To address the unmet needs in the face of a growing demand for end-stage renal failure management and kidney transplantation in Asia, we have conducted a critical analysis of published literature and national registries to evaluate clinical outcomes and the rates of organ donation in Southeast Asia and the challenges facing these regions with regards to regulation, choice of donor source, and funding. Based on the available data, suggestions are proposed for an advancement of rates of organ donation and access, with emphasis on improved regulation and public education.
Organ transplantation (tx) is the treatment of choice for patients who suffer from end organ failure (1–3). With the increasing morbidity of organ failure due to the evolution of dietary and environmental triggers, there is increasing pressure on the tx wait-lists that do not match the growth in available transplants. Improved health care accessibility and longevity also result in a growing population of individuals with end-stage renal disease (ESRD) (4, 5). Global tx activity in 2014 rose by 1.81% from 2013, which only meet ~ 10% of the global need for new organs (6). Asia is the most populated region in the world but, conversely, has the lowest rate of organ tx and the greatest growth rate for numbers of people entering chronic and end-stage organ failure (6). In 2014, in Southeast Asia, the rate of organ tx was 3.8 patients per million population (ppmp), compared to 31.6 ppmp in the US and 27.9 ppmp in Europe (6). This discrepancy in morbidity and organ availability and vast social, economic, and political diversity in the region has fostered organ trafficking in Southeast Asia (7). The inequities in health care accessibility are further complicated in this region by epidemiological pressures (8), policies on health care financing (9), and medical technology diffusion (10). To update the impact of these changes on tx provisions in Southeast Asia, we reviewed the tx rate, the burden of organ shortage, organ access, legislation framework, reimbursement, and clinical outcome data in this continent. We also examined the causes of the unmet needs for organ tx in this region, compared to similar data from the US as an international benchmark, with a view to understanding regional pressures that can help to improve access and outcomes of organ transplantation in this region.
We searched the PUBMED electronic database for English-language peer-reviewed reports, computerized databases, government reports, dissertations, and online national registries in each of the countries in Southeast Asia. Relevant articles between 1956 and 2016 were reviewed for additional information as the databases and registries may not provide complete data due to the voluntary nature of their reporting.
The Southeast Asian continent has several strata of countries with wide variations in the gross national income per capita statistics from the World Bank (11) and human development index (HDI) from United Nations Development Program (12, 13). HDI is a composite index of the achievement in longevity, education, and income, which are three key dimensions of human development (13–15). There is evidence for an association of organ tx access with national income and HDI (10). Thus, we also provide income and HDI at a glance before exploring tx services in different countries in this region.
The Southeast Asian region has been defined following the division of geographic areas as assessed by the United Nations Statistic Division revised September 26th, 2016 (16). Southeast Asia consists of 11 members (Figure 1) ranked from high-income economies like Singapore and Brunei Darussalam to low-income economies like Cambodia, Laos, Myanmar, and Timor-Leste. Singapore is in the very high HDI while Myanmar is in the lowest. The trend of increased incidence of treated ESRD in developing countries is marked in this region (Figure 2). From the 2015 United States Renal Data System Annual data report, the greatest proportional increases in the incidence of treated ESRD over the interval from 2000/1 to 2012/13 were seen in the following countries (8): Thailand (1,210%), Philippines (185%), and Malaysia (176%). The reasons are because of improved standards of clinical care (17, 18), increased access to medical treatment (9), and longer life expectancy (19).

Organ Access, Legislation, and Reimbursement
Singapore is fully equipped for serving transplantation needs for its residents. It has a very high HDI and also has the highest incidence of treated ESRD (Figure 2). Though Singapore was not listed above for the largest proportional increase in treated ESRD in the region, as it has already reached a high level of >300 ppmp-treated ESRD in the year 2013, which is close to the figure of 363.1 ppmp-treated ESRD in the US (8). The rate of kidney tx reached a peak at 24.1 ppmp in 2006, but has stayed stable (Figure 2), due to a limitation in the rate of deceased donation. Despite the revision of the organ donation law in 2009, the deceased donation rate runs between 3 and 6 ppmp in Singapore (Table 1; Figure 3), versus a comparison of 25–26 ppmp in the US (Figure 3). Thus, the tx waiting list numbers of patients in Singapore continues to rise.

