RESUMEN
Understanding motivations and resilience-associated factors that help people newly diagnosed with HIV link to care is critical in the context of universal test and treat. We analyzed 30 in-depth interviews (IDI) among adults aged 18 and older in western Kenya diagnosed with HIV during home-based counseling and testing and who had linked to HIV care. A directed content analysis was performed, categorizing IDI quotations into a table based on linkage stages for organization and then developing and applying codes from self-determination theory and the concept of resilience. Autonomous motivations, including internalized concerns for one's health and/or to provide care for family, were salient facilitators of accessing care. Controlled forms of motivation, such as fear or external pressure, were less salient. Social support was an important resilience-associated factor fostering linkage. HIV testing and counseling programs which incorporate motivational interviewing that emphasizes motivations related to one's health or family combined with a social support/navigator approach, may promote timely linkage to care.

OBJECTIVE: To compare the incidence of HIV, death, and abuse among orphaned children to nonorphaned children living in households caring for orphaned children in Western Kenya. STUDY DESIGN: A random sample was taken of 300 households caring for at least one orphaned child in Uasin Gishu County, Kenya. All orphaned and nonorphaned children in each selected household were enrolled in a prospective cohort study between 2010 and 2013. A total of 1488 children (487 double orphans, 743 single orphans, and 258 nonorphans) were followed up annually until 2019. Survival analysis was used to estimate hazard ratios and 95% confidence intervals (CIs) of the association between the number of parents the child had lost (none, 1, or 2), and HIV incidence, death, combined HIV incidence or death, and incident abuse. RESULTS: Among 1488 children enrolled, 52% of participants were females, 23 were HIV positive, and the median age was 10.4 years. Over the course of the study, 16 orphaned children died and 11 acquired HIV. No deaths or incident HIV infections were observed among the nonorphaned children. Among children who were HIV negative at enrollment, loss of a parent was strongly associated with incident HIV (adjusted hazard ratio: 2.21 per parent lost, 95% CI: 1.03-4.73) and HIV or death (adjusted hazard ratio: 2.46 per parent lost, 95% CI: 1.37-4.42). There were no significant associations between orphan level and abuse. CONCLUSIONS: In similar households, orphaned children experience a higher risk of HIV and death than nonorphaned children. Both orphaned children and the families caring for them need additional support to prevent adverse health outcomes.

Adolescents in sub-Saharan Africa, specifically adolescent girls and young women, young men who have sex with men, transgender persons, persons who use substances, and adolescents experiencing homelessness experience intersectional stigma, have a high incidence of HIV and are less likely to be engaged in HIV prevention and care. We conducted a thematic analysis informed by the Health and Discrimination Framework using a multiple case study design with five case studies in 3 sub-Saharan African countries. Our analysis found commonalities in adolescents' intersectional stigma experiences across cases, despite different contexts. We characterize how intersectional stigma impacts the uptake and implementation of HIV prevention and treatment services along the continuum for adolescents. Findings reveal how intersectional stigma operates across social-ecological levels and worsens HIV-related outcomes for adolescents. We identify opportunities for implementation science research to address stigma-related barriers to the uptake and delivery of HIV services for adolescents in sub-Saharan Africa.

Implementation science (IS) uses systematic methods to close gaps between research and practice by identifying and addressing barriers to implementation of evidence-based interventions (EBIs). To reach UNAIDS HIV targets, IS can support programs to reach vulnerable populations and achieve sustainability. We studied the application of IS methods in 36 study protocols that were part of the Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA). Protocols focused on youth, caregivers, or healthcare workers in high HIV-burden African countries and evaluated medication, clinical and behavioral/social EBIs. All studies measured clinical outcomes and implementation science outcomes; most focused on early implementation outcomes of acceptability (81%), reach (47%), and feasibility (44%). Only 53% used an implementation science framework/theory. Most studies (72%) evaluated implementation strategies. Some developed and tested strategies, while others adapted an EBI/strategy. Harmonizing IS approaches allows cross study learning and optimization of delivery of EBIs and could support attainment of HIV goals.

