RESUMO
We conducted qualitative research among people with HIV (PWH) and care providers in Cape Town, South Africa to understand the impact of negative clinic experiences on adherence and support preferences. In-depth interviews were conducted with 41 patients with an unsuppressed viral load or a treatment gap, and focus group discussions with physicians, nurses, counselors, and community health workers. Questions addressed treatment history and adherence barriers, then participants evaluated evidence-based adherence interventions for potential scale up. Inductive analysis examined care experiences and corresponding preference for intervention options. More than half of PWH described negative experiences during clinic visits, including mistreatment by staff and clinic administration issues, and these statements were corroborated by providers. Those with negative experiences in care stated that fear of mistreatment led to nonadherence. Most patients with negative experiences preferred peer support groups or check-in texts to clinic-based interventions. We found that PWH's negative clinic experiences were a primary reason behind nonadherence and influenced preferences for support mechanisms. These findings emphasize the importance of HIV treatment adherence interventions at multiple levels both in and outside of the clinic, and providing more comprehensive training to providers to better serve PWH in adherence counseling, especially those who are most vulnerable..
RESUMO
BACKGROUND: South Africa bears a large HIV burden with 7.8 million people with HIV (PWH). However, due to suboptimal antiretroviral therapy (ART) adherence and retention in care, only 66% of PWH in South Africa are virally suppressed. Standard care only allows for suboptimal adherence detection when routine testing indicates unsuppressed virus. Several adherence interventions are known to improve HIV outcomes, yet few are implemented in routinely due to the resources required. Therefore, determining scalable evidence-based adherence support interventions for resource-limited settings (RLS) is a priority. The multiphase optimization strategy (MOST) framework allows for simultaneous evaluation of multiple intervention components and their interactions. We propose to use MOST to identify the intervention combination with the highest levels of efficacy and cost-effectiveness that is feasible and acceptable in primary care clinics in Cape Town. METHODS: We will employ a fractional factorial design to identify the most promising intervention components for inclusion in a multi-component intervention package to be tested in a future randomized controlled trial. We will recruit 512 participants initiating ART between March 2022 and February 2024 in three Cape Town clinics and evaluate acceptability, feasibility, and cost-effectiveness of intervention combinations. Participants will be randomized to one of 16 conditions with different combinations of three adherence monitoring components: rapid outreach following (1) unsuppressed virus, (2) missed pharmacy refill collection, and/or (3) missed doses as detected by an electronic adherence monitoring device; and two adherence support components: (1) weekly check-in texts and (2) enhanced peer support. We will assess viral suppression (<50 copies/mL) at 24 months as the primary outcome; acceptability, feasibility, fidelity, and other implementation outcomes; and cost-effectiveness. We will use logistic regression models to estimate intervention effects with an intention-to-treat approach, employ descriptive statistics to assess implementation outcomes, and determine an optimal intervention package. DISCUSSION: To our knowledge, ours will be the first study to use the MOST framework to determine the most effective combination of HIV adherence monitoring and support intervention components for implementation in clinics in a RLS. Our findings will provide direction for pragmatic, ongoing adherence support that will be key to ending the HIV epidemic. TRIAL REGISTRATION: ClinicalTrials.gov NCT05040841.

