Variation in Condition-Specific Readmission Rates Across US Children's Hospitals.

Area of Science:

• Pediatric Healthcare Quality Improvement
• Hospital Readmission Analysis
• Health Services Research

Background:

• Pediatric hospital readmission rates have stagnated despite significant efforts.
• Understanding variation in readmission rates by condition is crucial for targeted interventions.

Purpose of the Study:

• To analyze readmission rates by condition across US children's hospitals.
• To identify priority conditions for future readmission reduction initiatives.

Main Methods:

• Retrospective cohort study of 811,434 index hospitalizations from 49 US children's hospitals (2017).
• Calculated 30-day unadjusted and risk-adjusted readmission rates using the Pediatric All Cause Readmission measure.
• Ranked conditions by rate variation (RV) across hospitals.

Main Results:

• Overall 30-day readmission rate was 6.2% (50,196 of 811,434 hospitalizations).
• Identified 33 conditions with high rate variation, accounting for 18% of discharges and 11% of readmissions.
• Common conditions like bronchiolitis, seizure, and asthma showed low rate variation.

Conclusions:

• Limited opportunities for improvement exist for common pediatric conditions with low readmission rate variation.
• Conditions with high rate variation offer quality improvement potential but have modest impact on national readmission rates.
