Reporting system on mortality statistics in Lao People's Democratic Republic

The system to collect information on mortality statistics in Lao PDR is not well established, accurate and timely death information is therefore not available. This article reports the system and process to make the mortality statistical data of Lao PDR. The country has a paper-based resident registration system, using a death notification document, a death certificate, and a family census book. The death notification document is important as it provides the cause of death, which is issued from a health facility and the village office. In the event of a death occurring at home, the family representative needs to report to the village office verbally to obtain a death notification document. On the other hand, if the death occurred in a medical facility, a death notification document from a health facility is provided. The family representative should bring the death notification document to the district Home Affairs office to register the death and obtain a death certificate. After that, the family representative needs to bring the death certificate to the district Public Security office for an amendment in the family census book. ICD-10 is under development regarding death notification from health facilities under the Ministry of Health. However, it is unclear how death notification from village offices can adopt ICD-10 as the majority of deaths occur outside health facilities. A comprehensive and integrated mortality reporting system is necessary in order to create a holistic health policy and welfare for the country.

Assessment of cognitive function among adults aged ≥ 60 years using the Revised Hasegawa Dementia Scale: cross-sectional study, Lao People's Democratic Republic

BACKGROUND

Rapid population ageing remains an important concern for health, social and economics systems; thus, a broader assessment of cognitive decline among adults aged ≥ 60 years is essential. It is important to regularly collect reliable data through validated and affordable methods from people living in different areas and in different circumstances to better understand the significance of this health problem. This study aimed to identify the prevalence of cognitive impairment and the related risk factors by reassessing the scoring of the Revised Hasegawa Dementia Scale among older adults in the Lao People's Democratic Republic.

METHODS

A community-based cross-sectional investigation was conducted in rural and urban settings in six districts of three provinces in the country from January to July 2020. In total, 2206 individuals aged 60-98 years (1110 men and 1096 women) were interviewed in person using a pretested Lao version of the Revised Hasegawa Dementia Scale and the WHO STEPwise approach to noncommunicable disease (NCD) risk factor surveillance (the STEPS survey tool). The adjusted odds ratios (AORs) and 95% confidence intervals (95% CIs) were estimated using a logistic model.

RESULTS

The study found that 49.3% (1088/2206) of respondents (39.7% [441/1110] of men and 59.0% [647/1096] of women) had scores associated with some level of cognitive impairment. In addition to age, the following factors were significantly associated with cognitive impairment: having no formal education (AOR = 9.5; 95% CI: 5.4 to 16.8, relative to those with a university education), living in the northern region of the country (AOR = 1.4; 95% CI: 1.1 to 1.9, relative to living in the central region), living in a rural area (AOR = 1.5; 95% CI: 1.2 to 1.8), needing assistance with self-care (AOR = 1.8; 95% CI: 1.2 to 2.7) and being underweight (AOR = 1.5; 95% CI: 1.1 to 2.2). Factors associated with no cognitive impairment among older adults include engaging in moderate-intensity physical activity lasting for 10 minutes and up to 1 hour (AOR = 0.6; 95% CI: 0.5 to 0.8) and for > 1 hour (AOR = 0.6; 95% CI: 0.4 to 0.8).

CONCLUSIONS

Using the Lao version of the Revised Hasegawa Dementia Scale, this study found that more than half of adults aged ≥ 60 years had cognitive impairment, and this impairment was associated with several risk factors. The limitations of this study may include possible overdetection due to the cutoff point for the assessment of cognitive decline used in the Revised Hasegawa Dementia Scale, given that the participants were not familiar with the instrument. However, the study results can be used to help inform health policy in the Lao People's Democratic Republic regarding the urgent need for a routine data collection system and for providing an environment that addresses and reduces the identified risk factors for cognitive decline to mitigate their impact.

