Healthcare Associated Infections II: Preventive Measures01:22

Healthcare Associated Infections II: Preventive Measures

3.5K
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 Precaution01:26

Standard Precaution

2.7K
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 II: Airborne and Protective Environment

1.8K
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...

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

4.4K
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...

Hand hygiene01:23

Hand hygiene

5.4K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

692
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Summary

Optometry clinics in Los Angeles County show suboptimal infection prevention practices, including poor hand hygiene and inconsistent use of personal protective equipment. These findings highlight critical areas for improvement to prevent disease transmission in eye care settings.

Area of Science:

  • Public Health
  • Infectious Disease Epidemiology
  • Ophthalmology Infection Control

Background:

  • An outbreak of epidemic keratoconjunctivitis linked to adenovirus in Los Angeles County optometry clinics highlighted potential gaps in infection control.
  • Suboptimal infection prevention practices were identified in the clinic associated with the outbreak.

Purpose of the Study:

  • To assess and determine the current infection prevention practices employed in optometry clinics across Los Angeles County.

Main Methods:

  • A survey comprising 17 questions on infection prevention was distributed to optometry providers in Los Angeles County.
  • The survey was administered through email lists and in-person at a continuing education event for optometrists.
  • Results were analyzed and presented as percentages.

Main Results:

  • A significant portion of respondents lacked written hand-hygiene policies (58.5%) and did not use gloves when examining patients with eye drainage (46.2%).
  • Nearly half of practices (48.6%) did not implement droplet precautions for patients with respiratory symptoms.
  • Issues were also noted in the handling of multidose eye-drop vials and tonometer disinfection, with many not discarding contaminated vials or using inadequate disinfection methods.

Conclusions:

  • The study identified significant concerns regarding the adherence to standard and transmission-based precautions in optometry clinics.
  • Key areas needing improvement include hand hygiene policy enforcement, appropriate use of personal protective equipment, consistent discarding of contaminated eye-drop vials, and tonometer disinfection techniques.
