[Certification criteria for stroke units in Germany : Update 2018].

This article describes the revised criteria for certified stroke units (SU) in Germany that will apply from 1 October 2018. Due to the high level of quality only minor adjustments and specifications were necessary in many places and the majority of criteria remained unchanged. For the first time a uniform personnel quota of ≥1.75 full-time staff per monitor bed is defined, which is a better reflection of the treatment reality. The evidence-based process of acute vascular imaging using computed tomography angiography (CTA) and alternatively magnetic resonance angiography (MRA) is now defined as a minimum rate of≥20 % of all brain infarcts. In this way the timely identification of suitable candidates for endovascular thrombectomy (ET) should be accomplished. Ultrasound diagnostics of arteries supplying the brain remain an integral part of additional diagnostics after cerebral ischemia because this generates supplementary information. The extended detection of atrial fibrillation is newly included as a diagnostic minimum standard and necessitates measures that go beyond a single long-term electrocardiograph (ECG). In order to facilitate the certification of telemedically supplied SU (Tele-SU), the minimum standard of stroke patients was reduced to ≥200 per year. A Tele-SU in the immediate catchment area of a certified SU (<20 km) must provide proof of a regional treatment need in order for certification to be approved. Quality criteria in the audit reports have now a greater importance. They require a concrete plan of action, which must be tracked within the framework of the interim report and must be presented for the recertification. Furthermore, the SU are called upon not to limit the endeavors for quality only to the minimum requirements.