Factors affecting knowledge of National Health Insurance Policy among out-patients in Lao PDR: an exit interview study

BACKGROUND

Universal health coverage is target 3.8 of the Sustainable Development Goals. In many lower-middle-income countries, however, major coverage gaps exist. Those who do receive services often experience high out-of-pocket expenses. To achieve universal health coverage, Lao PDR, a lower-middle-income country in South-East Asia, is shifting from a fragmented model of health financing to a national health insurance scheme.

OBJECTIVE

The objective of this cross-sectional survey was to assess the knowledge of the NHI in Lao PDR among insured in- and out-patients using health services at selected public health facilities at provincial, district and health centre level in six provinces.

METHODS

This was a cross-sectional survey. Healthcare facilities were selected based on the rate of use of health services at the health facility and participants selected using systematic random sampling. Exit interviews were conducted with in- and out-patients of each selected health facility, using a pre-tested structured questionnaire. Descriptive statistics were generated including means (median), frequency and percentages. Poisson regression was applied to determine the factors associated with knowledge of the insurance scheme.

RESULTS

In total 326 participants were recruited (response rate 93%). Of these, less than two-thirds (62.3%) said they had their eligibility documents with them. Only 23.6% knew the co-payment fee at the health centre level; while 18.1% and 18.7% knew about the co-payment fee at the district and provincial healthcare level, respectively. A key determinant of accessing NHI and health services was knowledge of the scheme and its benefits.

CONCLUSION

This study suggests in Lao PDR, awareness about health insurance is low. More innovative demand-side strategies are needed to create awareness and understanding of the NHI and its benefits. Without an understanding of what insurance policies mean, universal health coverage cannot be achieved, even where appropriate and acceptable services are accessible.

Trends and risk factors for infant mortality in the Lao People's Democratic Republic

A high infant mortality rate (IMR) indicates a failure to meet people's healthcare needs. The IMR in Lao People's Democratic Republic has been decreasing but still remains high. This study aimed to identify the factors involved in the high IMR by analyzing data from 53,727 live births and 2189 women from the 2017 Lao Social Indicator Survey. The estimated IMR decreased from 191 per 1000 live births in 1978-1987 to 39 in 2017. The difference between the IMR and the neonatal mortality rate had declined since 1978 but did not change after 2009. Factors associated with the high IMR in all three models (forced-entry, forward-selection, and backward-selection) of multivariate logistic regression analyses were auxiliary nurses as birth attendants compared to doctors, male infants, and small birth size compared to average in all 2189 women; and 1-3 antenatal care visits compared to four visits, auxiliary nurses as birth attendants compared to doctors, male infants, postnatal baby checks, and being pregnant at the interview in 1950 women whose infants' birth size was average or large. Maternal and child healthcare and family planning should be strengthened including upgrading auxiliary nurses to mid-level nurses and improving antenatal care quality.

Factors associated with patient payments exceeding National Health Insurance fees and out-of-pocket payments in Lao PDR

BACKGROUND

Attaining universal health coverage is a target in the Sustainable Development Goals. In Lao PDR, to achieve universal health coverage, the government is implementing a national insurance scheme, initially targeting the informal sector.

OBJECTIVE

The purpose was to assess: i) the percentage of NHI patients who paid above the scheduled amount, based on individual billing payment; and ii) the factors related to overpayment.

METHODS

Descriptive cross-sectional study based on a structured questionnaire administered at health facilities in face-to-face interviews with 1,850 patients in six provinces.

RESULTS

All 1,850 participants worked in the informal sector. Of these, 78.8% of respondents (77.9% of in-patients; 79.5% of out-patients) made co-payments or were exempted from. Factors associated with in-patients paying above the scheduled fee were living in the province and district (OR = 2.8; 95%CI 1.2 to 6.3); not having documents with them (OR = 21.2; 95%CI 5.6 to 80.3); or not having documents (OR: 7.8; 95% CI 2.1 to 28.6). Significant factors associated with additional costs for out-patients were level of facility used at the provincial hospital (OR:1.4; 95% CI 1.1 to 1.9); older age (OR = 2.2; 95%CI 1.5 to 3.1); living in the province and district (OR = 2.3; 95%CI 1.5 to 3.7); living more than 5 km from the facility (OR = 1.4; 95%CI 1.1 to 1.9); buying medicine or supplies outside of the health facility (OR: 5.6; 95% CI 3.1 to 10.2); not bringing documents (OR:9.1; 95% CI 6.1 to 13.5), not having the right documents (OR: 8.9; 95% CI 5.4 to 14.8).

