What is the purpose of this trial?

OPTIMISTmain is an investigator-initiated and conducted, international, multicentre, stepped wedge cluster randomized controlled trial comparing the effects of different intensities of nursing care monitoring for patients with acute ischemic stroke of mild severity and without critical care needs after IV-tPA.

Do I need to stop my current medications for this trial?

The trial protocol does not specify whether you need to stop taking your current medications. Please consult with the trial coordinators for more details.

What safety data exists for post-stroke monitoring strategies for ischemic stroke?

The provided research does not directly address safety data for specific post-stroke monitoring strategies like 'Guideline recommended standard monitoring,' 'Low-intensity monitoring strategy,' or 'Optimal Post Tpa-Iv Monitoring.' However, the studies emphasize the importance of evidence-based guidelines for secondary prevention and management of ischemic stroke, including antiplatelet therapy and risk factor control. The Liverpool Heart And bRain Project (L-HARP) aims to investigate cardiovascular outcomes and risk factors post-stroke, which may indirectly contribute to understanding safety in monitoring strategies. Further specific studies would be needed to evaluate the safety of these particular monitoring strategies. ^{1 2 3 4 5}

Is the treatment 'Guideline recommended standard monitoring' a promising treatment for post-stroke monitoring in ischemic stroke?

Yes, 'Guideline recommended standard monitoring' is a promising treatment for post-stroke monitoring in ischemic stroke. It helps in preventing future strokes by controlling risk factors and using appropriate therapies. This approach is based on expert recommendations and evidence, aiming to improve patient outcomes. ^{2 6 7 8 9}

What data supports the idea that Post-Stroke Monitoring Strategies for Ischemic Stroke is an effective treatment?

The available research shows that effective management of ischemic stroke involves prompt assessment and monitoring of vital signs like blood pressure and oxygen levels. This helps in early detection of complications and improves patient outcomes. While the research highlights the importance of organized stroke services and early interventions like aspirin and intravenous treatments, it emphasizes that close monitoring is crucial to detect any early signs of deterioration. This supports the idea that Post-Stroke Monitoring Strategies are effective in managing ischemic stroke. ^{10 11 12 13 14}

vital signs (HR, BP) and neurological assessment (GCS and/or NIHSS) 15-30mins x 2 hours, 2hourly x 8 hours, 4hourly x 14 hours in a non-ICU ward

Group II: Guideline recommended standard monitoring Placebo Group 1 Intervention

Published Research Related to This Trial

In a study of 114 patients with ischaemic stroke, brain edema occurred in 7.9% of cases, particularly affecting women, those with hypertension, elevated serum creatinine, and diabetes.

While brain edema did not significantly impact survival rates after acute ischaemic stroke, it was associated with a greater degree of neurological deficits at both admission and discharge.

Acute ischemic stroke, which makes up 80% of all strokes, is a major cause of death and disability, but management strategies have significantly improved over time.

Key advancements in treatment include the establishment of intensive care stroke units, acute recanalization techniques, and better management of post-stroke complications, all aimed at enhancing patient outcomes.

National audits in the UK highlight ongoing deficiencies in basic stroke care, emphasizing the need for prompt assessment and management of key physiological parameters like blood pressure and oxygenation.

Three critical interventions for acute ischaemic stroke—admission to a specialized stroke service, early administration of aspirin, and intravenous thrombolysis—are proven to improve patient outcomes, and implementing multidisciplinary guidelines can enhance overall care quality.

Timely intervention in acute ischaemic stroke is crucial, as the severity of brain injury worsens rapidly in the first few hours, making early stabilization and reperfusion essential.

The main treatment options for restoring blood flow are intravenous tissue plasminogen activator (IV tPA) and endovascular thrombectomy (EVT), both of which require careful monitoring for potential complications during and after the procedures.

In a study of 565 ischemic stroke patients, adherence to current stroke performance measures did not show a significant association with better functional outcomes 90 days post-stroke, as measured by activities of daily living scores.

Despite 58.4% of patients receiving defect-free care and a high median opportunity score, these factors did not correlate with improved recovery, suggesting a need for the development of more effective performance measures for stroke care.

Antiplatelet therapy, particularly with agents like clopidogrel and the combination of aspirin plus dipyridamole, is highly effective for secondary prevention of recurrent vascular events in patients with ischemic stroke or TIA, and is preferred over oral anticoagulants for non-cardioembolic strokes.

Despite strong evidence-based guidelines supporting the use of these therapies, their implementation remains low, highlighting the need for quality improvement initiatives to enhance adherence and improve patient outcomes.

Strokes are classified into ischemic (80-87%) and hemorrhagic (13-20%), with ischemic strokes being caused by blood clots or reduced blood flow, highlighting the importance of rapid assessment and treatment to maximize brain tissue reperfusion.

Effective stroke management focuses on stabilizing the patient and may include thrombolytics if appropriate, while prevention strategies emphasize controlling cardiovascular risk factors and using antiplatelet therapy to reduce the risk of first-time or recurrent strokes.

Detecting atrial fibrillation in patients who have had an ischemic stroke is crucial because it can lead to better secondary stroke prevention through the use of oral anticoagulants, which are more effective than antiplatelet drugs.

The paper proposes a structured approach for ECG monitoring in stroke units to improve the detection of atrial fibrillation, although the optimal duration and method of monitoring are still being determined.

Timely recognition and treatment of acute ischemic stroke is crucial, with intravenous tissue plasminogen activator (t-PA) being the primary treatment for eligible patients, while those who do not qualify should receive aspirin therapy.

All stroke patients should receive supportive care, including hydration, correction of hypoxia, and management of hyperglycemia and fever, with individualized blood pressure management based on their specific condition.

Antiplatelet therapy can reduce the risk of subsequent strokes by 11-15% in patients with ischemic stroke or transient ischemic attack, but its effectiveness varies based on individual platelet reactivity.

Monitoring platelet function is crucial for optimizing antiplatelet therapy, as patients resistant to aspirin may benefit from dual antiplatelet therapy, highlighting the need for personalized treatment strategies.
