End-Stage Renal Disease and Its Treatment in Latin America in the Twenty-First Century

The Latin American Society of Nephrology and Arterial Hypertension's Dialysis and Transplant Registry was chartered in 1991. It collects information on ESRD and its treatment in 20 countries of the region. The prevalence of patients on renal replacement therapy (RRT) increased from 129 pmp in 1992 to 447 pmp in 2004; in 2004, 56% of the patients were on hemodialysis, 23% on peritoneal dialysis, and 21% had a functioning kidney graft. The highest rates of prevalence were reported in Puerto Rico (1027 pmp), Chile (686 pmp), and Uruguay (683 pmp). Hemodialysis was widely used, except in El Salvador, Mexico, Guatemala, Nicaragua, and the Dominican Republic, where peritoneal dialysis predominated. Incidence rate increased from 27.8 pmp to 147 pmp in the same period of observation; the lowest rate was reported in Guatemala (11.4 pmp) and the highest in Puerto Rico (337.4 pmp). Diabetes mellitus was the leading cause of renal failure in incident patients; the highest rates were reported in Puerto Rico (62.2%) and Mexico (60%). Forty-four percent of the incident population were older than 65 years. Access to renal replacement therapy was universal in Argentina, Brazil, Chile, Cuba, Puerto Rico, Uruguay, and Venezuela, while was restricted in other countries. Main causes of death in dialysis were cardiovascular (44%) and infectious disease (26%). The rate of renal transplantation increased from 3.7 pmp in 1987 to 14.5 in 2004; fifty-three percent of the organs came from cadavers. Overall, donation rate was 5.9 pmp. In conclusion, the prevalence and incidence rates have increased over the years, and diabetes mellitus has emerged as the leading cause of kidney disease in the region. Although the rate of kidney transplantation has increased, the number remains insufficient to match the growing demand. The implementation of renal health programs in the region is urgently needed.     

The Latin American Dialysis and Renal Transplantation Registry Annual Report 2002

Latin America is a conglomerate of adjacent countries having in common a Latin extraction and language (Spanish or Portuguese) and exhibiting extreme variations in socioeconomic status. The Latin American Society of Nephrology and Hypertension Dialysis and Renal Transplantation Registry was created in 1991. Annual data are sent by local societies in 3 forms: patient, center, and country. The prevalence of renal replacement therapy (RRT) (all modalities) increased from 119 patients per million population (pmp) in 1991 to 349 pmp in 2001; the acceptance rate was 91.7 pmp in 2001. Dialysis prevalence was 277 pmp; hemodialysis was the predominant modality, except in Mexico (86% on peritoneal dialysis). The highest dialysis prevalence and acceptance rates were reported by Puerto Rico, Uruguay, and Chile. Among incident patients, diabetic nephropathy (33%) and nephroangioesclerosis (32%) were the primary causes; 38% were older than 65 years old. Renal transplants increased from 3.7 pmp in 1987 to 13.7 pmp in 2001. In 2003, 6357 transplants were performed (55% living donor); the cumulative number performed since 1987 reached 55,947. Prevalence and incidence are low because not all patients with end-stage renal disease have access to RRT because of restricted availability, difficulties in referral, and inequities in coverage. The annual increase in the number of patients on RRT (8%-10%) is higher, proportionally, than the annual growth of the Latin American population in general (1.5%). Efforts must be focused on prevention and treatment of chronic kidney disease, especially in diabetic and older patients, and in implementing better organ donation programs to improve the pool of cadaveric donors.     

