AMR is a rapidly growing concern for public health globally. The development occurs when pathogens modify to survive despite the existence of medications designed to eliminate them, resulting in decreased treatment success, persistent infections, and increased risk related to medical procedures. The unnecessary consumption of antibiotics, self-medication, poor sanitation and other factors are significant contributors for accelerating AMR. To combat AMR requires coherent professional collaborations and population awareness for responsible healthcare practices. This help safeguard human health today and prepare the body adaptable for future medical processes.
What is Antimicrobial Resistance?
Antimicrobial resistance or AMR refers the natural resistance of microorganisms—bacteria, viruses, fungi, and parasites attains certain evolutions, leading to reduce the effect of drugs and medications which designated to destroy them. As a result, standard treatments become less effective or entirely ineffective, making persistent infections and increasing the risk of disease transmission.
Antimicrobials spectrum comprises numerous distinct classes of drugs.
These are categorized based on the type of microorganism they target:
- Antibiotics – treat bacterial infections
- Antivirals – used against viral diseases
- Antifungals – combat fungal infections
- Antiparasitics – target parasitic organisms
Causes of Antimicrobial Resistance
- Overprescription & Misuse
The overuse and misuse of antibiotics in healthcare are significant contributors to AMR, which is one of the top factors responsible for antimicrobial resistance. The occurrence of antibiotics for viral diseases like colds and flu indicates over-prescriptive behaviour when in actuality, antibiotics have no activity against viruses. Some broad-spectrum antibiotics are prescribed without diagnostic confirmation, hence they are provided unnecessarily.
Self-medication is also a major contributor to drug-resistant pathogens. Access to antibiotics without proper medical supervision in many countries has resulted in poor selection of appropriate antibiotics from a number of different products, resulting in patients receiving improper dosages of antibiotics and hence, unnecessary exposure to antimicrobials.
- Incomplete Courses
Patients should be counseled about the risk of taking fewer than the prescribed number of doses and to expect a symptomatic improvement from the therapy before the appropriate course of therapy has been completed (i.e., complete therapy). Patients continuing the treatment for only a few days because they feel better have allowed partially resistant bacteria to remain in their systems. A number of different types of microorganisms may also absorb and multiply from treatment in patients who terminate the treatment early. Incomplete therapy provides optimal conditions for the emergence of resistant microorganisms.
- Agricultural Use
The use of antimicrobial agents in agriculture and livestock production is an additional significant contributor to the development of antimicrobial resistance. Animal production has become a major market for antibiotics used to improve or prevent disease in enclosed environments, as well as for the routine use of antibiotics in animal production for growth promotion. Resistant organisms from animal Agriculture can be transmitted to humans via the manufacture of food, through water drainage systems and also through the environment.
- Poor Hygiene
The transmission of resistant microorganisms is facilitated by inadequate hygiene practices and critical shortcomings in the prevention of infection. For example, the use of contaminated medical devices, poor hand-washing by healthcare providers, the failure to sterilize medical devices and contaminated hands, and premature discharge of hospitalized patients into homes with insufficient supplies of healthcare can lead to the transmission of resistant organisms. Hospital and long-term care facilities are particularly susceptible to infections caused by residual hospital-acquired microorganisms because the majority of patients have compromised immune systems and require extensive antimicrobial therapy.
Prevention Strategies
In order to effectively combat antimicrobial resistance, a comprehensive system of prevention strategies must be integrated by collaborating with the various sectors including healthcare providers, public health organizations, governments, and patients.
- Rational use of antibiotics
Healthcare professionals must transition from rapid diagnosis to evidence-based prescription—conforming laboratory results about the effect and selective pressure of microbes—especially when dispensing antibiotics. Ideally used laboratory testing for guidance and following stewardship protocols for antimicrobial usage. Reducing or eliminating the use of unnecessary broad spectrum of antibiotics will reduce the potential risk of microbial resistance.
- Completing prescribed medication courses
Patients should be counseled to complete the full course of therapy as prescribed, even if they feel better before the end of the treatment course. Adhering to therapy promotes complete eradication of the infectious organism and reducing the chance that variants will develop.
- Vaccination to reduce infections
Vaccines play a significant role in the prevention of AMR by significantly reducing infection rates. Reducing infection rates eliminates primary illness, suppressing secondary infections, and the expensive vaccination coverage in turn decreases the incidence of resistance to antimicrobials.
- Improved hygiene and sanitation practices
Hygiene practice is a critical measure for eliminating infections and disease transmission. Proper handwashing with soap or hand wash, drink clean and safe water, safe food handling, appropriate sanitation systems, are all necessary elements to control the spread of resistant organisms.
- Infection control in hospitals
As healthcare facilities are a hotspot for AMR, they must adhere to strong infection prevention protocols and control practices such as necessary isolations for patients at risk of infectious disease transmission, following all protocols for routine sterility and employing surveillance programs to monitor and improve the quality of antimicrobial therapy.
- Public awareness and education
Public education regarding the appropriate use of antimicrobials is critical in preventing further development of AMR. Part of the public’s education should focus on the fact that antibiotics work only against infections caused by bacteria and that antibiotics should never be administered without the guidance of a qualified medical provider.
