Item Health situation in the South-East Asia Region: challenges for the next decade(WHO Regional Office for South-East Asia, 2012-02) Plianbangchang, Samlee; Narain, Jai PItem Pandemic influenza H1N1 2009 in Thailand(WHO Regional Office for South-East Asia, 2012-02) Meeyai, Aronrag; Cooper, Ben; Coker, Richard; Pan-ngum, Wirichada; Akarasewi, Pasakorn; Iamsirithaworn, SoponBackground: Developing a quantitative understanding of pandemic influenza dynamics in South-East Asia is important for informing future pandemic planning. Hence, transmission dynamics of influenza A/H1N1 were determined across space and time in Thailand. Methods: Dates of symptom onset were obtained for all daily laboratory-confirmed cases of influenza A/H1N1pdm in Thailand from 3 May 2009 to 26 December 2010 for four different geographic regions (Central, North, North-East, and South). These data were analysed using a probabilistic epidemic reconstruction, and estimates of the effective reproduction number, R(t), were derived by region and over time. Results: Estimated R(t) values for the first wave peaked at 1.54 (95% CI: 1.42-1.71) in the Central region and 1.64 (95% CI: 1.38-1.92) in the North, whilst the corresponding values in the North-East and the South were 1.30 (95% CI: 1.17-1.46) and 1.39 (95% CI: 1.32-1.45) respectively. As the R(t) in the Central region fell below one, the value of R(t) in the rest of Thailand increased above one. R(t) was above one for 30 days continuously through the first wave in all regions of Thailand. During the second wave R(t) was only marginally above one in all regions except the South. Conclusions: In Thailand, the value of R(t) varied by region in the two pandemic waves. Higher R(t) estimates were found in Central and Northern regions in the first wave. Knowledge of regional variation in transmission potential is needed for predicting the course of future pandemics and for analysing the potential impact of control measures.Item The pattern of psychiatric admissions in a referral hospital, Bhutan(WHO Regional Office for South-East Asia, 2012-02) Pelzang, RinchenBackground: Mental illnesses are becoming a public health issue in all countries. However, data in most of the developing countries including Bhutan are scarce. This study aimed to explore the trends of admissions in the psychiatric ward of a referral hospital in Thimphu city of Bhutan. Method: The study employed a retrospective analysis method. The data were obtained from the patient admission register of the psychiatric ward to capture distribution by age, gender, occupation, nationality, clinical diagnosis, and length of stay in the ward. International Classification of Diseases (ICD) 10th Revision was used for classification of the diseases. Descriptive statistics were used to describe the pattern of patient admissions. Demographic characteristics of the sample were crosstabulated with clinical diagnosis and chi-square test was used to test statistical significance. Results: In the psychiatric ward 1336 patients were admitted over a seven-year period. In 2004- 05, 127 patients were admitted, which increased to 376 in 2010-11. Higher numbers of males (64.1%, 856) were admitted than females (35.9%, 480). Mental and behavioural disorders due to psychoactive substance use were the most common (45.5%) reason for admission. Among the admitted patients, 18.8% had no job or were dependents. A large number of patients were from Thimphu District (10.8%) and 42% of the patients stayed for one to two weeks in the hospital. Conclusions: Psychiatric admissions were found to be increasing every year. Alcohol and drug use disorders were the most frequent diagnosis leading to hospitalization. Attention must be paid to increasing the in-patient services for psychiatric patients.Item Responding to measles outbreak: closing the immunity gap in children of Timor-Leste(WHO Regional Office for South-East Asia, 2012-02) Martins, Nelson; Varkey, Sherin; Yuwono, Sidharta; Freitas, Carlitos; Cunha, Mateus; Silva, Joao D; Docarmo, AderitoBackground: An outbreak of measles was reported in Timor-Leste during 2011. A concerted response at national level utilized this opportunity to improve measles immunization coverage rates. Methods: Health Management Information System and Surveillance System data were utilized to describe the outbreak. Attack rates and case fatality rates (CFR) were calculated using standard methods. Evaluation surveys were used to access immunization coverage. Proceedings of weekly meetings of the National Committee for Control of Disease Outbreaks were reviewed. Results: A total of 739 cases and 8 deaths were reported to the Surveillance Unit. Most (>82%) of the measles cases were reported from Dili and Ermera districts. The attack rate was 1.3 per 1000 population and CFR was 1.1%. The response was coordinated by the National Committee for Control of Disease Outbreaks, which included case management, active and passive surveillance,communication