Adolescent mental health (AMH) is a critical driver of HIV outcomes, but is often overlooked in HIV research and programming. The implementation science Exploration, Preparation, Implementation, Sustainment (EPIS) framework informed development of a questionnaire that was sent to a global alliance of adolescent HIV researchers, providers, and implementors working in sub-Saharan Africa with the aim to (1) describe current AMH outcomes incorporated into HIV research within the alliance; (2) identify determinants (barriers/gaps) of integrating AMH into HIV research and care; and (3) describe current AMH screening and referral systems in adolescent HIV programs in sub-Saharan Africa. Respondents reported on fourteen named studies that included AMH outcomes in HIV research. Barriers to AMH integration in HIV research and care programs were explored with suggested implementation science strategies to achieve the goal of integrated and sustained mental health services within adolescent HIV programs.

Adolescents and sexual minority men (SMM) are high priority groups in the United Nations' 2021 - 2016 goals for HIV prevention and viral load suppression. Interventions aimed at optimizing HIV prevention, testing and viral load suppression for adolescents must also attend to the intersectional realities influencing key sub-populations of SMM. Consequently, there is not a robust evidence-base to guide researchers and program partners on optimal approaches to implementing interventions with adolescent SMM. Using a multiple case study design, we integrated the Implementation Research Logic Model with components of the Consolidated Framework for Implementation Research and applied it as a framework for a comparative description of ten HIV related interventions implemented across five countries (Ghana, Kenya, Nigeria, Tanzania and United States). Using self-reported qualitative survey data of project principal investigators, we identified 17 of the most influential implementation determinants as well as a range of 17 strategies that were used in 90 instances to support intervention implementation. We highlight lessons learned in the implementation research process and provide recommendations for researchers considering future HIV implementation science studies with adolescent SMM.

BACKGROUND: Street-connected individuals (SCI) in Kenya experience barriers to accessing HIV care. This pilot study provides proof-of-concept for Enabling Adherence to Treatment (EAT), a combination intervention providing modified directly observed therapy (mDOT), daily meals, and peer navigation services to SCI living with HIV or requiring therapy for other conditions (e.g. tuberculosis). The goal of the EAT intervention was to improve engagement in HIV care and viral suppression among SCI living with HIV in an urban setting in Kenya. METHODS: This pilot study used a single group, pre/post-test design, and enrolled a convenience sample of self-identified SCI of any age. Participants were able to access free hot meals, peer navigation services, and mDOT 6 days per week. We carried out descriptive statistics to characterize participants' engagement in EAT and HIV treatment outcomes. We used McNemar's chi-square test to calculate unadjusted differences in HIV outcomes pre- and post-intervention among participants enrolled in HIV care prior to EAT. We compared unadjusted time to initiation of antiretroviral therapy (ART) and first episode of viral load (VL) suppression among participants enrolled in HIV care prior to EAT vs. concurrently with EAT using the Wilcoxon rank sum test. Statistical significance was defined as p < 0.05. We calculated total, fixed, and variable costs of the intervention. RESULTS: Between July 2018 and February 2020, EAT enrolled 87 participants: 46 (53%) female and 75 (86%) living with HIV. At baseline, 60 out of 75 participants living with HIV (80%) had previously enrolled in HIV care. Out of 60, 56 (93%) had initiated ART, 44 (73%) were active in care, and 25 (42%) were virally suppressed (VL < 1000 copies/mL) at their last VL measure in the 19 months before EAT. After 19 months of follow-up, all 75 participants living with HIV had enrolled in HIV care and initiated ART, 65 (87%) were active in care, and 44 (59%) were virally suppressed at their last VL measure. Among the participants who were enrolled in HIV care before EAT, there was a significant increase in the proportion who were active in HIV care and virally suppressed at their last VL measure during EAT enrollment compared to before EAT enrollment. Participants who enrolled in HIV care concurrently with EAT had a significantly shorter time to initiation of ART and first episode of viral suppression compared to participants who enrolled in HIV care prior to EAT. The total cost of the intervention over 19 months was USD $57,448.64. Fixed costs were USD $3623.04 and variable costs were USD $63.75/month/participant. CONCLUSIONS: This pilot study provided proof of concept that EAT, a combination intervention providing mDOT, food, and peer navigation services, was feasible to implement and may support engagement in HIV care and achievement of viral suppression among SCI living with HIV in an urban setting in Kenya. Future work should focus on controlled trials of EAT, assessments of feasibility in other contexts, and cost-effectiveness studies.

