#Mesh: Social Media and Its Influence on Perceptions in Hernia Repair.

Social media can influence public perception in health care. By 2016, social media discussion against the use of transvaginal mesh influenced changes in Food and Drug Administration (FDA) regulations. We propose that the fate of hernia mesh will follow that of transvaginal mesh. Thus, we compare the trend of social media discussion of hernia and transvaginal mesh. Posts on Twitter and public Facebook groups were tracked for keywords "hernia," "hernia mesh," and "pelvic/vaginal mesh." Posts were categorized based on sentiment. On Facebook, 16 public groups with 14 526 members expressed negative sentiments in 95% of their 750 daily posts. Meanwhile, of the 1.1 million tweets on Twitter, those about hernia mesh were more negative (36.5%) than those about pelvic/vaginal mesh (29.2%). Three of the 5 top tweeters about hernia mesh and pelvic/vaginal mesh were linked to law firms involved in mesh-based lawsuits. The negative sentiments and steering of social media discussion by lawyers may directly affect surgical care. As surgeons, we may adapt our informed consent to acknowledge our patients' apprehensions about mesh. We may also be more involved in social media discussions ourselves. Meanwhile, we await FDA decisions in the regulation and availability of hernia mesh.
