Factors that influence ambulatory care (visits to physicians and emergency rooms) and use of hospitals were investigated in a population of chronically ill, rural, low-income children. Rates of use for this population--a stratified random sample of 672 Medicaid-eligible children under age 17 years who lived in a 24-county area of northern Florida--were similar to those in a national study of chronically ill children. Further, the rates were shown to increase significantly as limitations to activity increased. Younger children and white children were also shown to have significantly higher use rates than older children and black children. Despite these associations, and those related to primary diagnoses, none of the analyses were able to explain much of the variation in the use of health care resources. The findings were similar to those of other studies; thus, the identification of the relatively small numbers of children who consume relatively large amounts of health care remains elusive.
在一群患有慢性病、居住在农村且低收入的儿童中，研究了影响门诊护理（看医生和去急诊室）及医院利用情况的因素。该人群是佛罗里达州北部24个县地区17岁以下符合医疗补助条件儿童的分层随机样本，其使用率与一项全国性慢性病儿童研究中的使用率相似。此外，随着活动受限程度增加，使用率显著上升。还发现年幼儿童和白人儿童的使用率明显高于年长儿童和黑人儿童。尽管存在这些关联以及与主要诊断相关的关联，但没有任何分析能够解释医疗保健资源使用方面的大部分差异。这些发现与其他研究的结果相似；因此，确定消耗相对大量医疗保健资源的相对少数儿童仍然很困难。
