What this trial studies

This project aims to broaden access to data from patients who participated in the Salford Lung Study, focusing on asthma and chronic obstructive pulmonary disease (COPD). By collecting additional subject-level data through electronic medical records and a patient questionnaire, researchers hope to gain insights into the entire disease journey of these patients over a period of up to 10 years. This observational study will enhance the understanding of disease risk, treatment, and progression in asthma and COPD patients.

Who should consider this trial

Good fit: Ideal candidates are individuals who participated in the original Salford Lung Study and can provide consent for additional data collection.

Not a fit: Patients who were lost to follow-up, withdrew consent, or are too ill to participate may not benefit from this study.

Why it matters

Potential benefit: If successful, this project could lead to improved treatment strategies and better management of asthma and COPD.

How similar studies have performed: Other studies have successfully utilized extensive patient data to improve understanding of chronic diseases, making this approach promising.
