RESUMO
Children in low- and middle-income countries face an increased risk of impaired cognitive development due to contaminated environments, poor nutrition, and inadequate responsive stimulation from caregivers. Implementing multi-component, community-level interventions may reduce these risks; however, there is little evidence supporting implementation of these interventions at scale. We assessed the feasibility of implementing a group-based intervention that included responsive stimulation, maternal and child nutrition, water and sanitation, and childhood lead exposure prevention through the government health system in Chatmohar, Bangladesh. After implementation, we conducted 17 in-depth interviews with frontline health service providers and 12 key informant interviews with their supervisors and managers to explore the facilitators and difficulties implementing such a complex programme within the health system. Factors facilitating implementation included: high quality training and skill level of providers, support from community members, family, and supervisors, positive relationships between providers and participants, and provision of children's toys and books free of cost. Difficulties included increased workload of the providers, complicated group-based yet stage-specific delivery where providers had to manage a large group of mother-child dyads representing many different child age-groups at once, and logistics difficulties in providing toys and books through a centralised health system process. Key informants made suggestions to ensure effective government-level scale-up including engaging relevant NGOs as partners, identifying feasible ways to make toys available, and offering providers meaningful even if non-monetary rewards. These findings can be used to shape the design and delivery of multi-component child development interventions to be delivered through the health system.

BACKGROUND: Emergency departments (ED) are a critical touchpoint for patients with opioid use disorder (OUD). In 2019, Pennsylvania had the fifth highest drug overdose mortality rate in the United States. State efforts have focused on implementing evidence-based ED care protocols, including induction of buprenorphine and warm handoffs to community treatment. OBJECTIVE: We examined hospital staff's perspectives on the processes, challenges, and facilitators to buprenorphine initiation and warm handoff protocols in the ED. METHODS: We used a qualitative case study design to focus on six Pennsylvania hospitals. The study selected hospitals using purposive sampling to capture varying hospital size, rurality, teaching status, and phase of protocol implementation. The study staff interviewed hospital staff with key roles in OUD care delivery in the ED, which included administrators, physicians, nurses, recovery support professionals, care coordinators, a social worker, and a pharmacist. Guided by the Consolidated Framework for Implementation Research (CFIR), we conducted semi-structured virtual interviews with 21 key informants from June to November 2020. Interviews were transcribed, deductively coded, and analyzed using CFIR domains and constructs to summarize factors influencing implementation of OUD ED care protocols and warm handoff to care protocols, as well as suggestions that emerged between and across cases. RESULTS: Despite variation in the local context between hospitals, we identified common themes that influenced buprenorphine and warm handoffs across sites. Attention to hospital OUD care through state-level initiatives like the Hospital Quality Improvement Program generated hospital leadership buy-in toward implementing best OUD care practices. Factors at the hospital-level that influenced implementation success included supporting interdisciplinary OUD care champions, addressing knowledge gaps and biases around patients with OUD, having data systems that capture OUD care and integrate clinical protocols, incorporating patient comorbidities and non-medical needs into care, and fostering community provider linkages and capacity for warm handoffs. Although themes were largely consistent among hospital and staff types, protocol implementation was tailored by each hospital's size, patient volume, and hospital and community resources. CONCLUSIONS: By understanding frontline staff's perspectives around factors that impact OUD care practices in the ED, stakeholders may better optimize implementation efforts.

In low- and middle-income countries, most latrines are not accessible to young children. We explored how to modify existing pit latrines to make them child friendly. We conducted four focus group discussions with mothers to explore barriers to child latrine use. We then enrolled 20 households with a child aged 3-7 years old to test six enabling technologies developed based on the identified barriers. Two to three weeks after installing the selected enabling technologies in each household, researchers conducted 19 in-depth interviews with caregivers to explore the technologies' acceptance and feasibility. Common barriers included the discomfort of squatting on a large pan, fear of darkness, and fear of a slippery floor. Of the potential solutions, a ring to stabilize the child while squatting in the latrine was preferred by children and was affordable and available. A wooden board with a smaller hole than the usual pan reduced fears of falling and helped eliminate discomfort but was inconvenient to handle and clean. A transparent fiberglass roof tile was affordable, available, increased visibility, and kept the latrine floor dry. In conclusion, the fiberglass roof tile and stability ring were two affordable and locally available technologies that facilitated latrine use by children aged 3-7 years.

