The impact of a complex school nutrition intervention on double burden of malnutrition among Thai primary school children: a 2-year quasi-experiment

OBJECTIVE

This study assessed the impacts of the Dekthai Kamsai programme on overweight/obesity, underweight and stunting among male and female primary school students.

STUDY DESIGN

A quasi-experiment was conducted in 16 intervention and 19 control schools across Thailand in 2018 and 2019. In total, 896 treated and 1779 control students from grades 1 to 3 were recruited. In intervention schools, a set of multifaceted intervention components were added into school routine practices. Anthropometric outcomes were measured at baseline and at the beginning and end of every school term.

METHODS

Propensity score matching with linear and Poisson difference-in-difference analyses were used to adjust for the non-randomisation and to analyse the intervention's effects over time.

RESULTS

Compared with controls, the increases in mean BMI-for-age Z-score (BAZ) and the incidence rate of overweight/obesity were lower in the intervention schools at the 3rd, 4th and 8th measurements and the 3rd measurement, respectively. The decrease in mean height-for-age Z-score (HAZ) was lower at the 4th measurement. The decrease in the incidence rate of wasting was lower at the 5th, 7th and 8th measurements. The favourable impacts on BAZ and HAZ were found in both sexes, while the favourable impact on overweight/obesity and unfavourable impact on wasting were found in girls.

CONCLUSIONS

This intervention might be effective in reducing BAZ, overweight/obesity, poor height gain, but not wasting. These findings highlight the benefits of a multifaceted school nutrition intervention and a need to incorporate tailor-made interventions for wasting to comprehensively address the double burden of malnutrition.

Cost-effectiveness analysis of endovascular coiling and neurosurgical clipping for aneurysmal subarachnoid hemorrhage in Thailand

BACKGROUND

For patients with aneurysmal subarachnoid hemorrhage (aSAH), the Universal Coverage Scheme in Thailand covers the full costs of surgical and endovascular procedures except for those of embolization coils and assisting devices. Costs and effectiveness were compared between endovascular coiling and neurosurgical clipping to inform reimbursement policy decisions.

METHODS

Costs and quality-adjusted life years (QALYs) were compared between coiling and clipping using the decision tree and Markov models. Mortality and functional outcomes of clipping were derived from national and hospital databases, and relative efficacies of coiling were obtained from meta-analyses of randomized controlled trials. Risks of rebleeding were abstracted from the International Subarachnoid Aneurysm Trial. Costs of the primary treatments, retreatments and follow-up care as well as utilities were obtained from hospital-based data. Non-health and indirect costs were abstracted from standard cost lists.

RESULTS

Coiling and clipping contributed 10.59 and 9.28 QALYs to patients aged in their 50s. Under the societal and healthcare perspectives, the incremental costs incurred by coiling compared with clipping were US$1923 and $4343, respectively, which were equal to the incremental cost-effectiveness ratio of US$1470 and $3321 per QALY gained, respectively. Coiling became a cost-saving option when the costs of coil devices were reduced by 65.7%. At the country's cost-effectiveness threshold of US$5156, the probability of coiling being cost-effective was 71.3% and 65.6%, under the societal and healthcare perspectives, respectively.

CONCLUSION

Endovascular treatment for aSAH is cost-effective and this evidence supports coverage by national insurance.

Effects of a national policy advocating rational drug use on decreases in outpatient antibiotic prescribing rates in Thailand

Objective:

This study examined the effects of a national policy advocating rational drug use (RDU), namely, the ‘RDU Service Plan’, starting in fiscal year 2017 and implemented by the Thai Ministry of Public Health (MOPH), on trends in antibiotic prescribing rates for outpatients. The policy was implemented subsequent to a voluntary campaign involving 136 hospitals, namely, the ‘RDU Hospital Project’, which was implemented during fiscal years 2014-2016.

Methods:

Hospital-level antibiotic prescribing rates in fiscal years 2014-2019 for respiratory infections, acute diarrhea, and fresh wounds were aggregated for two hospital groups using equally weighted averages: early adopters of RDU activities through the RDU Hospital Project and late adopters under the RDU Service Plan. Pre-/post-policy annual changes in the prescribing levels and trends were compared between the two groups using an interrupted time-series analysis.

Results:

In fiscal years 2014-2016, decreases in antibiotic prescribing rates for respiratory infections and acute diarrhea in both groups reflected a trend that existed before the RDU Service Plan was implemented. The immediate effect of the RDU Service Plan policy occurred in fiscal year 2017, when the prescribing level among the late adopters dropped abruptly for all three conditions with a greater magnitude than in the decrease among the early adopters, despite nonsignificant differences. The medium-term effect of the RDU Service Plan was identified through a further decreasing trend during fiscal years 2017-2019 for all conditions in both groups, except for acute diarrhea among the early adopters.

Conclusions:

The national policy on rational drug use effectively reduced antibiotic prescribing for common but questionable outpatient conditions.

Financial risk protection of Thailand's universal health coverage: results from series of national household surveys between 1996 and 2015

BACKGROUND

Thailand, an upper-middle income country, has demonstrated exemplary outcomes of Universal Health Coverage (UHC). The country achieved full population coverage and a high level of financial risk protection since 2002, through implementing three public health insurance schemes. UHC has two explicit goals of improved access to health services and financial protection where use of these services does not create financial hardship. Prior studies in Thailand do not provide evidence of long-term UHC financial risk protection. This study assessed financial risk protection as measured by the incidence of catastrophic health spending and impoverishment in Thai households prior to and after UHC in 2002.

METHODS

We used data from a 15-year series of annual national household socioeconomic surveys (SES) between 1996 and 2015, which were conducted by the National Statistic Office (NSO). The survey covered about 52,000 nationally representative households in each round. Descriptive statistics were used to assess the incidence of catastrophic payment as measured by the share of out-of-pocket payment (OOP) for health by households exceeding 10 and 25% of household total consumption expenditure, and the incidence of impoverishment as determined by the additional number of non-poor households falling below the national and international poverty lines after making health payments.

RESULTS

Using the 10% threshold, the incidence of catastrophic spending dropped from 6.0% in 1996 to 2% in 2015. This incidence reduced more significantly when the 25% threshold was applied from 1.8 to 0.4% during the same period. The incidence of impoverishment against the national poverty line reduced considerably from 2.2% in 1996 to approximately 0.3% in 2015. When the international poverty line of US$ 3.1 per capita per day was applied, the incidence of impoverishment was 1.4 and 0.4% in 1996 and 2015 respectively; and when US$ 1.9 per day was applied, the incidence was negligibly low.

CONCLUSION

The significant decline in the incidence of catastrophic health spending and impoverishment was attributed to the deliberate design of Thailand's UHC, which provides a comprehensive benefits package and zero co-payment at point of services. The well-founded healthcare delivery system and favourable benefits package concertedly support the achievement of UHC goals of access and financial risk protection.