Organ donation in Latin America

Recently in Latin America, there has been a strong influence of the "Spanish model" of organ procurement. In 2001, The "Punta Cana Group" was created by Latin American transplantation coordinators with the objective of registering and improving the system of donation and procurement. In many countries there is no universal financial support from the government for medical treatment, including dialysis and transplantation. In other countries there is complete financial support for all of the population, including immunosuppressive drugs. Practically all countries have transplantation laws that follow ethical concepts, such as brain death diagnosis criteria, forms of consent, criteria of allocation, and inhibition of commerce. The rate of potential donors notified in countries that perform transplantations with deceased donors varied from 6 to 47 per million population yearly (pmp/y); The rate of effective donors varied from 1 to 20 pmp. In 2004, the mean rate of effective donors in Latin America was 5.4 pmp. The family refusal rate for the donation of organs varied from 28% in Uruguay to 70% in Peru. In some countries, such as Puerto Rico, Uruguay, and Cuba, it was more than 15 pmp, whereas in others countries deceased donors were practically not used. The number of patients on the waiting list for solid organ transplants in 12 Latin American countries is 55,000. Although the donation rate has increased by 100% during the last 10 years, it is lower than that in Europe (15 pmm/y) or the United States (20 pmp/y).     

Chronic kidney disease in Cuba: epidemiological studies, integral medical care, and strategies for prevention

The experience of the Republic of Cuba regarding epidemiological studies, integral medical care, and strategies for the prevention of chronic kidney disease is summarized in this report. Cuba has a National Program for Chronic Renal Disease, Dialysis, and Renal Transplantation. There is a national nephrology net, integrated by the Institute of Nephrology as the coordinator center, that has 47 nephrology services with a hemodialysis unit (24 of them with peritoneal dialysis unit), 9 transplantation centers, 33 organ procurement hospitals, and 5 histocompatibility laboratories.In 2004, the incidence rate in dialysis patients was 111 pmp, and the prevalence rate was 149 pmp, demonstrating an increasing mean of 17.0% and 10.0% per year, respectively. Renal transplantation rate was 16.6 pmp. The detection, registration, and follow-up of patients with chronic kidney disease (serum creatinine > or =1.5 mg/dL or glomerular filtration rate <60 mL/min) by family doctors was 9,761 patients, 0.87 patients per 1,000 inhabitants.In the 1980s, three population-based screening studies were performed to define the burden of chronic renal failure in different regions of Cuba. The prevalence rate was 1.1, 3.3, and 3.5 per 1,000 inhabitants, respectively. At present, another three population-based screening studies are ongoing in order to detect the chronic kidney disease in earliest stages.The continuing medical education activities have been very useful in raising the awareness of medical doctors and the basic health staff about the threats posed by and the strategies to prevent, diagnose, and treat chronic kidney disease.     

The health system in Chile: the nephrologist perspective

Chile is a country with 17 million inhabitants, 13% of them living in rural areas, and with a per capita income of approximately US $14,500. Three percent of national income is assigned to the health budget, with a mixed public and private system, with guaranteed medical benefits from the state to cover chronic kidney disease (CKD) and renal replacement therapy (RRT). Hemodialysis has reached in 2009 a prevalence of 857 patients per million population (pmp). Peritoneal dialysis is less developed, with a prevalence of 40 patients pmp. Both therapies show good quality indexes with a patient mortality rate close to 12% per year. A centralized national renal transplantation program registered 5,949 renal transplants performed up to 2009. Renal survival at 5 years is 86% for living and 76% for cadaveric donor transplants. Organ donation is relatively low with 7.1 cadaveric donors pmp in 2009, despite legal and educational strategies to increase it. Although the country demonstrates one of the highest standards for RRT indexes in Latin America, the proportion of resources invested makes it necessary to improve early diagnosis and renal prevention policies to avoid having the growing incidence of CKD constrain the national health budget.     

