Health disparities and clinical trial recruitment: Is there a duty to tweet?

While it is well known that the homogeneity of clinical trial participants often threatens the goal of attaining generalizable knowledge,researchers often cite issues with recruitment,including a lack of interest from participants,shortages of resources,or difficulty accessing particular populations,to explain the lack of diversity within sampling. it is proposed that social media might provide an opportunity to overcome these obstacles through affordable,targeted recruitment advertisements or messages. recruiters are warned,however,to be cautious using these means,since risks related to privacy and transparency can take on a new hue. © 2017 caplan,friesen.
