The current status of stroke-related smartphone applications available to adopt in China: A systematic review study

Introduction: Stroke-related smartphone applications (apps) present enormous potential for stroke management as apps become increasingly prevalent in China. However, there is no comprehensive study reported about the currents status of stroke-related apps available to adopt in Chinese app market. The aim of this study is to assess the current status of stroke-related apps available to adopt in China. Materials and Methods: Using Stroke-related keywords written in either Chinese or English, the top 6 most prevalent apps online stores in China were searched from June to August 2018, including android market, 360 app market, wan dou jia, baidu mobile app, ying yong bao, apple app store. The basic features of selected apps were analyzed based on operating system, cost, target people, engagement, online interaction, release date, size, popularity, and usefulness. The information accountability of selected apps was evaluated with the Silberg scale. The functionality of selected apps targeting stroke patients at home were reviewed by researchers. Results: Our study showed that the downloads of stroke-related apps from android platform and the engagement of health professionals in apps development were critically insufficient. And most apps didn’t offer a platform to facilitate online interaction with health professional. The information accountability of apps also presented a huge room for improvement. The average Silberg score of 127 apps was 3.5 (out of 9) with most apps not disclosing sponsorship, authors’ affiliations, credentials, and sources or references of information. Few apps were modified in the past months. What's more, although the apps targeting stroke patients at home have covered 9 functionalities, most apps had only a simple functionality. Conclusion: This study identified areas for improvement concerning information accountability of stroke-related apps available for adoption in China and reviewed functionality of apps targeting stroke patients at home. The findings might guide the development for stroke-related apps in China in the future.
