The CDC recommends routine voluntary HIV testing of all patients 13-64 years of age. Despite this recommendation, HIV testing rates are low even among those at identifiable risk, and many patients do not return to receive their results.
To examine the costs and benefits of strategies to improve HIV testing and receipt of results.
Cost-effectiveness analysis based on a Markov model. Acceptance of testing, return rates, and related costs were derived from a randomized trial of 251 patients; long-term costs and health outcomes were derived from the literature. SETTING/TARGET POPULATION: Primary-care patients with unknown HIV status.
Comparison of three intervention models for HIV counseling and testing: Model A = traditional HIV counseling and testing; Model B = nurse-initiated routine screening with traditional HIV testing and counseling; Model C = nurse-initiated routine screening with rapid HIV testing and streamlined counseling.
Life-years, quality-adjusted life-years (QALYs), costs and incremental cost-effectiveness.
Without consideration of the benefit from reduced HIV transmission, Model A resulted in per-patient lifetime discounted costs of $48,650 and benefits of 16.271 QALYs. Model B increased lifetime costs by $53 and benefits by 0.0013 QALYs (corresponding to 0.48 quality-adjusted life days). Model C cost $66 more than Model A with an increase of 0.0018 QALYs (0.66 quality-adjusted life days) and an incremental cost-effectiveness of $36,390/QALY. When we included the benefit from reduced HIV transmission, Model C cost $10,660/QALY relative to Model A. The cost-effectiveness of Model C was robust in sensitivity analyses.
In a primary-care population, nurse-initiated routine screening with rapid HIV testing and streamlined counseling increased rates of testing and receipt of test results and was cost-effective compared with traditional HIV testing strategies.

    • "A greater number of patients agreed to testing with the nurse-initiated screening (89.33%) as compared with the traditional model. A subsequent analysis of the same study concluded that the model with rapid testing and nurse-initiated screening was the most cost effective (Sanders et al., 2010). Consistent with Anaya and colleagues' (2008) findings, Cunningham and colleagues (2009) found positive results with greater patient acceptability of opt-out testing in an urban community health center when nurses offered the screening compared to physicians.

    ABSTRACT: The Centers for Disease Control and Prevention (CDC) expanded HIV screening of adults ages 13-64 years in 2006 from risk based to routine. Early detection and treatment improve patient outcomes and prevent disease transmission. This article describes a pilot program in which nurses in an adult inpatient unit at an acute care hospital offer HIV testing to all patients ages 18-64 upon admission through standing orders. The pilot, Standing Orders for Routine Testing (SORT), is a response to changes in state law and regulations in the majority of states including Rhode Island, which have occurred following the CDC policy change. The SORT pilot involves collaboration with interdisciplinary partners and education of unit nurses.

    • "It is estimated that a POC test of moderate sensitivity (63%) combined with immediate treatment on-site may lead to the treatment of more infected individuals than an ultra-sensitive and specific NAAT alone when patient return is low [8]. Moreover, counselling messages are most efficient when a diagnosis can be communicated during the same consultation [9]. These advantages are relevant for industrialized countries as well, even if POC tests have a lower sensitivity than standard NAAT. "

    ABSTRACT: In general, point-of-care (POC) tests for Chlamydia trachomatis (Ct) show disappointing test performance, especially disappointing sensitivity results. However, one study sponsored by the manufacturer (Diagnostics for the Real World) reported over 80% sensitivity with their Chlamydia Rapid Test (CRT). We evaluated the performance of this CRT in a non-manufacturer-sponsored trial. Between July 2009 and February 2010, we included samples from 912 women in both high- and low-risk clinics for sexually transmitted infections (STIs) in Paramaribo, Suriname. Sensitivity, specificity, positive- and negative predictive values (PPV and NPV) for CRT compared to NAAT (Aptima, Gen-Probe) were determined. Quantitative Ct load and human cell load were determined in all CRT and/or NAAT positive samples. CRT compared to NAAT showed a sensitivity and specificity of 41.2% (95% CI, 31.9%-50.9%) and 96.4% (95% CI, 95.0%-97.5%), respectively. PPV and NPV were 59.2% (95% CI, 47.5%-70.1%) and 92.9% (95% CI, 91.0%-94.5%), respectively. Quantitative Ct bacterial load was 73 times higher in NAAT-positive/CRT-positive samples compared to NAAT-positive/CRT-negative samples (p<0.001). Human cell load did not differ between true-positive and false-negative CRT results (p = 0.835). Sensitivity of CRT in samples with low Ct load was 12.5% (95% CI, 5.2%-24.2%) and in samples with high Ct load 73.5% (95% CI, 59.9%-84.4%). The sensitivity of CRT for detecting urogenital Ct in this non-manufacturer-sponsored study did not meet the expectations as described previously. The CRT missed samples with a low Ct load. Improved POC are needed as meaningful diagnostic to reduce the disease burden of Ct.

    ABSTRACT: Clin Microbiol Infect 2010; 16: 1070–1076 We review the growing number of economic evaluations of individual point-of-care (POC) tests for diagnosis of infectious diseases in resource-limited settings that use either cohort studies or mathematical models. We focus on studies that evaluate POC diagnostic tests for the control of human immunodeficiency virus (HIV) and malaria, tools that are central to the WHO prevention guidelines for infectious diseases in developing countries. Although rapid diagnostic tests for HIV and malaria seem to be cost-effective in these standard analyses, these do not take into account the reduction in patients’ waiting time and the number of clinic visits required to receive results, or future benefits from the reduction in antimalarial drug pressure. Those additional cost reductions would be considerably greater with POC rapid tests, and the cost-effectiveness of POC tests would therefore be improved. Findings from cost-effectiveness analyses suggest that, despite the relatively small additional cost incurred, decision-makers should strongly consider using POC tests throughout or during parts of HIV and malaria epidemics, where this is feasible in terms of local human resources and logistical conditions.
