Impact of short message service and peer navigation on linkage to care and antiretroviral therapy initiation in South Africa.

OBJECTIVE: We examine the efficacy of short message service (SMS) and SMS with peer navigation (SMS + PN) in improving linkage to HIV care and initiation of antiretroviral therapy (ART). DESIGN: I-Care was a cluster randomized trial conducted in primary care facilities in North West Province, South Africa. The primary study outcome was retention in HIV care; this analysis includes secondary outcomes: linkage to care and ART initiation. METHODS: Eighteen primary care clinics were randomized to automated SMS ( n  = 7), automated and tailored SMS + PN ( n  = 7), or standard of care (SOC; n  = 4). Recently HIV diagnosed adults ( n  = 752) were recruited from October 2014 to April 2015. Those not previously linked to care ( n  = 352) contributed data to this analysis. Data extracted from clinical records were used to assess the days that elapsed between diagnosis and linkage to care and ART initiation. Cox proportional hazards models and generalized estimating equations were employed to compare outcomes between trial arms, overall and stratified by sex and pregnancy status. RESULTS: Overall, SMS ( n  = 132) and SMS + PN ( n  = 133) participants linked at 1.28 [95% confidence interval (CI): 1.01-1.61] and 1.60 (95% CI: 1.29-1.99) times the rate of SOC participants ( n  = 87), respectively. SMS + PN significantly improved time to ART initiation among non-pregnant women (hazards ratio: 1.68; 95% CI: 1.25-2.25) and men (hazards ratio: 1.83; 95% CI: 1.03-3.26) as compared with SOC. CONCLUSION: Results suggest SMS and peer navigation services significantly reduce time to linkage to HIV care in sub-Saharan Africa and that SMS + PN reduced time to ART initiation among men and non-pregnant women. Both should be considered candidates for integration into national programs. TRIAL REGISTRATION: NCT02417233, registered 12 December 2014; closed to accrual 17 April 2015.

Depressive symptoms and violence exposure in a population-based sample of adult women in South Africa.

Depressive symptoms are a major burden of disease globally and is associated with violence and poverty. However, much of the research linking these conditions is from resource-rich settings and among smaller, clinical samples. Secondary data from a household survey in Gauteng Province of South Africa examines the cross-sectional association between adult women's elevated depressive symptoms and markers of violence. Using tablet computers, participants self-completed interview modules to screen for depressive symptoms (Patient Health Questionnaire 2-item screener), childhood exposure to physical and sexual abuse (Childhood Trauma Questionnaire 4-item index), as well as past-year exposure to sexual or intimate partner violence (SIPV; WHO Multicountry Study instrument 4-item index). Socio-economic status, food security, education, and income were self-reported. Representative data at the ward level allows for modeling of results using survey commands and mixed-level modeling. Of the 7,276 adult women participating in the household survey, 42.1% reported elevated depressive symptoms. A total of 63.9% reported childhood violence exposure and 5.3% had past-year SIPV. Multi-level modeling suggests that violence is a strong predictor of depressive symptoms. Childhood abuse alone increases the odds of high depressive symptomology, after controlling for individual-level markers of poverty and neighborhood of residence (aOR 1.31, 95%, CI 1.17-1.37). Combined exposure to childhood abuse and past-year SIPV increased odds of reporting elevated depressive symptoms (aOR 2.05, 95%, CI 1.54-2.71). Ward characteristics account for 6% of the variance in depressive symptoms, over and above the contributions of household food security and socio-economic status. Exposure to violence in childhood and past-year SIPV were associated with depressive symptoms among women. These associations persist after controlling for socio-economic markers and latent neighborhood characteristics, which also had significant association with elevated depressive symptoms. These data suggest that efforts to reduce the burden of depressive symptoms may benefit from approaches that prevent violence against women and children.

Impact of SMS and peer navigation on retention in HIV care among adults in South Africa: results of a three-arm cluster randomized controlled trial.

