Present status of renal replacement therapy in Asian countries as of 2016: Cambodia, Laos, Mongolia, Bhutan, and Indonesia

Present status of renal replacement therapy in lower-middle-income Asian countries: Cambodia, Myanmar, Laos, Vietnam, Mongolia, and Bhutan as of June 2019 (before COVID-19), from the interviews of leading doctors in every country: (duplicated English publication from “the special Japanese edition of educational lectures in the 64th annual meeting of the Japanese Society for Dialysis Therapy”)

The present status of Cambodia, Myanmar, Laos, Vietnam, Mongolia, and Bhutan as of June 2019 was reviewed from the interviews of leading doctors in every country. The timing was until just 6 months before the COVID-19 pandemic broke out. The cost per hemodialysis session was 25–70 US dollar and expensive if it is compared with average monthly income of every country. In Cambodia and Laos, patients must cover 100% of expenses for maintenance hemodialysis, in Myanmar, the government covers the cost of once-weekly dialysis sessions, in Vietnam, the government covers 80% of the cost, and in Mongolia and Bhutan, the cost is fully covered by the government. Continuous ambulatory peritoneal dialysis was widely available in Vietnam and Mongolia, which have achieved a relative standard of social infrastructure, but is far from common in any of the other countries. The number of patients on dialysis is increasing with economic development in all countries. Diabetic nephropathy is a common primary reason for dialysis. None of the countries discussed in this article had clinical engineers who could maintain hemodialysis equipment and carry out clinical tasks in dialysis centers. Hospitals were not maintaining their equipment, and damaged units were kept in storage to be used for spare parts. None of the countries had dieticians to provide patients with dietary guidance. Establishment and training of both clinical engineers and registered dietitians are major projects that must be undertaken.

The influence of the National Health Insurance scheme of the Lao People's Democratic Republic on healthcare access and catastrophic health expenditures for patients with chronic renal disease, and the possibility of integrating organ transplantation into the health financing system

Citizens of the Lao People’s Democratic Republic have difficulties in obtaining proper health services compared to more developed countries, due to the lack of available health facilities and health financing programmes. Haemodialysis (HD) is currently included under the coverage of the National Health Insurance (NHI) scheme. However, there are several technical barriers related to health service utilization. This study aims to analyse the effects of the Lao NHI on issues of accessibility and the possibility of encountering catastrophic health expenditures for patients with chronic kidney disease. In addition, the study provides policy recommendations for policy-makers regarding the provision of organ transplantation under NHI in the future. Savannakhet Province was purposively selected as a study site, where 342 respondents participated in the study. Two logistic regression models are used to assess the effectiveness of the NHI in terms of accessibility and financial protection against catastrophic health expenditures. The Andersen behavioural model is applied as a guideline to identify factors that affect accessibility and economic catastrophe. NHI is found to improve accessibility to health service utilization for household members with chronic kidney disease. However, due to the limited HD services, there are barriers to accessing health services and a risk of financial hardship due to nonmedical expenditures. Chronic conditions, in addition to kidney issues, dramatically increase the chances of suffering catastrophic health expenditures. In the short run, collaboration with neighbouring countries’ hospitals through copayment programmes is strongly recommended for NHI’s policy-makers. For long-term policy guidelines, the government should move forward to include kidney transplantation in the NHI healthcare system.

Clinical outcomes and performance indicators of patients with Kidney Failure and Acute Kidney Injuries in ASEAN countries

INTRODUCTION

This review article reports clinical outcomes and performance indicators of patients with Kidney Failure (KF) and Acute Kidney Injuries (AKI) in Association of South East Asian Nations (ASEAN) countries.

METHODOLOGY

ASEAN data, segregated by income status, from national registries and literature were collated, compared and benchmarked against international references.

RESULTS

The national incidence and prevalence of treated KF ranged from 172-479 per million population (pmp) and 36-2255 pmp respectively. Brunei (79%), Malaysia (66%) and Singapore (66%) had world-leading proportions of diabetes-related KF. Haemodialysis (HD), Peritoneal Dialysis (PD) and transplant accounted for 68-100%, 0-27% and 0-18% of all Kidney Failure Replacement Therapy respectively. Transplant patient survival were superior with 90-93% at five years and 71-90% at 10 years, compared to PD (44-54%) and HD (53-64%) at five years. Higher-income countries were able to achieve good anaemia control, HD and PD adequacy targets, whilst usage of arteriovenous fistula in HD varied from 70-85%. Acute Kidney Injury (AKI) rates ranged from 24.2-49.2% of high-dependency admissions. Lower incidences of PD peritonitis and HD Catheter-related Bloodstream Infections; and PD-favouring quality-of-life were evident in higher-income countries.

