title: [Quality parameters in the treatment of acute stroke: comparison of various regional treatment concepts].
abstract: BACKGROUND
  The long-term prognosis of stroke patients is still dependent in particular on the timing of a correct diagnosis, immediate initiation of a suitable specific therapy and competent treatment in a stroke unit. Therefore, nationwide attempts are being made to establish a comprehensive coverage of the necessary specific competence and infrastructural requirements. Divergent regional circumstances and economic viewpoints determine the characteristics of the various healthcare concepts and the interplay between participating cooperation partners. This article compares the development with respect to three qualitative treatment parameters exemplified by four regional healthcare models during the time period 2008-2011.
  
  
  METHODS
  The hospitalization rates for patients with transitory ischemic attacks, ischemic and hemorrhagic stroke, the case numbers for stoke unit treatment and the rates of systemic thrombolysis and mechanical thrombectomy in the regions of Berlin, the Ruhr Area, Ostwestfalen-Lippe and southeast Bayern (TEMPiS) are presented based on the data from the DRG statistical reports for the years 2008 and 2011.
  
  
  RESULTS
  The average hospitalization rates for ischemic stroke patients (brain infarct ICD 163) in the time period from 2008 to 2011 were 294 per 100,000 inhabitants for the Ruhr Area, 257 per 100,000 inhabitants for Ostwestfalen-Lippe and 265 per 100,000 inhabitants each for Berlin and southeast Bayern. The complex stroke treatment quota for southeast Bayern in 2008 was 31 % and 47 % in 2011 and the respective quotas for the other regions studied were 42-44 % and 58-59 %. The rate of systemic thrombolysis in 2008 ranged between 4.2 % and 7.4 % and in 2011 the increase in the range for the 4 regions studied was between 41 % and 145 %. In 2011 the thrombectomy quota of 2 % in the Ruhr Area was the only one which was above the national average of 1.3 % of all brain infarcts.
  
  
  CONCLUSIONS
  Stroke is a common disease in the four regions studied. For the established forms of therapy, complex treatment of stroke and systemic thrombolysis, the positive effect of structurally improved approaches in the four different regional treatment concepts could be confirmed during the course of the observational time period selected. Mechanical thrombectomy which is currently still considered to be an individual healing attempt, was used significantly more often in the Ruhr Area in 2011 than in the other three regions studied. A standardized referral procedure had previously been established in the metropolitan regions.