Economic development and road traffic injuries and fatalities in Thailand: an application of spatial panel data analysis, 2012-2016

Background

Road traffic injuries (RTIs) have been one of the most critical public health problems in Thailand for decades. The objective of this study was to examine to what extent provincial economy was associated with RTIs, road traffic deaths and case fatality rate in Thailand.

Methods

A secondary data analysis on time-series data was applied. The unit of analysis was a panel of 77 provinces during 2012–2016. Data were obtained from relevant public authorities, including the Ministry of Public Health. Descriptive statistics and econometric models, using negative binomial (NB) regression, negative binomial regression with random-effects (RE) model, and spatial Durbin model (SDM) were employed. The main predictor variable was gross domestic product (GDP) per capita and the outcome variables were incidence proportion of RTIs, traffic deaths and case fatality rate. The analysis was adjusted for key covariates.

Results

The incidence proportion of RTIs rose from 449.0 to 524.9 cases per 100,000 population from 2012 till 2016, whereas the incidence of traffic fatalities fluctuated between 29.7 and 33.2 deaths per 100,000 population. Case fatality rate steadily stood at 0.06–0.07 deaths per victim. RTIs and traffic deaths appeared to be positively correlated with provincial economy in the NB regression and the RE model. In the SDM, a log-Baht increase in GDP per capita (equivalent to a growth of GDP per capita by about 2.7 times) enlarged the incidence proportion of injuries and deaths by about a quarter (23.8–30.7%) with statistical significance. No statistical significance was found in case fatality rate by the SDM. The SDM also presented the best model fitness relative to other models.

Conclusion

The incidence proportion of traffic injuries and deaths appeared to rise alongside provincial prosperity. This means that RTIs-preventive measures should be more intensified in economically well-off areas. Furthermore, entrepreneurs and business sectors that gain economic benefit in a particular province should share responsibility in RTIs prevention in the area where their businesses are running. Further studies that explore others determinants of road safety, such as patterns of vehicles used, attitudes and knowledge of motorists, investment in safety measures, and compliance with traffic laws, are recommended.

Association Between a Centrally Reimbursed Fee Schedule Policy and Access to Cataract Surgery in the Universal Coverage Scheme in Thailand

Importance

Uptake of cataract surgery in developing countries is much lower than that in developed countries. Cataract unawareness and financial barriers have been cited as the main causes. Under the Universal Coverage Scheme (UCS), Thailand introduced a central reimbursement (CR) system for cataract surgery. It is unknown if this financial arrangement could incentivize service provision (private or public) in areas that are hard to reach.

Objective

To examine the association between the CR policy and access to cataract surgery in Thailand.

Design, Setting, and Participants

Using time series analysis, hospitalization data during 2005 to 2015 for UCS members were analyzed for time trends and subnational variations in the cataract surgery rate (CSR) before and after the CR implementation.

Main Outcomes and Measures

The annual growth in access was estimated using segmented regression. The CSR gap across regions was determined by the slope index of inequality (SII). Unequal access across districts was represented by the gap between the top and bottom quintiles.

Results

During 2005 to 2015, a total of 0.98 million UCS members (mean [SD] age, 67.4 [11.2] years; 58.7% female) received cataract surgery. The number of cases increased from 77 897 in 2005 to 192 290 in 2015. At the national level, the CSR per 100 000 population increased from 352.0 to 378.7 cases in 2005 to 2008, to 716.3 cases in 2013, and then to 765.3 cases in 2015. With the use of mobile services through an exclusive CR, 3 private hospitals took the lead in service growth, sharing 79.2% of cases in the private sector in 2009. From 2010, the number of cases in public hospitals grew yearly by 12.6% to 13.6% until 2012, rose 21.7% in 2013, and then the rate of increase declined to that of 8.2% to 8.3% in 2014-2015. During the periods of an increase in overall access, the CSR gap across regions widened as indicated by the SII of 755.4 cases per 100 000 population in 2010 because of rapid uptake in areas with mobile services. When the national CSR became adequately large and mobile services were discouraged in 2013, the gap in 2014-2015 narrowed.

Conclusions and Relevance

This study found that the appropriate payment and service designs helped reduce the cataract surgery backlog. With an adequately high CSR, Thailand is on track to reach the VISION 2020 goal, aiming for blindness elimination by the year 2020, which has been achieved by most developed countries.

Budget impact analysis of the new reimbursement policy for day surgery in Thailand

Introduction

In 2017 the Thai Ministry of Public Health proposed a new financing mechanism to promote day surgery under the Universal Coverage Scheme – the main public insurance arrangement for Thais. The key feature of the policy is health facilities performing day surgery can claim the treatment expense based on relative weight (RW) instead of adjusted RW (adjRW). Procedures for 12 diseases (so-called “candidate procedures”) are eligible for the new reimbursement. The objective of this study was to assess the current day surgery situation in Thailand and analyze potential budget impact from the new policy.

Methods

A quantitative cross-section design was employed. Individual inpatient records of the Universal Coverage Scheme during 2014–2016 were analyzed. Descriptive statistics and simulation analyses were applied. The analyses were divided into three subtopics: 1) case volume and expense claim, 2) utilization across facilities, and 3) case mix index and budget impact.

Results

Overall, day surgery accounted for 4.8% of admissions with candidate procedures. Inguinal hernias, hemorrhoids, and common bile duct stones caused the largest sum of admission numbers and admission days. Currently, the annual reimbursement for candidate procedures treated as inpatient cases is around 290.8 million Baht (US$ 8.8 million), with about 12.4 million Baht (US$ 0.38 million) for day surgery cases. If all candidate procedures were performed as day surgery and diagnostic-related groups (DRG) version 6 was applied, the incremental budget would amount to 1.9 million Baht (US$ 58,903).

Conclusions

The new reimbursement policy will likely lead to minimal budget burden. Even in the case of maximal uptake of the policy, the needed budget would increase by just 15%. The marginal budget increment was explained by the infinitesimal RW–adjRW difference. Apart from the financial measure, other qualitative aspects of the policy, such as infrastructure and health staff readiness, should be explored.

Childhood stunting in Thailand: when prolonged breastfeeding interacts with household poverty

BACKGROUND

Childhood stunting, defined as the height-for-age standardized score lower than minus two, is one of the key indicators for assessing well-being and health of a child; and can be used for monitoring child health inequalities. Thailand has been successful in improving health and providing financial protection for its population. A better understanding of the determinants of stunting will help fill both knowledge and policy gaps which promote children's health and well-being. This study assesses the factors contributing to stunting among Thai children aged less than five years.

