Addressing Unintentional Exclusion of Vulnerable and Mobile Households in Traditional Surveys in Kathmandu, Dhaka, and Hanoi: a Mixed-Methods Feasibility Study.

The methods used in low- and middle-income countries' (LMICs) household surveys have not changed in four decades; however, LMIC societies have changed substantially and now face unprecedented rates of urbanization and urbanization of poverty. This mismatch may result in unintentional exclusion of vulnerable and mobile urban populations. We compare three survey method innovations with standard survey methods in Kathmandu, Dhaka, and Hanoi and summarize feasibility of our innovative methods in terms of time, cost, skill requirements, and experiences. We used descriptive statistics and regression techniques to compare respondent characteristics in samples drawn with innovative versus standard survey designs and household definitions, adjusting for sample probability weights and clustering. Feasibility of innovative methods was evaluated using a thematic framework analysis of focus group discussions with survey field staff, and via survey planner budgets. We found that a common household definition excluded single adults (46.9%) and migrant-headed households (6.7%), as well as non-married (8.5%), unemployed (10.5%), disabled (9.3%), and studying adults (14.3%). Further, standard two-stage sampling resulted in fewer single adult and non-family households than an innovative area-microcensus design; however, two-stage sampling resulted in more tent and shack dwellers. Our survey innovations provided good value for money, and field staff experiences were neutral or positive. Staff recommended streamlining field tools and pairing technical and survey content experts during fieldwork. This evidence of exclusion of vulnerable and mobile urban populations in LMIC household surveys is deeply concerning and underscores the need to modernize survey methods and practices.

Epidemiology of childhood blindness: A community-based study in Bangladesh.

This study aimed to investigate the prevalence and causes of childhood blindness in a rural area of Bangladesh. We adopted a cross-sectional quantitative study design for this study, which was performed in three unions (sub-districts) located in Raiganj Upazila of the Sirajganj district in Bangladesh. Using a validated tool, a screening program was conducted at the household level. After initial screening, a team of ophthalmologists confirmed the diagnoses by clinical examinations. The prevalence of childhood blindness was observed to be 6.3 per 10,000 children, whereas the rate of uniocular blindness was 4.8 per 10,000 children. Congenital problems were the major causes of both uniocular and binocular blindness (uniocular blindness: 84% and binocular blindness: 92%). The whole globe was the site responsible for binocular blindness (28.0%, 95% confidence interval [CI]: 13.1, 47.7), whereas the cornea was responsible for uniocular blindness (57.8%, 95% CI: 35.3, 78.1). Childhood blindness is a public health problem in Bangladesh and is highly prevalent, regardless of sex. The major causes of childhood blindness are congenital.

Alarming rise in fatal electrocutions in Bangladesh: Comparison of two national surveys.

BACKGROUND AND OBJECTIVES: Electrical injuries are major contributor to burn-related mortality and morbidity. Mortality data were compared from the two largest community-based health and injury surveys in Bangladesh conducted thirteen years apart to investigate the changes in epidemiological features of this adverse health event. METHODS: The nationwide Bangladesh Health and injury surveys (BHIS) were conducted among 819,429 people in 2003 and 299,216 in 2016 using a pretested semi-structured questionnaire at the household level. History of electrocution death events in previous one year in the household was determined by verbal autopsy method in both surveys. Thus, each survey result represents the scenario of the year before. Descriptive and comparative analysis was done to investigate the changes in the distribution of electrocution deaths. RESULTS: The incidence of electrocution deaths was 1.7 and 4.3 per 100,000 population respectively in the 2003 and 2016 survey. The majority of the cases were aged between 18 to 59 years in both years. The comparison of the two survey results shows that the death rates increased in every age group those were examined. The rates were persistently higher in rural areas compared to the urban. Moreover, the rural mortality rate increased strikingly in 2015. The highest proportion of fatal electrocution events occurred at workplaces and males had a higher mortality rate in contrast to females in both the surveys. The death rate in males doubled in 2015 (6.0 per 100,000) from 2002 rate (3.1 per 100,000). CONCLUSION: Electrocution mortality rates have raisen alarmingly between 2002 and 2015. Working persons and males have a higher susceptibility to deaths from electrocution. Rural areas pose greater threats compared to urban Bangladesh. Being derived from a nationwide survey, these facts provide with useful direction to set priorities for prevention of this emerging unnatural cause of death in the country.

