RESUMEN
Dizziness is a common leading symptom. Especially patients with chronic vertigo syndromes experience a significant impairment in quality of life up to a limitation of their ability to work in the case of employed persons. The consequences are financial and capacitive burdens on the health system due to frequently multiple examinations and sick leave up to occupational invalidity of the affected patient. In 150 patients with chronic vertigo syndromes and an unclear outpatient diagnosis, at least one diagnosis that justified the complaint was made in over 90% of cases on the basis of a structured interdisciplinary inpatient diagnostic concept. Chronic vertigo syndromes are often multifactorial. Psychosomatic (accompanying) diagnoses were found in more than half of the patients. Targeted therapy can only be recommended after establishing a specific diagnosis. This justifies an interdisciplinary inpatient diagnostic concept for persistently unclear cases.

BACKGROUND AND OBJECTIVE: Telemedical stroke networks improve stroke care and provide access to time-dependent acute stroke treatment in predominantly rural regions. The aim is a presentation of data on its utility and regional distribution. METHODS: The working group on telemedical stroke care of the German Stroke Society performed a survey study among all telestroke networks. RESULTS: Currently, 22 telemedical stroke networks including 43 centers (per network: median 1.5, interquartile range, IQR, 1-3) as well as 225 cooperating hospitals (per network: median 9, IQR 4-17) operate in Germany and contribute to acute stroke care delivery to 48 million people. In 2018, 38,211 teleconsultations (per network: median 1340, IQR 319-2758) were performed. The thrombolysis rate was 14.1% (95% confidence interval 13.6-14.7%) and transfer for thrombectomy was initiated in 7.9% (95% confidence interval 7.5-8.4%) of ischemic stroke patients. Financial reimbursement differs regionally with compensation for telemedical stroke care in only three federal states. CONCLUSION: Telemedical stroke care is utilized in about 1 out of 10 stroke patients in Germany. Telemedical stroke networks achieve similar rates of thrombolysis and transfer for thrombectomy compared with neurological stroke units and contribute to stroke care in rural regions. Standardization of network structures, financial assurance and uniform quality measurements may further strengthen the importance of telestroke networks in the future.

BACKGROUND: Both diagnosis and treatment of neurological emergencies require neurological expertise and are time-sensitive. The lack of fast neurological expertise in regions with underserved infrastructure poses a major barrier for state-of-the-art care of patients with acute neurological diseases and leads to disparity in provision of health care. The main purpose of ANNOTeM (acute neurological care in North East Germany with telemedicine support) is to establish effective and sustainable support structures for evidence based treatments for stroke and other neurological emergencies and to improve outcome for acute neurological diseases in these rural regions. METHODS: A "hub-and-spoke" network structure was implemented connecting three academic neurological centres ("hubs") and rural hospitals ("spokes") caring for neurological emergencies. The network structure includes (1) the establishment of a 24/7 telemedicine consultation service, (2) the implementation of standardized operating procedures (SOPs) in the network hospitals, (3) a multiprofessional training scheme, and (4) a quality management program. Data from three major health insurance companies as well as data from the quality management program are being collected and evaluated. Primary outcome is the composite of first time of receiving paid outpatient nursing care, first time of receiving care in a nursing home, or death within 90 days after hospital admission. DISCUSSION: Beyond stroke only few studies have assessed the effects of telemedically supported networks on diagnosis and outcome of neurological emergencies. ANNOTeM will provide information whether this approach leads to improved outcome. In addition, a health economic analysis will be performed.

BACKGROUND AND PURPOSE: Elevation of cardiac troponin (cTn), a sensitive biomarker of myocardial injury, is frequently observed in severe acute neurological disorders. Case reports suggest that cardiac dysfunction may also occur in patients with transient global amnesia (TGA). Until now, no study has systematically assessed this phenomenon. METHODS: We performed a case-control study using data of consecutive patients presenting with TGA from 2010 to 2015. Multiple logistic regression analysis accounting for age, sex and cardiovascular risk factors was performed to compare the likelihood of myocardial injury [defined as elevation of cTn > 99th percentile (≥14 ng/L); highly sensitive cardiac troponin T assay] in TGA with three reference groups: migraine with aura, vestibular neuritis and transient ischaemic attack (TIA). RESULTS: Cardiac troponin elevation occurred in 28 (25%) of 113 patients with TGA. Patients with TGA with cTn elevation were significantly older, more likely to be female and had higher blood pressure on admission compared with those without. The likelihood of myocardial injury following TGA was at least more than twofold higher compared with all three reference groups [adjusted odds ratio, 5.5; 95% confidence interval (CI), 1.2-26.4, compared with migraine with aura; adjusted odds ratio, 2.2; 95% CI, 1.2-4.4, compared with vestibular neuritis; adjusted odds ratio, 2.3; 95% CI, 1.3-4.2, compared with TIA]. CONCLUSIONS: One out of four patients with TGA had evidence of myocardial injury as assessed by highly sensitive cTn assays. The likelihood of myocardial injury associated with TGA was even higher than in TIA patients with a more pronounced cardiovascular risk profile. Our findings suggest the presence of a TGA-related disturbance of brain-heart interaction that deserves further investigation.

