Voluntary Counseling and Testing, Antiretroviral Therapy Access, and HIV-Related Stigma: Global Progress and Challenges. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19116597. [PMID: 35682181 PMCID: PMC9179955 DOI: 10.3390/ijerph19116597] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 05/23/2022] [Accepted: 05/25/2022] [Indexed: 02/04/2023]
Abstract
To date, about 37 million people are living with the human immunodeficiency virus (HIV) and an estimated 680,000 people have died from acquired immune deficiency syndrome (AIDS) related illnesses globally. While all countries have been impacted by HIV, some have been significantly more impacted than others, particularly countries in sub-Saharan Africa. The purpose of this paper was to identify progress made in HIV prevention globally, particularly in the areas of voluntary counseling and testing (VCT) uptake, access to antiretroviral therapy (ART), and HIV-related stigma. With the development of ART, a cocktail of medications for the treatment of HIV, VCT uptake increased, as it became apparent that the medication would only be prescribed after an HIV diagnosis through testing. Widely considered a critical gateway to HIV prevention and treatment, VCT is being implemented in many countries, and as a result, about 38 million people living with HIV in 2018 had access to ART. Regardless of this success, major challenges still remain. We did an electronic search of 135 articles in English related to global HIV progress and challenges indexed in PubMed, ResearchGate, Google, and other search engines from 1998 to 2021. Sixty articles met the inclusion criteria for this paper. Data on trends in ART coverage were obtained from the Joint United Nations Programme on HIV/AIDS (UNAIDS) website. These data were used to show ART coverage globally in World Health Organization (WHO) regions. It was found that while global successes have been chalked in the areas of VCT uptake and ART coverage, HIV-related stigma has impeded greater success. This paper summarizes and discusses global successes and challenges in HIV prevention efforts in the past four decades with a focus on VCT, ART, and HIV-related stigma.

Correlates of loss to follow-up and missed diagnosis among HIV-exposed infants throughout the breastfeeding period in southern Mozambique. PLoS One 2020; 15:e0237993. [PMID: 32822388 PMCID: PMC7444585 DOI: 10.1371/journal.pone.0237993] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2020] [Accepted: 08/06/2020] [Indexed: 12/02/2022] Open
Abstract
Introduction Complete follow-up of human immunodeficiency virus (HIV)-exposed infants (HEI) is crucial for a successful prevention of mother-to-child HIV transmission. This study analyzed the HEI follow-up and factors associated with loss to follow-up (LTFU) in southern Mozambique. Methods This retrospective cohort study used the data of HEI enrolled between June 2017 and June 2018, followed-up for 18 months. The outcomes were the proportion of infants with completed follow-up and a definitive diagnosis, and the presence of clinical events. Kaplan–Meier survival analysis was used to calculate the cumulative probability of LTFU and of clinical events. Factors associated with LTFU and clinical events were analyzed using Cox regression to calculate the hazard ratio (HR) and adjusted HR (AHR), with a 95% confidence interval (CI) and a significance cutoff of p<0.05. Results 1413 infants were enrolled (49% males) at a median age of 32 days (IQR 31–41); the median follow-up time was 12 months (IQR 8.2–14.2); 1129 (80%) completed follow-up and had a definitive diagnosis, 58 (4%) were HIV-positive, 225 (16%) were LTFU; 266 (19%) presented a clinical event. Factors associated with LTFU were: age >2 months at entry (AHR, 1.58; 95% CI, 1.12–2.23), non-exclusive breastfeeding (AHR, 1.44; 95% CI, 1.01–2.06), poor cotrimoxazole adherence (AHR, 3.42; 95% CI, 1.59–7.35), and clinical events (AHR, 0.51; 95% CI, 0.34–0.77). Factors associated with clinical events were: malnutrition (AHR, 10.06; 95% CI, 5.92–17.09), non-exclusive breastfeeding (AHR, 1.98; 95% CI, 1.34–2.93), no nevirapine prophylaxis (AHR, 1.67; 95% CI, 1.18–2.36), and poor cotrimoxazole adherence (AHR, 2.62; 95% CI, 1.10–6.22). Conclusion The high rate of HEI LTFU, associated with delayed linkage to postnatal care, poor prophylaxis adherence, non-exclusive breastfeeding, indicates the need to design a differentiated service delivery model that is tailored to the mothers’ and infants’ specific needs.

