Abstract

BACKGROUND
Asthma patients may experience acute episodic exacerbation. The guidelines recommend that written action plan should be given to asthma patients. However, no one can predict when and where acute exacerbation will happen. As people carry smart phone almost anytime and anywhere, smartphone application could be a useful tool in asthma care. We evaluated the feasibility of the ubiquitous healthcare system of asthma care using a smartphone application (snuCare) based on the self-management guideline or action plan.
METHODS
Forty-four patients including fragile asthmatics were enrolled from Seoul National University Bundang Hospital between December 2011 and February 2012. They were randomly assigned into application user (n = 22) or application nonuser group (n = 22). We evaluated user-satisfaction, and clinical parameters such as asthma control, Quality of Life Questionnaire for Adult Korean Asthmatics, and the adherence of patients.
RESULTS
The characteristics were similar at baseline between the 2 groups except those who treated with short-term systemic steroid or increased dose of systemic steroid during previous 8 weeks (user vs. nonuser: 31.8% vs. 4.5%, p = 0.020). Total of 2,226 signals was generated during 8 weeks including 5 risky states. After eight weeks, the users answered that it was very easy to use the application, which was shown in highest scores in terms of satisfaction (mean ± standard deviation, 4.3 ± 0.56). Seventy-three percent of patients answered that the application was very useful for asthma care. User group showed improved the adherence scores (p = 0.017). One patient in application user group could avoid Emergency Department visit owing to the application while a patient in nonuser group visited Emergency Department.
CONCLUSION
The ubiquitous healthcare system using a smartphone application (snuCare) based on the self-management guideline or action plan could be helpful in the monitoring and the management of asthma.
