Clinical Scorecard: Outcomes of Very Preterm Infants (<32 Weeks’ Gestation) Surviving Without Major Morbidity: A Single-Center Retrospective Study on Prevalence, Trends, and Contributing Factors

At a Glance

CategoryDetail
ConditionVery Preterm Infants (VPIs)
Key MechanismsSurvival without major morbidity (SWMM) is influenced by gestational age, birth weight, sex, surfactant doses, and Apgar scores.
Target PopulationInfants born at <32 weeks’ gestation admitted to NICU.
Care SettingNeonatal Intensive Care Unit (NICU)

Key Highlights

  • Among 1,094 VPIs receiving complete care, 95.5% survived, but only 59.9% achieved SWMM.
  • SWMM rates showed a decreasing trend over time despite stable survival rates.
  • Each additional week of gestational age significantly increased the odds of SWMM.
  • Male sex and lower Apgar scores were associated with decreased odds of SWMM.
  • DAMA occurred in 6.7% of VPIs, with decreasing frequency as gestational age increased.

Guideline-Based Recommendations

Diagnosis

  • SWMM defined as survival without bronchopulmonary dysplasia (BPD), severe brain injury, necrotizing enterocolitis (NEC) stage II or higher, late-onset sepsis (LOS), or severe retinopathy of prematurity (ROP).

Management

  • Implement GA-stratified care and optimized perinatal stabilization.

Monitoring & Follow-up

  • Track temporal trends in SWMM and associated factors to inform quality improvement.

Risks

  • Increased risk of BPD and severe ROP over time among surviving VPIs.

Patient & Prescribing Data

Very preterm infants (<32 weeks’ gestation) admitted to NICU.

Surfactant therapy and careful monitoring of Apgar scores are critical in managing VPIs.

Clinical Best Practices

  • Enhance early respiratory management for VPIs.
  • Reduce the incidence of DAMA through improved parental counseling.
