Assessment of medication knowledge among patients with asthma

Abstract

Abstract Objectives Asthmatic patient's knowledge about their treatment can affect asthma control and adherence level. This study investigated the level of medication knowledge, the level of adherence and factors affecting both knowledge and adherence in adult patients with asthma. Methods A cross-sectional study was carried out in Jordan between 2017 and 2018. A face-to-face interview was conducted by a clinical pharmacist with asthma patients attending hospital pharmacies for refilling their prescriptions. Key findings A total of 218 adults with asthma were included into the study and 60.6% were knowledgeable about their medications. University degree education (OR = 3.67; P value < 0.001), positive family history of asthma (OR = 1.89; P value = 0.04) and longer asthma duration (OR = 1.03; P value = 0.049) were significantly associated with a high medication knowledge. On the other hand, married participants were less knowledgeable than single ones (OR = 0.30; P value = 0.041). High medication knowledge score (OR = 4.76, P value = 0.008), older age (OR = 1.06, P value = 0.004) and male gender (OR = 3.82, P value = 0.01) were significant predictors of high medication adherence. Conclusions These findings highlight the importance of educational programmes that should be conducted in primary healthcare settings, such as community pharmacies, where pharmacists should educate patients about their medication and the importance of adherence.
