Insights
Childhood lower respiratory infections like bronchiolitis, RSV, and pneumonia are common. Incidence was highest among Native Hawaiian and Pacific Islander infants, indicating a need for targeted public health strategies.
Area of Science:
- Pediatric Infectious Diseases
- Epidemiology
- Public Health
Background:
- Lower respiratory tract infections (LRTI) are a major global cause of childhood hospitalization and mortality.
- Severe bronchiolitis, respiratory syncytial virus (RSV), and pneumonia represent significant pediatric LRTI burdens.
Purpose of the Study:
- To determine the incidence and epidemiology of severe bronchiolitis, RSV, and pneumonia in children under 5 years old in Hawaii.
- To identify demographic and temporal patterns of these infections within the Hawaiian pediatric population.
Main Methods:
- Retrospective analysis of Hawaii State Inpatient Database from 1997-2004.
- Inclusion criteria: Hawaii residents younger than 5 years diagnosed with bronchiolitis, RSV, or pneumonia.
Main Results:
- Average annual incidence rates per 1000 children under 5: bronchiolitis (3.8), RSV (2.7), pneumonia (6.8).
- Higher incidence in infants (<1 year), boys, and Native Hawaiian/other Pacific Islander children.
- Peak hospitalizations occurred October-February; estimated annual charges exceeded $11.5 million.
Conclusions:
- Overall incidence and hospitalization rates for these LRTI in Hawaii children were low compared to the general U.S. population.
- However, hospitalization rates for Native Hawaiian and other Pacific Islander children were significantly higher than other racial groups.
- Findings highlight disparities and suggest a need for culturally-tailored public health interventions.
Background:
Lower respiratory tract infections are a leading cause of hospitalization and mortality among children worldwide. Our objective was to describe the incidence and epidemiology of severe bronchiolitis, respiratory syncytial virus (RSV), and pneumonia among children in Hawaii.
Methods:
Retrospective analysis of the patient-linked hospital discharge data associated with bronchiolitis, RSV, and pneumonia among Hawaii residents younger than 5 years of age during 1997 through 2004 using the Hawaii State Inpatient Database.
Results:
During 1997 through 2004, the average annual incidence rates for bronchiolitis, RSV, and pneumonia were 3.8, 2.7, and 6.8 per 1000 children younger than 5 years, respectively. The incidence of each condition was higher for infants younger than 1 year (15.1, 9.8, and 15.9 per 1000 infants, respectively) than the incidence for children 1-4 years of age, and higher for boys compared with girls. The incidence of each condition was highest among Native Hawaiian and other Pacific Islander children compared with children of other race groups living in Hawaii. Most hospitalizations occurred during the months of October through February. Estimated median hospital charges were $4806 (bronchiolitis), $5465 (RSV) and $5240 (pneumonia), with overall average annual charges of $11.5 million.
Conclusion:
The incidence and hospitalization rates for bronchiolitis, RSV, and pneumonia among children younger than 5 years of age in Hawaii were low; the corresponding hospitalization rates were lower than those for the general U.S. population. However, the hospitalization rates for each condition among Hawaiian and other Pacific Islander children were much higher than those for other race groups or for the U.S. population.

Common Respiratory Disorders
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