INTRODUCTION: Few interventions have demonstrated improved retention in care for people living with HIV (PLHIV) in sub-Saharan Africa. We tested the efficacy of two personal support interventions - one using text messaging (SMS-only) and the second pairing SMS with peer navigation (SMS+PN) - to improve HIV care retention over one year. METHODS: In a cluster randomized control trial (NCT# 02417233) in North West Province, South Africa, we randomized 17 government clinics to three conditions: SMS-only (6), SMS+PN (7) or standard of care (SOC; 4). Participants at SMS-only clinics received appointment reminders, biweekly healthy living messages and twice monthly SMS check-ins. Participants at SMS+PN clinics received SMS appointment reminders and healthy living messages and spoke at least twice monthly with peer navigators (PLHIV receiving care) to address barriers to care. Outcomes were collected through biweekly clinical record extraction and surveys at baseline, six and 12 months. Retention in HIV care over one year was defined as clinic visits every three months for participants on antiretroviral therapy (ART) and CD4 screening every six months for pre-ART participants. We used generalized estimating equations, adjusting for clustering by clinic, to test for differences across conditions. RESULTS: Between October 2014 and April 2015, we enrolled 752 adult clients recently diagnosed with HIV (SOC: 167; SMS-only: 289; SMS+PN: 296). Individuals in the SMS+PN arm had approximately two more clinic visits over a year than those in other arms (p < 0.01) and were more likely to be retained in care over one year than those in SOC clinics (54% vs. 38%; OR: 1.77, CI: 1.02, 3.10). Differences between SMS+PN and SOC conditions remained significant when restricting analyses to the 628 participants on ART (61% vs. 45% retained; OR: 1.78, CI: 1.08, 2.93). The SMS-only intervention did not improve retention relative to SOC (40% vs. 38%, OR: 1.12, CI: 0.63, 1.98). CONCLUSIONS: A combination of SMS appointment reminders with personalized, peer-delivered support proved effective at enhancing retention in HIV care over one year. While some clients may only require appointment reminders, the SMS+PN approach offers increased flexibility and tailored, one-on-one support for patients struggling with more substantive challenges.

Household coverage, quality and costs of care provided by community health worker teams and the determining factors: findings from a mixed methods study in South Africa.

OBJECTIVE: Community health workers (CHWs) are undertaking more complex tasks as part of the move towards universal health coverage in South Africa. CHW programmes can improve access to care for vulnerable communities, but many such programmes struggle with insufficient supervision. In this paper, we assess coverage (proportion of households visited by a CHW in the past year and month), quality of care and costs of the service provided by CHW teams with differing configurations of supervisors, some based in formal clinics and some in community health posts. PARTICIPANTS: CHW, their supervisors, clinic staff, CHW clients. METHODS: We used mixed methods (a random household survey, focus group discussions, interviews and observations of the CHW at work) to examine the performance of six CHW teams in vulnerable communities in Sedibeng, South Africa. RESULTS: A CHW had visited 17% of households in the last year, and we estimated they were conducting one to two visits per day. At household registration visits, the CHW asked half of the questions required. Respondents remembered 20%-25% of the health messages that CHW delivered from a visit in the last month, and half of the respondents took the action recommended by the CHW. Training, supervision and motivation of the CHW, and collaboration with other clinic staff, were better with a senior nurse supervisor. We estimated that if CHW carried out four visits a day, coverage would increase to 30%-90% of households, suggesting that some teams need more CHW, as well as better supervision. CONCLUSION: Household coverage was low, and the service was limited. Support from the local facility was key to providing a quality service, and a senior supervisor facilitated this collaboration. Greater investment in numbers of CHW, supervisors, training and equipment is required for the potential benefits of the programme to be delivered.

Development of a tool for assessing quality of comprehensive care provided by community health workers in a community-based care programme in South Africa.