Singapore is the only country in Asia enabling presumed consent under The Human Organ Transplant Act (HOTA), enacted in 1987 (20–22). This act allows for the kidneys of all non-Muslim Singapore citizens and permanent residents between the ages of 21–60 without mental disorders, to be donated in the event of accidental death for tx unless they explicitly opt out. HOTA increased the deceased donor kidney tx rate from an average of 4.7 per annum (approximately 2 ppmp per annum) between 1970 and 1987 to an average of 40.8 per annum (approximately 11.4 ppmp per annum) between 1988 and 2004 (23). To expand the eligible donor pool, HOTA was amended in January 2004 to also allow transplantation of liver, heart, and cornea (24, 25). This bill extended organ donation from donors with non-accidental causes of death and added the regulation for organ donation from living (both related and unrelated) organ donors. It was later amended in August 2008 to include Muslim organ donors, and then in March 2009 to remove the upper age limit for potential deceased donors, paired kidney exchange permission, increased penalties for organ trading, and donor compensation (21, 22). Before the availability of HOTA, the Singapore government utilized the Medical Therapy, Education, and Research Act, which was the opt-in donation law enacted in 1973 (20–22). This law allowed any person to donate organs in the event of death for the purpose of treatment, education, or research (20–22). The Singapore government has also provided the criteria for determining death by brain death or cardiac death under The Interpretation Act (Certification and Determination of Death) (24).
Singapore established the National Organ Transplant Unit in 1970. This body regulates the national organ waiting list and maintains the national registry of recipients and donors (26). To date, kidney, liver, lungs, heart, corneas, skin, bone, and bone marrow tx are available in both public and private hospitals. Living donor tx are performed in both the public and private hospitals while deceased donor tx are carried out only in the public hospitals (27). Singaporeans receiving overseas tx return to follow-up in Singapore and are registered in national renal registry database if they have a functioning tx after 30 days (27).
Singapore has an excellent health financing system, where the public and the private sector work in cooperation for affordable health care (28) that utilizes 4.9% of GDP (Table 2), three times lower than the US, which uses 17.1% of the GDP for health care (15). Singaporean employees contribute to individual medical saving accounts, the Medisave program, which is a national healthcare savings scheme to afford payment for personal and family hospitalization costs. The Ministry of Health subsidizes lower- and middle-income patients for dialysis costs as well as selected immunosuppressive drugs in public healthcare institutions (29). Those patients also use the Medisave benefits to pay for their dialysis or immunosuppressive drugs after the government subsidies (28–30). To protect the poor, low-income patients have a right to apply for and get additional subsidies from the government, and welfare or charity organizations (29), such as the National Kidney Foundation, the Kidney Dialysis Foundation, and the Khoo Foundation.

The unadjusted 1- and 5-year kidney graft survival for living donor are excellent at 98.1 and 95.3%, as reported by the Singapore Renal Registry, compared to 95.1 and 80.2% from the US, as reported by Organ Procurement and Transplantation Network (OPTN) (31, 32). Selection bias and lower patients’ comorbidities are likely causes to support these excellent results. Outcomes for non-heart-beating donor kidney tx outcome are similar to heart-beating donors for the incidence of delayed graft function (50 versus 41%) or 2-year kidney graft survival (96 versus 98%) (33). Paired kidney donation can be undertaken after the last HOTA amendment in 2009 (34). The first case was enrolled in the Paired Exchange Registry in 2014 and operated in early 2015 (34). This program was expected to drive the tx rate, but Singapore’s relatively small population is an obstacle to finding compatible donor–recipient pairs. Hepatitis B virus (HBV)-infected, human immunodeficiency virus-infected patients, and alcoholic patients are excluded from tx in Singapore (26).
Brunei Darussalam is an Islamic state that has a high HDI similar to Singapore (13). Bruneians enjoy support from their government, and only 6% of health expenditure comes from personal contributions (15).
Organ Access, Legislation, and Reimbursement
Dialysis started in Brunei in 1967 and had progressively increased to more than 500 active cases at present (35). Organ tx became available within the country in 2013, with access only to living-related kidney tx. Prior to 2013, eligible ESRD patients were screened and matched with available living-related donors and sent overseas for tx, under government support (35, 36). Despite these efforts, problems exist with transplant tourism. The country has no official cell, tissue, and organ tx law (36), and tx growth in this region is limited due to poor public awareness, cultural concepts about brain death, and poor local transplant facilities (36). Nevertheless, the Brunei government is taking steps to improve access to health and tx care by increasing subsidies for health-care services (37, 38), and the establishment of 15 national health centers (39). It expands access to primary care, with 1.4 physicians per 1,000 people (15) and one nephrologist per 136-treated ESRD patients (38). The first Brunei Dialysis and Transplant Registry was initiated in 2011 (35, 38) and shows the high incidence (265 ppmp) and prevalence (1,289 ppmp) rates of ESRD with the predominant cause of ESRD being due to diabetes (35, 40).
