Valuable Features in Mobile Health Apps for Patients and Consumers: Content Analysis of Apps and User Ratings

Abstract

BackgroundThe explosion of mobile phones with app capabilities coupled with increased expectations of the patient-consumers’ role in managing their care presents a unique opportunity to use mobile health (mHealth) apps.ObjectivesThe aim of this paper is to identify the features and characteristics most-valued by patient-consumers (“users”) that contribute positively to the rating of an app.MethodsA collection of 234 apps associated with reputable health organizations found in the medical, health, and fitness categories of the Apple iTunes store and Google Play marketplace was assessed manually for the presence of 12 app features and characteristics. Regression analysis was used to determine which, if any, contributed positively to a user’s rating of the app.ResultsAnalysis of these 12 features explained 9.3% (R 2=.093 n=234, P<.001) of the variation in an app’s rating, with only 5 reaching statistical significance. Of the 5 reaching statistical significance, plan or orders, export of data, usability, and cost contributed positively to a user’s rating, while the tracker feature detracted from it.ConclusionsThese findings suggest that users appreciate features that save time over current methods and identify an app as valuable when it is simple and intuitive to use, provides specific instructions to better manage a condition, and shares data with designated individuals. Although tracking is a core function of most health apps, this feature may detract from a user’s experience when not executed properly. Further investigation into mHealth app features is worthwhile given the inability of the most common features to explain a large portion of an app’s rating. In the future, studies should focus on one category in the app store, specific diseases, or desired behavior change, and methods should include measuring the quality of each feature, both through manual assessment and evaluation of user reviews. Additional investigations into understanding the impact of synergistic features, incentives, social media, and gamification are also warranted to identify possible future trends.

Five key strategic priorities of integrating patient generated health data into United Kingdom electronic health records

“…More active promotion of incentives amongst less motivated users may also help. Such efforts could build on existing work surrounding perceived valuable features of mobile applications among the general population in order to promote lasting behaviour change 33. These may include repeat prescription ordering, appointment making and/or gamification techniques.…”

Sustainable Adoption of Digital Health Innovations: Perspectives From a Stakeholder Workshop (Preprint)

“…Thirdly, stakeholders launch initiatives with a lack of understanding of the basics of digital solutions. Usability was frequently mentioned as a main problem in digital solutions in healthcare even though there is a considerable amount of literature on developing user-centred and engaging interventions [17][18][19].…”

Self-Experiencing “The Healthiest Weight”

“…Experiment tracking was crucial. However, mobile technology allowed a close interaction [17], providing autonomy [8] and strengthening motivation [18]. While studies show that ~80% of people are not able to keep weight loss long, likely due to lack of motivation over time [3], the implementation of any choice of food/activity (personal preference vs pre-established diets/routines) and simple rewarding strategies are probably the keys for building up positive-thinking and long-term motivation [19], as well as successful habit-formation [20], achieved 8-10weeks after implementation.…”
