Department of Motor Vehicles (DMV) facilities are assessed based on the proportion of patrons who consent to donate. To evaluate the individual characteristics that may influence donation consent, we analyzed the most recent transactions of 9,767,839 patrons of 203 Ohio DMVs between January 1, 2014 and November 17, 2018. Patron age, gender, donor designation, and DMV location were linked via patron zip codes with census tract data on race, ethnicity, income, and education. The Standardized Donor Designation Ratio (SDDR) (the observed number of donors at each DMV divided by the expected number of donors based on patron demographic characteristics) was calculated. Altogether 5,769,561 DMV patrons (59.1%) were designated as donors. Donor designation was independently associated with younger age, female gender, nonblack race, Hispanic ethnicity, and higher income. Across 203 DMVs, the percent donors ranged from 33% to 73%, and SDDRs ranged from 0.7 to 1.61. The correlation between the 2 measures demonstrated that 47% of the variation in SDDR was explained by percent donors. In conclusion, across DMVs there is substantial variation in organ donor designation rates. SDDRs that adjust for DMV patron characteristics may distinctly and more accurately describe individual DMV facility success in promoting organ donation.
机动车管理部门（DMV）设施是根据同意捐赠的顾客比例来评估的。为了评估可能影响捐赠同意的个体特征，我们分析了2014年1月1日至2018年11月17日期间俄亥俄州203个DMV的9767839名顾客的最新交易记录。顾客的年龄、性别、捐赠指定情况以及DMV地点通过顾客邮政编码与关于种族、民族、收入和教育的普查区数据相联系。计算了标准化捐赠指定率（SDDR）（每个DMV的实际捐赠者数量除以基于顾客人口统计学特征的预期捐赠者数量）。共有5769561名DMV顾客（59.1%）被指定为捐赠者。捐赠指定与年龄较小、女性、非黑人种族、西班牙裔民族以及较高收入独立相关。在203个DMV中，捐赠者百分比从33%到73%不等，SDDR从0.7到1.61不等。这两种衡量方法之间的相关性表明，SDDR中47%的变化可以由捐赠者百分比来解释。总之，在各个DMV之间，器官捐赠指定率存在很大差异。针对DMV顾客特征进行调整的SDDR可能会更清晰、更准确地描述各个DMV设施在促进器官捐赠方面的成效。