Renal replacement therapy in the Canary Islands: demographic and survival analysis

BACKGROUND: The continuous increase in the number of patients on renal replacement therapy (RRT) has heightened the importance of renal patient registries to respond to the demand for data on the state of health, quality and cost of care provided for these patients. Our aim was to analyze the epidemiological profile of this population in the Canary Islands. METHODS: All patients on RRT between January 1999 and December 2003 were considered in this analysis. The information was obtained from the database of the Canary Registry of Renal Patients. RESULTS: We observed a continuous increase in incidence throughout the study period (from 138 per million population (pmp) in 1999 to 160 pmp in 2003), being more evident in patients >65 yrs. Prevalence followed a similar course, increasing from 875 to 972 pmp, being especially evident in the 65-74 yr age group. An alarming finding was the high incidence (43.5%) and prevalence (37.5%) of diabetic nephropathy. While the proportion of hemodialysis (HD) or transplant patients increased, that of peritoneal dialysis (PD) remained low and stable (prevalence of 5% in 2003). Almost half the RRT patients had functioning grafts, with a notably high rate of 58 transplants pmp in 2003, and a prevalence of 425 pmp. Age (hazard ratio (HR) [95% confidence interval (95% CI)] 1.04 [1.03-1.05]; p < 0.001) and diabetic nephropathy (1.47 [1.19-1.82]; p < 0.001) were independently associated with mortality in dialysis patients. Those returning to dialysis after graft loss had a 69% greater risk of death than incident dialysis patients (1.69 [1.06-2.69]; p = 0.026). Cardiovascular events were the main cause of death in all dialysis modalities. Patient death was the main cause of graft loss. CONCLUSIONS: The most outstanding finding was the high incidence and prevalence of patients on RRT, mainly due to diabetic nephropathy. Renal transplant rates were among the highest reported in renal patient registries.     

Renal replacement therapy among disadvantaged populations in Mexico: a report from the Jalisco Dialysis and Transplant Registry (REDTJAL)

BACKGROUND: End-stage renal disease represents a serious public health problem in Jalisco, Mexico. It is reported among the 10 leading causes of death, with an annual mortality rate of 12 deaths per 100,000 population. The state population is 6.3 million, and more than half do not have medical insurance. In this study, we report the population's access to renal replacement therapy (RRT). METHODS: Patients > or =15 years of age, who started RRT between January 1998 and December 2000 at social security or health secretariat medical facilities, were included. Nine facilities participated in the study. At the start of treatment, the patient's facility, age, gender, cause of renal failure, and initial treatment modality were registered. RESULTS: Within the study period, 2456 started RRT, 1767 (72%) at social security facilities and 687 (28%) at health secretariat facilities, for an annual incidence rate of 195 per million population (pmp). The main cause of renal failure was diabetes mellitus (51% of patients). There were significant differences between the 2 populations. Patients with social security were older (53.1 +/- 17 vs. 45.1 +/- 20 years, P= 0.001) and had more diabetes (54% vs. 42%, P= 0.001) than those without social security. They had higher acceptance (327 pmp vs. 99 pmp, P= 0.001) and prevalence rates (939 pmp vs. 166 pmp, P= 0.001) than patients without medical insurance. Dialysis use was similar in both populations. Eighty-five percent of patients were on continuous ambulatory peritoneal dialysis and 15% on hemodialysis. Kidney transplant rate was higher among insured patients (72 pmp vs. 7.5 pmp, P= 0.001). The number of dialysis programs and nephrologists that offered renal care also differed. There were 10 dialysis programs in social security and 3 in health secretariat facilities. Fourteen nephrologists looked after the insured population, whereas 5 cared for the uninsured (7.7 pmp vs. 2.1 pmp, P= 0.001). The latter had access to 8 hemodialysis stations compared with 34 for the insured population (3.4 pmp vs. 18.8 pmp, P= 0.001). CONCLUSIONS: Access to RRT is unequal in our state. Although it is universal for the insured population, it is severely restricted for the poor. Social and economical factors, as well as the limited number of understaffed, centralized dialysis facilities, could explain these differences.     

