public.<\/p>\n<p><strong>Future considerations<\/strong><br \/>\nWhen it comes to technology, are you an early adopter or a laggard? Maybe you\u2019re the innovator. Each group within the spectrum has its value, and the conference raised a number of questions and thoughts about the consequences of some of these digital interventions. For example: you have the data, but what will you do with it? How do you transform a bunch of apps into better health outcomes? What about information governance and regulation? Who do you trust more with your data\u2014the commercial sector or the NHS? There are also logistical considerations, for example, about data storage and technology becoming obsolete. There\u2019s the essential question of how to measure effectiveness; and then there\u2019s the human element. How will technology truly capture the human experience? What about user boredom or unintended harms? What about <em>un<\/em>healthy influences competing for the same digital space?<\/p>\n<p>The process of developing and accrediting digital health products will be an iterative one, and you can\u2019t think of every possible outcome at the start, but it\u2019s reassuring that people are trying. In fact, to help us navigate the subject, there\u2019s <a href=\"https:\/\/publichealthmatters.blog.gov.uk\/2016\/07\/22\/%EF%BB%BFthe-a-z-of-digital-public-health\/\">an A-Z of Digital Public Health<\/a>, an online lexicon of often ordinary words that have marvellously taken on new, digitally oriented meanings: words such as\u00a0&#8220;agile,&#8221; &#8220;waterfall,&#8221; &#8220;scrum,&#8221; and\u2014my favourite\u2014&#8221;retirement.&#8221;<\/p>\n<p><strong>Final thoughts<\/strong><br \/>\nThe developments discussed at the conference subvert the view that technology makes us inactive and unhealthy. But neither should it be regarded as a quick fix cure for the nation\u2019s ills. It\u2019s up to us to decide how we use technology, and if we can use it to influence behaviour that improves health, particularly where health practitioners can\u2019t extend their reach, then that seems like a good thing. \u201cEvidence into Action\u201d was the theme of this year\u2019s conference, and to make that work for digital health\u2014to keep it real and joined-up\u2014end users and health practitioners really need to be involved in this conversation.<\/p>\n<p>Many thanks to Dr Mary E Black, head of strategy, digital, PHE; Mr. Simon Dixon, mobile strategy lead, PHE; and all the speakers.