Abstract
Background People living with HIV treated with antiretroviral therapy (ART) are now living longer and thus many are requiring surgical procedures. For healthcare resource planning, it would be helpful to better understand the prevalence of HIV in surgical patients, the types of surgery HIV-positive patients are undergoing and whether HIV status impacts mortality. Objective The goal of this study was to determine the prevalence of HIV in surgical inpatients and the extent of ART coverage, as well as to assess any differences between HIV-positive and HIV-negative patients in type of surgery undergone and in-hospital mortality at Karanda Mission Hospital, Mount Darwin, Zimbabwe. Method A 1-year retrospective chart review was undertaken to collect clinical and demographic data for adult (excluding maternity cases) and paediatric surgical inpatients including age, sex, type of surgery, HIV status, CD4+ counts and, if patient was HIV-positive, whether he or she was taking ART. Results and conclusion: Charts for 1510 surgical inpatient stays were reviewed. HIV prevalence among the adults was higher than that in the general population in Zimbabwe in 2016 (23.2% vs. 14.7%). There was no significant difference in inpatient mortality between the HIV-negative group and the HIV-positive group. Within the group of patients with malignancies, people living with HIV were significantly younger than uninfected patients (mean age 50.5 vs. 64.4 years; p < 0.01). There were correlations between HIV and certain malignancies. Thus, in addition to AIDS-defining illnesses, clinicians must be alert to squamous cell carcinoma and oesophageal, anal and penile cancers in HIV-positive patients.

Front Public Health 2018; 6:139. [PMID: 29868546 PMCID: PMC5962700 DOI: 10.3389/fpubh.2018.00139] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Accepted: 04/23/2018] [Indexed: 12/02/2022] Open
Abstract
Introduction: Early infant diagnosis (EID) of Human Immunodeficiency Virus (HIV) provides an opportunity for follow up of HIV exposed children for early detection of infection and timely access to antiretroviral treatment. We assessed predictors for accessing HIV diagnostic services among under-five children exposed to HIV infection in Muheza district, Tanzania. Methods: A cross sectional facility-based study among mother/guardian-child pairs of HIV exposed children was conducted from June 2015 to June 2016. Using a structured questionnaire, we collected information on HIV status, socio-demographic characteristics and other relevant data. Multiple regression analyses were used to investigate associations of potential predictors of accessing EID services. Results: A total of 576 children with their respective mothers/guardians were recruited. Of the 576 mothers/guardians, 549 (95.3%) were the biological mothers with a median age of 34 years (inter-quartile range: 30–38 years). The median age of the 576 children was 15 months (inter- quartile range: 8.5–38.0 months). A total of 251 (43.6%) children were born to mothers with unknown HIV status at conception. Only 329 (57.1%) children accessed EID between 4 and 6 weeks of age. Children born to mothers with unknown HIV status at conception (AOR = 0.6, 95% CI 0.4–0.8) and those with ages 13–59 months (AOR = 0.4, 95% CI 0.2–0.6) were the significant predictors of missed opportunity to access EID. Children living with the head of household with at least a high education level had higher chances of accessing EID (AOR = 1.8, 95% CI 1.1–3.3). Their chances of accessing EID services was three-fold higher among mothers/guardians with good knowledge of HIV infection prevention of mother to child transmission (AOR = 3.2, 95% CI 2.0–5.2) than those with poor knowledge. Mothers/guardians living in rural areas had poorer knowledge of HIV infection prevention of mother to child transmission (AOR = 0.6, 95% CI 0.4–0.9) than those living in urban areas. Conclusion: Accessibility of EID services among children below 5 years exposed to HIV infection in Muheza is low. These findings stress the need for continued HIV education and outreach services, particularly in rural areas in order to improve maternal and child health.

Abstract
Through various campaigns and strategies, more women are being tested for HIV in countries with a high prevalence of the virus. Despite the ready availability of treatment at government clinics in sub-Saharan African countries like Swaziland, women consistently report difficulty in maintaining access to treatment. Drawing on two individual case studies selected from a larger study of the so-called leaky cascade in Swaziland, we illustrate the protracted journeys married women undertake to initiate treatment. We demonstrate how women manoeuvre tactically after diagnosis, highlight factors that influence their decisions related to initiating treatment, and detail the actors involved in the decision-making process. Our research shows the persistence of structural factors that inhibit access, including economic constraints, gender inequality and patriarchal social norms. Patients referred as ‘lost to follow up’ are in many cases actively pursuing treatment within a context that includes the biomedical health system, but also extends well beyond it. We argue that the phrase ‘lost to follow up’ conceals the complex social navigation required by women to initiate and maintain access to treatment. Further, we suggest that many of the logistical challenges of monitoring and tracking people with HIV can be better addressed by taking into account the structural and social aspects of delayed treatment initiative.

Abstract
BACKGROUND/OBJECTIVES In the last decade, many strategies have called for integration of HIV and child survival platforms to reduce missed opportunities and improve child health outcomes. Countries with generalized HIV epidemics have been encouraged to optimize each clinical encounter to bend the HIV epidemic curve. This systematic review looks at integrated child health services and summarizes evidence on their health outcomes, service uptake, acceptability, and identified enablers and barriers. METHODS Databases were systematically searched for peer-reviewed studies. Interventions of interest were HIV services integrated with: neonatal/child services for children <5 years, hospital care of children <5 years, immunizations, and nutrition services. Outcomes of interest were: health outcomes of children <5 years, integrated services uptake, acceptability, and enablers and barriers. PROSPERO ID: CRD42017082444. RESULTS Twenty-eight articles were reviewed: 25 (89%) evaluated the integration of HIV services into child health platforms, while three articles (11%) investigated the integration of child health services into HIV platforms. Studies measured health outcomes of children (n=9); service uptake (n=18); acceptability of integrated services (n=8), and enablers and barriers to service integration (n=14). Service integration had positive effects on child health outcomes, HIV testing, and postnatal service uptake. Integrated services were generally acceptable, although confidentiality and stigma were concerns. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS Each clinical "touch point" with infants and children is an opportunity to provide comprehensive health services. In the current era of flat funding levels, integration of HIV and child health services is an effective, acceptable way to achieve positive child health outcomes.

