Long-term follow-up of Victorian infants shows improved survival and quality of survival for extremely preterm and low-birthweight infants. Regionalized care enhanced efficiency, demonstrating the value of population-based studies for perinatal program evaluation.

Area of Science:

  • Neonatal care
  • Perinatal epidemiology
  • Longitudinal cohort studies

Background:

  • Evaluating regionalized perinatal-neonatal care requires robust population-based follow-up.
  • Previous studies often relied on institution-based data, limiting comprehensive outcome assessment.

Purpose of the Study:

  • To assess the effectiveness and efficiency of a regionalized perinatal-neonatal care program.
  • To evaluate survival and quality-adjusted survival rates in extremely-low-birthweight and extremely-preterm infants over time.

Main Methods:

  • Population-based, geographically determined cohort study in Victoria.
  • Follow-up of consecutively born infants (<1000g or <28 weeks' gestation) up to 14 years of age.
  • Analysis across four distinct time periods (1979-1997) to track trends.

Main Results:

  • Significant improvements in both survival and quality-adjusted survival rates were observed across all subgroups.
  • Increasing proportion of high-risk infants born in level III perinatal centers correlated with improved outcomes.
  • Cost-effectiveness and cost-utility ratios remained stable, with efficiency gains noted in smaller infants.

Conclusions:

  • Regionalized, population-based long-term follow-up studies provide critical data for optimizing perinatal-neonatal care programs.
  • The study demonstrates the success of regionalized care in improving outcomes for high-risk infants.
  • This approach offers unique insights unobtainable from institution-based studies.