METHODS

This study obtained data from the Multiple Indicator Cluster Survey Round 4 (MICS4), conducted in Thailand in 2012. Data analysis consisted of three steps. First, descriptive statistics provided an overview of data. Second, a Chi-square test determined the association between each covariate and stunting. Finally, multivariable logistic regression assessed the likelihood of stunting from all independent variables. Interaction effects between breastfeeding and household economy were added in the multivariable logistic regression.

RESULTS

In the analysis without interaction effects, while the perceived size of children at birth as 'small' were positively associated with stunting, children in the well-off households were less likely to experience stunting. The analysis of the interactions between 'duration of breastfeeding' and 'household's economic level' found that the odds of stunting in children who were breastfed longer than 12 months in the poorest household quintile were 1.8 fold (95% Confidence interval: 1.3-2.6) higher than the odds found in mothers from the same poorest quintiles, but without prolonged breastfeeding. However prolonged breastfeeding in most well-off households (those between the second quintile and the fifth wealth quintile) did not show a tendency towards stunting.

CONCLUSIONS

Childhood stunting was significantly associated with several factors. Prolonged breastfeeding beyond 12 months when interacting with poor economic status of a household potentiated stunting. Children living in the least well-off households were more prone to stunting than others. We recommend that the MICS survey questionnaire be amended to capture details on quantity, quality and practices of supplementary feeding. Multi-sectoral nutrition policies targeting poor households are required to address stunting challenges.

Contributions of national and global health estimates to monitoring health-related Sustainable Development Goals in Thailand

The Millennium Development Goals (MDGs) triggered increased demand for data on child and maternal mortality for monitoring progress. With the advent of the Sustainable Development Goals (SDGs) and growing evidence of an epidemiological transition towards non-communicable diseases, policy makers need data on mortality and disease trends and distribution to inform effective policies and support monitoring progress. Where there are limited capacities to produce national health estimates (NHEs), global health estimates (GHEs) can fill gaps for global monitoring and comparisons. This paper draws lessons learned from Thailand’s burden of disease study (BOD) on capacity development for NHEs, and discusses the contributions and limitation of GHEs in informing policies at country level. Through training and technical support by external partners, capacities are gradually strengthened and institutionalized to enable regular updates of BOD at national and sub-national levels. Initially, the quality of cause of death reporting in the death certificates was inadequate, especially for deaths occurring in the community. Verbal autopsies were conducted, using domestic resources, to determine probable causes of deaths occurring in the community. This helped improve the estimation of years of life lost. Since the achievement of universal health coverage in 2002, the quality of clinical data on morbidities has also considerably improved. There are significant discrepancies between the 2010 Global Burden of Diseases (GBD) estimates for Thailand and the 1999 nationally generated BOD, especially for years of life lost due to HIV/AIDS, and the ranking of priority diseases. National ownership of NHEs and effective interfaces between researchers and decision makers contribute to enhanced country policy responses, while sub-national data are intended to be used by various sub-national-level partners. Though GHEs contribute to benchmarking country achievement compared with global health commitments, they may hamper development of NHE capacities. GHEs should encourage and support countries to improve their data systems and develop a data infrastructure that supports the production of empirical data needed to underpin estimation efforts.

How to do (or not to do) … a health financing incidence analysis

Financing incidence analysis (FIA) assesses how the burden of health financing is distributed in relation to household ability to pay (ATP). In a progressive financing system, poorer households contribute a smaller proportion of their ATP to finance health services compared to richer households. A system is regressive when the poor contribute proportionately more. Equitable health financing is often associated with progressivity. To conduct a comprehensive FIA, detailed household survey data containing reliable information on both a cardinal measure of household ATP and variables for extracting contributions to health services via taxes, health insurance and out-of-pocket (OOP) payments are required. Further, data on health financing mix are needed to assess overall FIA. Two major approaches to conducting FIA described in this article include the structural progressivity approach that assesses how the share of ATP (e.g. income) spent on health services varies by quantiles, and the effective progressivity approach that uses indices of progressivity such as the Kakwani index. This article provides some detailed practical steps for analysts to conduct FIA. This includes the data requirements, data sources, how to extract or estimate health payments from survey data and the methods for assessing FIA. It also discusses data deficiencies that are common in many low- and middle-income countries (LMICs). The results of FIA are useful in designing policies to achieve an equitable health system.

Financing for universal health coverage in small island states: evidence from the Fiji Islands

BACKGROUND

Universal health coverage (UHC) is critical to global poverty alleviation and equity of health systems. Many low-income and middle-income countries, including small island states in the Pacific, have committed to UHC and reforming their health financing systems to better align with UHC goals. This study provides the first comprehensive evidence on equity of the health financing system in Fiji, a small Pacific island state. The health systems of such states are poorly covered in the international literature.

METHODS

The study employs benefit and financing incidence analyses to evaluate the distribution of health financing benefits and burden across the public and private sectors. Primary data from a cross-sectional survey of 2000 households were used to assess healthcare benefits and secondary data from the 2008-2009 Fiji Household Income and Expenditure Survey to assess health financing contributions. These were analysed by socioeconomic groups to determine the relative benefit and financing incidence across these groups.

FINDINGS

The distribution of healthcare benefits in Fiji slightly favours the poor-around 61% of public spending for nursing stations and 26% of spending for government hospital inpatient care were directed to services provided to the poorest 20% of the population. The financing system is significantly progressive with wealthier groups bearing a higher share of the health financing burden.

CONCLUSIONS

The healthcare system in Fiji achieves a degree of vertical equity in financing, with the poor receiving a higher share of benefits from government health spending and bearing a lower share of the financing burden than wealthier groups.

System-wide analysis of health financing equity in Cambodia: a study protocol

BACKGROUND

To assess progress towards universal health coverage, countries like Cambodia require evidence on equity in the financing and distribution of healthcare benefits. This evidence must be based on a system-wide perspective that recognises the complex roles played by the public and private sectors in many contemporary healthcare systems.

OBJECTIVE

To undertake a system-wide assessment of who pays and who benefits from healthcare in Cambodia and to understand the factors influencing this.

METHODS

Financing and benefit incidence analysis will be used to calculate the financing burden and distribution of healthcare benefits across socioeconomic groups. Data on healthcare usage, living standards and self-assessed health status will be derived from a cross-sectional household survey designed for this study involving a random sample of 5000 households. This will be supplemented by secondary data from the Cambodian National Health Accounts 2014 and the Cambodian Socioeconomic Survey (CSES) 2014. We will also collect qualitative data through focus group discussions and in-depth interviews to inform the interpretation of the quantitative analyses.

POTENTIAL IMPACT

This study will produce previously unavailable information on who pays for, and who benefits from, health services across the entire health system of Cambodia. This evidence comes at a critical juncture in healthcare reform in South-East Asia with so many countries seeking guidance on the equity impact of their current financing arrangements that include a complex mix of public and private providers.

