背景虽然获得癌症护理已知会影响患者的预后，但据作者所知，关于获得癌症护理的地理位置以及如何因人口特征而异，我们知之甚少。这项研究估计了美国大陆人口前往专门癌症护理机构的旅行时间，并计算了人均肿瘤学家供应。最近的旅行时间是使用从美国大陆每个ZIP地区的人口或地理质心到最近的癌症护理环境的旅行速度加权的道路距离的网络分析来估计的：国家癌症研究所（NCI）指定的癌症中心，学术医疗中心和肿瘤学家。阿拉斯加和夏威夷被排除在外，因为在这些州旅行往往不是基于公路的。人口和地理特征，包括种族/民族，收入，教育和地区来自美国2000年人口普查数据和城乡通勤地区分类。按地区估计医院转诊区域（pHRR）中每100，000名居民的肿瘤医生供应量。走时
BACKGROUND. Although access to cancer care is known to influence patient outcomes, to the authors' knowledge, little is known regarding geographic access to cancer care, and how it may vary by population characteristics. This study estimated travel time to specialized cancer care settings for the continental U.S. population and calculated per capita oncologist supply.METHODS. The closest travel times were estimated using a network analysis of the road distance weighted by travel speeds from the population or geographic centroid of every ZIP area in the continental U.S. to that of the nearest cancer care setting under consideration: National Cancer Institute (NCI) -designated Cancer Centers, academic medical centers, and oncologists. Alaska and Hawaii were excluded because travel in these states is often not road-based. Population and geographic characteristics including race/ethnicity, income, education, and region were derived from U.S. Census 2000 data and from rural-urban commuting area classifications. Oncologist supply per 100,000 residents in Hospital Referral Regions (pHRRs) was estimated by region.RESULTS. Travel times of
