Objectives: To investigate antibiotic use in five national household surveys conducted with the WHO methodology to identify key determinants of antibiotic use in the community.
Methods: Data from The Gambia, Ghana, Kenya, Nigeria and Uganda surveys were combined. We used logistic regression models that accounted for the clustered survey design to identify the determinants of care seeking outside the home and antibiotic use for 2914 cases of recent acute illness.
Results: Overall, 95% of individuals with acute illness took medicines, 90% sought care outside their homes and 36% took antibiotics. In multivariate analyses, illness severity was a strong predictor of seeking care outside the home. Among those who sought outside care, the strongest predictor of antibiotic use was the presence of upper respiratory symptoms (OR: 3.02, CI: 2.36-3.86, P<0.001), followed by gastrointestinal symptoms or difficulty breathing, and antibiotics use was less likely if they had fever. The odds of receiving antibiotics were higher when visiting a public hospital or more than one healthcare facility.
Conclusions: The nature and severity of symptoms and patterns of care seeking had the greatest influence on decisions to take antibiotics. Antibiotics were widely available and inappropriately used in all settings. Policies to regulate antibiotics distribution as well as interventions to educate prescribers, dispensers and consumers are needed to improve antibiotic use.