Impact of the health insurance scheme for stateless people on inpatient utilization in Kraburi Hospital, Thailand

Objectives

This study sought to investigate the impact of the Thai “Health Insurance for People with Citizenship Problems” (HI-PCP) on access to care for stateless patients, compared to Universal Coverage Scheme patients and the uninsured, using inpatient utilization as a proxy for impact.

Methods

Secondary data analysis of inpatient records of Kraburi Hospital, Ranong province, between 2009 (pre-policy) and 2012 (post-policy) was employed. Descriptive statistics and multivariate analysis by difference-in-difference model were performed.

Results

The volume of inpatient service utilization by stateless patients expanded after the introduction of the HI-PCP. However, this increase did not appear to stem from the HI-PCP per se. After controlling for key covariates, including patients’ characteristics, disease condition, and domicile, there was only a weak positive association between the HI-PCP and utilization. Critical factors contributing significantly to increased utilization were older age, proximity to the hospital, and presence of catastrophic illness.

Conclusion

A potential explanation for the insignificant impact of the HI-PCP on access to inpatient care of stateless patients is likely to be a lack of awareness of the existence of the scheme among the stateless population and local health staff. This problem is likely to have been accentuated by operational constraints in policy implementation, including the poor performance of local offices in registering stateless people. A key limitation of this study is a lack of data on patients who did not visit the health facility at the first opportunity. Further study of health-seeking behavior of stateless people at the household level is recommended.

Metformin for the treatment of gestational diabetes: An updated meta-analysis

OBJECTIVE

To assess the efficacy of metformin and insulin in the treatment of pregnant women with gestational diabetes mellitus (GDM).

METHODS

A meta-analysis was conducted by including randomized controlled trials comparing metformin and insulin in GDM. An electronic search was conducted to identify relevant studies. Data were synthesized by a random effects meta-analysis model. A Bayesian analysis was also performed to account for uncertainties in the treatment efficacy.

RESULTS

Eight clinical trials involving 1712 individuals were included in the final analysis. The pooled estimates of metformin-insulin differences were very small and statistically non-significant in fasting plasma glucose, postprandial plasma glucose and HbA1c, measured at 36-37 weeks of gestation. Notably, 14-46% of those receiving metformin required additional insulin. Compared with the insulin group, metformin treatment was associated with a lower incidence of neonatal hypoglycemia (relative risk, RR 0.74; 95% CI 0.58-0.93; P=0.01) and of neonatal intensive care admission (RR 0.76; 95% CI 0.59-0.97; P=0.03). Bayesian analysis revealed that the efficacy of metformin was consistently higher than insulin with a probability of over 98% on these two neonatal complications. Other outcomes were not significantly different between the two treatment groups.

CONCLUSION

In women with gestational diabetes, metformin use and insulin therapy have comparable glycemic control profile, but metformin use was associated with lower risk of neonatal hypoglycemia.

Assessment of equity in healthcare financing in Fiji and Timor-Leste: a study protocol

INTRODUCTION

Equitable health financing remains a key health policy objective worldwide. In low and middle-income countries (LMICs), there is evidence that many people are unable to access the health services they need due to financial and other barriers. There are growing calls for fairer health financing systems that will protect people from catastrophic and impoverishing health payments in times of illness. This study aims to assess equity in healthcare financing in Fiji and Timor-Leste in order to support government efforts to improve access to healthcare and move towards universal health coverage in the two countries.

METHODS AND ANALYSIS

The study employs two standard measures of equity in health financing increasingly being applied in LMICs-benefit incidence analysis (BIA) and financing incidence analysis (FIA). In Fiji, we will use a combination of secondary and primary data including a Household Income and Expenditure Survey, National Health Accounts, and data from a cross-sectional household survey on healthcare utilisation. In Timor-Leste, the World Bank recently completed a health equity and financial protection analysis that incorporates BIA and FIA, and found that the distribution of benefits from healthcare financing is pro-rich. Building on this work, we will explore the factors that influence the pro-rich distribution.

ETHICS AND DISSEMINATION

The study is approved by the Human Research Ethics Committee of University of New South Wales, Australia (Approval number: HC13269); the Fiji National Health Research Committee (Approval # 201371); and the Timor-Leste Ministry of Health (Ref MS/UNSW/VI/218).

RESULTS

Study outcomes will be disseminated through stakeholder meetings, targeted multidisciplinary seminars, peer-reviewed journal publications, policy briefs and the use of other web-based technologies including social media. A user-friendly toolkit on how to analyse healthcare financing equity will be developed for use by policymakers and development partners in the region.

Achieving universal health coverage goals in Thailand: the vital role of strategic purchasing

Strategic purchasing is one of the key policy instruments to achieve the universal health coverage (UHC) goals of improved and equitable access and financial risk protection. Given favourable outcomes of Universal Coverage Scheme (UCS), this study synthesized strategic purchasing experiences in the National Health Security Office (NHSO) responsible for the UCS in contributing to achieving UHC goals. The UCS applied the purchaser–provider split concept where NHSO, as a purchaser, is in a good position to enforce accountability by public and private providers to the UCS beneficiaries, through active purchasing. A comprehensive benefit package resulted in high level of financial risk protection as reflected by low incidence of catastrophic health spending and impoverished households. The NHSO contracted the District Health System (DHS) network, to provide outpatient, health promotion and disease prevention services to the whole district population, based on an annual age-adjusted capitation payment. In most cases, the DHS was the only provider in a district without competitors. Geographical monopoly hampered the NHSO to introduce a competitive contractual agreement, but a durable, mutually dependent relationship based on trust was gradually evolved, while accreditation is an important channel for quality improvement. Strategic purchasing services from DHS achieved a pro-poor utilization due to geographical proximity, where travel time and costs were minimal. Inpatient services paid by Diagnostic Related Group within a global budget ceiling, which is estimated based on unit costs, admission rates and admission profiles, contained cost effectively. To prevent potential under-provisions of the services, some high cost interventions were unbundled from closed end payment and paid on an agreed fee schedule. Executing monopsonistic purchasing power by NHSO brought down price of services given assured quality. Cost saving resulted in more patients served within a finite annual budget.

Constructing a state-transition model for an economic evaluation of cancer treatments

The paper gives an overview of the four fundamental elements that should be considered when constructing a Markov model of cancers, including outcome measures, health state transition, transitional probabilities, and model calibration. The construction of any model of this kind should begin by establishing transition to the death state. The probability of this transition can be estimated using overall survival data from clinical studies. Possible health states over a cycle are defined according to the natural history of diseases and treatment pathways. Validity of the constructed model is tested against real patient data and the parameters are adjusted until the survival results are consistent.

