Dear Editor
The COVID-19 pandemic has posed unprecedented challenges to global healthcare systems, especially in the timely assessment of disease severity and resource allocation [1]. Traditional clinical and imaging markers, although useful, often lack the sensitivity and speed necessary for early and accurate patient classification. In this context, artificial intelligence (AI) has emerged as a transformative tool in assessing COVID-19 severity, aiding diagnosis, prognosis, and clinical decision-making [2].
AI, particularly through machine learning (ML) and deep learning (DL) algorithms, can process extensive volumes of clinical, imaging, and laboratory data with remarkable speed and accuracy [3]. For instance, convolutional neural networks (CNNs) have shown high accuracy in detecting COVID-19-related abnormalities in chest CT and X-ray images, often outperforming conventional radiological assessments in identifying ground-glass opacities and fixation patterns [4]. CNNs with three layers use medical datasets to recognizing images for good identification, and python language for training the proposed deep transfer learning models [5]. We should be mentioned CheXNet, the largest publicly available chest X-ray dataset that can detect 14 diseases hinging on X-ray images [6]. So this ML based models can compete with radiologists in analyzing radiology images by extra tools, for example using natural language processing (NLP) for high level transforming like IBM Watson Health [7].
Additionally, AI models that integrate vital signs, oxygen saturation, comorbidities, and biomarkers such as D-dimer and C-reactive protein have shown promise in predicting disease progression and risk of ICU admission [8]. SOFA (sequential organ failure assessment) is a clinical scoring system used to evaluate the function of vital organs in critically ill patients in the ICU. It measures the severity of organ failure based on the respiratory, cardiovascular, hepatic, renal, hematologic, neurologic. Each organ is scored from 0 to 4 (normal to most severe dysfunction), and the total score 0 to 24 that shown the degree of multi-organ failure. DEEP SOFA is a cutting-edge deep learning-based model that help more accurate organ failure prediction, improved ICU management, integration of multi-source data, personalized treatment and can be used by trained nurses and doctors [9].
One notable application is the development of AI-based triage tools in emergency department, that can quickly identify high-risk patients and prioritize care, particularly when healthcare resources are limited [10]. To illustrate this, knowledge-augmented temporal model for emergency care (KATE) is an advanced ML model for prediction and making better decisions than humans. KATE with some steps such as multimodal data integration, feature extraction, hybrid neural network, outcome prediction and explainable AI with some better primary result use in sophisticated but small hospitals [11]. In addition, AI-based predictive models are used to predict the need for ventilatory support and the likelihood of recovery or mortality, improving individualized patient management [12].
Despite these advances, challenges remain. Algorithm transparency, data privacy, and the need for external validation across diverse populations are important concerns [13]. Most AI models are developed using retrospective datasets, often with regional biases, which limits their generalizability [14]. Furthermore, integrating AI into routine clinical workflows needs interdisciplinary collaboration and strong regulatory frameworks [15].
However, the pandemic has catalyzed the acceptance and adoption of AI in clinical medicine. Future strategies should concentrate on creating ethically sound, clinically validated, and interpretable AI systems tailored for pandemic response [16]. Integrating real-time data from wearable devices, electronic health records, and cloud-based platforms can increase the capacity of AI to provide timely and accurate assessments of COVID-19 severity [17].
In conclusion, AI shows a powerful complement to the fight against COVID-19, providing tools to accurately evaluate severity and optimize resources. Continued investment in AI research and its responsible implementation critical to strengthening global preparedness for current and future pandemics.