There have been 49 cases of kidney tx from 1993 to 2012 (36). All of them were performed in foreign centers because the local tx activity only began in 2013. The 5- and 10-year overall graft survival rates are 91.1 and 81.2% (Table 3) with a 10-year patient survival rate of 90%, better than similar reports from Malaysia (41) and the OPTN (42), likely because this cohort of tx Bruneian patients is mostly younger, non-diabetic patients.
Malaysia is a multicultural and multi-faith country, consisting of Muslims, Buddhists, Christians, and Hindus, with Malay, Chinese, and Indian ethnicity (43). It has pursued economic growth and reached upper middle income (44). Malaysia has a high HDI, above the average Southeastern Asia HDI (13) and it spends 4.2% of its GDP in health expenditure (15).
Organ Access, Legislation, and Reimbursement
Renal replacement therapy was introduced in Malaysia in 1976 (45). Malaysia has an active dialysis program, with about 758 dialysis centers, most (94%) offering hemodialysis (46). Due to increased acceptance of dialysis as a mainstay therapy for ESRD in Malaysia, the prevalence of dialysis increased from 13,000 in 2005 to 35,000 in 2014 (46) (Figure 2). Malaysia is a welfare-oriented state (47). The Malaysian government is the principal payer of renal replacement therapy by a public–private partnership model (48, 49), and the government subsidizes both public dialysis centers and non-governmental organizations (48) such as the National Kidney Foundation. The Private Healthcare Facilities and Services Act, enacted in 2006, allowed hemodialysis facilities to be set up outside hospitals areas, which resulted in the rapid growth of private dialysis units and increased hemodialysis access (46, 48, 49). Tx was initially performed in Malaysia in the 1970s (45). Malaysia provides kidney, liver, and lung tx mostly in public medical centers under the National Organ, Tissue, and Cell Transplantation Policy, which was enacted in 2007 (50, 51). Organ tx programs are overseen by the National Transplant Council (51). The National Transplant Procurement Management Unit helps with deceased donor allocation and is supported by the local Tissue Organ Procurement Team in each donor hospital (51). Brain death diagnosis and certification is done under guidance from the Brain Death Committee (52). The National Transplant Waiting list is managed by The National Transplantation Unit, which was established within the Ministry of Health for regulating financial support and monitoring ethical standards for tx (51, 53). Between 2005 and 2014, the kidney tx rates fell by 50%, from 6 to 3 ppmp (46) due to a reduction in tx tourism, mainly in China (47) due in significant part to increased local legislation and the Istanbul Declaration (54), which desist organ trafficking. Living donation has to be authorized by the Unrelated Transplant Approval Committee (51) to limit transplant tourism.
According to the 2014 Malaysian Dialysis and Transplant Registry, the overall renal graft survival rates are 93, 88, 83, and 67% in year 1, 3, 5, and 10, respectively (Table 3) (46). The primary immunosuppressive regimen used are based on calcineurin inhibitor-based therapy with a decreasing use of cyclosporine (59% in 2010 to 44% in 2014) and increasing use of tacrolimus (32% in 2010 to 45% in 2014). Mycophenolic acid is used for 68% of kidney tx as maintenance therapy (55).
Thailand has a lower HDI than the previous regions and spends 6.5% of its GDP on health care (15). 7.9% of Thai health expenditure comes from personal contributions (15). Physician coverage in Thailand is sparse with 0.4 physicians per thousand people (15), much lower than Malaysia (1.2 physicians per thousand people) or Singapore (2 physicians per thousand people), even though the incidence of treated ESRD is equivalent (Figure 2).
Organ Access, Legislation, and Reimbursement
The growing incidence and prevalence of ESRD (157.8% increase from 2007 to 2009), with stable numbers of kidney tx in the region (9), has contributed to an expanding kidney tx waiting list in Thailand. The Universal Coverage Scheme (UCS) authorized by the National Health Security Act enacted in 2002 (56–58), supplemented health-care support (56–59) with expanded coverage for renal replacement therapy through the Thai peritoneal dialysis (PD) first policy (2007) and kidney tx (9) (Table 2). To date, all Thais can get access to dialysis and tx through one of three major health schemes in the country, the largest being through UCS (9, 60).
