Perinatal morbidity scores help researchers assess adverse maternal-infant events. A new Poisson regression method allows formal evaluation of these scores, improving their use in health research.

Area of Science:

  • Maternal-infant health research
  • Biostatistics
  • Health services research

Background:

  • Perinatal morbidity scores capture diverse adverse events in maternal-infant health.
  • These scores are valuable for researchers but challenging to implement as primary outcomes due to statistical difficulties.
  • Existing methods struggle to formally compare morbidity scores between study groups.

Purpose of the Study:

  • To address the challenges in statistically evaluating perinatal morbidity scores.
  • To introduce a novel Poisson regression-based approach for formal comparison of these scores.
  • To demonstrate the application of this method using the Adverse Outcome Index in a real-world scenario.

Main Methods:

  • Development of a statistical solution using Poisson regression for evaluating perinatal morbidity scores.

  • Application of the Poisson regression model to an existing scoring tool, the Adverse Outcome Index.
  • Case study analysis of labor and delivery safety before and after obstetrical service closures in rural communities.

    • Main Results:

    • The proposed Poisson regression method allows for formal statistical evaluation of differences in perinatal morbidity scores.
    • Analysis using the Adverse Outcome Index revealed a protective risk ratio for adverse outcomes post-closure of rural obstetrical services.
    • This contrasts with the original analysis, which found no significant difference.

    Conclusions:

    • The Poisson regression approach facilitates broader implementation of perinatal morbidity scores as primary outcomes in research.
    • This method enhances the ability to formally assess the impact of interventions or changes in healthcare services on maternal-infant outcomes.
    • The study supports the use of robust statistical methods for analyzing complex perinatal health data.
