Frequency of use of the International Classification of Diseases ICD-10 diagnostic categories for mental and behavioural disorders across world regions.

The study aimed to examine variations in the use of International Classification of Diseases, Tenth Edition (ICD-10) diagnostic categories for mental and behavioural disorders across countries, regions and income levels using data from the online World Psychiatric Association (WPA)-World Health Organization (WHO) Global Survey that examined the attitudes of psychiatrists towards the classification of mental disorders. A survey was sent to 46 psychiatric societies which are members of WPA. A total of 4887 psychiatrists participated in the survey, which asked about their use of classification, their preferred system and the categories that were used most frequently. The majority (70.1%) of participating psychiatrists (out of 4887 psychiatrists) reported using the ICD-10 the most and using at least one diagnostic category once a week. Nine out of 44 diagnostic categories were considerably variable in terms of frequency of use across countries. These were: emotionally unstable personality disorder, borderline type; dissociative (conversion) disorder; somatoform disorders; obsessive-compulsive disorder (OCD); mental and behavioural disorders due to the use of alcohol; adjustment disorder; mental and behavioural disorders due to the use of cannabinoids; dementia in Alzheimer's disease; and acute and transient psychotic disorder. The frequency of use for these nine categories was examined across WHO regions and income levels. The most striking differences across WHO regions were found for five out of these nine categories. For dissociative (conversion) disorder, use was highest for the WHO Eastern Mediterranean Region (EMRO) and non-existent for the WHO African Region. For mental and behavioural disorders due to the use of alcohol, use was lowest for EMRO. For mental and behavioural disorders due to the use of cannabinoids, use was lowest for the WHO European Region and the WHO Western Pacific Region. For OCD and somatoform disorders, use was lowest for EMRO and the WHO Southeast Asian Region. Differences in the frequency of use across income levels were statistically significant for all categories except for mental and behavioural disorders due to the use of alcohol. The most striking variations were found for acute and transient psychotic disorder, which was reported to be more commonly used among psychiatrists from countries with lower income levels. The differences in frequency of use reported in the current study show that cross-cultural variations in psychiatric practice exist. However, whether these differences are due to the variations in prevalence, treatment-seeking behaviour and other factors, such as psychiatrist and patient characteristics as a result of culture, cannot be determined based on the findings of the study. Further research is needed to examine whether these variations are culturally determined and how that would affect the cross-cultural applicability of ICD-10 diagnostic categories.

Suicide and depression in the World Health Organization South-East Asia Region: A systematic review

Background Depression is the most common comorbid psychiatric disorder in people who die by suicide and 39% of global suicides occur in the World Health Organization (WHO) South-East Asia Region. The aim of this systematic review was to identify, for countries of this region, first the prevalence of depression among people who (i) die by, or (ii) attempt, suicide, and second, the proportion of people with depression who attempt or die by suicide. Methods PubMed, PsycINFO, EMBASE and Google Scholar were searched, together with five available national databases, for quantitative research papers published in English between 1956 and 4 September 2016 from the 11 countries of the WHO South-East Asia Region. Results The 19 articles that met the predefined eligibility criteria were from five countries: Bangladesh (1), India (12), Indonesia (1), Sri Lanka (3) and Thailand (2); no eligible papers from the remaining countries of the region were retrieved. Eight studies, from Bangladesh, India, Indonesia and Sri Lanka, reported the prevalence of depression among people who had died by suicide. The study settings varied, as did the proportion of depression recorded (6.9-51.7%), and the study sample sizes ranged from 27 to 372. Eight studies from India and one from Sri Lanka investigated depression among people who had attempted suicide. Using a range of screening and diagnostic tools, the reported prevalence of depression ranged between 22.0% and 59.7%. The study sample sizes ranged from 56 to 949. Only two articles were found, both from Thailand, that reported on suicide in people with depression. Conclusion Despite the high burden of mortality of suicide in the WHO South-East Asia Region, evidence on the relation between suicide and depression is scarce. There is a need to understand this phenomenon better, in order to inform suicide-prevention strategies in the region.