The first kidney tx was done in Thailand in 1972 (61, 62). Thailand now provides bone marrow, liver, heart, lung, and heart and lung transplantations in 26 transplant centers around the country (63). Brain death criteria were set up in 1989 and revised in 2011 (64). The Organ Donation Center is a non-for-profit, central organization, established in 1994 under the umbrella of the Thai Red Cross Society (64, 65), responsible for national waiting lists, centralized deceased donor allocation, accreditation of tx centers, with voluntary data reporting from tx centers (64). Public organ donation campaigns have been supported by the Thai Royal family to increase awareness, organ access, and extended coverage for kidney tx (65, 66). Moreover, the Organ Donation Center with collaboration from the Ministry of Public Health have established full-time transplant coordinator teams in 24 referral hospitals to help with organ recovery and procurement (67). As a result, the kidney tx rate is increasing (Figures 1 and 2).
The renal graft survival and patient survival rates are comparable to other registries and have improved significantly over the last two decades (63). One-, 5-, and 10-year death-censored renal graft survival rates are 95.4, 89.3, and 83.7% for living donor tx versus 96.2, 90.0, and 78.9% for deceased donor tx (63). The most commonly used immunosuppressive regimen comprises of tacrolimus, mycophenolate, and prednisolone that is similar to the US. Induction therapy is used for 70.4%; interleukin-2 receptor antagonist is the most common induction agent while T-cell-depleting agents are more common in the US (68). Induction therapy is being increasingly used, with 55% use in 2012 to 70.4% in 2015 (63, 68, 69). Pediatric kidney tx outcomes reported 1-year patient and graft survival rates of 100% either for living donor or deceased donor tx, with similar immunosuppressive regimens as in adults. One-, 5-, and 10-year graft survival rates are 96.2, 81.9, and 64.4%, respectively (68). Thailand offers kidney tx for HBV- and HCV-positive patients, as well as ABO-incompatible kidney tx in some centers (70). Donation after cardiac death and paired kidney exchange program is not available to date.
The Philippines spends 4.7% of GDP for health expenditure, but unlike the former countries that have more government support (Table 2), Filipinos personally pay for about 53.7% of their health expenses (15).
Organ Access, Legislation, and Reimbursement
The Philippines have growing rates of ESRD (Figure 2), with expanding wait lists as organ donation rates are stagnant with deceased donation rate as low as 1 ppmp (Table 1) (71). The flat rate is on the grounds of high out-of-pocket in health-care costs for dialysis and living kidney tx (72), and a shortage of the necessary infrastructure support to enhance organ donation, procurement, allocation, and tx (73). The Philippine Health Insurance Corporation (PhilHealth) was implemented in 1995, but partial coverage for dialysis was only included in an amendment in 2006 (74, 75). In 2012, PhilHealth provided the Z Benefits Package covering catastrophic illnesses like malignancies and kidney tx, and in 2015, it expanded coverage for hemodialysis sessions from 45 to 90 sessions per year, and for PD from 270 to 360 days per year (76). The Philippines performs kidney, liver, pancreas, bone marrow, and islet cell as well as double transplants like liver and kidney or pancreas and kidney (77, 78). The Philippine Network for Organ Sharing (PHILNOS), established by the Department of Health in 2010, is the central coordinating body of all deceased organ or tissue donation and tx activities (79, 80) and governs various operational guidelines including the brain death protocol, allocation scoring, deceased donor referral, waiting lists. The PHILNOS is monitored by the External Audit Department with particular emphasis on organ allocation procedures. The PHILNOS runs the Philippines Organ Donor and Recipient Registry System, and the deceased allocation system is centralized under the Donor Allocation Scoring System (81). The National Transplant Advisory Board, National Transplant Ethics Committee, and the Kidney Donor Monitoring Unit, all help set tx guidelines (82).