Community Health Workers (CHWs) can effectively implement maternal and child health interventions, but there is paucity of evidence on how to integrate child stimulation into these interventions, and their delivery at scale. In rural Bangladesh, CHWs implemented an intervention integrating psychosocial stimulation, nutrition, maternal mental health, water, sanitation, hygiene (WASH) and lead exposure prevention. In each of 16 intervention villages, one CHW worked with 20 households. CHWs bi-weekly held group meetings or alternated group meetings and home visits with pregnant women and lactating mothers. We assessed the intervention through five focus groups, four interviews and one group discussion with CHWs and their supervisors to explore success factors of implementation. CHWs' training, one-on-one supervision and introduction by staff to their own community, and adoption of tablet computers as job aids, enabled successful session delivery to convey behavioral recommendations. CHWs reported difficulties delivering session due to the complexity of behavioral recommendations and struggled with age-specific intervention material. Young children's attendance in group sessions generated distractions that undermined content delivery. We identified ways to minimize the difficulties to strengthen intervention-delivery during implementation, and scale-up. Iterative revisions of similarly integrated interventions based on qualitative evaluation findings could be delivered feasibly by CHWs and allow for implementation at scale.

Community health workers (CHWs) are key to implementing community-based health interventions and quality can be enhanced by better understanding their lived experiences. The WASH Benefits, Bangladesh trial engaged 540 female CHWs to promote varying health intervention packages. We report on factors influencing their lived experiences during the trial, to aid future recruitment, training and retention of CHWs. Nine focus groups and 18 in-depth interviews were conducted with CHWs. Focus groups and interviews were transcribed and thematic content analysis performed to summarize the results. All CHWs described experiencing positive working conditions and many benefits both socially and financially; these contributed to their retention and job satisfaction. Their honorarium was commonly applied towards their children's education and invested for income generation. CHWs gained self-confidence as women, to move unaccompanied in the community and speak in public. They earned respect from the community and their family members who helped them manage their family obligations during work and were viewed as a resource for advice on health and social issues. Many participated in family decision-making from which they were previously excluded. Health programs should foster a positive experience among their CHWs to aid the recruitment, retention and development of this important human resource.

In low- and middle-income countries (LMICs), hand sanitizer may be a convenient alternative to soap and water to increase hand hygiene practices. We explored perceptions, acceptability, and use of hand sanitizer in rural Bangladesh. We enrolled 120 households from three rural villages. Promoters distributed free alcohol-based hand sanitizer, installed handwashing stations (bucket with tap, stand, basin, and bottle for soapy water), and conducted household visits and community meetings. During Phase 1, promoters recommended handwashing with soap or soapy water, or hand sanitizer after defecation, after cleaning a child's anus/feces, and before food preparation. In Phase 2, they recommended separate key times for hand sanitizer: before touching a child ≤ 6 months and after returning home. Three to 4 months after each intervention phase, we conducted a survey, in-depth interviews, and group discussions with child caregivers and male household members. After Phase 1, 82/89 (92%) households reported handwashing with soap after defecation versus 38 (43%) reported hand sanitizer use. Participants thought soap and water removed dirt from their hands, whereas hand sanitizer killed germs. In Phase 2, 76/87 (87%) reported using hand sanitizer after returning home and 71/87 (82%) before touching a child ≤ 6 months. Qualitative study participants reported that Phase 2-recommended times for hand sanitizer use were acceptable, but handwashing with soap was preferred over hand sanitizer when there was uncertainty over choosing between the two. Hand sanitizer use was liked by household members and has potential for use in LMICs, including during the coronavirus pandemic.

