Project description:OBJECTIVE:We sought to evaluate whether HIV-positive adults in Malawi were willing to distribute HIV self-testing (HIVST) kits to their sexual partners of unknown HIV status (index HIVST). DESIGN:A mixed-methods study was nested within a larger HIVST trial conducted at 15 health facilities in Malawi. Exit surveys were conducted with HIV-positive adults during routine outpatient department visits to assess perceived acceptability of index partner HIVST versus standard partner referral slips that request partner(s) to attend the health facility. Individuals were included in the sub-analysis irrespective of date of HIV diagnosis or ART initiation (or non-initiation). In-depth interviews were conducted with a sub-sample of respondents. RESULTS:404 HIV-positive adults completed a survey (159 male and 245 female); 21 completed in-depth interviews. Respondents reported feeling more comfortable distributing HIVST versus partner referral slips to their partners (90% vs. 81%) and expressed confidence that their partners would test using HIVST compared to referral slips (77% vs. 66%). Acceptability of HIVST did not vary by sex. Qualitative data revealed that index HIVST was perceived to be private, convenient, and may strengthen relationships by assisting in serostatus disclosure. There were minimal fears of adverse events. Reported barriers to index HIVST included lack of trust within the relationship and harmful gender norms. CONCLUSIONS:HIV-positive clients were willing to distribute HIVST kits to their sexual partners of unknown serostatus. Additional studies are needed to evaluate use of HIVST by index partners, positivity, linkage to care, and adverse events related to index partner HIVST, such as coercion to test among index partners or interpersonal violence among index clients.

Project description:PURPOSE OF REVIEW:We reviewed recent literature on conditional and unconditional financial incentives for their impact on improving movement through the HIV care cascade and HIV prevention. RECENT FINDINGS:Concepts from behavioral economics may help improve engagement in HIV care by addressing upstream structural risk factors for HIV, such as poverty, or providing conditional rewards for immediate, measurable outcomes related to HIV care. Incentives have been shown to increase uptake of HIV testing. Yet, few studies to date focus on linkage to care: one large USA-based randomized trial failed to show an effect of incentives; and a smaller trial showed improved linkage to care among drug users, but no difference in virologic suppression. Several small USA-based studies have shown an impact of financial incentives on antiretroviral therapy adherence, but without durability beyond the incentive period. HIV prevention has the most robust evidence for decreasing HIV risk-taking behavior among adolescents and may serve as a model for research on the care cascade. SUMMARY:Financial incentives show promise for improving engagement in HIV testing, care, and prevention. Understanding the durability, scalability, ease of implementation, and cost-effectiveness of these different approaches will be critical for maximizing the impact of incentives in curtailing the HIV epidemic.

Project description:BackgroundFinancial incentives can motivate desirable health behaviors, including adult HIV testing. Data regarding the effectiveness of financial incentives for HIV testing in children, who require urgent testing to prevent mortality, are lacking.MethodsIn a five-arm unblinded randomized controlled trial, adults living with HIV attending 19 HIV clinics in Western Kenya, with children 0-12 years of unknown HIV status, were randomized with equal allocation to $0, $1.25, $2.50, $5 or $10. Payment was conditional on child HIV testing within 2 months. Block randomization with fixed block sizes was used; participants and study staff were unblinded at randomization. Primary analysis was intent-to-treat, with predefined primary outcomes of completing child HIV testing and time to testing.ResultsOf 452 caregivers, 90, 89, 93, 92 and 88 were randomized to $0, $1.25, $2.50, $5.00, and $10.00, respectively. Of those, 31 (34%), 31 (35%), 44 (47%), 51 (55%), and 54 (61%) in the $0, $1.25, $2.50, $5.00, and $10.00 arms, respectively, completed child testing. Compared with the $0 arm, and adjusted for site, caregivers in the $10.00 arm had significantly higher uptake of testing [relative risk: 1.80 (95% CI 1.15--2.80), P = 0.010]. Compared with the $0 arm, and adjusted for site, time to testing was significantly faster in the $5.00 and $10.00 arms [hazard ratio: 1.95 (95% CI 1.24--3.07) P = 0.004, 2.42 (95% CI 1.55--3.79), P < 0.001, respectively).ConclusionFinancial incentives are effective in improving pediatric HIV testing among caregivers living with HIV.RegistrationNCT03049917.

