From October 2011 to June 2015, the Canadian Association of Optometrists (CAO) collected 2,983 Optometry Incident Report (OIR) forms from participating English and French speaking members. From October 2011 until May 2014, members responded online to the original series of incident-related questions. From May until December 2014, the CAO conducted a campaign to improve the efficacy of the OIR. This campaign entailed two parts: a) Revising questions based on member feedback; and b) Updating the link to the OIR on the CAO website. Upon review by advising Optometrists, the OIR questions received a second series of updates in February 2015. Since April 2014, data collected in the OIR has been used to support policy development regarding eye care, specifically to emphasize the impact of early diagnosis on long-term healthcare costs. The following report provides an overview of the data disclosed in the Optometry Incident Report (OIR) between December 2011 and June 2015.
