This research provides a nationwide overview of vision care provided by optometrists identifying gaps in geographic availability relative to вЂњsupplyвЂќ and вЂњneedвЂќ factors. older age, low income) are located throughout Canada and identified with maps indicating areas of likely greater need for optometry services. HRs with a low optometrist ratio relative to eye care utilization and a high proportion of key sociodemographic characteristics (e.g. Thirty-five HRs were classified as low utilization, 39 HRs were classified as moderate, and 32 HRs as high utilization. Out of 109 health regions (HRs), 26 were classified as low ratios, 51 HRs were classified as moderate ratios, and 32 HRs were high ratios. The national mean ratio of optometrists was 1.70 optometrists per 10,000 people (rangeвЂ‰=вЂ‰0.13 to 2.92). The nationwide distribution of optometrists is variable across Canada they are predominantly concentrated in urban areas. ResultsДЄ total of 5959 optometrists across ten Canadian provinces were included in this analysis.

Three classes: low (вЂ‰0.5SD) were used for demonstrating distribution of each variable across health regions. Each variable was converted into three classes (i.e., low, moderate, and high) using a standard deviation (SD) classification scheme where вђ.5SD from the mean was considered as a cut-off. Cross-classification mapping compared optometrist distribution to self-reported use of vision care services in relation to need. Data from the 2016 Statistics Canada census were used to create three population вЂneedвЂ™ subgroups (65вЂ‰years and over low-income and people aged 15 and over with less than a high school diploma). Utilization of vision care services was extracted from the Canadian Community Health Survey (CCHS) 2013вЂ“2014 question regarding self-reported contacts with optometrists or ophthalmologists. the number of providers per 10,000 people at the health region level) were then calculated. Optometrist locations were gathered from provincial regulatory bodies. This research investigates the distribution of optometrists in Canada relative to population health needs and self-reported use of vision services.
