ABSTRACT
BACKGROUND: Second-hand smoke exposure from tobacco significantly contributes to morbidity and mortality worldwide. A cluster RCT in Bangladesh compared a community-based smoke-free home (SFH) intervention delivered in mosques, with or without indoor air quality (IAQ) feedback to households to no intervention. Neither was effective nor cost-effective compared to no intervention using an objective measure of second-hand smoke. This paper presents the process evaluation embedded within the trial and seeks to understand this. METHODS: A mixed method process evaluation comprising interviews with 30 household leads and six imams (prayer leader in mosque), brief questionnaire completed by 900 household leads (75% response), fidelity assessment of intervention delivery in six (20%) mosques and research team records. Data were triangulated using meta-themes informed by three process evaluation functions: implementation, mechanisms of impact and context. RESULTS: IMPLEMENTATION: Frequency of SFH intervention delivery was judged moderate to good. However there were mixed levels of intervention fidelity and poor reach. Linked Ayahs (verses of the Qur'an) with health messages targeting SHS attitudes were most often fully implemented and had greatest reach (along with those targeting social norms). Frequency and reach of the IAQ feedback were good. MECHANISMS OF IMPACT: Both interventions had good acceptability. However, views on usefulness of the interventions in creating a SFH were mixed. Individual drivers to behaviour change were new SFH knowledge with corresponding positive attitudes, social norms and intentions. Individual barriers were a lack of self-efficacy and plans. CONTEXT: Social context drivers to SFH intervention implementation in mosques were in place and important. No context barriers to implementation were reported. Social context drivers to SHS behaviour change were children's requests. Barriers were women's reluctance to ask men to smoke outside alongside general reluctance to request this of visitors. (Not) having somewhere to smoke outside was a physical context (barrier) and driver. CONCLUSIONS: Despite detailed development and adaption work with relevant stakeholders, the SFH intervention and IAQ feedback became educational interventions that were motivational but insufficient to overcome significant context barriers to reduce objectively measured SHS exposure in the home. Future interventions could usefully incorporate practical support for SFH behaviour change. Moreover, embedding these into community wide strategies that include practical cessation support and enforcement of SFH legislation is needed.

INTRODUCTION: Deaths from second-hand smoke (SHS) exposure are increasing, but there is not sufficient evidence to recommend a particular SHS intervention or intervention development approach. Despite the available guidance on intervention reporting, and on the role and nature of pilot and feasibility studies, partial reporting of SHS interventions is common. The decision-making whilst developing such interventions is often under-reported. This paper describes the processes and decisions employed during transitioning from the aim of adapting an existing mosque-based intervention focused on public health messages, to the development of the content of novel community-based Smoke-Free Home (SFH) intervention. The intervention aims to promote smoke-free homes to reduce non-smokers' exposure to SHS in the home via faith-based messages. METHODS: The development of the SFH intervention had four sequential phases: in-depth interviews with adults in households in Dhaka, identification of an intervention programme theory and content with Islamic scholars from the Bangladesh Islamic Foundation (BIF), user testing of candidate intervention content with adults, and iterative intervention development workshops with Imams and khatibs who trained at the BIF. RESULTS: It was judged inappropriately to take an intervention adaptation approach. Following the identification of an intervention programme theory and collaborating with stakeholders in an iterative and collaborative process to identify barriers, six potentially modifiable constructs were identified. These were targeted with a series of behaviour change techniques operationalised as Quranic verses with associated health messages to be used as the basis for Khutbahs. Following iterative user testing, acceptable intervention content was generated. CONCLUSION: The potential of this community-based intervention to reduce SHS exposure at home and improve lung health among non-smokers in Bangladesh is the result of an iterative and collaborative process. It is the result of the integration of behaviour change evidence and theory and community stakeholder contributions to the production of the intervention content. This novel combination of intervention development frameworks demonstrates a flexible approach that could provide insights for intervention development in related contexts.