BACKGROUND: Given the high burden of adverse sexual and reproductive health outcomes (SRH) and low levels of school attendance among adolescent girls in Kenya, this study sought to elucidate the association between school attendance and SRH outcomes among adolescent girls in Homa Bay and Narok counties. METHODS: This study uses baseline quantitative data from the mixed-methods evaluation of the In Their Hands (ITH) program which occurred between September to October 2018 in Homa Bay and Narok counties. In total, 1840 adolescent girls aged 15-19 years participated in the baseline survey, of which 1810 were included in the present analysis. Multivariable logistic regression models were used to assess the association between school attendance (in- versus out-of-school) and ever having sex, condom use during last sex, and ever pregnant, controlling for age, orphan status, income generation, religion, county, relationship status, and correct SRH knowledge. RESULTS: Across the 1810 participants included in our study, 61.3% were in-school and 38.7% were out-of-school. Compared to adolescent girls who were in-school, those out-of-school were more likely (AOR 5.74 95% CI 3.94, 8.46) to report ever having sex, less likely (AOR: 0.21, 95% CI 0.16, 0.31) to have used a condom during their last sexual intercourse, and more likely (AOR: 6.98, 95% CI 5.04, 9.74) to have ever been pregnant. CONCLUSIONS: School attendance plays an integral role in adolescent girls' SRH outcomes, and it is imperative that policy actors coordinate with the government and community to develop and implement initiatives that support adolescent girls' school attendance and education.
Adolescent girls in Kenya experience poor sexual and reproductive health outcomes (SRH) and have low levels of educational attainment. In this study, we aimed to examine if school attendance was associated with sexual and reproductive health outcomes among adolescent girls aged 15 to 19 years in Homa Bay and Narok counties in Kenya. The study used data from the evaluation of the In Their Hands (ITH) program which occurred between September to October 2018. A total of 1840 adolescent girls years participated in the baseline survey, of which 1810 were included in this study. We found that compared to adolescent girls in-school, those who were out-of-school were significantly more likely to report ever having sex, less likely to have used a condom during their last intercourse, and more likely to have ever been pregnant. This study found that attending school plays an important protective role in the SRH of adolescent girls. Therefore, it is important to develop and implement initiatives to support adolescent girls' school attendance, and ultimately their education attainment.

We sought to determine the relationship between continuity of care and adherence to clinic appointments among patients receiving HIV care in high vs. low clinician-to-patient (C:P) ratios facilities in western Kenya. This retrospective analysis included 12,751 patients receiving HIV care from the Academic Model Providing Access to Healthcare (AMPATH) program, between February 2016-2019. We used logistic regression analysis with generalized estimating equations to estimate the relationship between continuity of care (two consecutive visits with the same provider) and adherence to clinic appointments (within 7 days of a scheduled appointment) over time. Adjusting for covariates, patients in low C:P ratio facilities who had continuity of care, were more likely to be adherent to their appointments compared to those without continuity (adjusted odds ratio = 1.50; 95% confidence interval, 1.33-1.69). Continuity in HIV care may be a factor in clinical adherence among patients in low C:P ratio facilities and should therefore be promoted.

