‘’Myth Busting in Infectious Diseases’’: A Comprehensive Review

TL;DR

This paper reviews and debunks common myths in infectious diseases, such as the belief that bactericidal antibiotics are always better and that longer antibiotic use prevents resistance.

Contribution

The paper provides a comprehensive review challenging long-held misconceptions in clinical antibiotic use with evidence from recent studies.

Findings

Bacteriostatic antibiotics can be as effective as bactericidal ones for certain infections.

Ordering urine cultures indiscriminately leads to unnecessary antibiotic prescriptions.

Extended antibiotic therapy does not prevent resistance and may be harmful.

Abstract

Antibiotics have played a pivotal role in modern medicine, drastically reducing mortality rates associated with bacterial infections. Despite their significant contributions, the emergence of antibiotic resistance has become a formidable challenge, necessitating a re-evaluation of antibiotic use practices. The widespread belief in clinical practice that bactericidal antibiotics are inherently superior to bacteriostatic ones lacks consistent support from evidence in randomized controlled trials (RCTs). With the latest evidence, certain infections have demonstrated equal or even superior efficacy with bacteriostatic agents. Furthermore, within clinical practice, there is a tendency to indiscriminately order urine cultures for febrile patients, even in cases where alternative etiologies might be present. Consequently, upon obtaining a positive urine culture result, patients often receive antimicrobial prescriptions despite the absence of clinical indications warranting such treatment. Furthermore, it is a prevailing notion among physicians that extended durations of antibiotic therapy confer potential benefits and mitigate the emergence of antimicrobial resistance. Contrary to this belief, empirical evidence refutes such assertions. This article aims to address common myths and misconceptions within the field of infectious diseases.