Rapport REIN 2005 — Synthèse

In 2005, 6,021 patients with end-stage renal disease living in fourteen regions covering 45 millions inhabitants (73% of the French population), started renal replacement therapy (dialysis or preemptive graft): median age was 70 years; 3% had a preemptive graft. The overall crude annual incidence rate of renal replacement therapy for end-stage renal disease was 139 per million population (pmp) in thirteen regions that met exhaustivity, with significant differences in sex and age-adjusted incidence across regions (92 to 171 pmh). At initiation, 48% of the patients had at least one cardiovascular disease and 36% diabetes (89% Type 2 non-insulin-dependent diabetes).On December 31, 2005, 21,813 patients living in these fourteen regions were on dialysis: median age was 69 years. The overall crude prevalence rate of dialysis was 539 pmp in thirteen regions. On December 31, 2005, 19,491 patients were living with a functioning graft : median age was 53 years. The overall crude prevalence rate for these patients was 390 pmp in thirteen regions. The overall crude prevalence rate of renal replacement therapy for end-stage renal disease was 929 pmp in thirteen regions, with significant differences in age-adjusted prevalence across regions (732 to 1009 pmh).In the 2002-05 cohort of 11,632 incident patients, the overall one-year survival rate was 82%, 72% at 2 years and 62% at 3 years. Survival decreased with age, but remained above 50% at 2 years in patients older than 75 at RRT initiation.Among the 5,902 new patients starting dialysis in 2005 in the 14 regions, 7% had a BMI lower than 18,5 kg/m² and 16% a BMI higher than 30. At initiation, 63% had an haemoglobin value lower than 11g/l and 9% an albumin value lower than 25 g/l. The first haemodialysis was started in emergency in 30% of the patients and with a catheter in 46%.On December 31, 2005, 8% treated in the dialysis units of the fourteen regions received peritoneal dialysis, of which 35% were treated with automated peritoneal dialysis. 94% of the patients on haemodialysis had 3 sessions per week, with a median duration of 4 hours.In 2005, 1,911 patients received a renal graft. On December 31, 2005, 4,634 patients were on the waiting list for a renal graft in the transplantation centres of the 14 regions.

The 2008 ERA-EDTA Registry Annual Report-a précis

Background. This study provides a summary of the 2008 ERA-EDTA Registry Report (this report is available at www.era-edta-reg.org).Methods. The data on renal replacement therapy (RRT) were available from 55 national and regional registries in 30 countries in Europe and bordering the Mediterranean Sea. Datasets with individual patient data were received from 36 registries, whereas 19 registries contributed data in aggregated form. We presented incidence and prevalence of RRT, and transplant rates. Survival analysis was solely based on individual patient records.Results. In 2008, the overall incidence rate of RRT for end-stage renal disease (ESRD) among all registries reporting to the ERA-EDTA Registry was 122 per million population (pmp), and the prevalence was 644?pmp. Incidence rates varied from 264?pmp in Turkey to 15?pmp in Ukraine. The mean age of patients starting RRT in 2008 ranged from 69?years in Dutch-speaking Belgium to 44?years in Ukraine. The highest prevalence of RRT for ESRD was reported by Portugal (1408?pmp) and the lowest by Ukraine (89?pmp). The prevalence of haemodialysis on 31 December 2008 ranged from 66?pmp (Ukraine) to 875?pmp (Portugal) and the prevalence of peritoneal dialysis from 8?pmp (Montenegro) to 115?pmp (Denmark). In Norway, 70% of the patients on RRT on 31 December 2008 were living with a functioning graft (572?pmp). In 2008, the number of transplants performed pmp was highest in Spain (Catalonia) (64?pmp), whereas the highest transplant rates with living-donor kidneys were reported from the Netherlands (25?pmp) and Norway (21?pmp). In the cohort 1999-2003, the unadjusted 1-, 2- and 5-year survival of patients on RRT was 80.8% (95% CI: 80.6-81.0), 69.1% (95% CI: 68.9-69.3) and 46.1% (95% CI: 45.9-46.3), respectively.     