CONCLUSION

ASEAN has a challenging burden of kidney disease, with extremely high incidence, prevalence, DM-related KF and AKI rates. The magnitude of the prevailing problem calls for the creation of a regional society under the auspices of ASEAN with a shared perspective of universal, equitable and charitable access to quality renal care; consistent with the founding premises and healthcare initiatives of ASEAN.

Current status of renal replacement therapy in Cambodia and Japanese support activities in developing countries in East and Southeast Asia: a report as of June 2018 from the Non-Western World Countries Symposium at the 63rd Annual Meeting of the Japanese Society for Dialysis Therapy

Since 2015, the Committee of International Communication for Academic Research of the Japanese Society for Dialysis Therapy has held a symposium every year at the society’s Annual Congress to discuss the current status of and demand for dialysis therapy in developing countries in Asia with the aim of identifying ways to contribute to the field of dialysis therapy in these countries. The 2018 symposium opened the door further, beyond Asian countries to include all non-Western countries. Two speakers from Cambodia and Japan contributed their manuscripts to the 2018 symposium issue. In Cambodia in 2017, a study of hemodialysis data from 5 centers in Phnom Penh was conducted for the first time. This study involving 407 patients (233 men [57.2%]; mean age 52 [SD, ± 15] years) revealed that hypertension was the main cause of end-stage renal disease (46.8%), followed by concomitant hypertension and diabetes mellitus (31%), with diabetes mellitus alone accounting for only 8.1% of cases. Mean frequency of hemodialysis was 7.5 (SD, ± 2.3) sessions per month. The duration of each session was 4 h. Patients in Cambodia are required to bear the full cost for hemodialysis because the country lacks a national health insurance system. From 2007 to 2018, several Japanese societies and organizations for dialysis therapy and technology carried out activities aimed at resolving problems in dialysis medical care in developing countries in East and Southeast Asia. The role of the academic societies and their activities in this region are discussed.

Missing In-Center Hemodialysis Sessions among Patients with End Stage Renal Disease in Banda Aceh, Indonesia

Indonesian universal health coverage was implemented in 2013 and hemodialysis services became universally accessible, yet few studies have examined patient adherence to hemodialysis schedules. We examined the rates of missed in-center hemodialysis sessions in Banda Aceh and the factors associated with non-attendance. This cross-sectional questionnaire survey included 193 patients receiving in-center hemodialysis. Approximately 28% of the patients missed ≥ 1 hemodialysis session in the month prior to the questionnaire’s administration. About 65% reported attending religious activities as the reason for missing hemodialysis. The level of health literacy was generally low with a mean score of 14.38 out of 26 (55.3%). Multivariate logistic regression analyses showed that patients with educational levels higher than elementary school were less likely to miss hemodialysis sessions. Participants who performed more self-care behaviors had lower odds of missing hemodialysis sessions. Every unit increase in the health literacy score was associated with increased odds of missing hemodialysis sessions. Emphasizing the importance of attending hemodialysis sessions and modifying hemodialysis schedules based on patients’ needs is essential. Patients who miss hemodialysis sessions should be reminded of all self-care behaviors. Health literacy among hemodialysis patients should be improved, with emphasis on patient safety, advanced knowledge, and critical health literacy.

Peritoneal dialysis in Indonesia: Current status, challenges and prospects

Despite an increase in incident peritoneal dialysis (PD) use of 20% per year, the overall PD prevalence in Indonesia is only 1-2%, with the goal of 30% yet to be reached by 2019. In the absence of contraindications, increasing continuous ambulatory PD (CAPD) use may be an attractive option for Indonesia to reduce the high costs of end-stage kidney disease (ESKD) treatment. The implementation of CAPD in Indonesia faces several challenges, including the cost of PD, the unique archipelagic geography, limited facilities and trained medical personnel in rural areas, inadequate reimbursement rates and incentive fees, high rates of PD discontinuation, as well as insufficient knowledge regarding CAPD by the general public and health professionals. Changes in the policy of medical service incentive fees and improvements in the national health insurance system regulation over CAPD may improve the utilization of PD for ESKD patients in Indonesia. Nationwide promotional and preventive efforts on chronic kidney disease, dialysis modality education and establishment of PD training programs for medical professionals are necessary.

