Reducing preterm mortality in eastern Uganda: the impact of introducing low-cost bubble CPAP on neonates <1500 g
Insights
Low-cost bubble continuous positive airway pressure (bCPAP) significantly reduced mortality in very-low-birth-weight neonates with respiratory distress syndrome in Uganda. This affordable intervention shows promise for improving survival rates in low-income countries.
Area of Science:
- Neonatal Medicine
- Public Health
- Medical Devices
Background:
- Complications of prematurity, particularly respiratory distress syndrome (RDS), are a leading cause of under-five mortality.
- Limited treatment options for RDS exist in low-income countries (LICs).
- Low-cost bubble continuous positive airway pressure (bCPAP) devices offer a simple, affordable solution for RDS in neonatal units.
Purpose of the Study:
- To evaluate the impact of introducing bCPAP on the outcomes of very-low-birth-weight (VLBW) neonates in a LIC.
- To compare mortality rates in VLBW neonates before and after the implementation of bCPAP therapy.
- To assess the effectiveness of an affordable intervention in a resource-limited setting.
Main Methods:
- Retrospective study of VLBW neonates (<1500g) at Mbale Regional Referral Hospital Neonatal Unit in Uganda.
- Comparison of outcomes between a pre-bCPAP period (14 months) and a post-bCPAP period (18 months).
- bCPAP was applied to preterm neonates with RDS when clinically indicated and devices were available.
Main Results:
- Mortality rate decreased from 39.2% in the pre-bCPAP period to 26.5% in the post-bCPAP period (P=0.012).
- Overall mortality reduction of 44% was observed (OR 0.56, 95% CI 0.36-0.86, P=0.01).
- No significant differences were found in birthweight, sex, or presence of respiratory distress/apnea between the groups.
Conclusions:
- Resource-appropriate neonatal care, like bCPAP, can significantly reduce neonatal deaths in LICs.
- The introduction of low-cost bCPAP led to a significant improvement in VLBW neonate survival.
- This affordable intervention holds potential for substantial impact on global neonatal mortality rates.
Background:
Complications of prematurity are the leading cause of deaths in children under the age of five. The predominant reason for these preterm deaths is respiratory distress syndrome (RDS). In low-income countries (LICs) there are limited treatment options for RDS. Due to their simplicity and affordability, low-cost bubble continuous positive airway pressure (bCPAP) devices have been introduced in neonatal units in LICs to treat RDS. This study is the first observational study from a LIC to compare outcomes of very-low-birth-weight (VLBW) neonates in pre- and post-CPAP periods.
Methods:
This was a retrospective study of VLBW neonates (weight < 1500 g) in Mbale Regional Referral Hospital Neonatal Unit (MRRH-NNU), a government hospital in eastern Uganda. It aimed to measure the outcome of VLBW neonates in two distinct study periods: A 14-month period beginning at the opening of MRRH-NNU and covering the period until bCPAP was introduced (pre-bCPAP) and an 18-month period following the introduction of bCPAP (post-bCPAP). After the introduction of bCPAP, it was applied to preterm neonates with RDS when clinically indicated and if a device was available. Clinical features and outcomes of all neonates < 1500 g were compared before and after the introduction of bCPAP.
Results:
The admission records of 377 VLBW neonates < 1500 g were obtained. One hundred fifty-eight were admitted in the pre-bCPAP period and 219 in the post-bCPAP period. The mortality rate in the pre- bCPAP period was 39.2% (62/158) compared with 26.5% (58/219, P = 0.012) in the post-bCPAP period. Overall, there was a 44% reduction in mortality (OR 0.56, 95%CI 0.36-0.86, P = 0.01). There were no differences in birthweight, sex, presence of signs of respiratory distress or apnoea between the two groups.
Conclusion:
Specialized and resource-appropriate neonatal care, that appropriately addresses the challenges of healthcare provision in LICs, has the potential to reduce neonatal deaths. The use of a low-cost bCPAP to treat RDS in VLBW neonates resulted in a significant improvement in their survival in a neonatal unit in eastern Uganda. Since RDS is one of the leading causes of neonatal mortality, it is possible that this relatively simple and affordable intervention could have a huge impact on global neonatal mortality.
