About

The aim of the present study is to explore if the "Health Lung" application of smart phone and portable spirometry "ezOxygen" can further improve asthma control for chronic asthma adult patients with well asthma control (ACT 20~24, but not 25), compared to hospital-based usual care in a medical center.

Full description

Asthma is a chronic inflammatory disease. Despite we have academic treatment guidelines, and the asthma treatment develops persistently, many asthma patients do not have well control.

Asthma Control Test (ACT) is a patient self-administered tool for identifying those with poorly controlled asthma. ACT includes 5 items on 5-point scale, with 4-week recall on symptoms and daily functioning. The scores range from 5 (poor control of asthma) to 25 (complete control of asthma), with higher scores reflecting greater asthma control. An ACT score >19 indicates well-controlled asthma.

In addition to correct diagnosis and prescription by physicians, achieving asthma well control depend on the patient's ability of self- management.

The self-management of asthma patients includes monitor of symptoms, monitor of peak expiratory flow, compliance of inhaler and avoiding the asthma triggers.

Portable digital tools may be the possible solution for home monitor of asthma patients. Through the application of mobile phone and hand-held mobile spirometry, asthma patients can monitor their symptoms and lung function at home outside of hospital.(5-7)。

"Health Lung" (AstraZeneca Pharmaceuticals LP) is the application for mobile phone to help asthma care and is available freely in Google Play. Health Lung can be connected to the mobile spirometry, "ezOxygen" (Genius Holding Co.,Ltd Taiwan Branch).

Therefore, the functions of this App. include asthma control monitor, lung function monitor, controller and reliver inhaler reminder and recording, asthma educational topics in brief and information of air quality. The physicians can get the information about control status, lung function, adherence of controller and usage of reliver of patients between each clinical visit, if patients following the instruction of "Health Lung".

However, how the patients are willing to use digital tools at home and what is the real impact on the current hospital-based asthma care need to be validated.

Health Lung can be connected to the mobile spirometry, "ezOxygen" (Genius Holding Co.,Ltd Taiwan Branch). The functions of Health Lung App. include asthma control monitor, lung function monitor, controller and reliver inhaler reminder and recording, asthma educational topics in brief and information of air quality Subjects can get reminder to use inhaler on schedule, input ACT score to evaluate the asthma control, get education materials about asthma and operate spirometer to access lung function outside of hospital. he physicians in charge will get the information about control status score by ACT, adherence of controller and usage of reliver of patients between each clinical visit, if patients following the instruction of "Health Lung".
