Non-Uptake of HIV Testing in Children at Risk in Two Urban and Rural Settings in Zambia: A Mixed-Methods Study.

ABSTRACT: This article investigates reasons why children who were considered at risk of HIV were not taken for HIV testing by their caregivers. Qualitative and quantitative data collected in Zambia from 2010-11 revealed that twelve percent of caregivers who stated that they had been suspecting an HIV infection in a child in their custody had not had the child tested. Fears of negative reactions from the family were the most often stated reason for not testing a child. Experience of pre-existing conflicts between the couple or within the family (aOR 1.35, 95% CI 1.00-1.82) and observed stigmatisation of seropositive children in one's own neighbourhood (aOR 1.69, 95% CI1.20-2.39) showed significant associations for not testing a child perceived at risk of HIV. Although services for HIV testing and treatment of children have been made available through national policies and programmes, some women and children were denied access leading to delayed diagnosis and treatment-not on the side of the health system, but on the household level. Social norms, such as assigning the male household head the power to decide over the use of healthcare services by his wife and children, jeopardize women's bargaining power to claim their rights to healthcare, especially in a conflict-affected relationship. Social norms and customary and statutory regulations that disadvantage women and their children must be addressed at every level-including the community and household-in order to effectively decrease barriers to HIV related care.

Project description:This study aimed to explore factors shaping the decision to undergo Human Immunodeficiency Virus (HIV) testing among men in rural Burkina Faso.The study took place in 2009 in the Nouna Health District and adopted a triangulation mixed methods design. The quantitative component relied on data collected through a structured survey on a representative sample of 1130 households. The qualitative component relied on 38 in-depth interviews, with men purposely selected to represent variation in testing decision, age, and place of residence. A two-part model was conducted, with two distinct outcome variables, i.e. "being offered an HIV test" and "having done an HIV test". The qualitative data analysis relied on inductive coding conducted by three independent analysts.Of the 937 men, 357 had been offered an HIV test and 97 had taken the test. Younger age, household wealth, living in a village under demographic surveillance, and knowing that HIV testing is available at primary health facilities were all positively associated with the probability of being offered an HIV test. Household wealth and literacy were found to be positively associated, and distance was found to be negatively associated with the probability of having taken an HIV test. Qualitative findings indicated that the limited uptake of HIV testing was linked to poor knowledge on service availability and to low risk perceptions.With only 10% of the total sample ever having tested for HIV, our study confirmed that male HIV testing remains unacceptably low in Sub-Saharan Africa. This results from a combination of health system factors, indicating general barriers to access, and motivational factors, such as one's own knowledge of service availability and risk perceptions. Our findings suggested that using antenatal care and curative services as the exclusive entry points into HIV testing may not be sufficient to reach large portions of the male population. Thus, additional strategies are urgently needed to increase service uptake.

Project description:BACKGROUND:Knowledge of HIV status remains below target in sub-Saharan Africa, especially among men and adolescents. HIV self-testing (HIVST) is a novel approach that enables unique distribution strategies, with potential to be highly decentralised and to provide complementary coverage to facility-based testing approaches. However, substantial gaps in evidence remain on the effectiveness and cost-effectiveness of HIVST, particularly in rural settings, and on approaches to facilitate linkage to confirmatory HIV testing, prevention, and treatment services. This protocol describes two cluster-randomized trials (CRT) included within the UNITAID/PSI HIV Self-Testing Africa (STAR) project. METHODS:Two independent CRTs were designed around existing reproductive health programmes in rural Malawi and rural/peri-urban Zambia. Common features include use of constrained randomisation to allocate health clinic catchment areas to either standard HIV testing (SOC) or SOC plus community-based distribution of OraQuick HIV Self Tests (Bethlehem, PA USA, assembled in Thailand) by trained lay distributors selected by the community. Community-based distribution agents will be trained (3-day curriculum) to provide brief demonstration of kit use and interpretation, information and encouragement to access follow up services, and management of social harm. The primary outcome of both CRTs is the proportion of the population aged 16 years and older who tested for HIV within the 12-month intervention period. Secondary outcomes in both trials include lifetime HIV testing, antiretroviral therapy (ART) initiation and ART use. Circumcision status among males will be a secondary outcome in Zambia and clinic-level demand for ART will be a secondary outcome in Malawi. Outcomes will be measured using cross-sectional household surveys, and routine data extraction from participating clinics. Costing studies will be used to evaluate the cost-effectiveness of the intervention arm. Qualitative research will be used to guide distribution and explore reasons for testing and linkage to onward care. DISCUSSION:The STAR-Malawi and STAR-Zambia trials will provide rigorous evidence of whether community-based lay HIVST distribution is an effective and cost-effective approach to increasing coverage of HIV testing and demand for follow-on HIV services in rural and peri-urban communities in sub-Saharan Africa.

