[Quality parameters in the treatment of acute stroke: comparison of various regional treatment concepts]. / Qualitätsparameter der akuten Schlaganfallversorgung: Gegenüberstellung unterschiedlicher regionaler Versorgungskonzepte.

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. DISCUSSION: 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.

[Reality of acute stroke patient care in the metropolitan Ruhr area: status quo and perspectives of a stroke-specific network]. / Versorgungsrealität der Patienten mit ischämischem Schlaganfall im Ruhrgebiet : Aktueller Stand und Perspektiven einer fachspezifischen Vernetzung.

BACKGROUND: Networking structures are constructed to improve daily care of acute stroke patients, in the Ruhr area by the association of 26 neurological departments. Quality of care can be measured by the rate of stroke unit treatment and of thrombolysis. Epidemiological data are mainly derived from registers resulting in sparse insight into incidence and rate of specialized care in daily practice. METHODS: The study involved data analysis of diagnosis-related groups (DRG) statistics and structured quality reports for 2008 and 2010 for depiction of the quality of routine treatment. Aggregation of the number of cases for incidence, rate of stroke unit treatment and thrombolysis district, province, and nation wide were analyzed. RESULTS: In 5.2 million inhabitants, the incidence of ischemic stroke (ICD I63) was 296/100,000 in 2010 (district-wise range 244-364) and 56% of patients were treated on a stroke unit (range 18-80%; 2008: 43%, range 10-72%). The rate of thrombolysis (ICD I63) was 6.4% and 9.1% in 2008 and 2010 (2008 range 0-11.2%, 2010 range 3.9-18.0%), respectively, which was significantly above the provincial average in 10 out of 15 districts. DISCUSSION: Ischemic stroke is a common disease in the area and the quality of care (e.g. stroke unit treatment and thrombolysis rate) is above average. The heterogeneous character of the region allows an exemplary networking aiming for the improvement of routine patient care, e.g. by the implementation of homogeneous standards and structural measures for the implementation of novel therapies. The current analysis allows the identification of the potential for optimization and monitoring of any changes.
