A study of the effectiveness of a brain stent, designed to reduce strokes, instead caused so many more strokes in patients (14.7%) than a control group (5.8%) that the study was quickly halted. The expensive stents had been approved by the FDA under a humanitarian exemption from usual safety reviews. The stent has been implanted in thousands of patients.
The study adds to a growing set of evidence that medical treatments are not always based on the best evidence of safety, effectiveness or cost effectiveness. To learn more about comparative effectiveness research and evaluations of treatments, join us for a webinar with CEPAC September 30th.
