This study analyses the relationship between the actual patient-related costs of care calculated for 145 patients admitted sequentially to an adult general intensive care unit and a number of factors obtained from a previously described consensus of opinion study. The factors identified in the study were suggested as potential descriptors for the casemix in an intensive care unit that could be used to predict the costs of care. Significant correlations between the costs of care and severity of illness, workload and length of stay were found but these failed to predict the costs of care with sufficient accuracy to be used in isolation to define isoresource groups in the intensive care unit. No associations between intensive care unit mortality, reason for admission and intensive and unit treatments and costs of care were found. Based on these results, it seems that casemix descriptors and isoresource groups for the intensive care unit that would allow costs to be predicted cannot be defined in terms of single factors.
本研究分析了为依次入住成人综合重症监护病房的145名患者计算的实际患者护理相关成本与从先前描述的共识意见研究中获得的若干因素之间的关系。该研究中确定的因素被认为是重症监护病房病例组合的潜在描述符，可用于预测护理成本。研究发现护理成本与疾病严重程度、工作量和住院时间之间存在显著相关性，但这些因素未能以足够的准确性预测护理成本，无法单独用于确定重症监护病房的等资源组。未发现重症监护病房死亡率、入院原因、重症监护和单位治疗与护理成本之间存在关联。基于这些结果，似乎无法根据单一因素来定义能够预测成本的重症监护病房病例组合描述符和等资源组。
