    Study Notes

    Antimicrobials

    • Antimicrobials include antibiotics, antivirals, antifungals, and antiparasitics.
    • These medications are used to prevent and treat infections in humans, animals, and plants.

    Antimicrobial Resistance (AMR)

    • AMR occurs when pathogens evolve and no longer respond to antimicrobial treatments, complicating infection control.
    • Drug resistance increases the severity and spread of infections, leading to more severe illness and higher mortality rates.

    Importance of Antibiotics

    • Approximately half of hospitalized patients receive antimicrobials, particularly in ICUs and NICUs.
    • Antibiotics are critical for life-saving treatments in serious infections, such as sepsis.

    Issues with Antibiotic Use

    • Patients often misuse antibiotics without understanding proper therapy principles.
    • Medical practitioners may feel pressured to prescribe antibiotics for immediate relief, leading to inappropriate use.
    • Prolonged antibiotic use post-surgery and unnecessary treatment of viral infections are common practices.

    Role of Microbiology Lab

    • Responsible for correct specimen testing and species identification.
    • Conducts antimicrobial susceptibility testing (AST) and interprets AST reports accurately.
    • Provides guidance on appropriate antimicrobial choice based on results.

    Strategies to Prevent AMR

    • Stop antimicrobial treatment when infections are cured or cultures are negative.
    • Isolate pathogens to prevent patient-to-patient transmission using standard infection control measures.
    • Break the chain of infection by maintaining hand hygiene and containing contagions.

    Antimicrobial Stewardship Program (ASP)

    • ASP teams include diverse professionals: infectious disease physicians, infection control practitioners, microbiologists, clinical pharmacists, and hospital epidemiologists.
    • Focus on education and intervention to improve prescribing practices and utilize local resistance patterns.

    Supplemental Stewardship Strategies

    • Develop guidelines incorporating local microbiological data.
    • Implement automatic stop functions for antibiotic orders and optimize dosing based on patient-specific factors.
    • Encourage switching from intravenous to oral therapy when appropriate to reduce hospital stays.

    Process and Outcome Measure Indicators

    • Compliance with treatment guidelines is monitored by comparing the number of patients receiving appropriate empirical treatments.
    • The effectiveness of stewardship is evaluated by tracking days of therapy (DOT) per 1000 patient-days.

    Antibiotic Awareness Week

    • Established by WHO in 2015 to promote responsible use of antibiotics and raise awareness about antibiotic resistance.
    • Encourages health professionals to analyze prescribing patterns and engage in education to change behaviors regarding antibiotic use.

    Methicillin-Resistant Staphylococcus Aureus (MRSA)

    • MRSA is a strain of Staphylococcus aureus resistant to methicillin and other penicillin-related antibiotics.
    • Historically, penicillin was initially effective, but resistance grew due to the production of β-lactamase.

    Types of MRSA Infections

    • Hospital-acquired MRSA (HA-MRSA) and community-associated MRSA (CA-MRSA) are the two primary types.

    Prevention of HA-MRSA

    • Implement contact isolation for patients with MRSA infections.
    • Use proper hand hygiene and personal protective equipment (PPE) for staff and visitors.
    • Regular environmental cleaning is essential to mitigate MRSA survival on surfaces and objects.