Delivery of interventions through group sessions allows for in-depth discussions and creates opportunities for group members to work together to identify and solve common problems. However, low attendance may limit impact. We explored factors affecting attendance, active participation, and behavior change in an integrated group-based child development and maternal and child health intervention in Bangladesh. Community health workers (CHWs) facilitated two sessions a month including material on child stimulation; water, sanitation, and hygiene; nutrition, maternal depression, and lead exposure prevention. Sessions were conducted with 320 pregnant women and mothers with children younger than 24 months, in 16 villages in Kishoreganj district. After 4 and 9 months of intervention, we conducted focus group discussions and in-depth interviews with mothers (n = 55 and n = 48) to identify determinants of attendance and behavior change, and to examine potential for intervention scale-up. Recruiting family members to assist with childcare resulted in improved attention during sessions. Adopting a storytelling format for presentation of session materials resulted in more engaged participation during courtyard sessions. Session attendance and behavior change, especially purchasing decisions, were difficult for participants without the support of male heads of the household. Selecting a rotating leader from among the group members to remind group members to attend sessions and support CHWs in organizing the sessions was not successful. Facilitating self-appraisals and planning for water and sanitation allowed participants to identify areas for improvement and track their progress. Key determinants of a participant's attendance were identified, and the resulting intervention shows promise for future implementation at scale.

BACKGROUND: Home-based interventions have potential for improving early child development (ECD) in low-resource settings. The design of locally acceptable strategies requires an in-depth understanding of the household context. In this formative research study, we aimed to characterize the home play and learning environments of children 6-23 months of age from low-income households in peri-urban Lima, Peru. METHODS: Drawing on the developmental niche framework, we used quantitative and qualitative methods to understand children's physical and social settings, childcare practices, and caregiver perspectives. We conducted interviews, unstructured video-recorded observations, and spot-checks with 30 randomly selected caregiver-child dyads, 10 from each child age group of 6-11, 12-17, and 18-23 months of age, as well as key informant interviews with 12 daycare instructors. We analyzed the data for key trends and themes using Stata and ATLAS.ti and employed an adapted version of the Indicator of Parent-Child Interaction to evaluate the observations. RESULTS: Children's social settings were characterized by multi-generational homes and the presence of siblings and cousins as play partners. Access to books and complex hand-eye coordination toys (e.g., puzzles, building blocks) in the home was limited (30.0 and 40.0%, respectively). Caregivers generally demonstrated low or inconsistent levels of interaction with their children; they rarely communicated using descriptive language or introduced novel, stimulating activities during play. Reading and telling stories to children were uncommon, yet 93.3% of caregivers reported singing to children daily. On average, caregivers ascribed a high learning value to reading books and playing with electronic toys (rated 9.7 and 9.1 out of 10, respectively), and perceived playing with everyday objects in the home as less beneficial (rated 6.8/10). Daycare instructors reinforced the problems posed by limited caregiver-child interaction and supported the use of songs for promoting ECD. CONCLUSIONS: The features of the home learning environments highlighted here indicate several opportunities for intervention development to improve ECD. These include encouraging caregivers to communicate with children using full sentences and enhancing the use of everyday objects as toys. There is also great potential for leveraging song and music to encourage responsive caregiver-child interactions within the home setting.

BACKGROUND: In El Salvador, Aedes aegypti mosquitoes transmitting Zika and other arboviruses use water storage containers as important oviposition sites. Promotion of water storage container cleaning is a key element of prevention programs. We explored community perceptions surrounding cleaning practices among pregnant women, male partners of pregnant women, and women likely to become pregnant. METHODS: Researchers conducted 11 focus groups and 12 in-depth interviews which included individual elicitations of Zika prevention measures practiced in the community. Focus group participants rated 18 images depicting Zika-related behaviors according to effectiveness and feasibility in the community context, discussed influencing determinants, voted on community intentions to perform prevention behaviors, and performed washbasin cleaning simulations. In-depth interviews with male partners of pregnant women used projective techniques with images to explore their perceptions on a subset of Zika prevention behaviors. RESULTS: General cleaning of the home, to ensure a healthy environment, was a strong community norm. In this context, participants gave water storage container cleaning a high rating, for both its effectiveness and feasibility. Participants were convinced that they cleaned their water storage containers effectively against Zika, but their actual skills were inadequate to destroy Aedes aegypti eggs. A further constraint was the schedule of water availability. Even during pregnancy, male partners rarely cleaned water storage containers because water became available in homes when they were at work. Furthermore, prevailing gender norms did not foster male participation in domestic cleaning activities. Despite these factors, many men were willing to provide substantial support with cleaning when their partners were pregnant, in order to protect their family. CONCLUSIONS: Behavior change programs for the prevention of Zika and other arboviruses need to improve community members' mosquito egg destruction skills rather than perpetuate the promotion of non-specific cleaning in and around the home as effective. Egg elimination must be clearly identified as the objective of water storage container maintenance and programs should highlight the effective techniques to achieve this goal. In addition, programs must build the skills of family members who support pregnant women to maintain the frequency of effective egg destruction in all water storage containers of the home.