Abstract
PURPOSE OF REVIEW It is 20 years since the start of the combination antiretroviral therapy (cART) era and more than 10 years since cART scale-up began in resource-limited settings. We examined survival of vertically HIV-infected infants and children in the cART era. RECENT FINDINGS Good survival has been achieved on cART in all settings with up to 10-fold mortality reductions compared with before cART availability. Although mortality risk remains high in the first few months after cART initiation in young children with severe disease, it drops rapidly thereafter even for those who started with advanced disease, and longer term mortality risk is low. However, suboptimal retention on cART in routine programs threatens good survival outcomes and even on treatment children continue to experience high comorbidity risk; infections remain the major cause of death. Interventions to address infection risk include a cotrimoxazole prophylaxis, isoniazid preventive therapy, routine childhood and influenza immunization, and improving maternal survival. SUMMARY Pediatric survival has improved substantially with cART and HIV-infected children are aging into adulthood. It is important to ensure access to diagnosis and early cART, good program retention as well as optimal comorbidity prophylaxis and treatment to achieve the best possible long-term survival and health outcomes for vertically infected children.

East Afr Health Res J 2017; 1:123-129. [PMID: 34308166 PMCID: PMC8279252 DOI: 10.24248/eahrj-d-16-00359] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2016] [Accepted: 07/13/2017] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND There is low utilisation of provider-initiated HIV testing and counselling (PITC) services for infants and children under 5 years old in many low- and middle-income countries including Tanzania. Studies have shown that various factors contribute to low use of PITC, includes the unavailability of the polymerase chain reaction (PCR) test and other specialised techniques for testing children less than 18 months old as well as the reluctance of some parents and caregivers to undertake HIV testing for their children because of the fear of stigma associated with HIV/AIDS. This study explored health system barriers at the district and community levels affecting the provision of PITC for infants and children under 5 in Tanzania using a case study of 2 districts. METHODS A qualitative study was conducted in 1 urban and 1 rural district in the southern part of Tanzania. In-depth interviews, focus group discussions, and a desk review of documents were used to obtain the information. Respondents were purposively enrolled in the study and thematic analysis was used to generate findings. RESULTS Provision of PITC services faces a number of district-level health system barriers, including lack of adequate health staff in health facilities both in number and skills, lack of adequate infrastructure, and erratic shortage of supplies. At the community level, community members' low understanding about the importance of PITC services as well as existing stigma associated with HIV/AIDS have constrained the provision of PITC services. CONCLUSION This study concludes that for effective implementation of PITC, the health system should strengthen health facilities through training of service providers on PITC, deploying adequately skilled health workers, supplying sufficient medicines and other supplies, and promoting health campaigns focused on educating community members about the importance of early HIV testing for infants and children under 5.

Abstract
INTRODUCTION Less than 10% of HIV positive children are enrolled into antiretroviral treatment program in the country. Provider-initiated testing and counseling was introduced to increasing uptake of HIV testing. The aim of this study is to determine the acceptability and factors undermining the acceptance of this laudable initiative by parents/caregivers of children attending paediatric out patient clinical services in our health institution. METHODS A cross sectional study of children aged 18 months to 18 years and their parents/caregivers attending paediatric outpatient clinic of the hospital was undertaken for the above objectives. RESULTS There were statistically more female parents/caregivers (82.5%, p=0.00), more male patients (52.9 %, p= 0.02), and 11.9% adolescents in this study. While 91.7% of parents/caregivers admitted not having knowledge of provider-initiated testing and counseling, 95.6% knew what HIV was. Acceptance of the program was high (98.7%), majority (89.7%) wanting to know the HIV status of their children/wards. Non-acceptance was small (1.2%), there main reason being prior knowledge of their HIV status. Prevalence of HIV among tested children was 1.7%. There was a strong relationship between having willingness to test for HIV and many of the study variables with religion of the parents/caregivers having the strongest relationship [OR: 13.94, (CI 1.82, 55.34)], and tribe having list association, [OR: 3.60, (CI 1.85, 17.14)]. CONCLUSION There was general wiliness to accept HIV test for children by their parents/caregiver in this study, and HIV prevalence in children is on a downward trend; its sustenance to be continued and adolescent clinics need to be created.

