Five "big ticket" medical technologies (BTTs) in 1990 were compared in the 24 OECD countries in relation to population, the number of physicians, gross domestic product (GDP), and health care expenditures (HCE). Wide variations were observed between and within countries for all measures. Regression analysis revealed that HCE explains part of the variation in the distribution of computed tomography scanners (excluding Japan), magnetic resonance imaging units, and radiation therapy units (R2 between 0.40 and 0.69), but not extracorporeal shock wave lithotripters. To a lesser extent, GDP was also found to correlate with the distribution of these technologies, but no correlation was found with number of physicians. Other factors affecting the diffusion of these technologies are proposed for study.
1990年，对经济合作与发展组织（OECD）的24个国家的五项“大额”医疗技术（BTT）在人口、医生数量、国内生产总值（GDP）和医疗保健支出（HCE）方面进行了比较。在所有衡量标准上，国家之间和国家内部都观察到了很大差异。回归分析表明，医疗保健支出解释了计算机断层扫描仪（不包括日本）、磁共振成像设备和放射治疗设备分布变化的部分原因（R²在0.40至0.69之间），但体外冲击波碎石机除外。在较小程度上，还发现国内生产总值与这些技术的分布相关，但与医生数量无关。提出了其他影响这些技术传播的因素以供研究。