Latin American registry of dialysis and renal transplantation: 1993 annual dialysis data report

Background: The Latin America Registry of Dialysis and Transplantation was created in October 1991 and comprises the national Societies of Nephrology from 21 countries with a total population of 468.56 million inhabitants. Methods: This report includes data from 21 181 patients from Argentina, Brazil, Chile, El Salvador, Panama, Paraguay, Peru, Puerto Rico, Uruguay, and Venezuela who were receiving chronic dialysis treatment during 1993. Data was collected by individual patient questionnaire except from Chile and Brazil where the data was obtained from a local centre questionnaire. Results: The prevalence rate averaged 131.1 per million population. The mean age of the 8972 incident patients was 50.5 years, with 58.2% males. The more frequent causes of renal failure were glomerulopathies (22.6%), vascular nephropathy (20.9%) and diabetes (16.9%). Haemodialysis was the most used treatment (88.3%). Gross mortality was 21.1% and the more frequent causes of death were cardiac complications and infections. The analysis of mortality risk factors using a logistic regression model showed that diabetics patients older than 65 years had the highest probability of death (43.0%) and patients with glomerulonephritis, younger than 65 years had the lowest (8.0%). The adjusted mortality rate was 241 deaths/1000 patient-years at risk when the USRDS 1987-1989 white mortality rate by age groups and primary diseases was used as standard. Conclusion: In spite of the economic difficulties, very important efforts have been made to treat ESRD patients and gross mortality statistics in some countries are similar to those reported by other regional registries.     

Chronic Kidney Disease in Cuba: Epidemiological Studies,Integral Medical Care,and Strategies for Prevention

The experience of the Republic of Cuba regarding epidemiological studies, integral medical care, and strategies for the prevention of chronic kidney disease is summarized in this report. Cuba has a National Program for Chronic Renal Disease, Dialysis, and Renal Transplantation. There is a national nephrology net, integrated by the Institute of Nephrology as the coordinator center, that has 47 nephrology services with a hemodialysis unit (24 of them with peritoneal dialysis unit), 9 transplantation centers, 33 organ procurement hospitals, and 5 histocompatibility laboratories.

In 2004, the incidence rate in dialysis patients was 111 pmp, and the prevalence rate was 149 pmp, demonstrating an increasing mean of 17.0% and 10.0% per year, respectively. Renal transplantation rate was 16.6 pmp. The detection, registration, and follow-up of patients with chronic kidney disease (serum creatinine ≥1.5 mg/dL or glomerular filtration rate <60 mL/min) by family doctors was 9,761 patients, 0.87 patients per 1,000 inhabitants.

In the 1980s, three population-based screening studies were performed to define the burden of chronic renal failure in different regions of Cuba. The prevalence rate was 1.1, 3.3, and 3.5 per 1,000 inhabitants, respectively. At present, another three population-based screening studies are ongoing in order to detect the chronic kidney disease in earliest stages.

The continuing medical education activities have been very useful in raising the awareness of medical doctors and the basic health staff about the threats posed by and the strategies to prevent, diagnose, and treat chronic kidney disease.     

Current structure and organization for renal patient assistance in Italy

Background. Given the public health challenge and burden ofchronic kidney disease, the Italian Society of Nephrology (SIN)has compiled a national census of Renal Units (RU) existingin the twenty Italian regions related to the year 2004. Methods. An on-line questionnaire including 158 items exploredstructural and human resources, organization aspects, activitiesand epidemiological data in SIN, 2004. Results. The census identified 363 public RU, 303 satelliteDialysis Centres (DC) and 295 private DC totalling 961 DC [16.4per million population (pmp)]. The inpatient renal beds were2742 (47 pmp). Renal and dialysis activity was performed by3728 physicians (64 pmp), of whom 2964 (80%) were nephrologists.There was no permanent medical assistance in 41% of satelliteDC. There were 1802 renal admissions pmp and 99 renal biopsiespmp. The management of acute renal failure (13 456 cases;230 pmp) represented a relevant proportion of the activitiesconducted in public RU. In 2004 there were 9858 new cases ofend-stage kidney disease requiring renal replacement therapy(RRT) (169 pmp). On 31 December 2004, 60 058 patients wereon RRT (1027 pmp), 43 293 of which (740 pmp) were on dialysisand 16 765 (287 pmp) with renal graft. Conclusions. This census of the Italian RU and DC in 2004 providesdecision makers and healthcare stakeholders with detailed datafor benchmarking and has financial implications for the publichealth system. Similar analyses may be conducted in other countriespermitting standardization of medical and cost-related aspectsof renal care.     