Sensitivity analysis for handling uncertainty in an economic evaluation

To meet updated international standards, this paper revises the previous Thai guidelines for conducting sensitivity analyses as part of the decision analysis model for health technology assessment. It recommends both deterministic and probabilistic sensitivity analyses to handle uncertainty of the model parameters, which are best represented graphically. Two new methodological issues are introduced-a threshold analysis of medicines' unit prices for fulfilling the National Lists of Essential Medicines' requirements and the expected value of information for delaying decision-making in contexts where there are high levels of uncertainty. Further research is recommended where parameter uncertainty is significant and where the cost of conducting the research is not prohibitive.

Health workforce contributions to health system development: a platform for universal health coverage

PROBLEM

In the 1970s, Thailand was a low-income country with poor health indicators and low health service coverage. The local health infrastructure was especially weak.

APPROACH

In the 1980s, measures were initiated to reduce geographical barriers to health service access, improve the health infrastructure at the district level, make essential medicines more widely available and develop a competent, committed health workforce willing to service rural areas. To ensure service accessibility, financial risk protection schemes were expanded.

LOCAL SETTING

In Thailand, district hospitals were practically non-existent in the 1960s. Expansion of primary health care (PHC), especially in poor rural areas, was considered essential for attaining universal health coverage (UHC). Nationwide reforms led to important changes in a few decades.

RELEVANT CHANGES

Over the past 30 years, the availability and distribution of health workers, as well as their skills and competencies, have greatly improved, along with national health indicators. Between 1980 and 2000 coverage with maternal and child health services increased substantially. By 2002, Thailand had attained UHC. Overall health system development, particularly an expanded health workforce, resulted in a functioning PHC system.

LESSONS LEARNT

A competent, committed health workforce helped strengthen the PHC system at the district level. Keeping the policy focus on the development of human resources for health (HRH) for an extended period was essential, together with a holistic approach to the development of HRH, characterized by the integration of different kinds of HRH interventions and the linking of these interventions with broader efforts to strengthen other health system domains.

Attitudes toward working in rural areas of Thai medical, dental and pharmacy new graduates in 2012: a cross-sectional survey

BACKGROUND

Inequity in health workforce distribution has been a national concern of the Thai health service for decades. The government has launched various policies to increase the distribution of health workforces to rural areas. However, little is known regarding the attitudes of health workers and the factors influencing their decision to work in rural areas. This study aimed to explore the current attitudes of new medical, dental and pharmacy graduates as well as determine the linkage between their characteristics and the preference for working in rural areas.

METHODS

A cross-sectional survey was conducted, using self-administered questionnaires, with a total of 1,225 medical, dental and pharmacy graduates. They were participants of the meeting arranged by the Ministry of Public Health (MOPH) on 1-2 April 2012. Descriptive statistics using mean and percentage, and inferential statistics using logistic regression with marginal effects, were applied for data analysis.

RESULTS

There were 754 doctors (44.4%), 203 dentists (42.6%) and 268 pharmacists (83.8%) enrolled in the survey. Graduates from all professions had positive views towards working in rural areas. Approximately 22% of doctors, 31% of dentists and 52% of pharmacists selected 'close proximity to hometown' as the most important reason for workplace selection. The multivariable analysis showed a variation in attributes associated with the tendency to work in rural areas across professions. In case of doctors, special track graduates had a 10% higher tendency to prefer rural work than those recruited through the national entrance examination.

CONCLUSIONS

The majority of graduates chose to work in community hospitals, and attitudes towards rural work were quite positive. In-depth analysis found that factors influencing their choice varied between professions. Special track recruitment positively influenced the selection of rural workplaces among new doctors attending the MOPH annual meeting for workplace selection. This policy innovation should be applied to dentists and pharmacists as well. However, implementing a single policy without supporting strategies, or failing to consider different characteristics between professions, might not be effective. Future study of attitudes and factors contributing to the selection of, and retention in, rural service of both new graduates and in-service professionals was recommended.

Good Health at Low Cost 25 years on: lessons for the future of health systems strengthening

In 1985, the Rockefeller Foundation published Good health at low cost to discuss why some countries or regions achieve better health and social outcomes than do others at a similar level of income and to show the role of political will and socially progressive policies. 25 years on, the Good Health at Low Cost project revisited these places but looked anew at Bangladesh, Ethiopia, Kyrgyzstan, Thailand, and the Indian state of Tamil Nadu, which have all either achieved substantial improvements in health or access to services or implemented innovative health policies relative to their neighbours. A series of comparative case studies (2009-11) looked at how and why each region accomplished these changes. Attributes of success included good governance and political commitment, effective bureaucracies that preserve institutional memory and can learn from experience, and the ability to innovate and adapt to resource limitations. Furthermore, the capacity to respond to population needs and build resilience into health systems in the face of political unrest, economic crises, and natural disasters was important. Transport infrastructure, female empowerment, and education also played a part. Health systems are complex and no simple recipe exists for success. Yet in the countries and regions studied, progress has been assisted by institutional stability, with continuity of reforms despite political and economic turmoil, learning lessons from experience, seizing windows of opportunity, and ensuring sensitivity to context. These experiences show that improvements in health can still be achieved in countries with relatively few resources, though strategic investment is necessary to address new challenges such as complex chronic diseases and growing population expectations.

Prevalence and profiles of unmet healthcare need in Thailand

BACKGROUND

In the light of the universal healthcare coverage that was achieved in Thailand in 2002, policy makers have raised concerns about whether there is still unmet need within the population. Our objectives were to assess the annual prevalence, characteristics and reasons for unmet healthcare need in the Thai population in 2010 and to compare our findings with relevant international literature.

METHODS

A standard set of OECD unmet need questionnaires was used in a nationally-representative household survey conducted in 2010 by the National Statistical Office. The prevalence of unmet need among respondents with various socio-economic characteristics was estimated to determine an inequity in the unmet need and the reasons behind it.

RESULTS

The annual prevalence of unmet need for outpatient and inpatient services in 2010 was 1.4% and 0.4%, respectively. Despite this low prevalence, there are inequities with relatively higher proportion of the unmet need among Universal Coverage Scheme members, and the poor and rural populations. There was less unmet need due to cost than there was due to geographical barriers. The prevalence of unmet need due to cost and geographical barriers among the richest and poorest quintiles were comparable to those of selected OECD countries. The geographical extension of healthcare infrastructure and of the distribution of health workers is a major contributing factor to the low prevalence of unmet need.

CONCLUSIONS

The low prevalence of unmet need for both outpatient and inpatient services is a result of the availability of well-functioning health services at the most peripheral level, and of the comprehensive benefit package offered free of charge by all health insurance schemes. This assessment prompts a need for regular monitoring of unmet need in nationally-representative household surveys.

Why has the Universal Coverage Scheme in Thailand achieved a pro-poor public subsidy for health care?

BACKGROUND

Thailand has achieved universal health coverage since 2002 through the implementation of the Universal Coverage Scheme (UCS) for 47 million of the population who were neither private sector employees nor government employees. A well performing UCS should achieve health equity goals in terms of health service use and distribution of government subsidy on health. With these goals in mind, this paper assesses the magnitude and trend of government health budget benefiting the poor as compared to the rich UCS members.

