Severe bacterial and fungal infections (sepsis) are a leading cause of mortality among neonates in sub-Saharan Africa. In African neonatal units, most sepsis episodes are hospital acquired, and caused by Gram-negative, antimicrobial-resistant pathogens. With rising rates of antimicrobial resistance (AMR) in neonatal sepsis pathogens, there is an increasing probability of inappropriate empirical antibiotic therapy (so called ‘bug-drug’ mismatch or discordant therapy), as confirmation of pathogen identity and antibiotic susceptibility pattern is either not available or delayed. The impact of AMR and discordant empirical treatment on neonatal sepsis outcomes in Africa is largely unknown owing to the lack of the infection surveillance data needed to derive empirical antibiotic treatment recommendations. The Antibiotics for Neonatal Sepsis in Africa (ANSA) study will address this data gap by pooling and harmonising available single-centre research datasets and/or routine laboratory blood culture data to determine which antibiotics should be used for empirical treatment of neonatal sepsis. However, many challenges hamper these datasets, including: variable laboratory methods for pathogen identification and susceptibility testing; difficulty in collating and harmonising data from multiple sites; problems of record linkage in the absence of a single patient identifier; lack of centralised health data capturing systems; and difficulty accessing data due to complex data sharing agreements and custodian permissions. To overcome some of these challenges, minimum guidelines for the collection of neonatal sepsis data need to be defined, to ensure consistency between datasets. Greater collection of, access to and sharing of neonatal sepsis data from institutional, provincial and national laboratories, as well as individual neonatal units, would enable the establishment of a neonatal surveillance network. Development of a sustainably-funded neonatal sepsis surveillance network is a national priority, to ensure effective, evidence-based antimicrobial treatment of hospitalised neonates in South Africa.