Network and epidemiologic information in nephrology: Kidney report 2009

In 2009, 8,560 patients with end-stage renal disease living in 20 regions (Alsace, Auvergne, Bourgogne, Bretagne, Centre, Champagne-Ardenne, Corse, Haute-Normandie, Ile de France, la Réunion, Languedoc-Roussillon, Limousin, Lorraine, Midi- Pyrénées, Nord-Pas de Calais, Pays de Loire, Picardie, Poitou- Charentes, Provence-Alpes C?te d'Azur and Rh?ne-Alpes) covering 57 million inhabitants (89% of the French population), started renal replacement therapy (dialysis or preemptive graft): median age was 70,2 years ; 3,4% had a preemptive graft. The overall crude annual incidence rate of renal replacement therapy for end-stage renal disease was 150 per million population (pmp), with significant differences in sex and age-adjusted incidence across regions (99 to 389 pmh). At initiation, more than one patient out of two had at least one cardiovascular disease and 41% diabetes (92% Type 2 non-insulin-dependent diabetes). On December 31, 2009, 33,558 patients living in the above 20 regions were on dialysis : median age was 70,5 years. On December 31, 2009, 29,181 patients were living with a functioning graft : median age was 54,8 years. In these 20 regions, the overall prevalence of dialysis was 588 pmp, that of renal graft, 510 pmp and the overall rate of renal replacement therapy for end stage renal disease, 1,098 pmp with significant differences in age-adjusted prevalence across regions (809 to 2,709 pmh). In the 2002-2009 cohort of 43,433 incident patients, the overall one-year survival rate was 83%, 45% at 6 years. Survival decreased with age, but remained above 50% at 2 years in patients older than 75 at RRT initiation. Among the 8,688 new patients starting dialysis in 2009 in 23 regions (the 20 regions mentioned above, plus Aquitaine, Pays de Loire and Guadeloupe), 5% had a BMI lower than 18,5 kg/m2 and 20% a BMI higher than 30. At initiation, 66% had a haemoglobin value lower than 11 g/l and 10% an albumin value lower than 25 g/l. The first haemodialysis was started in emergency in 33 % of the patients and with a catheter in 54 %. On December 31, 2009, 7 % treated in the dialysis units of the 22 regions (the 20 regions mentioned above, plus Aquitaine and Pays de Loire) received peritoneal dialysis, of which 40% were treated with automated peritoneal dialysis. 95% of the patients on haemodialysis had 3 sessions per week, with a median duration of 4 hours. In the 2002-2009 cohort of incident patients in 18 regions under 60 years, the probability to be at least once on the waiting list for a renal graft is 50% at 15,6 months. In 2009, 2,750 patients received a renal graft. On December 31, 2009, 7,272 patients were on the waiting list for a renal graft in the transplantation centres of the 22 regions. The analysis of the flows between treatments indicates that the proportion of the transplanted patients among RTT patients is increasing. The main source for transplantation is the outcenter patients.     

Preemptive Kidney Transplantation—A Team Experience in Uruguay

Kidney transplantation is the best treatment for end-stage chronic renal disease. In Uruguay, the prevalence of patients on dialysis is 757 patients per millon inhabitants, plus 316 alive with a functioning renal graft. We install a preemptive renal transplantation program. Twenty-five patients received grafts without dialysis from 2004 to 2013, 5 receiving their 2nd transplantation and 17 from cadaveric donors, with 7.4 ± 7.7 months in the waiting list. At 24 months, patients' survival rate was 100% and the grafts' 97%, with a serum creatinine of 1.4 ± 0.6 mg%. The developed programs of dialysis and renal health care contributed install our preemptive kidney transplantation. Kidney transplantation should be proposed to selected patients with chronic renal failure as primary therapy of substitution of renal function.     

