RESUMEN
BACKGROUND: There is mixed evidence on the influence of self-disclosure of one's HIV status on mental health, health behaviours and clinical outcomes. We studied the patterns of self-disclosure among parents living with HIV, and factors that influence parental disclosure. METHODS: This mixed-methods study was among adults in HIV care participating in a study assessing the uptake of pediatric index-case testing. They completed a survey to provide demographic and HIV-related health information, and assess self-disclosure to partners, children and others. We ran generalized linear models to determine factors associated with disclosure and reported prevalence ratios (PR). Eighteen participants also participated in in-depth interviews to explore perceived barriers and facilitators of self-disclosure to one's child. A content analysis approach was used to analyze interview transcripts. RESULTS: Of 493 caregivers, 238 (48%) had a child ≥ 6 years old who could potentially be disclosed to about their parent's HIV status. Of 238 participants, 205 (86%) were female, median age was 35 years, and 132 (55%) were in a stable relationship. Among those in a stable relationship, 96 (73%) knew their partner's HIV status, with 79 (60%) reporting that their partner was living with HIV. Caregivers had known their HIV status for a median 2 years, and the median age of their oldest child was 11 years old. Older caregiver age and older first born child's age were each associated with 10% higher likelihood of having disclosed to a child (PR: 1.10 [1.06-1.13] and PR: 1.10 [1.06-1.15], per year of age, respectively). The child's age or perceived maturity and fear of causing anxiety to the child inhibited disclosure. Child's sexual activity was a motivator for disclosure, as well as the belief that disclosing was the "right thing to do". Caregivers advocated for peer and counseling support to gain insight on appropriate ways to disclose their status. CONCLUSIONS: Child's age is a key consideration for parents to disclose their own HIV status to their children. While parents were open to disclosing their HIV status to their children, there is a need to address barriers including anticipated stigma, and fear that disclosure will cause distress to their children.

Expanding index and family-based testing (HBT) is a priority for identifying children living with HIV. Our study characterizes predictors that drive testing location choice for children of parents living with HIV. Kenyan adults living with HIV were offered a choice of HBT or clinic-based testing (CBT) for any of their children (0-12 years) of unknown HIV status. Multilevel generalized linear models were used to identify correlates of choosing HBT or CBT for children and testing all versus some children within a family, including caregiver demographics, HIV history, social support, cost, and child demographics and HIV prevention history. Among 244 caregivers living with HIV and their children of unknown HIV status, most (72%) caregivers tested children using CBT. In multivariate analysis, female caregivers [aRR 0.52 (95% CI 0.34-0.80)] were less likely to choose HBT than male caregivers. Caregivers with more children requiring testing [aRR 1.23 (95% CI 1.05-1.44)] were more likely to choose HBT than those with fewer children requiring testing. In subgroup univariate analysis, female caregivers with a known HIV negative spouse were significantly more likely to choose HBT over CBT than those with a known HIV positive spouse [RR 2.57 (95% CI 1.28-5.14), p = 0.008], no association was found for male caregivers. Child demographics and clinical history was not associated with study outcomes. Caregiver-specific factors were more influential than child-specific factors in caregiver choice of pediatric HIV testing location. Home-based testing may be preferable to families with higher child care needs and may encourage pediatric HIV testing if offered as an alternative to clinic testing.

Video-based pre-test information is used in high resource settings to increase HIV testing coverage but remains untested in resource-limited settings. We conducted formative and evaluative focus group discussions with healthcare workers (HCWs) and caregivers of children in Kenya to develop and refine a pediatric HIV pre-test informational video. We then assessed HIV knowledge among caregivers sequentially enrolled in one of three pre-test information groups: (1) individual HCW-led (N = 50), (2) individual video-based (N = 50), and (3) group video-based (N = 50) sessions. A brief video incorporating information on national pediatric testing, modes of HIV transmission, and dramatized testimonials of caregivers who tested children was produced in three languages. Compared to individual HCW-led sessions (mean: 7.2/9; standard deviation [SD]: 1.3), both the group video-based (mean: 7.7; SD: 0.9) and individual video-based (mean: 7.6; SD: 0.9) sessions had higher mean knowledge scores. Video-based pre-test information could enhance existing pediatric HIV testing services.