Kidney tx in the Philippines is mostly from living donors (94%) (Table 1), from both living-related and unrelated donors; with the larger proportion (70.1%) being from unrelated donors (83). For related donors, non-immediate family members are also eligible donors (73). Donor compensation as “gratitudinal gifts” to living unrelated donor is allowed (82). Before 2008, the government approved a 10% cap to each tx center to allocate living donors from Filipinos to foreigners, in situations when Filipinos recipients were not available (82, 84–86). Unfortunately, this resulted in unacceptable rates of organ trafficking such that, in 2008, in an effort to eliminate tx tourism, the PHILNOS prohibited all tx to foreigners using Filipino organs. The World Health Organization identified the Philippines, China, and Pakistan as key areas driving organ trafficking (80). With support from the 2008 Declaration of Istanbul on Organ Trafficking and Transplant Tourism, the Philippines government enacted the anti-commercialization of human organs, tissues, or part of living persons Act of 2008 (86, 87). This Act established the Philippines Board for Organ Donation and Transplantation to oversee policy implementation and to define penalties by imprisonment and fines.
The majority of kidney tx patients in the Philippines are prescribed tacrolimus, mycophenolate, and prednisone for initial immunosuppression. As most of them are living donor recipients, 99% of recipients received induction therapy with either Basiliximab or rabbit anti-thymocyte globulin, and 98% have immediate graft function, with minimal or absent rates of delayed graft function in most centers (88). Nevertheless, the report of graft and patient survival rates from the Philippines are difficult to access.
Indonesia is the most populous Muslim-majority in the world with the largest economy in Southeast Asia (89). Though the government had expanded universal coverage for nearly half of population in 2014, Indonesians still pay out-of-pocket for 46.9% of health expenditure (Table 2) (15, 90). The little government spending in social health security increases the health-care cost burden on patients and families (91). This impact is most on the poor, who can have limited access to dialysis and tx care.
Organ Access, Legislation, and Reimbursement
Hemodialysis was introduced in Indonesia in 1967 and PD in 1985, but both have progressed slowly due to limited reimbursement (92, 93). After the government initiated health-care reform with dialysis coverage in 2005, the number of treated ESRD has grown rapidly to ~200 ppmp by 2013 (8). However, detailed data on the actual gap between patients needing dialysis and those receiving kidney transplants in the region are lacking (48), and it seems that up to one-third of ESRD treatment may be self-funded (30).
The first kidney tx in Indonesia was recorded in 1977 (94). The Indonesia 1991 Health Regulation provided for the procurement of tissue from living donors, but not from deceased donors (95). The Kemayoran Consensus was signed in 1995, which stated that all religions in Indonesia accepted the concept of organ tx, and human organ commercialization is forbidden (94). In support of this, the Indonesia Islamic Groups and the Federation of the Islamic Medical Association have endorsed the concepts of brain death (52). In 2014 (89–91, 96), the government launched Indonesia’ universal health coverage/jaminan kesehatan nasional (UHC/JKN) to cover 120 million people who are already engaged in various social health insurance schemes into the Social Security Management Agency for the Health Sector (89). The UHC/JKN program has a target to enroll 250 million people by 2019.
For those included in this program, all costs for hemodialysis and PD with three continuous ambulatory PD fluid exchanges are covered by government health insurance (93). Costs for kidney tx are also covered partly by government health insurance (97), though to date, only 7 from 33 medical centers in the country participate for full JKN coverage (90). There are concerns that the growth of JKN may be halted by regulation disparities, poor health-care infrastructure, and the urban–rural gap in the number of medical staff (90).
In 2009, three centers in Indonesia performed kidney tx. Kidney tx from “emotionally-related” donors and the spouse, is accepted in Indonesia (94). Five- and 15-year renal graft survival rates are 60 and 50% (94). Immunosuppressive drug combinations consist of either cyclosporine A, azathioprine, and corticosteroids or tacrolimus, mycophenolate mofetil, and corticosteroids (97).
Vietnam has enjoyed rapid economic growth with a dramatic reduction in poverty over the last decade (98). Social and health-care outcomes have improved significantly (98). In 2014, the Vietnamese government spent 7.1% of its GDP on health care and Vietnamese personally pay for ~36.8% of health-care expenditure (Table 2) (15).
