Accelerating caregivers' HIV status disclosure to community-based lay social welfare volunteers in Tanzania.

BACKGROUND: HIV status disclosure facilitates access to HIV-related prevention and treatment services and increases opportunities for social support, HIV risk reduction with partners, and index testing for sexual partners or children. This study assessed the effect of a program model of community-based social welfare volunteers on HIV status disclosure among caregivers of orphans and vulnerable children (OVC). METHODS: This was a longitudinal study, which was based on OVC caregivers who were beneficiaries of the USAID Kizazi Kipya project in Tanzania. They were enrolled (baseline) by community social welfare volunteers during 2017-2018, received services, and reassessed at midline in 2019. Caregivers who reported having been HIV tested, were asked to voluntarily report the status in order for the volunteers to establish and provide needed services. Those who reported their HIV status as negative or positive were grouped as "disclosed", and those who knew their status but did not report it were documented as "undisclosed". McNemar's tests compared disclosure rates at baseline and midline. Multivariable analysis was conducted using generalized estimating equation (GEE). RESULTS: The study analyzed 140,664 caregivers (72% female) from 81 district councils of Tanzania. Their mean age at enrollment was 47.4 years. Overall, 81.3% of the caregivers disclosed their HIV status to the project staff at baseline; this increased significantly to 96.1% at midline (p < 0.001). Disclosure at baseline varied significantly by sociodemographic characteristic (p < 0.05), with higher disclosure in females, among urban residents, and higher educated caregivers. However, the observed disclosure variations by sociodemographic characteristics at baseline disappeared at midline and disclosure reached around 96% across the characteristics (p > 0.05). In the multivariable analysis, caregivers' likelihood of HIV status disclosure was nearly 6 times higher at midline than at baseline, when baseline characteristics were adjusted for (OR = 5.76, 95% CI 5.59-5.94, p < 0.001). There were 26,329 caregivers who did not disclose their HIV status at baseline (i.e., 0% diclosure rate at baseline), but 94.7% (n = 24,933) had disclosed by midline, and their disclosure trend was rapidly increasing as their duration of exposure to the project increased. CONCLUSIONS: This study detected an increased caregivers' HIV status disclosure to the USAID Kizazi Kipya project staff by 14.8%, from 81.3% at baseline to 96.1% at midline within an average project exposure period of 1.4 years. The observed loss of sociodemographic differences in HIV status disclosure rate at midline implies that community-based interventions may be well-positioned to successfully address and eliminate sociodemographic barriers to service uptake and consequently improve services coverage and health outcomes.

Hunger and Adherence to Antiretroviral Therapy: Learning From HIV Positive Caregivers of Orphans and Vulnerable Children in Tanzania.

The association between hunger and adherence to antiretroviral therapy (ART) is less known especially in vulnerable populations receiving HIV care and treatment services. Caregivers of orphans and vulnerable children (OVC) are vulnerable and likely to experience hunger due to additional economic pressure in caring for OVC. Using data from the community-based, USAID-funded Kizazi Kipya project, this study assesses the association between hunger and ART adherence among caregivers of OVC in Tanzania. HIV positive caregivers enrolled in the project from January to July 2017 were analyzed. The outcome variable was adherence to ART, defined as "not having missed any ART dose in the last 30 days," and household hunger, measured using the Household Hunger Scale (HHS), was the main independent variable. Data analysis included multivariable logistic regression. The study analyzed 11,713 HIV positive caregivers who were on ART at the time of enrollment in the USAID Kizazi Kipya project in 2017. Aged 48.2 years on average, 72.9% of the caregivers were female. While 34.6% were in households with little to no hunger, 59.4 and 6.0% were in moderate hunger and severe hunger households, respectively. Overall, 90.0% of the caregivers did not miss any ART dose in the last 30 days. ART adherence rates declined as household hunger increased (p < 0.001). Multivariable analysis showed that the odds of adhering to ART was significantly lower by 42% among caregivers in moderate hunger households than those in little to no hunger households (OR = 0.58, 95% CI 0.50-0.68). The decline increased to 47% among those in severe hunger households (OR = 0.53, 95% CI 0.41-0.69). Hunger is an independent and a significant barrier to ART adherence among caregivers LHIV in Tanzania. Improving access to adequate food as part of HIV care and treatment services is likely to improve ART adherence in this population.

