An evaluation of a choice architecture-based intervention on prescribing of TB preventive treatment to people living with HIV in southern Africa (the CAT study)
INTRODUCTION: While highly effective for reducing the risk of tuberculosis (TB) disease, TB preventive treatment (TPT) is underused among people living with HIV (PWH). We evaluated the effectiveness of a behavioural economics-based choice architecture approach to increase facility-level TPT prescribing to PWH in Malawi, Mozambique and Zimbabwe. METHODS: We conducted a cluster-randomised trial within the IMPAACT4TB 3HP rollout, in which 57 healthc…
Contextualizing and optimizing novel strategies to improve the latent TB continuum of care
Tuberculosis (TB) causes 1 in 3 deaths among people living with HIV (PLHIV). Diagnosing and treating latent tuberculosis infection (LTBI) is critical to reducing TB incidence and mortality. Blood-based screening tests (e.g., QuantiFERON-TB Gold Plus (QFT+)) and shorter-course TB preventive therapy (TPT) regimens such as 3HP (3 months weekly isoniazid-rifapentine) hold significant promise to improve TB outcomes. We qualitatively explored barriers …
Social support needs of HIV-positive individuals reentering community settings from correctional facilities in Johannesburg, South Africa
Social networks and social support are important factors in medication adherence among people living with HIV (PLWH). Social networks can provide emotional, logistic, and material support leading to increased overall engagement in care. Certain populations of PLWH may have more limited access to social support, including those reentering community settings from correctional facilities. During periods of incarceration, social connections with fami…
Assessing eligibility for differentiated service delivery, HIV services utilization and virologic outcomes of adult HIV-infected patients in Sierra Leone
Background There are limited data to help guide implementation of differentiated HIV service delivery (DSD) in resource-limited settings in sub-Saharan Africa.Objectives This pre-implementation study sought to assess the proportion of patients eligible for DSD and HIV services utilization, as well as risk factor analysis of virologic failure in Sierra Leone.Methods We conducted a retrospective study of adult HIV-infected patients aged 18 years an…
Observational study of continuity of HIV care following release from correctional facilities in South Africa
The results of our study are the first description of retention in care following correctional facility release from an African setting and indicate high levels of attrition during the transition from correctional facility to community care. Initiating ART within a correctional facility did not impair post-release linkage to care
Youth Preferences for HIV Testing in South Africa
Is HIV Post-test Counselling Aligned with Universal Test and Treat Goals? A Qualitative Analysis of Counselling Session Content and Delivery in South Africa
Enhancing value and lowering costs of care
While interventions to improve HIV linkage and retention in care exist, none have demonstrated results sufficient to reach UNAIDS 90-90-90 goals. We explored values and costs of seeking clinical care through testing three strategies to improve linkage to care: Point of care CD4 testing alone (POC-CD4), POC-CD4 combined with transportation support and combined with care facilitation. We conducted in-depth interviews with participants and transcrib…

Perceptions of Value and Cost of HIV Care Engagement Following Diagnosis in South Africa
Tuberculosis active case finding
We identified undiagnosed pulmonary TB cases among drivers but at a level that may be insufficient to justify systematic case finding in this population considering the poor uptake
Psychological Distress among Recent Russian Immigrants in the United States
Background: The purpose of this study was to examine the psychological status of Russian immigrants who have recently come to the United States. Aims: The project included creation of a Russian version of the Hopkins Symptom Checklist-25 (HSCL-25) in order to identify anxiety and depression in members of the Russian-speaking immigrant population. Methods: Translation and adaptation included (a) cross-cultural adaptation; (b) translation; (c) pre-…
