Abstract
BACKGROUND AND OBJECTIVE: To report the effect of a "no-talking" policy during intravitreal injection (IVI) on post-injection endophthalmitis.
PATIENTS AND METHODS: Retrospective, comparative, consecutive case series of patients receiving IVI between Jan. 1, 2009, and Dec. 31, 2012. A 24-month "usual care" period was compared to a 24-month no-talking period, during which a strategy to further minimize speech during IVI was implemented.
RESULTS: During the usual care period, 47,155 IVIs were performed, with nine culture-positive cases (0.019%), including seven due to oral pathogens (0.015%). During the no-talking period, 82,658 IVIs were performed, with eight culture-positive cases (0.010%), including two due to oral pathogens (0.002%). The no-talking policy was associated with a decreased endophthalmitis risk (P = .004), including oral pathogen-associated endophthalmitis (P = .02).
CONCLUSION: This study demonstrates that a more stringent no-talking policy during IVI may reduce the risk of post-injection endophthalmitis.