Project description:Improved primary health care is needed in developing countries to effectively manage the growing burden of hypertension. Our objective was to evaluate hypertension management in Zambian rural primary care clinics using process and outcome indicators to assess the screening, monitoring, treatment and control of high blood pressure.Better Health Outcomes through Mentoring and Assessment (BHOMA) is a 5-year, randomized stepped-wedge trial of improved clinical service delivery underway in 46 rural Zambian clinics. Clinical data were collected as part of routine patient care from an electronic medical record system, and reviewed for site performance over time according to hypertension related indicators: screening (blood pressure measurement), management (recorded diagnosis, physical exam or urinalysis), treatment (on medication), and control. Quantitative data was used to develop guides for qualitative in-depth interviews, conducted with health care providers at a proportional sample of half (20) of clinics. Qualitative data was iteratively analyzed for thematic content.From January 2011 to December 2014, 318,380 visits to 46 primary care clinics by adults aged???25 years with blood pressure measurements were included. Blood pressure measurement at vital sign screening was initially high at 89.1% overall (range: 70.1-100%), but decreased to 62.1% (range: 0-100%) by 48 months after intervention start. The majority of hypertensive patients made only one visit to the clinics (57.8%). Out of 9022 patients with at least two visits with an elevated blood pressure, only 49.3% had a chart recorded hypertension diagnosis. Process indicators for monitoring hypertension were <10% and did not improve with time. In in-depth interviews, antihypertensive medication shortages were common, with 15/20 clinics reporting hydrochlorothiazide-amiloride stockouts. Principal challenges in hypertension management included 1) equipment and personnel shortages, 2) provider belief that multiple visits were needed before official management, 3) medication stock-outs, leading to improper prescriptions and 4) poor patient visit attendance.Our findings suggest that numerous barriers stand in the way of hypertension diagnosis and management in Zambian primary health facilities. Future work should focus on performance indicator development and validation in low resource contexts, to facilitate regular and systematic data review to improve patient outcomes.ClinicalTrials.gov, Identifier NCT01942278 .

Project description:OBJECTIVES:The aim of this study was to estimate the frequency of disclosure to and testing of contacts of patients with hepatitis B virus (HBV) in Zambia. DESIGN:We used a convergent parallel mixed-method research design including a quantitative survey and focus group discussions with patients with HBV. SETTING:A university hospital in Lusaka, Zambia. PARTICIPANTS:79 hepatitis B surface antigen (HBsAg)-positive, HIV-negative, adults (18+ years) receiving HBV care completed a quantitative survey and 32 also participated in a focus group discussion. OUTCOMES AND ANALYSIS:Contacts of patients with HBV were enumerated and patient-reported disclosure, contact testing and contact HBV test results were used to develop a testing cascade. Using multivariable logistic regression, we identified factors associated with disclosure of HBV status. In focus groups, we explored how index patient knowledge and awareness of their condition shaped perspectives on contact disclosure and testing. Focus groups coding and analysis followed a thematic analysis approach. RESULTS:Among 79 patients with HBV (median age 35 years; 26.6% women), the majority reported disclosure to ?1 contact. According to the index patients' knowledge, of 776 contacts enumerated, 326 (42.1%) were disclosed to, 77 (9.9%) were tested, 67 (8.6%) received results and 8 (11.9%) were HBsAg-positive. Increased stigma score was associated with reduced disclosure. In focus groups, HBV awareness, knowledge and stigma emerged as barriers to disclosure and referral of contacts for testing. Association of HBV with HIV-related stigma was also reported as a strong barrier to contact disclosure and testing and to taking antivirals for HBV monoinfection. CONCLUSIONS:HBV contact disclosure and testing were feasible and yielded new diagnoses in Zambia. A better understanding of barriers to seeking HBV testing and treatment is needed to scale-up this important intervention in Africa. TRIALS REGISTRATION NUMBER:NCT03158818.

