Insights

Pediatric patients with healthcare-associated laboratory-confirmed influenza (HA-LCI) were studied. Asthma emerged as a significant independent risk factor for HA-LCI in hospitalized children.

Area of Science:

  • Pediatric Infectious Diseases
  • Hospital Epidemiology
  • Respiratory Illnesses

Background:

  • Healthcare-associated infections (HAIs) pose a significant threat to hospitalized patients, particularly vulnerable pediatric populations.
  • Influenza, a common respiratory illness, can lead to severe complications and prolonged hospital stays.
  • Understanding the specific risk factors for healthcare-associated laboratory-confirmed influenza (HA-LCI) in children is crucial for targeted prevention strategies.

Purpose of the Study:

  • To characterize the clinical features and outcomes of pediatric patients diagnosed with HA-LCI.
  • To identify independent risk factors associated with the development of HA-LCI in hospitalized children.

Main Methods:

  • A case-control study was conducted involving 46 hospitalized pediatric patients with confirmed HA-LCI.
  • Data collected included clinical exposures in the three days preceding symptom onset.
  • Multivariate analysis was employed to identify independent risk factors.

Main Results:

  • No significant differences in clinical exposures were found between cases and controls in the 3 days prior to HA-LCI onset.
  • Asthma was identified as an independent risk factor for HA-LCI in the studied pediatric population.
  • The odds ratio for asthma as a risk factor was 3.49 (95% confidence interval, 1.25-9.75).

Conclusions:

  • Asthma is a significant independent risk factor for developing healthcare-associated laboratory-confirmed influenza in hospitalized children.
  • Further research into preventative measures for pediatric influenza in hospital settings, especially for asthmatic children, is warranted.
  • Enhanced surveillance and infection control protocols may be necessary for high-risk pediatric groups.

Influenza

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...

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...
Pneumonia I: Introduction01:30

Pneumonia I: Introduction

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...
Pneumonia I: Introduction01:29

Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...

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...
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...
