Abstract

Background: Antimicrobials have revolutionized medicine globally, but emerging antimicrobial resistance due to antimicrobial misuse might revert the world to the "pre-antibiotic era". Research on the topic contributes to fighting antimicrobial resistance and developing related strategies. Hence, this bibliometric analysis aimed to assess antimicrobial research productivity in Lebanon.

Methods: Relevant publications were retrieved from PubMed, and data were assessed using the VOS viewer. The most research-active institutions, collaboration patterns, and various antimicrobial research areas were reported and discussed.

Results: Research productivity has exhibited an increasing trend over the past 20 years. Private institutions were the most active (90%), while international collaborations were moderate (40%), mainly with institutions in the United States and France. The only visible public-private partnership involved collaboration between the Lebanese University and other institutions. While immunology and molecular biology-related keywords were frequently used before 2012, more clinical (treatment outcome, antimicrobial stewardship, antimicrobial resistance) and environmental cluster-related keywords appeared later, with a low occurrence of resistance and the One Health concept.

Conclusion: This study assessed research productivity related to antimicrobials from Lebanese institutions; it showed the need for greater public sector involvement, expanded national and…
