Background and Purpose—
The increasing demand and shortage of experts to evaluate and treat acute stroke patients has led to the development of remote communication tools to aid stroke management. We aimed to evaluate the JOIN App smartphone system—a low-cost tool for rapid clinical and neuroimaging data sharing to expedite decision-making in stroke.
Methods—
Consecutive acute ischemic stroke patients treated at a University Hospital in Brazil from December 2014 to December 2015 were evaluated. The analysis included all patients presenting with acute ischemic stroke who underwent initial evaluation by neurology residents followed by JOIN teleconsultation with a stroke neurologist on call for management decisions. An expert panel of stroke neurologists and neuroradiologists revised all cases using a standard Picture Archiving and Communication System imaging workstation within 24 hours and analyzed the decision made with remote assistance during the emergency setting.
Results—
A total of 720 stroke codes were evaluated with 442 acute ischemic stroke qualifying. Seventy-eight (18%) patients were treated with intravenous thrombolysis. The main reasons for tPA (tissue-type plasminogen activator) exclusion were symptom onset >4.5 hours (n=295; 67%) and hypodense middle cerebral artery territory area >1/3 (n=31; 7%). The agreement rates between Picture Archiving and Communication System versus JOIN-based thrombolysis decisions were 100% for the stroke (unblinded) and 99.3% for the neuroradiologist (blinded) experts. The use of the application resulted in a significant reduction in the door-to-needle times across the pre- versus postimplementation periods (median, 90 [interquartile range, 75–106] versus 63 [interquartile range, 61–117] minutes;
P
=0.03). The rates of 90-day excellent outcomes (modified Rankin Scale, 0–1) were 51.3%; 90-day mortality, 2.6%; and symptomatic intracranial hemorrhage, 3.8%.
Conclusions—
The JOIN smartphone system allows rapid sharing of clinical and imaging data to facilitate decisions for stroke treatment. The remote application-based decisions seem to be as accurate as the physical presence of stroke experts and might lead to faster times to treatment. This system represents an easily implementable low-cost telemedicine solution for centers that cannot afford the full-time presence of stroke specialists.
Background: The effect of early mobilization after acute stroke is still unclear, although some studies have suggested improvement in outcomes. We conducted a randomized, single-blind, controlled trial seeking to evaluate the feasibility, safety, and benefit of early mobilization for patients with acute ischemic stroke treated in a public teaching hospital in Southern Brazil. This report presents the feasibility and safety findings for the pilot phase of this trial. Methods: The primary outcomes were time to first mobilization, total duration of mobilization, complications during early mobilization, falls within 3 months, mortality within 3 months, and medical complications of immobility. We included adult patients with CT- or MRI-confirmed ischemic stroke within 48 h of symptom onset who were admitted from March to November 2012 to the acute vascular unit or general emergency unit of a large urban emergency department (ED) at the Hospital de Clínicas de Porto Alegre. The severity of the neurological deficit on admission was assessed by the National Institutes of Health Stroke Scale (NIHSS). The NIHSS and modified Rankin Scale (mRS, functional outcome) scores were assessed on day 14 or at discharge as well as at 3 months. Activities of daily living (ADL) were measured with the modified Barthel Index (mBI) at 3 months. Results: Thirty-seven patients (mean age 65 years, mean NIHSS score 11) were randomly allocated to an intervention group (IG) or a control group (CG). The IG received earlier (p = 0.001) and more frequent (p < 0.0001) mobilization than the CG. Of the 19 patients in the CG, only 5 (26%) underwent a physical therapy program during hospitalization. No complications (symptomatic hypotension or worsening of neurological symptoms) were observed in association with early mobilization. The rates of complications of immobility (pneumonia, pulmonary embolism, and deep vein thrombosis) and mortality were similar in the two groups. No statistically significant differences in functional independence, disability, or ADL (mBI ≥85) were observed between the groups at the 3-month follow-up. Conclusions: This pilot trial conducted at a public hospital in Brazil suggests that early mobilization after acute ischemic stroke is safe and feasible. Despite some challenges and limitations, early mobilization was successfully implemented, even in the setting of a large, complex ED, and without complications. Patients from the IG were mobilized much earlier than controls receiving the standard care provided in most Brazilian hospitals.
= 1.03; 95% CI = 1.01-1.06; p = 0.011), higher NIHSS (OR = 1.08; 95% CI = 1.03-1.14; p = 0.001), hemorrhagic transformation (OR = 2.33; 95% CI = 1.11-4.76; p = 0.024), seizures (OR = 3.07; 95% CI = 1.22-7.75; p = 0.018) and large cortical area (ASPECTS ≤ 7) (OR = 2.04; 95% CI = 1.04-3.84; p = 0.036). Concluding, in this retrospective cohort study, the neurological impairment after thrombolysis (but not before) and hemorrhagic transformation remained independent risk factors for seizures or post-stroke epilepsy after thrombolysis. Moreover, we observed that seizures emerged as an independent risk factor for poor outcome after thrombolysis therapy in stroke patients (OR = 3.07; 95% CI = 1.22-7.75; p = 0.018).
Background: Decompressive hemicraniectomy (DHC) is a life-saving procedure for treatment of large malignant middle cerebral artery (MCA) strokes. Post-stroke epilepsy is an additional burden for these patients, but its incidence and the risk factors for its development have been poorly investigated. Objective: To report the prevalence and risk factors for post-stroke seizures and post-stroke epilepsy after DHC for treatment of large malignant MCA strokes in a cohort of 36 patients. Methods: In a retrospective cohort study of 36 patients we report the timing and incidence of post-stroke epilepsy. We analyzed if age, sex, vascular risk factors, side of ischemia, reperfusion therapy, stroke etiology, extension of stroke, hemorrhagic transformation, ECASS scores, National Institutes of Health Stroke Scale (NIHSS) scores, or modified Rankin scores were risk factors for seizure or epilepsy after DHC for treatment of large MCA strokes. Results: The mean patient follow-up time was 1,086 days (SD = 1,172). Out of 36 patients, 9 (25.0%) died before being discharged. After 1 year, a total of 11 patients (30.6%) had died, but 22 (61.1%) of them had a modified Rankin score ≤4. Thirteen patients (36.1%) developed seizures within the first week after stroke. Seizures occurred in 22 (61.1%) of 36 patients (95% CI = 45.17–77.03%). Out of 34 patients who survived the acute period, 19 (55.9%) developed epilepsy after MCA infarcts and DHC (95% CI = 39.21–72.59%). In this study, no significant differences were observed between the patients who developed seizures or epilepsy and those who remained free of seizures or epilepsy regarding age, sex, side of stroke, presence of the clinical risk factors studied, hemorrhagic transformation, time of craniectomy, and Rankin score after 1 year of stroke. Conclusion: The incidence of seizures and epilepsy after malignant MCA infarcts submitted to DHC might be very high. Seizure might occur precociously in patients who are not submitted to anticonvulsant prophylaxis. The large stroke volume and the large cortical ischemic area seem to be the main risk factors for seizure or epilepsy development in this subtype of stroke.
Background: Emergency department (ED) care for acute vascular diseases faces the challenge of overcrowding. A vascular unit is a specialized, protocol-oriented unit in the ED with a team trained to manage acute vascular disorders, including stroke, coronary syndromes, pulmonary embolism (PE), and aortic diseases.