Disparities in end-stage renal disease care in South America

South America is one of the most heterogeneous regions in the world regarding ethnical composition and socioeconomic development level. Our aim was to analyze the status of end-stage renal disease (ESRD) management in the Portuguese-speaking and Spanish-speaking countries of South America. Data were collected using a survey sent to the Society of Nephrology of each country, and complemented with data available in the Latin American Dialysis and Transplant Registry or personal communication with collaborators within the nephrology societies. Most of South America countries have a hybrid of public and private healthcare system. Universal access to renal replacement therapy (RRT) is provided in Argentina, Brazil, Chile, Uruguay and Venezuela which comprise nearly 73% of South America population. The expenditure on health per capita varies from nearly US$ 200 per year in Bolivia to more than US$ 1,600 per year in Argentina. The prevalence of patients on RRT varies from 95 pmp. in Paraguay and 924 pmp in Chile. There is an important association between the prevalence of diabetes and the number of patients on RRT. Older people also are at a higher risk of developing ESRD. The rapid aging of the population and a higher prevalence of diabetes will probably translate into a burden of ESRD in the future. It is to be hoped that political and economical stability in the region can ease the adoption of universal access to ESRD treatment in all South American countries.     

Activity of transplant coordination in Uruguay

The purpose of this study was to analyze the evolution of donation and organ transplantation in Uruguay, after the initiation of a program of transplant coordination, which began in 2000. The total number of effective donors increased from 28.7 per million people (pmp) in 2000 to 48.1 pmp in 2005, which constituted an increase of 75%. The number of real donors also increased from 10 pmp in 2000 to 20.6 pmp in 2005, more than a 100% increase, with a cadaveric renal transplantation rate of 36 pmp (2005). The conversion of effective to real donors (RD/ED) increased from 0.125 to 0.42. Familial refusal decreased from 62.1% in 2000 to 19% in 2005, which constituted a decrease of 70%. We concluded that implementation of transplant coordinators and involvement of intensive care medical doctors in coordination have had a strong impact on these results.     

1996 Hong Kong Renal Registry Report

Summary: This report was based on the data from the Renal Registry of the Hospital Authority of Hong Kong and accounted for approximately 90-95% of all the patients on Renal replacement therapy (RRT) in Hong Kong. Patients receiving treatment under the private sectors were not included in this report. the data were as of 31 December 1996. There were 15 renal units (2.4 unit per million population [pmp]) and four major renal transplant centres. the number of patients on RRT was 3337 (530 pmp), of which 56% (299 pmp) were on peritoneal dialysis (PD), 15% (79 pmp) on haemodialysis (HD) and 29% (152 pmp) with functioning kidney transplants (TX). the net increase in the number of patients on RRT was +12% from the previous year. the incidence of end stage renal failure was 640 (102 pmp). the median age of patients on RRT was 49 years, of which 27% were above the age of 61 years. For new patients who commenced on RRT during 1996, the median age was 56 years, of which 36% were above the age of 61 years. the causes of renal failure were glomerulonephritis 37%, unknown 30%, diabetes 13%, inherited and congenital 5%, infection/reflux 3%, hypertensive/renal vascular disease 3%, urolithiasis 2%, obstructive 1% and others 5%. For new patients entered into the programme during 1996, 25% were due to diabetic nephropathy. Ten per cent of all the patients on RRT were serologically positive for hepatitis B infection (PD 12%, HD 6%, TX 9%). 5% of all the patients on RRT were positive for hepatitis C infection (PD 3%, HD 12%, TX 7%). Seventy-nine per cent of all the patients on dialysis were on PD (1885 patients, 299 pmp), of which 96% were on CAPD. Thirty-eight per cent of the patients on CAPD were on straight-line systems, 35% on disconnecting systems and 20% on UV flash systems. Four-hundred and ninety-five patients (79 pmp) were on HD, of which 59% were on hospital based HD, 15% on satellite centre based HD, 10% on charitable centre based HD and 5% on home HD. Nine-hundred and fifty-seven patients (152 pmp) had a functioning kidney graft. 542 (57%) were transplanted in Hong Kong, of which 50% were cadaveric kidney transplantations. During 1996, 121 patients (19 pmp) received a kidney transplantation. Eighty-four transplants were performed in Hong Kong, of which 58 were with cadaveric kidneys and 26 with living related kidneys. the annual mortality rate for all RRT was 7.3% (10% for PD, 8% for HD and 1% with TX). the major causes of death were infection (28%), cardiovascular (26%) and cerebral vascular accident (9%). Outcome indicators were on patients entered into the RRT programme during 1995, thus allowing for 1 year of follow up. For CAPD as the first RRT, 1 year patient and technique survival (censored for death and non-technique failure) were 94% and 93%. For living related kidney transplants performed in Hong Kong, 1 year patient and graft survival (censored for death) were both 100%. For cadaveric kidney transplants, 1 year patient and graft survival were 98% and 96%     