BACKGROUND: During the time a diarrhea patient presents at a health facility, the household members of the patient are at higher risk of developing diarrheal diseases (> 100 times for cholera) than the general population. The Cholera-Hospital-based-Intervention-for-7-Days (CHoBI7) is a health facility-initiated water treatment and handwashing with soap intervention designed to reduce transmission of diarrheal diseases between patients and their household members. The present research aimed to (1) develop a scalable approach to integrate the CHoBI7 intervention program into services provided at government and private health facilities in Bangladesh; and (2) tailor the intervention program for the household members of all diarrhea patients, irrespective of the etiology of disease. METHODS: We conducted 8 months of formative research, including 60 semi-structured interviews, 2 group discussions, and a pilot study. Thirty-two interviews were conducted with diarrhea patients and their family caregivers, government stakeholders, and health care providers both to explore existing WASH and diarrhea patient care practices in health facilities and to identify considerations for scaling the CHoBI7 program. Fifty-two diarrhea patient households participated in a pilot study of a modified version of the CHoBI7 intervention program for tailoring. Twenty-eight interviews and 2 group discussions were conducted with pilot households to explore experiences with and recommendations for intervention delivery. RESULTS: The intervention program was modified based on formative research findings. Pilot study participants recognized the benefits of the CHoBI7 intervention program and made suggestions to improve the acceptability and feasibility of the intervention. Modifications included 1) providing additional pictorial modules, cues to action, enabling technologies, and supplies for safe drinking water and handwashing with soap behaviors in the health facility; 2) switching out technology prone to breaks and leaks as well as sourcing plastic technologies from a high-quality, local manufacturer; and 3) including instructions discouraging the non-use or misuse of technologies and supplies. Considerations for scalability include the local availability and marketing of enabling technologies and supplies, staff for program delivery in health facilities, and potential integration into existing government or health promotion programs. CONCLUSIONS: Formative research identified important considerations for the content, delivery, and scalability of the CHoBI7 health facility-initiated WASH intervention program.

BACKGROUND: Zika remains an epidemiological threat in Latin America, including the Dominican Republic. Although transmitted by the same mosquito as Dengue and Chikungunya, Zika is unique in the potentially harmful consequences for babies born to women infected during pregnancy. Experts highlight the feminization of Zika, in terms of burden of disease and women's caregiving responsibilities. Understanding gender's role in Zika prevention, therefore, is key to strengthening current and future programs. METHODOLOGY/PRINCIPAL FINDINGS: This qualitative study, comprised of 12 focus group discussions and eight in-depth interviews, explored gender's role in Zika among pregnant and non-pregnant women as well as male partners of pregnant women in the Dominican Republic. Topics included perceptions about Zika and perceived feasibility and effectiveness of prevention behaviors (e.g. cleaning water storage containers, using condoms during pregnancy). Researchers applied grounded theory through a process of deductive coding-classifying data around predetermined categories-followed by inductive coding-identifying themes that emerged from coded data. Study findings uncovered three ways in which gender may influence Zika prevention. First, women are largely responsible for household chores-including cleaning water storage containers-with men as assistants. Second, men described their role in the family as the protector. Finally, men and women believed that partners would perceive suggesting condom use or abstinence during pregnancy as a sign of infidelity. CONCLUSIONS: Current/future Zika programs should address knowledge gaps, especially around water storage cleaning techniques and sexual transmission. Programs should also integrate gender into programming in culturally-relevant ways that avoid reinforcing stereotypes. Furthermore, programs should tailor activities for men, women, as well as the couple. In the end, integrating gender in a way that is mindful of the local context while not exploiting existing gender roles is critical for preventing Zika and similar mosquito-borne diseases, both in the Dominican Republic and throughout the region.