CONCLUSIONS

A number of patients paid above scheduled fee rates, which may deter people from utilising services when needing them. There is a need for increased understanding of the benefits of the national insurance scheme among patients and healthcare staff.

Disease frequency among inpatients at a tertiary general hospital in Lao PDR

In Lao People’s Democratic Republic (Lao PDR), reports on disease frequency are very limited. This study aimed to report frequencies of the main cause of admission among inpatients of a tertiary general hospital (Mittaphab Hospital) in Vientiane. Subjects were inpatients who were admitted from January 3 to February 2 in 2017. The dataset were made as a pilot run to establish hospital statistics. The data on sex, age, address (province), dates of admission and discharge, and main diagnosis were collected from paper-based medical charts. International Classification of Diseases 10 was applied for classifying the main diagnosis. During the 1-month period, 1,201 inpatients (637 males and 564 females) were admitted, including 171 (14.2%) aged <20 years and 254 (21.1%) aged ≥60 years. About 20% patients were from outside of Vientiane. Among them, 67.5% (62.5% in males and 73.8% in females) were admitted within 7 days. The main causes with more than 10% in males were injury and poisoning S00-T98 (49.8%), while those in females were injury and poisoning S00-T98 (25.2%), pregnancy and childbirth O00-O99 (19.0%), and diseases of genitourinary system N00-N99 (13.7%). Injury and poisoning S00-T98 among inpatients aged <20 years was 81.8% in males and 59.0% in females. Among those aged 20–59 years, it was 49.9% and 22.4%, and among those aged ≥60 years it was 22.3% and 16.9%, respectively. This is the first report on the frequencies of main diseases among inpatients in Lao PDR. Injury was the first main cause of admission at the tertiary hospital.

Antibiotic prescription for under-fives with common cold or upper respiratory tract infection in Savannakhet Province, Lao PDR

Background

The irrational use of antibiotics has been identified as a major problem in healthcare, and it can lead to antimicrobial resistance, treatment failure, and increased healthcare costs. Although many studies worldwide have focused on the irrational use of drugs, reports on prescription practice in Lao PDR remained limited. This study aimed to examine the patterns of antibiotic prescription for under-fives with common cold or upper respiratory tract infection (URTI) at pediatric outpatient divisions.

Methods

One provincial hospital (PH) at Kaisone Phomvihane and four district hospitals (DHs) at Songkhone, Champhone, Atsaphangthong, and Xepon in Savannakhet Province were selected. Healthcare providers at these hospitals were interviewed and medical records of under-fives from 2016 were examined.

Results

Of the 54 healthcare providers interviewed, 85.2% had seen the standard treatment guideline, 77.8% adhered to this guideline, and 90.7% knew about antimicrobial resistance, while 18.5% participated in antimicrobial resistance activities. Medical records of 576 outpatients (311 boys and 265 girls) with common cold or URTI were examined, 154 at the PH and 422 at the DHs. Although antibiotics prescription proportions were similar between facilities at both levels (68.8% and 70.9% at the PH and DHs, respectively), antibiotics were exclusively prescribed for URTIs (96.4%), not for common cold (4.9%). First-line antibiotics recommended by WHO Model List of Essential Medicines for Children the 6th List were prescribed for 81.5% of patients; mainly, beta-lactam antibiotics were prescribed (87.2% of prescribed antibiotics). There were no cases in which two or more antibiotics were prescribed. The correct dose according to the National STG was 31.9% as a whole. The difference in the correct dose between the PH (52.8%) and the DHs (24.4%) was significant (p < 0.001).