Stroke is one of the most common neurological diseases in acute care. The introduction of new organizational concepts in the rescue chain and in acute inpatient services can significantly reduce time to treatment and patients can receive specific therapeutic options that have been shown to improve acute stroke prognosis. This review provides an overview of organizational structures that lead to improved medical care and outlines the evidence-based therapeutic options. This is intended to give the reader a decision support on provision of specific treatment in acute ischemic stroke. The almost simultaneous proof of effectiveness of mechanical thrombectomy for targeted patient populations in five randomized trials has challenged the organization of stroke care. This provides a good example of how an optimized interplay within the rescue chain from emergency services via community hospitals to referral centers with intervention facilities can ensure access to this novel treatment for as many patients as possible. For the limited time span between onset of symptoms and start of treatment, creative but nevertheless well-standardized concepts have emerged that lead to measurable therapeutic success. It has become an urgent challenge to create sustainable regional infrastructures that allow access to appropriate treatment for all patients.

Mild head injuries are one of the most frequent reasons for attending emergency departments and are particularly challenging in different ways. While clinically important injuries are infrequent, delayed or missed injuries may lead to fatal consequences. The initial mostly inconspicuous appearance may not reflect the degree of intracranial injury and computed tomography (CT) is necessary to rule out covert injuries. Furthermore, infants and young children with a lack of or rudimentary cognitive and language development are challenging, especially for those examiners not familiar with pediatric care. Established check lists of clinical risk factors for children and adults regarding traumatic brain injuries allow specific and rational decision-making for cranial CT imaging. Clinically important intracranial injuries can be reliably detected and unnecessary radiation exposure avoided at the same time.

BACKGROUND: Telemedicine is increasingly used for acute stroke care, making neurological expertise available in nonspecialized hospitals. There are few data about telemedicine's acceptance by either medical staff or patients at treating hospitals. METHODS: Telemedicine's acceptance was evaluated in the Telemedical Project for Integrative Stroke Care (TEMPIS), a network of two stroke centers and 12 community hospitals in the German state of Bavaria; the grading of teleconsultation regarding video and audio quality, time consumption, and medical relevance was assessed in two periods, 2004 and 2007. Overall satisfaction with in-hospital treatment was compared between patients in telemedically-linked hospitals with specialized stroke care and patients treated in conventional community hospitals. With regard to sufficient follow-up rates, ratings were restricted to patients living at home without severe disability at 3 months after stroke. A second evaluation analyzed how the parameter "Telemedical assessment of patient" (36% of patients in TEMPIS hospitals) affected overall satisfaction. RESULTS: Respectively, 140 and 127 uses of telemedicine were assessed in the two evaluation periods. Video quality, time consumption, and medical relevance were graded "excellent" by over 50% in both periods. Audio quality was rated "excellent" by only 22% in the first period but 69% in the second. Excellent overall satisfaction was expressed significantly more frequently by patients at TEMPIS hospitals (total number 1044) than by those at control hospitals (total number 484; 56% vs 47% respectively, P<0.01). Patient consultation via telemedicine per se did not correlate with modified grading. CONCLUSIONS: Acceptance of telemedicine in acute stroke care was high and stable over a long period. This study suggests improved overall satisfaction with treatment in hospitals offering specialized care and linked via telemedicine. Clinical assessment via telemedicine had no major effect on satisfaction.