Identifying determinants of human immunodeficiency virus (HIV) reservoir levels may inform novel viral eradication strategies. Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) coinfections were assessed as predictors of HIV proviral DNA level in 26 HIV RNA-suppressed Kenyan children starting antiretroviral therapy before 7 months of age. Earlier acquisition of CMV and EBV and higher cumulative burden of systemic EBV DNA viremia were each associated with higher HIV DNA level in the reservoir after 24 months of antiretroviral therapy, independent of HIV RNA levels over time. These data suggest that delaying or containing CMV and EBV viremia may be novel strategies to limit HIV reservoir formation.

Children living with HIV experience gaps in HIV testing globally; scaling up evidence-based testing strategies is critical for preventing HIV-related mortality. Financial incentives (FI) were recently demonstrated to increase uptake of pediatric HIV testing. As part of this qualitative follow-up study to the FIT trial (NCT03049917) conducted in Kenya, 54 caregivers participated in individual interviews. Interview transcripts were analyzed to identify considerations for scaling up FI for pediatric testing. Caregivers reported that FI function by directly offsetting costs or nudging caregivers to take action sooner. Caregivers found FI to be feasible and acceptable for broader programmatic implementation, and supported use for a variety of populations. Some concerns were raised about unintended consequences of FI, including caregivers bringing ineligible children to collect incentives and fears about the impact on linkage to care and retention if caregivers become dependent on FI.

BACKGROUND: Few oral health studies have been conducted in HIV-exposed uninfected children, who, like their HIV-infected peers, have altered immunity and perinatal drug exposures. AIM: To compare caregiver' self-report of oral diseases, hygiene practices and utilization of routine dental care, between HIV-infected (HIV), HIV-exposed uninfected (HEU), and HIV-unexposed uninfected (HUU) children in Kenya. DESIGN: This nested cross-sectional study was conducted at the Kenyatta National Hospital, Nairobi, Kenya. Caregivers of 196 children (104 HIV-infected, 55 HEU, and 37 HUU) participated in this study. Using a validated questionnaire from the WHO and photographs of HIV-related oral lesions, we collected data on oral diseases and oral health practices. RESULTS: Caregivers of HIV-infected children reported at least one oral disease in their children (42%; HEU [27%]; HUU [17%; P = .008]). Oral candidiasis was the most common disease reported (HIV-infected [24%], HEU [5.5%], and HUU [2.8%; P < .05]). Baseline CD4% was associated with oral candidiasis (OR = 0.93, 95% CI: 0.88-0.98). Only 16% of children had ever visited a dentist, and most initiated brushing after 3 years of age (83%). Nearly all (98%) caregivers desired a follow-up oral examination. CONCLUSIONS: HIV infection/exposure and low CD4% were associated with increased odds of oral diseases. Most caregivers desired a follow-up oral examination for their children.

HIV incidence and mortality are high among adolescents and young adults (AYA) in sub-Saharan Africa, but testing rates are low. Understanding how support people (SP), such as peers, partners, or parents, influence AYA may improve HIV testing uptake. AYA aged 14-24 seeking HIV testing at a referral hospital in Nairobi, Kenya completed a post-test survey assessing the role of SP. Among 1062 AYA, median age was 21. Overall, 12% reported their decision to test was influenced by a parent, 20% by a partner, and 22% by a peer. Young adults (20-24 years old) were more likely than adolescents (14-19 years old) to be influenced to test by partners (23% vs. 12%, p < .001), and less likely by parents (6.6% vs. 27%, p < .001), healthcare workers (11% vs. 16%, p < .05), or counselors (9.4% vs. 19%, p < .001). Half of AYA were accompanied for testing (9.9% with parent, 10% partner, 23% peer, 4.3% others, and 2.1% multiple types). Young adults were more likely than adolescents to present alone (58% vs. 32%, p < .001) or with a partner (12% vs. 6.7%, p < .05), and less likely with a parent (1.6% vs. 31%, p < .001). Similar proportions of adolescents and young adults came with a peer or in a group. Correlates of presenting with SP included: younger age (aRR = 1.55 [95%CI = 1.30-1.85]), female sex (aRR = 1.45 [95%CI = 1.21-1.73]), and school enrollment (aRR = 1.41 [95%CI = 1.05-1.88]). SP play an important role in AYAs' HIV testing and varies with age. Leveraging SP may promote uptake of HIV testing and subsequent linkage care for AYA.

