Background: Respiratory Distress Syndrome (RDS) is the leading cause of mortality of preterm infants in low- and middle-income countries (LMIC). Lack of diagnostic tools, such as radiography, blood gas analysis, and continuous pulse oximetry along with a scarcity of human resources highlight the need for objective clinical assessments of RDS that can be implemented by multi-disciplinary newborn care providers.
Objective: To assess the correlation of modified Downes’ scores (MDS) assigned by physicians and nurses on admission assessments of preterm infants with RDS in the Ethiopian Neonatal Network (ENN)
Design/Methods: We included infants with gestational age < 37 weeks with respiratory distress present on admission and treated with oxygen, continuous positive airway pressure (CPAP) or mechanical ventilation within 24 hours and admitted to four tertiary neonatal intensive care units (NICUs) participating in the ENN from June 2019 to June 2020. Nurses and physicians received training on the MDS (Figure), and national guideline for CPAP initiation prompting treatment for scores of 4 or greater combined with an oxygen requirement. The MDS was incorporated into admission assessments, and when feasible, concurrent and independent assessments were completed and recorded by a nurse and physician. We calculated the kappa statistic to determine the nurse and physician correlation for each component of the MDS and the total score, and evaluated the concordance of scores above and below the treatment threshold of 4.
Results: Of the 1016 eligible infants admitted, 1005 (99%) had MDS recorded on admission; 818 infants (81%) had scores reported by nurses; 997 infants (98%) had scores reported by physicians; 817 infants (80%) had scores reported concurrently by both nurses and physicians. The kappa statistic for MDS components ranged from 0.88 to 0.92 and was 0.89 for the total score (Table 1). Of the 817 infants concurrently assessed and scored, 98% had concordance above or below the score-based treatment threshold of 4 (Table 2).Conclusion(s): Incorporation of an objective clinical assessment on admission for preterm infants with RDS was feasible in tertiary NICU settings of the ENN. The kappa statistics of the components of the MDS and total score showed near-perfect agreement between nurse and physician assessments, translating to a very high degree of concordance in score-based treatment recommendations. As LMIC NICUs prioritize improving RDS care and quality of care, these findings reinforce nursing empowerment and task shifting standardized assessments and initiation of CPAP within the context of a multi-disciplinary team.