BACKGROUND: Time to reperfusion treatment is closely related to outcome in ischemic stroke. Prehospital stroke work-up in CT-equipped mobile stroke units is effective in reducing time to thrombolytic treatment. Current evidence predominantly comes from mobile stroke units staffed with neurologists but telemedicine-guided management may be acceptable for providing neurological expertise in ambulances. With unsatisfactory experiences in third-generation (3G)-based approaches, fourth-generation (4G) networks may provide adequate audio-visual quality but systematic comparisons of technological parameters and decision-making are lacking. METHODS: Trained actors presented stroke symptoms and paramedics assisted the remotely guided extended National Institutes of Health Stroke Scale (eNIHSS) assessment on the mobile stroke unit in Berlin, Germany. We compared technical parameters of 4G and 3G connections, assessed audio-visual quality of examination, and analyzed reliability of neurological assessment and treatment decisions made by the remote neurologist versus the mobile stroke unit neurologist. RESULTS: 4G and 3G connections were evaluated in 40 scenarios each. Connectivity was not available in 17% of 4G- and 15% of 3G-attempts with 6% simultaneous unavailability of both networks. The remote examiners graded audio and video quality in 4G better than in 3G with slightly shorter assessment duration in 4G (mean: 9 (SD:5) vs. mean 11 (SD:3) min, p = 0.10). Reliability of the eNIHSS sum scores was high with intraclass correlation coefficients of 0.99 (95% CI: 0.987-1.00) for 4G and 0.98 (95% CI: 0.96-0.99) for 3G. None of the remote treatment decisions differed from onsite decisions. CONCLUSIONS: 4G mobile communications provided higher quality of video-examination and allowed reliable remote assessment of stroke symptoms but coverage was still incomplete in both networks.

The effectiveness of thrombolysis or mechanical recanalization for acute stroke is higher, the sooner these therapies are started. Therefore, acute stroke patients need to be evaluated by qualified staff for these therapies as soon as possible. Lay persons need to identify the typical symptoms of stroke as an emergency and act accordingly by calling the emergency medical system (EMS). The EMS team reassesses the symptoms and prompts cerebral imaging. Cerebral imaging is performed ideally in hospitals with a stroke unit where subsequent (stroke) treatments occur. On the way, the emergency team will measure and stabilize vital functions and obtain further important clinical information. Telemedicine allows communicating exact time of onset and severity of symptoms, as well as comorbidities and medication of the patient to the respective hospital. Thereby, the intrahospital workload will be disencumbered and accelerated. Some EMS vehicles now carry point-of-care laboratories and may measure lab values en route (glucose and INR [International Normalized Ratio] for example). Some ambulances are not only equipped with qualified staff, telemedicine technique, and point-of-care labs but even computer tomography (CT) to perform imaging. Such mobile stroke emergency mobiles (STEMO) or mobile stroke units may perform thrombolysis prehospitally. Prehospital thrombolysis has been proven to be initiated faster and is safe. Preliminary results even suggest superiority to intrahospital thrombolysis with respect to clinical outcome. Moreover, STEMO may perform CT-angiography and assess intracranial large-vessel status. If intracranial large-vessel occlusion is present, patients will be brought directly to hospitals able to perform mechanical recanalization. Thus, secondary transports are no longer required.

PURPOSE: To reduce the time from symptom onset to treatment with tissue plasminogen activator (tPA) in ischemic stroke, an ambulance was equipped with a CT scanner. We analyzed process and image quality of CT scanning during the pilot study regarding image quality and safety issues. MATERIALS AND METHODS: The pilot study of a stroke emergency mobile unit (STEMO) ran over a period of 12 weeks on 5 weekdays from 7a.m. to 6:30 p.m. A teleradiological service for the justifying indication and reporting was established. The radiographer was responsible for the performance of the CT scan on the ambulance. 64 cranial CT scans and 1 intracranial CT angiography were performed. We compared times from ambulance alarm to treatment decision (time of last brain scan) with a cohort of 50 consecutive tPA treatments before implementation of STEMO. RESULTS: 62 (95%) of the 65 scans performed had sufficient quality for reading. Technical quality was not optimal in 45 cases (69%) mainly caused by suboptimal positioning of patient or eye lens protection. Motion artefacts were observed in 8 exams (12%). No safety issues occurred for team or patients. 23 patients were treated with thrombolysis. Time from alarm to last CT scan was 18 minutes shorter than in the tPA cohort before STEMO implementation. CONCLUSION: A teleradiological support for primary stroke imaging by CT on-site is feasible, quality-wise of diagnostic value and has not raised safety issues.