Abstract
To identify missed opportunities in HIV prevention, diagnosis, and linkage to care, we enrolled 183 hospitalized, HIV-infected, ART-naïve Kenyan children 0-12 years from four hospitals in Nairobi and Kisumu, and reviewed prevention of mother-to-child transmission of HIV (PMTCT), hospitalization, and HIV testing history. Median age was 1.8 years (IQR = 0.8, 4.5). Most mothers received HIV testing during pregnancy (77%). Among mothers tested, 60% and 40% reported HIV-negative and positive results, respectively; 33% of HIV-diagnosed mothers did not receive PMTCT antiretrovirals. First missed opportunities for pediatric diagnosis and linkage were due to failure to test mothers (23.1%), maternal HIV acquisition following initial negative test (45.7%), no early infant diagnosis (EID) or provider-initiated testing (PITC) (12.7%), late breastfeeding transmission (8.7%), failure to collect child HIV test results (1.2%), and no linkage to care following HIV diagnosis (8.7%). Among previously hospitalized children, 38% never received an HIV test. Strengthening initial and repeat maternal HIV testing and PITC are key interventions to prevent, detect, and treat pediatric HIV infections.

Abstract
BACKGROUND The CD4 cell count or percent (CD4%) at the start of combination antiretroviral therapy (cART) is an important prognostic factor in children starting therapy and an important indicator of program performance. We describe trends and determinants of CD4 measures at cART initiation in children from low-, middle-, and high-income countries. METHODS We included children aged <16 years from clinics participating in a collaborative study spanning sub-Saharan Africa, Asia, Latin America, and the United States. Missing CD4 values at cART start were estimated through multiple imputation. Severe immunodeficiency was defined according to World Health Organization criteria. Analyses used generalized additive mixed models adjusted for age, country, and calendar year. RESULTS A total of 34,706 children from 9 low-income, 6 lower middle-income, 4 upper middle-income countries, and 1 high-income country (United States) were included; 20,624 children (59%) had severe immunodeficiency. In low-income countries, the estimated prevalence of children starting cART with severe immunodeficiency declined from 76% in 2004 to 63% in 2010. Corresponding figures for lower middle-income countries were from 77% to 66% and for upper middle-income countries from 75% to 58%. In the United States, the percentage decreased from 42% to 19% during the period 1996 to 2006. In low- and middle-income countries, infants and children aged 12-15 years had the highest prevalence of severe immunodeficiency at cART initiation. CONCLUSIONS Despite progress in most low- and middle-income countries, many children continue to start cART with severe immunodeficiency. Early diagnosis and treatment of HIV-infected children to prevent morbidity and mortality associated with immunodeficiency must remain a global public health priority.

OBJECTIVES To assess the operation of voluntary counselling and testing (VCT) services forhuman immunodeficiency virus (HIV) in three cities in China. STUDY DESIGN A cross-sectional study using mixed methods, including focus group discussions,in-depth interviews, field assessment, archive checking and structured questionnaire interviews, was conducted to assess different aspects of VCT services. METHODS Surveys were undertaken in six counties of three China Global Fund AIDS Program (Round Five) cities, including 11 VCT clinics, 38 counsellors, 83 clients and 332 individuals at risk for HIV infection. RESULTS All counsellors were trained and approved for providing counselling. As there were adequate numbers of clinics and counsellors, VCT services ran smoothly. Clients were generally satisfied with VCT services and considered service operation to be adequate. Problems with the VCT programme included fewer VCT services in general hospitals, lack of a referral mechanism, and long delays between testing and receipt of results. CONCLUSIONS The operation of VCT services in the three cities was generally adequate, but referral services were poor. More attention needs to be paid to HIV testing and counselling in general hospitals, and referral networks need to be strengthened.

Temporal trends in the characteristics of children at antiretroviral therapy initiation in southern Africa: the IeDEA-SA Collaboration. PLoS One 2013; 8:e81037. [PMID: 24363808 PMCID: PMC3867284 DOI: 10.1371/journal.pone.0081037] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2013] [Accepted: 10/18/2013] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Since 2005, increasing numbers of children have started antiretroviral therapy (ART) in sub-Saharan Africa and, in recent years, WHO and country treatment guidelines have recommended ART initiation for all infants and very young children, and at higher CD4 thresholds for older children. We examined temporal changes in patient and regimen characteristics at ART start using data from 12 cohorts in 4 countries participating in the IeDEA-SA collaboration. METHODOLOGY/PRINCIPAL FINDINGS Data from 30,300 ART-naïve children aged <16 years at ART initiation who started therapy between 2005 and 2010 were analysed. We examined changes in median values for continuous variables using the Cuzick's test for trend over time. We also examined changes in the proportions of patients with particular disease severity characteristics (expressed as a binary variable e.g. WHO Stage III/IV vs I/II) using logistic regression. Between 2005 and 2010 the number of children starting ART each year increased and median age declined from 63 months (2006) to 56 months (2010). Both the proportion of children <1 year and ≥10 years of age increased from 12 to 19% and 18 to 22% respectively. Children had less severe disease at ART initiation in later years with significant declines in the percentage with severe immunosuppression (81 to 63%), WHO Stage III/IV disease (75 to 62%), severe anemia (12 to 7%) and weight-for-age z-score<-3 (31 to 28%). Similar results were seen when restricting to infants with significant declines in the proportion with severe immunodeficiency (98 to 82%) and Stage III/IV disease (81 to 63%). First-line regimen use followed country guidelines. CONCLUSIONS/SIGNIFICANCE Between 2005 and 2010 increasing numbers of children have initiated ART with a decline in disease severity at start of therapy. However, even in 2010, a substantial number of infants and children started ART with advanced disease. These results highlight the importance of efforts to improve access to HIV diagnostic testing and ART in children.

