CHESS (the Comprehensive Health Enhancement Support System) is an interactive, computer-based system to support people facing AIDS/HIV Infection and other health-related crises or concerns. CHESS provides information, referral to service providers, support in making tough decisions and networking to experts and others facing the same concerns. CHESS is designed to improve access to health and human services for people who would otherwise face psychological, social, economic or geographic barriers to receiving services. CHESS has been evaluated in a random-assignment study with over 200 men and women living with AIDS and HIV infection. When CHESS was placed in subjects' homes for 3-6 months, use of CHESS was extremely heavy, with the average subject using CHESS 138 times for 39 hours. Compared with a control group which did not receive CHESS, subjects who used CHESS reported significantly higher quality of life in several dimensions, including social support and cognitive functioning. Users also reported significant reductions in some types of health care costs, especially inpatient services (hospitalizations). All segments of the study population used and benefited from CHESS, including women, minorities and those subjects with lower levels of education. Thus, CHESS appears to be an effective means of delivering education and support to the diverse populations which are affected by AIDS and HIV infection.
CHESS（综合健康强化支持系统）是一个基于计算机的交互式系统，旨在为面临艾滋病/艾滋病毒感染以及其他与健康相关危机或问题的人群提供支持。CHESS提供信息、转介服务提供商、协助做出艰难决策以及与面临相同问题的专家和其他人建立联系。CHESS旨在改善那些否则将面临心理、社会、经济或地理障碍而无法获得服务的人群获得健康和人类服务的机会。CHESS已在一项针对200多名艾滋病和艾滋病毒感染者的随机分配研究中进行了评估。当CHESS被放置在受试者家中3至6个月时，其使用频率极高，平均每位受试者使用CHESS 138次，时长达到39小时。与未接受CHESS的对照组相比，使用CHESS的受试者在包括社会支持和认知功能在内的多个维度上报告的生活质量显著更高。用户还报告说某些类型的医疗保健费用大幅降低，尤其是住院服务（住院治疗）费用。研究人群的所有群体都使用了CHESS并从中受益，包括女性、少数族裔以及教育水平较低的受试者。因此，CHESS似乎是向受艾滋病和艾滋病毒感染影响的不同人群提供教育和支持的有效手段。
