Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

12.3K
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...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

40
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...

Healthcare Associated Infections II: Preventive Measures

2.8K
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...

Urinary Tract Infection II: Pathophysiology

46
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Acute Pyelonephritis II: Diagnostic Studies and Management

41
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Area of Science:

  • Neurosurgery
  • Infectious Disease Epidemiology
  • Patient Safety

Background:

  • Lumbar drains (LDs) are crucial for cerebrospinal fluid (CSF) diversion in neurosurgery.
  • Infection following LD insertion is a serious complication, leading to increased morbidity.
  • Understanding risk factors is vital for preventing LD-associated infections.

Purpose of the Study:

  • To evaluate the incidence and etiology of lumbar drain infections.
  • To identify risk factors associated with LD infections across multiple neurosurgical units.
  • To inform strategies for reducing infection rates in patients with LDs.

Main Methods:

  • Retrospective multicenter cohort study of adult patients requiring LDs (January 2009 - February 2024).
  • Analysis of demographic, clinical, and microbiological data.
  • Multivariate logistic regression used to identify significant risk factors for LD infection.

Main Results:

  • Overall LD infection rate was 11.4% (116/1017 patients).
  • Significant risk factors included preoperative oral steroid use, prolonged drain duration, out-of-hours surgery, and CSF leaks.
  • Factors reducing risk included insertion during primary surgery and specific reasons for insertion.

Conclusions:

  • This study provides a comprehensive analysis of factors influencing LD infections in a large neurosurgical patient cohort.
  • Recommendations include prioritizing LD insertion during primary surgery and minimizing drain duration.
  • Prompt removal of disconnected drains and avoiding unnecessary sampling are key to infection prevention.
