Michigan's Early and Periodic Screening, Diagnosis, and Treatment (EPSDT) program has screened more than 1.1 million Medicaid-eligible children since its inception in 1973. A study of its effects showed screening referral rates, but not medical costs, to be inversely related generally to the number of lifetime screenings received. Referrals from screening declined, on average, 4 to 9 percent as the number of lifetime screenings increased from 1 to 4. Medical costs for EPSDT participants were about 7 percent lower than medical costs for non-EPSDT participants when program costs were considered. Although the author acknowledges that a definitive study of EPSDT program effects has yet to be accomplished, he believes that modest gains are attributable to the program.
密歇根州的早期定期筛查、诊断与治疗（EPSDT）项目自1973年启动以来，已为超过110万名符合医疗补助条件的儿童进行了筛查。一项关于其效果的研究表明，筛查转诊率通常与终身筛查次数呈负相关，但医疗成本并非如此。随着终身筛查次数从1次增加到4次，筛查转诊率平均下降了4%至9%。在考虑项目成本的情况下，EPSDT参与者的医疗成本比非EPSDT参与者低约7%。尽管作者承认对EPSDT项目效果的最终研究尚未完成，但他认为该项目取得了一定成效。