BACKGROUND: There are approximately 140 million orphaned and separated children (OSCA) around the world. In Kenya, many of these children live with extended family while others live in institutions. Despite evidence that orphans are less likely to be enrolled in school than non-orphans, there is little evidence regarding the role of care environment. This evidence is vital for designing programs and policies that promote access to education for orphans, which is not only their human right but also an important social determinant of health. The purpose of this study was to compare educational attainment among OSCA living in Charitable Children's Institutions and family-based settings in Uasin Gishu County, Kenya. METHODS: This study analyses follow up data from a cohort of OSCA living in 300 randomly selected households and 17 institutions. We used Poisson regression to estimate the effect of care environment on primary school completion among participants age ≥ 14 as well as full and partial secondary school completion among participants age ≥ 18. Risk ratios and 95% confidence intervals were estimated using a bootstrap method with 1000 replications. RESULTS: The analysis included 1406 participants (495 from institutions, 911 from family-based settings). At baseline, 50% were female, the average age was 9.5 years, 54% were double orphans, and 3% were HIV-positive. At follow-up, 76% of participants age ≥ 14 had completed primary school and 32% of participants age ≥ 18 had completed secondary school. Children living in institutions were significantly more likely to complete primary school (aRR: 1.18, 95% CI: 1.10-1.28) and at least 1 year of secondary school (aRR: 1.28, 95% CI: 1.18-1.39) than children in family-based settings. Children living in institutions were less likely to have completed all 4 years secondary school (aRR: 0.79, 95% CI: 0.43-1.18) than children in family-based settings. CONCLUSION: Children living in institutional environments were more likely to complete primary school and some secondary school than children living in family-based care. Further support is needed for all orphans to improve primary and secondary school completion. Policies that require orphans to leave institution environments upon their eighteenth birthday may be preventing these youth from completing secondary school.

INTRODUCTION: UNICEF estimates that there are as many as 100 million street-involved youth (SIY) globally. Marginalized conditions put SIY at higher risk of HIV and adverse outcomes once HIV-positive. The objective of this analysis was to describe barriers and facilitators of accessing HIV prevention, testing, and treatment services as Phase I of an implementation study evaluating the use of peer navigators to increase access to HIV services. METHODS: Semi-structured interviews, focus group discussions (FGD), and theatre testing were conducted with individuals who identify as SIY, health care providers, and community stakeholders living in Canada (Toronto, Montreal, London) and Kenya (Eldoret, Huruma, Kitale). Data were analyzed using a directed content approach, guided by the socio-ecological model (SEM). RESULTS: Across the six sites were 195 participants: 64 SIY, 42 healthcare providers, and 97 community-based stakeholders. Barriers were identified at the societal (e.g. intersectional stigma and discrimination), public policy (e.g., inadequate access to basic needs, legal documentation, lack of health insurance, and limited community-based funding), institutional (e.g. lack of inclusive education and training, inadequate HIV educational outreach, and restrictive service provision), interpersonal (e.g., ineffective communication from healthcare providers), and intrapersonal levels (e.g. lack of trust and associated fear, low perception for healthcare, and lack of self-esteem). These contributed to limited HIV services utilization among SIY. Conversely, numerous facilitators were also identified at the public policy (e.g. affordable HIV services and treatment), institutional (e.g. available and accessible HIV prevention tools, HIV education and awareness programs, and holistic models of care), interpersonal level (e.g., systems navigation support, peer support, and personal relationships), and intrapersonal levels (e.g. self-efficacy) as positively supporting SIY access to HIV services. CONCLUSION: Intersectional stigma was a critical barrier in all sites, and policies and programs that foster welcoming environments for youth from diverse backgrounds and living circumstances may be better able to respond to the HIV service needs of this high risk population. Social support and navigation services were reported to facilitate access to HIV services in all sites.

