Facebook effective in helping researchers recruit for clinical trials

Social networking site Facebook could be a valuable tool in recruiting patients for cardiac trials, according to researchers from the University of Alabama, MedPage Today reported. According to the researchers, a Facebook campaign about a cardiac arrest trial cost $1,000 and resulted in 5.1 million views and 437 visits to the study's website ($2.29 per visitor). A traditional campaign for a trial of hypertonic saline for major trauma that comprised 39 community meetings, meanwhile, cost $8,000, and garnered a total attendance of 465 participants, costing $17.24 per person.