Programmatic determinants of successful referral to health and social services for orphans and vulnerable children: A longitudinal study in Tanzania.

BACKGROUND: Trained community workers (CWs) successfully deliver health and social services, especially due to greater community acceptance. Orphans and vulnerable children (OVC) and their caregivers (CG) often need support from several sectors. We identified CW, program and referral characteristics that were associated with success of referrals provided to OVC and their CG in Tanzania in a cross-sectoral bi-directional referral system. METHODS: Data for this secondary analysis come from the first two years (2017-2018) of the USAID funded Kizazi Kipya project. Referral success was defined as feedback and service received within 90 days post-referral provision. We analyzed factors that are associated with the referral success of HIV related, education, nutrition, parenting, household economic strengthening, and child protection services among OVC and CG, using generalized estimating equations. RESULTS: During the study period, 19,502 CWs in 68 councils provided 146,996 referrals to 132,640 beneficiaries. OVC had much lower referral success for HIV related services (48.1%) than CG (81.2%). Adjusted for other covariates, CW age (26-49 versus 18-25 years, for OVC aOR = 0.83, 95%CI (0.78, 0.87) and CW gender (males versus females, for OVC aOR = 1.12, 95%CI (1.08, 1.16); CG aOR = 0.84, 95%CI (0.78, 0.90)) were associated with referral success. CWs who had worked > 1 year in the project (aOR = 1.52, 95%CI 1.46, 1.58) and those with previous work experience as CW (aOR = 1.57, 95%CI (1.42, 1.74) more successfully referred OVC. Referrals provided to OVC for all other services were more successful compared to HIV referrals, with aORs ranging from 2.99 to 7.22. Longer project duration in the district council was associated with increased referral success for OVC (aOR = 1.16 per month 95%CI 1.15,1.17), but decreased for CG (aOR = 0.96, 95%CI 0.94, 0.97). Referral success was higher for OVC and CGs with multiple (versus single) referrals provided within the past 30 days (aOR = 1.28 95%CI 1.21, 1.36) and (aOR = 1.17, 95%CI (1.06, 1.30)) respectively. CONCLUSION: CW characteristics, referral type and project maturity had different and often contrasting associations with referral success for OVC versus for CG. These findings could help policymakers decide on the recruitment and allocation of CWs in community based multi-sectoral intervention programs to improve referral successes especially for OVC.

Relationship Between Food Insufficiency and HIV Infection Among Caregivers of Orphans and Vulnerable Children in Tanzania.

BACKGROUND: Although Tanzania experiences a general decline in HIV prevalence, some populations such as caregivers of orphans may be at a higher risk than the general population, suggesting that infection pathways still need further exploration. This study examines how food insufficiency relates to HIV infection among caregivers of orphans and vulnerable children (OVC) in Tanzania. DATA AND METHODS: Data are from a community-based, USAID-funded Kizazi Kipya project that aims at increasing the uptake of HIV services, as well as other health and social services by OVC and their caregivers in Tanzania. Caregivers who were enrolled in the project from January to July 2017 in seven regions of Tanzania, and had reported their HIV status to the project, were included in the analysis. While HIV status was the outcome, the main independent variable was food insufficiency which was assessed using the Household Hunger Scale (HHS). Using Stata (version 14.0; StataCorp LP, College Station, TX, USA), data analysis involved multilevel mixed-effects logistic regression.. RESULTS: Of the 47,617 caregivers analyzed (73.7% females), 61.8% and 4.6% were experiencing moderate and severe hunger, respectively. The overall HIV prevalence among the caregivers was 28.3%. Nevertheless, the prevalence was as high as 34.2% among caregivers in severe hunger households. Multivariate analysis revealed an increasing likelihood of being HIV positive as hunger increased (moderate hunger: OR=1.10, 95%CI: 1.03-1.18; severe hunger: OR=1.51, 95%CI: 1.32-1.74). These observations were adjusted for marital status, age, sex, education, place of residence, family size, disability status, and health insurance. CONCLUSION: Food insufficiency is associated with a higher likelihood of HIV infection among OVC caregivers in Tanzania, suggesting that improving access to adequate food has a potential to reduce HIV risks among them. Furthermore, food insufficiency could be considered an important criterion for targeting HIV testing and treatment services to expand coverage.

ART use and associated factors among HIV positive caregivers of orphans and vulnerable children in Tanzania.