BACKGROUND: Cytomegalovirus (CMV) is associated with morbidity and mortality in human immunodeficiency virus (HIV)-exposed infants. We assessed the effect of and relative contribution of breastfeeding to CMV acquisition among infants delivered by HIV-infected mothers. METHODS: Between 1993 and 1998 pregnant, HIV-infected women in Nairobi, Kenya, were randomly assigned to breastfeed or formula-feed their infants in an HIV transmission study. Women were allocated equally between treatment arms, and the study was not blinded. The primary endpoint of this nested study was time to infant CMV infection. RESULTS: CMV infection was assessed in 138 breastfed and 134 formula-fed infants. Baseline characteristics were similar between arms. Breastfed infants acquired CMV earlier than formula-fed infants (median age of acquisition, 4.26 vs 9.87 months; P < .001) and had a higher 1-year probability of CMV infection (0.89 vs 0.69; P < .001). Breastfeeding was associated with a 1.6-fold increased risk of infant CMV acquisition independent of infant HIV status (multivariable hazard ratio, 1.61; 95% confidence interval, 1.20-2.16; P = .002). Approximately one third of CMV infections occurred during the peripartum period, with 40% acquired through breastfeeding and the remainder acquired through modes other than breast milk. CONCLUSIONS: Preventing CMV acquisition may be a priority for HIV-exposed infants, but there is a narrow window of opportunity for intervention. Approaches that reduce maternal cervical and breast milk CMV reactivation may help delay infant infection.

We compared primary Epstein-Barr virus (EBV) infection and suppression between Kenyan human immunodeficiency virus-infected infants starting nevirapine-based vs lopinavir/ritonavir-based antiretroviral regimens. Although the rate of EBV infection was similar between groups, infants receiving lopinavir/ritonavir suppressed EBV more rapidly. Our findings suggest that specific antiretrovirals may potentially impact the risk of future EBV-associated malignancies.

Effective biomedical and structural HIV prevention approaches are being implemented throughout sub-Saharan Africa. A "lifecycle approach" to HIV prevention recognizes the interconnectedness of the health of women, children and adolescents, and prioritizes interventions that have benefits across these populations. We review new biomedical prevention strategies for women, adolescents and children, structural prevention approaches, and new modalities for eliminating infant HIV infection, and discuss the implications of a lifecycle approach for the success of these methods. Some examples of the lifecycle approach include evaluating education and HIV prevention strategies among adolescent girls not only for their role in reducing risk of HIV infection and early pregnancy, but also to promote healthy adolescents who will have healthier future children. Similarly, early childhood interventions such as exclusive breastfeeding not only prevent HIV, but also contribute to better child and adolescent health outcomes. The most ambitious biomedical infant HIV prevention effort, Option B+, also represents a lifecycle approach by leveraging the prevention benefits of optimal HIV treatment for mothers; maternal survival benefits from Option B+ may have ultimately more health impact on children than the prevention of infant HIV in isolation. The potential for synergistic and additive benefits of lifecycle interventions should be considered when scaling up HIV prevention efforts in sub-Saharan Africa.

BACKGROUND: Preterm birth (PTB), low birth weight (LBW) and small for gestational age (SGA) contribute to neonatal mortality. Maternal HIV-1 infection has been associated with an increased risk of PTB, but mechanisms underlying this association are undefined. We describe correlates and outcomes of PTB, LBW, and SGA in HIV-exposed uninfected infants. METHODS: This was a retrospective analysis of cohort study. Between 1999-2002, pregnant, HIV-infected women were enrolled into an HIV-1 transmission study. Logistic regression was used to identify correlates of PTB, LBW and SGA in HIV-negative, spontaneous singleton deliveries. Associations between birth outcomes and mortality were measured using survival analyses. RESULTS: In multivariable models, maternal plasma (OR = 2.1, 95% CI = 1.1-3.8) and cervical HIV-1 RNA levels (OR = 1.6, 95% CI = 1.1-2.4), and CD4 < 15% (OR = 2.4, 95% CI = 1.0-5.6) were associated with increased odds of PTB. Abnormal vaginal discharge and cervical polymorphonuclear leukocytes were also associated with PTB. Cervical HIV-1 RNA level (OR = 2.4, 95% CI = 1.5-6.7) was associated with an increased odds of LBW, while increasing parity (OR = 0.46, 95% CI = 0.24-0.88) was associated with reduced odds. Higher maternal body mass index (OR = 0.75, 95% CI = 0.61-0.92) was associated with a reduced odds of SGA, while bacterial vaginosis was associated with >3-fold increased odds (OR = 3.2, 95% CI = 1.4-7.4). PTB, LBW, and SGA were each associated with a >6-fold increased risk of neonatal death, and a >2-fold increased rate of infant mortality within the first year. CONCLUSIONS: Maternal plasma and cervical HIV-1 RNA load, and genital infections may be important risk factors for PTB in HIV-exposed uninfected infants. PTB, LBW, and SGA are associated with increased neonatal and infant mortality in HIV-exposed uninfected infants.

