• Conditions: High-Risk Stroke Population

• Registration Number: NCT06816238
• Lead Sponsor: Second Affiliated Hospital, School of Medicine, Zhejiang University

Brief Summary

With its high incidence, recurrence, disability, and mortality, stroke has become a significant health challenge in society today. However, "stroke can be prevented and treated," and high-risk groups for stroke are the primary beneficiaries of stroke prevention and control measures. Yet, these populations often have low awareness of proper stroke prevention and treatment knowledge. The reasons for this may include limited coverage, lack of accessibility, inadequate relevance, and uneven content quality in traditional health education measures.

To address these issues, innovative intervention strategies are needed to explore more effective health education methods. The occurrence of Major Adverse Cardiovascular Events (MACE), such as stroke, can be reduced by improving the knowledge and practical abilities of high-risk populations regarding scientific stroke prevention and treatment. One such strategy is the use of smartphone-based information software, which can break the constraints of time and space, delivering health education knowledge to a broader audience. To enhance accessibility, key knowledge points can be repeatedly delivered to the target population through one-way push notifications and interactive Q\&A, allowing for more engaging and flexible learning. In terms of improving pertinence, it is essential to tailor health education delivery to the individual needs of the educatees, considering factors such as age, education level, and risk factors. Furthermore, the quality of health education content must be authoritative, scientifically accurate, easy to understand, and practically applicable. The content should be based on the latest scientific research and professional medical practice, reviewed by authoritative institutions or experts, and should align with the needs of the educated populations for self-health management. Additionally, human and financial costs should be considered when designing such interventions.

In this study, a large-scale medical model based on a stroke prevention and treatment knowledge base, integrated with an intelligent medical system and interactive Q\&A, is employed. This approach ensures content quality while minimizing the need for additional manpower in education and Q\&A, making the intervention more cost-effective and scalable for widespread use. The purpose of this study is to explore whether the incidence of MACE in a high-risk stroke population receiving interactive medical model education-based on a stroke prevention and treatment knowledge base-is lower than in a group without such interactive education.

Detailed Description

With its high incidence, recurrence, disability and mortality, stroke has become an important health challenge facing the society at present. However, "stroke can be prevented and treated," and high-risk groups of stroke are the main beneficiaries of stroke prevention and control and the intervention targets of "health education" measures. Yet, their awareness of correct stroke prevention and treatment knowledge is low. The reasons may be related to the limited coverage, lack of accessibility, lack of pertinence, and uneven content quality of traditional health education measures.

Therefore, we need to adopt innovative intervention strategies to overcome these constraints and explore effective ways of health education. The occurrence of Major Adverse Cardiovascular Events (MACE), such as stroke, can be reduced by improving the knowledge level and practical ability of scientific stroke prevention and treatment in high-risk populations. In this study, the intervention is based on a large medical model using a medical intelligent agent for interactive Q\&A. This approach is designed to enhance popularization, accessibility, pertinence, and content quality.

Popularization: The use of smartphone-based information software can break through the limitations of time and space, conveying health education knowledge to a wider audience.

Accessibility: Key knowledge points can be repeatedly delivered to the target audience through one-way pushes of health education content, complemented by interactive Q\&A with intelligent medical agents.

Pertinence: Health education content is personalized based on the individual's age, education level, risk factors, and other personal characteristics, ensuring relevance to each educatee.

Content Quality: The educational content is authoritative, scientifically accurate, easy to understand, and practical, drawing from the latest scientific research and professional medical practices, reviewed by authoritative experts and institutions. The intervention ensures that the educated's needs for self-health management are fully considered.

This model leverages the large medical knowledge base and intelligent medical agents to provide personalized, scalable, and cost-effective education, which eliminates the need for additional manpower in education and Q\&A. This approach helps reduce costs while enabling large-scale implementation.

The purpose of this study was to explore whether the incidence of MACE in high-risk stroke populations receiving interactive education based on a medical knowledge model and intelligent Q\&A is lower than that in a group without such education.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Primary Outcome Measures

Name	Time	Method
MACE Incidence	1 year from enrollment	The occurrence of major adverse cardiovascular events (MACE), including stroke (ischemic or hemorrhagic), myocardial infarction, heart failure, or cardiovascular death, in participants over the 1-year follow-up period. MACE is a composite outcome that captures the broad range of adverse cardiovascular events.

Secondary Outcome Measures

Name	Time	Method
Adherence to Stroke Prevention Medications	1 year from enrollment	Proportion of participants adhering to prescribed medications (e.g., antihypertensives, antiplatelets) for stroke prevention, measured via self-reports or pharmacy refill data.
Thrombolysis Use in Ischemic Stroke	1 year from enrollment	Proportion of ischemic stroke patients who receive thrombolysis treatment (IV tPA or intra-arterial therapy) within the recommended time window.
Blood Pressure Control	1 year from enrollment	Proportion of participants maintaining blood pressure within recommended levels (e.g., \<140/90 mmHg) as part of stroke and cardiovascular risk management.
Smoking Cessation (for smokers)	1 year from enrollment	Proportion of smokers who quit smoking within 3 months of the intervention, as assessed by self-report and/or biochemical validation (e.g., carbon monoxide levels, cotinine levels).
Physical Function and Quality of Life (QoL)	1 year from enrollment	Assessment of physical function and overall quality of life, measured using standardized scales like the EQ-5D or the SF-36, to understand the impact of the intervention on the participant's daily living and wellbeing.