Project description:BackgroundFinancial incentives promote use of HIV services and might support adherence to the sustained antiretroviral therapy (ART) necessary for viral suppression, but few studies have assessed a biomarker of adherence or evaluated optimal implementation. We sought to determine whether varying sized financial incentives for clinic attendance effected viral suppression in patients starting ART in Tanzania.MethodsIn a three-arm, parallel-group, randomised controlled trial at four health facilities in Shinyanga region, Tanzania, adults aged 18 years or older with HIV who had started ART within the past 30 days were randomly assigned (1:1:1) using a tablet-based application (stratified by site) to receive usual care (control group) or to receive a cash incentive for monthly clinic attendance in one of two amounts: 10 000 Tanzanian Shillings (TZS; about US$4·50) or 22 500 TZS (about $10·00). There were no formal exclusion criteria. Participants were masked to the existence of two incentive sizes. Incentives were provided for up to 6 months via mobile health technology (mHealth) that linked biometric attendance monitoring to automated mobile payments. We evaluated the primary outcome of retention in care with viral suppression (<1000 copies per mL) at 6 months using logistic regression. This trial is registered with ClinicalTrials.gov, NCT03351556.FindingsBetween April 24 and Dec 14, 2018, 530 participants were randomly assigned to an incentive strategy (184 in the control group, 172 in the smaller incentive group, and 174 in the larger incentive group). All participants were included in the primary intention-to-treat analysis. At 6 months, approximately 134 (73%) participants in the control group remained in care and had viral suppression, compared with 143 (83%) in the smaller incentive group (risk difference [RD] 9·8, 95% CI 1·2 to 18·5) and 150 (86%) in the larger incentive group (RD 13·0, 4·5 to 21·5); we identified a positive trend between incentive size and viral suppression (p trend=0·0032), although the incentive groups did not significantly differ (RD 3·2, -4·6 to 11·0). Adverse events included seven (4%) deaths in the control group and 11 (3%) deaths in the intervention groups, none related to study participation.InterpretationSmall financial incentives delivered using mHealth can improve retention in care and viral suppression in adults starting HIV treatment. Although further research should investigate the durability of effects from short-term incentives, these findings strengthen the evidence for implementing financial incentives within standard HIV care.FundingNational Institute of Mental Health at the US National Institutes of Health.

Project description:BackgroundFinancial incentives are an effective way of helping women to stop smoking during pregnancy. Unfortunately, most women who stop smoking at this time return to smoking within 12 months of the infant's birth. There is no evidence for interventions that are effective at preventing postpartum smoking relapse. Financial incentives provided after the birth may help women to sustain cessation. This randomised controlled trial will assess the effectiveness and cost-effectiveness of financial incentives to help women who are abstinent from smoking at end-of-pregnancy to avoid return to smoking up to 12 months postpartum.MethodsThis is a UK-based, multi-centre, three-arm, superiority, parallel group, individually randomised controlled trial, with 1:1:1 allocation. It will compare the effectiveness of two financial incentive interventions with each other (one intervention for up to 3 months postpartum offering up to £120 of incentives (£60 for the participant and £60 for a significant other support); the other for up to 12 months postpartum with up to £300 of incentives (£240 for the participant and £60 for a significant other support) and with a no incentives/usual care control group. Eligible women will be between 34 weeks gestation and 2 weeks postpartum, abstinent from smoking for at least 4 weeks, have an expired carbon monoxide (CO) reading < 4 parts per million (ppm), aged at least 16 years, intend remaining abstinent from smoking after the birth and able to speak and read English. The primary outcome is self-reported, lapse-free, smoking abstinence from the last quit attempt in pregnancy until 12 months postpartum, biochemically validated by expired CO and/or salivary cotinine or anabasine. Outcomes will be analysed by intention-to-treat and regression models used to compare the proportion of abstinent women between the two intervention groups and between each intervention group and the control group. An economic evaluation will assess the cost-effectiveness of offering incentives and a qualitative process evaluation will examine barriers and facilitators to trial retention, effectiveness and implementation.DiscussionThis pragmatic randomised controlled trial will test whether offering financial incentives is effective and cost-effective for helping women to avoid smoking relapse during the 12 months after the birth of their baby.Trial registrationInternational Standard Randomised Controlled Trial Number 55218215 .

