The Cost-Effectiveness and Clinical Impact of Standard, Voluntary HIV Testing In South Africa<\/p>\n
Abstract BackgroundThis study investigated the cost-effectiveness of voluntary\u00a0HIV testing strategies. These strategies included, testing once\u00a0in\u00a0a lifetime, testing after each five years, and yearly screening. This was in addition to the common practice, for identification of HIV infected persons. The author concluded that yearly voluntary\u00a0HIV testing,\u00a0in South Africa, was extremely cost-effective, notwithstanding the inadequate uptake as well as access in regard to care and treatment. The cost-effectiveness structure was valid and major areas of ambiguity were considered. <\/p>\n
Study objectivesThis study scrutinized three voluntary\u00a0HIV testing strategies in regard to their cost-effectiveness.\u00a0These strategies included, testing once\u00a0in\u00a0a lifetime, testing after each five years, and yearly screening. The study also focused on the common practice for identification of HIV infected persons. <\/p>\n
MethodsThe Setting of the study was located in South Africa, with a focus on primary care. The study was motivated by the rising concern in regard to the high HIV prevalence in South Africa. The national HIV prevalence in South Africa in the populace of individuals two years and above is projected at 10.8%. Women depict a higher prevalence at 13.3%, while the prevalence in men is projected at 8.2%. The study focused on children from the age of 2 to 14 years, and adults from the age of 15 to 49 years. Individuals above the age of 50 years were also considered. <\/p>\n
EthicsThe respondents were granted informed authority prior to their participation in the study. The researchers guaranteed this by notifying the relevant respondents about the rationale of this study. This included, the time limit, contents of the study, as well as the prospective risks. It also included the benefits significant to the study. The respondents were informed regarding the confidentiality of their identities. The researchers guaranteed this by refraining from linking the respondents to their responses to the survey.<\/p>\n
Methods of Analysis EmployedAnalytical approachThe basis of the analysis was on a HIV detection model of population-level model, referred to as the Cost-Effectiveness of Preventing AIDS Complications (CEPAC) International model. <\/p>\n
Efficacy DataClinical data was estimated through the use of data from\u00a0chosen\u00a0studies principally executed in South Africa, which\u00a0offered the\u00a0data on the patients\u2019 characteristics as well as epidemiology. The accuracy as well as the efficacy of the screening was\u00a0from related published studies. HIV prevalence was a fundamental input for this model.<\/p>\n
Cost DataEconomic analysis incorporated the costs of\u00a0HIV\u00a0screening,\u00a0HIV\u00a0care, regular care, out-patient, and in-patient hospital care, cluster of differentiation four (CD4)\u00a0count, as well as HIV\u00a0ribonucleic acid (RNA) test. The magnitude of resources and unit costs utilized were from the Clinton Foundation HIV\/AIDS Initiative 2009, the CTAC study, inventory of negotiated costs, and supplementary published sources.\u00a0These were\u00a0discounted at a yearly rate of 3%. The costs were in\u00a0US dollars.<\/p>\n
Analysis of AmbiguityA variety of substitute settings were considered,\u00a0with diverse assumptions\u00a0for chosen model inputs. Substitute values were obtained from published sources or the authors\u2019 postulations. <\/p>\n
ResultsConsidering the entire population, the estimated costs per individual were $2,330 with standard practice, $2,570 with testing once, $2,740 with testing after every five year period, and $3,330 with yearly testing. Quality-adjusted life expectancy rated 213.7 months with standard practice, 215.7 months with testing once, 216.8 months in the five-yearly testing, and 221.0 months in the yearly testing. The incremental investigation depicted that testing once\u00a0was imperceptibly dominated, since it was\u00a0less helpful and not as much in cost-effectiveness,\u00a0by five-yearly testing, while the incremental expenditure per Quality-adjusted life-years (QALYs) gained rated $1,570 in the five-yearly testing over\u00a0standard practice and $1,720 with yearly testing over five-yearly testing. The two strategies proved to be economically attractive in comparison to the South African per capita GDP threshold. <\/p>\n
The cost-effectiveness of testing was sustained in\u00a0a number of scenarios, in spite of presumptuous low baseline\u00a0incidence and prevalence of HIV. Antiretroviral therapy effectiveness was the parameter the depicted the strongest influence on the\u00a0cost-effectiveness ratios. Yearly screening was\u00a0generally, the most cost-effective stratagem. <\/p>\n
ConclusionThe authors in the study concluded that yearly voluntary\u00a0HIV\u00a0testing in\u00a0South Africa\u00a0was extremely cost-effective, in spite of limited access and uptake to HIV care and treatment.<\/p>\n
The authors acknowledged that their\u00a0outcomes were expected to be generalized outside South Africa,\u00a0in\u00a0nations with similar high\u00a0HIV prevalence.<\/p>\n","protected":false},"excerpt":{"rendered":"