BACKGROUND: Human immunodeficiency virus (HIV) infection is a risk factor for Epstein-Barr virus (EBV)-associated lymphomas. Characterizing primary infection may elucidate risk factors for malignancy. METHODS: To describe clinical and virologic manifestations of primary EBV infection among infants born to HIV-infected women, specimens were utilized from a cohort study conducted in Nairobi, Kenya. HIV and EBV viral loads were measured serially in plasma. EBV serology was performed on EBV DNA-negative infants. Monthly clinical examinations were performed by pediatricians. RESULTS: The probability of EBV infection by 1 year of age was .78 (95% CI, .67-.88) in HIV-infected and .49 (95% CI, .35-.65) in HIV-uninfected infants (P < .0001). At 2 years, probability of EBV infection was .96 (95% CI, .89-.99) in HIV-infected infants. Peak EBV loads were higher in HIV-infected versus HIV-uninfected infants (median 2.6 vs 2.1 log10 copies/mL; P < .0001). The majority of HIV-infected infants had detectable EBV DNA for >3 months (79%). Primary EBV infection was associated with cough, fever, otitis media, pneumonia, hepatomegaly, splenomegaly, and hospitalization in HIV-infected infants; conjunctivitis and rhinorrhea in HIV-uninfected infants. CONCLUSIONS: EBV infection occurs early in infants born to HIV-infected women. HIV infection was associated with more frequent and higher quantity EBV DNA detection.

Introduction: Human cathelicidin LL-37 is a salivary antimicrobial peptide (AMP) with broad-spectrum activity against oral diseases, but few studies have assessed its role in children and adolescents living with HIV (CALHIV). We assessed salivary LL-37 levels and correlates in a long-term cohort of Kenyan CALHIV followed since antiretroviral therapy (ART) initiation. Methods: Saliva was collected from 76 CALHIV who were recruited from two ongoing pediatric HIV studies in Nairobi, Kenya. Oral examinations documenting oral manifestations of HIV, dental caries, and gingivitis were completed. Additional variables included age, sex, HIV treatment (initial ART regimen) and disease parameters, caregivers' demographics, and oral pathologies were conducted. Data were statistically analyzed using the independent T test on the log-transformed LL-37. Results: At the oral exam visit, the mean age of participants was 13.3 years (±SD = 3.4), and the median CD4 count was 954 cells/mm3. Mean salivary cathelicidin values of the cohort were 23.7 ± 21.1 ng/mL. Children with permanent dentition at time of oral examination, and children who initiated ART at ≥2 years old had higher mean LL-37 concentrations compared to those with mixed dentition and those who initiated ART <2 years old (p = 0.0042, 0.0373, respectively). LL-37 levels were not found to differ by initial type of ART regimen, CD4 count, or oral disease. Conclusion: Further research and longitudinal studies are necessary to evaluate and improve the innate immunity of CALHIV in Kenya.
RESUMEN
Cytomegalovirus (CMV) coinfection is associated with infant HIV-1 disease progression and mortality. In a cohort of Kenyan HIV-infected infants, the frequencies of activated (CD38(+) HLA-DR(+)) and apoptosis-vulnerable (CD95(+) Bcl-2(-)) CD4(+) and CD8(+) T cells increased substantially during acute CMV infection. The frequency of activated CD4(+) T cells was strongly associated with both concurrent CMV coinfection (P = 0.001) and HIV-1 viral load (P = 0.05). The frequency of apoptosis-vulnerable cells was also associated with CMV coinfection in the CD4 (P = 0.02) and CD8 (P < 0.001) T cell subsets. Similar observations were made in HIV-exposed uninfected infants. CMV-induced increases in T cell activation and apoptosis may contribute to the rapid disease progression in coinfected infants.

