Study: Antibiotic consumption up 46% in last two decades

November 17, 2021

The Global Research on Antimicrobial Resistance (GRAM) Project published a study in Lancet Planetary Health. As per study, global antibiotic consumption rates have increased by 46% in last two decades.

Key Points

GRAM used a novel approach, by deploying statistical modelling techniques.
It incorporated several data sources and types like large-scale household surveys in low-income & middle-income countries, antibiotic consumption data from World Health Organisation (WHO) and pharmaceutical sales data.
GRAM also gathered data from the European Centre for Disease Prevention and Control (ECDC).
GRAM study provides a comparative analysis of “antibiotic consumption rates” globally. This rate is defined in WHO metric of “defined daily doses (DDD) per 1000 population per day”.

Findings of the study

Variation in total antibiotic consumption rates, across the country, ranges from 5 DDD to 45.9 DDD per 1000 population per day.
In between 2000-2018, global antibiotic consumption rate increased by 46%, accounting for an increase from 9.8 to 14.3 DDD per 1000 population per day.
In low-income & middle-income countries, anti-biotic consumption rate increased by 76%, accounting an increase from 7.4 to 13.1 DDD per 1000 per day.
However, in high-income countries, consumption rates were stable.
Antibiotic consumption rates in South Asia increased by 116%.
Second largest increase (111%) was witnessed in North Africa and Middle East region.