BACKGROUND: This study evaluated the effect of revisions to existing peer-counselor services, called Mentor Mothers (MM), at maternal and child health clinics on medication adherence for women living with HIV (WLWH) in Kenya and on early infant HIV testing. METHODS: The Enhanced Mentor Mother Program study was a 12-site, two-arm cluster-randomized trial enrolling pregnant WLWH from March 2017 to June 2018 (with data collection through September 2020). Six clinics were randomized to continued MM-supported standard care (SC). Six clinics were randomized to the intervention arm (INT = SC plus revised MM services to include more one-on-one interactions). Primary outcomes for mothers were defined as: (PO1) the proportion of days covered (PDC) with antiretroviral therapy (ART) ≥ 0.90 during the last 24-weeks of pregnancy; and (PO2) ≥ 0.90 PDC during the first 24-weeks postpartum. Secondary outcomes were infant HIV testing according to national guidelines (at 6, 24, and 48 weeks). Crude and adjusted risk differences between study arms are reported. RESULTS: We enrolled 363 pregnant WLHV. After excluding known transfers and subjects with incomplete data extraction, data were analyzed for 309 WLWH (151 SC, 158 INT). A small share achieved high PDC during the prenatal and postnatal periods (0.33 SC/0.24 INT achieved PO1; 0.30 SC/0.31 INT achieved PO2; crude or adjusted risk differences were not statistically significant). In addition, ~ 75% in both study arms completed viral load testing during year two after enrollment, with > 90% suppressed in both arms. For infants, ≥ 90% in both arms had at least one HIV test through study follow up (76 weeks) but testing on schedule according to PMTCT guidelines was uncommon. CONCLUSIONS: While national guidelines in Kenya recommended that all HIV-infected pregnant women take a daily antiretroviral regimen for life following a HIV diagnosis, results presented here indicate that a minor share achieved high medication coverage during the prenatal and postnatal periods analyzed. In addition, adjustments to Mentor-Mother services showed no improvement in study outcomes. The lack of effect for this behavioral intervention is relatively consistent with the existing literature to improve mother-infant outcomes along the PMTCT care cascade. CLINICAL TRIAL NUMBER: NCT02848235. Date of first trial registration 28/07/2016.

OBJECTIVE: To examine distinct patterns of IPV perpetration and examined gender equitable attitudes as a correlate of these patterns among men from six countries in Asia and the Pacific. DESIGN: 2011-12 UN Multi-country Study on Men and Violence cross-sectional study. SETTING: Households in Bangladesh, Cambodia, China, Indonesia, Sri Lanka and Papua New Guinea. PARTICIPANTS: 10,178 men aged 18-49 years residing in Bangladesh, Cambodia, China, Indonesia, Sri Lanka and Papua New Guinea. PRIMARY OUTCOMES MEASURE: Our primary outcome was distinct patterns of IPV perpetration which were derived from multilevel latent class analyses. RESULTS: The odds of being assigned to the Low All Forms of IPV Perpetration class than the High All Forms of IPV Perpetration class was lower for men in the middle tertile group than men in the high tertile group for gender equitable attitudes. The odds of being assigned to the High Emotional IPV Perpetration class than the High All Forms of IPV Perpetration class was greater for men in the low tertile group than men in the high tertile group for gender equitable attitudes. The odds of being assigned to the High Physical/Emotional/Economic IPV Perpetration class than the High All Forms of IPV Perpetration class was lower for men in the low tertile group than men in the high tertile group for gender equitable attitudes. CONCLUSIONS: Gender transformative interventions that use an adaptive, personalized approach to men's typology of IPV perpetration may be beneficial to reduce violence against for women in the Asia-Pacific region.

BACKGROUND: The Mobile Continuing Medical Education (mCME) 2.0 project was a randomized controlled trial that found that a 6-month text message-based CME intervention improved both the use of online medical training resources and medical knowledge among a cadre of HIV clinicians in Vietnam. This companion study analyzed intervention costs and cost-effectiveness. METHODS: We conducted (1) a financial analysis based on costs incurred during the trial's planning and implementation; (2) an economic analysis to consider resource utilization; and (3) cost-effectiveness analyses to estimate cost inputs relative to impact: increase in self-study (measured by visits to online courses) and increase in knowledge (measured by exam score improvement) (in 2016 US$). Finally, we estimated the economic cost of a 9-month national program and a 10-year scaled-up model (in 2021 US$). RESULTS: The total financial cost of the intervention was US$49,552; the main cost drivers were personnel time (71.4%) and technology inputs (14.9%). The total economic cost was estimated at US$92,212, with the same key cost inputs (representing 77.7% and 8.0%, respectively, of total costs). The financial cost per 10% increase in accessing online courses was US$923, while the cost of improving knowledge, measured by a 10% improvement in mean exam score across the study population, was US$32,057 (US$605 per intervention clinician). The comparable total economic cost of each improvement, respectively, was US$1,770 and US$61,452 (US$1,159 per intervention clinician). A future 9-month national program was estimated to cost US$37,403, while the full 10-year scaled-up program was estimated at US$196,446. CONCLUSIONS: This analysis indicates that leveraging mobile technology could be a feasible way to provide distance learning to health professions across Vietnam at a relatively low cost. Given the need for practical ways to expand CME in resource-constrained regions of the world, this approach warrants further study and possible adoption.