and measles immunization among six-month to 14-year old children. Immunization activity targeted 495 000 children, i.e. almost one-half of the Timor-Leste population and achieved high coverage (85%). Conclusions: The outbreak highlighted gaps in the immunity against measles. The National Committee for Control of Disease Outbreaks ensured a coordinated response which led to prevention of deaths from measles due to early case management with vitamin A supplementation, and high measles immunization coverage.Item Primary health care: perspective of village women from Himachal Pradesh(WHO Regional Office for South-East Asia, 2012-02) Mazta, Salig R; Thakur, AnitaItem Behavioural risk factors of men associated with transmission of sexually transmitted infections (STIs) in Sri Lanka(WHO Regional Office for South-East Asia, 2012-02) Jayawardena, Kuruppu AS; Silva, Kalinga T; Jayawardena, Chantha K; Samarakoon, SujathaBackground: Unprotected sex is a major risk factor for transmission of sexually transmitted infections (STIs). We explored the behavioural risk factors for STIs among men who presented with STI-related symptoms. Methods: A systematic sample of 112 males presenting with STI symptoms at district sexually transmitted disease (STD) clinic located in Kandy, Sri Lanka were enrolled during 2009. They were interviewed using a semi-structured questionnaire. Selected sexual behaviours were discussed with them in greater detail. The chi-square and difference-in-two-proportion tests were used for testing the statistical significance for quantitative data, and qualitative methods were used for the analysis of responses to open-ended questions and in-depth discussion. Results: The median age of the respondents was 28 years. The majority of them (56%) had never been married. The median age at the first sexual intercourse was 22 years. The majority(87%) of respondents had their first intercourse before marriage; mostly with older females. Most (103, 92%) men reported having sexual intercourse during the past six months; of them, 40.8% had sex with multiple partners. Only 18.5% used condoms at the first premarital intercourse. The consistent use of condoms with non-marital partners during the past six months was only 13.7%. Common reasons for non-use of condoms were: belief that partner was faithful; poor knowledge about risk of unprotected sex; view that condoms reduce pleasure and negatively affect intimacy; and inhibition in accessing condoms in public. Conclusions: Sexual behaviours were found to be risky among men attending STD clinics in Sri Lanka. Strategies of sexual health promotion among vulnarable groups should be evaluated for planning proper interventions.Item From Alma-Ata to Rio: health for all to all for equity(WHO Regional Office for South-East Asia, 2012-02) Narayan, Ravi; Narayan, ThelmaItem Oral fluid therapy of cholera among Bangladesh refugees(WHO Regional Office for South-East Asia, 2012-02) Mahalanabis, D; Choudhuri, AB; Bagchi, NG; Bhattacharya, AK; Simpson, TWItem Impact of climate change on health and strategies for mitigation and adaptation(WHO Regional Office for South-East Asia, 2012-02) Deb, Alok KClimate change and its negative impacts on health are now globally recognized. A wide variety of diseases and health conditions – ranging from heat and radiation-related illnesses to water and vector-borne diseases, under-nutrition, respiratory and cardiac problems, drowning, injuries and mental stress arising from extreme and sudden weather events and their resultant population displacements – all have been associated with various components of changing climate. However,the exact nature and extent of such impacts are yet to be firmly established since many other non-climate factors also produce or affect similar outcomes. This calls for more research specially from the underdeveloped countries, where such impacts are disproportionately more but reliable data are remarkably less. Recognizing the importance of human influences on global warming,almost all countries in the world have undertaken some kind of policies and measures to mitigate adverse climatic changes. Unfortunately, even without further addition of greenhouse gases (GHGs)in our climate, the amount of GHGs already released has the potential to continue the damages for many more decades to come. Thus, all countries should also place priorities in assessing their own vulnerabilities from climate change and take adaptive measures accordingly. As climate change exerts its impact simultaneously in many non-health sectors as well, this would require strong intersectoral cooperation at various levels.Item Escherichia coli contamination of babies’ food-serving utensils in a district of West Sumatra, Indonesia(WHO Regional Office for South-East Asia, 2012-02) Kusuma, Aria; Eryando, Tris; Susanna, DewiBackground: Contamination of baby’s complementary food may occur with Escherichia coli from several sources including unclean