Health risks of climate change in the World Health Organization South-East Asia Region.

Countries in the World Health Organization (WHO) South-East Asia Region are particularly vulnerable to a changing climate. Changes in extreme weather events, undernutrition and the spread of infectious diseases are projected to increase the number of deaths due to climate change by 2030, indicating the need to strengthen activities for adaptation and mitigation. With support from the WHO Regional Office for South-East Asia and others, countries have started to include climate change as a key consideration in their national public health policies. Further efforts are needed to develop evidence-based responses; garner the necessary support from partner ministries; and access funding for activities related to health and climate change. National action plans for climate change generally identify health as one of their priorities; however, limited information is available on implementation processes, including which ministries and departments would be involved; the time frame; stakeholder responsibilities; and how the projects would be financed. While progress is being made, efforts are needed to increase the capacity of health systems to manage the health risks of climate change in South-East Asia, if population health is to be protected and strengthened while addressing changing weather and climate patterns. Enhancing the resilience of health systems is key to ensuring a sustainable path to improved planetary and population health.

Climate conditions, workplace heat and occupational health in South-East Asia in the context of climate change.

Occupational health is particularly affected by high heat exposures in workplaces, which will be an increasing problem as climate change progresses. People working in jobs of moderate or heavy work intensity in hot environments are at particular risk, owing to exposure to high environmental heat and internal heat production. This heat needs to be released to protect health, and such release is difficult or impossible at high temperatures and high air humidity. A range of clinical health effects can occur, and the heat-related physical exhaustion leads to a reduction of work capacity and labour productivity, which may cause substantial economic losses. Current trends in countries of the World Health Organization South-East Asia Region are towards higher ambient heat levels during large parts of each year, and modelling indicates continuing trends, which will particularly affect low-income individuals and communities. Prevention activities need to address the climate policies of each country, and to apply currently available heat-reducing technologies in workplaces whenever possible. Work activities can be adjusted to reduce exposure to daily heat peaks or seasonal heat concerns. Application of basic occupational health principles, such as supply of drinking water, enforcement of rest periods and training of workers and supervisors, is essential.

Water, sanitation and hygiene: The unfinished agenda in the World Health Organization South-East Asia Region.

Access to adequate water, sanitation and hygiene (WASH) is essential for the health, well-being and dignity of all people. The World Health Organization South-East Asia Region has made considerable progress in WASH provision during the past two decades. However, compared with increases in coverage of improved drinking water, in some parts of the region, access to adequate sanitation remains low, with continued prevalence of open defecation. The Sustainable Development Goals (SDGs) have set ambitious targets for WASH services to be achieved by 2030. Examples of major health outcomes that would benefit from meeting these targets are diarrhoea and nutrition status. Although the total number of deaths attributable to diarrhoea declined substantially between 1990 and 2012, inadequate WASH still accounts for more than 1000 child deaths each day worldwide. And, despite the reductions in mortality, diarrhoea morbidity attributable to diarrhoea remains unchanged at around 1.7 billion cases per year. It has been known for decades that repeated episodes of diarrhoea increase a child's risk of long-term undernutrition, reduced growth and impaired cognitive development. Nutritional effects of inadequate WASH also include environmental enteropathy, leading to chronic intestinal inflammation, malnutrition and developmental deficits in young children. Inadequate WASH also contributes to iron deficiency anaemia resulting from infestation with soil-transmitted helminths. The cross-sectoral emphasis of the SDGs should act as a stimulus for intersectoral collaboration on research and interventions to reduce all inequities that result from inadequate WASH.

