Respiratory medicine physicians prescribe many different kinds of medications depending on patient's condition. To examine an outside pharmacy's ability to meet the demand of our respiratory prescription services, we developed a questionnaire for all the patients who came to our outpatient department from November 1, 2015 to January 31, 2016. A total of 298 of 330 patients answered the questionnaire. Overall, 169 patients mainly went to the pharmacy near our hospital, whereas 64 patients mainly went to another pharmacy. Specifically, 23 of 219 patients who answered the question “When you went to the pharmacy with prescription, have you ever been not immediately given medication?”, were not immediately given medication by the pharmacy. The results show that the other pharmacy significantly delayed medication compared with the one near our hospital. Interestingly, there were many types of inhaler cases that were out of stock in both pharmacies. Also, we found that 9 of 11 patients who were not provided medication on the spot acquired the medication within 1 or 2 d. Further, 10 of 20 patients who were not provided medication on the spot were only able to obtain the medication once. We did not observe any changes in patients' physical condition due to the delay in medication.