We assessed an intervention aimed at improving adherence to antiretroviral therapy (ART) among pregnant and postpartum women living with HIV (PPWLH). We randomized 133 pregnant women initiating ART in Uganda to receive text reminders generated by real time-enabled electronic monitors and data-informed counseling through 3 months postpartum (PPM3) or standard care. Intention-to-treat analyses found low adherence levels and no intervention impact. Proportions achieving ≥95% adherence in PPM3 were 16.4% vs. 9.1% (t = -1.14, p = 0.26) in intervention vs. comparison groups, respectively; 30.9% vs. 29.1% achieved ≥80% adherence. Additional analyses found significant adherence declines after delivery, and no effect on disease progression (CD4-cell count, viral load), though treatment interruptions were significantly fewer in intervention participants. Per-protocol analyses encompassing participants who used adherence monitors as designed experienced better outcomes, suggesting potential benefit for some PPWLH. The study was registered on ClinicalTrials.Gov (NCT02396394).

To support translation of evidence-based interventions into practice for HIV patients at high risk of treatment failure, we conducted qualitative research in Cape Town, South Africa. After local health officials vetted interventions as potentially scalable, we held 41 in-depth interviews with patients with elevated viral load or a 3-month treatment gap at community clinics, followed by focus group discussions (FGDs) with 20 providers (physicians/nurses, counselors, and community health care workers). Interviews queried treatment barriers, solutions, and specific intervention options, including motivational text messages, data-informed counseling, individual counseling, peer support groups, check-in texts, and treatment buddies. Based on patients' preferences, motivational texts and treatment buddies were removed from consideration in subsequent FGDs. Patients most preferred peer support groups and check-in texts while individual counseling garnered the broadest support among providers. Check-in texts, peer support groups, and data-informed counseling were also endorsed by provider sub-groups. These strategies warrant attention for scale-up in South Africa and other resource-constrained settings.

