Antimicrobial use for influenza-like illnesses in Nha Trang, Vietnam: a cross-sectional study.
Observational study in BMJ open, 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
objectivesThis study aimed to investigate the characteristics and management of influenza-like illnesses (ILIs) in the outpatient and inpatient settings in Vietnam.
designA cross-sectional, observational study. SETTING AND
participantsWe conducted a questionnaire survey of 407 individuals with ILI symptoms who presented to public community health centres and the paediatric ward of a public hospital in the city of Nha Trang, Khanh Hoa Province, Vietnam, from December 2022 to March 2023.
interventionsNot applicable. PRIMARY AND SECONDARY OUTCOME MEASURES: No primary and secondary outcomes were pre-specified because this study was an explanatory study. The basic characteristics of the participants are presented using descriptive statistics. We conducted multivariable logistic regression analysis to examine the factors associated with the prescription of antibiotics to outpatients with ILIs.
resultsA total of 198 outpatients and 200 inpatients were enrolled in the study. Most inpatients were children under 5 years of age and experienced longer illness durations and higher costs, with almost all patients receiving antibiotics. The rate of antimicrobial prescription for ILIs was 79.3% for outpatients and 99.5% for inpatients. The median health-related quality of life score of participants aged ≥18 years during illness was 0.796 (IQR 0.674-0.922). Logistic regression analysis indicated a negative association between a definite diagnosis of viral infection by rapid diagnostic test and outpatient antibiotic prescription (OR: 0.20, p=0.006).
conclusionsThis study underscores the widespread inappropriate antimicrobial use for ILIs in a community in Vietnam, which contributes to an avoidable economic and health burden. The results of this study suggest that implementing diagnostic tools may support antimicrobial stewardship efforts.
