The current practice of monitoring is to follow-up the patient during monthly control visits. However, it might be insufficient for effective detection of the exacerbations, especially at the first periods after LTx. In this pilot study, we evaluated the feasibility of home monitoring of the patients using a portable spirometer.Methods: The patients after LTx from Silesian Centre for Heart Diseases (Zabrze, Poland) were equipped with the portable spirometer (AioCare, HealthUp) on discharge from hospital. They were asked to perform daily spirometry tests (after online training) and track the respiratory symptoms in a mobile app. The number of tests, adherence and detected exacerbation were evaluated.Results: 11 patients (6 females; 44.8±12.3 y.o.) were recruited between December 2021 – May 2022; the range of the time period of monitoring was between 25-160 days (mean: 79±49 days). Total number of spirometry tests was 960 (87±53 per patient; mean adherence level: 84±19%); 65.2% of them met all ATS/ERS correctness criteria (mean: 59.7±34.6% per patient); at least one correct maneuver was performed in 93% of tests. 3 patients, due to decreasing spirometry parameters, were called to the clinic and early stages of the inflammation process were observed.Conclusions: The results showed that the patients after lung transplantation are able to self-monitor using portable spirometers with a large level of adherence. Introducing this method into the clinical practice may detect the early signs of transplant rejection which cannot be caught during control visits in a clinic.FootnotesCite this article as Eur Respir J 2022; 60: Suppl. 66, 4629.This article was presented at the 2022 ERS International Congress, in session “-”.This is an ERS International Congress abstract.
