Implementing 'universal' access to antiretroviral treatment in South Africa: a scoping review on research priorities.

'Universal' access to antiretroviral treatment (ART) has become the global standard for treating people living with HIV and achieving epidemic control; yet, findings from numerous 'test and treat' trials and implementation studies in sub-Saharan Africa suggest that bringing 'universal' access to ART to scale is more complex than anticipated. Using South Africa as a case example, we describe the research priorities and foci in the literature on expanded ART access. To do so, we adapted Arksey and O'Malley's six-stage scoping review framework to describe the peer-reviewed literature and opinion pieces on expanding access to ART in South Africa between 2000 and 2017. Data collection included systematic searches of two databases and hand-searching of a sub-sample of reference lists. We used an adapted socio-ecological thematic framework to categorize data according to where it located the challenges and opportunities of expanded ART eligibility: individual/client, health worker-client relationship, clinic/community context, health systems infrastructure and/or policy context. We included 194 research articles and 23 opinion pieces, of 1512 identified, addressing expanded ART access in South Africa. The peer-reviewed literature focused on the individual and health systems infrastructure; opinion pieces focused on changing roles of individuals, communities and health services implementers. We contextualized our findings through a consultative process with a group of researchers, HIV clinicians and programme managers to consider critical knowledge gaps. Unlike the published literature, the consultative process offered particular insights into the importance of researching and intervening in the relational aspects of HIV service delivery as South Africa's HIV programme expands. An overwhelming focus on individual and health systems infrastructure factors in the published literature on expanded ART access in South Africa may skew understanding of HIV programme shortfalls away from the relational aspects of HIV services delivery and delay progress with finding ways to leverage non-medical modalities for achieving HIV epidemic control.

Retention in care and factors critical for effectively implementing antiretroviral adherence clubs in a rural district in South Africa.

INTRODUCTION: Differentiated models of care that include referral of antiretroviral treatment (ART) clients to adherence clubs are an important strategy to help clinics manage increased number of clients living with HIV in resource-constrained settings. This study reported on (i) clinical outcomes among ART clients attending community-based adherence clubs and (ii) experiences of adherence clubs and perceptions of factors key to successful adherence club implementation among clients and healthcare workers. METHODS: A retrospective cohort analysis of routine data and a descriptive analysis of data collected through self-administered surveys completed by clients and healthcare workers were completed. Clients starting ART at the study clinic, between January 2014 and December 2015, were included in the cohort analysis and followed up until December 2016. The survey data were collected from August to September 2017. The primary outcome for the cohort analysis was a comparison of loss to follow-up (LTFU) between clients staying in clinic care and those referred to adherence clubs. Survey data reported on client experiences of and healthcare worker perceptions of adherence club care. RESULTS: Cohort analysis reported on 465 participants, median baseline CD4 count 374 (IQR: 234 to 532) cells/µl and median follow-up time 20.7 (IQR 14.1 to 27.7) months. Overall, 202 (43.4%) participants were referred to an adherence club. LTFU was lower in those attending an adherence club (aHR =0.25, 95% CI: 0.11 to 0.56). This finding was confirmed on analysis restricted to those eligible for adherence club referral (aHR =0.28, 95% CI: 0.12 to 0.65). Factors highlighted as associated with successful adherence club implementation included: (i) referral of stable clients to the club, (ii) an ideal club size of ≥20 members, (iii) club services led by a counsellor (iv) using churches or community halls as venues (v) effective communication between all parties, and (vi) timely delivery of prepacked medication. CONCLUSIONS: This study showed good clinical outcomes, positive patient experiences and healthcare worker perceptions of the adherence club model. Factors associated with successful adherence club implementation, highlighted in this study, can be used to guide implementers in the scale-up of adherence club services across varied high-burden settings.

Attrition when providing antiretroviral treatment at CD4 counts >500cells/µL at three government clinics included in the HPTN 071 (PopART) trial in South Africa.

