Hospitalization of children under five years of age due to avoidable causes

Area of Science:

• Pediatrics
• Public Health
• Epidemiology

Background:

• Childhood morbidity patterns are crucial for public health planning.
• Understanding hospital admission diagnoses in young children informs targeted interventions.
• Hospitalization data from Paraná, Brazil, provides insights into regional child health trends.

Purpose of the Study:

• To analyze the profile of hospital morbidity in children under five years old.
• To identify the primary diagnoses leading to hospitalization in this age group.
• To assess trends in pediatric hospital admissions over a 12-year period.

Main Methods:

• Retrospective analysis of hospital admission records from 1998 to 2009.
• Inclusion of 41,220 hospitalizations for individuals younger than five years old.
• Categorization of diagnoses based on the International Classification of Diseases (ICD).

Main Results:

• A significant decline of 16.1% in hospital admissions for children under five was observed relative to total admissions.
• Diseases of the respiratory system constituted the leading cause of hospitalization (55.6%).
• Infectious and parasitic diseases (14.8%) and perinatal conditions (12.9%) were the next most frequent diagnoses.

Conclusions:

• Pediatric hospital admissions show a downward trend, but specific diagnoses remain prevalent.
• Respiratory illnesses are a major burden, necessitating focused preventive strategies.
• Strengthening primary healthcare and child health programs is essential to further reduce preventable hospitalizations.
