High frequency of antibiotic administration for COVID-19 patients in Syria and its associations with mortality and complications.
Observational study in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSyria’s healthcare system was severely challenged by the COVID-19 pandemic due to resource scarcity and a shortage of healthcare personnel. In this context, antibiotics were frequently prescribed empirically because of limited diagnostic capacity, concerns about secondary bacterial infections, and delayed hospitalization, despite the limited evidence of bacterial co-infection among patients with COVID-19.
methodThis study investigates the use of antibiotics among hospitalized COVID-19 patients in Syria, focusing on its association with mortality, ICU admissions, and complications. We conducted a multicenter retrospective cohort study in the four major Syrian cities, including 3199 patients, 93.4% of whom received antibiotics.
resultsThe most frequently prescribed antibiotics were cephalosporins, macrolides, and quinolones. We found a significant association between the administration of multiple classes (> 3) of antibiotics and increased mortality and ICU admissions, even after adjusting for the LR-COMPAK mortality risk score and treating hospital. Specifically, the use of carbapenem, piperacillin/tazobactam, glycopeptides, and cephalosporins were independently linked to increased mortality, while piperacillin/tazobactam, carbapenem, glycopeptides, amoxicillin/clavulanate, cephalosporins, and quinolones were associated with ICU admissions. Administration of multiple classes (> 3) of antibiotics also correlated with complications including secondary infections, septic shock, and acute kidney injury.
conclusionsThis study highlights excessive antibiotic use among hospitalized COVID-19 patients in Syria and its association with increased mortality, ICU admission, and serious complications. These findings underscore the urgent need for strengthened antibiotic stewardship and improved prescribing practices to reduce adverse outcomes and mitigate the growing threat of antimicrobial resistance in conflict-affected and resource-limited healthcare settings.
