Clinical Presentation, Investigation and Control of an Outbreak of Adenoviral Conjunctivitis in a Neonatal Unit at a Tertiary Hospital

Neonatal Healthcare-Associated Conjunctivitis: A Descriptive Study from Saudi Arabia

Healthcare-associated conjunctivitis (HAC) has been associated with serious ophthalmological complications in neonates, including blindness. This three-year retrospective, descriptive study was conducted between 2019 and 2021 to determine the most common bacteria associated with neonatal HAC at a tertiary-care hospital in Saudi Arabia. The inclusion criteria were defined based on the centers for disease control and prevention (CDC) guidelines for the diagnosis of neonatal HAC. When HAC was clinically suspected, conjunctival swabs were obtained from neonates and sent to the microbiology lab following standard protocols. A univariate analysis was conducted on the included samples. A total of 79 cases met our inclusion criteria and were retrospectively studied. A descriptive analysis showed that Pseudomonas aeruginosa was the leading cause of HAC, with 25% (20 cases), followed by Escherichia coli and Klebsiella pneumonia (11.5% for each). About 9% of the analyzed cases were positive for Staphylococcus aureus. Orogastric feeding was the most commonly (94%) associated factor with HAC, followed by respiratory distress syndrome (RDS) and preterm birth, which were found in 70% and 64% of the cases, respectively. To conclude, HAC is an alarming healthcare problem, and bacteria, including Gram-negative bacteria, are common causes. Thus, physician awareness, effective communication with microbiologists, and the implementation of infection control recommendations, including hand hygiene, could minimize this problem and avoid the serious complications of HAC.