OBJECTIVE: Stroke symptoms in right hemispheric stroke tend to be underestimated in clinical assessment scales, resulting in greater infarct volumes in right as compared to left hemispheric strokes despite similar clinical stroke severity. We hypothesized that patients with right hemispheric nonlacunar stroke are at higher risk for secondary intracerebral hemorrhage after thrombolysis despite similar stroke severity. METHODS: We analyzed data of 2 stroke cohorts with CT-based and MRI-based imaging before thrombolysis. Initial stroke severity was measured with the NIH Stroke Scale (NIHSS). Lacunar strokes were excluded through either the presence of cortical symptoms (CT cohort) or restriction to patients with prestroke diffusion-weighted imaging (DWI) lesion size >3.75 mL (MRI cohort). Probabilities of having a parenchymal hematoma were determined using multivariate logistic regression. RESULTS: A total of 392 patients in the CT cohort and 400 patients in the MRI cohort were evaluated. Although NIHSS scores were similar in strokes of both hemispheres (median NIHSS: CT: 15 vs 13, MRI: 14 vs 16), the frequencies of parenchymal hematoma were higher in right hemispheric compared to left hemispheric strokes (CT: 12.4% vs 5.7%, MRI: 10.4% vs 6.8%). After adjustment for potential confounders (but not pretreatment lesion volume), the probability of parenchymal hematoma was higher in right hemispheric nonlacunar strokes (CT: odds ratio [OR] 2.3; 95% confidence interval [CI] 1.08-4.89; p = 0.032) and showed a borderline significant effect in the MRI cohort (OR 2.1; 95% CI 0.98-4.49; p = 0.057). Adjustment for pretreatment DWI lesion size eliminated hemispheric differences in hemorrhage risk. CONCLUSIONS: Higher hemorrhage rates in right hemispheric nonlacunar strokes despite similar stroke severity may be caused by clinical underestimation of the proportion of tissue at bleeding risk.

BACKGROUND: IV thrombolysis represents the most effective acute stroke therapy. However, it is almost exclusively performed in stroke centers and is not available in most community areas. The Telemedical Pilot Project for Integrative Stroke Care (TEMPiS) was started in February 2003. Twelve community hospitals with no or very limited stroke thrombolysis experience and two stroke centers were connected via a network providing online neurologic examination and transfer of neuroradiologic scans. Following recently published preliminary results on acute phase safety of telethrombolysis, the present study reports on its long-term functional outcome. METHODS: Modified Rankin Scale (mRS), Barthel Index (BI), and mortality rate were prospectively collected 3 and 6 months after IV thrombolysis in patients of community network hospitals (telemedical group) and the stroke centers. Values of 95/100 for the BI and 0/1 for the mRS were defined as a favorable outcome. RESULTS: Over the first 22 months, 170 patients were treated with tPA in the telemedical hospitals and 132 in the stroke center hospitals. Mortality rates were 11.2% vs 11.5% at 3 months (p = 0.55) and 14.2% vs 13% at 6 months (p = 0.45). A good functional outcome after 6 months was found in 39.5% of the telemedical hospitals vs 30.9% of the stroke centers (p = 0.10) for the mRS and 47.1% vs 44.8% (p = 0.44) regarding the BI. CONCLUSIONS: Mortality rates and functional outcomes for telemedicine-linked community hospitals and stroke centers were similar and comparable to the results from randomized trials.

BACKGROUND: Although treatment in a stroke unit has been proven to be effective, most stroke patients in rural areas have no access to it. The community hospital of Ebersberg (Bavaria/Germany) joined the Telemedic Project for Integrative Stroke Care (TEMPiS) in order to optimize the quality of stroke care. This analysis focuses on changes in stroke management using generally accepted indicators for quality of acute stroke treatment. METHODS: The core elements consisted of the setting up of a stroke ward in the community hospital, continual stroke education and a 24-hour telemedical consultation service offered by stroke centers. Treatment of stroke patients was documented during two 12-months periods before the project was started start (i.e. retrospectively) and during the course of the project (prospectively). In addition, data on fatal outcome and institutionalization of patients who had lived at home before the qualifying event were collected 12 months after stroke onset. RESULTS: There were 299 admissions for stroke or transient ischemic attacks between 1 Nov 2001 and 31 Oct 2002, and 305 between 7 July 2003 and 6 June 2004. Length of in-hospital stay decreased from 12.1 to 9.2 days. More patients (10.3 vs. 1.3%) were transferred to other acute hospitals during the later period. Indicators for stroke care quality improved: numbers of cerebral imaging rose from 56.5% to 96.4%, of duplex sonography of cervical arteries from 43.5 to 72.8 %, of speech therapy from 0% to 50.8% and of occupational therapy from 0 to 33.4%. One year after admission, 18.9% and 17.2%, respectively, of the patients had died, while 10.2% and 6.1% were living in institutions. CONCLUSION: Participation in the TEMPiS network substantially improved stroke care quality according to national and international guidelines. These improvements may lead to a better prognosis after a stroke.