ABSTRACT
BACKGROUND: Brief behavioural support can effectively help tuberculosis (TB) patients quit smoking and improve their outcomes. In collaboration with TB programmes in Bangladesh, Nepal and Pakistan, we evaluated the implementation and scale-up of cessation support using four strategies: (1) brief tobacco cessation intervention, (2) integration of tobacco cessation within routine training, (3) inclusion of tobacco indicators in routine records and (4) embedding research within TB programmes. METHODS: We used mixed methods of observation, interviews, questionnaires and routine data. We aimed to understand the extent and facilitators of vertical scale-up (institutionalization) within 59 health facility learning sites in Pakistan, 18 in Nepal and 15 in Bangladesh, and horizontal scale-up (increased coverage beyond learning sites). We observed training and surveyed all 169 TB health workers who were trained, in order to measure changes in their confidence in delivering cessation support. Routine TB data from the learning sites were analysed to assess intervention delivery and use of TB forms revised to report smoking status and cessation support provided. A purposive sample of TB health workers, managers and policy-makers were interviewed (Bangladesh n = 12; Nepal n = 13; Pakistan n = 19). Costs of scale-up were estimated using activity-based cost analysis. RESULTS: Routine data indicated that health workers in learning sites asked all TB patients about tobacco use and offered them cessation support. Qualitative data showed use of intervention materials, often with adaptation and partial implementation in busy clinics. Short (1-2 hours) training integrated within existing programmes increased mean confidence in delivering cessation support by 17% (95% CI: 14-20%). A focus on health system changes (reporting, training, supervision) facilitated vertical scale-up. Dissemination of materials beyond learning sites and changes to national reporting forms and training indicated a degree of horizontal scale-up. Embedding research within TB health systems was crucial for horizontal scale-up and required the dynamic use of tactics including alliance-building, engagement in the wider policy process, use of insider researchers and a deep understanding of health system actors and processes. CONCLUSIONS: System-level changes within TB programmes may facilitate routine delivery of cessation support to TB patients. These strategies are inexpensive, and with concerted efforts from TB programmes and donors, tobacco cessation can be institutionalized at scale.

INTRODUCTION: Smokeless tobacco (ST) remains poorly regulated in Bangladesh. This study describes the prevalence and trends of ST use in Bangladesh, presents ST-related disease burden, identifies relevant policy gaps, and highlights key implications for future policy and practice for effective ST control in Bangladesh. METHODS: We analyzed secondary data from the two rounds (2009 and 2017) of The Global Adult Tobacco Survey, estimated ST-related disease burden, and conducted a review to assess differences in combustible tobacco and ST policies. In addition, we gathered views in a workshop with key stakeholders in the country on gaps in existing tobacco control policies for ST control in Bangladesh and identified policy priorities using an online survey. RESULTS: Smokeless tobacco use, constituting more than half of all tobacco use in Bangladesh, declined from 27.2% (25.9 million) in 2009 to 20.6% (22 million) in 2017. However, in 2017, at least 16947 lives and 403460 Disability-Adjusted Life Years (DALYs) were lost across Bangladesh due to ST use compared to 12511 deaths and 324020 DALYs lost in 2010. Policy priorities identified for ST control have included: introducing specific taxes and increasing the present ad valorem tax level, increasing the health development surcharge, designing and implementing a tax tracking and tracing system, standardizing ST packaging, integrating ST cessation within existing health systems, comprehensive media campaigns, and licensing of ST manufactures. CONCLUSIONS: Our analysis shows that compared to combustible tobacco, there remain gaps in implementing and compliance with ST control policies in Bangladesh. Thus, contrary to the decline in ST use and the usual time lag between tobacco exposure and the development of cancers, the ST-related disease burden is still on the rise in Bangladesh. Strengthening ST control at this stage can accelerate this decline and reduce ST related morbidity and mortality.
ABSTRACT
BACKGROUND: Thousands of Rohingya refugee mothers at the world's largest refugee camp located in Bangladesh are at risk of poor mental health. Accordingly, their children are also vulnerable to delayed cognitive and physical development. OBJECTIVE: The aim of this study is to evaluate the effectiveness of an integrated care package in reducing the prevalence of developmental delays among children aged 1 year and improving their mothers' mental health status. METHODS: This is a parallel, two-arm, single-blind, cluster randomized controlled trial (cRCT). A total of 704 mother-child dyads residing at the Kutupalong refugee camp in Cox's Bazar, Bangladesh, will be recruited from 22 clusters with 32 mother-child dyads per cluster. In the intervention arm, an integrated early childhood development and maternal mental health package will be delivered every quarter to mothers of newborns by trained community health workers until the child is 1 year old. Our primary outcome is a reduction in the prevalence of two or more childhood developmental delays of infants aged 1 year compared to the usual treatment. The secondary outcomes include reduced stunting among children and the prevalence of maternal depression. We will also assess the cost-effectiveness of the integrated intervention, and will further explore the intervention's acceptability and feasibility. RESULTS: At the time of submission, the study was at the stage of endpoint assessment. The data analysis started in December 2020, and the results are expected to be published after the first quarter of 2021. CONCLUSIONS: This study will address the burden of childhood developmental delays and poor maternal mental health in a low-resource setting. If proven effective, the delivery of the intervention through community health workers will ensure the proposed intervention's sustainability.

