Until recently only 1 out of 4 Americans experiencing a stroke were able recognize the symptoms and reach a hospital in time to limit the damage a stroke can cause if left untreated. Our F(ace drooping) A(rm weakness) S(peech dificulty) T(time to call 911) campaign communicated to a broad audience, in the simplest terms, how to recognize the signs of a stroke and what to do. By parterning with advocacy groups and stroke centers, we took our awareness campaign national and used social word of mouth to bring our campaign to the next level. When Major League Baseball heard about our campaign, they picked it up as the centerpiece for their Strike Out Strokes effort, appearing on baseball scoreboards throughout the country. Our campaign site saw a huge spike in traffic. The most important metric to us? The percentage of stroke victims who arrived at the hospital early enough to receive treatment increased for the first time in over two decades.
