ANTIMICROBIAL RESISTANCE (AMR)

Jan. 20, 2022

Hundreds of thousands of deaths occur today due to previously treatable infections — such as lower respiratory and bloodstream infections — because the bacteria that cause them have become resistant to treatment.

About:

  • A comprehensive estimate of the global impact of antimicrobial resistance (AMR), covering 204 countries and territories and published in The Lancet, has found that 1.27 million people died in 2019 as a direct result of AMR, which is now a leading cause of death worldwide, higher than HIV/AIDS or malaria.

  • The Global Research on Antimicrobial Resistance (GRAM) report used statistical modelling to estimate deaths linked to 23 pathogens and 88 pathogen-drug combinations.

  • Apart from 12.7 lakh deaths caused directly by AMR (these would not have occurred had the infections been drug-susceptible), another 49.5 lakh deaths were associated with AMR (a drug-resistant infection was implicated, but resistance itself may or may not have been the direct cause of death).

  • HIV/AIDS and malaria were estimated to have caused 8.6 lakh and 6.4 lakh deaths respectively in 2019.

  • Of the 23 pathogens studied, drug resistance in six (E coli, S aureus, K pneumoniae, S pneumoniae, A baumannii, and P aeruginosa) led directly to 9.29 lakh deaths and was associated with 3.57 million.

  • One pathogen-drug combination – methicillin-resistant S aureus, or MRSA – directly caused more than 1 lakh deaths.

  • Resistance to two classes of antibiotics often considered the first line of defence against severe infections – fluoroquinolones and beta-lactam antibiotics – accounted for more than 70% of deaths caused by AMR.