OBJECTIVE: We determined predictors of both intact (estimate of replication-competent) and total (intact and defective) HIV DNA in the reservoir among children with HIV. DESIGN: HIV DNA in the reservoir was quantified longitudinally in children who initiated antiretroviral therapy (ART) at less than 1âyear of age using a novel cross-subtype intact proviral DNA assay that measures both intact and total proviruses. Quantitative PCR was used to measure pre-ART cytomegalovirus (CMV) viral load. Linear mixed effects models were used to determine predictors of intact and total HIV DNA levels (log 10 copies/million). RESULTS: Among 65 children, median age at ART initiation was 5âmonths and median follow-up was 5.2âyears; 86% of children had CMV viremia pre-ART. Lower pre-ART CD4 + percentage [adjusted relative risk (aRR): 0.87, 95% confidence intervals (95% CI): 0.79-0.97; P â=â0.009] and higher HIV RNA (aRR: 1.21, 95% CI: 1.06-1.39; P â=â0.004) predicted higher levels of total HIV DNA during ART. Pre-ART CD4 + percentage (aRR: 0.76, 95% CI: 0.65-0.89; P < 0.001), CMV viral load (aRR: 1.16, 95% CI: 1.01-1.34; P â=â0.041), and first-line protease inhibitor-based regimens compared with nonnucleoside reverse transcriptase-based regimens (aRR: 1.36, 95% CI: 1.04-1.77; P â=â0.025) predicted higher levels of intact HIV DNA. CONCLUSION: Pre-ART immunosuppression, first-line ART regimen, and CMV viral load may influence establishment and sustainment of intact HIV DNA in the reservoir.

OBJECTIVES: The impact of antiretroviral treatment (ART) on the occurrence of oral diseases among children and adolescents living with HIV (CALHIV) is poorly understood. The aim of this study was to determine the effect of ART timing on vitamin D levels and the prevalence of four oral diseases (dry mouth, dental caries, enamel hypoplasia, and non-herpes oral ulcer) among Kenyan CALHIV from two pediatric HIV cohorts. METHODS: This nested cross-sectional study was conducted at the Kenyatta National Hospital, Nairobi, Kenya. CALHIV, 51 with early-ART initiated at <12 months of age and 27 with late-ART initiated between 18 months-12 years of age, were included. Demographics, HIV diagnosis, baseline CD4 and HIV RNA viral load data were extracted from the primary study databases. Community Oral Health Officers performed oral health examinations following standardized training. RESULTS: Among 78 CALHIV in the study, median age at the time of the oral examination was 11.4 years old and median ART duration at the time of oral examination was 11 years (IQR: 10.1, 13.4). Mean serum vitamin D level was significantly higher among the early-ART group than the late-ART group (29.5 versus 22.4 ng/mL, p = 0.0002). Children who received early-ART had a 70% reduction in risk of inadequate vitamin D level (<20 ng/mL), compared to those who received late-ART (p = 0.02). Although both groups had similar prevalence of oral diseases overall (early-ART 82.4%; late-ART 85.2%; p = 0.2), there was a trend for higher prevalence of dry mouth (p = 0.1) and dental caries (p = 0.1) in the early versus late ART groups. The prevalence of the four oral diseases was not associated with vitamin D levels (p = 0.583). CONCLUSIONS: After >10 years of ART, CALHIV with early-ART initiation had higher serum vitamin D levels compared to the late-ART group. The four oral diseases were not significantly associated with timing of ART initiation or serum vitamin D concentrations in this cohort. There was a trend for higher prevalence of dry mouth and dental caries in the early-ART group, probably as side-effects of ART.

BACKGROUND: Pediatric HIV testing remains suboptimal. The OraQuick test [saliva-based test (SBT)] is validated in pediatric populations ≥18 months. Understanding caregiver and health care worker (HCW) acceptability of pediatric SBT is critical for implementation. METHODS: A trained qualitative interviewer conducted 8 focus group discussions (FGDs): 4 with HCWs and 4 with caregivers of children seeking health services in western Kenya. FGDs explored acceptability of pediatric SBT and home- and facility-based SBT use. Two reviewers conducted consensus coding and thematic analyses of transcripts using Dedoose. RESULTS: Most HCWs but few caregivers had heard of SBT. Before seeing SBT instructions, both had concerns about potential HIV transmission through saliva, which were mostly alleviated after kit demonstration. Noted benefits of SBT included usability and avoiding finger pricks. Benefits of facility-based pediatric SBT included shorter client waiting and service time, higher testing coverage, and access to HCWs, while noted challenges included ensuring confidentiality. Benefits of caregivers using home-based SBT included convenience, privacy, decreased travel costs, increased testing, easier administration, and child comfort. Perceived challenges included not receiving counseling, disagreements with partners, child neglect, and negative emotional response to a positive test result. Overall, HCWs felt that SBT could be used for pediatric HIV testing but saw limited utility for caregivers performing SBT without an HCW present. Caregivers saw utility in home-based SBT but wanted easy access to counseling in case of a positive test result. CONCLUSIONS: SBT was generally acceptable to HCWs and caregivers and is a promising strategy to expand testing coverage.

