Health information sharing on social media: quality assessment of short videos about chronic kidney disease

Abstract

INTRODUCTION: Chronic kidney disease (CKD), which affects about 10% of global population, has become a global public health crisis in recent decades. It is well recognized that health information dissemination could change health behaviors, thereby greatly improving the early diagnosis and prevention of diseases. Due to fast dissemination, wide audience, intuitive and vivid, popularization through short videos has rapidly developed into the new main battlefield of health information. The objective of this study was to describe the properties of the CKD-related health information on short video apps. METHODS: Searching on short video apps with high-frequency words in kidney disease as keywords, the basic information of the uploaders was retrieved and extracted short video. Five quality dimensions, awareness, popularity, utility, validity and quality, of each video were assessed with numeric rating scale (NRS) by five volunteers with CKD and three nephrologists. RESULTS: From the platform of douyin, 65 uploaders and their 3973 short videos of CKD-related health information were investigated in this study. Most information of short videos had relatively high level in awareness, popularity and utility assessment, but some information had relatively low level in validity and quality assessment; 24 (36.9%) uploaders were from governmental hospital (tertiary hospital); 19 uploaders (29.2%) uploaded more than 100 short videos and 49 uploaders (75.4%) updated their videos weekly, and 16 uploaders (24.6%) didn't update short videos more than one month. There were 4 uploaders (6.2%) have more than 1 million follows, and 39 uploaders (60%) had follows less than 10,000. "Lifestyles", "Common symptoms of kidney disease" and "Nephritis or kidney disease" were the three main contents of these short videos. The comprehensive data of uploaders with millions of follows in nephrology specialty were much lower than that of orthopedics and other specialty. CONCLUSION: The validity and quality of short video is still unsatisfactory, and CKD-related health information also need to be led and improved, although the awareness, popularity, and utility of health information about CKD is acceptable. The public should be selective and cautious in seeking CKD information on social media.
