Self-monitoring of Spirometry & Symptoms Via patientMpower App in Idiopathic Pulmonary Fibrosis

Single-arm, open-label observational study in idiopathic pulmonary fibrosis (IPF) patients receiving usual care at an interstitial lung disease specialist center. The objectives are \[1\] to characterise the longitudinal trends of patient-measured Forced Vital Capacity (FVC) and impact of IPF on daily life Patient Reported Outcome Measures (PROM) in a cohort of patients with IPF \[2\] to determine the correlation (if any) between patient-measured FVC and PROMs with clinic-observed measurements and \[3\] to assess if longitudinal trends in patient-measured FVC are predictive of clinical health outcomes in IPF. An additional purpose is to assess the acceptability and utility of the patientMpower app in helping IPF patients and their healthcare professional caregivers manage their condition. Patients will record FVC, symptoms (e.g. dyspnea) and activity (step count) daily and PROM once a week on the patientMpower app. The planned observation period is sixteen weeks. No additional clinic visits are required (versus usual care). In-clinic assessments of lung function, dyspnea and PROM will be done at baseline and study end. Patients and healthcare professionals will provide their opinion on utility and acceptability of patientMpower app at study end.
