Presenting symptoms and onset-to-arrival time in patients with acute stroke and transient ischemic attack.
Delayed arrival to the emergency department (ED) precludes most stroke patients from receiving thrombolytic treatment. Our objective in this study was to examine the association between presenting symptoms and onset-to-arrival time (ie, time between onset of symptoms to arrival at the ED) in a statewide stroke registry. Demographics, clinical data, and presenting symptoms were collected for patients with acute stroke or symptomatic transient ischemic attack (TIA) admitted to 15 Michigan hospitals (n = 1922). ⋯ Difficulty with walking, balance, or dizziness (12%), confusion (9%), loss of consciousness (6.7%) and falls (3.4%) were associated with lower likelihood of arriving within 2 hours (walking: aOR, 0.7; 95% CI, 0.4-1.0; confusion: aOR, 0.5; 95% CI, 0.3-0.8; consciousness: aOR, 0.5; 95% CI, 0.1-0.9; falls: aOR, 0.4; 95% CI, 0.3-0.9). Presenting symptoms were strongly associated with time of arrival; patients with unilateral symptoms and speech difficulties were more likely to seek care early. Future studies should consider including more specific patient-level data to identify psychosocial and behavioral aspects of recognition and action to stroke symptoms.

Case ReportsIntravenous thrombolysis in an elderly patient with acute ischemic stroke masking aortic dissection.
Before thrombolytic treatment for acute ischemic stroke is undertaken, conditions associated with increased risk of hemorrhagic complications, such as an acute aortic dissection (AAD), should be excluded. We report an 80-year-old woman with acute ischemic stroke as the sole clinical manifestation of AAD who was treated with intravenous (IV) tissue plasminogen activator (tPA). She had no history of hypertension or any signs or symptoms suggestive of AAD. ⋯ Infusion of tPA was stopped, and subsequent computed tomography angiography confirmed Stanford type A aortic dissection. In this case, prompt neurosonologic evaluation helped us make an appropriate diagnosis and avoid complications related to treatment. Neurosonologic evaluation should be considered as soon as possible in all patients with acute ischemic stroke, especially when thrombolytic treatment is being considered.

Factors associated with misdiagnosis of acute stroke in young adults.
Misdiagnosis or delayed diagnosis of acute ischemic stroke can result in neurologic worsening or a missed opportunity for thrombolysis. Because stroke in young adults is less common than stroke in the elderly, we sought to determine clinical characteristics associated with misdiagnosis of stroke in young adults. Patients from the prospectively maintained Young Stroke Registry in our comprehensive stroke center were reviewed. ⋯ Patients presenting with vertebrobasilar territory ischemia have a greater rate of misdiagnosis. Our study demonstrates the increasing need for "young stroke awareness" among emergency department personnel. Initial misdiagnosis can potentially lead to a lost opportunity for thrombolysis in otherwise good candidates.

Reliability and validity of COOP/WONCA functional health status charts for stroke patients in primary care.
Dartmouth Coop Functional Health Assessment/World Organization of National Colleges, Academies and Academic Association of General Practitioners (COOP/WONCA) functional health assessment charts depict levels of function/well being along 5-point ordinal scales in 6 domains. Responses, illustrated by drawings, make these charts a suitable tool for the stroke population, given the high prevalence (20%) of language impairment in this population. This study examined the validity and reliability of COOP/WONCA charts for community-dwelling stroke survivors. ⋯ Discriminative ability for independent ambulation and clinical depression was demonstrated (U = 103.5, P < .001; U = 156, P = .015). Test-retest reliability in each domain except Changes in Health was significant at P < .05 (Kendall's τ-b, 0.344-0.653). Our data indicate that the COOP/WONCA Functional Health charts demonstrate good validity and overall reliability for use with stroke patients in primary care.

Multicenter StudyFactors influencing cooperation among healthcare providers in a community-based stroke care system in Japan.
Community-based stroke care in Japan is currently provided in acute hospitals, convalescent rehabilitation units, general practices, sanatorium-type wards, nursing care facilities, and in-home/commuting care services. We conducted a nationwide survey to identify factors influencing cooperation among the various providers of community-based stroke care. We sent questionnaires to 11,178 facilities and assessed the independent variables of excellent and fair cooperation among the care providers. ⋯ The following independent variables were inversely associated with excellent or fair cooperation in the community: area with the higher population density among 3 groups divided by tertile threshold (odds ratio [OR], 0.53; 95% confidence interval [CI], 0.41-0.69), facilities covered by long-term care insurance (OR, 0.27; 95% CI, 0.22-0.34), and insufficient communication with local government (OR, 0.19; 95% CI, 0.14-0.24). Positive independent variables of excellent or fair cooperation were the sharing of patient information in the community (OR, 2.53; 95% CI, 1.78-3.66), use of a scale for assessing activities of daily living (OR, 1.93; 95% CI, 1.42-2.63), appropriate utilization of care support managers (OR, 1.91; 95% CI, 1.43-2.55), and adequate comprehension of the long-term care insurance system (OR, 1.54; 95% CI, 1.24-1.92). Our findings suggest that improved communication between healthcare providers and local government, along with appropriate attention to the problems facing providers covered by long-term care insurance, may improve community-based stroke care in Japan.