utensils. We examined the relationship between socio-economic conditions, environmental factors, characteristics of food handlers and contamination of babies food-serving utensils with E. coli. Methods: The study was conducted in 21 villages of the Community Health Centre (CHC) Selayo in Indonesia. A cross-sectional design was used. A sample of 142 households, which had a 6-12 month-old baby on complementary food, was chosen randomly using midwives’ registration books. Respondents were interviewed using a semi-structured questionnaire. Check-lists were used for observations. Standard laboratory methods were used for collection of specimen and confirmation of contamination with E. coli. Results: More than half of the respondents (59.2%) used water that had high risk of contamination and 61.3% of the latrines did not meet the criteria of a healthy latrine. Waste management practices of nearly all respondents (97.9%) were below the standards set by the Ministry of Health. More than half of the respondents (68.3%) did not wash their hands with soap for 20 seconds and 52.1% did not use flowing water for washing hands. Majority of the respondents’ hands (57%, 81/142) and 72.2% (104/142) of the eating utensils were found to be contaminated by E. coli. Contaminated hands of food handlers were more likely to contaminate the babies food-serving utensils (OR: 3.7;95%CI: 1.62-8.46, p 0.002). Conclusion: Contamination of the hands of food handler was associated with contamination of babies food-serving utensils by E. coli. Hence, food handlers should be trained on proper hand washing methods.Item Decentralization of health services in India: barriers and facilitating factors(WHO Regional Office for South-East Asia, 2012-02) Kaur, Manmeet; Prinja, Shankar; Singh, Pravin K; Kumar, RajeshBackground: In India, the process of decentralization of health services started taking shape in the mid-1990s. Systemic reforms envisaged delegation of administrative and financial responsibilities at district level for management of health-care institutions in 23 states of India in 1999. Subsequently, some of these reforms became part of the National Rural Health Mission (NRHM) launched in 2005. This study aims to document the process of decentralization in health services with special reference to the barriers and facilitating factors encountered during formulation and implementation of reform policies. Methods: Secondary data were reviewed, health facilities were observed, and semi-structured interviews of the key actors involved in decentralization were carried out in Haryana (India). Results: Political and bureaucratic commitment to reforms was found to be the most important facilitating factor. Orientation training on decentralized administrative structures and performancebased resource distribution were the other important facilitators. Structural changes in administrative procedures led to improvement in the financial management system. Significant improvement in the public health infrastructure was observed. From 2004 to 2008, the state government increased the budget of health sector by nearly 60%. Frequent changes in the top administration at the state level hampered the decentralization process. Districts having a dynamic administrative leadership implemented decentralization more effectively than the rest. Conclusions: Decentralization of financial resources has improved the functioning of health services to some extent. Major policy decisions on decentralization of human resource management, increase in financial allocation, and greater involvement of community in decisionmaking are required.Item Why is every country not primed to use oral rehydration therapy to treat cases of diarrhoea?(WHO Regional Office for South-East Asia, 2012-02) Cash, Richard AItem Effect of patient education and standard treatment guidelines on asthma control: an intervention trial(WHO Regional Office for South-East Asia, 2012-02) Kotwani, Anita; Chhabra, Sunil KBackground: Denial of having a chronic condition, poor knowledge of the disease process and lack of adherence to standard treatment are often considered to be important factors that increase morbidity in asthma. We evaluated the effect of standard treatment guidelines and asthma education programme on asthma control among patients enrolled from a referral health facility of Delhi in India. Methods: Fifty patients who visited the health facility first time for treatment of asthma were enrolled after confirming the diagnosis of asthma by symptoms and reversible spirometry. Patients were interviewed at baseline using three researcher-administered questionnaires - quality of asthma management questionnaire, asthma control questionnaire (ACQ) and asthma knowledge questionnaire (AKQ). All patients were given pharmacotherapy according to standard treatment guidelines. In addition, every alternate patient was also given a face-to-face educational intervention. Patients were followed up at 2, 4, 8 