BACKGROUND: Institutionalization has shown contradictory effects on the mental health of orphaned and separated children and adolescents (OSCA) in sub-Saharan Africa. There is a paucity of data surrounding the cost-effectiveness of different care environments for improving OSCA's mental health. AIMS OF THE STUDY: The goal of this analysis was to evaluate the cost-effectiveness of Charitable Children's Institutions (orphanages) compared to family-based settings serving OSCA in East Africa in terms of USD/unit reduction in mental health diagnoses (depression, anxiety, post-traumatic stress disorder, suicidality) and quality-adjusted life-year (QALY) gained. METHODS: This economic analysis was conducted from a societal perspective as part of the Orphaned and Separated Children's Assessments Related to their (OSCAR's) Health and Well-Being Project, a 10-year longitudinal cohort study evaluating the effects of different care environments on OSCA's physical and psychological health in western Kenya. Cost data were ascertained from 9 institutions and 225 family-based settings in the OSCAR cohort via survey assessments, budget reports, and expert interviews. Monthly per-child costs were calculated as the sum of recurrent and capital costs divided by the environment's maximum residential capacity, and cost differences between care environments were estimated using two-part models. Mental health effectiveness outcomes were derived from prior survival regression analyses conducted among the OSCAR cohort. We used Child Depression Inventory Short-Form scores at baseline and follow-up to calculate the number of depression-free days (DFDs) over the follow-up period, and translated DFDs into QALYs using established utility weights. Incremental cost-effectiveness ratios (ICERs) were calculated as the difference in monthly per-child cost divided by the difference in each mental health outcome, comparing institutions to family-based settings. Sampling uncertainty in the ICERs was handled using nonparametric bootstrapping with 1,000 replications. We assumed a willingness-to-pay threshold of three times Kenya's per capita gross domestic product. RESULTS: Charitable Children's Institutions cost USD 123 more on average than family-based settings in terms of monthly per-child expenditures (p<0.001). Compared to family-based care, institutional care resulted in an ICER of USD 236, USD 280, USD 397, and USD 456 per unit reduction in depression, anxiety, PTSD, and suicidal diagnosis among OSCA, respectively. The incremental cost per additional QALY was USD 4,929 (95% CI: USD 3096 -- USD 6740). The probability of Charitable Children's Institutions being more cost-effective than family-based settings was greater than 90% for willingness-to-pay thresholds above USD 7,000/QALY. DISCUSSION: Only a subset of institutions in the cohort were willing to provide budgetary information for this assessment, which potentially biased our cost estimates. However, institutions who did not provide budget data likely had lower expenditures than those for whom cost data were collected, leading to more conservative cost estimates. Furthermore, our QALY estimates were based solely on depression-free days such that OSCA in institutions may experience added mental health benefits for no additional costs. IMPLICATIONS FOR HEALTH POLICY: Compared to family-based settings, institutions may be more cost-effective for improving mental health outcomes among orphaned and separated children and adolescents. Our findings suggest that policy-makers should prioritize resources to strengthen family-based care but that formal institutions can offer cost-effective, mental health support as a last resort.

HIV has transformed from a serious acute illness with high rates of morbidity and mortality to a fairly easily managed chronic disease. However, children and adolescents living with HIV are yet to achieve similar improvement in their HIV care outcomes compared to adults. There have been a number of studies assessing the reasons for slower improvement in these age categories, mainly focusing on health systems, drug- and family- related barriers to ART adherence in children. We sought to explore school-related barriers to adherence through in-depth interviews with students living with HIV (SLHIV) aged 13-17 years who had fully disclosed their HIV status in western Kenya. Data was analysed using NVivo 8™. The study found that stigmatisation in the form of negative discussions and alienation, fear of unintended disclosure (due to the drug packaging and lack of privacy while taking their pills) were barriers to ART adherence among these SLHIV. Other barriers included challenges with drug storage while in school and the complexity of coordinating school and clinic-related activities and a lack of structured support systems in schools. In addition to hindering their adherence to ART, these barriers resulted in negative emotions (anger, sadness, frustration) and affected school performance. This study found fairly serious barriers to ART adherence among SLHIV, which calls for structured communication and coordinated support between government ministries of health and education in Kenya.