2017 Annual Report Digest of the Renal Epidemiology Information Network (REIN) registry

The French Renal Epidemiology and Information Network (REIN) registry started in 2002 with the goal to provide a tool to evaluate renal replacement therapy (RRT) practices and outcomes, to provide data for research and to support public health decisions related to end‐stage renal disease ESRD. This summary presents the incidence and prevalence of RRT including kidney transplantation and wait‐listing activity in 2017, and patients’ survival and trends over 5 years. In 2017, 11 543 patients started RRT for ESRD, that is, incidence of 172 pmp. Between 2012 and 2017, the incidence of RRT increased by 1% per year [CI 95% (0.0; +2.0)]. On 31 December 2017, 87 275 patients were receiving RRT, that is, prevalence of 1294 pmp, 55% on dialysis, 45% with a functioning transplant. In 2017, 3782 kidney transplantations have been performed including 16% from a living donor, 13% being retransplantations and 15% pre‐emptive transplantations. The median time on the waiting list was 19.7 months when only taking into account active waiting periods on the list. In 2017, 5280 new patients were registered on the renal transplant waiting list (i.e. 78.7 pmp). The number of patients considered as ‘inactive’ represented 45% of the patients on the list.     

Modelling future renal dialysis requirements under various scenarios of organ availability in Australia

SUMMARY: The rate of dialysis uptake in Australia has been increasing and in 1996 was 77 per million people per year (pmp). The rate of kidney transplantation in Australia is at the same time falling. We have developed a computer model to enable predictions of the number of dialysis patients to 2007, under several scenarios of organ availability. We also aimed to examine the cost implications of the predictions. The number of existing and new dialysis and transplant patients was obtained from the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) for the years 1988–95. Age‐stratified transition coefficients for dialysis uptake, transplantation, graft failure and dialysis and transplant death were calculated for this time period. Data from 1995 were used as the baseline year in the application of the model and the calculated transition coefficients applied for this year. Scenarios of organ availability examined were the current trend continued, stabilization of the current Australian rate (23 pmp), the South Australian rate (35 pmp) achieved nationally and the Spanish rate (47 pmp) achieved nationally. Validation of the model using 1997 data was performed. Direct costs for dialysis and transplantation were obtained from a major teaching hospital in Melbourne. The number on dialysis is predicted to increase from 5648 in 1998 to 11 803 by 2007. If the transplant rate is increased from 23 pmp to ‘the world best practice transplantation rate’ (47 pmp) the predicted dialysis number in 2007 would be 8476. This is associated with a direct cost saving in comparison to the current trend of 82 million dollars (1998 Australian dollars). Assuming the Australian population increases as predicted and that current trends in dialysis uptake and transplantation continue, dialysis numbers are predicted to more than double over the next 10 years. In order to limit the potential human and economic cost of renal replacement therapy, this model indicates that attempts to increase organ availability are worthwhile.
