ABSTRACT
BACKGROUND AND PURPOSE: Quality monitoring projects are useful tools to improve the quality and to assess temporal trends of stroke care in larger populations. METHODS: In Rhineland-Palatinate, Germany, a statewide, hospital-based, acute stroke care quality monitoring project was started in 2001. Initially, participation was mandatory for all hospitals with dedicated stroke units and from 2006 onward was mandatory for all hospitals. Quality monitoring included a structured data assessment and quality indicators for procedural measures. RESULTS: Between 2001 and 2006, the numbers of patients registered annually (N=6389 vs N=10 610), admission <3 hours after stroke onset (28.2% vs 34.6%), admission via emergency medical systems (38.1% vs 50.3%), and treatment in stroke units (44.3% vs 59.5%) increased significantly (P<0.0001, respectively). In ischemic stroke, use of thrombolytic therapy increased (for patients admitted <3 hours after onset, 6.5% vs 14.1%), whereas therapy with high-dose heparin declined (24.5% vs 6.0%, P<0.0001). Several quality indicators (performance of neuroimaging and Doppler/duplex sonography, neuroimaging <3 hours after admission) showed stable results at a high level; more patients received echocardiography (62.2% vs 74.0%), but fewer patients were rapidly examined by extracranial Doppler/duplex sonography (68.7% vs 62.8%, P<0.0001). Diagnosis and treatment of hypertension and hyperlipidemia, use of aspirin and combined aspirin/dipyridamole, and diagnosis of atrial fibrillation increased (P<0.0001, respectively). Use of oral anticoagulation remained stable at approximately 38% of patients with cardioembolism. CONCLUSIONS: Although these results reflect high standards of acute stroke care and improvements regarding early admission, thrombolytic therapy, and several secondary preventive measures, there is still the potential for further improvement regarding thrombolysis, use of oral anticoagulation and statins, and admission to stroke units, for example.

BACKGROUND AND PURPOSE: There is no consensus about indicators for measuring quality of acute stroke care in Germany. Therefore, a standardized process was initiated recently to develop and implement evidence-based indicators for the measurement of quality of acute hospital stroke care. METHODS: Quality indicators were developed by a multidisciplinary board between November 2003 and December 2005. The process was initiated by the German Stroke Registers Study Group in cooperation with the German Stroke Society, the German Society of Neurology, the German Stroke Foundation, Regional Offices for Quality Assurance and other experts proven in the field. National and international recommendations were considered during the development process. The process was based on a systematic literature review, an independent external evaluation of the process and its results, and a prospective pilot study to evaluate the defined indicators in clinical practice. RESULTS: Overall a set of 24 indicators was developed to measure performance of acute care hospitals in the 3 health care dimensions structure, process and outcome as well as in 3 treatment phases prehospital, in-hospital/acute and postacute. Practicability of the derived indicators was tested in a prospective pilot study. During a 2-month period, 1006 patients in 13 hospitals were documented. Application of the new indicator set was found to be feasible by participating physicians and hospitals. Median time to document the required information for 1 patient was 5 minutes. Nationwide implementation of the new indicator set within regional registers in Germany started since April 2006. CONCLUSIONS: The development of indicators to measure hospital performance in stroke care is an important step toward improving stroke care on a national level. The chosen standardized evidence-based approach ensures maximal transparency, acceptance and sustainability of the developed indicators in Germany.

CONTEXT: Data are limited regarding the risks and benefits of thrombolytic therapy for acute ischemic stroke outside of clinical trials. OBJECTIVE: To investigate predictors of in-hospital mortality in patients with ischemic stroke treated with intravenous tissue plasminogen activator (tPA) within a pooled analysis of large German stroke registers. DESIGN AND SETTING: Prospective, observational cohort study conducted at 225 community and academic hospitals throughout Germany cooperating within the German Stroke Registers Study Group. PATIENTS: A total of 1658 patients with acute ischemic stroke who were admitted to study hospitals between 2000 and 2002 and were treated with tPA. MAIN OUTCOME MEASURE: In-hospital mortality. RESULTS: One hundred sixty-six patients (10%) who received tPA died during hospitalization, with 67.5% of these deaths occurring within 7 days. Factors predicting in-hospital death after tPA use were older age (for each 10-year increment in age, adjusted odds ratio [OR], 1.6; 95% confidence interval [CI], 1.3-1.9) and altered level of consciousness (adjusted OR, 3.4; 95% CI, 2.4-4.7). The overall rate of symptomatic intracranial hemorrhage was 7.1% and increased with age. One or more serious complications was observed in 27.2% of all patients and in 83.9% of patients who died after tPA treatment. An inverse relation between the number of patients treated with tPA in the respective hospital and the risk of in-hospital death was observed (adjusted OR, 0.97; 95% CI, 0.96-0.99 for each additional patient treated with tPA per year). CONCLUSION: In patients with ischemic stroke who are treated with tPA, disturbances of consciousness and increasing age are associated with increased in-hospital mortality.
