Abstract

Providing stroke unit treatment for all stroke patients is a cross-national goal as stated in the WHO Helsingborg Declaration. In order to achieve specialized stroke care for a large area, two stroke centers and 12 community hospitals established an integrative stroke network. This evaluation was performed to analyze achieved advances in stroke management. Core network elements are: (1) establishing stroke wards in all hospitals; (2) continuous training in stroke treatment; (3) telemedicine service staffed by a 24 h/day 'strokologist' with capability for high-speed videoconferencing and transfer of CT/MRI images. Data were prospectively documented in the databank of the telestroke service, in the Bavarian Stroke Registry and in the controlling departments. In 2003, 4,179 stroke patients were admitted to the regional network hospitals. Between February 2003 and January 2004 a total of 2,182 teleconsultations were conducted. 250 teleconsultations yielded a nonvascular diagnosis. Indicators for stroke management quality improved compared with other hospitals without stroke unit: the frequency of CT/MRI within 3 h was 59% compared to 46%, frequency of speech therapy 36% (21%), and of occupational therapy 38% (12%). Eighty-six (2.1%) of the patients received systemic thrombolysis compared to 10 patients in the preceding year. Mean length of in-hospital stay decreased from 12.4 in 2002 to 9.7 days in 2003. This stroke network concept leads to a substantial improvement of stroke management. Telemedicine contributes to an early etiological assessment and fills the gap of specialized stroke expertise in neurologically underserved areas. Copyright 2005 S. Karger AG, Basel.

Alternative strategies for stroke care: a prospective randomised controlled trial.

Benjamin Evans, Christopher Knapp, N. Donaldson … (2000)

Organised specialist care for stroke improves outcome, but the merits of different methods of organisation are in doubt. This study compares the efficacy of stroke unit with stroke team or domiciliary care. A single-blind, randomised, controlled trial was undertaken in 457 acute-stroke patients (average age 76 years, 48% women) randomly assigned to stroke unit, general wards with stroke team support, or domiciliary stroke care, within 72 h of stroke onset. Outcome was assessed at 3, 6, and 12 months. The primary outcome measure was death or institutionalisation at 12 months. Analyses were by intention to treat. 152 patients were allocated to the stroke unit, 152 to stroke team, and 153 to domiciliary stroke care. 51 (34%) patients in the domiciliary group were admitted to hospital after randomisation. Mortality or institutionalisation at 1 year were lower in patients on a stroke unit than for those receiving care from a stroke team (21/152 [14%] vs 45/149 [30%]; p<0.001) or domiciliary care (21/152 [14%] vs 34/144 [24%]; p=0.03), mainly as a result of reduction in mortality. The proportion of patients alive without severe disability at 1 year was also significantly higher on the stroke unit compared with stroke team (129/152 [85%] vs 99/149 [66%]; p<0.001) or domiciliary care (129/152 [85%] vs 102/144 [71%]; p=0.002). These differences were present at 3 and 6 months after stroke. Stroke units are more effective than a specialist stroke team or specialist domiciliary care in reducing mortality, institutionalisation, and dependence after stroke.

Telemedicine for safe and extended use of thrombolysis in stroke: the Telemedic Pilot Project for Integrative Stroke Care (TEMPiS) in Bavaria.

Roman L. Haberl, , C Kukla … (2005)

Systemic thrombolysis represents the only proven therapy for acute ischemic stroke, but safe treatment is reported only in established stroke units. One major goal of the ongoing Telemedic Pilot Project for Integrative Stroke Care (TEMPiS) in Bavaria is to extend the use of tissue plasminogen activator (tPA) treatment in nonurban areas through telemedic support. The stroke centers in Munich-Harlaching and in Regensburg established a telestroke network to provide consultations for 12 local hospitals in eastern Bavaria. The telemedic system consists of a digital network that includes a 2-way video conference system and CT/MRI image transfer with a high-speed data transmission up to 2 Mb/s. Each network hospital established specialized stroke wards in which qualified teams treat acute stroke patients. Physicians in these hospitals are able to contact the stroke centers 24 hours per day. A total of 106 systemic thrombolyses were indicated via teleconsultations between February 1, 2003, and April 7, 2004. During the first 12 months, the rate of thrombolyses was 2.1% of all stroke patients. Mean age was 68 years, and median National Institutes of Health Stroke Scale score was 13. Mean delay between onset and hospital admission was 65 minutes, and door-to-needle time was on average 76 minutes, which included 15 minutes for the teleconsultation. Symptomatic hemorrhage occurred in 8.5% of patients, and in-hospital mortality was 10.4%. The present data suggest that systemic thrombolysis indicated via stroke experts in the setting of teleconsultation exhibits similar complication rates to those reported in the National Institute of Neurological Disorders and Stroke trial. Therefore, tPA treatment is also safe in this context and can be extended to nonurban areas.
