🧠 What is Stroke?

A stroke occurs when there is a blockage in the blood vessels that supply blood to the brain, resulting in a decrease in blood flow and oxygen to a specific region. This medical condition can cause severe damage to the brain cells, leading to disabilities and even death. Ischemic stroke, which accounts for 90% of stroke cases, is caused by a clot that obstructs the blood vessels. The Timely and accurate diagnosis and treatment of stroke play a crucial role in preventing long-term disabilities and improving patient outcomes.

🌟 How Does AI Improve Stroke Care?

The introduction of artificial intelligence (AI) in stroke care has revolutionized the way stroke patients are diagnosed and treated. AI-powered systems, such as the one developed by our company, VI, have significantly improved the efficiency and effectiveness of stroke care by streamlining the clinical workflow and providing real-time alerts to physicians. By connecting hospitals to the cloud and analyzing medical imaging data using AI algorithms, stroke care can be expedited, allowing for faster treatment decisions and reducing the time to intervention.

💥 The Impact of AI in Stroke Care

The impact of AI in stroke care is significant, considering the devastating consequences of delayed or inadequate treatment. Stroke is the number three killer in the Western world, and its treatment is one of the most time-sensitive conditions in medicine. Every minute of delay in treatment results in the death of millions of brain cells and leads to longer periods of disability for patients. The use of AI technology has shown promising results in reducing the time to treatment, improving patient outcomes, and ultimately saving lives.

🎯 Research Approaches in Stroke Care

To ensure the efficacy and safety of AI-based stroke care, extensive research and clinical trials are essential. Our company, VI, recognizes the importance of research and has incorporated it into our development process. We have collaborated with renowned hospitals and physicians to conduct pre-post comparison studies, randomized controlled trials, and stepped wedge designs to evaluate the effectiveness of our AI system. These research approaches have provided valuable insights into the impact of AI on stroke care and have contributed to the continuous improvement of our algorithms.

🤖 Understanding the AI Algorithm

The AI algorithm used in our stroke care system is designed to analyze CT angiography scans and identify potential clots in the blood vessels. The process involves segmenting the brain and blood vessels, tracking the vessel tree, and detecting endpoints that indicate the presence of a clot. By combining multiple AI algorithms and data analysis techniques, our system generates a large vessel occlusion (LVO) score, alerting physicians to the need for immediate intervention. Continuous refinement and experimentation with the algorithm allow for ongoing improvements and better patient outcomes.

🚀 Challenges in Healthcare Marketing

Marketing in healthcare, especially for innovative AI-based solutions, comes with its own set of challenges. Convincing potential buyers and healthcare administrators about the effectiveness of AI requires robust clinical evidence and research support. The reliance on clinical studies and research data is crucial for gaining trust and adoption in healthcare settings. Our company recognized the importance of generating clinical evidence early on and invested in various research approaches to demonstrate the impact and efficacy of our AI-powered stroke care system.

⚡ Generating Clinical Evidence

To support our marketing efforts and reimbursement applications, we conducted multiple pre-post comparison studies that showed significant time savings in stroke treatment. These studies, conducted in collaboration with hospitals across the country, demonstrated the effectiveness of our system in reducing the time to treatment and improving patient outcomes. We also explored the possibility of running randomized controlled trials and stepped wedge designs but found that the logistical challenges and costs outweighed the benefits. Ultimately, the publication of these studies and the endorsement of renowned physicians solidified our position in the market.

🎯 The Role of Randomized Controlled Trials

Randomized controlled trials are considered the gold standard for assessing treatment efficacy and establishing causality. While we intended to conduct randomized controlled trials for our AI-based stroke care system, we faced various challenges, including cost, logistics, and implementation. However, we recognize the importance of these trials and encourage young entrepreneurs to plan for them early in their development process. Careful consideration must be given to the randomization process, outcome measures, and potential confounding factors to ensure the reliability and validity of the trial results.

🌟 Stepped Wedge Design in Clinical Trials

In our Quest for an alternative to randomized controlled trials, we explored the stepped wedge design. This design allows for a gradual and randomized implementation of the intervention across multiple hospitals. By comparing the pre-post outcomes in each hospital, we can infer causality while minimizing the impact of external factors. This design also enables us to work closely with hospitals, identify areas of improvement, and optimize the performance of our AI algorithm. The stepped wedge design offers a promising middle ground between pre-post comparison and fully randomized controlled trials.

💡 Continuous Improvement of the Algorithm

The development and improvement of our AI algorithm have been ongoing processes. By embracing an agile approach, we have been able to incorporate new ideas and techniques into the algorithm quickly. Continuous experimentation and testing have allowed us to explore alternative approaches, such as analyzing the number of bright voxels, and assess their impact on LVO detection. The ability to modify and fine-tune the algorithm has been essential in maintaining its performance, adapting to different hospital settings, and effectively addressing emerging challenges in stroke care.

💰 Planning for Post-FDA Clearance Development

Post-FDA clearance development is a critical phase in the evolution of any medical device or system. We learned early on that the majority of the development work happens after obtaining clearance. Therefore, it is crucial to plan for post-clearance development, both from an R&D and regulatory perspective. Ensuring scalability, flexibility, and easy modification of the algorithm is essential to accommodate future improvements and comply with regulatory requirements. By planning ahead, we have been able to continuously enhance our AI-powered stroke care system and adapt it to the evolving needs of the healthcare industry.

📊 Performance Evaluation in the Real World

To gain a comprehensive understanding of our AI system's performance, we conducted a real-world study that involved a wide range of hospitals, scanners, and technicians. This study allowed us to evaluate the performance of our algorithm in a diverse and challenging environment. The results were promising, with a sensitivity and specificity of around 94-96%. This real-world data also enabled us to identify hospitals or scanner models with lower performance and take proactive measures to improve their outcomes. The insights gained from this study have contributed to the continuous refinement of our AI algorithm and the delivery of high-quality stroke care.

📈 Big Data Investigation in Stroke Care

The availability of a large dataset from various hospitals facilitated in-depth investigations into stroke care practices. We analyzed the data to identify hospitals or cities where the performance of our system was suboptimal. By reaching out to these hospitals and addressing factors like scan quality and protocol discrepancies, we could improve the AI system's performance in those specific locations. The wealth of data also allowed us to observe trends, Patterns, and variations in stroke care practices, leading to valuable insights that further enhance the accuracy and effectiveness of our AI algorithm.

💪 Conclusion

The introduction of AI in stroke care has revolutionized the diagnosis and treatment of stroke patients. Through continuous research, development, and clinical validation, our AI-powered system has demonstrated its effectiveness in reducing the time to treatment, improving patient outcomes, and ultimately saving lives. Challenges in healthcare marketing and generating clinical evidence have been overcome by conducting pre-post comparison studies, exploring randomized controlled trials and stepped wedge designs, and continuously refining the AI algorithm. The scalability, flexibility, and performance of our system make it an indispensable tool in the fight against stroke.
