Insights
Respiratory syncytial virus (RSV) bronchiolitis was the leading cause of infant hospitalizations between 1997 and 1999. This study details the hospitalization rates and trends for infants diagnosed with RSV.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Recent data on infant hospitalizations for respiratory syncytial virus (RSV) have been lacking.
- Understanding RSV's impact on infant health is crucial for public health initiatives.
Purpose of the Study:
- To determine the incidence and rate of infant hospitalizations with a diagnosis of respiratory syncytial virus (RSV).
- To analyze trends and identify peak hospitalization periods for RSV in infants.
Main Methods:
- Retrospective analysis of the National Hospital Discharge Survey data from 1997 to 1999.
- Inclusion criteria: infants under 1 year old with RSV-coded diagnoses (ICD-9-CM 466.11, 480.1, 079.6).
- Hospitalization rates were calculated using annual Census data.
Main Results:
- RSV bronchiolitis was the primary diagnosis for infants hospitalized annually.
- A total of 297,684 infant discharges with RSV diagnoses were recorded between 1997 and 1999.
- The hospitalization rate was 25.2 per 1,000 infants, with peak admissions in February.
Conclusions:
- RSV bronchiolitis was identified as the leading cause of hospital admissions for infants under one year of age.
- The findings highlight the significant burden of RSV on infant healthcare utilization.
- Data underscore the need for continued surveillance and prevention strategies for RSV in infants.
Background:
The recent number and rate of infant hospitalizations with a respiratory syncytial virus (RSV)-coded diagnosis have not been published.
Methods:
Retrospective data analysis. National Hospital Discharge Survey data for 1997 to 1999 were analyzed for discharges of infants < 1 year old with an RSV-coded diagnosis (ICD-9-CM 466.11, 480.1, 079.6). Hospitalization rates were estimated with annual midyear Census data.
Results:
RSV bronchiolitis was the leading primary diagnosis annually for all infants hospitalized for any reason. Between 1997 and 1999, 297 684 RSV-coded discharges of infants with an RSV-coded diagnosis occurred. The associated hospitalization rate was 25.2 per 1000 infants. RSV-coded discharges peaked in February.
Conclusion:
RSV bronchiolitis was the leading cause of hospital admissions of infants younger than age 1 year for any reason between 1997 and 1999.
