Syndromic management versus point-of-care, and lab based testing for Chlamydia and Gonorrhoea: A cost comparison

In this analysis, syndromic management was the least costly option. It requires skilled personnel but minimal supplies, equipment, and medication.Despite higher costs per case tested, the WHO has recommended etiological testing in countries that can afford it as part of its 2016-2021 strategy for global STI control.3 The added cost of etiological testing is possibly less than that of syndromic management if one considers the costs of caring for the many short- and long-term sequelae of 

High rates of death and loss to follow-up by 12 months of rifampicin resistant TB treatment in South Africa

Treatment success rates of rifampicin resistant (RR)/multi-drug resistant (MDR) tuberculosis (TB) in South Africa range from 43±48%, falling short of the World Health Organization's target of 75%. We present rates and assess predictors of attrition by 12 months on treatment.Prospective observational cohort analysis of adults (18 years) initiating RR/MDR-TB treatment from 01 March 2013 to 30 September 2016. Attrition was defined as a combination of death and loss to follow-up (LTFU; treatment 

Impact of Xpert MTB/RIF and decentralized care on linkage to care and drug-resistant tuberculosis treatment outcomes in Johannesburg, South Africa

We retrospectively matched adult patients diagnosed with laboratory-confirmed RR-TB in Johannesburg from 07/2011–06/2012 (early cohort) and 07/2013–06/2014 (late cohort) with records of patients initiating DR-TB treatment at one of the city’s four public sector treatment sites. We determine the proportion of persons diagnosed with RR-TB who initiated DR-TB treatment and report time to treatment initiation (TTI) before and after the implementation of Xpert MTB/RIF roll-out in Johannesburg, 

Third-Line Antiretroviral Therapy Program in the South African Public Sector: Cohort Description and Virological Outcomes

The World Health Organization recommends that antiretroviral therapy (ART) programs in resource-limited settings develop third-line ART policies. South Africa developed a national third-line ART program for patients who have failed both first-line non-nucleoside reverse transcriptase inhibitor–based ART and second-line protease inhibitor (PI)-based ART. We report on this 

Impact of a borderless sample transport network for scaling up viral load monitoring: results of a geospatial optimization model for Zambia

The World Health Organization recommends viral load (VL) monitoring at six and twelve months and then annually after initiating antiretroviral treatment for HIV. In many African countries, expansion of VL testing has been slow due to a lack of efficient blood sample transportation networks (STN). To assist Zambia in scaling up testing capacity, we modelled an optimal STN to minimize the cost of a national VL STN. The model optimizes a STN in Zambia for the anticipated 1.5 million VL tests that 

Effectiveness of interventions for unstable patients on antiretroviral therapy in South Africa: results of a cluster-randomised evaluation

As loss from HIV care is an ongoing challenge globally, interventions are needed for patients who don’t achieve or maintain ART stability. The 2015 South African National Adherence Guidelines (AGL) for Chronic Diseases include two interventions targeted at unstable patients: early tracing of patients who miss visits (TRIC) and enhanced adherence counselling (EAC). methods As part of a cluster-randomised evaluation at 12 intervention and 12 control clinics in four provinces, intervention sites 

How good are our guidelines? Four years of experience with the SAMJ’s AGREE II review of submitted clinical practice guidelines

In 2014, the SAMJ appointed an editorial subcommittee to review CPGs submitted for publication. This was in response to several concerns, including the global shift in CPG quality requirements, the potential effect of poor-quality CPGs on healthcare quality and cost, and the challenges South African (SA) CPG developers face in meeting new standards. This editorial reflects on the SAMJ CPG review subcommittee’s experience over the past 4 years and describes the value of more robust CPG 

Evaluating the integration of HIV selftesting into low-resource health systems: study protocol for a cluster-randomized control trial from EQUIP Innovations

Throughout sub-Saharan Africa HIV-testing rates remain low. Barriers to testing, such as inconvenient service hours and long wait times, lack of privacy, and fear of unwanted disclosure, continue to impede service utilization. HIV self-testing (HIVST) is one strategy that addresses these barriers and has been shown to increase use of HIV-testing when distributed through community-based settings. However, the scalability of HIVST is limited because it has yet to be fully integrated into 

Costs and cost-effectiveness of LEEP versus cryotherapy for treating cervical dysplasia among HIV-positive women in Johannesburg, South Africa

Cervical cancer incidence is significant in countries, such as South Africa, with high burdens of both HIV and human papillomavirus (HPV). Cervical cancer is largely preventable if dysplasia is diagnosed and treated early, but there is debate regarding the best approaches for screening and treatment, especially for low-resource settings. Currently South Africa provides Pap smears followed by colposcopic biopsy and LEEP if needed in its public health facilities. We estimated the costs and 

“My future is bright. . .I won’t die with the cause of AIDS”: ten-year patient ART outcomes and experiences in South Africa

South Africa is moving into a new era of HIV treatment with “treat all” policies where people may be on treatment for most of their lives. We need to understand treatment outcomes and facilitators of long-term antiretroviral treatment (ART) adherence and retention-in-care in the South African context. In one of the first studies to investigate long-term treatment outcomes in South Africa, we aimed to describe ten-year patient outcomes at a large public-sector HIV clinic in Johannesburg and 

Improved simplified clinical algorithm for identifying patients eligible for immediate initiation of antiretroviral therapy for HIV (SLATE II): protocol for a randomized evaluation

The SLATE II (Simplified Algorithm for Treatment Eligibility) study is an individually randomized evaluation of a clinical algorithm to reliably determine a patient’s eligibility for immediate ART initiation without waiting for laboratory results or additional clinic visits. It differs from the earlier SLATE I study in management of patients with symptoms of tuberculosis (under SLATE II these patients may be started on ART immediately) and other criteria for immediate initiation. SLATE II