Violence experience has been consistently associated with HIV risks and substance use behaviors. Although many studies have focused on intimate partner violence (IPV), the role of violence at a structural level (i.e., police abuse) remains relevant for people who inject drugs. This study evaluated the association of IPV and police-perpetrated violence experiences with HIV risk behaviors and substance use in a cohort of HIV-positive people who inject drugs in Ukraine. We also evaluated possible moderation effects of gender and socioeconomic status in the links between violence exposure and HIV risk and polysubstance use behaviors. Data came from the Providence/Boston-CFAR-Ukraine Study involving 191 HIV-positive people who inject drugs conducted at seven addiction treatment facilities in Ukraine. Results from logistic regressions suggest that people who inject drugs and experienced IPV had higher odds of polysubstance use than those who did not experience IPV. Verbal violence and sexual violence perpetrated by police were associated with increased odds of inconsistent condom use. The odds of engaging in polysubstance use were lower for women in relation to police physical abuse. We found no evidence supporting socioeconomic status moderations. Violence experiences were associated with substance use and sexual HIV risk behaviors in this cohort of HIV-positive people who inject drugs in Ukraine. Trauma-informed prevention approaches that consider both individual and structural violence could improve this population's HIV risks.
RESUMEN: La experiencia de violencia se ha asociado sistemáticamente con las conductas de riesgo para la adquisición o transmisión del VIH y con el uso de sustancias. Aunque muchos estudios se han centrado en la violencia infligida por la pareja íntima (VPI), el papel de la violencia estructural (es decir, el abuso policial) sigue siendo relevante para las personas que se inyectan drogas. Este estudio evaluó la asociación entre las experiencias de violencia perpetrada por la policía y la pareja íntima con los conductas de riesgo para la adquisición o transmisión del VIH y el uso de sustancias en una cohorte de personas VIH positivas que se inyectan drogas en Ucrania. También evaluamos los posibles efectos de moderación del género y el estatus socioeconómico entre la exposición a la violencia y los comportamientos de riesgo para la transmisión del VIH y uso de múltiples sustancias. Los datos provienen del estudio Providence / Boston-CFAR-Ucrania en el que participaron 191 personas infectadas por el VIH que se inyectan drogas, realizado en siete centros de tratamiento de adicciones en Ucrania. Los resultados de las regresiones logísticas sugieren que, en comparación con las personas que se inyectan drogas que no experimentaron IPV, las que experimentaron IPV tenían mayor probabilidad de uso de múltiples sustancias. La violencia sexual perpetrada por la policía se asoció con mayores probabilidades de un uso inconsistente del condón. No encontramos evidencia que apoye las moderaciones de género o estatus socioeconómico. Las experiencias de violencia se asociaron con el uso de sustancias y las conductas sexuales de riesgo para la transmisión del VIH en esta cohorte de personas VIH positivas que se inyectan drogas en Ucrania. Los enfoques de prevención basados en las experiencias traumáticas que tienen en cuenta tanto la violencia individual como la estructural podrían mejorar las conductas de riesgo para la transmission del VIH de esta población.

Intimate partner violence (IPV), including physical, sexual, emotional, and economic violence, has profound immediate and long-term effects on individuals and communities worldwide. To date, few studies have focused on couples' reporting of IPV. The aim of this article is to present the results of a survey of couples' reporting of IPV and the individual, interpersonal, and social correlates of IPV in northern Tanzania. Four hundred fifty couples from Karatu District, Tanzania, completed a questionnaire measuring attitudes on gender norms and relations, men's experience of childhood trauma, and men's perpetration and women's experience of IPV. We found high levels of acceptance and experience of IPV: 72% of men justified a husband's perpetration of IPV, and 54% of men and 76% of women said that a woman should tolerate violence to keep her family together. The majority of women had ever experienced IPV (77.8%), and 73.6% and 69% had experienced IPV in the past 12 and 3 months, respectively. Men were significantly less likely to report that they had committed IPV: 63.6% ever, 48.9% in the past 12 months, and 46.2% in the past 3 months. Multivariate logistic regression found that younger men, men who reported gender inequitable attitudes, childhood trauma, multiple sexual partners, and alcohol use were significantly more likely to report IPV perpetration in the past 3 months. Younger women, and women with low levels of education and reported food shortages were significantly more likely to report IPV in the past 3 months. These results indicate that social and individual acceptance and justification of IPV are common. Experience of violence persists over time in many relationships. This study demonstrates the need for interventions that address individual-, interpersonal-, and community-level determinants of IPV, including attitudes regarding gender equity, exposure to violence as children and intergenerational violence, lack of education, and poverty.