Conclusions

This study demonstrated the patterns of antibiotic prescription for under-fives with common cold or URTI among healthcare providers from two different levels of facilities. Although an appropriate number of generic first-line antibiotics in the essential drug list were prescribed, the dosage and duration of antibiotic use were not appropriate. In order to further improve antibiotic prescription practices, regulation by the government is necessary; this could also decrease antimicrobial resistance and improve treatment outcomes.

Underlying Cause of Death Recorded during 2013 to 2015 at a Tertiary General Hospital in Vientiane Capital, Lao PDR

In Lao People’s Democratic Republic (Lao PDR), the cause of death is not registered in death reports. As a result, the government cannot produce official reports that show mortality according to cause of death. This study aimed to report the underlying cause of death in a tertiary general hospital (Mittaphab Hospital) in Vientiane capital. Mittaphab hospital is a governmental teaching hospital with 300 beds for inpatient services specialized in orthopedics, neurology, and hemodialysis. Since a children hospital exists beside Mittaphab Hospital, severe pediatric cases are referred to the child hospital. HIV-positive cases and sputum positive tuberculosis are also transferred to the other specialized hospitals. All of the subjects in this study were patients who died in 2013–2015 at Mittaphab Hospital. Paper-based medical charts were examined by a medical doctor and staff from the medical records division. This chart review revealed that 1,509 patients (1,006 males and 503 females) died in this hospital during the study period. Of those, the number of patients aged <20 years and >80 years was small (6.2% and 7.7%, respectively). The most common underlying causes were injury (29.7%), cerebrovascular diseases (26.8%), renal disease (13.3%), infectious diseases (12.4%), and malignant neoplasm including brain tumor (4.8%). Among those aged 20–59 years, these percentages were 37.9%, 23.7%, 12.3%, 10.2%, and 5.0%, respectively. Although the patients visiting the hospital did not represent the whole population, the distribution of cause of death in the hospital was the only available information reported in Lao PDR.

Lao language version of the Revised Hasegawa's Dementia Scale

With the aging of society, the number of elderly with reduced cognitive function has been increasing worldwide. As a test to measure the cognitive function, the Revised Hasegawa’s Dementia Scale (HDS-R) has been used in Japan, Korea, and China. Since there was no HDS-R version for Laotians, the questionnaire and manual were developed through the cooperation of Lao and Japanese researchers. Back-translation was conducted to confirm the accuracy of the translation. The score on the 9-item HDS-R ranges 0 to 30 points, and reduced cognitive function is usually defined as a score of 20 points or lower. After receiving explanation regarding the use of the tool and practicing its implementation, 3 female doctors interviewed 30 superficially healthy volunteers aged 31 to 84 years (12 males and 18 females) who lived with his/her family in Vientiane Capital, Lao PDR. Their score distributed from 4 to 30 points, with an average of 24.7 (standard deviation 5.4) points. Six (20.0%) participants scored 20 points or lower. The discussion before and after the pilot interviews revealed that the following changes needed to be made in accordance to the culture of Lao people; 1) order of date in Question 2, 2) words to be memorized in Questions 4 and 7, 3) objects to be memorized using pictures, not actual objects, in Question 8. Additionally, we introduced new two rules; a clear time definition for no reply (10 seconds), and repetition of questions twice for those with ear problems. The revised version of the HDS-R was thought to be an appropriate standard questionnaire for use in studies on cognitive function among Laotians.

Factors associated with routine immunization coverage of children under one year old in Lao People's Democratic Republic

BACKGROUND

Routine vaccination is administered free of charge to all children under one year old in Lao People's Democratic Republic (Lao PDR) and the national goal is to achieve at least 95% coverage with all vaccines included in the national immunization program by 2025. In this study, factors related to the immunization system and characteristics of provinces and districts in Lao PDR were examined to evaluate the association with routine immunization coverage.

