Insights
Neonatal sepsis in Uganda is linked to lower developmental scores in 2-year-olds. Early intervention and monitoring are crucial for improving outcomes in high-risk infants.
Area of Science:
- Global child development
- Neonatal health outcomes
- Pediatric infectious diseases
Background:
- Neonatal sepsis is a major cause of infant mortality globally, especially in resource-limited areas.
- Long-term developmental impacts for survivors of neonatal sepsis are not well understood.
- This study investigates the developmental trajectory of children exposed to neonatal sepsis in Uganda.
Purpose of the Study:
- To assess the association between probable neonatal sepsis and developmental outcomes at 2 years of age.
- To evaluate the impact of neonatal sepsis on early childhood development in a Ugandan cohort.
- To inform strategies for follow-up and intervention for infants with neonatal sepsis.
Main Methods:
- Utilized the WHO Global Scales for Early Development (GSED) Short and Long Forms for assessment.
- Compared 100 infants with probable neonatal sepsis against 304 age-matched controls.
- Employed linear regression and inverse probability of treatment weighting, adjusting for confounders.
Main Results:
- Children with probable neonatal sepsis showed significantly lower GSED Z-scores for both parent-reported (Short Form) and directly observed (Long Form) development.
- Adjusted mean difference in GSED Short Form Z-scores was -0.22 (95% CI -0.47 to -0.04).
- Adjusted mean difference in GSED Long Form Z-scores was -0.33 (95% CI -0.60 to -0.05).
Conclusions:
- Neonatal sepsis is associated with poorer developmental outcomes in resource-limited settings.
- Effective follow-up, monitoring, and early intervention strategies are essential for infants with probable neonatal sepsis.
- Further research is needed to optimize care for sepsis survivors in low-resource environments.
Background:
Neonatal sepsis is a common cause of mortality and morbidity during the first 28 days of life, particularly in resource-limited settings. Of those infants who survive sepsis, there is a lack of clarity as to the likelihood of developmental difficulties in these children. This study aimed to understand the impact of probable neonatal sepsis on the development of 2-year-old children in Uganda.
Methods:
We assessed 404 infants aged between 18 and 36 months using the WHO's Global Scales for Early Development (GSED) Long Form (directly observed) and Short Form (parent report). This included 100 infants treated for probable neonatal sepsis and were part of a large community infection prevention trial (BabyGel). We then recruited 304 age-matched children from the same communities who took part in the parent trial but had no probable neonatal sepsis. We used linear regression and inverse probability of treatment weighting analyses to calculate measures of association and effect. We adjusted for the clustering effect, trial arm or other confounders.
Results:
The mean age (SD) of children in our cohort was 23.3 months (4.4) in both groups. GSED development for age Z-scores were significantly lower for the children with a probable sepsis diagnosis compared with those without for both the GSED Short Form -0.22, 95% CI -0.47 to -0.04 and the GSED Long Form -0.33, 95% CI -0.60 to -0.05 when adjusted. An additional model adjusting for HIV exposure as a confounder (only available 373/404) provided similar results with adjusted mean GSED Short Form developmental age Z-scores difference of -0.29, 95% CI -0.53 to -0.04 and -0.33, 95% CI -0.59 to -0.07 for GSED Long Form.
Conclusion:
Neonatal sepsis may be associated with poorer developmental outcomes in resource-limited settings such as Uganda. To ensure better outcomes for these children, it is vital to explore more effective strategies for follow-up, monitoring and early interventions in infants with probable neonatal sepsis.
