Challenges in Instructing Adult Asthma Patients in the Use of Inhalers / 薬剤疫学

ABSTRACT

<B>Objective</B> The objective of this study was to clarify issues in providing more effective guidance in the drug treatment, especially the usage instructions of inhaled steroids, of adult bronchial asthma patients by verifying which points of explanation are especially important in controlling attacks, and whether or not issues exist stemming from a evaluation gap between patients and pharmacists regarding the degree of explanation and understanding on the usage instructions of inhaled steroids.<br><B>Method</B> Our survey targeted pharmacists working at community pharmacies in eight different areas of Japan, along with adult bronchial asthma patients using these pharmacies. Patients were questioned regarding the content and the degree of explanation in inhalation methods, the degree of understanding, and the degree of improvement in symptoms. For each point of explanation, the ratio of the score gap between (1) the patients’ evaluation (‘perception’) of the degree of the pharmacists’ explanation and pharmacists’ own evaluation of the degree of his/her own explanation, and (2) the patients’ evaluation of the degree of their own understanding and the pharmacists’ evaluation of the degree of patient understanding was calculated. We also verified the relationship between the patients’ evaluation and the degree of control of asthma attacks using a χ² test. We then reviewed the points of explanation which indicated significant difference, in an attempt to elucidate the characteristics of the patient-pharmacist “evaluation gap.”<Br><B>Results</B> The results indicated that the degree of explanation of the “objectives of using inhaled steroids,” and “how to cope with asthma attacks,” as well as the degree of understanding of the “objectives of using inhaled steroids,” “directions for use and dosage,” and “drug interactions” provided an important clue to controlling asthma attacks. Of special note was the existence of “a gap in evaluation (perception)” regarding the degree of explanation and understanding between the patients and the pharmacists for the “objectives of using inhaled steroids” and “how to cope with asthma attacks.”<br><B>Conclusions</B> It is crucial to pay special attention to the objectives of using inhaled steroids and how to cope with asthma attacks when guiding patients.
