Google Trends as a resource for bariatric education: what do patients want to know?

ABSTRACT

BACKGROUND: Bariatric surgery (BaS) is the safest, most effective, and most durable therapy for obesity but is performed in less than 1% of the affected United States (US) population. It is challenging to determine from traditional surveys if this phenomenon is the result of poor access to care or lack of interest among Internet users. OBJECTIVES: The aim of this study was to use Google Trends (GT) as a tool to analyze the US general population interest in BaS. SETTING: Academic Hospital, United States. METHODS: GT was used to access data searched for the term bariatric surgery. The gathered information included data from 2008 through 2018 in English within the US. Search frequency, time intervals, locations, frequent topics of interest, and related searches were analyzed. GT reports search frequency on means, and a value of 100 represented peak popularity. RESULTS: The number of Google searches related to the term bariatric surgery has gradually increased over time, from a mean of 67% in 2008 to a 94% interest in 2017. Regarding interest by subregion in 2017, the state of Michigan lead the frequency of searches, followed by Indiana, Delaware, West Virginia, and Tennessee. Top searched terms by frequency were the following patient eligibility for BaS, what is BaS, what are the complications of BaS, financial costs of BaS, and what insurance companies cover BaS. It appears that traditional Web sites only address a few. CONCLUSIONS: GT complements the understanding of interest in BaS. Using these trends can improve an Internet user's education, and tailor specific official Web sites for the public's general interest.