BACKGROUND: The benefit of tissue plasminogen activator (t-PA) is strongly associated with the time to treatment. In Bavaria, Germany, only half of the population has the opportunity to be transferred to 1 of the 19 stroke units within the critical time window of less than 3 hours. The aim of this study was to investigate the benefit of a new stroke-code-box for t-PA thrombolysis combined with a telemedicine network system to increase the use of acute stroke thrombolysis. METHODS: Two specialized stroke centers in Germany established a 24-hour telemedicine network (Telemedicine Pilot Project of an Integrated Stroke Care [TEMPiS]) to advise 12 community hospitals in eastern Bavaria. These clinics are linked via telemedicine in a 24-hour/7-day service network that allows patients to be examined by experts via a videoconference system Additionally, a special stroke-code-box for acute t-PA thrombolysis was designed to reduce time in the application and documentation process. RESULTS: In the 12-month period before implementation of the TEMPiS network system, 10 patients had received systemic thrombolysis. In our 6-month study period (from July to December 2003) and after implementation of a stroke-code-box for t-PA thrombolysis within the telestroke network, 164 patients with acute stroke were presented with t-PA treatment indications. Of this patient population, 27.4% (45 of 164) received t-PA. CONCLUSIONS: Stroke care, including t-PA thrombolysis in non-urban areas, is feasible using a modern stroke unit concept within a telestroke network. With the expertise of specialized stroke centers accessed via telemedicine and the design of a stroke-code-box for t-PA thrombolysis, nearly one-third of patients presented with a possible indication for systemic thrombolysis can be treated with t-PA, thereby increasing the options for a successful stroke treatment.

BACKGROUND: Specific stroke subtypes like subarachnoid hemorrhages or malignant brain infarcts require immediate interventions, but treatment options are offered mainly in specialized centers. For this reason, interhospital transfers from primary hospitals need to be done without delay. METHODS: The telemedic pilot project for integrative stroke care (TEMPiS) connects 2 stroke centers and 12 regional hospitals in Bavaria (Germany). Core elements are the implementation of stroke wards, telemedic consultation and improvement of emergency interhospital transfers. Organization of patient transports is offered by the central telemedic service. During the first 12 months of the continuing project all interhospital transfers initiated by the central telemedic service were prospectively documented. Emergency transports were analysed according to diagnosis, type of transport, distance and time delays. RESULTS: A total of 252 interhospital transfers were recommended in teleconsultations; finally 221 transports took place. Median total duration of transfers (including the necessary arrangements) was 134 min (interquartile range: 105-219) for intracerebral hemorrhages (N = 58), 138 min (95-157) for subarachnoid hemorrhages (N = 31), 161 min (100-230) for malignant infarcts (N = 22) and 147 min (109-180) for suspected basilar artery occlusion (N = 28). Time from admission in the primary hospital to initiation of interhospital transfer was 135 min (median; interquartile range: 86-172), transport time was 81 min (60-116). Helicopter transport did not save time for transfer distances up to 50 kilometres, compared to transport via ambulance (including assistance of hospital physicians). Transport using a special intensive care vehicle was much more time consuming because of the longer transport preparation time. CONCLUSION: Emergency transfers of stroke patients are time consuming. This may contribute to additional harm being done to severely ill patients. Faster organization and conduct of transports is required.

More than 100 stroke units have been established in Germany. In rural areas, however, acute stroke care needs to be improved. In order to advance clinical stroke therapy, two specialized stroke centers founded a telemedicine network (TEMPiS) among 12 community hospitals in eastern Bavaria. Each network hospital established specialized stroke wards where qualified teams manage acute stroke patients. Twenty-four hours daily, physicians in local hospitals are able to contact the stroke centers via videoconferencing including transmission of digital DICOM data. To study the efficacy of this network, a controlled trial will be performed. Five TEMPiS-network hospitals will be matched with five other hospitals equal in size, catchment area, and diagnostic techniques. For about 1 year, all consecutive stroke cases in the matched study hospitals will be prospectively recorded in a database. Neurological deficits will be quantified on the National Institute of Health Stroke Scale within 24 h after stroke onset. Mortality and institutional care as a combined primary endpoint will be assessed after 3 and 12 months. Furthermore, functional outcome according to the modified Rankin scale, Barthel score, and quality of life will be assessed using a standard telephone interview. Data acquisition started in July 2003, and final results are expected in 2005.
