Purpose:
We aim to describe ocular infection epidemiology for a public tertiary care hospital in New York City (NYC).
Methods:
We retrospectively reviewed 558 patients with ocular isolates from conjunctival, corneal, and intraocular culture from 2009 to 2017 for microbial growth and antimicrobial sensitivities.
Results:
In total, 185 ocular cultures (33%) had growth and the most commonly isolated microbes overall were Staphylococcus aureus (S. aureus) (23%), coagulase-negative Staphylococcus (CoNS) (23%), Pseudomonas aeruginosa (P. aeruginosa) (16%), and Streptococcus viridans (S. viridans) group (11%). The most common microbes within corneal (n = 61), conjunctival (n = 34), and intraocular isolates (n = 9) were P. aeruginosa (37.7%), S. aureus (35.3%), and S. viridans group (33.3%), respectively. Proportion of isolates exhibiting multi-drug resistance decreased over time (P = .006).
Conclusions:
The microbial epidemiology of ocular infection of a public NYC hospital was distinct from other geographic locations, underscoring the importance of examining local profiles to more precisely inform empiric therapy.

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.

The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