Project description:BackgroundEarly infant diagnosis is important for timely identification of HIV-infected infants and linkage to care. Testing at birth has been implemented to facilitate earlier diagnosis of HIV infection but may present new challenges. This study was conducted to understand the acceptability and feasibility of birth testing in urban and rural settings in southern Zambia.MethodsThis cross-sectional study was conducted at 11 hospitals and clinics in Livingstone, Choma, and Macha in Southern Province, Zambia from 2016 to 2018. Infants born to pregnant women living with HIV at the sites were eligible for enrollment. After enrollment, a questionnaire was administered to the mother and a dried blood spot card was collected from infants for testing at a central laboratory. When results were available, mothers were notified to return to the clinic. Acceptability of birth testing was evaluated based on the proportion of women who agreed to participate and the reasons for non-participation among women who declined. Feasibility of testing at birth was evaluated using turnaround times for returning results, the proportion of women receiving results, and linkage to care for infants testing positive.ResultsOne thousand four hundred three women were approached for the study. A small proportion declined due to refusal of birth testing (0 to 8.2% across sites). One thousand two hundred ninety women agreed to have their infants tested. The proportion of mothers receiving results ranged from 51.6 to 92.1%, and was significantly lower at the hospital than clinics in Livingstone (51.6% vs. 69.8%; p < 0.0001) and Macha (69.5% vs. 85.7%; p < 0.0001) but not Choma (85.7% vs. 92.1%; p = 0.34). For mothers who received test results, the median turnaround time from sample collection was 67 days in Livingstone and 53 days in Macha and Choma. Overall, 23 (1.8%) infants tested positive for HIV but only 8 (34.8%) were linked to care a median of 68 days (range: 29, 784) after sample collection.ConclusionsWhile testing at birth was acceptable, this study highlights the operational challenges under a centralized laboratory testing system. Point-of-care platforms are needed for rapid testing and return of results so HIV-infected children can be identified, linked to care, and treated as early as possible.

Project description:BackgroundThe prevalence of sexually transmitted infections (STIs) among youth is high in sub-Saharan Africa. We investigated the uptake of testing for and prevalence of Chlamydia trachomatis (chlamydia) and Neisseria gonorrhoeae (gonorrhoea) infections among youth in community-based settings in Zimbabwe, and explored the facilitators and barriers to testing.MethodsThis study was nested within a cluster randomised trial of community-based delivery of integrated HIV and sexual and reproductive health services for youth aged 16-24 years. Chlamydia and gonorrhoea testing via urine samples using the Xpert CT/NG test was offered in the four intervention clusters in Harare, Zimbabwe. Factors associated with testing uptake were investigated in a subset of participants (n=257) using hierarchical multivariate logistic regression. In-depth interviews with a separate purposively selected sample (n=26) explored facilitators and barriers to STI testing and partner notification and were analysed using thematic analysis.FindingsBetween June 1, 2019, and Jan 31, 2020, there were 6200 attendances by 4440 participants (78·2% women, 21·8% men) median age 20·3 (IQR 17·9-22·8) years. 1478 participants had 1501 tests done, and 248 tests were positive and 1253 tests were negative for chlamydia or gonorrhoea, or both. STI test uptake was 33·3% (95% CI 31·9-34·7), increasing from 11·7% in June, 2019, to 37·1% in January, 2020. The prevalence of chlamydia or gonorrhoea, or both, was 16·5% (95% CI 14·7-18·5; 248 of 1501), with only seven participants (3%) showing symptoms. The overall yield of testing was 4·0% (95% CI 3·5-4·5; 248 of 6200). Uptake was associated with having symptoms (adjusted odds ratio [OR] 14·8, 95% CI 1·66-132·07) and negatively associated with being single (adjusted OR 0·33, 95% CI 0·13-0·84) or having a boyfriend or girlfriend (adjusted OR 0·19, 95% CI 0·087-0·43) compared with being married, and being a student compared with being employed (adjusted OR 0·26, 95% CI 0·10-0·68). Perceived risk and symptoms of STIs were motivators for testing whereas misinformation, anticipated stigma, and concern about confidentiality were barriers.InterpretationThe prevalence of chlamydia or gonorrhoea, or both, was high among youth but only a minority were symptomatic. Therefore most infections would remain untreated without access to STI testing. Provision of education, counselling, and confidentiality are essential to improve uptake and acceptability of STI testing.FundingWellcome Trust.