Abstract
BACKGROUND Limited access to HIV testing of children impedes early diagnosis and access to antiretroviral therapy. Our objective was to evaluate the feasibility and acceptability of routine pediatric HIV testing in an urban, fee-for-service, outpatient clinic in Durban, South Africa. METHODS We assessed the number of patients (0-15 years) who underwent HIV testing upon physician referral during a baseline period. We then established a routine, voluntary HIV testing study for pediatric patients, regardless of symptoms. Parents/caretakers were offered free rapid fingerstick HIV testing of their child. For patients <18 months, the biological mother was offered HIV testing and HIV DNA polymerase chain reaction was used to confirm the infant's status. The primary outcome was the HIV testing yield, defined as the average number of positive tests per month during the routine compared with the baseline period. RESULTS Over a 5-month baseline testing period, 931 pediatric patients registered for outpatient care. Of the 124 (13%) patients who underwent testing on physician referral, 21 (17%, 95% confidence interval: 11-25%) were HIV infected. During a 13-month routine testing period, 2790 patients registered for care and 2106 (75%) were approached for participation. Of these, 1234 were eligible and 771 (62%) enrolled. Among those eligible, 637 (52%, 95% confidence interval: 49-54%) accepted testing of their child or themselves (biological mothers of infants <18 months). There was an increase in the average number of HIV tests during the routine compared with the baseline HIV testing periods (49 versus 25 tests/month, P = 0.001) but no difference in the HIV testing yield during the testing periods (3 versus 4 positive HIV tests/month, P = 0.06). However, during the routine testing period, HIV prevalence remains extraordinarily high with 39 (6%, 95% confidence interval: 4-8%) newly diagnosed HIV-infected children (median 7 years, 56% female). CONCLUSIONS Targeted and symptom-based testing referral identifies an equivalent number of HIV-infected children as routine HIV testing. Routine HIV testing identifies a high burden of HIV and is a feasible and moderately acceptable strategy in an outpatient clinic in a high prevalence area.

Abstract
Background HIV counselling and testing and linkage to care are crucial for successful HIV prevention and treatment. Abbreviated counselling could save time; however, its effect on HIV risk is uncertain and methods to improve linkage to care have not been studied. Methods We did this factorial randomised controlled study at Mulago Hospital, Uganda. Participants were randomly assigned to abbreviated or traditional HIV counselling and testing; HIV-infected patients were randomly assigned to enhanced linkage to care or standard linkage to care. All study personnel except counsellors and the data officer were masked to study group assignment. Participants had structured interviews, given once every 3 months. We compared sexual risk behaviour by counselling strategy with a 6·5% non-inferiority margin. We used Cox proportional hazards analyses to compare HIV outcomes by linkage to care over 1 year and tested for interaction by sex. This trial is registered with ClinicalTrials.gov (NCT00648232). Findings We enrolled 3415 participants; 1707 assigned to abbreviated counselling versus 1708 assigned to traditional. Unprotected sex with an HIV discordant or status unknown partner was similar in each group (232/823 [27·9%] vs 251/890 [28·2%], difference −0·3%, one-sided 95% CI 3·2). Loss to follow-up was lower for traditional counselling than for abbreviated counselling (adjusted hazard ratio [HR] 0·61, 95% CI 0·44–0·83). 1003 HIV-positive participants were assigned to enhanced linkage (n=504) or standard linkage to care (n=499). Linkage to care did not have a significant effect on mortality or receipt of co-trimoxazole. Time to treatment in men with CD4 cell counts of 250 cells per μL or fewer was lower for enhanced linkage versus standard linkage (adjusted HR 0·60, 95% CI 0·41–0·87) and time to HIV care was decreased among women (0·80, 0·66–0·96). Interpretation Abbreviated HIV counselling and testing did not adversely affect risk behaviour. Linkage to care interventions might decrease time to enrolment in HIV care and antiretroviral treatment and thus might affect secondary HIV transmission and improve treatment outcomes.

