Brief summary
Aim: To investigate the potential for N-Tidal to improve COPD diagnosis and enable detection of pre-COPD\*. Objectives: 1. To assess the performance of TidalSense COPD Diagnostic Algorithms for COPD diagnosis in a real-world, head-to-head comparison with post-bronchodilator spirometry among FRONTIER programme participants. 2. To assess the performance of TidalSense COPD Diagnostic Algorithms for identification of pre-COPD. 3. Evaluate TidalSense COPD Diagnostic Algorithms ability to identify those at risk of developing COPD within 1-year. Aim: Explore the blood biomarker profile among FRONTIER Programme participants to explore a potential role in early COPD identification. Objectives: 1. Investigate the blood biomarker profile (obtained from the Hull Lung Health Study data) of people with i) confirmed COPD, ii) pre-COPD, and iii) no evidence of COPD. 2. Explore a potential role for blood biomarkers in COPD diagnostics. * Pre-COPD is defined, as per the GOLD Report 2023, as individuals who have respiratory symptoms and/or other detectable structural and/or functional abnormalities in the absence of airflow obstruction on forced spirometry. For the purpose of this study, respiratory symptoms will be classified as a CAT score \> 10 during FRONTIER clinic attendance and presence of emphysema on low-dose CT considered evidence of structural lung abnormalities

Primary
| Measure | Time frame | Description |
|---|---|---|
| To assess the performance of TidalSense COPD Diagnostic Algorithms for COPD diagnosis in a real-world, head-to-head comparison with post-bronchodilator spirometry among FRONTIER programme (NHS Lung Health Check) participants. | 1 year | We will investigate the performance of TidalSense COPD Diagnostic Algorithms (including the sensitivity, specificity, positive predictive value and negative predictive value of TidalSense 'likely' or 'highly likely' outputs) for COPD diagnosis in a real-world, head-to-head comparison with post-bronchodilator spirometry among NHS Lung Health Check participants. It is anticipated that \ 900 patients will participate in the programme. |
| To assess the performance of TidalSense COPD Diagnostic Algorithms for identification of pre-COPD. | 1 year | We will investigate the sensitivity, specificity, positive predictive value and negative predictive value of TidalSense 'likely' or 'highly likely' outputs for identifying those that go onto receive a diagnosis of COPD within 1-year of initial review (Pre COPD). |
| Evaluate TidalSense COPD Diagnostic Algorithms ability to identify those at risk of developing COPD within 1-year | 1 year | We will investigate the sensitivity, specificity, positive predictive value and negative predictive value of TidalSense 'likely' or 'highly likely' outputs for identifying those at risk of developing COPD within 1-year |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Explore a potential role for blood biomarkers in COPD diagnostics including investigating the blood biomarker profile (obtained from the Hull Lung Health Study data) of people with i) confirmed COPD, ii) pre-COPD, and iii) no evidence of COPD | 1 year | blood biomarker profiles (eosinophils, nTProBNP, fibrinogen, CRP, and IL-6) will be reported descriptively for those with confirmed COPD, pre-COPD and no COPD. Initial univariable pre-screening will inform variable inclusion in a multivariable logistic regression model to explore factors associated with COPD and pre-COPD diagnosis. Identified associated factors will be considered for inclusion in Tidalsense's diagnostic algorithms and the impact on performance investigated. |
