To understand the sources of the high costs of neonatal intensive care, financial and medical information on 1,185 admissions to an intensive care nursery was gathered. Multiple regression analysis showed that a significant portion of the variation in individual costs was explained by three measures of risk: low birth weight, surgical intervention, and assisted ventilation. There was a highly skewed distribution of costs. Nearly half of all admissions had none of the above risk factors, had an average cost of about $2,000, and accounted for only 13% of the total costs for the whole sample. In contrast, less than one quarter of the admissions had two or more of the risk factors, had an average cost of $19,800, and accounted for nearly 60% of the total costs. Models that predict costs and length of stay on a basis of seven risk factors were developed to allow for differences in patient populations.
为了解新生儿重症监护高成本的来源，收集了1185例入住重症监护病房的财务和医疗信息。多元回归分析表明，个体成本差异的很大一部分可由三个风险指标来解释：低出生体重、手术干预和辅助通气。成本分布严重不均衡。几乎一半的入院病例没有上述任何风险因素，平均成本约为2000美元，仅占整个样本总成本的13%。相比之下，不到四分之一的入院病例有两个或更多风险因素，平均成本为19800美元，占总成本的近60%。基于七个风险因素建立了预测成本和住院时间的模型，以考虑不同患者群体之间的差异。
