AI-Powered Causal Discovery Explores Vasospasm in ICU Patients
Researchers at Universiteit Gent are utilizing Artificial Intelligence (AI) to investigate the causes of vasospasm in Intensive Care Unit (ICICU) patients following a brain hemorrhage. This condition, where blood vessels in the brain suddenly narrow, can lead to oxygen deprivation, brain damage, or death. Despite being known for decades, the exact mechanisms behind vasospasm remain poorly understood. The study employs AI to analyze vast amounts of patient data, including the large public dataset MIMIC-IV, which contains medical records from thousands of ICU patients. A key challenge identified was the difficulty in accurately identifying vasospasm cases from structured patient data, as official diagnoses were often missing, while mentions were more frequent in doctors' and radiologists' reports. To address this, a system was developed that combines structured data with text from medical records, using a language model similar to ChatGPT to process hundreds of discharge letters and radiological reports.