BACKGROUND: Utilization of antiretroviral therapy (ART) is crucial for better health outcomes among people living with the human immunodeficiency virus (PLHIV). Nearly 30% of the 1.6 million PLHIV in Tanzania are not on treatment. Since HIV positive status is the only eligibility criterion for ART use, it is critical to understand the obstacles to ART access and uptake to reach universal coverage of ART among PLHIV. For the caregivers of orphans and vulnerable children (OVC) LHIV and not on ART, attempts to identify them and ensure that they initiate and continue using ART is critical for their wellbeing and their ability to care for their children. METHODS: Data are from the community-based, United States Agency for International Development (USAID)-funded Kizazi Kipya project that aims at scaling up the uptake of HIV/AIDS and other health and social services by orphans and vulnerable children (OVC) and their caregivers. HIV positive caregivers of OVC who were enrolled in the USAID Kizazi Kipya project between January 2017 and June 2018 were included in this cross-sectional study. The caregivers were drawn from 11 regions: Arusha, Iringa, Katavi, Kigoma, Mara, Mbeya, Morogoro, Ruvuma, Simiyu, Singida, and Tanga. The outcome variable was ART status (either using or not), which was enquired of each OVC caregiver LHIV at enrollment. Data analysis involved multivariable analysis using random-effects logistic regression to identify correlates of ART use. RESULTS: In total, 74,999 caregivers living with HIV with mean age of 44.4 years were analyzed. Of these, 96.4% were currently on ART at enrollment. In the multivariable analysis, ART use was 30% lower in urban than in rural areas (adjusted odds ratio (OR) = 0.70, 95% confidence interval (CI) 0.61-0.81). Food security improved the odds of being on ART (OR = 1.29, 95% CI 1.15-1.45). Disabled caregivers were 42% less likely than non-disabled ones to be on ART (OR = 0.58, 95% CI 0.45-0.76). Male caregivers with health insurance were 43% more likely than uninsured male caregivers to be on ART (OR = 1.43, 95% CI 1.11-1.83). Caregivers aged 40-49 years had 18% higher likelihood of being on ART than the youngest ones. Primary education level was associated with 26% increased odds of being on ART than no education (OR = 1.26, 95% CI 1.13-1.41). CONCLUSIONS: Although nearly all the caregivers LHIV in the current study were on ART (96.4%), more efforts are needed to achieve universal coverage. The unreached segments of the population LHIV, even if small, may lead to worse health outcomes, and also spur further spread of the HIV epidemic due to unachieved viral suppression. Targeting caregivers in urban areas, food insecure households, who are uninsured, and those with mental or physical disability can improve ART coverage among caregivers LHIV.

Correlates of Uptake of Antiretroviral Therapy in HIV-Positive Orphans and Vulnerable Children Aged 0-14 Years in Tanzania.

BACKGROUND: In 2018, only 65% of Tanzanian children aged 0-14 years living with human immunodeficiency virus (HIV) were on treatment, suggesting that challenges exist. This study explores factors associated with uptake of antiretroviral therapy (ART) among HIV-positive orphans and vulnerable children (OVC). METHODS: Data are from the USAID Kizazi Kipya project that aims to increase the uptake of HIV/AIDS and other health and social services by OVC and their caregivers. HIV-positive OVC aged 0-14 years who were enrolled in the project from January 2017 to September 2018 were analyzed. ART status (off ART or on ART) was the outcome variable. Multivariate analysis was performed using multilevel logistic regression. RESULTS: Of the 10,047 HIV-positive OVC aged 0-14 years analyzed, 93.5% were currently on ART at enrollment. In the multivariate analysis, OVC with male caregivers were 4-times more likely than those with female caregivers to be on ART (OR=4.03, 95% CI=1.49-10.90). OVC with HIV-positive caregivers were 12-times more likely than those with HIV-negative caregivers to be on ART (OR=12.0, 95% CI=3.81-37.70). OVC with caregivers who did not disclose their HIV status were 74% less likely to be on ART than OVC of HIV-negative caregivers (OR=0.26, 95% CI=0.08-0.90). OVC living in urban areas were more than 5-times as likely as their rural counterparts to be on ART (OR=5.55, 95% CI=2.21-14.0). CONCLUSION: The majority of the OVCLHIV in the current study were currently on ART (93.5%) at enrollment. However, uptake of ART by the OVC was dependent on factors external to themselves. Advancing ART uptake may require targeting OVC of female caregivers, OVC of HIV-negative caregivers, as well as OVC of caregivers of undisclosed HIV statu, and rural areas.