Lack of health care worker (HCW) training is a barrier to implementing youth-friendly services. We examined training coverage and self-reported competence, defined as knowledge, abilities, and attitudes, of HCWs caring for adolescents living with HIV (ALWH) in Kenya. Surveys were conducted with 24 managers and 142 HCWs. Competence measures were guided by expert input and Kalamazoo II Consensus items. Health care workers had a median of 3 (interquartile range [IQR]: 1-6) years of experience working with ALWH, and 40.1% reported exposure to any ALWH training. Median overall competence was 78.1% (IQR: 68.8-84.4). In multivariable linear regression analyses, more years caring for ALWH and any prior training in adolescent HIV care were associated with significantly higher self-rated competence. Training coverage for adolescent HIV care remains suboptimal. Targeting HCWs with less work experience and training exposure may be a useful and efficient approach to improve quality of youth-friendly HIV services.

INTRODUCTION: Gaps in HIV testing of children persist, particularly among older children born before the expansion of the prevention of mother-to-child transmission of HIV programs. METHODS: The Counseling and Testing for Children at Home study evaluated an index-case pediatric HIV testing approach. Caregivers receiving HIV care at 7 health facilities in Kenya (index cases), who had children of unknown HIV status aged 0-12 years, were offered the choice of clinic-based testing (CBT) or home-based testing (HBT). Testing uptake and HIV prevalence were compared between groups choosing HBT and CBT; linkage to care, missed opportunities, and predictors of HIV-positive diagnosis were identified. RESULTS: Among 493 caregivers, 70% completed HIV testing for ≥1 child. Most caregivers who tested children chose CBT (266/347, 77%), with 103 (30%) agreeing to same-day testing of an untested accompanying child. Overall HIV prevalence among 521 tested children was 5.8% (CBT 6.8% vs HBT 2.4%; P = 0.07). Within 1 month of diagnosis, 88% of 30 HIV-positive children had linked to care, and 54% had started antiretroviral treatment. For 851 children eligible for testing, the most common reason for having an unknown HIV status was that the child's mother was not tested for HIV or had tested HIV negative during pregnancy (82%). CONCLUSION: Testing uptake and HIV prevalence were moderate with nonsignificant differences between HBT and CBT. Standardized offer to test children accompanying caregivers is feasible to scale-up with little additional investment. Linkage to care for HIV-positive children was suboptimal. Lack of peripartum maternal testing contributed to gaps in pediatric testing.

BACKGROUND: A prior randomized control trial showed financial incentives increase HIV testing rates for children of unknown HIV status. Translating evidence-based interventions such as these to scale requires an implementation science approach. METHODS: A qualitative study evaluating health care providers' perceptions of barriers and facilitators of a previously completed financial incentives intervention for pediatric HIV testing was conducted at health care facilities in Kisumu, Kenya. Six focus group discussions with 52 providers explored determinants of acceptability, feasibility, and sustainability of financial incentive scale-up for pediatric HIV testing using the Consolidated Framework for Implementation Research to inform question guides and thematic analysis. RESULTS: Providers found the use of financial incentive interventions for pediatric HIV testing to be highly acceptable. First, providers believed financial incentives had a relative advantage over existing strategies, because they overcame cost barriers and provided additional motivation to test; however, concerns about how financial incentives would be implemented influenced perceptions of feasibility and sustainability. Second, providers expressed concern that already overburdened staff and high costs of financial incentive programs would limit sustainability. Third, providers feared that financial incentives may negatively affect further care because of expectations of repeated financial support and program manipulation. CONCLUSIONS: Providers viewed financial incentives as an acceptable intervention to scale programmatically to increase uptake of pediatric testing. To ensure feasibility and sustainability of financial incentives in pediatric HIV testing programs, it will be important to clearly define target populations, manage expectations of continued financial support, and establish systems to track testing.