OBJECTIVE: To develop a tool for use by non-clinical fieldworkers for assessing the quality of care delivered by community health workers providing comprehensive care in households in low- and middle-income countries. DESIGN: We determined the content of the tool using multiple sources of information, including interactions with district managers, national training manuals and an exploratory study that included observations of 70 community health workers undertaking 518 household visits collected as part of a wider study. We also reviewed relevant literature, selecting relevant domains and quality markers. To refine the tool and manual we worked with the fieldworkers who had undertaken the observations. We constructed two scores summarising key aspects of care: (1) delivering messages and actions during household visit, and (2) communicating with the household; we also collected contextual data. The fieldworkers used the tool with community health workers in a different area to test feasibility. SETTING: South Africa, where community health workers have been brought into the public health system to address the shortage of healthcare workers and limited access to healthcare. It was embedded in an intervention study to improve quality of community health worker supervision. PRIMARY AND SECONDARY OUTCOMES: Our primary outcome was the completion of a tool and user manual. RESULTS: The tool consists of four sections, completed at different stages during community health worker household visits: before setting out, at entry to a household, during the household visit and after leaving the household. Following tool refinement, we found no problems on field-testing the tool. CONCLUSIONS: We have developed a tool for assessing quality of care delivered by community health workers at home visits, often an unobserved part of their role. The tool was developed for evaluating an intervention but could also be used to support training and management of community health workers.

Integrating community health workers into the formal health system to improve performance: a qualitative study on the role of on-site supervision in the South African programme.

OBJECTIVES: To explore the role of on-site supervision in community health worker (CHW) programmes and CHW integration into the health system. We compared the functioning of CHW teams reporting to a clinic-based nurse with teams supervised by a community-based nurse. We also consider whether a junior nurse can provide adequate supervision, given the shortage of senior nurses. DESIGN: A case study approach to study six CHW teams with different configurations of supervision and location. We used a range of qualitative methods: observation of CHW and their supervisors (126 days), focus group discussions (12) and interviews (117). SETTING: South Africa where a national CHW programme is being implemented with on-site supervision. PARTICIPANTS: CHWs, their supervisors, clinic managers and staff, district managers, key informants from the community and CHW clients. RESULTS: Effective supervisors supported CHWs through household visits, on-the-job training, debriefing, reviewing CHWs' daily logs and assistance with compiling reports. CHWs led by senior nurses were motivated and performed a greater range of tasks; junior nurses in these teams could better fulfil their role. Clinic-based teams with senior supervisors were better integrated and more able to ensure continuity of care. In contrast, teams with only junior supervisors, or based in the community, had less engagement with clinic staff, and were less able to ensure necessary care for patients, resulting in lower levels of trust from clients. CONCLUSION: Senior supervisors raised CHW skills, and successfully negotiated a place for CHWs in the health system. Collaboration with clinic staff reduced CHWs' marginalisation and increased motivation. Despite being clinic-based, teams without senior supervisors had lower skill levels and were less integrated into the health system.

Pre/post evaluation of a pilot prevention with positives training program for healthcare providers in North West Province, Republic of South Africa.

BACKGROUND: Prevention interventions for people living with HIV/AIDS are an important component of HIV programs. We report the results of a pilot evaluation of a four-hour, clinic-based training for healthcare providers in South Africa on HIV prevention assessments and messages. This pre/post pilot evaluation examined whether the training was associated with providers delivering more prevention messages. METHODS: Seventy providers were trained at four public primary care clinics with a high volume of HIV patients. Pre- and post-training patient exit surveys were conducted using Audio-Computer Assisted Structured Interviews. Seven provider appropriate messaging outcomes and one summary provider outcome were compared pre- and post-training using Poisson regression. RESULTS: Four hundred fifty-nine patients pre-training and 405 post-training with known HIV status were interviewed, including 175 and 176 HIV positive patients respectively. Among HIV positive patients, delivery of all appropriate messages by providers declined post-training. The summary outcome decreased from 56 to 50%; adjusted rate ratio 0.92 (95% CI = 0.87-0.97). Sensitivity analyses adjusting for training coverage and time since training detected fewer declines. Among HIV negative patients the summary score was stable at 32% pre- and post-training; adjusted rate ratio 1.05 (95% CI = 0.98-1.12). CONCLUSIONS: Surprisingly, this training was associated with a decrease in prevention messages delivered to HIV positive patients by providers. Limited training coverage and delays between training and post-training survey may partially account for this apparent decrease. A more targeted approach to prevention messages may be more effective.

Three methods of delivering clinic-based training on syndromic management of sexually transmitted diseases in South Africa: a pilot study.

