Multiple times a day at the AdventHealth Orlando laboratory, we see multi-drug resistant (MDR) bacteria isolated, identified and categorized based on their resistance profile. Sadly, the most vulnerable patients (although not the only ones) are the ones battling against these organisms.
These MDRs, are typically bacteria or fungi that have developed resistance to one or more types of antimicrobials, which are key to combat them. Examples such as Methicillin-Resistant Staphylococcus aureus (MRSA), which has been named a superbug and beta-lactams resistant Streptococcus pneumoniae (commonly known as pneumonia and meningitis) are often encountered in our laboratory. MDR classification is part of our microbiological report to alert healthcare providers to the presence of these challenging organisms.
PHYSICIAN TAKEAWAY:
Microbiologists provide clinically rational analysis of these organisms and their antimicrobial profile for therapeutic and epidemiological purposes to infectious diseases physicians, preventionists and pharmacists. This is my priority and contribution to fight the AMR crisis. Physicians can help in the fight by taking immediate action to create awareness and recognize AMR as a looming global medical issue.
GLOBAL IMPACT:
The world is already experiencing the economic impact on the health care system, which is significant, and it does not seem to slow down as crucial medicines are becoming ineffective. The CDC estimated that the cost of AMR is $55 billion every year in the United States, $20 billion for health care and about $35 billion for loss of productivity.
Although multiple causes are contributing to the rise of AMR, the high use of antimicrobials in the farming industry and the overuse of antimicrobials in the clinical setting are two of the main culprits.
WAYS TO TACKLE ANTIMICROBIAL RESISTANCE:
A 2016 review on AMR that economist Jim O’Neill presented to the United Kingdom’s prime minister, summarizes solutions to tackle this problem globally.
To positively affect the current landscape of infectious diseases, especially AMR, a microbiologist’s expertise can be a valuable resource for other physicians by incorporating two main approaches in the lab:
- Clear definition of MDR: Our clinical and epidemiological expertise in multidrug resistance (MDR) organisms along with our ability to identify, understand and classify them allows us to develop rapid detection algorithms, additional antimicrobial testing guidelines and rapid communication protocols to circumvent the crisis.
- Direct case intervention: Our clinical review of significant MDR cases, including an analysis of the organism’s resistance pattern, additional antimicrobial testing, and treatment is paramount for giving infectious diseases providers added context in real-life situations to offer actionable therapeutic information in difficult to treat cases.
By finding innovative ways to work in tandem with primary-care physicians, who are on the frontline of prescribing medicine, we can prevent this drug-resistant crisis.
With the ever-growing threat of antibiotic resistance, microbiologists are indispensable to the health care ecosystem. Not only can we unravel potential vulnerabilities of microscopic pathogens, but microbiologists can develop innovative strategies to combat them.
In collaboration with primary-care physicians, who serve as the first line of defense in prescribing medicine, we can stand together against this drug-resistant crisis. By fostering an integrated approach, combining the meticulous investigative skills of microbiologists with the practical therapeutic acumen of clinicians, the battleground of antimicrobial resistance can be transformed, and the playing field levelled in this battle to save lives.
