Conclusion
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.
Consideration
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.
