[Topic identification for cross-sectoral quality assurance in stroke and TIA treatment]

The development of cross-sectoral quality assurance programs usually requires extensive topic identification. Illustrated by the complex processes of care for stroke and transient ischemic attacks (TIAs), a method for comprehensive topic identification is presented. The first step involves a thorough literature search in terms of systematic reviews, health technology assessments, guidelines, studies into healthcare delivery and the use of specific instruments. Routine data as well as epidemiologic studies are used to analyze the reality of service provision. In addition, experts are consulted to gain expertise concerning deficits of care, approaches to quality assurance and experience with existing quality assurance programs. Furthermore individual patient experiences are collected to add the patients' perceptions of care. Because of the limitation on the regulatory scope of Book V of the German Social Code, which, in this case, was necessary, another source of information was the legal framework and its impact on rescue chain, acute treatment and rehabilitation. Existent quality management systems, accreditations and quality assurance programs in prevention, acute treatment and rehabilitation have been searched in order to avoid any overlap with existing measures. After identifying a total of 71 quality targets according to deficits of care, recommendations for care and expert opinions in primary and secondary prevention, rescue chain, acute treatment, rehabilitation and supply of assistive equipment and therapies, respectively, the usability of instruments was tested. These instruments included case documentation, patient surveys and routine data. 14 quality targets proved to be reproducible by these instruments and were included in the recommendations for a cross-sectoral quality assurance program for stroke and TIA.

[Current aspects of secondary prevention of ischemic stroke]

Secondary prevention including lifestyle modulation and medical interventions remain the basic principle in our therapeutic challenge to reduce the risk of recurrent subsequent ischemic stroke. The substantial number of randomized clinical trials published in the past 2 years was broadened our evidence-based therapeutic armament in the field of secondary prevention of ischemic stroke. An update of current knowledge in secondary stroke prevention is presented in this review on the basis of the 2007 revised guidelines of the German Neurological Society and the German Stroke Society. Special emphasis is given to medical and nonmedical modulation of cardiovascular risk factors (treatment of hypertension, hypercholesterolemia, and diabetes mellitus), prophylactic vitamin supplementation, and the use of platelet inhibitors and treatment of symptomatic intracranial stenosis.
