Knowledge, attitude and practice of antibiotics and their determinants in Eritrea: an urban population-based survey.

OBJECTIVE: To measure knowledge, attitude and practice of antibiotics and antibiotic resistance (ABR) and their determinants in the Eritrean urban population. DESIGN: A population-based, nation-wide, cross-sectional study. SETTING: Urban settings of Eritrea. PARTICIPANTS: Members of the general public aged ≥18 years and living in 13 urban places of Eritrea. Three-stage stratified cluster sampling was used to select the study participants. DATA COLLECTION AND ANALYSIS: Date were collected from July 2019 to September 2019 in a face-to-face interview using a structured questionnaire. The collected data were double entered and analysed using Census and Survey Processing system (V.7.0) and SPSS (V.23), respectively. Descriptive statistics, χ2 test, t-tests, analysis of variance, factorial analysis and multivariable logistic regression were performed. All analyses were weighted and p<0.05 was considered significant. PRIMARY AND SECONDARY OUTCOME MEASURES: Main outcome variables were knowledge, attitude and practice of antibiotics and ABR. Secondary outcome measure was the determinants of knowledge, attitude and practice. RESULTS: A total of 2477 adults were interviewed. The mean score of knowledge and attitude of antibiotics and ABR was 10.36/20 (SD=3.51, minimum=0 and maximum=20) and 22.34/30 (SD=3.59, minimum=6 and maximum=30), respectively. Of those who used antibiotics, the proportion of at least one inappropriate practice (use of antibiotics without prescription and/or discontinuation of prescribed antibiotics before completing the full course) was 23.8%. Young age <24 years (adjusted odds ratio (AOR)=1.61, 95% CI: 1.08 to 2.41), male sex (AOR=1.48, 95% CI: 1.14 to 1.91), higher level of education (AOR=1.76, 95% CI: 1.08 to 2.88), and negative attitude towards appropriate use of antibiotics (AOR=0.95, 95% CI: 0.92 to 0.97) were found to be the significant determinants of inappropriate practice of antibiotics. CONCLUSION: The gap in knowledge and inappropriate practice of antibiotics in the Eritrean urban population was widespread; requiring immediate attention from policy-makers and healthcare professionals.

Amoxicillin and Risk of Hearing Loss: Analysis of Reported Cases Submitted to the WHO Global Database.

BACKGROUND: Penicillins have never been associated with any form of hearing disorders. The Eritrean Pharmacovigilance Centre recently received two cases of hearing disorder (including one case of deafness) following the intake of amoxicillin capsules. This study was conducted to assess the causal link between amoxicillin and deafness. METHODS: Data mining was carried out in the WHO global database of individual case safety reports, VigiBase, and the Austin Bradford-Hill criteria were used to assess causality. RESULTS: A total of 94 cases of 'hearing disorders' related to amoxicillin were retrieved from VigiBase. Of these, 49 (52.1%) were reported as "deafness," and amoxicillin was marked as the sole suspected drug in 18 and the only drug administered in 13 cases. In the rest of the deafness cases (n=31), amoxicillin was concurrently administered with other drugs and reported as co-suspected. The median time to onset was three days and the outcome was marked as recovered (14), recovering (2), not recovered (16) and unknown (17). In five cases, deafness resolved following the withdrawal of amoxicillin. CONCLUSION: There appears a causal association between amoxicillin and hearing loss that requires further substantiation with better epidemiologic studies.
