Long Term Follow up of the LTOG Cohort

This project will involve both retrospective and prospective data collection from participants enrolled in the LTOG cohort studies. We will perform long-term Chronic Lung Allograft Dysfunction (CLAD) phenotyping of lung transplant recipients who participated in the LTOG cohort studies utilizing data collected for routine clinical visits. Surviving lung transplant recipients who participated in the LTOG cohort studies will be recruited to enroll in the longitudinal portion of the project. The longitudinal component will include follow-up data collection at 6 month intervals while alive until study termination, study withdrawal, or no longer being seen for follow-up at the participating center. Follow-up data collection will include clinical data collected by study coordinators by reviewing medical records, functional assessment through administration of the Short Physical Performance Battery (SPPB), blood collection and surveys. Data from this project will be linked to data and samples collected during the LTOG cohort or ancillary studies.