ABSTRACT
BACKGROUND: The prevalence of type 2 diabetes is increased in individuals with mental disorders. Much of the burden of disease falls on the populations of low- and middle-income countries (LMICs). OBJECTIVES: To assess the effects of pharmacological, behaviour change, and organisational interventions versus active and non-active comparators in the prevention or delay of type 2 diabetes among people with mental illness in LMICs. SEARCH METHODS: We searched the Cochrane Common Mental Disorders Controlled Trials Register, CENTRAL, MEDLINE, Embase and six other databases, as well as three international trials registries. We also searched conference proceedings and checked the reference lists of relevant systematic reviews. Searches are current up to 20 February 2020. SELECTION CRITERIA: Randomized controlled trials (RCTs) of pharmacological, behavioural or organisational interventions targeting the prevention or delay of type 2 diabetes in adults with mental disorders in LMICs. DATA COLLECTION AND ANALYSIS: Pairs of review authors working independently performed data extraction and risk of bias assessments. We conducted meta-analyses using random-effects models. MAIN RESULTS: One hospital-based RCT with 150 participants (99 participants with schizophrenia) addressed our review's primary outcome of prevention or delay of type 2 diabetes onset. Low-certainty evidence from this study did not show a difference between atypical and typical antipsychotics in the development of diabetes at six weeks (risk ratio (RR) 0.46, 95% confidence interval (CI) 0.03 to 7.05) (among a total 99 participants with schizophrenia, 68 were in atypical and 31 were in typical antipsychotic groups; 55 participants without mental illness were not considered in the analysis). An additional 29 RCTs with 2481 participants assessed one or more of the review's secondary outcomes. All studies were conducted in hospital settings and reported on pharmacological interventions. One study, which we could not include in our meta-analysis, included an intervention with pharmacological and behaviour change components. We identified no studies of organisational interventions. Low- to moderate-certainty evidence suggests there may be no difference between the use of atypical and typical antipsychotics for the outcomes of drop-outs from care (RR 1.31, 95% CI 0.63 to 2.69; two studies with 144 participants), and fasting blood glucose levels (mean difference (MD) 0.05 lower, 95% CI 0.10 to 0.00; two studies with 211 participants). Participants who receive typical antipsychotics may have a lower body mass index (BMI) at follow-up than participants who receive atypical antipsychotics (MD 0.57, 95% CI 0.33 to 0.81; two studies with 141 participants; moderate certainty of evidence), and may have lower total cholesterol levels eight weeks after starting treatment (MD 0.35, 95% CI 0.27 to 0.43; one study with 112 participants). There was moderate certainty evidence suggesting no difference between the use of metformin and placebo for the outcomes of drop-outs from care (RR 1.22, 95% CI 0.09 to 16.35; three studies with 158 participants). There was moderate-to-high certainty evidence of no difference between metformin and placebo for fasting blood glucose levels (endpoint data: MD -0.35, 95% CI -0.60 to -0.11; change from baseline data: MD 0.01, 95% CI -0.21 to 0.22; five studies with 264 participants). There was high certainty evidence that BMI was lower for participants receiving metformin compared with those receiving a placebo (MD -1.37, 95% CI -2.04 to -0.70; five studies with 264 participants; high certainty of evidence). There was no difference between metformin and placebo for the outcomes of waist circumference, blood pressure and cholesterol levels. Low-certainty evidence from one study (48 participants) suggests there may be no difference between the use of melatonin and placebo for the outcome of drop-outs from care (RR 1.00, 95% CI 0.38 to 2.66). Fasting blood glucose is probably reduced more in participants treated with melatonin compared with placebo (endpoint data: MD -0.17, 95% CI -0.35 to 0.01; change from baseline data: MD -0.24, 95% CI -0.39 to -0.09; three studies with 202 participants, moderate-certainty evidence). There was no difference between melatonin and placebo for the outcomes of waist circumference, blood pressure and cholesterol levels. Very low-certainty evidence from one study (25 participants) suggests that drop-outs may be higher in participants treated with a tricyclic antidepressant (TCA) compared with those receiving a selective serotonin reuptake inhibitor (SSRI) (RR 0.34, 95% CI 0.11 to 1.01). It is uncertain if there is no difference in fasting blood glucose levels between these groups (MD -0.39, 95% CI -0.88 to 0.10; three studies with 141 participants, moderate-certainty evidence). It is uncertain if there is no difference in BMI and depression between the TCA and SSRI antidepressant groups. AUTHORS' CONCLUSIONS: Only one study reported data on our primary outcome of interest, providing low-certainty evidence that there may be no difference in risk between atypical and typical antipsychotics for the outcome of developing type 2 diabetes. We are therefore not able to draw conclusions on the prevention of type 2 diabetes in people with mental disorders in LMICs. For studies reporting on secondary outcomes, there was evidence of risk of bias in the results. There is a need for further studies with participants from LMICs with mental disorders, particularly on behaviour change and on organisational interventions targeting prevention of type 2 diabetes in these populations.

