Background
Telemedicine improves the quality of acute stroke care in rural regions with limited access to specialized stroke care. We report the first 2 years' experience of implementing a comprehensive telemedical stroke network comprising all levels of stroke care in a defined region.
Methods
The TRANSIT-Stroke network covers a mainly rural region in north-western Bavaria (Germany). All hospitals providing acute stroke care in this region participate in TRANSIT-Stroke, including four hospitals with a supra-regional certified stroke unit (SU) care (level III), three of those providing teleconsultation to two hospitals with a regional certified SU (level II) and five hospitals without specialized SU care (level I). For a two-year-period (01/2015 to 12/2016), data of eight of these hospitals were available; 13 evidence-based quality indicators (QIs) related to processes during hospitalisation were evaluated quarterly and compared according to predefined target values between level-I- and level-II/III-hospitals.
Results
Overall, 7881 patients were included (mean age 74.6 years +/- 12.8; 48.4% female). In level-II/III-hospitals adherence of all QIs to predefined targets was high ab initio. In level-I-hospitals, three patterns of QI-development were observed: a) high adherence ab initio (31%), mainly in secondary stroke prevention; b) improvement over time (44%), predominantly related to stroke specific diagnosis and in-hospital organization; c) no clear time trends (25%). Overall, 10 out of 13 QIs reached predefined target values of quality of care at the end of the observation period.
Conclusion
The implementation of the comprehensive TRANSIT-Stroke network resulted in an improvement of quality of care in level-I-hospitals.
Background: According to current guidelines, stroke patients treated with rt-PA should undergo brain imaging to exclude intracerebral bleeding 24 h after thrombolysis, before the start of medical secondary prevention. However, the usefulness of routine follow-up imaging with regard to changes in therapeutic management in patients without neurological deterioration is unclear. We hypothesized that follow up brain imaging solely to exclude bleeding in patients who clinically improved after rt-PA application may not be necessary.
Methods: Retrospective single-center analysis including stroke patients treated with rt-PA. Records were reviewed for hemorrhagic transformation one day after systemic thrombolysis and brain imaging-based changes in therapeutic management. Twenty-four hour after thrombolysis patients were divided into four groups: (1) increased NIHSS score; (2) unchanged NIHSS score; (3) improved NIHSS score and; (4) NIHSS score = 0.
Results: Out of 188 patients (mean age 73 years, 100 female) receiving rt-PA, 32 (17%) had imaging-proven hemorrhagic transformation including 11 (6%) patients with parenchymal hemorrhage. Patients in group (1, 2) more often had hypertension (p = 0.015) and more often had parenchymal hemorrhage (9 vs. 4%; p < 0.206) compared to group (3, 4) and imaging-based changes in therapeutic management were more frequent (19% vs. 6%; p = 0.007). Patients of group (3, 4) had no changes in therapeutic management in 94% of the cases. Patients in group (4) had no hemorrhagic transformation in routine follow-up brain imaging.
Conclusions: Frequency of hemorrhagic transformation in Routine follow-up brain imaging and consecutive changes in therapeutic management were different depending on clinical course measured by NHISS score.
Abciximab wurde, in Phase II-Studien, in der Behandlung der akuten cerebralen Ischämie erprobt und es erscheint bisher sicher und effektiv. Obwohl die Effektivität in der Abciximab in Acute Ischemic Stroke Studie nicht prospektiv untersucht wurde, ist jedoch ein Trend zu einem verbessertem Outcome zu beobachten. In unserer Untersuchung wurden 65 Patienten mit cerebralen Ischämien in verschiedenen Gefäßterritorien mit Abciximab behandelt. Die Patienten zeigten entweder Zeichen und Symptome einer Crescendo-TIA, eines progressive stroke außerhalb des "3-Stunden-Zeitfensters" für eine Thrombolyse oder eine erneute Verschlechterung nach zunächst erfolgreicher Thrombolyse. Alle Patienten wurden anhand der modified Rankin Scale (mRS) zum Zeitpunkt des Eintreffens in der Klinik und am Tag der Entlassung von der Stroke Unit untersucht. Ergebnisse: 88% der Patienten (57/65) verbesserten sich um im Mittel 2,3 Punkte bezogen auf die mRS. 71% der Patienten (46/65) erreichten eine mRS von 0-2. Es wurden keine fatalen oder symptomatischen intracerebralen Blutungen beobachtet. Fazit: In dieser nicht-randomisierten Untersuchung über die Akuttherapie der cerebralen Ischämie, zeigte die Behandlung mit Abciximab alleine oder in Kombination mit Thrombolyse eine klinische Verbesserung in 88% der Patienten. Blutungskomplikationen waren selten und nie schwerwiegend. Diese Ergebnisse unterstützen die Forderung nach weiteren placebokontrollierten, randomisierten Studien von Abciximab in der Akutbehandlung der cerebralen Ischämie.
