Prehospital delay in acute stroke and TIA

Background Early management improves outcome in acute stroke. This study was designed to assess the prehospital path from symptom onset to arrival in hospital and to identify factors associated with prehospital delay. Methods A prospective study was conducted including patients with acute ischaemic stroke, intracerebral haemorrhage and transient ischaemic attack admitted to hospital. Time intervals for prehospital delay, background data, severity, type of first medical contact and mode of transport were recorded. Univariate and multivariate analyses were performed to identify factors influencing prehospital delay. Results A total of 440 patients were included, with a mean age of 71.4±13.0 years (44.3% female subjects), consisting of 65.9% patients with ischaemic stroke, 11.4% with intracerebral haemorrhage and 22.7% with transient ischaemic attack. The median time from symptom onset to admission was 3.0 h (179 min; IQR 77–542). The median decision delay was 1.5 h (92 min, IQR 25–405) and accounted for 55.1% (median value) of the prehospital delay. 310 (70.5%) patients arrived by ambulance. In the multivariate linear regression analysis, high National Institute of Health Stroke Scale score (p<0.001), transport by ambulance (p<0.001) and lower age (p=0.048) were significantly associated with early admission. Conclusions Severe strokes, use of ambulance and lower age are associated with reduced prehospital delay. The present study shows that more than half of the delay is caused by the hesitation to contact medical services. Public information campaigns should focus on fast symptom recognition and the importance of immediately contacting the Emergency Medical Services upon symptom onset.

Factors Related to Decision Delay in Acute Stroke

BACKGROUND The time from symptom onset to seeking medical assistance (decision delay) accounts for a proportion of prehospital delay in acute stroke. The aims of this study were to identify factors related to decision delay and calling the emergency medical services (EMS) as the first medical contact. METHODS Data were prospectively collected from 350 patients with acute stroke or transient ischemic attack. Data on decision delay, prehospital delay, types of first medical contact, and previous stroke knowledge were recorded. Multivariable logistic regression analyses were conducted to identify factors related to decision delay of 1 hour or less and calling the EMS as the first medical contact. RESULTS The median decision delay was 2.0 hours. Decision delay accounted for 62.3% of prehospital delay (median value). Moderate (National Institutes of Health Stroke Scale [NIHSS] score 8-16; odds ratio [OR] 4.16 [95% confidence interval 1.86-9.30]) or severe symptoms (NIHSS score ≥ 17; OR 10.38 [2.70-39.90]) and living together (OR 1.84 [1.02-3.43]) were associated with decision delay of 1 hour or less. Moderate (OR 6.31 [2.79-14.29]) or severe symptoms (OR 8.44 [2.64-26.98]) were associated with calling the EMS as the first medical contact. Previous stroke knowledge did not affect an early decision or EMS use. CONCLUSIONS The decision to seek medical assistance in acute stroke accounts for more than half of the prehospital delay. Severity of symptoms and living together are related to an early decision (≤1 hour). Previous stroke knowledge does not affect decision delay or EMS use.

Hand hygiene among neurologists attending a congress

Hand hygiene is effective in preventing health care-associated infections, but hand hygiene compliance is low among health care workers in different hospital settings. Less is known about hand hygiene among physicians in a nonhospital setting. We evaluated handwashing behavior among 200 neurologists (100 males and 100 females) attending a world congress. Overall, 74.0% performed proper hand hygiene using soap and water, and there were significant differences between sex and handwashing behavior.

Prehospitalt forløp ved akutt hjerneslag

BACKGROUND Too few patients with acute stroke receive thrombolytic therapy owing to the limited time window for treatment and prehospital delay. The purpose of this study is to describe the prehospital path for patients with acute stroke and, in particular, what distinguishes patients who contact the Emergency Medical Communication Centre (EMCC) from those who contact their general practitioner (GP) or Out-of-hours (OOH) services. MATERIAL AND METHOD Patients with acute cerebral infarction and intracerebral haemorrhage admitted to the Stroke Unit, Department of Neurology, Akershus University Hospital, were included. Data on the prehospital path (prehospital delay, medical contacts) were collected over the period 15 April 2009 – 1 April 2010. RESULTS A total of 299 patients were included in the study. The median age was 75 years and 48.5 % were women. In all, 63.9 % of patients with acute stroke called the EMCC, and 93.7 % of these were taken directly to hospital by ambulance. Of those who called the GP’s office or OOH services, 60.7 % were asked to go to the GP’s office or OOH services in person. Patients who called and attended the GP’s office or OOH services had milder neurological deficits (p < 0.001) and longer patient delay (p = 0.018) than those who called the EMCC. INTERPRETATION Six out of ten patients who contacted the primary health care services were asked to go to the GP’s office/OOH services in person, which resulted in unnecessary delay. The findings from this study may indicate a need for specific training of this group of health care professionals in the prompt handling of patients with possible stroke.

Patient knowledge on stroke risk factors, symptoms and treatment options

Background Public campaigns focus primarily on stroke symptom and risk factor knowledge, but patients who correctly recognize stroke symptoms do not necessarily know the reason for urgent hospitalization. The aim of this study was to explore knowledge on stroke risk factors, symptoms and treatment options among acute stroke and transient ischemic attack patients. Methods This prospective study included patients admitted to the stroke unit at the Department of Neurology, Akershus University Hospital, Norway. Patients with previous cerebrovascular disease, patients receiving thrombolytic treatment and patients who were not able to answer the questions in the questionnaire were excluded. Patients were asked two closed-ended questions: “Do you believe that stroke is a serious disorder?” and “Do you believe that time is of importance for stroke treatment?”. In addition, patients were asked three open-ended questions where they were asked to list as many stroke risk factors, stroke symptoms and stroke treatment options as they could. Results A total of 173 patients were included, of whom 158 (91.3%) confirmed that they regarded stroke as a serious disorder and 148 patients (85.5%) considered time being of importance. In all, 102 patients (59.0%) could not name any treatment option. Forty-one patients (23.7%) named one or more adequate treatment options, and they were younger (p<0.001) and had higher educational level (p<0.001), but had a nonsignificant shorter prehospital delay time (p=0.292). Conclusion The level of stroke treatment knowledge in stroke patients seems to be poor. Public campaigns should probably also focus on information on treatment options, which may contribute to reduce prehospital delay and onset-to-treatment-time.
