Linkage to TB care: a qualitative study to understand linkage from the patients' perspective in the Western Cape Province, South Africa.

BACKGROUND Delayed linkage to tuberculosis (TB) treatment leads to poor patient outcomes and increased onward transmission. Between 12% and 25% of people diagnosed with TB are never linked to a primary health care facility for continued care. The TB health program is for creating processes that promote and facilitates easy access to care. We explored how TB patients experience TB services and how this influenced their choices around linkage to TB care and treatment. METHODS We enrolled 20 participants routinely diagnosed with TB in hospital or at primary health care facilities (PHC) in a high TB/HIV burdened peri-urban community in South Africa. Using the Western Cape Provincial Health Data centre (PHDC) which consolidates person-level clinical data, we used dates of diagnosis and treatment initiation to select participants who had been linked (immediately, after a delay, or never). Between June 2019 and January 2020, we facilitated in-depth discussions to explore both the participants' experience of their TB diagnosis and their journey around linking to TB care at a primary health care facility. We analysed the data using case descriptions. RESULTS Twelve of twenty (12/20) participants interviewed who experienced a delay linking were diagnosed at the hospital. Participants who experienced delays in linking or never linked explained this as a result of lack of information and support from health care providers. Unpleasant previous TB treatment episodes made it difficult to 'face' TB again and being uncertain of their TB diagnosis. In contrast, participants said the main motivator for linking was a personal will to get better. CONCLUSION The health care system, especially in hospitals, should focus on strengthening patient-centred care. Communication and clear messaging on TB processes is key, to prepare patients in transitioning from a hospital setting to PHC facilities for continuation of care. This should not just include a thorough explanation of their TB diagnosis but ensure that patients understand treatment processes. Former TB patients may require additional counselling and support to re-engage in care

Differences in health-related quality of life between HIV-positive and HIV-negative people in Zambia and South Africa: a cross-sectional baseline survey of the HPTN 071 (PopART) trial

Background The life expectancy of HIV-positive individuals receiving antiretroviral therapy (ART) is approaching that of HIV-negative people. However, little is known about how these populations compare in terms of health-related quality of life (HRQoL). We aimed to compare HRQoL between HIV-positive and HIV-negative people in Zambia and South Africa. Methods As part of the HPTN 071 (PopART) study, data from adults aged 18–44 years were gathered between Nov 28, 2013, and March 31, 2015, in large cross-sectional surveys of random samples of the general population in 21 communities in Zambia and South Africa. HRQoL data were collected with a standardised generic measure of health across five domains. We used β-distributed multivariable models to analyse differences in HRQoL scores between HIV-negative and HIV-positive individuals who were unaware of their status; aware, but not in HIV care; in HIV care, but who had not initiated ART; on ART for less than 5 years; and on ART for 5 years or more. We included controls for sociodemographic variables, herpes simplex virus type-2 status, and recreational drug use. Findings We obtained data for 19 750 respondents in Zambia and 18 941 respondents in South Africa. Laboratory-confirmed HIV status was available for 19 330 respondents in Zambia and 18 004 respondents in South Africa; 4128 (21%) of these 19 330 respondents in Zambia and 4012 (22%) of 18 004 respondents in South Africa had laboratory-confirmed HIV. We obtained complete HRQoL information for 19 637 respondents in Zambia and 18 429 respondents in South Africa. HRQoL scores did not differ significantly between individuals who had initiated ART more than 5 years previously and HIV-negative individuals, neither in Zambia (change in mean score −0·002, 95% CI −0·01 to 0·001; p=0·219) nor in South Africa (0·000, −0·002 to 0·003; p=0·939). However, scores did differ between HIV-positive individuals who had initiated ART less than 5 years previously and HIV-negative individuals in Zambia (−0·006, 95% CI −0·008 to −0·003; p<0·0001). A large proportion of people with clinically confirmed HIV were unaware of being HIV-positive (1768 [43%] of 4128 people in Zambia and 2026 [50%] of 4012 people in South Africa) and reported good HRQoL, with no significant differences from that of HIV-negative people (change in mean HRQoL score −0·001, 95% CI −0·003 to 0·001, p=0·216; and 0·001, −0·001 to 0·001, p=0·997, respectively). In South Africa, HRQoL scores were lower in HIV-positive individuals who were aware of their status but not enrolled in HIV care (change in mean HRQoL −0·004, 95% CI −0·01 to −0·001; p=0·010) and those in HIV care but not on ART (−0·008, −0·01 to −0·004; p=0·001) than in HIV-negative people, but the magnitudes of difference were small. Interpretation ART is successful in helping to reduce inequalities in HRQoL between HIV-positive and HIV-negative individuals in this general population sample. These findings highlight the importance of improving awareness of HIV status and expanding ART to prevent losses in HRQoL that occur with untreated HIV progression. The gains in HRQoL after individuals initiate ART could be substantial when scaled up to the population level

