NIH-funded research R21 grant

Using machine learning to predict disease progression and survival in patients with severe limb ischemia.

Official title: Machine learning-based staging system to predict chronic limb-threatening ischemia disease progression and survival: A secondary analysis of the BEST-CLI trial data

Funded at Univ of North Carolina Chapel Hill · NIH-11001221 · Data updated 2026-11-12

This study is working on a smart system that helps doctors understand how serious chronic limb-threatening ischemia (CLTI) is for patients and how it changes over time, so they can give the best treatment possible and improve health outcomes.

Who could benefit from this research

Could help

Ideal candidates for this research are adults diagnosed with chronic limb-threatening ischemia who are undergoing treatment for this condition.

Less likely to help

Patients who do not have chronic limb-threatening ischemia or those who are not receiving treatment for this condition may not benefit from this research.

What this research studies

This research aims to develop a machine learning-based system to assess the severity and progression of chronic limb-threatening ischemia (CLTI) in patients. By analyzing data from the BEST-CLI trial, the study will create a comprehensive staging system that evaluates individual disease burden and mortality risk at diagnosis and throughout treatment. This approach seeks to improve patient outcomes by tailoring treatment strategies based on predicted disease progression and survival rates. Patients will be monitored for their response to various interventions, including surgical and medical therapies.

Why it matters

Potential benefit: If successful, this research could lead to more personalized treatment plans that significantly improve survival rates and quality of life for patients with CLTI.

How similar studies have gone: Previous studies have shown promise in using machine learning for predicting outcomes in various medical conditions, suggesting potential success for this novel approach in CLTI.
