As a complement to a number of existing cost-containment programs, Blue Cross of Maryland developed a length of stay (LOS) review process for its members. The method is based on the premise that the utilization of hospital inpatient services varies along two major dimensions--service duration (expressed in days of hospital stay) and service intensity (expressed as the proportion of ancillary service charges to total charges). Composed of seven steps, the method statistically analyzes the relationship between LOS and ancillary service charges as a proportion of total charges for selected diagnoses. The attempt to monitor two dimensions of inpatient care simultaneously is a departure from existing utilization review methods. Besides a detailed description of each step in this methodology, this article presents preliminary findings from a pilot study conducted in eight Baltimore hospitals.
作为对许多现有成本控制计划的补充，马里兰蓝十字公司为其会员制定了住院时长（LOS）审查流程。该方法基于这样一个前提，即医院住院服务的利用率在两个主要维度上有所不同——服务时长（以住院天数表示）和服务强度（以辅助服务费用占总费用的比例表示）。该方法由七个步骤组成，它对选定诊断的住院时长与辅助服务费用占总费用的比例之间的关系进行统计分析。同时监测住院护理的两个维度的尝试与现有的利用率审查方法不同。除了详细描述该方法的每个步骤外，本文还介绍了在巴尔的摩八家医院进行的一项试点研究的初步结果。