Determinants of undisclosed HIV status to a community-based HIV program: findings from caregivers of orphans and vulnerable children in Tanzania.

BACKGROUND: HIV status disclosure facilitates receipt of HIV prevention and treatment services. Although disclosure to sexual partners, family members or friends has been extensively studied, disclosure to community-based HIV programs is missing. This study assesses the magnitude of, and factors associated with undisclosed HIV status to a community-based HIV prevention program among caregivers of orphans and vulnerable children (OVC) in Tanzania. METHODS: Data are from the USAID-funded Kizazi Kipya project that seeks to increase uptake of HIV, health, and social services by OVC and their caregivers in Tanzania. Data on OVC caregivers who were enrolled in the project during January-March 2017 in 18 regions of Tanzania were analyzed. Caregivers included were those who had complete information on their HIV status disclosure, household socioeconomic status, and sociodemographic characteristics. HIV status was self-reported, with undisclosed status representing all those who knew their HIV status but did not disclose it. Multilevel mixed-effects logistic regression, with caregivers' HIV status disclosure being the outcome variable was conducted. RESULTS: The analysis was based on 59,683 OVC caregivers (mean age = 50.4 years), 71.2% of whom were female. Of these, 37.2% did not disclose their HIV status to the USAID Kizazi Kipya program at the time of enrollment. Multivariate analysis showed that the likelihood of HIV status non-disclosure was significantly higher among: male caregivers (odds ratio (OR) = 1.22, 95% confidence interval (CI) 1.16-1.28); unmarried (OR = 1.12, 95% CI 1.03-1.23); widowed (OR = 1.12, 95% CI 1.07-1.18); those without health insurance (OR = 1.36, 95% CI 1.28-1.45); age 61 + years (OR = 1.72, 95% CI 1.59-1.88); those with physical or mental disability (OR = 1.14, 95% CI 1.04-1.25); and rural residents (OR = 1.58, 95% CI 1.34-1.86). HIV status non-disclosure was less likely with higher education (p < 0.001); and with better economic status (p < 0.001). CONCLUSION: While improved education, economic strengthening support and expanding health insurance coverage appear to improve HIV status disclosure, greater attention may be required for men, unmarried, widowed, rural residents, and the elderly populations for their higher likelihood to conceal HIV status. This is a clear missed opportunity for timely care and treatment services for those that may be HIV positive. Further support is needed to support disclosure in this population.

Understanding the association between caregiver sex and HIV infection among orphans and vulnerable children in Tanzania: learning from the USAID Kizazi Kipya project.

BACKGROUND: Tanzania has met only 50.1% of the 90% target for diagnosing HIV in children. The country's pediatric case finding strategy uses global best practices of index testing, provider-initiated counselling and testing, and targeted community testing of at-risk populations to find about 50,000 children living with HIV (CLHIV) who are undiagnosed. However, context-specific strategies are necessary to find the hidden children to meet the full 90% target. This study assesses whether sex of the caregiver is associated with HIV status of orphans and vulnerable children (OVC) as a valuable strategy for enhanced pediatric case findings. METHODS: Data originate from the community-based, United States Agency for International Development (USAID)-funded Kizazi Kipya Project, which works towards increasing OVC's and their caregivers' uptake of HIV/AIDS and other health and social services in Tanzania. Included in this study are 39,578 OVC ages 0-19 years who the project enrolled during January through March 2017 in 18 regions of Tanzania and who voluntarily reported their HIV status. Data analysis involved multi-level logistic regression, with OVC HIV status as the outcome of interest and caregiver's sex as the main independent variable. RESULTS: Three-quarters (74.3%) of the OVC included in the study had female caregivers, and their overall HIV prevalence was 7.1%. The prevalence was significantly higher (p < 0.001) among OVC with male caregivers (7.8%) than among OVC with female caregivers (6.8%), and indeed, multivariate analysis showed that OVC with male caregivers were significantly 40% more likely to be HIV-positive than those with female caregivers (OR = 1.40, 95% CI 1.08-1.83). This effect was the strongest among 0-4 year-olds (OR = 4.02, 95% CI 1.61-10.03), declined to 1.72 among 5-9 year-olds (OR = 1.72, 95% CI 1.02-2.93), and lost significance for children over age 9 years. Other significant factors included OVC age and nutritional status; caregiver HIV status and marital status; household health insurance status, and family size; and rural versus urban residence. CONCLUSIONS: OVC in Tanzania with male caregivers have a 40% higher likelihood of being HIV-positive than those with female caregivers. HIV risk assessment activities should target OVC with male caregivers, as well as OVC who have malnutrition, HIV-positive caregivers, or caregivers who do not disclose their HIV status to community volunteers. Further, younger HIV-positive OVC are more likely to live in rural areas, while older HIV-positive OVC are more likely to live in urban areas. These factors should be integrated in HIV risk assessment algorithms to enhance HIV testing yields and pediatric case-finding in the OVC population in Tanzania.