INTRODUCTION: WHO recommends antiretroviral treatment (ART) for all HIV-positive individuals. This study evaluated the association between baseline CD4 count and attrition in a cohort of HIV positive adults initiating ART at three department of health (DOH) clinics routinely providing ART at baseline CD4 counts >500cells/µL for the HPTN 071 (PopART) trial. METHODS: All clients attending the DOH clinics were managed according to standard care guidelines with the exception that those starting ART outside of pertinent local guidelines signed research informed consent. DOH data on all HIV-positive adult clients recorded as having initiated ART between January 2014 and November 2015 at the three study clinics was analysed. Attrition, included clients lost to follow up or died, and was defined as 'being three or more months late for an antiretroviral pharmacy pick-up appointment'. All clients were followed until attrition, transfer out or end May 2016. RESULTS: A total of 2423 clients with a median baseline CD4 count of 328 cells/µL (IQR 195-468) were included of whom 631 (26.0%) experienced attrition and 140 (5.8%) were TFO. Attrition was highest during the first six months of ART (IR 38.3/100 PY; 95% CI 34.8-42.1). Higher attrition was found amongst those with baseline CD4 counts > 500 cells/µL compared to those with baseline CD4 counts of 0-500 cells/µL (aHR 1.26, 95%CI 1.05 to 1.52) This finding was confirmed on subset analyses when restricted to individuals non-pregnant at baseline and when restricted to individuals with follow up of > 12months. CONCLUSIONS: Attrition in this study was high, particularly during the first six months of treatment. Attrition was highest amongst clients starting ART at baseline CD4 counts > 500 cells/µL. Strategies to improve retention amongst ART clients, particularly those starting ART at baseline CD4 counts >500cells/µL, need strengthening. Improved monitoring of clients moving in and out of ART care and between clinics will assist in better understanding attrition and ART coverage in high burden countries.

Incidence of Tuberculosis Among HIV-Positive Individuals Initiating Antiretroviral Treatment at Higher CD4 Counts in the HPTN 071 (PopART) Trial in South Africa.

INTRODUCTION: Antiretroviral treatment (ART) guidelines recommend life-long ART for all HIV-positive individuals. This study evaluated tuberculosis (TB) incidence on ART in a cohort of HIV-positive individuals starting ART regardless of CD4 count in a programmatic setting at 3 clinics included in the HPTN 071 (PopART) trial in South Africa. METHODS: A retrospective cohort analysis of HIV-positive individuals aged ≥18 years starting ART, between January 2014 and November 2015, was conducted. Follow-up was continued until 30 May 2016 or censored on the date of (1) incident TB, (2) loss to follow-up from HIV care or death, or (3) elective transfer out; whichever occurred first. RESULTS: The study included 2423 individuals. Median baseline CD4 count was 328 cells/µL (interquartile range 195-468); TB incidence rate was 4.41/100 person-years (95% confidence interval [CI]: 3.62 to 5.39). The adjusted hazard ratio of incident TB was 0.27 (95% CI: 0.12 to 0.62) when comparing individuals with baseline CD4 >500 and ≤500 cells/µL. Among individuals with baseline CD4 count >500 cells/µL, there were no incident TB cases in the first 3 months of follow-up. Adjusted hazard of incident TB was also higher among men (adjusted hazard ratio 2.16; 95% CI: 1.41 to 3.30). CONCLUSIONS: TB incidence after ART initiation was significantly lower among individuals starting ART at CD4 counts above 500 cells/µL. Scale-up of ART, regardless of CD4 count, has the potential to significantly reduce TB incidence among HIV-positive individuals. However, this needs to be combined with strengthening of other TB prevention strategies that target both HIV-positive and HIV-negative individuals.

Improving diabetic foot screening at a primary care clinic: A quality improvement project.