METHOD

Benefit incidence analysis was conducted using the nationally representative household surveys, Health and Welfare Surveys, between 2003 and 2009. UCS members are grouped into five different socio-economic status using asset indexes and wealth quintiles.

FINDINGS

The total government subsidy, net of direct household payment, for combined outpatient (OP) and inpatient (IP) services to public hospitals and health facilities provided to UCS members, had increased from 30 billion Baht (US$ 1 billion) in 2003 to 40-46 billion Baht in 2004-2009. In 2003 for 23% and 12% of the UCS members who belonged to the poorest and richest quintiles of the whole-country populations respectively, the share of public subsidies for OP service was 28% and 7% for the poorest and the richest quintiles, whereby for IP services the share was 27% and 6% for the poorest and richest quintiles respectively. This reflects a pro-poor outcome of public subsidies to healthcare. The OP and IP public subsidies remained consistently pro-poor in subsequent years.The pro-poor benefit incidence is determined by higher utilization by the poorest than the richest quintiles, especially at health centres and district hospitals. Thus the probability and the amount of household direct health payment for public facilities by the poorest UCS members were less than their richest counterparts.

CONCLUSIONS

Higher utilization and better financial risk protection benefiting the poor UCS members are the results of extensive geographical coverage of health service infrastructure especially at district level, adequate finance and functioning primary healthcare, comprehensive benefit package and zero copayment at points of services.

Economic evaluation of policy options for prevention and control of cervical cancer in Thailand

BACKGROUND

The Thai healthcare setting has seen patients with cervical cancer experience an increasing burden of morbidity and mortality, a stagnation in the performance of cervical screening programmes and the introduction of a vaccine for the prevention of human papillomavirus (HPV) infection.

OBJECTIVE

This study aims to identify the optimum mix of interventions that are cost effective, from societal and healthcare provider perspectives, for the prevention and control of cervical cancer.

METHODS

A computer-based Markov model of the natural history of cervical cancer was used to simulate an age-stratified cohort of women in Thailand. The strategy comparators, including both control and prevention programmes, were (i) conventional cytology screening (Pap smears); (ii) screening by visual inspection with acetic acid (VIA); and (iii) HPV-16, -18 vaccination. Input parameters (e.g. age-specific incidence of HPV infection, progression and regression of the infection, test performance of screening methods and efficacy of vaccine) were synthesized from a systematic review and meta-analysis. Costs (year 2007 values) and outcomes were evaluated separately, and compared for each combination. The screening strategies were started from the age of 30-40 years and repeated at 5- and 10-year intervals. In addition, HPV vaccines were introduced at age 15-60 years.

RESULTS

All of the screening strategies showed certain benefits due to a decreased number of women developing cervical cancer versus 'no intervention'. Moreover, the most cost-effective strategy from the societal perspective was the combination of VIA and sequential Pap smear (i.e., VIA every 5 years for women aged 30-45 years, followed by Pap smear every 5 years for women aged 50-60 years). This strategy was dominant, with a QALY gain of 0.01 and a total cost saving of Baht (Bt) 800, compared with doing nothing. From the societal perspective, universal HPV vaccination for girls aged 15 years without screening resulted in a QALY gain of 0.06 at an additional cost of Bt 8,800, based on the cost of Bt 15,000 for a full immunization schedule. The incremental cost-effectiveness ratio, comparing HPV vaccinations for girls aged 15 years with the current national policy of Pap smears for women aged 35-60 years every 5 years, was approximately Bt 18,1000 per QALY gained. This figure was relatively high for the Thai setting.

CONCLUSIONS

The results suggest that controlling cervical cancer by increasing the numbers of women accepting the VIA and Pap smear screening as routine and by improving the performance of the existing screening programmes is the most cost-effective policy option in Thailand.

Equity of access to and utilization of reproductive health services in Thailand: national Reproductive Health Survey data, 2006 and 2009

This study assessed trends in equity of access to reproductive health services and service utilization in terms of coverage of family planning, antenatal care and skilled birth attendance in Thailand. Two health indicators were measured: the prevalence of low birthweight and exclusive breastfeeding. Equity was measured against the combined urban-rural areas and geographic regions, women's education level and quintiles of household assets index. The study used data from two nationally representative household surveys, the 2006 and 2009 Reproductive Health Surveys. Very high coverage of family planning (79.6%), universal antenatal care (98.9%) and skilled birth attendance (99.7%), with very small socioeconomic and geographic disparities, were observed. The public sector played a dominant role in maternity care (90.9% of all deliveries in 2009). The private sector also had a role among the higher educated, wealthier women living in urban areas. Public sector facilities, followed by drug stores, were a major supplier of contraception, which had a high use rate. High coverage and low inequity were the result of extensive investment in the health system by successive governments, in particular primary health care at district and sub-district levels, reaching universality by 2002. While maintaining these achievements, methodological improvements in measuring low birthweight and exclusive breastfeeding for future reproductive health surveys are recommended.

Trends and inequities in where women delivered their babies in 25 low-income countries: evidence from Demographic and Health Surveys

In low-income countries, the coverage of institutional births is low. Using data from the two most recent Demographic and Health Surveys (1995-2001 and 2001-2006) for 25 low-income countries, this study examined trends in where women delivered their babies--public or private facilities or non-institutional settings. More than half of deliveries were in institutional settings in ten countries, mostly public facilities. In the other 15 countries, the majority of births were in women's homes, which was often their only option. Between the two survey periods, all five Asian countries studied (except Bangladesh) had an increase of 10-20 percentage points in institutional coverage, whereas none of the 19 sub-Saharan African countries saw an increase of more than 10 percentage points. More urban women and more in the richest (least poor) quintile gave birth in public or private facilities than rural and poorest quintile women. The rich-poor gap of institutional births was wider than the urban-rural gap. Inadequate public investment in health system infrastructure in rural areas and lack of skilled health professionals are major obstacles in reducing maternal mortality. Governments in low-income countries must invest more, especially in rural maternity services. Strengthening private, for-profit providers is not a policy choice for poor, rural communities.

Equity in maternal and child health in Thailand

OBJECTIVE

To assess equity in health outcomes and interventions for maternal and child health (MCH) services in Thailand.

METHODS

Women of reproductive age in 40 000 nationally representative households responded to the Multiple Indicator Cluster Survey in 2005-2006. We used a concentration index (CI) to assess distribution of nine MCH indicator groups across the household wealth index. For each indicator we also compared the richest and poorest quintiles or deciles, urban and rural domiciles, and mothers or caregivers with or without secondary school education.

