Abstract
It is important that physicians control asthma symptoms based on daily conditions of patients. The Childhood Asthma Control Test (C-ACT) has recently been developed, and its Japanese version has already been available. We compared C-ACT score with the patient's symptoms score converted from the patient's daily reports. The frequency of PEF reduction and that of rescue use of inhaled beta 2 agonists were also compared with C-ACT, for the evaluation of its effectiveness. C-ACT scores has close correlations with symptoms based on patient's daily reports and the need of rescue use of inhaled beta 2 agonists, but not with the frequency of reduced PEF. The Childhood Asthma Control Test of Japanese version is in general effective in clinical settings, but physicians should understand that it did not reflect respiratory functions.
