In 1997, SHEA and the Infectious Diseases Society of America published guidelines to prevent antimicrobial resistance arguing that "…appropriate antimicrobial stewardship, that includes optimal selection, dose, and duration of treatment, as well as control of antibiotic use, will prevent or slow the emergence of resistance among microorganisms."
The antimicrobial stewardship program will also provide pharmacists with the knowledge to educate patients that antibiotics will not work for a virus for example. [ 94 ] Excessive antimicrobial use has become one of the top contributors to the evolution of antimicrobial resistance.
Antimicrobial stewardship is the concept that healthcare providers should treat an infection with an antimicrobial that specifically works well for the target pathogen for the shortest amount of time and to only treat when there is a known or highly suspected pathogen that will respond to the medication.
An antimicrobial is an agent that kills microorganisms (microbicide) or stops their growth (bacteriostatic agent). [1] Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi. They can also be classified ...
Antibiotic inactivation: bacteria create proteins that can prevent damage caused by antibiotics, they can do this in two ways. First, inactivating or modifying the antibiotic so that it can no longer interact with its target. Second, degrading the antibiotic directly. [7] Multidrug efflux pumps: The use of transporter proteins to expel the ...
In 2014, the CDC officially recognized the need for antimicrobial stewardship within all U.S. hospitals in their publication of the Core Elements of Hospital Antibiotic Stewardship Programs. These programs outline opportunities for reducing unnecessary antibiotic usage, and provide guidelines for antibiotic prescription for common infections.
There was a marked rise in the consumption of antibiotics in the Watch category, while usage of certain antibiotics remained consistently high. These findings emphasized the imperative for vigilant antimicrobial stewardship to address evolving prescribing trends and combat resistance, thereby safeguarding patient health. [7]
Use the appropriate antimicrobial for an infection; e.g. no antibiotics for viral infections; Identify the causative organism whenever possible; Select an antimicrobial which targets the specific organism, rather than relying on a broad-spectrum antimicrobial; Complete an appropriate duration of antimicrobial treatment (not too short and not ...
