Abstract:
Our study investigates the causative pathogens of hospital-acquired conjunctivitis in our neonatal intensive care unit and their susceptibility patterns. Coagulase-negative Staphylococcus was the most common bacterium, 22.1% of all isolates. The frequency of the pathogens changed during neonates' stay; Klebsiella pneumoniae (from 18% to 6.9%) and Escherichia coli (from 16% to 4.8%) decreased, whereas methicillin-susceptible Staphylococcus aureus (from 4% to 12.7%) and Enterococcus spp (from 1% to 5.3%) increased. Gram-positive cocci showed high resistant patterns. Our study indicates that the distribution of bacteria causing hospital-acquired conjunctivitis in our neonates shifted from gram-negative to gram-positive microorganisms during their neonatal intensive care unit stay. The resistance patterns are worrisome among gram-positive cocci.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
