1. Epidemiology of Neonatal Brachial Plexus Palsy in the United States: Years 1997, 2000, 2003 CT Mehlman, DO, MPH,
SL Foad, MPH, J Ying, PhD
Cincinnati, Ohio
USA
2. PURPOSE
3. METHODS The nationwide Kids Inpatient Database (KID) was utilized
KID was developed as part of the Health Care Utilization Project (HCUP)
The KID is a sample of pediatric (birth -20 years old) discharges from all community, non-rehabilitation hospitals in participating states
ICD-9 codes were utilized to identify neonates with NBPP and risk factors for NBPP
4. METHODS Univariate Analysis
Multivariate Logistic Regression
SAS-callable SUDDAN version 9.0.1 (Research Triangle Institute)
5. RESULTSIncidence of NBPP in USA
6. RESULTS
Rate of instrumented delivery, breech delivery, shoulder dystocia, and exceptionally large baby (> 4.5 kg) ?1997 to 2003 (p<0.01)
Rate of cesarean delivery, heavy for date, and twin/multi born ? 1997 to 2003 (p<0.01)
7. RESULTS Adjusted Odds Ratio
8. CONCLUSIONS
US incidence of NBPP
1.5 per 1000 live births
Significant ? 1997 to 2003
9. CONCLUSIONS
Risk Factors that confer HIGHER RISK
Shoulder Dystocia = chances of NBPP are 100 X higher
Exceptionally Large Baby (>4.5 kg) = chances of NBPP are 14 X higher
Instrumented Delivery = chances of NBPP are 8 X higher
10. CONCLUSIONS
Risk Factors that confer LOWER RISK
C-section = chances of NBPP are 8 X lower
Twin / Multi Born = chances of NBPP are 4 X lower
