Knowledge, attitudes, and practices on climate change and dengue in Lao People's Democratic Republic and Thailand.

BACKGROUND: Dengue is linked with climate change in tropical and sub-tropical countries including the Lao People's Democratic Republic (Laos) and Thailand. Knowledge about these issues and preventive measures can affect the incidence and outbreak risk of dengue. Therefore, the present study was conducted to determine the knowledge, attitudes, and practices (KAP) among urban and rural communities and government officials about climate change and dengue in Laos and Thailand. METHODS: A cross-sectional KAP survey about climate change and dengue were conducted in 360 households in Laos (180 urban and 180 rural), 359 households in Thailand (179 urban and 180 rural), and 20 government officials (10 in each country) using structured questionnaires. Data analysis was undertaken using descriptive methods, principal component analysis (PCA), Chi-square test or Fisher's exact test (as appropriate), and logistic regression. RESULTS: Significant differences among the selected communities in both countries were found in terms of household participant's age, level of education, socioeconomic status, attitude level of climate change and KAP level of dengue (P < 0.05; 95% CI). Overall, participants' KAP about climate change and dengue were low except the attitude level for dengue in both countries. The level of awareness among government officials regarding the climatic relationship with dengue was also low. In Lao households, participants' knowledge about climate change and dengue was significantly associated with the level of education and socioeconomic status (SES) (P < 0.01). Their attitudes towards climate change and dengue were associated with educational level and internet use (P < 0.05). Householders' climate change related practices were associated with SES (P < 0.01) and dengue related practices were associated with educational level, SES, previous dengue experience and internet use (P < 0.01). In Thailand, participants' knowledge about climate change was associated with the level of education and SES (P < 0.01). Their attitudes towards climate change were associated with residence status (urban/rural) and internet use (P < 0.05); climate change related practices were associated with educational level and SES (P < 0.05). Dengue related knowledge of participants was associated with SES and previous dengue experience (P < 0.05); participants' dengue related attitudes and practices were associated with educational level (P < 0.01). CONCLUSION: The findings call for urgently needed integrated awareness programs to increase KAP levels regarding climate change adaptation, mitigation and dengue prevention to improve the health and welfare of people in these two countries, and similar dengue-endemic countries.

Improvement of Quality of Antenatal Care (ANC) Service Provision at the Public Health Facilities in Lao PDR: Perspective and Experiences of Supply and Demand Sides.

BACKGROUND: The maternal mortality rate in Lao PDR (Laos) is still the highest in Southeast Asia, at 197 per 100,000 live births. Antenatal care (ANC) could contribute to maternal and child mortality reduction. The quality of ANC service remains inadequate and little information is available on the quality of health education and counseling services of health providers in Laos. This study aims to gain insight into the perceptions of stakeholders on both supply and demand sides of public ANC services in Laos and evidence for recommendations to improve the quality of ANC services. METHODS: Semi-structured interviews were conducted with 50 participants from different stakeholder groups; on the demand side, couples with a currently pregnant woman and mothers with children under one year of age and a family member; and on the supply side, health providers, managers, policy makers of the Ministry of Health, and development partners. The interviews were voice recorded and transcribed verbatim for analysis by open and thematic coding, using the MAXQDA software program. RESULTS: All respondents reported that the number of pregnant women who visit ANC services has increased. However, an analysis of the supply side identified issues related to the quality of ANC that need to be improved in the areas of facilities, human resources, privacy and confidentiality, providers' behavior, attitudes, and ineffective communication skills when it comes to providing health education and counseling to pregnant women and their family members. The analysis of the demand side mainly emphasized the issues of providers' behavior, attitude, communication and unequal treatment, and the lack of privacy. Both sides also suggested solutions to the problems, such as training, effective materials, rewarding good role models, and building a feedback system. CONCLUSION: The number of public ANC services has increased, but both supply and demand sides experienced challenges with the quality of ANC. All respondents proposed possible solutions to improve quality of ANC service in public health facilities in Laos.