Organ Access, Legislation, and Reimbursement
Major economic reforms have been introduced in Vietnam including the introduction of social health insurance and permission for private sectors in health care. Dialysis was included in insurance coverage with erythropoietin therapy in 2005, and ~50% of tx therapy is covered (99–101). Increasing numbers of patients receive hemodialysis and PD in Vietnam, and it is estimated that the prevalence of treated ESRD is more than 120 ppmp (100). The first kidney tx was performed successfully in Vietnam in 1992 (99), and currently, Vietnam also performs liver and heart transplants. Before 2006, only living-related organ tx were allowed. The Vietnamese government passed a law in 2006 for regulation of living and deceased organ donation, the organization of tissue banks, the establishment of the National Coordination Center for Human Organ Transplantation, and decreeing prohibiting of organ commercialization (99, 102). The law provided living donor compensation such as free health insurance cards, free regular health check, and to get prioritized tx themselves. It also addressed brain death criteria, diagnostic protocols, and the establishment of tx centers. Living donors had to have the same bloodline with the recipient or were required to be the next of kin within three generations of the recipient. The law also allowed Vietnamese in going abroad for donating organs to their relatives or vice versa (102). Unrelated living donors, namely, husbands or wives or friends were acceptable donors.
The National Coordination Center for Human Organ Transplantation is responsible for organizing donated body tissue and organs and will cooperate with tissue banks and hospitals nationwide. To date, ~400 living donor kidney and liver txs and ~10 deceased donor txs have been done in Vietnam. Thirteen health-care facilities meet the regulations and conditions for carrying out body tissue and organ txs in Vietnam (103). The deceased donor organ tx program still faces impediments and suggested improvements to the system are to set up a national online database system and increased public education on deceased donor donation.
Single center data show that 1- and 3-year renal graft survival is 82 and 65% from living donors, with 1- and 3-year patient survival at 82 and 73%, respectively (Table 3) (104). Immunosuppression usage consists of anti-interleukin-2 receptor monoclonal antibody induction and triple drug regimen as maintenance therapy with cyclosporine or tacrolimus, mycophenolate mofetil or mycophenolic acid sodium, and corticosteroids.
Organ Access, Legislation, and Reimbursement
There is the lack of government health-care payment for chronic disease care like dialysis or tx in Myanmar (105). Burmese patients support high out-of-pocket costs to the tune of 50% of their health-care expenditures (Table 2) (15). Recently, a trial prepaid health insurance system was started in July 2015 with cooperation from national and international non-governmental organizations (106).
The first kidney tx in Burma was done in 1997 (107). Only two hospitals in Myanmar perform kidney txs—Yangon General Hospital and Mingalardon Military Hospital (108). Due to a lack of sufficient infrastructure to support tx needs for all patients with ESRD in Myanmar, many private-pay-patients get their tx in India (109). The government promulgated the Body Organ Donation Law in 2004, which allows deceased organ donation and living-related organ donation within immediate family members (108, 110). This law sets heavy penalties for organ commercialization by imprisonment for up to 3 years.
There are limited sources of information to find out the number and clinical outcome of tx activities in Myanmar. However, there is a single-center report of 21 living-related donor kidney tx with 95% 1-year- and 91% 6-year-graft survival rates (Table 3) (107).
Laos, Cambodia, and Timor-Leste
Cambodia has at least 10 hemodialysis units available for ~200 patients, but patients have to cover 100% of costs as there is no government subsidy (111). To date, there are no significant tx activities in Laos, Cambodia, and Timor-Leste, and patients have to go overseas for tx.
There is a growing demand for organ tx in Southeast Asia, which is currently not being met due to various reasons that range from access, infrastructure, economics, and legislation. The unmet need is evident, but ESRD disease epidemiology and prevalence can be difficult to assess in some countries in Southeast Asia due to a lack of standardized national registry data. Improved access to tx will also require increased procedure affordability by transitioning health-care financing away from the patient and toward national coverage (9). The WHO Madrid consultation (10, 112) in 2010 proposed a 1–5 tier system (with 5 being the highest) for ranking the capabilities of regional tx services. Three of the 11 Southeast Asian countries are at level 1 (Laos, Cambodia, and Timor-Leste). Thailand and Singapore were reported to have level 4 services, Malaysia, the Philippines, and Vietnam have level three services, and Indonesia and Myanmar showed having level 2.
Suggested Strategies for Increasing Tx in Southeast Asia
A review of the regions above suggests that improved access and outcomes for ESRD and tx will require attention to the following prime factors.
Developing a Framework to Increase Deceased Donation
There are two deceased donor structures in the Southeast Asia, i.e., the opting-in system based on informed consent, and the opting-out system based on presumed consent. Singapore is the only state in the region that has the opting-out scheme. Enrollment for the opting-in scheme is hampered in regions that have low rates of available physicians and trained coordinators, and high clinical services workload can lead to less time for communication. A priori consent at information repository centers such as driver licensing registration or tax-return registration can improve donor organ access.