BACKGROUND: Uganda has successfully reduced pediatric HIV infections through prevention of mother-to-child transmission of HIV (PMTCT) programs, yet little is known about adherence to infant-specific components of interventions. We hypothesized that infants born to mothers receiving the WiseMama (WM) electronic drug monitoring (EDM)-based adherence intervention would have increased uptake of six-week post-natal nevirapine (NVP) infant prophylaxis and better adherence to six-week early infant diagnosis (EID) HIV testing. METHODS: At two sites in Uganda, the Wise Infant Study (WIN) prospectively followed an infant cohort. Infants were born to women enrolled in an RCT testing the effect of real-time reminders delivered via EDM on maternal adherence to antiretroviral therapy. We assessed intrapartum and discharge receipt of NVP prophylaxis using pharmacy and infant HIV DNA testing laboratory data. RESULTS: Of 121 women eligible for WIN, 97 (80%) consented and enrolled; 46 had been randomized to control and 51 to intervention. There were no differences in receipt of a six-week NVP supply (control 87%, intervention 82%, p = 0.53). Receipt of any NVP prophylaxis did not vary by delivery location (p = 0.35), and although 12% of infants were delivered at non-study health facilities, they were not less likely to receive NVP at discharge (p = 0.37). Among infants with a completed HIV test, there was no difference in mean time to first test (control 52 days (SD 18), intervention 51 days (SD 15), p = 0.86). Only one infant, in the control group, tested positive for HIV. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS: We found no significant differences in adherence to infant PMTCT practices between intervention and control infants with relatively high rates of NVP receipt albeit with suboptimal adherence to six-week EID testing. Further work is needed to ensure improved access, uptake, and follow-up of HIV-exposed infants in the Option B+ era.
RESUMO
We tested an intervention that aimed to increase retention in antiretroviral therapy (ART) among HIV-positive pregnant and postpartum women, a population shown to be vulnerable to poor ART outcomes. 133 pregnant women initiating ART at 2 hospitals in Uganda used real time-enabled wireless pill monitors (WPM) for 1 month, and were then randomized to receive text message reminders (triggered by late dose-taking) and data-informed counseling through 3 months postpartum or standard care. We assessed "full retention" (proportion attending all monthly clinic visits and delivering at a study facility; "visit retention" (proportion of clinic visits attended); and "postpartum retention" (proportion retained at 3 months postpartum). Intention-to-treat and per protocol analyses found that retention was relatively low and similar between groups, with no significant differences. Retention declined significantly post-delivery. The intervention was unsuccessful in this population, which experiences suboptimal ART retention and is in urgent need of effective interventions.

Pneumonia remains a leading cause of morbidity and mortality in young children. The total cost of pneumonia-related hospitalization, including household-level cost, is poorly understood. To better understand this burden in an urban setting in South America, we incorporated a cost study into a trial assessing zinc supplements in treatment of severe pneumonia among children aged 2-59 months at a public hospital in Quito, Ecuador, which provides such treatment at no charge. Data were collected from children's caregivers at hospitalization and discharge on out-of-pocket payments for medical and nonmedical items, and on employment and lost work time. Analyses encompassed three categories: direct medical costs, direct nonmedical costs, and indirect costs, which covered foregone wages (from caregivers' self-reported lost earnings) and opportunity cost of caregivers' lost time (based on the unskilled labor wage in Ecuador). Caregivers of 153 children completed all questionnaires. Overall, 57% of children were aged less than 12 months, and 46% were female. Just over 50% of mothers and fathers had completed middle school. Most reported direct costs, which averaged $33. Most also reported indirect costs, the mean of which was $74. Fifty-seven reported lost earnings (mean = $79); 29 reported lost time (estimated mean cost = $37). Stratified analyses revealed similar costs for children < 12 months and ≥ 12 months, with variations for specific items. Costs for hospital-based treatment of severe pneumonia in young children represent a major burden for households in low- to middle-income settings, even when such treatment is intended to be provided at no cost.

Intimate-partner violence (IPV) is a major public health issue that disproportionately affects women, especially in Tanzania where 40% of women report experiencing IPV. While IPV research has focused on IPV victims and perpetrators, community leaders can provide valuable insight on IPV at the community level. We conducted 50 key informant interviews with community leaders in nine villages in the Karatu district. These leaders identified common themes regarding IPV causes and consequences, reporting methods, and future recommendations. This information can help mitigate IPV at the community level in future interventions and shows community leaders themselves could be powerful tools in future IPV programming.

