Efficacy and Safety of Different Colistin Administration Routes for Nosocomial Pneumonia Caused by Carbapenem-Resistant Organisms: A Single Centre, Open Label, Prospective Cohort Study [Letter]
Abstract
The article titled “Efficacy and Safety of Different Colistin Administration Routes for Nosocomial Pneumonia Caused by Carbapenem-Resistant Organisms: A Single Centre, Open Label, Prospective Cohort Study” has caught our attention. This article discusses the clinical challenges arising in an era of rising microbial resistance, specifically evaluating the role of inhaled antibiotic therapy in the management of carbapenem-resistant infections in critically ill patients. Wei et al used multiple treatment groups (intravenous (IV), inhaled (IH), and combined IV+IH colistin therapies for carbapenem-resistant Gram-negative bacterial pneumonia), thereby enabling a more comprehensive evaluation of therapeutic strategies in real-world settings. Utilizing longitudinal clinical indicators, such as inflammatory biomarkers and oxygenation indices, enhances the reliability of outcome assessments and fosters a more dynamic understanding of treatment responses. 1 This study aligns with existing concerns regarding antimicrobial resistance, as previously demonstrated by research using genomic studies and resistance profiles. This study demonstrates the complexity of pathogens resistant to various drugs, particularly carbapenems, and highlights the need for maximized therapeutic approaches. 2 However, it is important to acknowledge certain limitations. The study’s single-center design and the absence of randomization may introduce potential selection bias, thereby restricting the…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