Vigilance to Limit the Bidirectional Introduction and Co-circulation of Virus Serotypes Aims to Reduce Risk of Severe Dengue Disease in North East India

Dengue is a serious re-emerging arboviral disease that presents a global human health challenge. Infection is caused by one of several recognised serotypes of dengue virus, a member of the mosquito-transmitted Flaviviridae family of human pathogens, which also includes yellow fever, Zika and West Nile viruses. The greatest burden of dengue is borne by countries in the Asia Pacific region, in particular South East Asia and the Indian subcontinent where infection breaks out with increasing frequency and intensity. The World Health Organization South East Asia Region has a population of 1.3 billion people and includes 11 countries, of which Thailand, Myanmar and India have the highest reported incidence of dengue. Infection outcomes vary from the commonly asymptomatic or a self-limiting fever to more severe manifestations such as dengue haemorrhagic fever and dengue shock syndrome. Although primary infection with one serotype elicits lifelong immunity against homologous reinfection, severe dengue is linked to an antibody-related immunopathological response that is triggered by secondary infection with a heterologous serotype. The principal vectors of transmission are the day-biting mosquitoes Aedes aegypti and Ae. albopictus, the respective preference of which for urban and rural habitats has facilitated the rapid and continued spread of dengue across tropical and sub-tropical climatic zones. The narrow elevated corridor of North East India was considered historically to be non-endemic for dengue and as such separated areas of high endemicity in the Bengal Delta and the other zones of India from those in Thailand and Myanmar. In these regions the predominant serotype is usually distinct, so a breach of this geographical bottleneck would potentially enable the co-circulation of virus serotypes, thus posing an increased risk of severe disease upon secondary infection. This alarming scenario may now be realized following the notification of clinical cases in the states of Arunachal Pradesh, Assam and Manipur in recent years. While incidence is still sporadic in North East India limitation of local outbreaks is required through vigilant adherence to the integrated implementation of clinical management, diagnosis, surveillance and vector control in order to prevent the transcontinental spread of dengue.

Population-based dietary approaches for the prevention of noncommunicable diseases.

As the incidence of noncommunicable diseases such as diabetes continues to rise at an alarming rate in South-East Asia, it is imperative that urgent and population-wide strategies are adopted. The most important contributors to the rise in noncommunicable disease are a rise in mean caloric intake and a decrease in physical activity. The evidence for population-based dietary approaches to counter these factors is reviewed. Several structural and cohesive interdepartmental coordination efforts are required for effective implementation of prevention strategies. Since low- and middle-income countries may lack the frameworks for effective and integrated multi-stakeholder intervention, implementation of population-based dietary and physical-activity approaches may be delayed and may be too late for effective prevention in current at-risk cohorts. Evidence-based strategies to decrease energy intake and increase physical activity are now well established and their urgent adoption by Member States of the World Health Organization South-East Asia Region is essential. In the context of Sri Lanka, for example, it is recommended that the most effective and easy-to-implement interventions would be media campaigns, restrictions on advertisement of unhealthy foods, taxation of unhealthy foods, subsidies for production of healthy foods, and laws on nutrition labelling that introduce colour coding of packaged foods.

Sri Lanka takes action towards a target of zero rabies death by 2020.

Rabies is a 100% vaccine-preventable and 100% fatal zoonotic, viral disease. It is usually spread to humans by saliva, through bites or scratches. Dogs are the source of the vast majority of human deaths from rabies. Political will and leadership have been the main drivers for success of the Sri Lankan effort to reduce the burden of disease attributable to rabies. Post-exposure prophylaxis, which is available in government health facilities, at no cost, to all bite patients, has been a main axis of the rabies-elimination strategy. To attain the last mile in rabies elimination in Sri Lanka by 2020, more will need to be done to scale up dog vaccination, enforce responsible dog ownership, strengthen surveillance for animals and humans and conduct mass awareness programmes. Sri Lanka is the first country in the World Health Organization South-East Asia Region to develop a national strategy for elimination of dog-mediated rabies and is a key country in sharing knowledge, expertise and capacity-building in the region, towards a global target of zero rabies deaths by 2030.

Slowing the diabetes epidemic in the World Health Organization South-East Asia Region: the role of diet and physical activity.