Success of a South-South collaboration on Human Resources Information Systems (HRIS) in health: a case of Kenya and Zambia HRIS collaboration.

BACKGROUND: Shortage of health workforce in most African countries is a major impediment to achieving health and development goals. Countries are encouraged to develop evidence-based strategies to scale up their health workforce in order to bridge the gap. South-South collaborations have gained popularity due to similarities in the challenges faced in the region. This strategy has been used in trade, education, and health sector among others. This paper is a road map of using a South-South collaboration to develop a Human Resources Information System (HRIS) to inform scale-up of the health workforce. CASE PRESENTATION: In the last decade, Kenya implemented one of the most comprehensive HRIS in Africa. The HRIS was funded by the US President's Emergency Plan for AIDS Relief (PEPFAR) through the Centers for Disease Control and Prevention (CDC) and implemented by Emory University. The Kenyan team collaborated with the Zambian team to establish a similar HRIS in Zambia. This case study describes the collaboration activities between Zambia and Kenya which included needs assessment, establishment of project office, stakeholders' sensitization, technical assistance and knowledge transfer, software reuse, documents and guidelines reuse, project structure and management, and project formative evaluation. Furthermore, it highlights the need for adopting effective communication strategies, collaborative planning, teamwork, willingness to learn, and having minimum technical skills from the recipient country as lessons learned from the collaboration. As a result of the collaboration, while Kenya took 5 years, Zambia was able to implement the project within 2 years which is less than half the time it took Kenya. CONCLUSIONS: This case presents a unique experience in the use of South-South collaboration in establishing a HRIS. It illustrates the steps and resources needed while identifying the successes and challenges in undertaking such collaboration.

Posttraumatic stress symptoms and structure among orphan and vulnerable children and adolescents in Zambia.

BACKGROUND: Scant information exists on posttraumatic stress disorder (PTSD) symptoms and structure in youth from developing countries. METHODS: We describe the symptom profile and exposure to trauma experiences among 343 orphan and vulnerable children and adolescents from Zambia. We distinguished profiles of posttraumatic stress symptoms using latent class analysis. RESULTS: Average number of trauma-related symptoms (21.6; range 0-38) was similar across sex and age. Latent class model suggested three classes varying by level of severity: low (31% of the sample), medium (45% of the sample), and high (24% of the sample) symptomatology. CONCLUSIONS: Results suggest that PTSD is a continuously distributed latent trait.

An evaluation of trauma focused cognitive behavioral therapy for children in Zambia.

To monitor and evaluate the feasibility of implementing Trauma Focused-Cognitive Behavioral Therapy (TF-CBT) to address trauma and stress-related symptoms in orphans and vulnerable children (OVC) in Zambia as part of ongoing programming within a non-governmental organization (NGO). As part of ongoing programming, voluntary care-workers administered locally validated assessments to identify children who met criteria for moderate to severe trauma symptomatology. Local lay counselors implemented TF-CBT with identified families, while participating in ongoing supervision. Fifty-eight children and adolescents aged 5-18 completed the TF-CBT treatment, with pre- and post-assessments. The mean number of traumas reported by the treatment completers (N=58) was 4.11. Post assessments showed significant reductions in severity of trauma symptoms (p<0.0001), and severity of shame symptoms (p<0.0001). Our results suggest that TF-CBT is a feasible treatment option in Zambia for OVC. A decrease in symptoms suggests that a controlled trial is warranted. Implementation factors monitored suggest that it is feasible to integrate and evaluate evidence-based mental health assessments and intervention into programmatic services run by an NGO in low/middle resource countries. Results also support the effectiveness of implementation strategies such as task shifting, and the Apprenticeship Model of training and supervision.