Do health care providers give sufficient information and good counseling during ante-natal care in Lao PDR?: an observational study.

BACKGROUND: It is increasingly recognized that improving the quality of maternal health care delivery is of utmost importance in many countries. In Laos, the quality of antenatal care (ANC) service remains inadequate, but it has never been assessed thoroughly. This study aims to determine the ANC quality at the urban and rural public health facilities in Laos and provides suggestions to improve health education and counseling in addition to other routine care in public ANC services. METHODS: This health-facility based, cross-sectional observation study included both health providers (n = 77) and pregnant women (n = 421) from purposively selected health facilities (n = 16). Information on the mothers' current pregnancies, previous visits and their last children was collected. The time spent for each ANC session as well as ANC services provided were recorded. Descriptive and inferential statistics were applied to analyze the data. RESULTS: Overall performance of ANC services by health care providers was poor in both urban and rural areas. Insufficient provision of information on danger signs during pregnancy, nutrition, breast feeding and iron supplements was revealed. Generally the communication skills, behavior and attitude of health providers were very poor. Less than a quarter of pregnant women were treated with kindness and respect. Only 4% of the observed ANC session took privacy into consideration. Less than 10% of available information materials were used during each ANC session. None of the health providers in both rural and urban areas performed specific counseling. Overall mean (SD) time-spent for each ANC session was 16.21 (4.28) minutes. A positive correlation was identified between the length of working experience of health providers and their physical performance scores (adjusted R square = 0.017). CONCLUSIONS: The overall performance of ANC services by health care providers was inadequate in both urban and rural areas. Insufficient provision of health education and poor communication skills of health care providers were revealed. Existing IEC materials were scarcely used. Taking action to improve the quality of ANC services by training and providing specific guidelines, creating dedicated rooms, and providing sufficient and effective materials for counseling are all greatly needed in public health facilities in Laos.

Trust in healthcare: methodological and conceptual insights from mixed-method research in Lao People's Democratic Republic.

BACKGROUND: Global health foregrounds trust as a key requirement for the achievement of international health initiatives, but it remains an elusive concept that is often mobilised without consideration of its dimensions, drivers and downstream behavioural consequences. This paper aims to contribute to the conceptual development and measurement of 'patient trust in primary healthcare' from the lower middle-income country perspective of rural Lao PDR. METHODS: A two-phase mixed-method research design was implemented between January 2021 and April 2023. Phase 1 involved exploratory qualitative research to understand the local expressions and dimensions of patient trust in primary healthcare, with 25 semistructured interviews and 17 focus group discussions (120 participants) in eight villages in Bokeo Province. Phase 2 involved explanatory research to assess patterns of trust systematically at scale in 14 villages across four provinces, wherein 26 cognitive interviews, 17 expert interviews and non-participant community observations informed a community census survey with 1838 participants. We analysed qualitative data through content-oriented thematic analysis and developed an 8-item trust scale on that basis. Quantitative data analysis used descriptive statistical and regression analysis. RESULTS: We found that trust in primary healthcare is readily understood and intrinsically valuable in rural Lao PDR. Key dimensions included communication, respectful care, relationship, fairness, integrity, reputation, assurance of treatment and competence. The survey highlighted that reputation, competence, integrity and respectful care had the lowest trust scores. Health centre operations predicted the local expressions of trust. The behavioural consequences of trust were limited to a positive statistical association with antenatal care uptake among pregnant women but outweighed by alternative measures that also captured the availability of healthcare facilities. CONCLUSIONS: Overall, the development of our quantitative trust scale offers a process model for future researchers. We conclude that interpersonal, institutional and service-related trust require more explicit recognition in health system development and integration into health policy.

Community engagement for stakeholder and community trust in healthcare: Short-term evaluation findings from a nationwide initiative in Lao PDR.

