‘No-talking’ policy may reduce endophthalmitis risk after intravitreal injection
A strict “no-talking” policy during intravitreal injections reduced the risk of endophthalmitis after the injections, according to a study.
“Some studies found that wearing face masks reduces endophthalmitis risk, whereas others suggest that adopting silence or a no-speaking policy may reduce speech-related contamination of the surgical field. However, no study has demonstrated that an intervention designed to reduce transmission of oral flora results in a decreased risk of endophthalmitis,” the study authors said.
The retrospective study conducted at Wills Eye Hospital included 47,155 intravitreal injections performed during a 24-month usual care period and 82,658 injections performed during a 24-month no-talking period.
The average interval between injection and presentation with endophthalmitis was 3.6 days for the usual care and no-talking periods.
During the usual care period, nine culture-positive cases were reported (0.019%), of which seven resulted from oral pathogens (0.015%). During the no-talking period, eight culture-positive cases were reported (0.010%), of which two resulted from oral pathogens (0.002%).
The silence policy was associated with a significant reduction in the risk of endophthalmitis (P = .004) and oral pathogen-associated endophthalmitis (P = .02). – by Matt Hasson
