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.
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.
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.
使用便携式设备进行家庭肺功能测定可为哮喘管理提供一种潜在的替代方法，可减少对医院的依赖并提高可及性。本研究旨在评估在无直接医疗监督的情况下进行支气管扩张剂反应（BDR）测试的家庭肺功能测定计划的可行性。方法：对一家三级医院的47名哮喘患者进行了一项前瞻性观察性研究。参与者收到了明确的指导，并在家中使用便携式设备进行了带有BDR测试的用力肺活量测定。主要结果包括肺功能测定质量、与医院测试相比的变异性以及患者满意度。
尽管与医院测试相比，用力肺活量（FVC）和一秒用力呼气量（FEV1）的变异性更大，但共有78%的参与者获得了高质量的肺功能测定结果（根据ATS/ERS标准为A或B）。然而，结果在临床上仍然可以接受。患者对该设备的满意度很高，强调了其易用性和便利性。
带有BDR测试的家庭肺功能测定是哮喘随访的一种可行工具，在减少基于医院的测试的同时保持了可接受的质量。尽管需要改进以尽量减少变异性并提高一致性，但该计划有可能优化哮喘管理、增加可及性并减轻医疗机构的负担。