FINDINGS

CHILD UNDERWEIGHT (CI: -0.2192; P < 0.01) and stunting (CI: -0.1767; P < 0.01) were least equitably distributed, being disproportionately concentrated among the poor; these were followed by teenage pregnancy (CI: -0.1073; P < 0.01), and child pneumonia (CI: -0.0896; P < 0.05) and diarrhoea (CI: -0.0531; P < 0.1). Distribution of the MCH interventions was fairly equitable, but richer women were more likely to receive prenatal care and delivery by a skilled health worker or in a health facility. The most equitably distributed interventions were child immunization and family planning. All undesirable health outcomes were more prevalent among rural residents, although the urban-rural gap in MCH services was small. Where mothers or caregivers had no formal education, all outcome indicators were worse than in the group with the highest level of education.

CONCLUSION

Equity of coverage in key MCH services is high throughout Thailand. Inequitable health outcomes are largely due to socioeconomic factors, especially differences in the educational level of mothers or caregivers.

The equity impact of the universal coverage policy: lessons from Thailand

OBJECTIVE

This chapter assesses health equity achievements of the Thai health system before and after the introduction of the universal coverage (UC) policy. It examines five dimensions of equity: equity in financial contributions, the incidence of catastrophic health expenditure, the degree of impoverishment as a result of household out-of-pocket payments for health, equity in health service use and the incidence of public subsidies for health.

METHODOLOGY

The standard methods proposed by O'Donnell, van Doorslaer, and Wagstaff (2008b) were used to measure equity in financial contribution, healthcare utilization and public subsidies, and in assessing the incidence of catastrophic health expenditure and impoverishment. Two major national representative household survey datasets were used: Socio-Economic Surveys and Health and Welfare Surveys.

FINDINGS

General tax was the most progressive source of finance in Thailand. Because this source dominates total financing, the overall outcome was progressive, with the rich contributing a greater share of their income than the poor. The low incidence of catastrophic health expenditure and impoverishment before UC was further reduced after UC. Use of healthcare and the distribution of government subsidies were both pro-poor: in particular, the functioning of primary healthcare (PHC) at the district level serves as a "pro-poor hub" in translating policy into practice and equity outcomes.

POLICY IMPLICATIONS

The Thai health financing reforms have been accompanied by nationwide extension of PHC coverage, mandatory rural health service by new graduates and systems redesign, especially the introduction of a contracting model and closed-ended provider payment methods. Together, these changes have led to a more equitable and more efficient health system. Institutional capacity to generate evidence and to translate it into policy decisions, effective implementation and comprehensive monitoring and evaluation are essential to successful system-level reforms.

Assessing the efficiency of hospital pharmacy services in Thai public district hospitals

The purpose of this study was to assess the efficiency of hospital pharmacy services and to determine the environmental factors affecting pharmacy service efficiency. The technical efficiency of a hospital pharmacy was assessed to evaluate the hospital's ability to use pharmacy manpower in order to produce the maximum output of the pharmacy service. Data Envelopment Analysis (DEA) was used as an efficiency measurement. The two labor inputs were pharmacists and support personnel and the ten outputs were from four pharmacy activities: drug dispensing, drug purchasing and inventory control, patient-oriented activities, and health consumer protection services. This was used to estimate technical efficiency. A Tobit regression model was used to determine the effect of the hospital size, location, input mix of pharmacy staff, working experience of pharmacists at the study hospitals, and use of technology on the pharmacy service efficiency. Data for pharmacy service input and output quantities were obtained from 155 respondents. Nineteen percent were found to have full efficiency with a technical efficiency score of 1.00. Thirty-six percent had a technical efficiency score of 0.80 or above and 27% had a low technical efficiency score (< 0.60). The average TE score increased in respect to the hospital size (0.60, 0.71, 0.75, and 0.83 in 10, 30, 60, and 90-120 bed hospitals, respectively). Hospital size and geographic location were significantly associated with pharmacy service efficiency.

Handling uncertainty of the economic evaluation result: sensitivity analysis

An economic evaluation of health technology and interventions often comes with uncertainty in the parameters that were used in the model. To determine sensitivity of the result obtained from a reference case analysis, researchers can employ deterministic and probabilistic approaches. This methodological guideline summarizes the principles underlying the sensitivity analysis and recommends that the probabilistic sensitivity analysis is the best method to handle the parameter uncertainty.

Catastrophic and poverty impacts of health payments: results from national household surveys in Thailand

OBJECTIVE

To estimate the incidence and describe the profile of catastrophic expenditures and impoverishment due to household out-of-pocket payments, comparing the periods before and after the introduction of universal health care coverage (UC).

METHODS

Secondary data analyses of socioeconomic surveys on nationally representative households pre-UC in 2000 (n = 24,747) and post-UC in 2002 (n = 34,785) and 2004 (n = 34,843).

FINDINGS

Households using inpatient care experienced catastrophic expenditures most often (31.0% in 2000, compared with 15.1% and 14.6% in 2002 and 2004, respectively). During the two post-UC periods, the incidence of catastrophic expenditures for inpatient services at private hospitals was 32.1% for 2002 and 27.8% for 2004. For those using inpatient care at district hospitals, the corresponding catastrophic expenditures figures were 6.5% and 7.3% in 2002 and 2004, respectively. The catastrophic expenditures incidence for outpatient services from private hospitals moved from 27.9% to 28.5% between 2002 and 2004. In 2000, before universal coverage was introduced, the percentages of Thai households who used private hospitals and faced catastrophic expenditures were 35.8% for inpatient care and 36.0% for outpatient care. Impoverishment increased for poor households because of payments for inpatient services by 84.0% in 2002, by 71.5% in 2004 and by 95.6% in 2000. The relative increase in out-of-pocket impoverishment was found in 98.8% to 100% of those who were poor following payments made to private hospitals, regardless of type of care.

CONCLUSION

Households using inpatient services, especially at private hospitals, were more likely to face catastrophic expenditures and impoverishment from out-of-pocket payments. Use of services not covered by the UC benefit package and bypassing the designated providers (prohibited under the capitation contract model without proper referrals) are major causes of catastrophic expenditures and impoverishment.