BACKGROUND: Trust remains a critical concept in healthcare provision, but little is known about the ability of health policy and interventions to stimulate more trusting relationships between communities and the health system. The CONNECT (Community Network Engagement for Essential Healthcare and COVID-19 Responses Through Trust) Initiative in Lao PDR provided an opportunity to assess the community-level impact of a trust-building community engagement approach. METHODS: A mixed-method process evaluation was implemented from 10/2022-12/2023 among 14 diverse case study communities in four provinces across Lao PDR. Data collection involved two rounds of census surveys (3161 observations incl. panel data from 618 individuals) including an 8-item trust scale, 50 semi-structured interviews with villagers, and 50 contextualizing key informant interviews. The two data collection rounds were implemented before and three months after village-based CONNECT activities and helped discern impacts among activity participants, indirectly exposed villagers, and unexposed villagers in a difference-in-difference analysis. RESULTS: Stakeholders attested strong support for the CONNECT Initiative although community-level retention of trust-related themes from the activities was limited. Quantitative data nevertheless showed that, at endline, the 8-item trust index (from [-8 to +8]) increased by 0.95 points from 4.44 to 5.39 and all trust indicators were universally higher. Difference-in-difference analysis showed that villagers exposed to the CONNECT activities had a 1.02-index-point higher trust index compared to unexposed villagers. Trust impacts improved gradually over time and were relatively more pronounced among men and ethnic minority groups. CONCLUSIONS: The CONNECT Initiative had considerable direct and systemic effects on community members' trust in their local health centers in the short term, which arose from strong stakeholder mobilization and gradual institutional learning. Relational community engagement approaches have the potential to create important synergies in health policy and broader cross-sectorial strategies, but also require contextual grounding to identify locally relevant dimensions of trust.

Provider perspectives on constraints in providing maternal, neonatal and child health services in the Lao People's democratic republic: a qualitative study.

BACKGROUND: To reduce its high maternal and neonatal mortality rate and meet Millennium Development Goals four and five, Lao PDR has adopted a national 'Strategy and Planning Framework of Implementation of Maternal, Neonatal and Child Health Services'. This paper reports on implementation constraints identified in three demonstration sites. METHODS: The objectives of this paper are to analyse health worker perceptions of the implementation of the strategy and constraints faced during implementation. A qualitative design was used with interviews conducted at health facilities in three demonstration provinces. Data were collected through key interviews with provincial/district hospital providers (n = 27), health centre staff (n = 8) and village health volunteers (n = 10). Data was analysed informed by Hanson et al's health system constraint framework. RESULTS: In each of the demonstration sites, the Maternal, Neonatal and Child Health program was generally well-understood and the different activities were being implemented. Perceived implementation constraints related mainly to a mix of supply and demand factors. Supply-side constraints related to inadequate human resources, poor remuneration, weak technical guidance, minimal supervision and limited equipment. Demand-side constraints related mainly to cost, limited access to transport, cultural practices and language. Other constraints related to broader strategic management and cross-sectoral contextual constraints. Contextual constraints included low levels of limited education, women's position in society and poor transport and communications networks. These factors influenced the implementation process and if not addressed, may reduce the effectiveness of the policy and scale-up. CONCLUSION: The Lao PDR has a well-defined Maternal, Neonatal and Child Health program. Analysis of the constraints experienced by service providers in implementing the program however, is essential for scaling-up the initiative. To achieve effective implementation and scale-up a number of concurrent interventions are needed to address identified constraints. More research is needed to identify the optimal combination of interventions to improve these constraints. The broader contextual characteristics require longer-term, cross-sectoral action.

Health policymakers' knowledge and opinions of physicians smoking and tobacco policy control in Lao PDR.

