Diabetes Prevention Program Sites Compared With Diabetes Prevalence and Ratio of Primary Care Physicians in Texas
GIS SNAPSHOT — Volume 16 — December 26, 2019
PEER REVIEWED
The figure consists of 2 maps: one shows the age-adjusted prevalence of diagnosed diabetes by county (2014–2016) and the other shows the ratio of primary care physicians per 100,000 population by county (September 2018). Both maps show the locations of Diabetes Prevention Programs (DPPs) in the state as of 2019. There is a concentration of DPP sites throughout East Texas.
The first map shows the prevalence of diagnosed diabetes is higher in East Texas than in the rest of the state. Other areas with high prevalence are clusters of counties in North Texas and counties along the US-Mexico border. Many of the counties with the highest rates of diagnosed diabetes do not have DPP sites at all, nor are there sites in nearby counties. The second map shows that many counties in East Texas have low ratios of primary care physicians per 100,000 population.
Data sources: Diabetes Prevention Program (DPP) locations retrieved from National Center for Chronic Disease Prevention and Health Promotion, Division of Diabetes Translation, May 3, 2019. Percentage of diagnosed diabetes cases among persons aged 20 years or older, by Texas county (2015) downloaded from the Interactive Atlas of Heart Disease and Stroke, a website developed by the Centers for Disease Control and Prevention, Division for Heart Disease and Stroke Prevention, May 2019, https:// nccd dot cdc dot gov/DHDSPAtlas. State average of diagnosed diabetes cases was 11.2% in 2015. DPP sites represented are in-person sites only; no virtual DPP sites are included. There were 49 DPPs as of May 2019; Health Professions Resource Center, Center for Health Statistics, Texas Department of State Health Services, https:// www dot dshs dot Texas dot gov/chs/hprc/tables/2018/PC18 dot aspx. Primary care physician data represent the ratio of primary care physicians per 100,000 population in their county of practice, as of September 2018. Data on primary care physicians excludes physicians classified as federal (military, Veterans Administration, Public Health Service), and residents and fellows. This exclusion represents an estimated 9% to 10% of the direct patient care physician workforce.
These maps show the prevalence of diabetes and the ratio of primary care physicians in each county in Texas. Additionally, the maps display the locations of the 49 Diabetes Prevention Program (DPP) sites throughout Texas, as of May 3, 2019. These maps can be used by the Texas Department of State Health Services, health care organizations, or health care providers to identify priority locations for new DPP sites.
