Predictors of antepartum maternal sepsis and effects on neonatal outcomes: a population-based cohort study.

OBJECTIVE

To examine the relationship between maternal sepsis, type of infection, and short-term neonatal outcomes.

STUDY DESIGN

We conducted a retrospective cohort study investigating pregnancies between 2005 and 2008 in California with antepartum maternal sepsis diagnosis. Comparisons were made between sepsis cases and controls, using chi-squared or Fisher's exact test. Multivariable logistic regression was performed, adjusting for maternal characteristics.

RESULTS

Several maternal characteristics were associated with increased odds of maternal sepsis. Both obstetric and non-obstetric infections were associated with maternal sepsis (p < 0.001). The positive predictive value of maternal sepsis for preterm delivery was 55.03%. Neonates born to maternal sepsis patients had a higher risk of developing neonatal complications including neonatal shock.

CONCLUSION

Maternal sepsis was associated with neonatal complications. Efforts to reduce maternal sepsis may improve neonatal outcomes. Further studies are required for a better understanding of these associations and whether prevention or more rapid diagnosis and treatment can lower these risks.
