1. Clinical-radiological profile and risk factors for early mortality in preterm neonates with respiratory distress syndrome in Hoima, Western Uganda.
In a 7-day prospective cohort of 150 preterm neonates with clinically and radiologically confirmed RDS in Uganda, early mortality was 19.3%. Delayed presentation (>6 hours after birth) and birth weight <1.5 kg independently predicted death; tachypnea, retractions, and ground-glass radiographic patterns were common.
Impact: This study addresses an evidence gap in low-resource neonatal care by quantifying early mortality and identifying time-sensitive and weight-based predictors. Findings can guide triage and resource allocation in similar settings.
Clinical Implications: Prioritize rapid recognition and referral for preterm neonates with RDS, especially those <1.5 kg. Implement system-level interventions to reduce time-to-presentation and expand access to antenatal corticosteroids and basic respiratory supports (e.g., CPAP) to reduce early mortality.
Key Findings
- Seven-day early mortality among preterm neonates with RDS was 19.3% (29/150).
- Delayed presentation beyond 6 hours of life independently increased mortality risk (aRR 1.72, 95% CI 1.43–2.07, p<0.001).
- Birth weight <1.5 kg independently increased mortality risk (aRR 1.12, 95% CI 1.02–1.22, p=0.015).
- Tachypnea (84.7%) and intercostal/subcostal retractions (71.3%) were frequent, with ground-glass radiographic patterns predominating.
Methodological Strengths
- Prospective cohort design with radiographic confirmation of RDS.
- Multivariable Poisson regression reporting adjusted relative risks.
Limitations
- Single-center study with a modest sample size (N=150).
- Short 7-day follow-up limits assessment of later outcomes.
- Key interventions (antenatal corticosteroids, respiratory support) were not measured, raising residual confounding.
Future Directions: Multicenter implementation studies to reduce time-to-presentation and expand antenatal corticosteroids and CPAP; validation cohorts with longer follow-up and standardized radiographic severity scoring.
Respiratory distress syndrome (RDS) is the leading cause of respiratory failure and neonatal mortality, particularly in preterm infants. Despite global advances in neonatal care, RDS remains a significant problem in low-resource settings such as Uganda, where limited evidence exists on clinical profiles, mortality, and associated risk factors. Although these advances have greatly reduced mortality in high-income settings, their limited availability in Uganda contributes to the continued high burden of RDS-related deaths. To determine the clinical-radiological profile, early mortality, and risk factors for mortality among preterm neonates admitted with RDS at Hoima Regional Referral Hospital. A prospective cohort study was conducted among 150 preterm neonates with clinically and radiologically confirmed RDS. Data on sociodemographic, clinical, and obstetric characteristics were collected using structured questionnaires and chest X-rays. Participants were followed for seven days to determine outcomes. Descriptive statistics summarized baseline characteristics, while Poisson regression identified independent predictors of mortality. Of the 150 neonates, 62.7% were male and 70.7% were born before 32 weeks of gestation. Tachypnea (84.7%) and intercostal/subcostal retractions (71.3%) were the most frequent clinical features, while ground-glass patterns were the predominant radiological finding. Twenty-nine neonates died within the first seven days, giving an early mortality rate of 19.3%. Independent predictors of mortality were delayed presentation beyond six hours of life (aRR = 1.72, 95% CI: 1.43-2.07, p < 0.001) and birth weight < 1.5 kg (aRR = 1.12, 95% CI: 1.02-1.22, p = 0.015). RDS contributes substantially to early neonatal mortality in Uganda. Prompt recognition, early referral, and improved neonatal care-particularly for very low birth weight infants-are critical to improving outcomes. Although not directly measured in this study, improving access to antenatal corticosteroids and respiratory support-well-established interventions-remains essential for broader improvement of RDS outcomes.
2. Clinical-radiological profile and risk factors for early mortality in preterm neonates with respiratory distress syndrome in Hoima, Western Uganda.
Prospective data from 150 preterm infants with RDS show high early mortality and identify actionable predictors: delayed presentation and very low birth weight. Findings emphasize early triage and essential respiratory support in resource-limited neonatal units.
Impact: By quantifying risk in a low-resource African setting, the study provides context-specific evidence to optimize neonatal pathways and prioritize high-risk infants.
Clinical Implications: Adopt protocols to minimize time-to-presentation (e.g., in-facility deliveries, rapid postnatal assessment), and prioritize antenatal corticosteroids and CPAP availability for <1.5 kg infants.
Key Findings
- Early (7-day) mortality was 19.3% among RDS preterm neonates.
- Delayed presentation (>6 hours) was a strong independent predictor of death (aRR 1.72).
- Birth weight <1.5 kg independently increased mortality risk (aRR 1.12).
Methodological Strengths
- Clearly defined 7-day outcome window with prospective follow-up.
- Adjusted Poisson regression controlling for confounders.
Limitations
- Single-center design limits generalizability.
- Unmeasured care variables (e.g., antenatal steroids, respiratory support) may confound associations.
Future Directions: Prospective multicenter cohorts with standardized care metrics and pragmatic trials of antenatal steroids and CPAP in low-resource settings.

3. Clinical-radiological profile and risk factors for early mortality in preterm neonates with respiratory distress syndrome in Hoima, Western Uganda.
This study quantifies early mortality and identifies independent predictors in preterm RDS, providing actionable targets (reduce presentation delays, prioritize very low birth weight infants) for quality improvement in low-resource neonatal care.
Impact: Offers context-specific prognostic evidence for RDS in sub-Saharan Africa, a setting with high mortality and limited access to proven interventions.
Clinical Implications: Develop referral networks and standardized early assessment to ensure presentation within 6 hours; scale essential respiratory care and antenatal steroid programs to mitigate early deaths.
Key Findings
- Ground-glass radiographic patterns predominated in RDS cases; tachypnea and chest retractions were the most frequent clinical signs.
- Early mortality within 7 days was 19.3% (29/150).
- Independent mortality predictors: delayed presentation (>6 hours, aRR 1.72) and birth weight <1.5 kg (aRR 1.12).
Methodological Strengths
- Radiologic confirmation combined with structured clinical data collection.
- Appropriate statistical modeling (Poisson regression) for risk estimation.
Limitations
- Short follow-up window may underestimate later morbidity and mortality.
- Potential residual confounding due to unmeasured treatment variables.
Future Directions: Evaluate time-to-care interventions and scale-up of respiratory support using pragmatic designs; incorporate longer-term neurodevelopmental outcomes.
