    The use of antibiotics to prevent infections during pregnancy and the puerperium is clearly different from the use of antibiotics to treat established infections. Prophylactic antibiotics are frequently prescribed on an "empiric" basis, which for many years was thought to have few adverse consequences. Concerns about the emergence of resistant strains of common bacteria, in addition to the emergence of strains with increased virulence, have resulted in increased scrutiny of the use of antibiotics, particularly in the hospital setting. Cost considerations also affect the use and choice of prophylactic agents. The purpose of this Practice Bulletin is to present a review of clinical situations in which prophylactic antibiotics are frequently prescribed and to weigh the evidence supporting the use of antibiotics in these scenarios.

    Healthcare Associated Infections II: Preventive Measures

    Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
    The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

    Standard Precaution

    Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
    Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

    Transmission-based Precautions I: Contact, Enteric, and Droplets

    Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
    Contact Precautions:
    Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

    Development of the Oral Microbiota

    The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

    Transmission-based Precautions II: Airborne and Protective Environment

    Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
    Airborne precautions:
    Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

    Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

    A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