and 12 weeks. The ACQ was used at each visit, and AKQ was reassessed at the twelfth week. The paired t test was used to detect significant changes in various domains of asthma control. Results: The knowledge of asthma among patients and the care provided by previous health-care providers were found to be poor at baseline assessment. The application of standard treatment guidelines improved asthma control by the second week and the changes became significant by the fourth week, which persisted till the twelfth week (p <0.0001). Educational intervention led to improvements in knowledge in several domains. Improvements in asthma symptoms began earlier among those who had additional educational intervention. Conclusions: Standard treatment guidelines and asthma education improved asthma control.Item Prevalence and predictors of self-medication in a selected urban and rural district of Sri Lanka(WHO Regional Office for South-East Asia, 2012-02) Wijesinghe, Pushpa R; Jayakody, Ravindra L; Seneviratne, Rohini de ABackground: Self-medication is widely practised in many developing countries. The determinants of self-medication need to be understood to design adequate medicine information policies and patient-dispenser education strategies. Hence, the prevalence of medicine use and predictors of self-medication were determined in Sri Lanka. Methods: In a community-based cross- sectional study, data were collected from 1800 adults selected from Gampaha and Polonnaruwa districts respectively. Study participants were sampled using a multistage cluster sampling technique. Trained public health midwives administered the questionnaire. Two Likert scales provided information on access to medical care and satisfaction with available pharmacy services. About 95% of the sampled population participated in the study. Results: Overall, prevalence of medication use (allopathic, traditional, home remedies) in urban and rural population was 33.9% and 35.3%, respectively. Self-medication prevalence of allopathic drugs in the urban sector (12.2%) was significantly higher than in the rural (7.9%) sector(p<0.05). In the urban sector, small household size and preference to have medicines from outside the pharmacies predisposed to self-medication. The higher acceptability of medical services and regularity of medical care decreased the likelihood of self-medication. In the rural sector, lower satisfaction about the healthcare providers’ concern for clients, lower satisfaction about affordability of medical care and higher satisfaction with technical competence of the pharmacy staff increased the likelihood of self-medication. In both urban and rural sectors, when symptom count increased, tendency to self-medicate decreased. Conclusions: Self-medication prevalence was higher in urban compared to rural areas in Sri Lanka. Some aspects of access to medical care, satisfaction with pharmacy services and perceived severity of the disease were found to be important determinants of self-medication.Item Risk factors of childhood tuberculosis: a case control study from rural Bangladesh(WHO Regional Office for South-East Asia, 2012-02) Karima, Mohamed R; Rahman, Mohamed A; Mamun, Shaikh AA; Alama, Mohamed A; Akhter, ShahnazBackground: Childhood tuberculosis (TB) is one of the major causes of childhood morbidity and mortality; however, it is relatively a neglected disease. Hence, we explored the risk factors for childhood TB. Methods: Ninty-five cases and 94 controls were selected during January to May 2011 from DOTS centres located in four sub-districts of Bangladesh. The exposure status of recently diagnosed childhood TB patients (<18-year-olds), who were sputum-positive, were compared with children who were sent to the laboratory with suspected tuberculosis but were found to be sputum-negative. Data were collected by a structured questionnaire. Crude odds ratios (OR), adjusted odds ratio (AOR) and 95% confidence intervals (CI) were estimated. Stepwise logistic regression model was used to identify independent predictors. Results: Children under 14 years of age (AOR: 0.25; 95% CI: 0.10-0.66), having completed primary education (AOR: 0.28; 95% CI: 0.10-0.74), whose fathers’ were in business or service(AOR: 0.24; 95% CI: 0.08-0.72), and who slept in a less crowded room (AOR: 0.32; 95% CI:0.14-0.76), lived in a house with a separate kitchen (AOR: 0.39; 95% CI: 0.16-0.96) had less chance of having TB. Those who had contact with cases of TB among relatives or neighbours were less likely to have TB (AOR: 0.28; 95% CI: 0.16-0.70) compared to those who had contact with a TB case in the family. Conclusion: Age, education, father’s occupation, crowding, kitchen location and intimate contact with a TB case were significantly associated with smear-positive childhood TB.Item Hospital or home? Scripting a high point in the history of TB care and control.(WHO Regional Office for South-East Asia, 2012-04) Uplekar, Mukund; Raviglionea, MarioItem Nipah virus outbreaks in Bangladesh: a deadly infectious disease.