Insights into Digital MedicRehApp Maintenance Model for Pulmonary Telerehabilitation: Observational Study.

Maintenance strategies after center-based pulmonary rehabilitation (CBPR) are currently needed. This study aimed to evaluate the feasibility and effect on the quality of life of a home-based pulmonary rehabilitation (HBPR) program delivered by a digital app. As secondary objectives, the patients' adherence, symptoms, effort tolerance changes, and safety were evaluated. This was a single-arm prospective observational monocentric study on 30 patients referred for chronic respiratory diseases. The prescription and evaluations of the HBPR programs performed at the pulmonary facility and delivery of structured exercise and counselling by the digital health tool were achieved under the supervision of a respiratory therapist. Digital capabilities included aerobic, strength, and respiratory exercises, which were monitored with a fitness tracker. The engagement rate of the HBPR after the CBPR was 1:10. The EuroQoL VAS score increased from 66.2 ± 16.28 to 75.60 ± 16.07 (
