  • COVID-19’s impact on interest in gastrointestinal topics

    by Michael B. Yan, Haig Pakhchanian, Rahul Raiker, Osama Boustany, Ahmad Khan, Shailendra Singh

    There has been a disparity in familiarity regarding the public interest in gastroenterology terminologies during the COVID-19 pandemic. This study aimed to understand the outcomes of the public’s view on gastrointestinal topics and their potential social effects. This study is a comparative analysis of American Google Trends gastrointestinal terminology during the COVID-19 pandemic compared to a similar time frame (March 2018-February 2020) to determine how trends in the patient-seeking behavior of gastrointestinal terminology changed throughout the pandemic. The analysis discovered a substantial decrease in search volumes of gastrointestinal topics, more significantly in the first pandemic months. Later in the pandemic, search volumes trended toward pre-pandemic years in terms of public interest. In the case of gastrointestinal procedures, endoscopy and colonoscopies, they surpassed pre-pandemic interest levels statistically (p-values of 0.01 and 0.002). The public’s decreased interest in gastrointestinal topics at the beginning of the COVID-19 pandemic may have adverse effects on the healthcare maintenance of patients who could have had a positive outcome in their gastrointestinal health with proper monitoring. Although gastrointestinal internet searches increased toward pre-pandemic levels as the seasons progressed, further research is needed to determine the social impact of decreased public interest.


  • Impact of COVID-19 on interest in hepato-pancreato-biliary diseases

    An important gap of knowledge exists regarding the public interest in hepato-pancreato-biliary (HPB) diseases during the coronavirus disease 2019 (COVID-19) pandemic. We aimed to understand the public interest in HPB diseases in the COVID-19 era. In this infodemiology study, we performed a comparative analysis of Google search volume of HPB terms in 2020–2021 and compared it to a similar time frame (2016–2019) in 3 periods to assess how trends in patient seeking behavior of HPB terms changed during the course of the pandemic in the USA and worldwide. Our analysis showed a substantial decrease in search volume of HPB diseases and procedure terms early in the pandemic. However, search volumes appeared to revert back to pre-pandemic years closer to the 1-year mark in USA and worldwide. Patients may have initially neglected HPB-related issues during the early phase of the COVID-19 pandemic, which could lead to worse outcomes. While HPB-related terms reverted closer to pre-pandemic levels later in the pandemic, further research is needed to assess the long-term impacts.