BACKGROUND: In 2007, a regulation on smoke-free health facilities and institutions was adopted by the Lao government. Little is known about health policymakers' knowledge and opinions regarding tobacco policy control, including physicians' behaviour. This paper aims to describe the knowledge of Lao health policymakers and their opinions regarding physicians tobacco use and national smoking policy control. METHODS: In 2007, we made a qualitative explorative study with data from a purposive sample of 18 key informants through semi-structured, face-to-face interviews. The key informants, who were heads of departments, directors of hospitals and directors of centres, mainly worked at the national level, and some provincial levels. Content analysis was used. RESULTS: Policymakers perceived the inadequate implementation of a smoke-free regulation and policy as being a barrier and that the general public may not accept physicians smoking, since they are regarded as role models. Most of the respondents mentioned that regulations or laws related to control of smoking in health institutions are available in Laos, but they lacked detailed knowledge of them probably because regulations as well as the smoke-free policy documents were not widely disseminated. The respondents agreed that anti-smoking education should be integrated in the training curricula, especially in the medical schools, and that the provision of counselling on health consequences from smoking and methods of smoking cessation was important. CONCLUSION: This study contributes to tobacco policy evidence and to knowledge regarding factors related to the uptake of evidence into policymaking. Dissemination and implementation of a tobacco control policy nationally, and integration of tobacco cessation training programs in the curricula were found to be productive approaches for improvement.

Defining and redefining harm reduction in the Lao context.

The response to drug use in Laos has focused on reducing opium supply (supply reduction) and rates of drug use (demand reduction). However, recently there is increased interest among government counterparts to discuss and develop broader responses to injecting drug use (IDU) including the introduction of harm reduction programs. The concept of harm reduction has just been introduced to Lao PDR and as yet there is no agreement on a definition of the concept. We highlight here a range of issues that remain controversial in Lao PDR in the HIV, drug use and harm reduction discourse, the definition of 'harm reduction' and related terms; and the scope of harm reduction.This was a qualitative study, consisting of in-depth interviews with 27 law enforcement and 8 health officers who work in the fields of HIV and/or drug control about their understanding of HIV related to drug use, and concepts of harm reduction. Content analysis was performed to identify the coding, categories and themes.We found that law enforcement officers in particular had limited understanding about harm reduction and the feasibility and appropriateness of harm reduction services in the Lao context.Harm reduction should be a core element of a public health response to HIV where drug use and IDU exists. Recommendations include the necessity of increasing the awareness of harm reduction among law enforcement officers and providing appropriate evidence to support the needs of harm reduction policy and programs. HIV prevention and treatment strategies should be integrated within existing social and cultural frameworks, working with the task force for HIV/IDU and other government counterparts.

Evaluation strategies for measuring pneumococcal conjugate vaccine impact in low-resource settings.

OBJECTIVES: Pneumococcal conjugate vaccines (PCVs) are effective in reducing pneumococcal disease. We measured 13-valent PCV (PCV13) effect on different pneumococcal outcomes using diverse studies in Lao People's Democratic Republic. METHODS: Studies included: pre-PCV13 population-based record review of hospitalized childhood pneumonia cases; acute respiratory infection (ARI) study post-PCV13 to demonstrate effectiveness (VE) against hypoxic pneumonia; invasive pneumococcal disease (IPD) surveillance in all ages (2004-2018); carriage studies in children hospitalized with ARI (2013-2019); community carriage surveys pre- and post-PCV13. RESULTS: Annual pneumonia incidence rate in children pre-PCV13 was 1,530 (95% confidence interval [CI] 1,477-1,584) per 100,000. Adjusted VE against hypoxic pneumonia was 37% (95% CI 6-57%). For IPD, 85% (11/13) of cases were due to vaccine-types pre-PCV13, and 43% (3/7) post-PCV13 in children aged <5 years; for ≥5 years, 61% (27/44) and 42% (17/40), respectively. For ARI cases, adjusted VE for vaccine-type carriage was 39% (95% CI 4-60) in <5 year olds; slightly higher than community surveys (23% [95% CI 4-39%] in 12-23 month olds). CONCLUSIONS: Despite limited baseline data, we found evidence of PCV13 impact on disease and carriage. Our approach could be used in similar settings to augment existing WHO PCV evaluation guidelines.