Abstract
Family-centred HIV care models have emerged as an approach to better target children and their caregivers for HIV testing and care, and further provide integrated health services for the family unit's range of care needs. While there is significant international interest in family-centred approaches, there is a dearth of research on operational experiences in implementation and scale-up. Our retrospective case study examined best practices and enabling factors during scale-up of family-centred care in ten health facilities and ten community clinics supported by a non-governmental organization, Mildmay, in Central Uganda. Methods included key informant interviews with programme management and families, and a desk review of hospital management information systems (HMIS) uptake data. In the 84 months following the scale-up of the family-centred approach in HIV care, Mildmay experienced a 50-fold increase of family units registered in HIV care, a 40-fold increase of children enrolled in HIV care, and nearly universal coverage of paediatric cotrimoxazole prophylaxis. The Mildmay experience emphasizes the importance of streamlining care to maximize paediatric capture. This includes integrated service provision, incentivizing care-seeking as a family, creating child-friendly service environments, and minimizing missed paediatric testing opportunities by institutionalizing early infant diagnosis and provider-initiated testing and counselling. Task-shifting towards nurse-led clinics with community outreach support enabled rapid scale-up, as did an active management structure that allowed for real-time review and corrective action. The Mildmay experience suggests that family-centred approaches are operationally feasible, produce strong coverage outcomes, and can be well-managed during rapid scale-up.

Abstract
OBJECTIVES To review and summarize the essential components of HIV treatment and care services in low and middle-income countries (LMICs). METHODS Literature review and reflection on programmatic experience. FINDINGS There is increasing recognition that the essential 'package' of HIV care must include early identification of HIV-positive people in need of care, appropriate initial and continued counselling, assessment of HIV disease stage, treatment with HAART for those who need it, monitoring while on treatment for efficacy, adherence and side-effects, detection and management of other complications of HIV infection, provision of sexual and reproductive health services as well as careful record-keeping. The impressive scale-up of HIV treatment and care services has required decentralization of service provision linked to task-shifting. But the future holds even greater challenges, as the number of people in need of HIV care continues to rise at a time when many traditional donors and governments in the most-affected regions have reduced budgets. CONCLUSION In the long-term, the increased demand for HIV-care services can only be satisfied through increased decentralisation to peripheral health units, with the role of each type of unit being appropriate to the human and material resources available to it.HIV-care services can also naturally integrate with the care of chronic noncommunicable diseases and with closely related services like mother and child health, and thus should promote a shift from vertical to integrated programming. Staff training and support around a set of evidence-based policies and guidelines and a reliable supply of essential medicines and supplies are further essential components for a successful programme.

Associations between mode of HIV testing and consent, confidentiality, and referral: a comparative analysis in four African countries. PLoS Med 2012; 9:e1001329.

Abstract
BACKGROUND Recommendations about scaling up HIV testing and counseling highlight the need to provide key services and to protect clients' rights, but it is unclear to what extent different modes of testing differ in this respect. This paper examines whether practices regarding consent, confidentiality, and referral vary depending on whether testing is provided through voluntary counseling and testing (VCT) or provider-initiated testing. METHODS AND FINDINGS The MATCH (Multi-Country African Testing and Counseling for HIV) study was carried out in Burkina Faso, Kenya, Malawi, and Uganda. Surveys were conducted at selected facilities. We defined eight outcome measures related to pre- and post-test counseling, consent, confidentiality, satisfactory interactions with providers, and (for HIV-positive respondents) referral for care. These were compared across three types of facilities: integrated facilities, where testing is provided along with medical care; stand-alone VCT facilities; and prevention of mother-to-child transmission (PMTCT) facilities, where testing is part of PMTCT services. Tests of bivariate associations and modified Poisson regression were used to assess significance and estimate the unadjusted and adjusted associations between modes of testing and outcome measures. In total, 2,116 respondents tested in 2007 or later reported on their testing experience. High percentages of clients across countries and modes of testing reported receiving recommended services and being satisfied. In the unadjusted analyses, integrated testers were less likely to meet with a counselor before testing (83% compared with 95% of VCT testers; p<0.001), but those who had a pre-test meeting were more likely to have completed consent procedures (89% compared with 83% among VCT testers; p<0.001) and pre-test counseling (78% compared with 73% among VCT testers; p = 0.015). Both integrated and PMTCT testers were more likely to receive complete post-test counseling than were VCT testers (59% among both PMTCT and integrated testers compared with 36% among VCT testers; p<0.001). Adjusted analyses by country show few significant differences by mode of testing: only lower satisfaction among integrated testers in Burkina Faso and Uganda, and lower frequency of referral among PMTCT testers in Malawi. Adjusted analyses of pooled data across countries show a higher likelihood of pre-test meeting for those testing at VCT facilities (adjusted prevalence ratio: 1.22, 95% CI: 1.07-1.38) and higher satisfaction for stand-alone VCT facilities (adjusted prevalence ratio: 1.15; 95% CI: 1.06-1.25), compared to integrated testing, but no other associations were statistically significant. CONCLUSIONS Overall, in this study most respondents reported favorable outcomes for consent, confidentiality, and referral. Provider-initiated ways of delivering testing and counseling do not appear to be associated with less favorable outcomes for clients than traditional, client-initiated VCT, suggesting that testing can be scaled up through multiple modes without detriment to clients' rights.