(WHO Regional Office for South-East Asia, 2012-04) Rahman, Mahmudur; Chakraborty, ApurbaDuring 2001-2011, multidisciplinary teams from the Institute of Epidemiology, Disease Control and Research (IEDCR) and International Centre for Diarrhoeal Disease Research, Bangladesh(icddr,b) identified sporadic cases and 11 outbreaks of Nipah encephalitis. Three outbreaks were detected through sentinel surveillance; others were identified through event-based surveillance. A total of 196 cases of Nipah encephalitis, in outbreaks, clusters and as isolated cases were detected from 20 districts of Bangladesh; out of them 150 (77%) cases died. Drinking raw date palm sap and contact with a case were identified as the major risk factors for acquiring the disease. Combination of surveillance systems and multidisciplinary outbreak investigations can be an effective strategy not only for detection of emerging infectious diseases but also for identification of novel characteristics and risk factors for these diseases in resource- poor settings.Item Role of modern technology in public health: opportunities and challenges.(WHO Regional Office for South-East Asia, 2012-04) Narain, Jai P; Ofrin, RodericoItem Prognostic indicators in patients with snakebite: Analysis of two-year data from a township hospital in central Myanmar.(WHO Regional Office for South-East Asia, 2012-04) Myo-Khin; Theingi-Nyunt; Nyan-Tun-Oo; Ye-HlaBackground: Rural people seek medical treatment for snakebite at peripheral health care facilities. Hence, identification of the characteristics, which can be used at peripheral levels of health care as reliable predictors of mortality, are required. Methods: Hospital records of 101 patients (70 males and 31 females) with age ranging from 3 to 80 years, admitted to Nahtogyi township hospital in central Myanmar during January 2005 to December 2006 were reviewed retrospectively. Binary logistic regression was used for estimating odds ratio (OR) and 95% Confidence Interval (CI) for various prognostic indicators of mortality. Results: Almost all snakebites were on extremities; more in legs (62%) than hands (37%). Most (52.5%) bites occurred in the morning (4 am to noon). Mean (SD) time for bite-to-hospital and bite-to-injection of anti-snake venom (ASV) was 134.6 (78.6) and 167 (187.8) minutes respectively. Eleven cases (10.9%) had died. Case fatality ratio (CFR) was significantly higher in 39 patients with un-clotted blood as compared to 62 patients with clotted blood (25.6% vs 1.6%, p <0.0005). Significantly higher CFR was observed in 49 patients who received ASV in >2 hours after the bite compared to 52 cases who received ASV within two hours (9.9% vs 0.9%, p <0.0001). Odds ratio of fatality were higher among those who had urine output of <400 ml in the first 24 hours (OR 26.4; 95% CI 2.4 to 288.3), un-clotted blood (OR 4.6; 95% CI 0.3 to 66.7), bite-to-injection time of >2 hours (OR 4; 95% CI 0.1 to 219.8) bite-to-hospital time of >2 hours (OR 3.1; 95%CI 0.1 to 136.3) and bites in the morning (OR 2; 95% CI 0.3 to 16.0). Conclusions: Clinical parameters could be used by healthcare providers to identify snakebite patients for referral, who may have fatal outcome.Item Performance of cause-specific childhood mortality surveillance by health workers using a short verbal autopsy tool.(WHO Regional Office for South-East Asia, 2012-04) Kumar, Rakesh; Kapoor, Suresh K; Krishnan, AnandBackground: The routine use of verbal autopsy in health-care delivery settings has been limited. Hence, the performance of neonatal and postneonatal verbal autopsy (VA) tools developed at the Comprehensive Rural Health Services Project (CRHSP), Ballabgarh (India), were assessed. Methods: Short VA tools developed by CRHSP were filled by health workers during their routine house visits while standard VA tools of the International Network of Field Sites with continuous Demographic Evaluation (INDEPTH) were filled by trained research workers for all 143 under-fivechildren deaths that occurred in 2008. The level of agreement in the cause of death assigned by the two VA tools was assessed by kappa and by comparison of the cause-specific mortality fractions. Results: Among 65 neonatal deaths, the cause specific mortality fraction (CSMF) was 43.1% and 40% for low birthweight, 15.4% and 26.2% for birth asphyxia, and 7.7% and 10.8% for pneumonia by INDEPTH and CRHSP VA tools respectively. In 78 deaths among 29-days to <5-year olds, the CSMF was 29.4% and 26.9% for diarrhoea, and 16.6% each for pneumonia using the INDEPTH and CRHSP VA tools respectively. Kappa for most causes of death was more than 0.8, except for birth asphyxia, which had a kappa of 0.678. Conclusions: Short VA tools have a satisfactory performance in field settings, which can be used routinely by health workers for filling the gaps in the cause-of-death information in places where medical certification of cause of death is deficient.
