Design of the HPTN 065 (TLC-Plus) study: A study to evaluate the feasibility of an enhanced test, link-to-care, plus treat approach for HIV prevention in the United States.

Background/Aims HIV continues to be a major public health threat in the United States, and mathematical modeling has demonstrated that the universal effective use of antiretroviral therapy among all HIV-positive individuals (i.e. the "test and treat" approach) has the potential to control HIV. However, to accomplish this, all the steps that define the HIV care continuum must be achieved at high levels, including HIV testing and diagnosis, linkage to and retention in clinical care, antiretroviral medication initiation, and adherence to achieve and maintain viral suppression. The HPTN 065 (Test, Link-to-Care Plus Treat [TLC-Plus]) study was designed to determine the feasibility of the "test and treat" approach in the United States. Methods HPTN 065 was conducted in two intervention communities, Bronx, NY, and Washington, DC, along with four non-intervention communities, Chicago, IL; Houston, TX; Miami, FL; and Philadelphia, PA. The study consisted of five components: (1) exploring the feasibility of expanded HIV testing via social mobilization and the universal offer of testing in hospital settings, (2) evaluating the effectiveness of financial incentives to increase linkage to care, (3) evaluating the effectiveness of financial incentives to increase viral suppression, (4) evaluating the effectiveness of a computer-delivered intervention to decrease risk behavior in HIV-positive patients in healthcare settings, and (5) administering provider and patient surveys to assess knowledge and attitudes regarding the use of antiretroviral therapy for prevention and the use of financial incentives to improve health outcomes. The study used observational cohorts, cluster and individual randomization, and made novel use of the existing national HIV surveillance data infrastructure. All components were developed with input from a community advisory board, and pragmatic methods were used to implement and assess the outcomes for each study component. Results A total of 76 sites in Washington, DC, and the Bronx, NY, participated in the study: 37 HIV test sites, including 16 hospitals, and 39 HIV care sites. Between September 2010 and December 2014, all study components were successfully implemented at these sites and resulted in valid outcomes. Our pragmatic approach to the study design, implementation, and the assessment of study outcomes allowed the study to be conducted within established programmatic structures and processes. In addition, it was successfully layered on the ongoing standard of care and existing data infrastructure without disrupting health services. Conclusion The HPTN 065 study demonstrated the feasibility of implementing and evaluating a multi-component "test and treat" trial that included a large number of community sites and involved pragmatic approaches to study implementation and evaluation.

Increasing leadership capacity for HIV/AIDS programmes by strengthening public health epidemiology and management training in Zimbabwe.

BACKGROUND: Increased funding for global human immunodeficiency virus prevention and control in developing countries has created both a challenge and an opportunity for achieving long-term global health goals. This paper describes a programme in Zimbabwe aimed at responding more effectively to the HIV/AIDS epidemic by reinforcing a critical competence-based training institution and producing public health leaders. METHODS: The programme used new HIV/AIDS programme-specific funds to build on the assets of a local education institution to strengthen and expand the general public health leadership capacity in Zimbabwe, simultaneously ensuring that they were trained in HIV interventions. RESULTS: The programme increased both numbers of graduates and retention of faculty. The expanded HIV/AIDS curriculum was associated with a substantial increase in trainee projects related to HIV. The increased number of public health professionals has led to a number of practically trained persons working in public health leadership positions in the ministry, including in HIV/AIDS programmes. CONCLUSION: Investment of a modest proportion of new HIV/AIDS resources in targeted public health leadership training programmes can assist in building capacity to lead and manage national HIV and other public health programmes.

The costs of HIV antiretroviral therapy adherence programs and impact on health care utilization.

From a trial comparing interventions to improve adherence to antiretroviral therapy-directly administered antiretroviral therapy (DAART) or an intensive adherence case management (IACM)-to standard of care (SOC), for HIV-infected participants at public HIV clinics in Los Angeles County, California, we examined the cost of adherence programs and associated health care utilization. We assessed differences between DAART, IACM, and SOC in the rate of hospitalizations, hospital days, and outpatient and emergency department visits during an average of 1.7 years from study enrollment, beginning November 2001. We assigned costs to health care utilization and program delivery. We calculated incremental costs of DAART or IACM v SOC, and compared those costs with savings in health care utilization among participants in the adherence programs. IACM participants experienced fewer hospital days compared with SOC (2.3 versus 6.7 days/1000 person-days, incidence rate ratio [IRR]: 0.34, 97.5% confidence interval [CI]: 0.13-0.87). DAART participants had more outpatient visits than SOC (44.2 versus 31.5/1000 person-days, IRR: 1.4; 97.5% CI: 1.01-1.95). Average per-participant health care utilization costs were $13,127, $8,988, and $14,416 for DAART, IACM, and SOC, respectively. Incremental 6-month program costs were $2,120 and $1,653 for DAART and IACM participants, respectively. Subtracting savings in health care utilization from program costs resulted in an average net program cost of $831 per DAART participant; and savings of $3,775 per IACM participant. IACM was associated with a significant decrease in hospital days compared to SOC and was cost saving when program costs were compared to savings in health care utilization.
