The aim of this study is to describe patient demographics in a pediatric emergency department (PED) during low, average, and high daily census days.
Daily PED census, between January 1, 2006, and December 31, 2006, was categorized into very low, low, average, high, and very high quintiles. Variables of interest included acuity, age, health care coverage, and disposition. chi(2) analysis assessed the significance of differences in proportions of patient populations across the census quintiles.
An increasing proportion of younger children (<2 years of age) received care as daily volumes increased (P < .0001). Proportions of Medicaid and self-pay patient increased, whereas that of commercially insured patients decreased as daily census increased (P < .0001). The distributions of patient acuity level (63.1% nonurgent) and admission rate (12.8%) did not differ significantly cross census quintiles.
Younger children with self-pay and government-assisted health care coverage make up a greater proportion of children seen in a PED during high census days.
本研究旨在描述儿科急诊部（PED）在低、中、高日常患者人数日的患者人口统计学特征。
2006 年 1 月 1 日至 2006 年 12 月 31 日，将每日 PED 患者人数分为极低、低、中、高和极高五分位数。感兴趣的变量包括疾病严重程度、年龄、医疗保健覆盖范围和处置情况。卡方分析评估了患者人群比例在患者人数五分位数中的差异的显著性。
随着每日就诊人数的增加，年龄较小的（<2 岁）儿童接受治疗的比例增加（P<0.0001）。医疗补助和自费患者的比例增加，而商业保险患者的比例随着每日患者人数的增加而减少（P<0.0001）。患者疾病严重程度（63.1%非紧急）和住院率（12.8%）的分布在患者人数五分位数中没有显著差异。
在高患者人数日，具有自付和政府资助医疗保险的年龄较小的儿童在 PED 就诊的比例更高。