BACKGROUND: Children of street-connected women in Kenya are at risk of child maltreatment. There have been increasing calls for positive parenting programs for parents experiencing homelessness, however never has one been implemented with this population. We therefore adapted the evidence-based Parenting for Lifelong Health for Young Children program using participatory methods, and piloted the adapted program with street-connected mothers in Kenya. OBJECTIVES: To (a) determine if the adapted program was feasible and acceptable with street-connected mothers, and (b) assess indicative effects on child maltreatment, positive parenting, and parental stress. PARTICIPANTS AND SETTING: Two groups of 15 mothers (ages 19+, and 20- ) participated between June-July 2018 in Eldoret, Kenya. Participants were eligible if they (a) were the mother of at least one child and (b) self-identified as street-connected. METHODS: Feasibility was measured via enrollment, attendance, drop-out rates, and engagement in take-away activities. Focus groups explored program acceptability and program outcomes. Self-report surveys assessed pre-post changes in child maltreatment, parental stress, parental sense of inefficacy, and positive parenting practices. RESULTS: 70% of participants attended ≥3/4 of sessions, 10% dropped out, and >50% of take-away activities were completed. Participants reported high acceptability and requested its continuation for themselves and other parents. There was an increase in supporting good behaviour (t(21)=8.15, p < .000) and setting limits (t(18) = 10.03, p < .000); a reduction in physical abuse (t(23) = -2.15, p = .042) and parental stress (t(22) = -7.08, p < .000); results for parental inefficacy were not statistically significant (t(22) = 0.15, p = .882). CONCLUSIONS: The adapted program is feasible and acceptable to street-connected mothers, and may reduce child maltreatment and parental stress, and increase positive parenting. Further research should test program effectiveness.
RESUMEN
BACKGROUND: The objective of this study was to estimate the prevalence, incidence and risk factors for pregnancy among HIV-positive adolescents in a large HIV treatment program in western Kenya. METHODS: The Academic Model Providing Access to Healthcare (AMPATH) program is a partnership between Moi University, Moi Teaching and Referral Hospital and a consortium of 11 North American academic institutions. AMPATH currently provides care to 85,000 HIV-positive individuals in western Kenya. Included in this analysis were adolescents aged 10-19 enrolled in AMPATH between January 2005 and February 2017. Socio-demographic, behavioural, and clinical data at baseline and time-updated antiretroviral treatment (ART) data were extracted from the electronic medical records and summarized using descriptive statistics. Follow up time was defined as time of inclusion in the cohort until the date of first pregnancy or age 20, loss to follow up, death, or administrative censoring. Adolescent pregnancy rates and associated risk factors were determined. RESULTS: There were 8565 adolescents eligible for analysis. Median age at enrolment in HIV care was 14.0 years. Only 17.7% had electricity at home and 14.4% had piped water, both indicators of a high level of poverty. 12.9% (1104) were pregnant at study inclusion. Of those not pregnant at enrolment, 5.6% (448) became pregnant at least once during follow-up. Another 1.0% (78) were pregnant at inclusion and became pregnant again during follow-up. The overall pregnancy incidence rate was 21.9 per 1000 woman years or 55.8 pregnancies per 1000 women. Between 2005 and 2017, pregnancy rates have decreased. Adolescents who became pregnant in follow-up were more likely to be older, to be married or living with a partner and to have at least one child already and less likely to be using family planning. CONCLUSIONS: A considerable number of these HIV-positive adolescents presented at enrolment into HIV care as pregnant and many became pregnant as adolescents during follow-up. Pregnancy rates remain high but have decreased from 2005 to 2017. Adolescent-focused sexual and reproductive health and ante/postnatal care programs may have the potential to improve maternal and neonatal outcomes as well as further decrease pregnancy rates in this high-risk group.