BACKGROUND: In the typical prevention of mother to child transmission (PMTCT) of HIV cascade of care discussion or analysis, the period of analysis begins at the first visit for antenatal care (ANC) for that pregnancy. This starting point is problematic for two reasons: (1) a large number of HIV-infected women are already on life-long antiretroviral therapy (ART) when presenting for ANC; and (2) women present to ANC at different gestational ages. The PMTCT ART Coverage Tool (PMTCT-ACT), which estimates the proportion of days covered (PDC) with ART, was developed to address each of these problems. METHODS: PDC is a preferred method to measure adherence to chronic medications, such as ART. For evaluating the PMTCT cascade of care, as indicated by PDC with ART over various time periods, a "starting point" based on a specific day before delivery must be defined that applies to all women (treatment experienced or naïve at the first ANC visit at any gestational age). Using the example of 168 days prior to delivery (24 weeks), PMTCT-ACT measures PDC with ART during that period. PMTCT-ACT is provided as a STATA do-file. Using an example dataset for two women (ID1 is treatment experienced; ID2 is treatment naïve), the details of each major portion of the tool (Parts 1-5) are presented. PMTCT-ACT along with the intermediate datasets created during the analysis are provided as supplemental files. CONCLUSIONS: Evaluating the PMTCT cascade of care requires a standard definition of the follow-up period during pregnancy that applies to all HIV-infected pregnant women and a standard measure of adherence. PMTCT-ACT is a new tool that fits this purpose. PMTCT-ACT can also be easily adjusted to evaluate other ante- and post-natal periods (e.g., final 4 weeks, final 8 weeks, complete pregnancy period, initial 24 weeks postpartum, time periods consistent with infant HIV testing guidelines).
RESUMO
BACKGROUND: In 2014, Vietnam was the first Southeast Asian country to commit to achieving the World Health Organization's 90-90-90 global HIV targets (90% know their HIV status, 90% on sustained treatment, and 90% virally suppressed) by 2020. This pledge represented further confirmation of Vietnam's efforts to respond to the HIV epidemic, one feature of which has been close collaboration with the U.S. President's Emergency Plan for AIDS Relief (PEPFAR). Starting in 2004, PEPFAR supported community outreach programs targeting high-risk populations (people who inject drugs, men who have sex with men, and sex workers). To provide early evidence on program impact, in 2007-2008 we conducted a nationwide evaluation of PEPFAR-supported outreach programs in Vietnam. The evaluation focused on assessing program effect on HIV knowledge, high-risk behaviors, and HIV testing among high-risk populations-results relevant to Vietnam's push to meet global HIV goals. METHODS: We used a mixed-methods cross-sectional evaluation design. Data collection encompassed a quantitative survey of 2199 individuals, supplemented by 125 in-depth interviews. Participants were members of high-risk populations who reported recent contact with an outreach worker (intervention group) or no recent contact (comparison group). We assessed differences in HIV knowledge, risky behaviors, and HIV testing between groups, and between high-risk populations. RESULTS: Intervention participants knew significantly more about transmission, prevention, and treatment than comparison participants. We found low levels of injection drug-use-related risk behaviors and little evidence of program impact on such behaviors. In contrast, a significantly smaller proportion of intervention than comparison participants reported risky sexual behaviors generally and within each high-risk population. Intervention participants were also more likely to have undergone HIV testing (76.1% vs. 47.0%, p < 0.0001) and to have received pre-test (78.0% vs. 33.7%, p < 0.0001) and post-test counseling (80.9% vs. 60.5%, p < 0.0001). Interviews supported evidence of high impact of outreach among all high-risk populations. CONCLUSIONS: Outreach programs appear to have reduced risky sexual behaviors and increased use of HIV testing services among high-risk populations in Vietnam. These programs can play a key role in reducing gaps in the HIV care cascade, achieving the global 90-90-90 goals, and creating an AIDS-free generation.