Women’s sexual scripting in the context of universal access to antiretroviral treatment—findings from the HPTN 071 (PopART) trial in South Africa

Background HIV treatment-based prevention modalities present new opportunities for women to make decisions around sex, intimacy, and prevention. The Universal test and treat (UTT) strategy, where widespread HIV testing is implemented and all people with HIV can access treatment, has the potential to change how sex is understood and HIV prevention incorporated into sexual relationships. We use the frame of sexual scripting to explore how women attribute meaning to sex relative to UTT in an HIV prevention trial setting. Exploring women’s sexual narratives, we explored how HIV prevention feature in the sexual scripts for women who had access to UTT in South Africa (prior to treatment guideline changes) and increased HIV prevention messaging, compared to places without widespread access to HIV testing and immediate access to treatment. Methods We employed a two-phased thematic analysis to explore longitudinal qualitative data collected from 71 women (18–35 years old) between 2016 and 2018 as part of an HIV prevention trial in the Western Cape Province, South Africa. Of the participants, 58/71 (82%) were from intervention communities while 13/71 (18%) lived in control communities without access to UTT. Twenty participants self-disclosed that they were living with HIV. Results We found no narrative differences between women who had access to UTT and those who did not. HIV and HIV prevention, including treatment-based prevention modalities, were largely absent from women’s thinking about sex. In their scripts, women idealised romantic sex, positioned sex as ‘about relationships’, and described risky sex as ‘other’. When women were confronted by HIV risk (for example, when a partner disclosed his HIV-positive status) this created a point of disjuncture between this new perception of risk and their accepted relationship scripts. Conclusion These findings suggest that HIV-negative women did not include their partners’ use of antiretroviral therapy in their sexual partnership choices. For these women, the preventive benefits of UTT are experienced passively—through community-wide viral suppression—rather than through their own behaviour change explicitly related to the availability of treatment as prevention. We propose that prevention-based modalities should be made available and supported and framed as an intervention to promote relationship well-being

Work and home productivity of people living with HIV in Zambia and South Africa

To compare number of days lost to illness or accessing healthcare for HIV-positive and HIV-negative individuals working in the informal and formal sectors in South Africa and Zambia.Design:As part of the HPTN 071 (PopART) study, data on adults aged 18-44 years were gathered from cross-sectional surveys of random general population samples in 21 communities in Zambia and South Africa. Data on the number of productive days lost in the last 3 months, laboratory-confirmed HIV status, labour force status, age, ethnicity, education, and recreational drug use was collected.Methods:Differences in productive days lost between HIV-negative and HIV-positive individuals ('excess productive days lost') were estimated with negative binomial models, and results disaggregated for HIV-positive individuals after various durations on antiretroviral treatment (ART).Results:From samples of 19330 respondents in Zambia and 18004 respondents in South Africa, HIV-positive individuals lost more productive days to illness than HIV-negative individuals in both countries. HIV-positive individuals in Zambia lost 0.74 excess productive days [95% confidence interval (CI) 0.48-1.01; P<0.001] to illness over a 3-month period. HIV-positive in South Africa lost 0.13 excess days (95% CI 0.04-0.23; P=0.007). In Zambia, those on ART for less than 1 year lost most days, and those not on ART lost fewest days. In South Africa, results disaggregated by treatment duration were not statistically significant.Conclusion:There is a loss of work and home productivity associated with HIV, but it is lower than existing estimates for HIV-positive formal sector workers. The findings support policy makers in building an accurate investment case for HIV interventions

Reducing initial loss to follow up among people with bacteriologically confirmed tuberculosis: LINKEDin, a quasi-experimental study in South Africa

Every person diagnosed with tuberculosis (TB) needs to initiate treatment. The WHO estimated 61% of people who developed TB in 2021 were included in a TB treatment registration system. Initial loss to follow up (ILTFU) is the loss of persons to care between diagnosis and treatment initiation/registration. LINKEDin, a quasi-experimental study, evaluated the effect of two interventions (hospital-recording and an alert-and-response patient management intervention) in six sub-districts across three high-TB burden provinces of South Africa. Using integrated electronic reports, we identified all persons diagnosed with TB (Xpert MTB/RIF positive) in hospital and at primary healthcare facilities. We prospectively determined linkage to care at 30 days after TB diagnosis. We calculated the risk of ILTFU during the baseline and intervention periods and the relative risk reduction in ILTFU between these periods. We found a relative reduction in ILTFU of 42.4% (95%CI:28.5,53.7) in KwaZulu Natal (KZN) and 22.3% (95%CI:13.3,30.4) in the Western Cape (WC) with no significant change in Gauteng. In KZN and the WC, the relative reduction in ILTFU appeared greater in sub-districts where the alert-and-response patient management intervention was implemented; KZN (49.3% (95%CI:32.4,62) vs 32.2% (95%CI:5.4,51.4)); and WC (34.2% (95%CI:20.9,45.3) vs 13.4% (95%CI:0.7,24.4)). We reported a notable reduction in ILTFU in two provinces using existing routine health service data and applying a simple intervention to trace and recall those not linked to care. TB programs need to consider ILTFU as a priority and develop interventions specific to their context to ensure improved linkage to care