Abstract
BACKGROUND Provider-initiated HIV testing and counselling (PITC) is widely recommended to ensure timely treatment of HIV. The Zimbabwe Ministry of Health introduced PITC in 2007. We aimed to evaluate institutional capacity to implement PITC and investigate patient and health care worker (HCW) perceptions of the PITC programme. METHODS Purposive selection of health care institutions was conducted among those providing PITC. Study procedures included 1) assessment of implementation procedures and institutional capacity using a semi-structured questionnaire; 2) in-depth interviews with patients who had been offered HIV testing to explore perceptions of PITC, 3) Focus group discussions with HCW to explore views on PITC. Qualitative data was analysed according to Framework Analysis. RESULTS Sixteen health care institutions were selected (two central, two provincial, six district hospitals; and six primary care clinics). All institutions at least offered PITC in part. The main challenges which prevented optimum implementation were shortages of staff trained in PITC, HIV rapid testing and counselling; shortages of appropriate counselling space, and, at the time of assessment, shortages of HIV test kits. Both health care workers and patients embraced PITC because they had noticed that it had saved lives through early detection and treatment of HIV. Although health care workers reported an increase in workload as a result of PITC, they felt this was offset by the reduced number of HIV-related admissions and satisfaction of working with healthier clients. CONCLUSION PITC has been embraced by patients and health care workers as a life-saving intervention. There is need to address shortages in material, human and structural resources to ensure optimum implementation.

Abstract
Background Provider-initiated testing and counselling (PITC) is a priority strategy for increasing access for HIV-exposed children to prevention measures, and infected children to treatment and care interventions. This article examines efforts to scale-up paediatric PITC at a second-level hospital located in Zambia’s Southern Province, and serving a catchment area of 1.2 million people. Methods and Principal Findings Our retrospective case study examined best practices and enabling factors for rapid institutionalization of PITC in Livingstone General Hospital. Methods included clinical observations, key informant interviews with programme management, and a desk review of hospital management information systems (HMIS) uptake data following the introduction of PITC. After PITC roll-out, the hospital experienced considerably higher testing uptake. In a 36-month period following PITC institutionalization, of total inpatient children eligible for PITC (n = 5074), 98.5% of children were counselled, and 98.2% were tested. Of children tested (n = 4983), 15.5% were determined HIV-infected; 77.6% of these results were determined by DNA polymerase chain reaction (PCR) testing in children under the age of 18 months. Of children identified as HIV-infected in the hospital’s inpatient and outpatient departments (n = 1342), 99.3% were enrolled in HIV care, including initiation on co-trimoxazole prophylaxis. A number of good operational practices and enabling factors in the Livingstone General Hospital experience can inform rapid PITC institutionalization for inpatient and outpatient children. These include the placement of full-time nurse counsellors at key areas of paediatric intake, who interface with patients immediately and conduct testing and counselling. They are reinforced through task-shifting to peer counsellors in the wards. Nurse counsellor capacity to draw specimen for DNA PCR for children under 18 months has significantly enhanced early infant diagnosis. The hospital’s bolstered antiretroviral supply chain, package of on-site HIV services, and follow-up care for children and families improved the continuum of service uptake. Conclusions and Significance The clinical impact and operational experience emphasizes that institutional PITC is a feasible strategy for increasing access to paediatric HIV care, particularly in generalized epidemic settings.

Abstract
OBJECTIVE To assess the contribution of provider-initiated testing and counselling (PITC) to achieving universal testing of pregnant women and, from available data on components of PITC, assess whether PITC adoption adheres to pre-test information, post-test counselling procedures and linkage to treatment. METHODS Systematic review of published literature. Findings were collated and data extracted on HIV testing uptake before and after the adoption of a PITC model. Data on pre- and post-test counselling uptake and linkage to anti-retrovirals, where available, were also extracted. RESULTS Ten eligible studies were identified. Pre-intervention testing uptake ranged from 5.5% to 78.7%. Following PITC introduction, testing uptake increased by a range of 9.9% to 65.6%, with testing uptake ≥85% in eight studies. Where reported, pre-test information was provided to between 91.5% and 100% and post-test counselling to between 82% and 99.8% of pregnant women. Linkage to ARVs for prevention of mother to child transmission (PMTCT) was reported in five studies and ranged from 53.7% to 77.2%. Where reported, PITC was considered acceptable by ANC attendees. CONCLUSION Our review provides evidence that the adoption of PITC within ANC can facilitate progress towards universal voluntary testing of pregnant women. This is necessary to increase the coverage of PMTCT services and facilitate access to treatment and prevention interventions. We found some evidence that PITC adoption does not undermine processes inherent to good conduct of testing, with high levels of pre-test information and post-test counselling, and two studies suggesting that PITC is acceptable to ANC attendees.

