Purpose:
We assessed our institution's rate of perioperative and periprocedural corneal abrasions (CAs) and implemented a quality improvement project to improve our detection of CAs and decrease their incidence by at least 25% over 12 months.
Design:
Retrospective review before and after initiation of a quality improvement project at a single tertiary care institution METHODS: We retrospectively reviewed surgical and procedural patients requiring any type of anesthesia care over three 1-year time periods (2014-2015, 2016-2017, and 2017-2018). Using an electronic pharmacy-based query to identify patients who received proparacaine eye drops in the recovery room, we were able to estimate our incidence of CA during these time periods. We implemented a best practice plan to standardize CA prevention, diagnosis, and treatment after determining our baseline incidence of CA.
Findings:
Our baseline incidence rate of perioperative and periprocedural CAs was 0.22% (43/19,790 anesthetics) in the 2014-2015 time period. In the 2016-2017 and 2017-2018 time periods, the incidence rate was reduced to 0.09% (21/23,652 anesthetics) and 0.1% (23/23,825 anesthetics), respectively. The use of a standardized CA prevention, diagnosis, and treatment plan reduced the relative risk of CAs by 59% in 2016-2017 (P < .001) and 56% in 2017-2018 (P = .001) compared to baseline, with an absolute reduction of 13% and 12% over those time periods.
Conclusion:
Our data suggests that the adoption of a simple, standardized perioperative and periprocedural CA prevention, diagnosis, and treatment plan can result in sustained reductions in the occurrence of perioperative CAs.