Factors impacting on adherence to antiretroviral treatment at False Bay Hospital

Thesis (MPhil)--Stellenbosch University, 2013.ENGLISH ABSTRACT: The purpose of this research was to investigate factors impacting on adherence to antiretroviral treatment on people living with HIV and to further explore challenges they come across with adherence. The primary focus of this investigation relates to the following four themes. (i)To evaluate demographic factors such as age, gender and socio-economic factors and the influence they have or contribution to adherence, in correlation with the effects of cultural and health beliefs in this context. (ii) To establish the significance of counselling and review critical challenging issues that needs consideration. (iii) To investigate the nature of reception (negative or ( positive) that patient receives in this local health facility, including the nature of perceived youth friendliness as it may act as a deterrent for confidentiality with regard to referrals. (iv) To determine perceived relationship between health care providers and patients, by patients in terms of support system, referral systems and the prevention of stigma and discrimination. This study comprises of the literature analysis on adherence globally and in the South African context, reviewing the challenges experienced by many South Africans and people living in this country. The study was implemented at a Government’s facility in a health care sector “False Bay Hospital” in the Western Cape, through one focus group and ten semi-structured interviews with patients. The findings of the study reveal that stigma and discrimination is one of the leading causes to poor adherence on antiretroviral treatment including social problems experienced by PLWA. Support and counselling programmes provided at False Bay Hospital were significant but did not necessarily help PLWA in other challenges they came across with. This study also demonstrated the importance of health education and good relationship with patience has a positive effect towards adherence and improves chances of better health.AFRIKAANSE OPSOMMING: Die doel van hierdie navorsing was om faktore te ondersoek wat ’n impak het op die nakoming van antiretrovirale behandeling deur mense wat met MIV leef en om voorts uitdagings te ondersoek wat hulle met betrekking tot nakoming ervaar. Die hooffokus van hierdie ondersoek hou met die volgende vier temas verband. (i) Om demografiese faktore soos ouderdom, geslag en sosio-ekonomiese faktore en die invloed daarvan op of bydrae tot nakoming te ondersoek met betrekking tot die invloed van kulturele en gesondheidsoortuigings in hierdie verband. (ii) Om die noodsaaklikheid van berading te bepaal en om kritieke uitdagings te ondersoek wat oorweeg moet word. (iii) Om die aard van ontvangs (negatief of positief) wat pasiënte in hierdie plaaslike gesondheidsfasiliteit ontvang, te ondersoek, met inbegrip van die aard van waargenome vriendelikheid van die jeug, aangesien dit ’n afskrikmiddel vir vertroulikheid met betrekking tot verwysings kan wees. (iv) Om waargenome verhoudings tussen gesondheidsorgverskaffers en pasiënte deur pasiënte met betrekking tot ondersteuningstelsels, verwysingstelsels en die voorkoming van stigma en diskriminasie te bepaal. Hierdie studie bestaan uit ’n literatuurstudie oor nakoming in die internasionale asook Suid-Afrikaanse konteks, met ’n oorsig van die uitdagings wat deur talle Suid-Afrikaners en mense wat in hierdie land woon, ervaar word. Die studie is by ’n regeringsfasiliteit, Valsbaai Hospitaal, in ’n gesondheidsorgsektor in die Wes-Kaap uitgevoer deur een fokusgroepbespreking en tien semigestruktureerde onderhoude met pasiënte. Die bevindings van die studie toon dat stigma en diskriminasie die grootste oorsake van swak nakoming van antiretrovirale behandeling is, met inbegrip van maatskaplike probleme wat ervaar word deur mense wat met vigs leef. Ondersteunings- en beradingsprogramme wat by Valsbaai Hospitaal gebied word, is beduidend, maar bied nie noodwendig hulp aan mense wat met vigs leef wat ander uitdagings waarvoor hulle te staan kom, betref nie. Die studie toon ook die belang van gesondheidsopvoeding en dat goeie verhoudings met pasiënte ’n positiewe uitwerking op nakoming het en die kanse op beter gesondheid verhoog

"Being seen" at the clinic: Zambian and South African health worker reflections on the relationship between health facility spatial organisation and items and HIV stigma in 21 health facilities, the HPTN 071 (PopART) study.