The nutrition transition occurring in the World Health Organization South-East Asia Region, as a result of rapid urbanization and economic development, has perhaps made this region one of the epicentres of the diabetes epidemic. This review attempts to evaluate the role of diet and physical inactivity in the South-East Asia Region in promoting this epidemic and points to strategies to slow it down by lifestyle modification. The emerging new food-production technologies and supermarkets have made energy-dense foods more easily available. This includes refined carbohydrate foods like those with added sugars, and refined grains and unhealthy fats. In addition, increased availability of modern technology and motorized transport has led to decreased physical activity. South Asian diets tend to be based on high-carbohydrate foods, with a predominance of refined grains. All of these accentuate the risk of diabetes in people of this region, who already have a unique "south Asian phenotype". However, there is increasing evidence that altering diet by replacing refined cereals like white rice with whole grains (e.g. brown rice) and increasing physical activity can help to prevent diabetes in high-risk individuals. An urgent, concerted effort is now needed to improve diet quality and encourage physical activity, by introducing changes in policies related to food and built environments, and improving health systems to tackle noncommunicable diseases like diabetes.

Commitment of measles elimination by 2020: challenges in India.

The eleven member states of World Health Organization South-East Asia Region committed to eliminate measles by 2020. In phased manner, Government of India is working on this goal, and has introduced two-dose strategy for measles vaccine in the routine immunization. Molecular epidemiology of measles in India has been considerably growing that would be useful for understanding the circulation of wild type measles in pre- and post-elimination period. However, importations of cases from other countries may be likely. This article describes major challenges to achieve the measles elimination goal in India.

A review of the Sri Lankan health-sector response to intimate partner violence: looking back, moving forward.

Intimate partner violence (IPV) is a major health concern for women worldwide. Prevalence rates for IPV are high in the World Health Organization South-East Asia Region, but little is known about health-sector responses in this area. Health-care professionals can play an important role in supporting women who are seeking recourse from IPV. A comprehensive search was conducted to identify relevant published and grey literature over the last 35 years that focused on IPV, partner/ spousal violence, wife beating/abuse/battering, domestic violence, and Sri Lanka. Much of the information about current health-sector response to IPV in Sri Lanka was not reported in published and grey literature. Therefore, key personnel from the Ministry of Health, hospitals, universities and nongovernmental organizations were also interviewed to gain additional, accurate and timely information. It was found that the health-sector response to IPV in Sri Lanka is evolving, and consists of two models of service provision: (i) gender based violence desks, which integrate selective services at the provider/facility level; and (ii) Mithuru Piyasa (Friendly Abode) service points, which integrate comprehensive services at the provider/facility level and some at the system level. This paper presents each model's strengths and limitations in providing comprehensive and integrated health services for women who experience IPV in the Sri Lankan context.

Update on polio eradication in the World Health Organization South-East Asia Region, 2013.

There has been a tremendous amount of progress toward polio eradication in the World Health Organization South-East Asia Region particularly over the past 4 years. In 1988, there were >25,000 reported cases of wild poliovirus infection in the South-East Asia Region, and because of substantial underreporting the estimated polio burden was probably 10-fold higher. Following the initiation of mass polio immunization campaigns in the mid-1990s and years of intense effort, the 11 countries of the South-East Asia Region reported no cases of wild poliovirus infection in 2012. With India reporting the last wild poliovirus case in the region, on 13 January 2011, and its subsequent removal from the list of polio-endemic countries, in February 2012, the South-East Asia Region is firmly on track for polio-free certification in early 2014.

The long winding road of opioid substitution therapy implementation in South-East Asia: challenges to scale up.