OBJECTIVE: To obtain an estimate of the size of, and human immunodeficiency (HIV) prevalence among, young people and children living on the streets of Eldoret, Kenya. METHODS: We counted young people and children using a point-in-time approach, ensuring we reached our target population by engaging relevant community leaders during the planning of the study. We acquired point-in-time count data over a period of 1 week between the hours of 08:00 and 23:00, from both a stationary site and by mobile teams. Participants provided demographic data and a fingerprint (to avoid double-counting) and were encouraged to speak with an HIV counsellor and undergo HIV testing. We used a logistic regression model to test for an association between age or sex and uptake of HIV testing and seropositivity. FINDINGS: Of the 1419 eligible participants counted, 1049 (73.9%) were male with a median age of 18 years. Of the 1029 who spoke with a counsellor, 1004 individuals accepted HIV counselling and 947 agreed to undergo an HIV test. Combining those who were already aware of their HIV-positive status with those who were tested during our study resulted in an overall HIV seroprevalence of 4.1%. The seroprevalence was 2.7% (19/698) for males and 8.9% (23/259) for females. We observed an increase in seroprevalence with increasing age for both sexes, but of much greater magnitude for females. CONCLUSION: By counting young people and children living on the streets and offering them HIV counselling and testing, we could obtain population-based estimates of HIV prevalence.

The disproportionate burden of HIV among women in sub-Saharan Africa reflects underlying gender inequities, which also impact patient-provider relationships, a key component to retention in HIV care. This study explored how gender shaped the patient-provider relationship and consequently, retention in HIV care in western Kenya. We recruited and consented 60 HIV care providers from three facilities in western Kenya affiliated with the Academic Model Providing Access to Healthcare (AMPATH). Trained research assistants conducted and audio recorded 1-h interviews in English or Swahili. Data were transcribed and analyzed in NVivo using inductive thematic analysis. Gender constructs, as culturally defined, emerged as an important barrier negatively impacting the patient-provider relationship through three main domains: (1) challenges establishing clear roles and sharing power due to conflicting gender versus patient/provider identities, (2) provider frustration over suboptimal patient adherence resulting from gender-influenced contextual barriers, and (3) negative provider perceptions shaped by differing male and female approaches to communication. Programmatic components addressing gender inequities in the health care setting are urgently needed to effectively leverage the patient-provider relationship and fully promote long-term adherence and retention in HIV care.

Research suggests a burden of HIV among street-connected youth (SCY) in Kenya. We piloted the use of peer navigators (PNs), individuals of mixed HIV serostatus and with direct experience of being street-connected, to link SCY to HIV testing and care. From January 2015 to October 2017, PNs engaged 781 SCY (585 male, 196 female), median age 16 (IQR 13-20). At initial encounter, 52 (6.6%) were known HIV-positive and 647 (88.8%) agreed to HIV testing. Overall, 63/781 (8.1%) SCY engaged in this program were HIV-positive; 4.6% males and 18.4% females (p < 0.001). Of those HIV-positive, 48 (82.8%) initiated ART. As of October 2017, 35 (60.3%) of the HIV-positive SCY were alive and in care. The pilot suggests that PNs were successful in promoting HIV testing, linkage to care and ART initiation. More research is needed to evaluate how to improve ART adherence, viral suppression and retention in care in this population.

The human immunodeficiency virus (HIV) care cascade is a conceptual model used to outline the benchmarks that reflects effectiveness of HIV care in the whole HIV care continuum. The models can be used to identify barriers contributing to poor outcomes along each benchmark in the cascade such as disengagement from care or death. Recently, the HIV care cascade has been widely applied to monitor progress towards HIV prevention and care goals in an attempt to develop strategies to improve health outcomes along the care continuum. Yet, there are challenges in quantifying successes and gaps in HIV care using the cascade models that are partly due to the lack of analytic approaches. The availability of large cohort data presents an opportunity to develop a coherent statistical framework for analysis of the HIV care cascade. Motivated by data from the Academic Model Providing Access to Healthcare, which has provided HIV care to nearly 200,000 individuals in Western Kenya since 2001, we developed a state transition framework that can characterize patient-level movements through the multiple stages of the HIV care cascade. We describe how to transform large observational data into an analyzable format. We then illustrate the state transition framework via multistate modeling to quantify dynamics in retention aspects of care. The proposed modeling approach identifies the transition probabilities of moving through each stage in the care cascade. In addition, this approach allows regression-based estimation to characterize effects of (time-varying) predictors of within and between state transitions such as retention, disengagement, re-entry into care, transfer-out, and mortality.