Health workers in 21 government health facilities in Zambia and South Africa linked spatial organisation of HIV services and material items signifying HIV-status (for example, coloured client cards) to the risk of People Living with HIV (PLHIV) 'being seen' or identified by others. Demarcated HIV services, distinctive client flow and associated-items were considered especially distinguishing. Strategies to circumvent any resulting stigma mostly involved PLHIV avoiding and/or reducing contact with services and health workers reducing visibility of PLHIV through alterations to structures, items and systems. HIV spatial organisation and item adjustments, enacting PLHIV-friendly policies and wider stigma reduction initiatives could combined reduce risks of identification and enhance the privacy of health facility space and diminish stigma

Cost and cost-effectiveness of a universal HIV testing and treatment intervention in Zambia and South Africa: evidence and projections from the HPTN 071 (PopART) trial

Background The HPTN 071 (PopART) trial showed that a combination HIV prevention package including universal HIV testing and treatment (UTT) reduced population-level incidence of HIV compared with standard care. However, evidence is scarce on the costs and cost-effectiveness of such an intervention. Methods Using an individual-based model, we simulated the PopART intervention and standard care with antiretroviral therapy (ART) provided according to national guidelines for the 21 trial communities in Zambia and South Africa (for all individuals aged >14 years), with model parameters and primary cost data collected during the PopART trial and from published sources. Two intervention scenarios were modelled: annual rounds of PopART from 2014 to 2030 (PopART 2014–30; as the UNAIDS Fast-Track target year) and three rounds of PopART throughout the trial intervention period (PopART 2014–17). For each country, we calculated incremental cost-effectiveness ratios (ICERs) as the cost per disability-adjusted life-year (DALY) and cost per HIV infection averted. Cost-effectiveness acceptability curves were used to indicate the probability of PopART being cost-effective compared with standard care at different thresholds of cost per DALY averted. We also assessed budget impact by projecting undiscounted costs of the intervention compared with standard care up to 2030. Findings During 2014–17, the mean cost per person per year of delivering home-based HIV counselling and testing, linkage to care, promotion of ART adherence, and voluntary medical male circumcision via community HIV care providers for the simulated population was US$6·53 (SD 0·29) in Zambia and US$7·93 (0·16) in South Africa. In the PopART 2014–30 scenario, median ICERs for PopART delivered annually until 2030 were $2111 (95$3248 (2472–3963) per HIV infection averted in South Africa; and $593 (95$645 (538–757) per DALY averted in South Africa. In the PopART 2014–17 scenario, PopART averted one infection at a cost of $1318 (1098–1591) in Zambia and$2236 (1601–2916) in South Africa, and averted one DALY at $258 (225–298) in Zambia and$326 (266–391) in South Africa, when outcomes were projected until 2030. The intervention had almost 100% probability of being cost-effective at thresholds greater than $700 per DALY averted in Zambia, and greater than$800 per DALY averted in South Africa, in the PopART 2014–30 scenario. Incremental programme costs for annual rounds until 2030 were $46·12 million (for a mean of 341 323 people) in Zambia and$30·24 million (for a mean of 165 852 people) in South Africa. Interpretation Combination prevention with universal home-based testing can be delivered at low annual cost per person but accumulates to a considerable amount when scaled for a growing population. Combination prevention including UTT is cost-effective at thresholds greater than $800 per DALY averted and can be an efficient strategy to reduce HIV incidence in high-prevalence settings

Differences in health-related quality of life between HIV-positive and HIV-negative people in Zambia and South Africa: a cross-sectional baseline survey of the HPTN 071 (PopART) trial

HRQoL scores did not differ significantly between individuals who had initiated ART more than 5 years previously and HIV-negative individuals, neither in Zambia (change in mean score −0·002, 95% CI −0·01 to 0·001; p=0·219) nor in South Africa (0·000, −0·002 to 0·003; p=0·939). However, scores did differ between HIV-positive individuals who had initiated ART less than 5 years previously and HIV-negative individuals in Zambia (−0·006, 95% CI −0·008 to −0·003; p<0·0001).

In South Africa, HRQoL scores were lower in HIV-positive individuals who were aware of their status but not enrolled in HIV care (change in mean HRQoL −0·004, 95% CI −0·01 to −0·001; p=0·010) and those in HIV care but not on ART (−0·008, −0·01 to −0·004; p=0·001) than in HIV-negative people, but the magnitudes of difference were small. Interpretation: ART is successful in helping to reduce inequalities in HRQoL between HIV-positive and HIV-negative individuals in this general population sample. These findings highlight the importance of improving awareness of HIV status and expanding ART to prevent losses in HRQoL that occur with untreated HIV progression. The gains in HRQoL after individuals initiate ART could be substantial when scaled up to the population level.
