Trends in the consumption of antibiotics in the Lebanese community between 2004 and 2016

Abstract

Background Antibiotic resistance has reached an alarming rate globally especially in middle-income countries such as Lebanon. The development of antibiotic resistance is strongly linked to the increased population’s injudicious consumption of antibiotics. Objective This study aims to explore the trends of antibiotics consumption in the Lebanese community, between 2004 and 2016, to inform rational use of antibiotics. Setting The study was performed using the Intercontinental Marketing Statistics (IMS) Health Lebanon database Method This is an observational longitudinal study conducted through a review of the IMS database. The annual antibiotics consumption was determined by the Defined Daily Dose (DDD)/1000 inhabitants/day (DID). The trends of antibiotics consumption were then categorized by antibiotic class and spectrum of activity. Main outcome measure The total consumption of antibiotics in Lebanon and the classes of antibiotics used by the community. Results Total community consumption of antibiotics, measured by DDD/1000 inhabitants/day (DID), significantly increased from 18.71 in 2004 to 31.26 in 2016. Penicillin combinations, quinolones, third-generation cephalosporins, tetracyclines, and carbapenems showed significant uptrends, in contrast to first-generation cephalosporins, sulfonamides and diaminopyrimidines, and beta-lactamase resistant penicillins. Broad-spectrum antibiotics showed a marked increase in their consumption from 11.50 DID in 2004 to 22.51 DID in 2016 whereas intermediate-spectrum antibiotics had only a slight increase in their consumption from 7.18 DID in 2004 to 8.51 DID in 2016, and narrow-spectrum antibiotics had a severe decline in their consumption from 0.006 DID in 2004 to 0.0003 DID in 2016. Conclusion There is an alarming increase in antibiotics consumption in Lebanon, particularly broad-spectrum antibiotics. This should be complemented with evidence on the determinants of antibiotic consumption such as prescriber and patient-related factors and drug promotional activities to minimize antibiotics overuse.