Abstract
Early infant diagnosis (EID) of HIV-1 infection confers substantial benefits to HIV-infected and HIV-uninfected infants, to their families, and to programs providing prevention of mother-to-child transmission (PMTCT) services, but has been challenging to implement in resource-limited settings. In order to correctly inform parents/caregivers of infant infection status and link HIV-infected infants to care and treatment, a 'cascade' of events must successfully occur. A frequently cited barrier to expansion of EID programs is the cost of the required laboratory assays. However, substantial implementation barriers, as well as personnel and infrastructure requirements, exist at each step in the cascade. In this update, we review challenges to uptake at each step in the EID cascade, highlighting that even with the highest reported levels of uptake, nearly half of HIV-infected infants may not complete the cascade successfully. We next synthesize the available literature about the costs and cost effectiveness of EID programs; identify areas for future research; and place these findings within the context of the benefits and challenges to EID implementation in resource-limited settings.

Abstract
BACKGROUND Routine Human Immunodeficiency Virus (HIV) testing, called provider-initiated opt-out HIV testing and counseling (PITC), is recommended in African countries with high HIV prevalence. However, it is unknown whether PITC increases access to pediatric HIV care. In 2008, the Baylor International Pediatric AIDS Initiative implemented PITC (BIPAI-PITC) at a Malawian hospital. We sought to evaluate the influence of BIPAI-PITC, compared with nonroutine HIV testing (NRT), on pediatric HIV care access. METHODS Retrospective data from 7077 pediatric inpatients were collected during sequential 4-month periods of NRT and BIPAI-PITC. In-hospital and 1-year outcomes for 337 HIV-infected and HIV-exposed uninfected inpatients not previously enrolled in HIV care were analyzed to assess the clinical influence of each testing strategy. RESULTS During BIPAI-PITC, a greater proportion of all hospitalized children received HIV testing (81.0% vs. 33.3%, P < 0.001), accessed inpatient HIV-trained care (7.5% vs. 2.4%, P < 0.001), enrolled into an outpatient HIV clinic after discharge (3.2% vs. 1.3%, P < 0.001), and initiated antiretroviral therapy (ART) after hospitalization (1.1% vs. 0.6%, P = 0.010) compared with NRT. Additionally, BIPAI-PITC increased the proportion of hospitalized HIV-infected and HIV-exposed uninfected children receiving DNA polymerase chain reaction testing (73.5% vs. 35.2%, P < 0.001), but did not improve outpatient enrollment or ART initiation of identified HIV-infected patients. CONCLUSIONS BIPAI-PITC increases access to inpatient and outpatient pediatric HIV care for hospitalized children, including DNA polymerase chain reaction testing and ART. Broader implementation of BIPAI-PITC or similar approaches, along with more pediatric HIV-trained clinicians and improved defaulter-tracking methods, would improve pediatric HIV service utilization globally.

Task shifting routine inpatient pediatric HIV testing improves program outcomes in urban Malawi: a retrospective observational study. PLoS One 2010; 5:e9626. [PMID: 20224782 PMCID: PMC2835755 DOI: 10.1371/journal.pone.0009626] [Citation(s) in RCA: 59] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2009] [Accepted: 02/14/2010] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND This study evaluated two models of routine HIV testing of hospitalized children in a high HIV-prevalence resource-constrained African setting. Both models incorporated "task shifting," or the allocation of tasks to the least-costly, capable health worker. METHODS AND FINDINGS Two models were piloted for three months each within the pediatric department of a referral hospital in Lilongwe, Malawi between January 1 and June 30, 2008. Model 1 utilized lay counselors for HIV testing instead of nurses and clinicians. Model 2 further shifted program flow and advocacy responsibilities from counselors to volunteer parents of HIV-infected children, called "patient escorts." A retrospective review of data from 6318 hospitalized children offered HIV testing between January-December 2008 was conducted. The pilot quarters of Model 1 and Model 2 were compared, with Model 2 selected to continue after the pilot period. There was a 2-fold increase in patients offered HIV testing with Model 2 compared with Model 1 (43.1% vs 19.9%, p<0.001). Furthermore, patients in Model 2 were younger (17.3 vs 26.7 months, p<0.001) and tested sooner after admission (1.77 vs 2.44 days, p<0.001). There were no differences in test acceptance or enrollment rates into HIV care, and the program trends continued 6 months after the pilot period. Overall, 10244 HIV antibody tests (4779 maternal; 5465 child) and 453 DNA-PCR tests were completed, with 97.8% accepting testing. 19.6% of all mothers (n = 1112) and 8.5% of all children (n = 525) were HIV-infected. Furthermore, 6.5% of children were HIV-exposed (n = 405). Cumulatively, 72.9% (n = 678) of eligible children were evaluated in the hospital by a HIV-trained clinician, and 68.3% (n = 387) successfully enrolled into outpatient HIV care. CONCLUSIONS/SIGNIFICANCE The strategy presented here, task shifting from lay counselors alone to lay counselors and patient escorts, greatly improved program outcomes while only marginally increasing operational costs. The wider implementation of this strategy could accelerate pediatric HIV care access in high-prevalence settings.
