Effectiveness of amoxicillin and amoxicillin-clavulanate for the treatment of community-acquired pneumonia in adults and children: a systematic review and meta-analysis
Abstract
Abstract Introduction Community-acquired pneumonia (CAP) is a key contributor to the global burden of morbidity and mortality, and it drives large volumes of antibiotic use. Despite widespread recommendation to use amoxicillin for treatment, there are concerns of its effectiveness as empirical antibiotics for CAP. The aim of this study is to evaluate existing evidence on the effectiveness of amoxicillin and amoxicillin-clavulanate for CAP in children and adults. Methods We systematically searched PubMed, Cochrane Library, Web of Science, and Ovid-MEDLINER with no language restrictions for randomized controlled trials published until July 16, 2024 comparing the effectiveness of amoxicillin or amoxicillin-clavulanate versus other antibiotics or placebo with a primary outcome of clinical resolution or clinical failure. We used a random effects and a fixed effects logistic regression model to estimate the pooled treatment effect size. We performed a network meta-analysis for the indirect comparison between amoxicillin and amoxicillin-clavulanate. Results We extracted data from 44 studies including 45,400 patients. We found no strong evidence of a differential effect on clinical resolution when comparing amoxicillin to other antibiotics (n=15 trials, pooled odds ratio [OR]: 0.88; 95% confidence interval [CI]: 0.56-1.38) or amoxicillin-clavulanate to other antibiotics (n=17 trials, OR: 0.89 [95%: 0.76-1.04]). Similarly, no evidence on difference in clinical failure between…
How strong is the evidence?
Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid. Reported size: 45,400 participants or records.