Temporal changes and risk factors of death from early withdrawal within 12 months of dialysis initiation - a cohort study

Background

Mortality risk is high soon after dialysis initiation in patients with kidney failure, and dialysis withdrawal is a major cause of early mortality, attributed to psychosocial or medical reasons. The temporal trends and risk factors associated with cause-specific early dialysis withdrawal within 12 months of dialysis initiation remain uncertain.

Methods

Using data from the Australia and New Zealand Dialysis and Transplant Registry, we examined the temporal trends and risk factors associated with mortality attributed to early psychosocial and medical withdrawals in incident adult dialysis patients in Australia between 2005 and 2018 using adjusted competing risk analyses.

Results

Of 32 274 incident dialysis patients, 3390 (11%) experienced death within 12 months post-dialysis initiation. Of these, 1225 (36%) were attributed to dialysis withdrawal, with 484 (14%) psychosocial withdrawals and 741 (22%) medical withdrawals. These patterns remained unchanged over the past two decades. Factors associated with increased risk of death from early psychosocial and medical withdrawals were older age, dialysis via central venous catheter, late referral and the presence of cerebrovascular disease; obesity and Asian ethnicity were associated with decreased risk. Risk factors associated with early psychosocial withdrawals were underweight and higher socioeconomic status. Presence of peripheral vascular disease, chronic lung disease and cancers were associated with early medical withdrawals.

Conclusions

Death from dialysis withdrawal accounted for >30% of early deaths in kidney failure patients initiated on dialysis and remained unchanged over the past two decades. Several shared risk factors were observed between mortality attributed to early psychosocial and medical withdrawals.

International Society of Nephrology Global Kidney Health Atlas: structures, organization, and services for the management of kidney failure in Oceania and South East Asia

Oceania and South East Asia (OSEA) is a socioeconomically, culturally, and ethnically diverse region facing a rising epidemic of noncommunicable diseases, including chronic kidney disease (CKD). The second iteration of the International Society of Nephrology Global Kidney Health Atlas aimed to provide a comprehensive evaluation of kidney care in OSEA. Of the 30 countries/territories in OSEA, 15 participated in the survey, representing 98.5% of the region's population. The median prevalence of treated kidney failure in OSEA was 1352 per million population (interquartile range, 966-1673 per million population), higher than the global median of 787 per million population. Although the general availability, access, and quality of kidney replacement therapy (i.e., dialysis and transplantation) was high in OSEA, inequalities in accessibility and affordability of kidney replacement therapy across the region resulted in variability between countries. According to the survey results, in a third of the participating countries (mostly lower-income countries), less than half the patients with kidney failure were able to access dialysis, whereas it was readily available to all with minimal out-of-pocket costs in high-income countries; similar variability in access to transplantation was also recorded. Limitations in workforce and resources vary across the region and were disproportionately worse in lower-income countries. There was little advocacy for kidney disease, moderate use of registries, restricted CKD detection programs, and limited availability of routine CKD testing in some high-risk groups across the region. International collaborations, as seen in OSEA, are important initiatives to help close the gaps in CKD care provision across the region and should continue receiving support from the global nephrology community.

Aetiology, practice patterns and burden of end-stage kidney disease in South Asia and South-East Asia: A questionnaire-based survey

AIM

There is paucity of data on the epidemiology of end-stage kidney disease (ESKD) from South Asia and South-East Asia. The objective of this study was to assess the aetiology, practice patterns and disease burden and growth of ESKD in the region comparing the economies.

METHODS

The national nephrology societies of the region; responded to the questionnaire; based on latest registries, acceptable community-based studies and society perceptions. The countries in the region were classified into Group 1 (High|higher-middle-income) and Group 2 (lower|lowermiddle income). Student t-test, Mann-Whitney U test and Fisher's exact test were used for comparison.

RESULTS

Fifteen countries provided the data. The average incidence of ESKD was estimated at 226.7 per million population (pmp), (Group 1 vs. Group 2, 305.8 vs. 167.8 pmp) and average prevalence at 940.8 pmp (Group 1 vs. Group 2, 1306 vs. 321 pmp). Group 1 countries had a higher incidence and prevalence of ESKD. Diabetes, hypertension and chronic glomerulonephritis were most common causes. The mean age in Group 2 was lower by a decade (Group 1 vs. Group 2-59.45 vs 47.7 years).

