The hypothesis that direct nursing hours correlate with the cost of a patient stay in intensive care was tested. One hundred and thirty-nine patients were studied and the data collected included: (a) direct nursing hours applied to each patient; (b) a daily TISS score: (c) a detailed costing of each patient (all costs are shown in N.Z.$). There was a strong correlation between the direct nursing hours and the total cost per patient (r2 = 0.98) (total cost = 54 x direct nursing hours + 344). Also a strong correlation existed between the total TISS scores and the total costs per patient (r2 = 0.96) (total cost = 67.13 x TISS). Direct nursing hours offer a relatively simple and logical method of allocating costs per patient.
对直接护理时长与重症监护患者住院费用相关的假设进行了检验。研究了139名患者，收集的数据包括：(a) 每位患者的直接护理时长；(b) 每日疾病严重度评分系统（TISS）得分；(c) 每位患者的详细成本核算（所有成本均以新西兰元显示）。直接护理时长与每位患者的总成本之间存在很强的相关性（r2 = 0.98）（总成本 = 54×直接护理时长 + 344）。此外，TISS总分与每位患者的总成本之间也存在很强的相关性（r2 = 0.96）（总成本 = 67.13×TISS）。直接护理时长提供了一种相对简单且合理的分配每位患者成本的方法。