Zika virus, which is transmitted by Aedes aegypti mosquitoes and through sexual transmission, disproportionally affects the human fetus. Guatemala experienced a surge of Zika cases beginning in 2016. We conducted a qualitative study of community perceptions of the seriousness of Zika, as well as the effectiveness, feasibility, and collective efficacy of Zika prevention actions. Free listing elicited the preventive actions salient for 68 participants comprising pregnant women, men with a pregnant partner, and women likely to become pregnant; 12 focus group discussions in a highland and a lowland town explored other concepts through rank orderings of prevention practices depicted on cards. Participants' initial concern about Zika, based on recent experience with chikungunya and high media coverage, diminished because of its mild symptoms and reduced media coverage. Participants identified more than 32 salient preventive actions, many of which are considered effective by programs. Participants ranked water storage container cleaning and regular unspecified cleaning of the house and its surroundings as highly effective, feasible, and of high collective efficacy; however, the actions lacked the specificity needed to effectively destroy mosquito eggs. Community-level removal of tires and discarded containers had lower collective efficacy than household-level implementation because of the municipal and community cooperation needed. Condom use, although salient for Zika prevention, was hindered by gender roles. The findings indicate space for increasing self-efficacy for condom use among fathers-to-be, abandoning nonspecific terms such as "cleaning" and "standing water," increasing people's skills in using bleach as an ovicide, and promoting antenatal care and family planning counseling.

BACKGROUND: The Cholera-Hospital-Based-Intervention-for-7-Days (CHoBI7) is a handwashing with soap and water treatment intervention program delivered by a health promoter bedside in a health facility and through home visits to diarrhea patients and their household members during the 7 days after admission to a health facility. In a randomized controlled trial among cholera patient households in Bangladesh, the 7-day CHoBI7 program resulted in a significant reduction in cholera among household members of cholera patients and sustained improvements in drinking water quality and handwashing with soap practices 12 months post-intervention. In an effort to take this intervention to scale across Bangladesh in partnership with the Bangladesh Ministry of Health and Family Welfare, this study evaluates the feasibility and acceptability of mobile health (mHealth) programs as a low-cost, scalable approach for CHoBI7 program delivery. METHODS: Formative research for the development of the CHoBI7 mHealth intervention included 40 semi-structured interviews, 4 mHealth workshops, 2 group discussions, and a pilot study of 52 households to assess the feasibility and acceptability of the developed mHealth program. Thematic analysis of the interviews and group discussions was conducted by two individuals separately based on emergent themes, and then themes were compared and discussed. RESULTS: A theory- and evidence-based approach using qualitative research methods was implemented to design the CHoBI7 mHealth program. Semi-structured interviews with government stakeholders identified perceptions and preferences for scaling the CHoBI7 mHealth program. Group discussions and semi-structured interviews with diarrhea patients and their family members identified beneficiary perceptions of mHealth and preferences for CHoBI7 mHealth program delivery. mHealth workshops were conducted as an interactive approach to draft and refine mobile message content based on stakeholder preferences. The pilot findings indicate that the CHoBI7 mHealth program has high user acceptability and is feasible to deliver to diarrhea patients that present at health facilities for treatment in Bangladesh. Both text and voice messages were recommended for program delivery. Dr. Chobi, the sender of mHealth messages, was viewed as a credible source of information that could be shared with others. CONCLUSION: This study presents a theory- and evidence-based approach that can be implemented for the development of future water, sanitation, and hygiene mHealth programs in low-resource settings.