The South-East Asia Region contains an estimated 400,000-500,000 people who inject drugs (PWID). HIV prevalence among PWID is commonly 20% or higher in Indonesia, Thailand, Myanmar and some regions of India. Opioid substitution therapy (OST) is an important HIV prevention intervention in this part of the world. However, key challenges and barriers to scale up of OST exist, including: pervasive stigma and discrimination towards PWID; criminalisation of drug use overshadowing a public health response; lack of political will and national commitment; low financial investment; focus towards traditional treatment models of detoxification and rehabilitation; inadequate dosing of OST; and poor monitoring and evaluation of programmes. Our review of local evidence highlights that OST can be successful within the Asian context. Such evidence should be utilised more widely to advocate for policy change and increased political commitment to ensure OST reaches substantially more drug users.Significance for public healthSeveral countries in the World Health Organization South-East Asia Region can be commended for introducing opioid substitution therapy (OST) to address the ongoing HIV epidemic among people who inject drugs (PWID). Local evidence shows OST is an effective drug treatment approach in the Asian context given sufficient technical and institutional support. However, despite much progress, the number of OST dispensing sites and recipients remains totally inadequate in terms of impact upon the current HIV epidemic among PWID. Ongoing advocacy is needed if countries are to achieve the WHO’s target of 40% of PWID being dosed with OST. Greater political commitment a strengthened policy environment, capacity building for OST clinics, lessening the criminalisation of drug use and promoting a public health response will give many more PWID access to OST and slow the advance of the HIV epidemic.

Indonesia: An Emerging Market Economy Beset by Neglected Tropical Diseases (NTDs)

Despite an enormous population and growing economy, the nation of Indonesia has some of the world's highest concentrations of neglected tropical diseases (NTDs). These NTDs may thwart future national growth and recent gains. Yet, Indonesia and its Ministry of Health, together with the World Health Organization (WHO), have embarked on an ambitious effort to quickly assemble a health and scientific infrastructure suitable for eliminating its NTDs. The nation of Indonesia is the world's largest island nation (approximately 17,000 islands of which 5,000–6,000 are inhabited) and the fourth most populated nation behind China, India, and the United States (Figure 1) [1]. The nation is tied with the Netherlands as the world's 16th largest economy [1]. According to the World Bank, Indonesia together with South Korea and the BRIC (Brazil, Russia, India, and China) countries will account for more than half of the world's economic growth by 2025 [2]. Figure 1 Map of Indonesia. Despite the future promise of these economic gains, Indonesia is also simultaneously hobbled by a staggering level of extreme poverty. According to the World Bank, of Indonesia's estimated population of 242 million [3], an estimated 46% (approximately 111 million people) live on less than $2 per day [4], while 18% (44 million people) live on less than $1.25 per day [5]. Today, one of the most potent forces that currently traps Indonesia's poorest 111 million people in poverty and could eventually threaten Indonesia's economic potential is a group of NTDs affecting the region. The NTDs are chronic conditions with clinical features similar to many noncommunicable diseases [6]. When they become widespread [6], these diseases have the ability to thwart or stall economies because of their adverse impact on child development, labor, and the health of girls and women [7]. Indeed, Indonesia's “bottom 111” million suffer from an extraordinary level of NTDs, led by widespread helminth infections, such as soil-transmitted helminth (STH) infections and lymphatic filariasis (LF), and neglected bacterial infections, such as yaws and leptospirosis (Table 1) [8]. Moreover, Indonesia is the only country in the WHO's South-East Asia Region with endemic schistosomiasis [8] (the other Asian countries with endemic schistosomiasis are in WHO's Western Pacific region), and the nation is facing a serious and emerging threat from dengue fever [9]. Table 1 The major neglected tropical diseases of Indonesia.

Health spending, macroeconomics and fiscal space in countries of the World Health Organization South-East Asia Region

The paper examines the issues around mobilization of resources for the 11 countries of the South-East Asia Region of the World Health Organization (WHO), by analysing their macroeconomic situation, health spending, fiscal space and other determinants of health. With the exception of a few, most of these countries have made fair progress on their own Millennium Development Goal (MDG) targets of maternal mortality ratio and mortality rate in children aged under 5 years. However, the achieved targets have been very modest - with the exception of Thailand and Sri Lanka - indicating the continued need for additional efforts to improve these indicators. The paper discusses the need for investment, by looking at evidence on economic growth, the availability of fiscal space, and improvements in "macroeconomic-plus" factors like poverty, female literacy, governance and efficiency of the health sector. The analysis indicates that, overall, the countries of the WHO South-East Asia Region are collectively in a position to make the transition from low public spending to moderate or even high health spending, which is required, in turn, for transition from lowcoverage-high out-of-pocket spending (OOPS) to highcoverage-low OOPS. However, explicit prioritization for health within the overall government budget for low spenders would require political will and champions who can argue the case of the health sector. Additional innovative avenues of raising resources, such as earmarked taxes or a health levy can be considered in countries with good macroeconomic fundamentals. With the exception of Thailand, this is applicable for all the countries of the region. However, countries with adverse macroeconomic-plus factors, as well as inefficient health systems, need to be alert to the possibility of overinvesting - and thereby wasting - resources for modest health gains, making the challenge of increasing health sector spending alongside competing demands for spending on other areas of the social sector difficult.