Smoking among Lao medical doctors: challenges and opportunities for tobacco control.

BACKGROUND: Smoking is an increasing threat to health in low-income and middle-income countries and doctors are recognised as important role models in anti-smoking campaigns. OBJECTIVES: The study aimed to identify the smoking prevalence of medical doctors in Laos, their tobacco-related knowledge and attitudes, and their involvement in and capacity for tobacco prevention and control efforts. METHODS: This was a cross-sectional national survey by a researcher-administered, face-to-face questionnaire implemented at provincial health facilities throughout the central (including national capital), northern and southern regions of Laos in 2007. Both descriptive and inferential statistics were used. RESULTS: Of the 855 participants surveyed, 9.2% were current smokers and 18.4% were ex-smokers; smoking was least common in the central region (p<0.05) and far more prevalent in males (17.3% vs 0.4%; p<0.001). Smoking was concentrated among older doctors (p <0.001). Over 84% of current smokers wanted to quit, and 74.7% had made a recent serious attempt to do so. Doctors had excellent knowledge and positive attitudes to tobacco control, although smokers were relatively less knowledgeable and positive on some items. While 78% of doctors were engaged in cessation support, just 24% had been trained to do so, and a mere 8.8% considered themselves 'well prepared'. CONCLUSION: The willingness of doctors to take up their tobacco control role and the lower smoking rates among younger respondents offers an important window of opportunity to consolidate their knowledge, attitudes, skills and enthusiasm as cessation advocates and supports.

Maternal health literacy on mother and child health care: A community cluster survey in two southern provinces in Laos.

RATIONAL: Increased maternal health literacy (MHL) has contributed considerably to maternal and child health outcomes in many countries. Malnutrition, and low coverage of child vaccination and breastfeeding are major health concerns in Laos, but there is little insight into mothers' literacy on these issues. The aim of this study was to identify the level of MHL of Lao mothers and to explore factors influencing it, in order to provide evidence that can inform policies and planning of health services. METHODS: A cross-sectional survey was conducted using a questionnaire on health literacy (ability to access, understand, appraise and apply health-related information) in relation to care during pregnancy, childbirth, and the postpartum period. We interviewed 384 mothers with children aged under five years; 197 from urban and 187 from rural areas. Descriptive and inferential statistics were applied to analyze the data. RESULTS: Overall, MHL of Lao mothers was very low in both urban and rural areas; 80% of mothers had either inadequate or problematic MHL, while only 17.4% had sufficient and 3.5% excellent MHL. The MHL scores were significantly higher in urban than in rural areas. One third of mothers found it very difficult to access, understand, appraise and apply information on mother and child (MCH). Health personnel were the main source of MCH information for the mothers. Years of schooling, own income, health status, and number of ANC visits significantly predicted a higher level of MHL (R square = 0.250; adjusted R square = 0.240, P = <0.001). CONCLUSIONS: MHL of Lao mothers was inadequate in both urban and rural areas. Socio-demographics and key practices of the mothers were significantly associated with a better level of MHL. Health education on MHL to mothers in both urban and rural areas needs attention, and could best be done by improving the quality of health providers' provision of information.

Dengue Seroprevalence and Seroconversion in Urban and Rural Populations in Northeastern Thailand and Southern Laos.