RESUMO
OBJECTIVE: The behavioural effect of large-scale handwashing promotion programmes has been infrequently evaluated, and variation in the effect over time has not been described. We assess the effect of a large-scale handwashing promotion programme on handwashing outcomes in a community setting in Dhaka, Bangladesh. METHODS: We analysed data from a cluster-randomised trial that included three arms: vaccine-and-behaviour-change intervention (VBC), vaccine-only (V) and no intervention (Control). Data collectors randomly selected different subsets of households each month during the study period and assessed: (i) temporal variation in availability of soap and water at handwashing place; (ii) the use of water and soap by participants when asked to demonstrate handwashing, and; (iii) handwashing behaviour according to structured observation. We used log-binomial regression analyses to calculate prevalence ratios (PRs) and 95% confidence intervals and compare outcomes by study arms. RESULTS: Data collectors surveyed 9325 households over 28 months. In VBC, there was a significant positive trend on availability of water and soap from baseline to 9 months after the start of the intervention (P-for-trends <0.001), and no significant trend during months 10-28 (P-for-trend = 0.297). In the entire study period, availability of water and soap was higher in VBC (43%) than in V (23%) (PR = 1.92; CI = 1.72, 2.15) and Control (28%) (PR = 1.53; CI = 1.38, 1.69) households. There were no differences between study arms with regard to use of soap during handwashing demonstrations. Observed handwashing with soap after toilet use was higher in VBC (17%) than in V (8%) (PR = 1.47, CI = 0.58, 3.75) and Control (2%) (PR = 3.47, CI = 0.48, 23.33) groups. At other possible pathogen transmission events, the prevalence of handwashing with soap was ≤3%. CONCLUSION: VBC households maintained soap and water for handwashing, but the prevalence of observed handwashing was low in all study arms. The results underscore the need to strengthen scalable behaviour change approaches.
OBJECTIF: L'effet sur le comportement des programmes de promotion du lavage des mains à grande échelle a été rarement évalué et aucune variation de cet effet dans le temps n'a été décrite. Nous évaluons les effets d'un programme de promotion du lavage des mains à grande échelle sur les résultats dans un cadre communautaire à Dhaka, au Bangladesh. MÉTHODES: Nous avons analysé les données d'un essai randomisé par grappes comprenant 3 groupes: intervention vaccin-changement de comportement (VBC), vaccin uniquement (V) et aucune intervention (contrôle). Les collecteurs de données ont sélectionné au hasard différents sous-ensembles de ménages chaque mois au cours de la période d'étude et ont évalué: 1) la variation temporelle de la disponibilité de savon et d'eau sur le lieu de lavage des mains, 2) l'utilisation d'eau et de savon par les participants lorsqu'on leur a demandé de faire la démonstration du lavage des mains, 3) le comportement du lavage des mains selon une observation structurée. Nous avons utilisé des analyses de régression log-binomiales pour calculer les ratios de prévalence (PR) et les intervalles de confiance à 95%, ainsi que pour comparer les résultats par groupe d'étude. RÉSULTATS: Les collecteurs de données ont interrogé 9325 ménages au cours de 28 mois. Dans le groupe VBC, il y avait une tendance positive significative sur la disponibilité d'eau et de savon de la ligne de base à 9 mois après le début de l'intervention (p-pour-tendances <0,001) et aucune tendance significative au cours des mois 10 à 28 (p-pour- tendance = 0,297). Sur l'ensemble de la période d'étude, la disponibilité en eau et en savon était plus élevée dans le groupe VBC (43%) que dans le groupe V (23%) (PR = 1,92; IC: 1,72 - 2,15) et dans le groupe contrôle (28%) (PR = 1,53; IC: 1,38 - 1,69). Il n'y avait pas de différence entre les groupes d'étude en ce qui concerne l'utilisation de savon lors de démonstrations de lavage des mains. Le lavage des mains observé avec du savon après l'utilisation des toilettes était plus élevé dans le groupe VBC (17%) que dans le groupe V (8%) (PR = 1,47; IC: 0,58 - 3,75) et dans le groupe témoin (2%) (PR = 3,47, IC: 0,48 - 23,33). Lors d'autres événements possibles de transmission d'agents pathogènes, la fréquence du lavage des mains au savon était ≤ 3%. CONCLUSION: Les ménages du groupe VBC ont maintenu du savon et de l'eau pour se laver les mains, mais la prévalence du lavage des mains observé était faible dans tous les groupes de l'étude. Les résultats soulignent la nécessité de renforcer les approches évolutives de changement de comportement.

