Change in stroke outcome with tPA

This shows 13% full success but I've been using the 12% tPA efficacy one, your doctor should be able to explain their hospital rate of efficacy of tPA.
The diagram came from here: A CME course on Opening the Window of Time in Stroke Therapy: New Evidence for the Emergency Department
That amount of failure should have created an emergency project back in 1996 to figure out a better solution. But NO, we've been shoehorning this failure into stroke processes ever since.  I blame our stroke associations for putting out 'happy talk' rather than informing the world that everything in stroke is a failure. 68% failure rate is abysmal, everyone in stroke needs to be fired, they've had almost 20 years to fix this and have done nothing..
