Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

11.8K
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...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

4.2K
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.

Healthcare Associated Infections II: Preventive Measures

2.6K
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...

Infection

8.0K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

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

3.6K
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...

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

239
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Summary

External ventricular drain (EVD) infections are distinct from noninfectious ventriculitis, with different risk factors and onset times. Implementing chlorhexidine gluconate bathing significantly reduced EVD infection rates.

Area of Science:

  • Neurocritical care
  • Infectious disease
  • Neurosurgery

Background:

  • External ventricular drains (EVDs) are crucial for managing intracranial pressure but carry infection risks.
  • Differentiating EVD infection from noninfectious ventriculitis is challenging, often leading to empirical antibiotic overuse.
  • This study compares risk factors, predictors, prognosis, and intervention effectiveness for EVD infection versus noninfectious ventriculitis.

Discussion:

  • Noninfectious ventriculitis presents earlier (approx. 8 days post-EVD) and is linked to aneurysmal subarachnoid hemorrhage.
  • EVD infection typically manifests later (approx. 20 days post-EVD) and is associated with alcoholism and arteriovenous malformations.
  • Care bundle interventions, including chlorhexidine bathing, are effective in reducing EVD infection rates.

Key Insights:

  • Aneurysmal subarachnoid hemorrhage is a key predictor of noninfectious ventriculitis.
  • Alcoholism and arteriovenous malformations are significant risk factors for EVD infection.
  • Chlorhexidine gluconate bathing demonstrated a significant reduction in EVD infection rates from 3.6% to 1.0%.

Outlook:

  • Early identification of noninfectious ventriculitis can prevent unnecessary antibiotic use.
  • Targeted interventions for identified risk factors can further mitigate EVD infection.
  • Continued implementation and evaluation of care bundles are essential for optimizing EVD management.
