Introduction

In this article, we will explore the revolutionary Clarity AI, an AI-Based algorithm designed to empower clinicians at the bedside. We will discuss how Clarity AI works, its key features, and the findings of a validation study. Additionally, we will examine the workflow in hospitals using Clarity AI and the benefits it offers in terms of efficient and accurate diagnosis and treatment decisions.

Understanding Clarity AI

Clarity AI is an AI-based algorithm developed to analyze EEG data and detect seizures in patients. It is designed to provide clinicians with valuable insights into the presence and burden of seizures, aiding in treatment decision-making processes. By utilizing advanced machine learning techniques, Clarity AI recognizes specific features associated with seizures and generates output in the form of seizure burden percentage.

How Clarity AI Works

3.1. EEG Analysis

Clarity AI operates by analyzing the last 5 minutes of EEG data. This data is segmented into 10-Second intervals, allowing for a detailed examination of the signal. By focusing on these shorter intervals, Clarity AI ensures high precision in detecting seizure activity.

3.2. Recognition of Seizure Features

The algorithm has been trained to identify at least 52 different features of the EEG signal that indicate the presence of seizures. These features include various Patterns and abnormalities that are associated with seizure activity. Clarity AI leverages the knowledge gained from its training to accurately identify and interpret these features.

3.3. Determining Seizure Burden

Using the recognized features, Clarity AI determines whether each 10-second segment of the EEG data contains seizure activity. These outputs, indicating seizure or no seizure, are then averaged over a 5-minute window to calculate the seizure burden percentage. This percentage represents the proportion of segments containing seizure activity during the given time frame.

Validation Study Findings

In a comprehensive validation study, Clarity AI's performance was evaluated and compared to human interpretations of EEG data. Multiple EEG experts analyzed 353 EEGs and provided their assessments, which served as the ground truth for the study. The results were then compared to the outputs generated by Clarity AI.

4.1. Comparison of Human and Clarity AI Performance

The validation study revealed that Clarity AI achieved a sensitivity of 100% in detecting status epilepticus, meaning it successfully identified all cases of this severe seizure Type. Moreover, the algorithm accurately identified a significant proportion of EEGs with diffuse or benign abnormalities, providing valuable insights into patients' conditions.

4.2. Sensitivity for Detecting Status Epilepticus

Using a threshold of 90% or higher, Clarity AI demonstrated a sensitivity of 100% in detecting status epilepticus. Although this high sensitivity may result in some over-calls, the majority of these cases were highly epileptiform patterns, which could benefit from anti-seizure medications.

4.3. Importance of AI Triage

Clarity AI's ability to triage EEG cases into highly abnormal findings and non-urgent ones allows for more efficient resource allocation. Cases with a seizure burden of less than 10% can be handled by non-status epilepticus readers, reducing the need for immediate expert intervention. This triaging process prevents over-aggressive treatment in cases where it is not necessary.

Workflow in Hospitals

In hospitals where Clarity AI is implemented, it is crucial to understand its role as an additional clinical data point. The algorithm should be viewed as a tool that aids clinicians in decision-making rather than a standalone diagnostic tool.

5.1. Additional Clinical Data Point

Clinicians should consider the AI-generated outputs from Clarity AI alongside clinical suspicion when determining the appropriate treatment path. The accumulated clinical data and the information provided by Clarity AI play complementary roles in reaching an accurate diagnosis.

5.2. Treatment Decision Making with Clarity AI

Using Clarity AI, treatment decisions can be fine-tuned based on the seizure burden percentage. If the clinical suspicion is high and Clarity AI indicates a seizure burden of over 90%, immediate treatment should be pursued, and an urgent EEG expert Read should be requested. Conversely, if the AI Suggests a seizure burden of less than 10% or zero percent, the likelihood of prolonged seizures is highly unlikely, allowing for a more conservative treatment approach.

Benefits of Using Clarity AI in Hospitals

Implementing Clarity AI in hospitals yields numerous benefits that enhance the diagnostic and treatment processes for patients with seizure activity.

6.1. Shortening Time to Treatment for Non-Convulsive Status Epilepticus

By incorporating Clarity AI into the workflow, hospitals can significantly reduce the time it takes to initiate treatment for non-convulsive status epilepticus cases. The algorithm's accuracy in detecting these critical seizures ensures prompt intervention, leading to improved patient outcomes.

6.2. Eliminating Over-Aggressive Treatment

The utilization of Clarity AI helps prevent cases of unnecessary over-aggressive treatment, such as intubation, paralysis, and ICU admissions. By accurately assessing the seizure burden percentage, clinicians can make informed decisions, sparing patients from unnecessary procedures and reducing healthcare costs.

Conclusion

Clarity AI is a groundbreaking AI-based algorithm that empowers clinicians at the bedside by providing valuable insights into seizure activity. Its exceptional performance in detecting seizures, triaging cases, and optimizing treatment decisions makes it an invaluable tool in the field of epilepsy management. By incorporating Clarity AI into hospital workflows, healthcare professionals can enhance patient care, reduce unnecessary interventions, and improve overall outcomes.
