Insights

Children with asthma and allergic rhinitis experience more hospitalizations and longer stays. This highlights the importance of managing allergic rhinitis in pediatric asthma patients to reduce healthcare resource use.

Area of Science:

  • Pediatric Pulmonology
  • Allergy and Immunology
  • Health Services Research

Background:

  • Inadequately controlled allergic rhinitis is linked to increased asthma exacerbations and poorer symptom control in asthmatic patients.
  • This can lead to higher medical resource utilization.
  • Understanding this association is crucial for effective asthma management.

Purpose of the Study:

  • To assess the impact of co-occurring allergic rhinitis on asthma-related hospital resource utilization in children under 15 in Norway.
  • To quantify the relationship between allergic rhinitis and hospital admissions and days among pediatric asthma patients.

Main Methods:

  • Population-based retrospective cohort study using national hospital admission data (1998-1999).
  • Included children aged 0-14 years with asthma.
  • Multivariate regression models (linear and Cox proportional-hazards) analyzed associations with hospital days and readmission hazards, adjusting for covariates.

Main Results:

  • Out of 2961 asthmatic children, 795 (26.8%) had a history of allergic rhinitis.
  • Asthmatic children with allergic rhinitis showed a 1.72-times greater hazard of asthma-related readmissions.
  • Concomitant allergic rhinitis predicted a significant increase in hospital days per year (0.23 days, P < 0.05).

Conclusions:

  • Concomitant allergic rhinitis in asthmatic children is significantly associated with increased asthma-related hospital readmissions.
  • The presence of allergic rhinitis also predicts a greater total number of hospital days.
  • Integrated management of allergic rhinitis may reduce healthcare burden in pediatric asthma.

Asthma-I: Introduction01:29

Asthma-I: Introduction

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma-III: Symptoms and Complications01:24

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
Asthma III: Clinical Manifestations01:13

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