Levels and trends of smokeless tobacco use among youth in countries of the World Health Organization South-East Asia Region.

At least two rounds of the Global Youth Tobacco Survey (GYTS) have been completed in most of the countries in the World Health Organization South-East Asia region. Comparing findings from these two rounds provides trend data on smokeless tobacco (SLT) use for the first time. This study uses GYTS data from Bangladesh, Bhutan, India, Indonesia, Maldives, Myanmar, Nepal, Sri Lanka, Thailand, and Timor-Leste during 2006-2013. GYTS is a nationally representative survey of 13-15-year-old students using a consistent and standard protocol. Current SLT use is defined as using any kind of SLT products, such as chewing betel quid or nonbetel quid or snuffing any other products orally or through the nasal route, during the 30 days preceding the survey. Prevalence and 95% confidence intervals were computed using SAS/SUDAAN software. According to most recent GYTS data available in each country, the prevalence of current use of SLT among youth varied from 5.7% in Thailand to 23.2% in Bhutan; among boys, from 7.1% in Bangladesh to 27.2% in Bhutan; and among girls, from 3.7% in Bangladesh to 19.8% in Bhutan. Prevalence of SLT was reported significantly higher among boys than girls in Bhutan (boys 27.2%; girls 19.8%), India (boys 11.1%; girls 6.0%), Maldives (boys 9.2%; girls 2.9%), Myanmar (boys 15.2%; girls 4.0%), and Sri Lanka (boys 13.0%; girls 4.1%). Prevalence of current SLT use increased in Bhutan from 9.4% in 2009 to 23.2% in 2013, and in Nepal from 6.1% in 2007 to 16.2% in 2011. The findings call for countries to implement corrective measures through strengthened policy and enforcement.

Prevalence and sociodemographic determinants of tobacco use in four countries of the World Health Organization: South-East Asia region: findings from the Global Adult Tobacco Survey.

Tobacco use is a leading cause of deaths and Disability Adjusted Life Years lost worldwide, particularly in South-East Asia. Health risks associated with exclusive use of one form of tobacco alone has a different health risk profile when compared to dual use. In order to tease out specific profiles of mutually exclusive categories of tobacco use, we carried out this analysis. The Global Adult Tobacco Survey (GATS) data was used to describe the profiles of three mutually exclusive tobacco use categories ("Current smoking only," "Current smokeless tobacco [SLT] use only," and "Dual use") in four World Health Organization South-East Asia Region countries, namely Bangladesh, India, Indonesia and Thailand. GATS was a nationally representative household-based survey that used a stratified multistage cluster sampling design proportional to population size. Prevalence of different forms of usage were described as proportions. Logistics regression analyses was performed to calculate odds ratios (OR) with 95% confidence intervals. All analyses were weighted, accounted for the complex sampling design and conducted using SPSS version 18. The prevalence of different forms of tobacco use varied across countries. Current tobacco use ranged from 27.2% in Thailand to 43.3% in Bangladesh. Exclusively smoking was more common in Indonesia (34.0%) and Thailand (23.4%) and less common in Bangladesh (16.1%) and India (8.7%). Exclusively using SLT was more common in Bangladesh (20.3%) and India (20.6%) and less common on Indonesia (0.9%) and Thailand (3.5%). Dual use of smoking and SLT was found in Bangladesh (6.8%) and India (5.3%), but was negligible in Indonesia (0.8) and Thailand (0.4%). Gender, age, education and wealth had significant effects on the OR for most forms of tobacco use across all four countries with the exceptions of SLT use in Indonesia and dual use in both Indonesia and Thailand. In general, the different forms of tobacco use increased among males and with increasing age; and decreased with higher education and wealth. The results for urban versus rural residence were mixed and frequently not significant once controlling for the other demographic factors. This study addressed the socioeconomic disparities, which underlie health inequities due to tobacco use. Tobacco control activities in these countries should take in account local cultural, social and demographic factors for successful implementation.

