A new era of seeking knowledge for #lymphedema on social media: A detailed Instagram hashtag analysis.

Instagram® is one of the most active social media platforms with over a billion users worldwide. Since the importance of education on lymphedema has been established due to the chronic nature of the disease, seeking knowledge attracts much attention not only clinically but also on social platforms such as Instagram ®. Our aim was to examine content by analyzing posts tagged with hashtags on Instagram ® related to lymphedema. Nine predefined hashtags related to lymphedema were used to search posts uploaded to Instagram® via the Apify tool. Retrieved public posts were classified and analyzed by four researchers for their content and post-type. We found that the vast majority of sharing on Instagram® in the context of lymphedema and its related aspects have relatively low scores for both relevancy and accuracy with a 77% irrelevancy rate. The best posts were those determined to be educational, which were found 57% relevant and correct. Medical professionals should consider that disseminating true guidance and therapy carries importance for patients with lymphedema and treatment success. The ability for patients to reach knowledge via social media might also be an important aspect in reliving suffering due to lymphedema. However, our results demonstrate that Instagram® might not be a good platform for patients to discover reliable information about lymphedema.
