Antibiotic Resistance

The evolution of pathogens to resist the drugs used to treat infections is an ongoing threat to public health, animal health, food production, and national security. Globally, a recent analysis estimated that 1.2 million deaths were caused by antibiotic-resistant (AR) bacteria in 2019, making this threat a leading cause of death for people of all ages worldwide.

Development of novel antimicrobials has slowed, and the preclinical and clinical pipeline is likely to be insufficient to support current and future patient needs.

The market for antimicrobial (AM) drugs is unique in that it is associated with a positive externality (public health) as well as a negative externality (antimicrobial resistance, or AMR) (Mossialos, et al., 2010). AMR occurs when microbes change over time and no longer respond to available medicine.

It is well known that antimicrobial resistance (AMR) creates a substantial and ongoing public health and economic burden and understanding the size and nature of this burden is important for the ability to respond to the threat of AMR. However, estimating or projecting that burden within the U.S.

In 2017, at least 2.8 million people in the U.S. acquired serious infections with bacteria that are resistant to one or more antimicrobial drugs and 35,000 have died as a result. Resistance to antimicrobials is viewed as a global threat with antimicrobial drug use in human and animal health driving resistance.

Pathogens that have evolved to be resistant to the drugs currently used to treat infections are an ongoing threat to public health, animal health, food production, and national security. Globally, a recent analysis estimated that 1.2 million deaths were caused by antibiotic-resistant (AR) bacteria in 2019, making this threat a leading cause of death for people of all ages worldwide.

Objectives: Clinical guidelines or guidance is an important tool for preventing and treating antimicrobial-resistant (AMR) infections. We sought to understand and support the effective use of guidelines and guidance for AMR infections.

The National Action Plan for Combating Antibiotic-Resistant Bacteria 2015 – 2020 (2015 Plan) has guided the U.S. Government’s response to combating antibiotic-resistant infections since its establishment in 2015. The U.S. Government’s Interagency Task Force for Combating Antibiotic-Resistant Bacteria (CARB) has produced four previous reports on progress toward the 2015 Plan.

COVID-19 has impacted antimicrobial drug prescribing both directly, through COVID-19 treatment, and indirectly, through the reduced spread of illnesses for which antimicrobial drugs are commonly prescribed.

The National Action Plan for Combating Antibiotic-Resistant Bacteria (CARB), 2020-2025, presents coordinated, strategic actions that the United States Government will take in the next five years to improve the health and wellbeing of all Americans by changing the course of antibiotic resistance. This Plan is based on the U.S.
