The primary goal of the Care for Asthma via Mobile Phone (CAMP) service is to provide an effective method by which Taiwan's asthma patients can easily monitor their asthma symptoms using a common mobile phone. With the CAMP service, the patient uses his own cellular phone to submit his daily peak expiratory flow rate (PEFR) and answer a simple questionnaire regarding to daily activities. The CAMP service participant then receives an asthma symptom assessment and care suggestion message immediately after imputing his information. This assessment, which is in accordance with the World Health Organization's (WHO) Global Initiative for Asthma (GINA) standard, includes weather conditions that might adversely affect the asthma patient (e.g. temperature, pollen count, etc.). This information is, in turn, used to advise the asthma patient how to avoid a severe asthmatic attack.
