Time Frame for Hospitalization and Inpatient Stroke Workup After Stroke-Like Symptoms

Risk Stratification Based on Time from Symptom Onset

• Patients with stroke-like symptoms should be hospitalized and receive inpatient stroke workup immediately if presenting within 24 hours of symptom onset, with highest priority for those presenting within 4.5 hours when thrombolytic therapy may be administered, as recommended by the International Journal of Stroke 1, 2
• Patients with transient, fluctuating, or persistent unilateral weakness, language/speech disturbance, or other symptoms suggestive of stroke within the past 48 hours should be immediately sent to an emergency department with capacity for advanced stroke care, according to the International Journal of Stroke 1
• Urgent brain imaging and non-invasive vascular imaging should be completed as soon as possible within 24 hours, as suggested by the International Journal of Stroke 1
• Patients presenting with symptoms of unilateral weakness or language/speech disturbance should receive comprehensive clinical evaluation and investigations by a healthcare professional with stroke expertise as soon as possible, ideally within 24 hours of first contact with the healthcare system, as recommended by the International Journal of Stroke 1
• Patients presenting between 48 hours and 2 weeks with symptoms without unilateral motor weakness or language/speech disturbance should receive comprehensive evaluation ideally within two weeks, according to the International Journal of Stroke 1
• Patients presenting more than 2 weeks following suspected TIA or non-disabling stroke should be seen by a neurologist or stroke specialist ideally within one month, as suggested by the International Journal of Stroke 1

Critical Time Windows for Acute Treatment

• The "golden hour" for stroke treatment is within the first 3 hours when thrombolytic therapy has the highest efficacy and safety profile, as stated by the American Heart Association, although the citation is from Praxis Medical Insights 2
• Intravenous thrombolytic therapy can be administered up to 4.5 hours from stroke symptom onset, according to the American Heart Association guidelines, although the citation is from Praxis Medical Insights 2
• Endovascular treatment may be considered for highly selected patients up to 24 hours from symptom onset based on neurovascular imaging, as recommended by the American Heart Association, although the citation is from Praxis Medical Insights 2

Recommendations for Optimal Stroke Care

• All patients admitted to hospital with acute stroke should be treated on an inpatient stroke unit as soon as possible, ideally within 6 hours of hospital arrival, as recommended by the International Journal of Stroke and the American Heart Association 4
• For patients with their first TIA within the past 24-48 hours, hospitalization should be considered to facilitate possible early intervention if symptoms recur, according to the Annals of Neurology and the American Heart Association 3
• Multiple and increasingly frequent symptoms justify hospitalization rather than expedited ambulatory management, as suggested by the Annals of Neurology and the American Heart Association 3
• Hospitals and general practitioners should agree on local protocols for referral to specialist assessment clinics for patients with TIA who don't require hospital admission, according to the Annals of Neurology and the American Heart Association 3
• Failing to recognize in-hospital strokes promptly can lead to worse outcomes compared to community-onset strokes, as stated by the International Journal of Stroke and the American Heart Association 4
• Waiting for symptoms to resolve spontaneously rather than seeking immediate medical attention reduces the chance of receiving time-sensitive treatments, as recommended by the American Heart Association, although the citation is from Praxis Medical Insights 2
