๐ Background
Angioedema (AE) is characterized by transient, localized swelling, but its underlying causes can vary widely. This variability complicates diagnosis and treatment, making it essential to identify specific AE types accurately. Traditional diagnostic methods often fall short, highlighting the need for innovative approaches such as machine learning to enhance diagnostic accuracy and patient outcomes.
๐๏ธ Study
The study aimed to develop a robust machine learning model to classify different types of angioedema. Researchers conducted a comprehensive literature search to identify clinical characteristics of AE, collaborated with 12 European AE centers to formulate relevant questions, and ultimately tested and optimized a random forest model using data from 342 patients diagnosed with one of six AE types.
๐ Results
The optimized random forest model demonstrated impressive performance, achieving a true positive rate of 94% for hereditary AE due to C1 inhibitor deficiency. Overall, the model reached a percentage accuracy of 89.2% and a Kappa value of 81.8%, indicating a high level of agreement with expert diagnoses across all six AE types.
๐ Impact and Implications
The findings from this study could revolutionize the way angioedema is diagnosed. By leveraging machine learning algorithms, healthcare professionals can potentially achieve more accurate and timely diagnoses, leading to improved patient management and treatment outcomes. This innovative approach may pave the way for broader applications of AI in various medical fields, enhancing diagnostic precision and patient care.
๐ฎ Conclusion
This study highlights the transformative potential of machine learning in the classification of angioedema types. With a high accuracy rate and strong agreement with expert diagnoses, the random forest model represents a significant step forward in AE diagnosis. Continued research and development in this area could lead to even more sophisticated diagnostic tools, ultimately benefiting patients and healthcare providers alike.

Classification of angioedema types using decision tree modeling.
Abstract
INTRODUCTION: All angioedema (AE) presents with transient, localized swelling; however, the underlying causes, prognosis, and treatments vary significantly. Consequently, identifying a specific AE type is challenging.
METHODS: We aimed to apply a machine learning (ML) model to improve AE diagnosis. Random forest (RF) ML was used to create a prediction model for diagnosing correct AE types. Development comprised a literature search to establish AE’s clinical characteristics, developing and translating questions in collaboration with 12 European AE centers, and selecting, testing, validating and optimizing the established ML model. Analysis included 342 specialist-diagnosed patients with one of six AE types.
RESULTS: The final optimized RF model correctly identified AE types with true positive rates of up to 94% in hereditary AE due to C1 inhibitor deficiency (C1INH), with a Percentage Accuracy of 89ยท2% and a Kappa value of 81ยท8% across the six AE types, with a high agreement with the diagnoses made by experts.
DISCUSSION: This is the first ever reported ML algorithm designed to pre-assess to aid AE diagnosis.
