- Abstract
Background: Neonatal sepsis is a leading cause of death in low- and middle- income countries (LMIC). Increasing antibiotic resistance in early onset (< 72 h of life) bloodstream infection (EO-BSI) pathogens in LMIC has reduced the effectiveness of the recommended empiric antibiotic regimen (ampicillin plus gentamicin)., Methods: We retrospectively analysed blood culture-confirmed EO-BSI episodes at nine neonatal units from three central and six peripheral hospitals in the Western Cape Province, South Africa between 1 January 2017 and 31 December 2018. Clinical and electronic laboratory records were reviewed to determine pathogen profile, empiric antibiotic coverage rates and factors associated with EO-BSI attributable mortality, stratified by hospital type., Results: Of the 8252 blood culture specimens submitted for the investigation of suspected EO-BSI, 136 EO-BSI episodes yielding 141 pathogens were identified with an EO-BSI rate of 1.3 and 0.5 episodes/1000 live births at central and peripheral hospitals respectively. Preterm (93/136; 68.3%) and low birth weight (84/136; 61.8%) neonates were most affected. The predominant pathogens were Streptococcus agalactiae (46/136; 34%), Klebsiella pneumoniae (17/136; 13%), Listeria monocytogenes (11/136; 8%), Acinetobacter baumannii (11/136; 8%) and Escherichia coli (11/136; 8%). The empiric antibiotic (ampicillin plus gentamicin) coverage rate was 64% (95% CI 51-74) at central hospitals and 84% (95% CI 74-94) at peripheral hospitals. Neonates with Gram-negative EO-BSI and discordant empiric antibiotic therapy had almost four-fold and three-fold higher odds of death respectively., Conclusion: Preterm and low birth weight neonates are most vulnerable to EO-BSI and have higher odds of death with Gram-negative pathogens and discordant empiric antibiotic therapy., Competing Interests: Declarations.
