Data collected from a large county hospital in Miami, Florida were used to study the severity of illness (using the Case Mix Severity Index) and resource use (measured by average length of stay, procedures, and/or diagnostic tests performed) of undocumented persons from Dade Country, Florida in an inpatient setting. Compared with native-born populations and those with permanent residency status (insured by Medicaid or of uninsured status) admitted to the same hospital, undocumented immigrants had a higher Case Mix Severity Index but a lower adjusted average length of stay. Undocumented immigrants and uninsured residents of the United States had a similar number of adjusted procedures/ tests performed, but less than Medicaid beneficiaries. Policy issues are discussed.
研究人员利用从佛罗里达州迈阿密一家大型县医院收集的数据，在住院环境中研究了佛罗里达州戴德县无证人员的疾病严重程度（使用病例组合严重程度指数）和资源利用情况（通过平均住院时间、所进行的手术和/或诊断测试来衡量）。与在同一家医院住院的本土出生人群以及具有永久居留身份（由医疗补助保险或无保险）的人群相比，无证移民的病例组合严重程度指数更高，但调整后的平均住院时间更短。无证移民和美国无保险居民所进行的调整后的手术/测试数量相似，但少于医疗补助受益人群。文中还讨论了政策问题。
