 Adherence Starts with Knowledge-20 (ASK-20) is a questionnaire to investigate the cause decreasing medication adherence.


 In this study, we investigated inhaled drug adherence status of asthma patients by ASK-20.


 Seventy-four patients with bronchial asthma whose symptoms are relatively stable (mean age 48 year-old, 36 males, 38 females) used inhaled drug.


 We analyzed and evaluated for each items from 5 points to 1 point in the order of the heavy degree among five choice answers in based on describe about inhaled drug of the ASK-20 by subjects.


 Lifestyle: Ratio of over 4 points was 48.6% in Q1 and 12.2 %, 2.7%, 10.8%, 9.5%, 18.9% in Q2, Q3, Q4, Q5 and Q6.

 Attitudes and Beliefs: Ratio of below 2 points was 83.8% in Q7 and 63.5% in Q8.

 Help from Others: Ratio of below 2 points was 55.4% in Q9. 

 Talking with Healthcare Team: Ratio of below 2 points was 87.8%, 89.2%, 87.8% in Q10, Q11 and Q12.  

 Talking Medicines: Ratio of over 4 points in Q13, Q14 and Q15 was each 36.5%, 21.6% and 5.4%.

 Have You…: Ratio of over 4 points in Q16, Q17, Q18, Q19 and Q20 was each 31.1%, 5.4%, 4.1%, 1.4% and 27.5%.

 In results of Q1 and Q2, patients who sometimes forget medicine were about half ratio, but about 90% of patients had been consulted before drugs are eliminated.

 Noteworthy, 36.5% of patients didn’t like inhaling more than twice a day in results of Q13 and Q14.
 And about 30% of patients was in the wrong number and amount of taking medicine by result of Q16.
 Or about 20% of patients did not have the medicine to the specified time in result of Q20.     

It is considered that their adherence increases if we could switch to inhaled drug for once a day because approximately 40% patients have thought troublesome about twice inhalation a day.