INTRODUCTION: The South African National Department of Health sought to improve syndromic management of sexually transmitted infections (STIs). Continuing medical education on STIs was delivered at primary healthcare (PHC) clinics using one of three training methods: (1) lecture, (2) computer and (3) paper-based. Clinics with training were compared with control clinics. METHODS: Ten PHC clinics were randomly assigned to control and 10 to each training method arm. Clinicians participated in on-site training on six modules; two per week for three weeks. Each clinic was visited by three or four unannounced standardised patient (SP) actors pre-training and post-training. Male SPs reported symptoms of male urethritis syndrome and female SPs reported symptoms of vaginal discharge syndrome. Quality of healthcare was measured by whether or not clinicians completed five tasks: HIV test, genital exam, correct medications, condoms and partner notification. RESULTS: An average of 31% of clinicians from each PHC attended each module. Quality of STI care was low. Pre-training (n=128) clinicians completed an average of 1.63 tasks. Post-training (n=114) they completed 1.73. There was no change in the number of STI tasks completed in the control arm and an 11% increase overall in the training arms relative to the control (ratio of relative risk (RRR)=1.11, 95% CI 0.67 to 1.84). Across training arms, there was a 26% increase (RRR=1.26, 95% CI 0.77 to 2.06) associated with lecture, 17% increase (RRR=1.17, 95% CI 0.59 to 2.28) with paper-based and 13% decrease (RRR=0.87, 95% CI 0.40 to 1.90) with computer arm relative to the control. CONCLUSIONS: Future interventions should address increasing training attendance and computer-based training effectiveness. TRIAL REGISTRATION NUMBER: AEARCTR-0000668.

Infant feeding and school attainment in five cohorts from low- and middle-income countries.

BACKGROUND: Performance in intelligence tests tends to be higher among individuals breastfed as infants, but little is known about the association between breastfeeding and achieved schooling. We assessed the association of infant feeding with school achievement in five cohorts from low- and middle-income countries. Unlike high-income country settings where most previous studies come from, breastfeeding is not positively associated with socioeconomic position in our cohorts, thus reducing the likelihood of a spurious positive association. METHODOLOGY AND PRINCIPAL FINDINGS: Participants included 10,082 young adults from five birth cohorts (Brazil, India, Guatemala, the Philippines, and South Africa). The exposures variables were whether the subject was ever breastfed, total duration of breastfeeding, and age at introduction of complementary foods. We adjusted the estimates for age at follow up, sex, maternal age, smoking during pregnancy, birthweight and socioeconomic position at birth. The key outcome was the highest grade achieved at school. In unadjusted analyses, the association between ever breastfeeding and schooling was positive in Brazil, inverse in the Philippines, and null in South Africa; in adjusted analyses, these associations were attenuated. In Brazil, schooling was highest among individuals breastfed for 3-12 months whereas in the Philippines duration of breastfeeding was inversely associated with schooling; and null associations were observed in South Africa and Guatemala. These associations were attenuated in adjusted models. Late introduction of solid foods was associated with lower schooling achievement in Brazil and South Africa. CONCLUSION: Measures of breastfeeding are not consistently related to schooling achievement in contemporary cohorts of young adults in lower and middle-income countries.

Project Masihambisane: a cluster randomised controlled trial with peer mentors to improve outcomes for pregnant mothers living with HIV.

BACKGROUND: Pregnant women living with HIV (WLH) face daily challenges maintaining their own and their babies' health and mental health. Standard Prevention of Maternal to Child Transmission (PMTCT) programs are not designed to address these challenges. METHODS/DESIGN: As part of a cluster randomized controlled trial, WLH are invited to attend four antenatal and four postnatal small group sessions led by a peer WLH (a Peer Mentor). The WLH and their babies are assessed during pregnancy and at one week, six months, and twelve months post-birth. Mobile phones are used to collect routine information, complete questionnaires and remain in contact with participants over time. Pregnant WLH (N = 1200) are randomly assigned by clinic (N = 8 clinics) to an intervention program, called Masihambisane (n = 4 clinics, n = 600 WLH) or a standard care PMTCT control condition (n = 4 clinics; n = 600 WLH). DISCUSSION: Data collection with cellular phones are innovative and effective in low-resource settings. Standard PMTCT programs are not designed to address the daily challenges faced by WLH; Peer Mentors may be useful in supporting WLH to cope with these challenges.
