To determine and analyze the geographic distribution of interventional radiologists in the United States to identify populations that have decreased accessibility to IR care.
The Society of Interventional Radiology public database was reviewed for board-certified interventional radiologists in all cities within the United States. US Census data was used to acquire county-level data sets on poverty, population, unemployment, median household income, education, and racial diversity. Odds ratios were calculated for access to IR care between the 75th and 25th percentile for each population variable. Counties with IRs were compared to counties without for each variable via t-Tests. QGIS was used to map the distribution of IRs.
2989 board-certified US interventional radiologists were found to be operating in 15.5% (n=487) of all counties. Almost a third of the country's population (31.2%) did not have access to an interventional radiologist within their county. The mean interventional radiologist:population ratio was 0.305 per 100,000 people. The average median income among counties with IRs was greater at $67,649 compared to $53,528 among counties without (P<0.05). In addition, an average of 31.3% of the population had a college degree in counties with IRs versus 20.3% in other counties (P<0.001). Higher average percentages of African Americans, Pacific Islanders, and Hispanics were observed in counties with IRs at 13.1%, 0.232%, and 13.7%, respectively (P<0.05).
Interventional radiologists are disproportionately distributed, with higher densities practicing near urban areas. Access is also limited to counties with higher incomes and a greater percentage of citizens with college education.
确定并分析美国介入放射科医生的地理分布，以找出获得介入放射治疗服务机会减少的人群。
查阅介入放射学会公共数据库，统计美国所有城市中获得委员会认证的介入放射科医生。使用美国人口普查数据获取县级层面有关贫困、人口、失业、家庭收入中位数、教育程度和种族多样性的数据集。计算每个人口变量第75百分位数和第25百分位数之间获得介入放射治疗服务的优势比。通过t检验比较有介入放射科医生的县和没有介入放射科医生的县在每个变量上的情况。使用QGIS绘制介入放射科医生的分布地图。
发现2989名获得委员会认证的美国介入放射科医生在所有县中的15.5%（n = 487）个县执业。该国近三分之一的人口（31.2%）在其所在县无法获得介入放射科医生的服务。介入放射科医生与人口的平均比例为每10万人0.305人。有介入放射科医生的县的平均收入中位数较高，为67,649美元，而没有介入放射科医生的县为53,528美元（P<0.05）。此外，有介入放射科医生的县平均有31.3%的人口拥有大学学位，而其他县为20.3%（P<0.001）。在有介入放射科医生的县中，非裔美国人、太平洋岛民和西班牙裔人的平均比例分别较高，为13.1%、0.232%和13.7%（P<0.05）。
介入放射科医生分布不均衡，在城市地区附近执业的密度较高。获得服务的机会也仅限于收入较高且大学教育程度公民比例较高的县。