BACKGROUND: Global health education and training experiences are in high demand. Mentorship plays an important role in successful training, but academic institutions often lack formalized mentorship support. This study aimed to evaluate perceptions of global health mentorship across disciplines at Johns Hopkins University and to understand how to better support faculty mentorship for global health training. METHODS: This is a retrospective study that used qualitative methods to assess the perceptions of students who participated in the Johns Hopkins Center for Global Health (CGH) field placement program from 2011-2013 and CGH faculty who may have served as their mentors. Qualitative data was gathered through 30 individual in-depth interviews and 4 focus groups capturing both faculty and student perspectives. Data were analyzed inductively until thematic saturation was reached; a theoretical model, which we call the "building blocks of global health mentorship" model, emerged to serve as an analytical and synthesizing framework. FINDINGS: A series of factors influenced global health mentorship from an individual to institutional level, including motivation, expectation alignment, finances, time, and knowledge. Both students and faculty reported the importance of motivation and aligned expectations to the mentorship experience and, more broadly, the overseas experience. Mentorship relationships were identified by students and faculty as either a catalyst or a hindrance to the training experience from both a personal and a professional point of view. Many faculty mentioned insufficient institutional support and financial resources, which negatively influenced their capacity to serve as mentors. CONCLUSIONS: Many factors, ranging from individual to institutional, influence mentorship for both faculty and students, which in turn influence international experiences. The underlying role of institutional support emerged as a highly salient influencing factor. Global health programs should harness the faculty and students' motivations and expectations, as well as provide better support to faculty serving as mentors.

The pork tapeworm, Taenia solium, is among the leading causes of preventable epilepsy in the world and is common in rural areas of developing countries where sanitation is limited and pigs have access to human feces. Prior studies in rural villages of Peru have observed clusters of T. solium cysticercosis among pigs that live near human tapeworm carriers. Such spatial analyses, however, have been limited by incomplete participation and substandard diagnostic tests. In this study, we evaluated the association between necropsy-confirmed cysticercosis in pigs and their distance to T. solium tapeworm carriers in six villages in northern Peru. A total of six (1.4%) tapeworm carriers were detected using copro-antigen enzyme-linked immunosorbent assay and seven of 10 (70%) pigs belonging to the tapeworm carriers were found with viable cyst infection on necropsy. This was significantly greater than the prevalence of viable cyst infection among pigs living < 500 m (11%) and > 500 m (0.5%) from a tapeworm carrier (P < 0.001 for distance trend). Similar statistically significant prevalence gradients were observed after adjustment for possible confounders and for other pig-level outcomes including infection with > 10 viable cysts, degenerated cyst infection, and serological outcomes. This investigation confirms that porcine cysticercosis clusters strongly around tapeworm carriers in endemic rural regions of northern Peru and supports interventions that target these hotspots.

Inappropriate complementary feeding contributes to linear growth faltering in early childhood. Behaviour change interventions have been effective at improving practice, but few studies have investigated the effects of multicomponent integrated interventions. We conducted a cluster-randomized controlled trial in rural Bangladesh in which geographic clusters were randomized into seven arms: water treatment (W), sanitation (S), handwashing (H), water, sanitation, and handwashing (WSH), improved nutrition with infant and young child feeding messages and lipid-based nutrient supplementation for 6- to 24-month olds (N), N+WSH, and control. The objective of this paper was to examine the independent and combined effects of interventions on indicators of complementary feeding. Approximately 1 and 2 years after initiation of the intervention, research assistants surveyed mothers about infant feeding practices. Complementary feeding was examined using the World Health Organization indicators of infant and young child feeding practices. We used Poisson regression models to estimate prevalence ratios and linear regression models for prevalence differences with clustered sandwich estimators to adjust for clustering. A total of 4,718 households from 720 clusters were surveyed at year 1 and 4,667 at year 2. The children in the nutrition arms had a higher prevalence of meeting the minimum dietary diversity score compared with controls (year 1: N: 66.4%; N+WSH: 65.0% vs. C:32.4%; year 2: N: 91.5%; N+WSH: 91.6% vs. C:77.7%). Children in the nutrition arms received diverse food earlier than the children in control arm. In addition, the average consumption of lipid-based nutrient supplementation was >90% in each follow-up. Nutrition-specific interventions could be integrated with nutrition-sensitive interventions such as WSH without compromising the uptake of the nutrition intervention.