Project description:INTRODUCTION:HIV self-testing (HIVST) provides couples and individuals with a discreet, convenient and empowering testing option. As with all HIV testing, potential harms must be anticipated and mitigated to optimize individual and public health benefits. Here, we describe social harms (SHs) reported during HIVST implementation in Malawi, and propose a framework for grading and responding to harms, according to their severity. METHODS:We report findings from six HIVST implementation studies in Malawi (2011 to 2017) that included substudies investigating SH reports. Qualitative methods included focus group discussions, in-depth interviews and critical incident interviews. Earlier studies used intensive quantitative methods (post-test questionnaires for intimate partner violence, household surveys, investigation of all deaths in HIVST communities). Later studies used post-marketing reporting with/without community engagement. Pharmacovigilance methodology (whereby potentially life-threatening/changing events are defined as "serious") was used to grade SH severity, assuming more complete passive reporting for serious events. RESULTS:During distribution of 175,683 HIVST kits, predominantly under passive SH reporting, 25 serious SHs were reported from 19 (0.011%) self-testers, including 15 partners in eight couples with newly identified HIV discordancy, and one perinatally infected adolescent. There were no deaths or suicides. Marriage break-up was the most commonly reported serious SH (sixteen individuals; eight couples), particularly among serodiscordant couples. Among new concordant HIV-positive couples, blame and frustration was common but rarely (one episode) led to serious SHs. Among concordant HIV-negative couples, increased trust and stronger relationships were reported. Coercion to test or disclose was generally considered "well-intentioned" within established couples. Women felt empowered and were assertive when offering HIVST test kits to their partners. Some women who persuaded their partner to test, however, did report SHs, including verbal or physical abuse and economic hardship. CONCLUSIONS:After more than six years of large-scale HIVST implementation and in-depth investigation of SHs in Malawi, we identified approximately one serious reported SH per 10,000 HIVST kits distributed, predominantly break-up of married serodiscordant couples. Both "active" and "passive" reporting systems identified serious SH events, although with more complete capture by "active" systems. As HIVST is scaled-up, efforts to support and further optimize community-led SH monitoring should be prioritized alongside HIVST distribution.

Project description:Access to safe drinking water and improved hygiene are important for reducing morbidity and mortality from diarrhea. We surveyed 330 pregnant women who participated in an antenatal clinic-based intervention in Malawi that promoted water treatment and hygiene through distribution of water storage containers, sodium hypochlorite water treatment solution, soap, and educational messages. Program participants were more likely to know correct water treatment procedures (62% versus 27%, P < 0.0001), chlorinate drinking water (61% versus 1%, P < 0.0001), demonstrate correct handwashing practices (68% versus 22%, P < 0.0001), and purchase water treatment solution after free distribution (32% versus 1%, P < 0.0001). Among participants, 72% had at least three antenatal visits, 76% delivered in a health facility, and 54% had a postnatal check. This antenatal-clinic-based program is an effective new strategy for promoting water treatment and hygiene behaviors among pregnant women. Participants had high use of antenatal, delivery, and postnatal services, which could improve maternal and child health.