In Tanzania, women suffer high rates of intimate partner violence (IPV). We conducted a pilot cluster randomised controlled trial to test the feasibility, acceptability and preliminary effectiveness of IPV prevention interventions targeting men and communities in nine villages randomly assigned to one of three study arms (n = 450 couples). In the Control Group, women participated in savings groups while male partners received no intervention. In Intervention Group 1, women participated in savings groups and men participated in peer-groups addressing gender relations and IPV prevention. In Intervention Group 2, women participated in savings groups, men participated in peer-groups, and community leaders facilitated dialogues on similar topics. Recruitment was completed within one month with 95% retained in the intervention and 81% retained in the endline survey. Acceptability was high, with men participating in 82% of peer-group session hours. More men in Interventions 1 (24%) and 2 (19%) disagreed with wife-beating compared to men in the Control (13%); and more men reported non-perpetration of IPV in Interventions 1 (16%) and 2 (14%) compared to the Control (-2%). Findings suggest a fully powered RCT may detect significant reductions in men's justification and use of IPV, paving the way for evidence-based violence prevention programming. Trial registration: This study is registered with ClinicalTrials.gov. Identifier: NCT02434796.

Little is known about the factors that contribute to the losses during stages of the HIV continuum of care (CoC) and specifically during the latter stages of antiretroviral (ART) adherence and retention in HIV care among adolescents living with HIV/AIDS (ALHA) in sub-Saharan Africa. We conducted a mixed-methods study: six focus group discussions with 43 ALHA (age 17-19); in-depth interviews with four (age 18-19): and survey-based interviews with 330 ALHA (age 18-19) to identify, understand, and describe factors contributing to the losses in the latter stages of the CoC among ALHA in Zambia. Through focus group discussions and in-depth interviews, ALHA identified barriers at the intrapersonal level (e.g., poverty; lack of adequate nutrition; fear of stigma), interpersonal level (e.g., stigma; disrespectful treatment by providers), institutional/facility level (e.g., lack of adolescent specific services), and community level (e.g., lack of collaboration among organizations; social norms). In quantitative interviews, we found that 46% (101/220) of ALHA reported missing any clinic appointments in the past three months, and about 19% (41/221) reporting missing one or more doses of ART in the last week. Logistic regressions indicate that walking to the site of appointment and being currently employed were predictive of missed visits. Findings highlight the complexity of the multiple factors that are unique to ALHA in Zambia, which should be addressed to improve adherence to ART and retention in HIV.

