Validation and Clinical Utility of the Lung Sliding Index (LSI) for Differentiating Pulmonary Diseases

Recruiting now

Conditions studied: COPD, ILD, Bronchiectasis, Pneumothorax, Pneumonia, Pleural Effusion Disorder, Pulmonary Oedema

In brief

This upcoming case-control study aims to confirm the Lung Sliding Index (LSI), a new ultrasound score that measures how well the pleura moves, in various lung diseases. The study will check how well the LSI can tell apart different lung diseases (like pneumothorax, interstitial lung disease, COPD, pneumonia, and pulmonary edema), how it relates to signs of disease severity, and how consistent the results are between different operators who have received the same training. Secondary objectives include assessing patient and operator satisfaction and feasibility using validated Likert scales.
