Healthcare Associated Infections II: Preventive Measures01:22

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...

Endocarditis III: Medical Management

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

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...

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...
Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic01:26

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...
Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

Area of Science:

  • Microbiology
  • Dental Public Health
  • Biomedical Engineering

Background:

  • Dental chair units utilize dental unit waterlines (DUWLs) for water delivery, crucial for instrument cooling and irrigation.
  • These DUWLs are susceptible to microbial proliferation and biofilm formation due to their narrow-bore plastic tubing.
  • Water quality is paramount as dental teams and patients are exposed to water and aerosols.

Purpose of the Study:

  • To present the current knowledge on microbial contamination of DUWLs.
  • To emphasize the infectious risks associated with contaminated DUWLs.
  • To review various disinfection and protection methods for DUWLs.

Main Methods:

  • Literature review of studies on microbial contamination in dental unit waterlines.
  • Analysis of data regarding microbial densities and types found in DUWLs.
  • Evaluation of existing disinfection protocols and protective measures.

Main Results:

  • DUWLs create a favorable environment for microbial growth and biofilm development.
  • Water delivered through DUWLs is frequently contaminated with high levels of bacteria, fungi, protozoa, and viruses.
  • Microbial contamination poses a potential health risk, particularly for immunocompromised individuals.

Conclusions:

  • Microbial contamination of DUWLs is a significant concern in dental settings.
  • Understanding the infectious risk is crucial for implementing effective control measures.
  • Various strategies exist for disinfecting and protecting DUWLs to ensure water safety.