BACKGROUND: Well-functioning patient feedback systems can contribute to improved quality of healthcare and systems accountability. We used realist evaluation to examine patient feedback systems at health facilities in Bangladesh, informed by theories of citizenship and principal-agent relationships. METHODS: We collected and analysed data in two stages, using: document review; secondary analysis of data from publicly available web-portals; in-depth interviews with patients, health workers and managers; non-participant observations of feedback environments; and stakeholder workshops. Stage 1 focused on identifying and articulating the initial programme theory (PT) of patient feedback systems. In stage 2, we iteratively tested and refined this initial theory, through analysing data and grounding emerging findings within substantive theories and empirical literature, to arrive at a refined PT. RESULTS: Multiple patient feedback systems operate in Bangladesh, essentially comprising stages of collection, analysis and actions on feedback. Key contextual enablers include political commitment to accountability, whereas key constraints include limited patient awareness of feedback channels, lack of guidelines and documented processes, local political dynamics and priorities, institutional hierarchies and accountability relationships. Findings highlight that relational trust may be important for many people to exercise citizenship and providing feedback, and that appropriate policy and regulatory frameworks with clear lines of accountability are critical for ensuring effective patient feedback management within frontline healthcare facilities. CONCLUSION: Theories of citizenship and principal-agent relationships can help understand how feedback systems work through spotlighting the citizenship identity and agency, shared or competing interests, and information asymmetries. We extend the understanding of these theories by highlighting how patients, health workers and managers act as both principals and agents, and how information asymmetry and possible agency loss can be addressed. We highlight the importance of awareness raising and non-threatening environment to provide feedback, adequate support to staff to document and analyse feedback and timely actions on the information.

BACKGROUND: Antibiotic resistance is a global threat to human health, and inappropriate use of antibiotics in humans and animals is widely considered to be a key driver of antibiotic resistant infections. Antibiotic use in humans and animals is growing rapidly in low- and, particularly, middle-income countries. However, there is little detailed understanding about practices related to the use of antibiotics in humans and animals within community settings in such countries. Here we aimed to understand the antibiotic practices of rural households across Cumilla district, Bangladesh, in relation to household members and their domestic animals. METHODS: In 2018 we conducted a cross-sectional survey using representative cluster sampling methods. We collected self-reported information from 682 female and 620 male household heads, with women also asked about their children's antibiotic practices. RESULTS: Only 48% (95% CI: 40, 56%) of women and men had heard of antibiotics, and among those women and men who were aware of antibiotics and the children of those women 70% (95% CI: 64, 76%) reported having previously taken antibiotics, while among these individuals who reported previously taking antibiotics 21% (95% CI: 18, 25%) said they had done so most recently within the last month. Risky/inappropriate antibiotic practices in humans and animals were often reported. For example, among women and men who were aware of antibiotics and the children of those women 52% (95% CI: 40, 63%) reported previously taking antibiotics for a "cough/cold", despite antibiotics being typically inappropriate for use against viral upper respiratory tract infections. Among poultry-owning respondents who were aware of antibiotics 11% (95% CI: 8, 15%) reported previously giving healthy poultry antibiotics, mainly for growth/prophylaxis, while among cattle-owning respondents who were aware of antibiotics and reported previously giving their cattle feed 20% (95% CI: 9, 37%) said the feed had contained antibiotics at least sometimes. CONCLUSIONS: Our results highlight the need for context-adapted interventions at both the community level and the health systems level to reduce inappropriate antibiotic use among humans and domestic animals in rural Bangladesh. Successfully reducing inappropriate use of antibiotics among humans and animals is a required and critical step in tackling antimicrobial resistance.

Early detection of pediatric eye problems can prevent future vision loss. This study was to estimate the prevalence of common eye problems among infants born in a resource-constrained emergency setting with a broader aim to prevent future vision loss or blindness among them through early detection and referral. We conducted a cross-sectional survey among 670 infants (0-59 days old) born in Rohingya refugee camps in Bangladesh between March and June of 2019. The most common eye problem found was watering from the eye and accumulation of discharge by which 14.8% of the children were suffering (95% CI: 12.2-17.7). More than 5% of the infants had visual inattention (95% CI: 3.5-7.0), and 4% had redness in their eyes (95% CI: 2.7-5.8). Only 1.9% of infants (95% CI: 1-3.3) had whitish or brown eyeballs, and 1.8% of children might have whitish pupillary reflex (95% CI: 0.9-3.1). None of the eye problems was associated with the gender of the infants. The prevalent eye problems demand eye care set up for the screening of eye problems in the camps with proper referral and availability of referral centres with higher service in the districts.
