Viability of a new home program of forced spirometry with bronchodilator response measurement in the assessment of patients with asthma

# metadata.dc.description.abstract[].value
Background: Home spirometry using portable devices offers a potential alternative for asthma management by reducing hospital dependence and improving accessibility. This study aimed to assess the feasibility of a home spirometry program with bronchodilator response (BDR) testing performed without direct medical supervision. Methods: A prospective observational study was conducted with 47 asthma patients from a tertiary hospital. Participants received clear instructions and performed forced spirometry with BDR testing at home using a portable device. The primary outcomes included spirometry quality, variability compared to hospital tests, and patient satisfaction. Results: A total of 78% of participants achieved high-quality spirometry (A or B, according to ATS/ERS -criteria), despite greater variability in forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) compared to hospital tests. However, the results remained clinically acceptable. Patients reported high satisfaction with the device, highlighting its ease of use and convenience. Conclusions: Home spirometry with BDR testing is a feasible tool for asthma follow-up, maintaining acceptable quality while reducing hospital-based testing. Although improvements are needed to minimize variability and enhance consistency, this program has the potential to optimize asthma management, increase accessibility, and reduce the burden on healthcare facilities.