Profile of dengue infection in Jamnagar city and district, west India.

Background and Methods India is one of the countries in the World Health Organization South-East Asia Region that regularly reports outbreaks of dengue fever (DF)/dengue hemorrhagic fever (DHF). As effective control and preventive programmes depend upon improved surveillance data, this study was carried out to report the seroprevalence of dengue virus infection in an area around Jamnagar city, Western India. [1] Methods The laboratory records of clinically suspected dengue patients from July 2008 to June 2011 were analysed retrospectively for the results of immunoglobulin M (IgM) anti-dengue antibodies, tested by dengue monoclonal antibody (IgM) capture enzyme-linked immunosorbent assay (MAC ELISA). Variations in disease incidence by sex, age group and season were assessed. Results A total of 903 serum samples were tested, of which 253 were positive. The majority were males (72%) and in the age group of 16-30 years. The incidence of dengue peaked in October and slowly tapered by December. Conclusion Dengue cases were higher during September to December, in the post-monsoon season. This observation is useful for planning special preventive strategies. The study draws attention to the susceptibility of the male, young adult age group.

External quality assessment in blood group serology in the World Health Organization South-East Asia Region.

The quality of blood transfusion services (BTS) is essential for the treatment of patients who need blood or blood products. BTS involve several steps, including the acquisition of the donor's blood, blood grouping, unexpected antibody screening, blood storage, transfusion, etc. There is a need to check the effectiveness of all elements in the BTS can be assessed and monitored by an external quality assessment. To assess and evaluate the performance of ABO and Rh(D) blood grouping and unexpected antibody screening of the selected World Health Organization (WHO) South-East Asia Region Member country laboratories. WHO Collaborating Centre on Strengthening Quality of Health Laboratories (Thailand) organized a regional external quality assessment scheme for blood group serology (REQAS-BGS) between 2002 and 2008 for laboratories in countries of the WHO South-East Asia Region. Test items for ABO and Rh(D) blood groupings and unexpected antibody screening and identification were distributed three cycles per year to BTS laboratories in Bangladesh, Bhutan, India, Indonesia, Maldives, Myanmar, Nepal, Sri Lanka and Thailand. By the end of the project, a total of 20 BTS laboratories had participated for differing lengths of time. It was found that 87.5%, 93.3%, 81.3%, 92.3%, 100% and 87.5% of laboratories returned the test results in 2002, 2003, 2004, 2006, 2007 and 2008, respectively. Laboratories with excellent quality or a trend of quality improvement for ABO and Rh(D) blood grouping, unexpected antibody screening and identification during the six years were 60% (12/20), 50% (10/20), 52.9% (9/17) and 81.8% (9/11), respectively. At the initiation of the scheme, most laboratories were using substandard methods for ABO and Rh blood groupings, i.e. performing only direct blood grouping alone but subsequently adopted the standard methods, i.e. performing both direct and reverse blood groupings. REQAS-BGS in South-East Asia countries has been useful for assessing, monitoring and improving the quality of testing. Challenges such as high costs and regulatory requirements for international shipment of blood samples could be solved by amending the regulation(s) for shipment, or establishing a national EQAS.

Trend of Tobacco Use and Exposure to Secondhand Smoke Among Students Aged 13-15 Years in India and Selected Countries of the South-East Asia Region

Trend of Tobacco Use and Exposure to Secondhand Smoke Among Students Aged 13-15 Years in India and Selected Countries of the South-East Asia Region