Project description:OBJECTIVE:To test the effectiveness of financial incentives for smoking cessation in the Medicaid population. DATA SOURCES:Secondary data from the Medicaid Incentives for Prevention of Chronic Disease (MIPCD) program and Medicaid claims/encounter data from 2010 to 2015 for five states. STUDY DESIGN:Beneficiaries were randomized into receipt or no receipt of financial incentives. We ran multivariate regression models testing the impact of financial incentives on the use of counseling services, smoking behavior, and Medicaid expenditures and utilization. DATA EXTRACTION:Participating states provided Medicaid eligibility, claims and encounters, program enrollment, and incentivized service use data. PRINCIPAL FINDINGS:Participants who received incentives were more likely to call the Quitline and complete counseling sessions. Incentive receipt was positively associated with self-reported quit attempts, self-reported quits, or passing cotinine tests of smoking cessation in most programs, although results were only statistically significant in a subset. There was no systematic evidence that incentives affected health care use or spending. CONCLUSIONS:Financial incentives are a promising policy lever to motivate behavioral change in the Medicaid population, but more evidence is needed regarding optimal incentive size, effectiveness of process-versus outcome-based incentives, targeting of incentives, and long-run cost-effectiveness.

Project description:Depression among pregnant women living with HIV (WLWH) in sub-Saharan Africa leads to poor pregnancy and HIV outcomes. This cross-sectional analysis utilized enrollment data from a randomized trial (Mobile WAChX, NCT02400671) in six Kenyan public maternal and child health clinics. Depressive symptoms were assessed with the Patient Health Questionnaire-9 (PHQ-9), stigma with the Stigma Scale for Chronic Illness, and intimate partner violence (IPV) with the Abuse Assessment Screen. Correlates of moderate-to-severe depressive symptoms ("depression", PHQ-9 score ≥10) were assessed using generalized estimating equation models clustered by facility. Among 824 pregnant WLWH, 9% had depression; these women had more recent HIV diagnosis than those without depression (median 0.4 vs. 2.0 years since diagnosis, p = .008). Depression was associated with HIV-related stigma (adjusted Prevalence Ratio [aPR]:2.36, p = .025), IPV (aPR:2.93, p = .002), and lower social support score (aPR:0.99, p = .023). Using population-attributable risk percent to estimate contributors to maternal depression, 81% were attributable to stigma (27%), recent diagnosis (24%), and IPV (20%). Integrating depression screening and treatment in prevention of mother-to-child HIV transmission programs may be beneficial, particularly in women recently diagnosed or reporting stigma and IPV.

Project description:IntroductionIt is critical to increase the uptake of interventions proven to be effective to improve maternal and perinatal outcomes. Supply kits have been suggested to be a feasible strategy designed to ensure timely availability and effective follow-up of care.ObjectiveWe conducted a systematic review to summarize the evidence on the uptake, effectiveness and safety of supply kits for maternal care.Search strategyMEDLINE, the Cochrane Pregnancy and Childbirth Group's Trials Register, Campbell Collaboration, Lilacs, Embase and unpublished studies were searched.Selection criteriaStudies that reported the efficacy, safety and use of supply kits for maternal healthcare were eligible. Participants were pregnant women or in childbirth. Supply kits were defined as a collection of medicines, supplies or instruments packaged together with the aim of conducting a healthcare task.Data collection and analysisTwo reviewers independently performed the screening, data extraction, and methodological and quality assessment.Main results24 studies were included: 4 of them were systematic reviews and 20 primary studies. Eighteen studies evaluated a so-called "clean delivery kit". In all but two studies, the kits were used by more than half of the participants. A meta-analysis was deemed inappropriate due to the heterogeneity in study design, in the components of the interventions implemented, in the content of the kits, and in outcomes. Nine studies assessed neonatal outcomes and found statistically significant reductions in cord infection, sepsis and tetanus-related mortality in the intervention group. Three studies showed evidence of reduced neonatal mortality (OR 0.52, 0.60 and 0.71) with statistically significant confidence intervals in all cases. Four studies reported odd ratios for maternal mortality, but only one showed evidence of a statistically significant decrease in this outcome but it was ascribed to hand washing prior to childbirth and not with the use of kits.ConclusionThis review suggests potential benefits in the use of supply kits to improve maternal and neonatal health. However, the observational nature of the studies, the heterogeneity and the use of kits incorporated within complex interventions limit the interpretation of the findings.
