Wrong diagnosis - Wrong antimicrobials: Rise in antimicrobial resistance in developing countries

Antimicrobial resistance (AMR) is a growing global health crisis, disproportionately affecting developing countries. A key driver is the chain of wrong diagnosis leading to inappropriate antimicrobial use. Misclassification of infections-such as viral illnesses mistaken for bacterial infections-and failure to identify infection sources needing drainage or debridement result in unnecessary or ineffective antimicrobial therapy. This accelerates AMR, compels reliance on high-end antimicrobials, and fosters emergence of extensively drug-resistant pathogens. Compounding factors include sample contamination, absence of diagnostic-laboratory feedback loops, and empirical therapy without microbiological confirmation. Together, these perpetuate a vicious cycle of diagnostic error and AMR escalation. Strengthening diagnostic accuracy through point-of-care testing, molecular diagnostics, source control measures, and integration of diagnostic stewardship into antimicrobial stewardship programs is critical. Policy reforms, clinician education, and adoption of digital health innovations can support these efforts, breaking the cycle and preserving antimicrobial efficacy in resource-limited settings.
