title: Can online benchmarking increase rates of thrombolysis? Data from the Austrian stroke unit registry.
abstract: Despite its widespread availability and known safety and efficacy, a therapy with intravenous thrombolysis is still undergiven. We aimed to identify whether nationwide quality projects--like the stroke registry in Austria--as well as online benchmarking and predefined target values can increase rates of thrombolysis. Therefore, we assessed 6,394 out of 48,462 patients with ischemic stroke from the Austrian stroke registry (study period from March 2003 to December 2011) who had undergone thrombolysis treatment. We defined lower level and target values as quality parameters and evaluated whether or not these parameters could be achieved in the past years. We were able to show that rates of thrombolysis in Austria increased from 4.9% in 2003 to 18.3% in 2011. In a multivariate regression model, the main impact seen was the increase over the years [the OR ranges from 0.47 (95% CI 0.32-0.68) in 2003 to 2.51 (95% CI 2.20-2.87) in 2011). The predefined lower and target levels of thrombolysis were achieved at the majority of participating centers: in 2011 the lower value of 5% was achieved at all stroke units, and the target value of 15% was observed at 21 of 34 stroke units. We conclude that online benchmarking and the concept of defining target values as a tool for nationwide acute stroke care appeared to result in an increase in the rate of thrombolysis over the last few years while the variability between the stroke units has not yet been reduced.