BACKGROUND: Foot screening is an important part of diabetic care as it prevents significant morbidity, loss of function and mortality from diabetic foot complications. However, foot screening is often neglected. AIM: This project was aimed at educating health care workers (HCWs) in a primary health care clinic to increase diabetic foot screening practices. SETTING: A primary health care clinic in the Western Cape province of South AfricaMethods: A quality improvement project was conducted. HCWs' needs were assessed using a questionnaire. This was followed by focus group discussions with the HCWs, which were recorded, transcribed and assessed using a general inductive approach. An intervention was designed based on common themes. Staff members were trained on foot screening and patient information pamphlets and screening tools were made available to all clinic staff. Thirty-two consecutive diabetic patient folders were audited to compare screening in 2013 with that in 2014 after initiation of the quality improvement cycle. RESULTS: HCWs' confidence in conducting foot screening using the diabetic foot assessment questionnaire improved markedly after training. Diabetic foot screening practices increased from 9% in 2013 to 69% in 2014 after the first quality improvement cycle. A strengths, opportunities, aspirations and results (SOAR) analysis showed promise for continuing quality improvement cycles. CONCLUSION: The findings showed a significant improvement in the number of diabetic patients screened. Using strategic planning with appreciative intent based on SOAR, proved to be motivational and can be used in the planning of the next cycle.

What keeps health professionals working in rural district hospitals in South Africa?

BACKGROUND: The theme of the 2014 Southern African Rural Health Conference was 'Building resilience in facing rural realities'. Retaining health professionals in South Africa is critical for sustainable health services. Only 12% of doctors and 19% of nurses have been retained in the rural areas. The aim of the workshop was to understand from health practitioners why they continued working in their rural settings. CONFERENCE WORKSHOP: The workshop consisted of 29 doctors, managers, academic family physicians, nurses and clinical associates from Southern Africa, with work experience from three weeks to 13 years, often in deep rural districts. Using the nominal group technique, the following question was explored, 'What is it that keeps you going to work every day?' Participants reflected on their work situation and listed and rated the important reasons for continuing to work. RESULTS: Five main themes emerged. A shared purpose, emanating from a deep sense of meaning, was the strongest reason for staying and working in a rural setting. Working in a team was second most important, with teamwork being related to attitudes and relationships, support from visiting specialists and opportunities to implement individual clinical skills. A culture of support was third, followed by opportunities for growth and continuing professional development, including teaching by outreaching specialists. The fifth theme was a healthy work-life balance. CONCLUSION: Health practitioners continue to work in rural settings for often deeper reasons relating to a sense of meaning, being part of a team that closely relate to each other and feeling supported.

Auditing chronic disease care: Does it make a difference?

BACKGROUND: An integrated audit tool was developed for five chronic diseases, namely diabetes, hypertension, asthma, chronic obstructive pulmonary disease and epilepsy. Annual audits have been done in the Western Cape Metro district since 2009. The year 2012 was the first year that all six districts in South Africa's Western Cape Province participated in the audit process. AIM: To determine whether clinical audits improve chronic disease care in health districts over time. SETTING: Western Cape Province, South Africa. METHODS: Internal audits were conducted of primary healthcare facility processes and equipment availability as well as a folder review of 10 folders per chronic condition per facility. Random systematic sampling was used to select the 10 folders for the folder review. Combined data for all facilities gave a provincial overview and allowed for comparison between districts. Analysis was done comparing districts that have been participating in the audit process from 2009 to 2010 ('2012 old') to districts that started auditing recently ('2012 new'). RESULTS: The number of facilities audited has steadily increased from 29 in 2009 to 129 in 2012. Improvements between different years have been modest, and the overall provincial average seemed worse in 2012 compared to 2011. However, there was an improvement in the '2012 old' districts compared to the '2012 new' districts for both the facility audit and the folder review, including for eight clinical indicators, with '2012 new' districts being less likely to record clinical processes (OR 0.25, 95% CI 0.21-0.31). CONCLUSION: These findings are an indication of the value of audits to improve care processes over the long term. It is hoped that this improvement will lead to improved patient outcomes.
