RESUMO
BACKGROUND: HIV testing, diagnosis and treatment programs have expanded globally, particularly in resource-limited settings. Diagnosis must be followed by determination of treatment eligibility and referral to care prior to initiation of antiretroviral treatment (ART). However, barriers and delays along these early steps in the treatment cascade may impede successful ART initiation. New strategies are needed to facilitate the treatment cascade. We evaluated the role of on site CD4+ T cell count phlebotomy services by nurses in facilitating pre-ART care in a community-based voluntary counseling and testing program (CBVCT) in rural South Africa. METHODS: We retrospectively evaluated CBVCT services during five continuous time periods over three years: three periods when a nurse was present on site, and two periods when the nurse was absent. When a nurse was present, CD4 count phlebotomy was performed immediately after HIV testing to determine ART eligibility. When a nurse was absent, patients were referred to their local primary care clinic for CD4 testing. For each period, we determined the proportion of HIV-positive community members who completed CD4 testing, received notification of CD4 count results, as well as the time to test completion and result notification. RESULTS: Between 2010 and 2013, 7213 individuals accessed CBVCT services; of these, 620 (8.6 %) individuals were HIV-positive, 205 (33.1 %) were eligible for ART according to South African national CD4 count criteria, and 78 (38.0 % of those eligible) initiated ART. During the periods when a professional nurse was available to provide CD4 phlebotomy services, HIV-positive clients were significantly more likely to complete CD4 testing than during periods when these services were not available (85.5 % vs. 37.3 %, p < 0.001). Additionally, when nurses were present, individuals were significantly more likely to be notified of CD4 results (60.6 % vs. 26.7 %, p <0.001). The time from HIV screening to CD4 test completion was also significantly shorter during nurse presence than nurse absence (median 8 days (IQR 4-19) vs. 35 days (IQR 15-131), p < 0.001). CONCLUSIONS: These findings indicate that in addition to CBVCT, availability of on site CD4 phlebotomy may reduce loss along the pre-ART care cascade and facilitate timely entry into HIV care.

BACKGROUND: TB preventative therapy (TPT) is crucial for reducing the burden of TB in endemic settings. We assessed stigma associated with TPT and the social groups from whom stigma was anticipated.METHODS: We conducted an anonymous cross-sectional survey of community-dwelling adults in rural South Africa. Descriptive statistics, exploratory factor analysis, χ² tests, Kruskal-Wallis tests, and Poisson regression were used to identify factors associated with TPT stigma.RESULTS: The mean age of the 104 participants was 35 years, 65% were female, and 26% had completed secondary school. The vast majority perceived stigma associated with TPT (71%; mean score 1.7, SD ± 1.4). Factor analysis identified a two-factor solution that explained 61.9% of the variance. Being single (P < 0.001), previously screened for TB (P = 0.04), worried about being infected by TB (P = 0.006), and interested in taking TPT (P = 0.01) were associated with higher perceived stigma scores. TPT stigma was perceived among 8%, 16%, and 66% of their family, friends, and other community members, respectively.CONCLUSION: The prevalence of TPT-related stigma in a rural South African community was high. Community members anticipated less stigma from family members compared to other social groups. Global expansion and implementation of TPT will require novel interventions, such as engaging patients´ families to support uptake and promote adherence.