METHODS

Coverage rates for Bacillus Calmette-Guerin (BCG), Diphtheria-Tetanus-Pertussis-Hepatitis B (DTP-HepB), DTP-HepB-Hib (Haemophilus influenzae type B), polio (OPV), and measles (MCV1) vaccines from 2002 to 2014 collected through regular reporting system, were used to identify the immunization coverage trends in Lao PDR. Correlation analysis was performed using immunization coverage, characteristics of provinces or districts (population, population density, and proportion of poor villages and high-risk villages), and factors related to immunization service (including the proportions of the following: villages served by health facility levels, vaccine session types, and presence of well-functioning cold chain equipment). To determine factors associated with low coverage, provinces were categorized based on 80% of DTP-HepB-Hib3 coverage (<80% = low group; ≥80% = high group).

RESULTS

Coverages of BCG, DTP-HepB3, OPV3 and MCV1 increased gradually from 2007 to 2014 (82.2-88.3% in 2014). However, BCG coverage showed the least improvement from 2002 to 2014. The coverage of each vaccine correlated with the coverage of the other vaccines and DTP-HepB-Hib dropout rate in provinces as well as districts. The provinces with low immunization coverage were correlated with higher proportions of poor villages.

CONCLUSIONS

Routine immunization coverage has been improving in the last 13 years, but the national goal is not yet reached in Lao PDR. The results of this study suggest that BCG coverage and poor villages should be targeted to improve nationwide coverage.

Health policy evolution in Lao People's Democratic Republic: context, processes and agency

During the last 20 years Lao People's Democratic Republic has successfully developed and adopted some 30 health policies, strategies, decrees and laws in the field of health. Still, the implementation process remains arduous. This article aims at discussing challenges of health policy development and effective implementation by contextualizing the policy evolution over time and by focusing particularly on the National Drug Policy and the Health Care Law. Special attention is given to the role of research in policymaking. The analysis was guided by the conceptual framework of policy context, process, content and actors, combined with an institutional perspective, and showed that effective implementation of a health policy is highly dependent on both structures and agency of those involved in the policy process. The National Drug Policy was formulated and adopted in a short period of time in a resource-scarce setting, but with dedicated policy entrepreneurs and support of concerned international collaborators. Timely introduction of operational health systems research played a crucial role to support the implementation, as well as the subsequent revision of the policy. The development of the Health Care Law took several years and once adopted, the implementation was delayed by institutional legacies and issues concerning the choice of institutional design and financing, despite strong support of the law among the policymakers. Among many factors, timing of the implementation appeared to be of crucial importance, in combination with strong leadership. These two examples show that more research, that problematizes the complex policy environment in combination with improved communication between researchers and policymakers, is necessary to inform about measures for effective implementation. A way forward can be to strengthen the domestic research capacity and the international research collaboration regionally as well as globally.

Building the national drug policy on evidence--a cross sectional study on assessing implementation in Lao PDR

The National Drug Policy (NDP) of Lao PDR, endorsed in 1993, has since 1995 been implemented through an intervention program in five pilot areas out of 18 provinces, including training of health personnel. The aim was to assess the impact of the NDP program to get evidence for revising the policy. In a cross sectional design, comparisons were made between the pilot province of Luangphrabang (LPB) and the non-pilot province of Sayabury (SBR). In each province, three districts were purposively chosen. Four pharmacies at the public hospitals were included, while 20 private pharmacies were randomly selected. A set of 29 combined indicators was utilized. One hundred and ten prescriptions for under-five children with simple diarrhea and 240 adult outpatient prescriptions were sampled. Furthermore, twelve health care managers were interviewed on knowledge and attitudes. LPB health managers had better knowledge of NDP concepts. Significantly more essential drugs (ED) were available in the private pharmacies in the pilot province. The proportion of prescriptions of ED in hospitals was higher in the pilot province (95% in LPB vs 86% in SBR; p<0.001). Fewer drugs per patient were prescribed in the pilot province (2.7 vs 3.3, p<0.001), and the management of simple diarrhea in children was significantly more in accordance with Standard Treatment Guidelines. The pilot province performed significantly better regarding several aspects of quality and rational use of drugs, probably related to the implementation program. National as well as regional and global diffusion of research findings is recommended towards evidence-based national drug policies.
