Subject who are agree to enrol in the study will be randomized into intervention and control group. Subjects in intervention group will be undergone one session of an AEP, however there are no intervention for control group but continue routinely follow up in Respiratory Clinic. To obtain the study result descriptive and inferential statistical analysis will be performed. To analyse the statistical significant of the change in patients' health outcome the pre and post of AEP independent t-test or chi-square test will be used.The expected finding of this study is to determine the effectiveness of AEP result in of patients' knowledge regarding asthma disease, medication adherence and inhaler technique, pre and post of AEP.