Social autopsy for maternal and perinatal deaths in Bangladesh: a tool for community dialog and decision making.

Bangladesh has an established comprehensive death review system for tracking and reviewing maternal and perinatal deaths. This death review system, established in 2010, was initially known as the "Maternal and Perinatal Death Review (MPDR) System." One of the key interventions of the MPDR system, social autopsy (SA), is generally undertaken following a maternal or perinatal death notification. Social autopsy is managed at the community level by government field health workers. The main purpose of SA is to enable community discussion and create awareness of the preventable causes of maternal or neonatal deaths. Through these conversations, it is hoped to reduce future maternal and neonatal deaths. During the scaling up of the system in Bangladesh in 2016, the Ministry of Health and Family Welfare (MoH&FW) included social autopsy as a useful intervention in reviewing death at the community level and named it "Maternal and Perinatal Death Surveillance and Response" (MPDSR). The new MPDSR tool is currently being administered for the the 2017 to 2021 period under the National Health and Nutrition Population Sector Program (HPNSP). This paper seeks to review the experiences of the social autopsy tool, from the initial MPDR system to the current MPDSR system and its role in reducing maternal and neonatal deaths in Bangladesh.

Changes in burn mortality in Bangladesh: Findings from Bangladesh Health and Injury Survey (BHIS) 2003 and 2016.

PURPOSE: This paper is focused to reflect the changes in burn mortality and events leading to fatal burn injuries. METHODS: Two national community-based cross sectional health and injury surveys were done in Bangladesh during 2003 and 2016. Similar methodology had been followed in both the surveys. Multistage cluster sampling method considering probability-proportional-to-size strategy was used in both the surveys to obtain the desired sample. A pretested semi-structured questionnaire was deployed to identify causes of mortality and morbidity among the population. Verbal autopsy method was used to ascertain the cause of death. RESULTS: An estimated 5000 deaths occurred during 2002 due to burn, whereas, around 9000 deaths were caused by burn in 2015 reflected by the death rates 3.5 and 5.7 per 100,000 population in respective years. This study found an increase in death rates in all age groups from 2002 to 2015. Electrocution caused the highest burn deaths in this country, especially among males and in rural areas. The death toll by this particular mechanism has increased by more than two folds within a decade. The place of occurrence of fatal burn injuries has also shifted from home to the outside of the home especially in the agricultural fields. CONCLUSION: Burn death is an emerging cause of injury deaths in Bangladesh. Further researches are required to explore the epidemiology of electrocution deaths in Bangladesh and design effective interventions.

Improving household surveys and use of data to address health inequities in three Asian cities: protocol for the Surveys for Urban Equity (SUE) mixed methods and feasibility study.

INTRODUCTION: As rapid urbanisation transforms the sociodemographic structures within cities, standard survey methods, which have remained unchanged for many years, under-represent the urban poorest. This leads to an overly positive picture of urban health, distorting appropriate allocation of resources between rural and urban and within urban areas. Here, we present a protocol for our study which (i) tests novel methods to improve representation of urban populations in household surveys and measure mental health and injuries, (ii) explores urban poverty and compares measures of poverty and 'slumness' and (iii) works with city authorities to understand, and potentially improve, utilisation of data on urban health for planning more equitable services. METHODS AND ANALYSIS: We will conduct household surveys in Kathmandu, Hanoi and Dhaka to test novel methods: (i) gridded population sampling; (ii) enumeration using open-access online maps and (iii) one-stage versus two-stage cluster sampling. We will test reliability of an observational tool to categorise neighbourhoods as slum areas. Within the survey, we will assess the appropriateness of a short set of questions to measure depression and injuries. Questionnaire data will also be used to compare asset-based, consumption-based and income-based measures of poverty. Participatory methods will identify perceptions of wealth in two communities in each city. The analysis will combine quantitative and qualitative findings to recommend appropriate measures of poverty in urban areas. We will conduct qualitative interviews and establish communities of practice with government staff in each city on use of data for planning. Framework approach will be used to analyse qualitative data allowing comparison across city settings. ETHICS AND DISSEMINATION: Ethical approvals have been granted by ethics committees from the UK, Nepal, Bangladesh and Vietnam. Findings will be disseminated through conference papers, peer-reviewed open access articles and workshops with policy-makers and survey experts in Kathmandu, Hanoi and Dhaka.
