Background: Asthma is a disease that can be fully controlled and treated, and the most important components of treatment are patient? health education.

Aims: To investigate how the level of knowledge of asthmatics patients affects asthma control and the patient's quality of life

Methods: The study was done by a hospital-based experimental research. Asthma knowledge questionnaires (AKQ) from the University of Newcastle, and asthma quality of life (AQoL) was assessed using the ?Sydney Asthma Quality of Life Questionnaire?, asthma control was assessed using the ?Asthma Control Test? before the health education training, 3 and 6 months after the training.

Results: A total of 50 people. The score of the AKQ was 35.2±6.8 before training, 47.5±5.9 was after 3 months (post-test I) and 51.9±2.9 after 6 months (post-test II) has increased (F(2:90)=153.8, p<0.001). 30.0% before training of the patients surveyed had ?adequate knowledge?, while adequate knowledge had 88.0% in post-test I and 100% had in post-test II. The assessed the level of asthma control before training 10.0% were ?well controlled?, 8.0% were ?partly controlled? and 82.0% were ?uncontrolled. Although there was a significant improvement in the level of control after the health education training (F (2:90)=26.3; p<0.001), no difference was observed between post-tests I and II (p=0.626). The overall asthma quality of life score was 3.3±1.2 before training, after training was 2.1±1.1 and 1.8±1.0, it was improved (F(2:90)=39.7, p<0.001). However, there was no significant difference was observed between post-tests I and II.

Conclusions: After training, there was a significant improvement in the asthma knowledge, AQoL and asthma control.
