Complexity and Severity of Pediatric Patients Treated at United States Emergency Departments

Area of Science:

• Pediatric Emergency Medicine
• Health Services Research
• Public Health

Background:

• Emergency departments (EDs) serve diverse patient populations, including children.
• Understanding differences in patient complexity and outcomes between general and pediatric EDs is crucial for optimizing care.
• Existing data may not fully capture the nuances of pediatric patient presentations in different ED settings.

Purpose of the Study:

• To compare the complexity and severity of pediatric patients presenting to general versus dedicated pediatric emergency departments (EDs).
• To analyze differences in critical procedures and hospitalization rates between these two ED types.
• To inform educational strategies for healthcare professionals managing children with complex health needs.

Main Methods:

• Cross-sectional study utilizing the National Emergency Department Sample (NEDS) from 2008 to 2012.
• EDs classified as 'pediatric' (>75% of patients <18 years) or 'general'.
• Patient complexity assessed via International Classification of Diseases, Ninth Revision (ICD-9) codes for chronic conditions; severity evaluated using a standardized classification system.

Main Results:

• Identified 9.6 million pediatric ED encounters and 169 million general ED encounters.
• Pediatric EDs saw a higher proportion of younger children (<1 year) and medically complex cases (5% vs. 2%).
• Hospitalization rates were significantly higher in pediatric EDs (10% vs. 4%), despite similar severity classification scores.

Conclusions:

• Pediatric EDs manage a greater proportion of medically complex children compared to general EDs.
• Higher hospitalization rates in pediatric EDs reflect the acuity and complexity of the patient population served.
• Findings underscore the importance of specialized training to ensure high-quality care for children with complex health care needs in emergency settings.