CONCLUSION

Haemodialysis was the most common kidney replacement therapy in both groups and conservative management of ESKD was the second commonest available treatment option within Group 2. The disease burden was expected to grow >20% in 50% of Group 1 countries and 78% of Group 2 countries along with the parallel growth in haemodialysis and peritoneal dialysis.

Present status of renal replacement therapy in Asian countries as of 2017: Vietnam, Myanmar, and Cambodia

Since 2015, the Committee of International Communication on Academic Research of the Japanese Society for Dialysis Therapy has held its Asian symposium during the society’s Annual Congress to discuss the present status of and demand for dialysis therapy in Asian countries. The aim of the symposium is to identify needs and find ways to contribute in the area of dialysis therapy in these countries. Three manuscripts are presented here by participants at the 2017 Asian symposium from Vietnam, Myanmar, and Cambodia.

With economic development, hemodialysis (HD) therapy is now available worldwide. However, the cost of HD is very high compared with the average income in these three countries and, as of 2017, Cambodia and Myanmar have not yet established national health insurance systems. In Cambodia, patients must bear 100% of the cost for dialysis. In Myanmar, the government covers the cost of HD (20 USD, 40% of total cost) in public HD centers, but this service is still insufficient to meet current demand, with long waiting lists of up to 6 months at government HD centers. In contrast, in Vietnam, dialysis is almost completely covered by national health insurance. Dialyzers tend to be reused in all three countries. Continuous ambulatory peritoneal dialysis is available in Vietnam and Myanmar but not in Cambodia. Viable health insurance systems should be established as soon as possible in Cambodia and Myanmar, although this will ultimately depend on the countries’ level of economic development.

Experience of the first 6 years of pediatric kidney transplantation in Indonesia: A multicenter retrospective study

BACKGROUND

Pediatric kidney transplantation was only introduced in Indonesia in 2013. We therefore aimed to assess the characteristics and outcomes of transplants performed from its inception to January 2019.

METHOD

The study had a dual-center retrospective design. We examined the records of kidney transplant recipients and then calculated patient and graft survival rates by Kaplan-Meier survival analysis with 95% confidence intervals (95% CI).

RESULTS

In total, 12 kidney transplantations were performed in eleven children during the study period; among these, ten were boys, and nine had renal failure caused by congenital anomaly of the kidney or urinary tract. All donors were living, and all recipients were on dialysis at the time of transplantation, when their median age was 14.5 years (range, 8-19 years). Three patients died of infection in the first year of follow-up and two lost their allograft by the time of their last follow-up (median, 13 months; range, 4-69 months). The 1-year patient survival rate was therefore 68.18% (95% CI, 29.72%-88.61%), which remained unchanged at 3 and 5 years. However, the non-death-censored graft survival rates at 1, 3, and 5 years were 68.18% (95% CI, 29.72%-88.61%), 51.14% (95% CI, 14.5%-79.46%), and 25.57% (95% CI, 1.38%-64.78%), respectively.

CONCLUSION

Patient and graft survival rates after pediatric kidney transplantation in Indonesia are lower than those reported in other countries. Closer patient follow-up and stricter adherence to guidelines could improve transplant outcomes, but we must seek to improve the balance between infection and rejection.

Kidney failure in Samoa

BACKGROUND

There is limited literature on kidney disease in the Pacific Region, despite it being recognised as a leading cause of death in some Pacific Island nations. Kidney replacement therapy is only available in a handful of Pacific Islands. This paper reports the epidemiology of haemodialysis patients in Samoa.

METHODS

Registry data from the National Kidney Foundation of Samoa was analysed to estimate the incidence and prevalence rates of kidney failure from the rates of haemodialysis in Samoa and to explore some of the demographic features related to kidney failure in Samoa.

FINDINGS

In total, 393 patients have received long-term haemodialysis in the National Kidney Foundation of Samoa since its inception in 2005 until August 2019. 43% of the haemodialysis population were women and the mean age of people dialysed was 54.9 years. The crude mean incidence rate of kidney failure in Samoa, based on treated kidney failure cases, is 224 patients per million population with a crude prevalence of 629 patients per million population. Diabetic nephropathy (69.4%) was the leading cause of kidney failure.

INTERPRETATION

This is the first paper to report the epidemiology of haemodialysis patients in Samoa and reveals an urgent need for further studies on the extent of chronic kidney disease, and kidney failure, in Samoa to develop country specific prevention strategies to mitigate this growing burden and optimise care for kidney failure patients in Samoa.