BACKGROUND: Mobile technology is a novel approach for delivering continuing medical education (CME), with numerous advantages including lower costs and the ability to reach larger numbers than traditional in-person CME workshops. METHODS: From May 2015 to May 2017, we conducted two randomized controlled trials in a phased approach to evaluate the effectiveness of a mobile CME (mCME) approach for two cadres of health professionals in Vietnam. The first randomized controlled trial (RCT) tested the use of an SMS-based educational intervention among Community-Based Physician's Assistants; while feasible and acceptable, this intervention failed to improve medical knowledge among participants. Given the failure of the first RCT, and drawing on qualitative work conducted with participants at the conclusion of the trial, various modifications were employed in the second RCT conducted among HIV specialist physicians in Vietnam. Version 2.0 of the mCME intervention did lead to significant improvement in medical knowledge among intervention participants. Here, we discuss in detail the development of an mCME platform and the experiential "lessons learned" during two phases of implementation. RESULTS: Numerous lessons were learned during implementation, including the importance of: (I) mixed methods approaches; (II) an underlying theoretical framework for behavior change projects; (III) expertise in software programming; (IV) aligning educational content to a well-defined participant population; and (V) engaging and motivating adult learners. We also discuss the critical importance of projects with local ownership and investment that are relevant to local problems. CONCLUSIONS: mHealth approaches for continued healthcare training and education is increasingly relevant in many low-resource settings, the lessons learned here will be valuable to other organizations looking to scale-up similar mHealth-type educational programmes.
RESUMO
BACKGROUND: The Mobile Continuing Medical Education Project (mCME V.2.0) was a randomized controlled trial designed to test the efficacy of a text messaging (short message service [SMS])-based distance learning program in Vietnam that included daily quiz questions, links to readings and online courses, and performance feedback. The trial resulted in significant increases in self-study behaviors and higher examination scores for intervention versus control participants. OBJECTIVE: The objective of this mixed-methods study was to conduct qualitative and quantitative investigations to understand participants' views of the intervention. We also developed an explanatory framework for future trial replication. METHODS: At the endline examination, all intervention participants completed a survey on their perspectives of mCME and self-study behaviors. We convened focus group discussions to assess their experiences with the intervention and attitudes toward continuing medical education. RESULTS: A total of 48 HIV specialists in the intervention group completed the endline survey, and 30 participated in the focus group discussions. Survey and focus group data suggested that most clinicians liked the daily quizzes, citing them as convenient mechanisms to convey information in a relevant manner. A total of 43 of the 48 (90%) participants reported that the daily quizzes provided motivation to study for continuing medical education purposes. Additionally, 83% (40/48) of intervention participants expressed that they were better prepared to care for patients with HIV in their communities, compared with 67% (32/48) at baseline. Participation in the online coursework component was low (only 32/48, 67% of intervention participants ever accessed the courses), but most of those who did participate thought the lectures were engaging (26/32, 81%) and relevant (29/32, 91%). Focus group discussions revealed that various factors influenced the clinicians' decision to engage in higher learning, or "lateral learning," including the participant's availability to study, professional relevance of the topic area, and feedback. These variables serve as modifying factors that fit within an adapted version of the health belief model, which can explain behavior change in this context. CONCLUSIONS: Qualitative and quantitative endline data suggested that mCME V.2.0 was highly acceptable. Participant behaviors during the trial fit within the health belief model and can explain the intervention's impact on improving self-study behaviors. The mCME platform is an evidence-based approach with the potential for adoption at a national scale as a method for promoting continuing medical education.

RESUMO
BACKGROUND: A mobile-based continuing medical education (mCME) intervention implemented over 6 months between 2016 and 2017, consisting of daily SMS multiple choice quizzes and access to online daily readings and CME courses, was shown to be effective in increasing medical knowledge among HIV providers in Vietnam. We hypothesized this improvement was a result of "lateral learning," a process in which the daily SMS quizzes acted as a stimulus for interacting with other study materials. METHODS: We explored how study materials directly provided by the intervention-the daily readings and the online CME courses-and independent study behaviors, such as using medical textbooks and reviewing national guidelines, contributed to medical knowledge as measured by baseline and endline exams. At baseline, there were 53 participants each in the intervention and control groups (N=106). Using linear regression models, we estimated the association between intervention-prompted and independent study behaviors and endline test scores. We also conducted a series of interaction analyses to test the extent to which the effect of daily quiz performance on endline test scores depended on use of the intervention-prompted or independent study materials. Finally, we estimated the proportion of variance in endline test scores explained by each of the intervention-prompted behaviors. RESULTS: The average medical knowledge test score among all participants was 46% at baseline and 54% at endline. Among the intervention group, 82% of the daily quizzes were answered, although only about half were answered correctly. Responding to the daily quizzes (ß=0.24; P=.05), quiz performance (ß=0.42; P<.001), and accessing daily readings (ß=0.22; P=.06) were statistically significantly associated with higher endline test scores. While accessing the online CME courses and some of the independent study behaviors, such as use of medical textbooks, had positive associations with endline test scores, none reached statistical significance. Quiz performance explained 51% of the variation in endline test scores. Interaction analysis found that quiz performance had a stronger, but not statistically significant, association with endline test scores when both daily readings (ß=0.87; P=.08) and online CME courses (ß=0.25; P=.09) were accessed more frequently. CONCLUSION: In mCME interventions, daily SMS quizzes can effectively act as a stimulus for uptake of study behaviors when paired with access to relevant readings and online courses. While further investigation is needed to more fully understand the role of outside study materials, we believe this model has the potential for further use in Vietnam and other low-resource settings.
