Door to Needle Count Down: A 3-Years Experience in an Egyptian University Stroke Center.

BACKGROUND: The purpose of this study is to share our experience in changing hospital strategies to achieve rapid thrombolysis in acute ischemic stroke (AIS) patients in 2 university stroke centers. Rapid reperfusion by shortening door to needle time (DTN) reduces morbidity and mortality for patients with AIS. Our aim is to evaluate the effect of applying certain logistic strategies to reduce DTN for thrombolysis and its impact on clinical outcome. METHODS: In this retrospective registry-based observational study from the SITS-ISTR Dataset, we studied AIS patients admitted to 2 stroke centers in Ain Shams University over 3 successive years from 2016 till 2018. We analyzed change of DTN and outcome at 3 months by modified Rankin scale over these 3 years. RESULTS: By the end of the 3 year period there was a 6.1% increase in number of patients receiving thrombolysis. There was a significant decrease of median DTN by 41%, and increase in percentage of patients receiving recombinant tissue plasminogen activator within a shorter DTN. Also, the number of patients with a favorable outcome (modified Rankin scale≤2) increased by 23.3%. There was insignificant difference regarding mortality rate. CONCLUSION: Applying a goal-directed corrective strategy to improve quality of service can, in a short time, reduce DTN and improve patient outcome.

Pre-hospital causes for delayed arrival in acute ischemic stroke before and during the COVID-19 pandemic: A study at two stroke centers in Egypt.

BACKGROUND: In the current study we investigated the causes of pre-hospital delay as this can compromise the patient's chance to receive thrombolytic therapy and thus impact stroke outcome. METHODS: We surveyed 254 patients regarding reasons for delayed and early arrival to hospital after acute ischemic stroke. The survey was performed over five months, spanning a period pre- and during COVID-19 (between December 7, 2019 and May 10, 2020). RESULTS: A total of 71.2% of patients arrived beyond four hours of onset of ischemic stroke. The commonest cause for delay pre-Covid-19 was receiving treatment in a non-stroke hospital, while that during COVID-19 was fear of infection and lock down issues. Not realizing the urgency of the condition and stroke during sleep were common in both periods. Early arrival because of the patient's previous experience with stroke accounted for approximately 25% of cases in both periods. The effect of media was more evident during COVID-19, accounting for 47.7% of cases. CONCLUSION: Pre-hospital delay secondary to misperception of the urgency of stroke and management in a non-stroke hospital reflect the lack of awareness among the public and medical staff. This concept is emphasized by early arrival secondary to previous experience with stroke and the pronounced effect of media in the time of COVID-19.

Borderzone Infarction and Small Vessel Disease in a Sample of Egyptian Stroke Patients: Differences and Similarities.

BACKGROUND: The anatomical location of white matter hyperintense lesions in small vessel disease are apparently similar to those of borderzone infarction. The objective of this study is to find clinical and radiological points of differentiation between the two vascular disorders in a sample of Egyptian patients which might have an impact on primary and secondary prevention. METHODS: Ischemic stroke patients with white matter lesions were categorized into two groups: small vessel disease and borderzone infarctions. NIHSS was done on admission. Risk factor profile was reported, and investigations done including: HbA1C, lipid profile, CRP, ECG, echocardiography, carotid duplex, brain MRI, MRA and MR perfusion study. RESULTS: 46 patients completed the study, 29 with SVD and 17 with BZI. Smoking, hypertension and recurrent stroke were more common in borderzone infarctions, but only diabetes was significantly higher (p = 0.047). Limb shaking was more observed in borderzone infarctions (p = 0.049). Radiologically: lacunar pattern was observed more in small vessel disease, while rosary pattern was more in borderzone infarctions (p = 0.04). FLAIR symmetrical lesions and microbleeds were more significant in small vessel disease (p = <0.001; 0.048, respectively). Perfusion study time to peak denoted evidence of significant hypoperfusion in all regions of interest in borderzone infarctions. CONCLUSION: Limb shaking, retinal claudication or syncope, with MRI showing rosary pattern of white matter hyperintensity, few microbleeds and markedly impaired perfusion favor the diagnosis of borderzone infarctions. On the other hand, presence of lacunae, FLAIR showing symmetrical WMH and microbleeds with minimal or no perfusion deficit suggests the diagnosis of small vessel disease.

Factors related to time of stroke onset versus time of hospital arrival: A SITS registry-based study in an Egyptian stroke center.

BACKGROUND: High-quality data on time of stroke onset and time of hospital arrival is required for proper evaluation of points of delay that might hinder access to medical care after the onset of stroke symptoms. PURPOSE: Based on (SITS Dataset) in Egyptian stroke patients, we aimed to explore factors related to time of onset versus time of hospital arrival for acute ischemic stroke (AIS). MATERIAL AND METHODS: We included 1,450 AIS patients from two stroke centers of Ain Shams University, Cairo, Egypt. We divided the day to four quarters and evaluated relationship between different factors and time of stroke onset and time of hospital arrival. The factors included: age, sex, duration from stroke onset to hospital arrival, type of management, type of stroke (TOAST classification), National Institute of Health Stroke Scale (NIHSS) on admission and favorable outcome modified Rankin Scale (mRS ≤2). RESULTS: Pre-hospital: highest stroke incidence was in the first and fourth quarters. There was no significant difference in the mean age, sex, type of stroke in relation to time of onset. NIHSS was significantly less in onset in third quarter of the day. Percentage of patients who received thrombolytic therapy was higher with onset in the first 2 quarters of the day (p = <0.001). In-hospital: there was no difference in percentage of patients who received thrombolytic therapy nor in outcome across 4 quarters of arrival to hospital. CONCLUSION: Pre-hospital factors still need adjustment to improve percentage of thrombolysis, while in-hospital factors showed consistent performance.

Urban Versus Rural Egypt: Stroke Risk Factors and Clinical Profile: Cross-Sectional Observational Study.

BACKGROUND: Egypt is a densely populated country with living habits and health care services that differ from urban to rural regions. We aimed to study how characteristics of stroke vary among these regions. METHODS: This is a cross-sectional observational study of ischemic stroke, thus hemorrhagic and venous strokes were excluded. A total of 1475 ischemic stroke patients were recruited for analysis from a tertiary hospital in Cairo representing urban area and from a secondary care hospital in Suhag representing rural region. RESULTS: Analysis was done for 1143 ischemic stroke patients from urban and 332 from rural area. Onset to door was shorter in urban. Urban patients showed an older age and higher prevalence of hypertension and diabetes (65.9%, 48.6% respectively), while rural patients were characterized by female preponderance (51.5%), more dyslipidemia, smoking 44.6%, stroke in young 20.5%, atrial fibrillation 23.8% % and recurrent stroke 44.3%. Rural cases showed a severer deficit at onset and poorer outcome. CONCLUSION: Vascular risk factors, stroke type, and presentation tend to differ in Egypt according to the geographic distribution whether urban or rural. Studying patterns of such difference may aid in planning specific targeted preventive and therapeutic strategies for stroke in urban and rural Egypt.
