Drivers of inappropriate antibiotic use in low- and middle-income countries

Abstract

Antimicrobial resistance (AMR) is a global security threat that accounts for about 700 000 deaths annually. Studies have shown that antimicrobial resistance could result in a 2% to 3.5% reduction in global Gross Domestic Product by 2050 and a loss of between 60 and 100 trillion US dollars, worth of economic output resulting in significant and widespread human suffering. Low- and middle-income countries (LMICs) will be worse hit by an unchecked rise of AMR. For example, it is predicted that AMR could kill about 4.1 million people in Africa by 2050 if it is not curbed. Similarly rising rates of AMR will lead to increased treatment costs and an inability to attain universal health coverage, in LMICs with fragile health systems. Sadly, AMR is driven by the inappropriate use of antimicrobials, especially antibiotics. Inappropriate antibiotic use is a pertinent problem in LMICs where regulatory frame works are weak. Inappropriate antibiotic use in LMICs is a multifaceted problem that cuts across clinical and veterinary medicine and agriculture. Therefore, efforts geared at curbing inappropriate antibiotic use in LMICs must identify the factors that drive this problem (i.e. inappropriate antibiotic use) in these countries. A clear knowledge of these factors will guide effective policy and decision making to curb inappropriate antibiotic use and ultimately AMR. The focus of this review is to discuss the factors that drive inappropriate antibiotic use in LMICs.