Dengue is the most rapidly spreading mosquito-borne viral disease in the world. The detection of clinical cases enables us to measure the incidence of dengue infection, whereas serological surveys give insights into the prevalence of infection. This study aimed to determine dengue seroprevalence and seroconversion rates in northeastern Thailand and southern Laos and to assess any association of mosquito control methods and socioeconomic factors with dengue virus (DENV) infection. Cross-sectional seroprevalence surveys were performed in May and November 2019 on the same individuals. Blood samples were collected from one adult and one child, when possible, in each of 720 randomly selected households from two urban and two rural sites in both northeastern Thailand and southern Laos. IgG antibodies against DENV were detected in serum using a commercial enzyme-linked immunosorbent assay (ELISA) kit. Overall, 1071 individuals participated in the study. The seroprevalence rate was high (91.5%) across all 8 study sites. Only age and province were associated with seroprevalence rates. There were 33 seroconversions during the period from May to November, of which seven reported fever. More than half of the seroconversions occurred in the rural areas and in Laos. Dengue seroconversion was significantly associated with young age (<15 years old), female gender, province, and duration of living in the current residence. No socioeconomic factors or mosquito control methods were found to be associated with seroprevalence or seroconversion. Notably, however, the province with most seroconversions had lower diurnal temperature ranges than elsewhere. In conclusion, our study has highlighted the homogeneity of dengue exposure across a wide range of settings and most notably those from rural and urban areas. Dengue can no longer be considered to be solely an urban disease nor necessarily one linked to poverty.

Student motorcyclists' mobile phone use while driving in Vientiane, Laos.

To investigate mobile phone use while driving among student motorcyclists in Laos, we conducted a school-based questionnaire survey in central Vientiane in May 2014. Of the 883 high school students who reported to drive motorcycles at least once a week, 40% have ever used phones while driving motorcycles in both sexes. Those phone users had longer driving exposures than non-users, with about half engaging in phone use while driving at least 2 days a week and 70% engaging for 1 min or longer on an average day. They reported not just talking on the phone while driving but operating the phone such as dialling and text-messaging. In some instances, phone use was reportedly involved in their past crash experiences. To formulate a sound policy on this emerging distracting behaviour among motorcyclists, its contribution to the occurrence of overall crashes among motorcyclists should be investigated.

Road traffic injury among child motorcyclists in Vientiane Capital, Laos: a cross-sectional study using a hospital-based injury surveillance database.

This study investigated the distribution of motorcyclists, including drivers and passengers, who were involved in road traffic crashes and admitted to hospital in Vientiane Capital, Laos. The focus was on child motorcycle drivers and passengers under 15 years. A hospital-based injury surveillance database in Vientiane Capital was used. The surveillance was performed in two hospitals. From 1 September to 31 December 2009, 3968 patients were admitted to the participating hospitals with road traffic injuries. Patients under 15 years accounted for 10.8% (427/3968). The majority of patients under 15 years were motorcycle drivers or passengers (71.7%, 306/427). Child motorcyclists including drivers and passengers were less likely to wear a helmet than adults (adjusted odds ratio [OR], 0.3, 95% confidence interval [CI], 0.2-0.5, for children 10-14 years; adjusted OR: 0.1, 95% CI, 0.05-0.4, for children under 10 years). It is suggested that stricter regulation enforcement for child motorcycle drivers and passengers may be needed. In addition, barriers against wearing helmets for motorcycle drivers and passengers in Laos should also be examined in further studies.

Roadside observation of secondary school students' commuting to school in Vientiane, Laos.

To investigate modes of secondary school students' commuting to school and their unsafe driving practices in Laos, we conducted a roadside observation in front of the gate of a selected school in central Vientiane in December 2011. Of the 544 students observed, the majority came to school on foot (43%), followed by motorcycle (36%), and bicycle (14%). Of the 195 students who commuted by motorcycle, 45 (23%) drove it themselves. Of the 150 students who commuted as pillion riders, 35 (23%) were driven by a student or another child driver. The prevalence of helmet use among students (3%) was much lower than adults (66%). It was common for adult drivers to wear a helmet but to leave student pillion riders unhelmeted on the same motorcycle. Carrying two or three pillion riders was also often observed. The study revealed the necessity for measures to promote safe travel to school.