Southeast Asia has a high incidence of deaths from fatalities involving stroke and road traffic accidents. In fact, Thailand ranks second in the world for traffic fatalities with a mortality rate of 36.2 patients per 100,000 population (113) and fatality from stroke is the most common cause of death in Thailand with more than 250,000 new cases and 50,000 lives claimed annually (114). Thus, there can be a high volume of eligible brain death donors. Legislation to support the diagnosis of brain death and optimal support from transplant coordinator teams is crucial to increase the deceased donation rate in this region. Another measure to expand the donor pool is to enable the use of non-heart-beating donors as outcomes for kidney grafts are comparable to transplants from brain dead donors in the US and Singapore (33, 115). Education of professionals with organ reperfusion skills to maintain these organs is also needed in the ICUs in these regions (115–117).
Increased Access to Living Donors
Increased rates of living donation can be accomplished by inclusion of unrelated donors, namely emotionally related donors, such as a spouse, friend, in-law, stepparent, adoptive children, friend, or even an altruistic stranger (118, 119). But concerns lie in this region that expanding the criteria for acceptable living donors can adversely impact organ commercialism (73, 84, 120). Southeast Asian countries allow living donation from a spouse included Malaysia, Thailand, Philippines, Indonesia, and Vietnam. In Myanmar, only immediate family members are authorized to donate.
Donor Compensation—The Sticky Wicket
Donor “compensation” is interpreted as donor “incentives” by some. The term “incentive” refers to all forms of material gain or similar advantage offered for consent to living donation or authorization of deceased donation of organs (121). The term “compensation” refers to payment for the costs incurred around tx that would cause the donor financial hardships and would include activities such as traveling and accommodation costs and lost wages (122–124). In the US, National Organ Transplant Act has allowed for financial compensation for the necessary expenses incurred by the donor of a human organ (125). In 2004, the Organ Donation and Recovery Improvement Act was launched to enable funding for an organ donation awareness program and public education as well as funding for donor compensation (126). The National Living Donor Assistance Center approves of grants to pay for travel and subsistence expense for some living donors who have financial hardship (125). In countries without universal health care, prospective donors might not have insurance to cover following complications or even to pay for a routine check-up. Often, potential donors are also concerned that donation might restrict their hiring opportunities (127). The Philippines program has allowed gifts based on gratitude, supporting compensation for health and life insurance, lost income, and education (82, 84). Regulated compensation can provide a rational, accessible, and equitable donor allocation program (82). Aside from financial compensation, non-financial support for the donor can come in the form of community recognition that is a valuable commodity in Asia. Saudi Arabia offers donors “the King Abdul Aziz medal” as well as a discount card with Saudi Airlines (128).
Management of the National Registry, Waiting Lists, and Central Allocation
Professional organizations such as the nephrology societies in each region should support national registries; the Singapore Renal Registry, the Malaysian National Renal Registry, and Thailand Renal Replacement Therapy Registry are three such registries in the area. A centralization of deceased organ allocation will ensure equity of allocation and get the best match.
Health Financing System
We think that health-care reform can help increase end-stage organ disease access to treatment and tx activities in this region. Aside from Medicare and Medicaid that enacted since 1965, Americans have abided by the Patient Protection and Affordable Care Act that passed in 2010 (129). The last law mandates that persons over the age of 18 obtain health insurance, either through their employer or public insurance program in case they cannot afford insurance otherwise. Having a reliable funding for health care is mandated to improve access to renal replacement therapies.
The tx workforce in Asia is very limited (130). Without strategic planning to improve the number of well-trained specialists, the delivery of care to patients with end-organ failure or tx will be threatened (130). Education of the population is also critical, especially in a region with many religious, cultural, and social traditions, which can create barriers to organ donation (131, 132). The drive for altruistic donation in the community requires continued public awareness and public education.
In conclusion, there is recognition of the growing burden of end-stage organ failure in Southeast Asia. The gap between the tx waiting lists and available organs for tx is expanding.
Improved legislation, health-care reform, and education are key drivers to improve donor availability. National registries are urgently needed in the entire region to review and improve tx access and outcomes. Continued heightened surveillance to support legal practices in organ harvesting and donation and strict laws to curb transplant commercialization and tourism are necessary to have in place and enforce. With these practices in place, the next decade will likely show rapid advances in access to state of the art medical management for renal failure and renal tx, with a significant impact on improving population mortality and morbidity in Southeast Asia.
