Patient Demand for Ophthalmologists in the United States: A Google Trends Analysis.
Purpose: To study geographic patterns in ophthalmologist supply and patient demand for services in the United States.
Methods: Google Trends data for the keywords "ophthalmology" and "ophthalmologist" between 2004 and 2019 were queried and normalized to determine relative search volumes (RSV) for each United States state. Ophthalmologist density was calculated by dividing the number of practicing ophthalmologists by the State Census Bureau population estimates. RSV values were divided by ophthalmologist density and normalized to calculate the relative demand index (RDI) for each state. The number of accredited ophthalmology programs per state was acquired through the Accreditation Council for Graduate Medical Education.
Results: Ophthalmologist concentration was highly heterogeneous across the country. The states with the highest concentration of ophthalmologist per 10,000 people were Washington, DC (1.42), Maryland (0.94), Massachusetts (0.87), and New York (0.86), while the lowest were Wyoming (0.19), Idaho (0.36), New Mexico (0.38), and Nevada (0.39). RSVs ranged from 36 (Alaska and North Dakota) to 100 (Michigan). The highest RDI was found in South Dakota (100), Delaware (84), Michigan (66), and Arizona (56). The lowest RDI was in Washington, DC (0), Hawaii (7), Oregon (8), and Montana (14). The highest number of ophthalmology residency programs were in New York (18), Texas (9), and California (9), whereas 12 states lacked residency programs altogether.
Conclusions: In this study, we found a wide range in the geographic distribution of ophthalmologists and residency programs in the United States. States with the highest relative demand index may represent areas most at risk of unmet medical needs.
期刊介绍：
Ophthalmic Epidemiology is dedicated to the publication of original research into eye and vision health in the fields of epidemiology, public health and the prevention of blindness. Ophthalmic Epidemiology publishes editorials, original research reports, systematic reviews and meta-analysis articles, brief communications and letters to the editor on all subjects related to ophthalmic epidemiology. A broad range of topics is suitable, such as: evaluating the risk of ocular diseases, general and specific study designs, screening program implementation and evaluation, eye health care access, delivery and outcomes, therapeutic efficacy or effectiveness, disease prognosis and quality of life, cost-benefit analysis, biostatistical theory and risk factor analysis. We are looking to expand our engagement with reports of international interest, including those regarding problems affecting developing countries, although reports from all over the world potentially are suitable. Clinical case reports, small case series (not enough for a cohort analysis) articles and animal research reports are not appropriate for this journal.