Efficacy of dexamethasone injection for acute bronchiolitis in hospitalized children: a randomized, double-blind, placebo-controlled trial

Controversy over the efficacy of systemic corticosteroids for acute bronchiolitis initiated this study. We conducted a randomized, double-blind, placebo-controlled trial to examine the efficacy of single dexamethasone injection for the treatment of acute bronchiolitis in young hospitalized children. The study, performed at the pediatric wards of a University Hospital and its affiliated hospital in Thailand, included 174 previously healthy children under 2 years of age, hospitalized with acute bronchiolitis. Each child received either a single intramuscular injection of 0.6 mg/kg dexamethasone or a placebo in addition to regular management. The primary outcome was the time from study entry to resolution of respiratory distress, determined by a clinical score derived from the respiratory rate, occurrence of wheezing, chest retraction, and oxygen saturation. Survival analysis using the Kaplan-Meier method and a log-rank test were performed. A single-dose, dexamethasone injection versus placebo produced a significant: (1) decrease in the time needed for resolution of respiratory distress (hazard ratio 1.56; 95% CI, 1.14-2.13; P = 0.005), (2) decrease in the mean duration of symptoms of 11.8 hr (95% CI, 3.9-19.7; P = 0.004), (3) decrease in the mean duration of oxygen therapy of 14.9 hr (95% CI, 5.3-24.4; P = 0.003), and (4) decrease in the mean length of hospital stay of 13.4 hr (95%CI, 2.6-24.2; P = 0.02). In conclusion, a single injection of dexamethasone yielded a significant clinical benefit for the treatment of previously healthy, young children hospitalized with acute bronchiolitis.

The validity of A new practical quality of life measure in patients on renal replacement therapy

OBJECTIVE

A new quality of life measure, apart of the National Health and Welfare 2003 survey, is a promising tool for outcome evaluation of clinical practice due to its brevity, validity, reliability, and providing easy interpretation against general population norm-based scores. The measure consisting of 9-items, and so called 9-item Thai Health status Assessment Instrument (9-THAI) was used to assess its validity and reliability in patients on renal replacement therapy (RRT).

MATERIAL AND METHOD

Three hundred and two patients on RRT who visited Srinagarind Hospital from March to May 2005 were studied Convergent and divergent validity were assessed using SF-36 as the concurrent measure. Concurrent validity was also assessed using hematocrit level and hospitalization history in the last year as concurrent clinical measures. Test-retest reliability was studied by repeated measure within one 1 month. Responsiveness of 9-THAI was studied in patients who reported health improvement.

RESULTS

Results of correlations between 9-THAI and SF-36 domains were as hypothesized 9-THAI scores were significantly correlated with hematocrit level and hospitalization history. The results confirmed the validity of 9-THAI for use as a quality of life measure. Intraclass correlation coefficients of 9-THAI scores in stable patients were satisfactory. Among patients on RRT who reported overall health improvement, 9-THAI scores significantly increased, thus adding further evidence of the responsiveness of 9-THAI.

CONCLUSION

The 9-THAI is a valid and reliable generic health status measure that can be used as an ideal core in a battery of quality of life measures in clinical practice for patients on RRT.

Cost-effectiveness analysis of sequential paclitaxel adjuvant chemotherapy for patients with node positive primary breast cancer

An economic evaluation of paclitaxel added subsequently to doxorubicin plus cyclophosphamide (AC) adjuvant therapy for early breast cancer with lymph nodes positive is presented. Health care cost associated with AC alone vs. AC with paclitaxel was compared under Thai health care context. Based on CALGB9344, paclitaxel increased the disease-free survival (DFS) by 17%. Based on Markov simulation for 15 years, paclitaxel prolonged the patient's life by 0.30 quality-adjusted life years (QALY). Such an increased effectiveness was offset by the adjuvant cost net of recurrence, follow-up, and terminal care by 221,433 Baht. This means an additional year of perfect health gained by paclitaxel is achieved through an incremental cost of 738,111 Baht. Such an incremental cost-effectiveness ratio (ICER) is beyond the threshold recommended by World Health Organization. In women with negative estrogen receptor that DFS was improved to 28%, the ICER of paclitaxel was reduced to 393,984 Baht per QALY.

Effect of changes in diagnosis and management of active infective endocarditis on the clinical outcome at Srinagarind Hospital

BACKGROUND

In recent years, diagnostic methods and treatment of infective endocarditis (IE) have been improved. It is not known whether the clinical outcome is any better.

OBJECTIVE

To assess the effect of changes on the clinical outcomes of IE patients.

MATERIAL AND METHOD

The authors performed a retrospective study comparing IE patients hospitalized at Srinagarind hospital during the period from 1/1/1990 to 31/12/2002. The authors classified the patients according to the period of diagnosed from 1990 to 1993 (n=57), 1994 to1997 (n=71), and 1998 to 2002 (n=72) cohorts.

RESULTS

There were two hundred IE patients in the present study. Mean age and degenerative heart disease were increasing. Operative and in-hospital mortality were decreasing. Overall survival rate was 81% at the first year 60% at 5 years, 55% at 12 years in surgically treated patients, with 30-day mortality in 27.1% mostly from the 1990 to 1993 cohort. In medically treated IE, overall the survival rate was 37% in the first year, 32% at 5 years, 20% at 12 years, with 30-day mortality in 72.86% mostly in the 1990 to 1993 cohort. Early surgical intervention, improved long-term survival rates (hazard ratio 0.23; 95% CI 0.14-0.37), severe congestive heart failure (hazard ratio 1.87; 95% CI 1.17-2.99) and renal failure (hazard ratio 4.10; 95% CI 2.05-7.84) are the predictors of mortality by multivariate analysis. Survival rate from 1998 to 2002 cohort was 85%, 1994 to 1997 cohort was 54% and 1993 to 1990 cohort was 27% at 1-year (p < 0.001).

CONCLUSION

The data indicated that the changing clinical outcome of this disease, reflected improvements in diagnostic method and treatment. Although IE remains a serious condition characterized by significant morbidity and mortality, the overall survival rate has significantly improved over time. The authors therefore, believe that early diagnosis and prompt treatment both medical or surgical interventions will improve the outcome of IE patients.

Clinical outcome of native valve infective endocarditis in Khon Kaen: 1990-1999

OBJECTIVE

To compare the survival of infective endocarditis (IE) patients following different treatment strategies and to determine the predictors of patient survival.

BACKGROUND

IE is a life-threatening infectious disease that is often difficult to manage. Studies on long-term outcome are limited.

METHOD

Data on 152 patients with IE from 1990 to 1999 were collected from two hospitals. The main outcome is death after definite diagnosis of native valve IE.

RESULTS

The overall case fatality rate was 38 per 100 patient-years. Survival curves showed better survival for patients treated with surgery compared with patients treated medically (p <0.0001). Survival rate at year 1 was 72 per cent for surgically treated patients and 33 per cent for medically treated patients. Five-year survival rates were 66 per cent and 27 per cent in the two groups, respectively. Based on Cox proportional hazards regression analysis, surgery to be an independent predictor of survival (relative risk [RR] = 0.23; 95% confidence interval [CI] 0.14 to 0.39, p < 0.0001), while the presence of congestive heart failure (RR = 2.55; 95% CI 1.61 to 4.02, p < 0.0001), and being male (RR = 1.76; 95% CI 1.04 to 2.82, p <0.05) were independent predictors of mortality.

CONCLUSION

Patients with native valve endocarditis have a high long-term mortality rate. The most common types of cardiac death are post-operative and sudden death. Surgical treatment was the preventive factor of mortality.
