The long-term objective of this study is to help understand the impact patients in early stages of HIV infection have on health service delivery systems. The specific objective of this study is to assess the 1990-2 direct medical care costs and utilization of an estimated 250 patients at Group Health Cooperative of Puget Sound (GHC) who are HIV positive and are actively receiving treatment. Since the management of HIV positive patients has shifted to more treatment during the asymptomatic and mildly symptomatic early stages of the infection, existing cost and utilization studies which focus only on pre-Class IV HIV conditions (frank AIDS) no longer give a complete picture of HIV-related care. A non-experimental control group design will be used for the analysis. Cost and utilization data from the study sample will be compared for pre- Class IV patients and two control groups (all of GHC's enrollees who do not have HIV/AIDS conditions and are within the same age range as the study and Class IV HIV (AIDS) enrollees. Since all the utilization and cost variables are continuous, a linear regression analysis will be used to determine each group;s cost function. The independent variables are the costs of services (i.e., radiology, laboratory, pharmacy, hospital days, long-term care days, etc.) and the dependent variable is total cost. The cost for each service will be calculated by multiplying the utilization by the standard GHC cost for each service. GHC's accounting system allows tracking of variable and overhead costs of each service for each patient. A cross-sectional time series analysis will be used to predict the increase in cost and utilization of services attributable to HIV infection from identified HIV infection through Class IV stage to death. The analysis will characterize how the distribution of services changes with the progression of the disease, and how services compare with those utilized by age/sex matched control groups.

这项研究的长期目标是帮助了解 艾滋病毒感染早期阶段的病人对保健服务的提供有 系统. 本研究的具体目标是评估1990-2年 估计250名病人的直接医疗费用和使用情况 在普吉特海湾团体健康合作社（GHC），艾滋病毒阳性， 正在积极接受治疗。 自从管理艾滋病毒阳性 患者在无症状和轻度 感染的早期症状、现有成本和利用率 仅关注IV类前艾滋病毒状况的研究（坦率的艾滋病） 更长的时间提供艾滋病毒相关护理的完整画面。 将使用非实验对照组设计进行分析。 研究样本的成本和利用率数据将比较， IV级患者和两个对照组（所有GHC的注册者） 没有艾滋病毒/艾滋病的条件，并在同一年龄范围内的 研究和第四类艾滋病毒（艾滋病）入学者。 由于所有的利用率和 成本变量是连续的，将使用线性回归分析 以确定每个组的成本函数。 独立变量是 服务的成本（即，放射学、实验室、药房、医院 日、长期护理日等）因变量是总量 成本 每项服务的成本将通过乘以 按每项服务的标准GHC费用计算的利用率。 GHC的会计 系统允许跟踪每项服务的可变成本和间接成本， 每一个病人。 将使用横截面时间序列分析， 预测由于以下原因而导致的服务成本和利用率的增加 HIV感染从确诊的HIV感染到IV类阶段， 死亡 分析将描述服务分布的变化情况 随着疾病的进展，以及服务如何与那些 由年龄/性别匹配的对照组使用。