BACKGROUND: Researchers typically report more on the impact of public health interventions and less on the degree to which interventions were followed implementation fidelity. We developed and measured fidelity indicators for the WASH Benefits Bangladesh study, a large-scale efficacy trial, in order to identify gaps between intended and actual implementation. METHODS: Community health workers (CHWs) delivered individual and combined water, sanitation, handwashing (WSH) and child nutrition interventions to 4169 enrolled households in geographically matched clusters. Households received free enabling technologies (insulated water storage container; sani-scoop, potty, double-pit, pour-flush latrine; handwashing station, soapy-water storage bottle), and supplies (chlorine tablets, lipid-based nutrient supplements, laundry detergent sachets) integrated with parallel behavior-change promotion. Behavioral objectives were drinking treated, safely stored water, safe feces disposal, handwashing with soap at key times, and age-appropriate nutrition behaviors. We administered monthly surveys and spot-checks to households from randomly selected clusters for 6 months early in the trial. If any fidelity measures fell below set benchmarks, a rapid response mechanism was triggered. RESULTS: In the first 3 months, functional water seals were detected in 33% (14/42) of latrines in the sanitation only arm; 35% (14/40) for the combined WSH arm; and 60% (34/57) for the combined WSH and Nutrition arm, all falling below the pre-set benchmark of 80%. Other fidelity indicators met the 65 to 80% uptake benchmarks. Rapid qualitative investigations determined that households concurrently used their own latrines with broken water seals in parallel with those provided by the trial. In consultation with the households, we closed pre-existing latrines without water seals, increased the CHWs' visit frequency to encourage correct maintenance of latrines with water seals, and discouraged water-seal removal or breakage. At the sixth assessment, 86% (51/59) of households were in sanitation only; 92% (72/78) in the combined WSH; and 93% (71/76) in the combined WSH and Nutrition arms had latrines with functional water seals. CONCLUSIONS: An intensive implementation fidelity monitoring and rapid response system proved beneficial for this efficacy trial. To implement a routine program at scale requires further research into an adaptation of fidelity monitoring that supports program effectiveness.

BACKGROUND: Water, sanitation, and hygiene (WASH) efficacy trials deliver interventions to the target population under optimal conditions to estimate their effects on outcomes of interest, to inform subsequent selection for inclusion in routine programs. A systematic and intensive approach to intervention delivery is required to achieve the high-level uptake necessary to measure efficacy. We describe the intervention delivery system adopted in the WASH Benefits Bangladesh study, as part of a three-paper series on WASH Benefits Intervention Delivery and Performance. METHODS: Community Health Workers (CHWs) delivered individual and combined WASH and nutrition interventions to 4169 enrolled households in geographically matched clusters. Households were provided with free enabling technologies and supplies, integrated with parallel behaviour-change promotion. Behavioural objectives were drinking treated, safely stored water, safe feces disposal, handwashing with soap at key times, and age-appropriate nutrition behaviours (birth to 24 months). The intervention delivery system built on lessons learned from prior WASH intervention effectiveness, implementation, and formative research studies. We recruited local CHWs, residents of the study villages, through transparent merit-based selection methods, and consultation with community leaders. CHW supervisors received training on direct intervention delivery, then trained their assigned CHWs. CHWs in turn used the technologies in their own homes. Each CHW counseled six to eight intervention households spread across a 0.2-2.2-km radius, with a 1:12 supervisor-to-CHW ratio. CHWs met monthly with supervisor-trainers to exchange experiences and adapt technology and behaviour-change approaches to evolving conditions. Intervention uptake was tracked through fidelity measures, with a priori benchmarks necessary for an efficacy study. RESULTS: Sufficient levels of uptake were attained by the fourth intervention assessment month and sustained throughout the intervention period. Periodic internal CHW monitoring resulted in discontinuation of a small number of low performers. CONCLUSIONS: The intensive intervention delivery system required for an efficacy trial differs in many respects from the system for a routine program. To implement a routine program at scale requires further research on how to optimize the supervisor-to-CHW-to-intervention household ratios, as well as other program costs without compromising program effectiveness.
