%X Introduction: This manuscript analyzes the exacerbations recorded by the Prevexairapplication through the daily analysis of symptoms in high-risk patients with COPDand explores its usefulness in assessing clinical stability with respect to that reported invisits.Patients and Methods: This study is a multi-centre cohort of COPD patients with theexacerbator phenotype who were monitored over 6 months. The Prevexair application wasinstalled on the patients’ smartphones. Patients used the app to record symptom changes, useof medication and use of healthcare resources. It is not established a recommended actionplan when worsening of symptoms. At their clinical visit during the follow-up period,patients were asked about exacerbations suffered during these 6 months of monitoring.The investigators who conducted the visit were blinded about the Prevexair app records.Results: The patients experienced a total of 185 exacerbations according to daily records inthe app whereas only 64 exacerbations were recalled during medical visits. Perceptionbecame more accurate for severe exacerbations (kappa 0.6577), although we found no factorsthat predicted poor recall. The proportion of 72.5% patients were classified as unstable if theexacerbations captured by Prevexair were used to define stability, versus 47.8% if theexacerbations recall in visit was used. Two-thirds of the exacerbations recorded in thePrevexair application were not reported to doctors during their clinical visits. Almost halfwere treated with oral corticosteroids and/or antibiotics and more than one-quarter of theexacerbations treated did not seek medical attention.Conclusion: The findings of this cohort study confirm that patients do not always rememberthe exacerbations suffered during their medical visit. The prevexair application is useful inmonitoring COPD patients at high risk, in order to a better assessment of exacerbations ofCOPD during medical visits. Further research must be carried out to evaluate this strategy inclinical practice.Keywords: chronic obstructive pulmonary disease, telemonitoring, mobile health,exacerbations, clinical prediction, management, electronic patient record
