We read with great interest the recent Platinum Priority editorial by Fode et al [1]. The authors express the opinion that the medical community should take measures to address the low quality of medical information on social media. We agree that the medical community should play their role in spreading correct, high-quality medical information. However, the authorities and the companies that run social media platforms should also respond to this issue with their own steps.With rapid developments in information technology, people can access almost any information at any time almost everywhere. In this situation, the spread of poor-quality information, even direct misinformation, can accelerate. Individuals without medical knowledge are more vulnerable to false information, as it is difficult for them to distinguish between what is true and what is false. This can result in serious consequences, including treatment delays, unnecessary treatment, and even failed treatment.In 2016, a college student in China who was suffering from a rare form of cancer had no choice but to search for hospitals that could treat this cancer on the internet [2]. On the basis of search results from a top search engine provider in China, he found a hospital in Beijing claiming that they had state-of-the-art technology to treat the cancer.Believing in the information provided by the search engine, he decided to receive the treatment in the hospital. However, application of this so-called “technology” had already been terminated in the USA because of poor results in clinical trials. The student died at the age of 22 yr after an ineffective treatment.This tragedy reminds us of the importance of supervision of the quality of medical information. It is important for social media companies and the authorities to do their own jobs. Social media companies should work closely with health care providers to review the medical information uploaded. If misinformation is identified, timely retraction is needed. Advertising for unproven or experimental medical technologies should be prohibited, as Google did in 2019 [3]. For accounts or IP addresses that upload false information, measures such as warnings, temporary bans, and even permanent bans should be considered. At the same time, promotion strategies for evidence-based medical information should be used by social media platforms to allow easier access for individuals, as it has been shown that professional medical information has a good effect [4], [5]. For the authorities, enacting laws to combat the spread of misinformation should be considered. Those who want to profit from uploading misinformation may think twice, as breaking laws would come at a huge cost. Medical institutions that provide false treatments should be subject to penalties such as revocation of their qualifications. With authorities and social media firms working together, the control of misinformation and tracking the sources of such information would be much easier.There is no doubt that individuals can benefit from high-quality, evidence-based medical information. However, low-quality information and direct misinformation are still growing quickly. It is important for the medical community, the authorities, and social media companies to contribute together to a better environment so that reliable information can flourish.The authors have nothing to disclose.This work was supported by the National Natural Science Foundation of China (grant number 81902727).
