Outcome of very low birthweight infants who required prolonged hospitalization
Insights
Very low birthweight infants needing prolonged hospitalization face higher post-discharge mortality and developmental issues. Comprehensive support is crucial for these vulnerable infants after hospital discharge.
Area of Science:
- Neonatology
- Pediatric Health
- Perinatal Medicine
Background:
- Very low birthweight infants (VLBWIs) often require extended initial hospitalization.
- The long-term outcomes for these infants, particularly those with prolonged stays, require further investigation.
Purpose of the Study:
- To evaluate the post-discharge outcomes of VLBWIs based on the duration of their initial hospitalization.
- To identify specific morbidities and developmental challenges associated with prolonged initial hospital stays in VLBWIs.
Main Methods:
- A 4-year study followed 294 surviving VLBWIs (birthweight ≤ 1500 g).
- Infants were categorized based on discharge gestational age, with a focus on those discharged after 40 weeks (prolonged hospitalization).
- Outcomes assessed included post-discharge mortality, significant infections, rehospitalization, growth parameters, major disability, and developmental delay at 2 years.
Main Results:
- Infants with prolonged initial hospitalization (discharged ≥ 40 weeks) had significantly higher post-discharge mortality (6% vs 1%).
- These infants experienced higher rates of significant infections (66%) and rehospitalization (54%) within the first 2 years.
- Major disability (27% vs 15%) and developmental delay (13% vs 4%) were significantly more prevalent in the prolonged hospitalization group.
Conclusions:
- Prolonged initial hospitalization in VLBWIs is associated with increased post-discharge mortality and significant morbidities.
- These infants exhibit higher rates of major disability and developmental delay by 2 years of age.
- Comprehensive medical and social support is essential for VLBWIs during and after prolonged initial hospitalization.
Abstract:
Over a 4 year study period, 294 infants with a birthweight less than or equal to 1500 g survived their initial hospitalization; 103 (35%) were discharged after a gestational age of 40 weeks. The postdischarge infant mortality was significantly higher in those with prolonged initial hospitalization compared with the remaining survivors (6% vs 1%). During the first 2 years, significant infections were found in 66% and rehospitalization in 54% of the children who had prolonged initial hospitalization. At 2 years, 34% were below the 10th centile for weight as were 39% for height; head circumferences were normal. Major disability (27% vs 15%) and developmental delay (13% vs 4%) were significantly more common in survivors with prolonged initial hospitalization compared with the remaining survivors. The study demonstrated the continuing toll of perinatal morbidity among very low birthweight infants who required prolonged hospitalization and emphasized the need for comprehensive medical and social support, not only during their initial hospitalization, but also after discharge.
