Objective: To examine the impact of eye-care provider workforce on the receipt of yearly dilated eye examination among adults with diabetes.

Method: Data from the 2006 Behavioral Risk Factor Surveillance System were linked to 2007 Area Resource File to examine the association between number of eye-care providers (ophthalmologist and optometrist) per 100,000 population per county and use of preventive eye-care services (i.e., having dilated eye examinations in the past year). Our sample included adults aged 18 years or older with diabetes (N=29,495) in 2006. Multivariate logistic regressions were conducted to estimate adjusted odds ratios of yearly dilated eye examination controlling for age, gender, marital status, education, and health insurance.

Results: Approximately 25% of the respondents with diabetes lived in counties with less than one eye-care provider per 100,000 population. 69.4% of these counties were located in non-metropolitan areas. 94.5% of counties with 20+ eye-care providers per 100,000 population were within metropolitan areas. After controlling for covariates, people with diabetes in counties with less than one eye-care provider per 100,000 population (OR=0.76; 95%CI=0.62-0.94) and those with 1-9 eye-care providers per 100,000 population (OR=0.84; 95%CI=0.71-0.99) were less likely to report having a dilated eye examination in the past year compared with those with 20 or more eye-care providers per 100,000 population.

Conclusion: A fewer number of eye-care providers in a county of residence may influence the receipt of yearly dilated eye examination among adults with diabetes. Addressing the geographic distribution of eye-care providers could help improve vision health among people with diabetes.

Learning Objectives:
1. Describe the geographic distribution of eye care providers where people with diabetes live. 2.Describe the effect of eye-care provider workforce on the use of eye care services.
