Survival and quality of life among HIV-positive people on antiretroviral therapy in Cambodia.

摘要

In 2004, Cambodia, a low-income country, undertook a rapid scale-up of free antiretroviral therapy (ART) through the public sector in order to respond to the need for treatment for those living with HIV/AIDS. A cohort of patients initiating ART in a provincial national hospital was set up at the beginning of the program to monitor the impact of treatment on patients. Patients provided information on behaviors through face-to-face interviews. Medical data were obtained from clinical files. Health-related quality of life (HRQOL) was assessed using the Medical Outcomes Study 21-Items Short Form (MOS SF-21). Patients were interviewed when initiating ART and followed up at 3 months, 6 months, and each consecutive 6 months thereafter. From March 2005 through January 2008, the cohort included 549 patients followed for a total of 645 person-years. The 4.0% of patients lost to follow-up were considered dead in the analysis. Incidence of mortality was 9.1 per 100 person-years, which is comparable to international standards. HRQOL subscale scores increased dramatically in the first year after initiating ART. The mean of overall HRQOL score rose from 63.0 at baseline to 81.1 at 1 year and 89.9 at 30 months of follow-up (chi(2) for trends p < 0.001). Simultaneously, the proportion of patients with full-time employment increased from 48.8% to 95.7%.We conclude that the rapid scaling-up of ART delivery in a resource poor Asian setting dramatically improved the survival and well-being of its beneficiaries, who in turn resumed productive lives within their communities.
