Methods. A questionnaire was mailed to the presidents of each of 43 national renal paediatric societies or working groups in Europe. Data on each country's population, income as reflected by its gross national product and infant mortality rate, were obtained from the United Nations. The paediatric health care systems were previously divided into three types: general practitioner care system, paediatric care system and combined care system (CCS).
Results. In 1998, 842 specialized paediatric nephrologists worked in hospitals in 42 European countries. The median number of paediatric nephrologists per million child population (pmcp) was 4.9 (range 015). The median number of children served per paediatric nephrologist was significantly higher in countries with the general practitioner care system than in those with the paediatric or combined care system (CCS), namely 370 747 vs 169 456 and 191 788, respectively. In addition to specially trained paediatric nephrologists, there were 1087 paediatricians with a part-time interest/activity in paediatric nephrology in hospitals in 34 European countries. Eastern European countries had significantly more general paediatricians with part-time nephrological activities than countries belonging to the European Union (EU), 16.7 vs 6.6 pmcp. In 1998, 92% of 42 European countries offered paediatric dialysis facilities for acute renal failure and 90% for chronic renal failure and 55% offered paediatric renal transplantation (RTx). Only 30% of Eastern European countries (central omitted) offered paediatric RTx vs 87% of EU countries. The availability of paediatric RTx was associated significantly with the countries gross national product (r = 0.53, P<0.001). The median number of paediatric hospitals offering dialysis for childhood chronic renal failure was 1.5 pmcp (range 05.0) and the median number of paediatric hospitals offering paediatric RTx was 0.4 pmcp (range 03.5). Fewer children were on dialysis or were transplanted in Eastern European countries than in the EU.
Conclusions. At the end of the 20th century, there was a marked variation in delivery of paediatric renal care within Europe. This was related to factors such as size of the population, geographical and political situation, the type of primary paediatric care system and economic situation. European countries were far from equal with regard to access of renal replacement therapy for children. Improvement of the economic situation is beyond the capabilities of paediatric nephrologists. However, in these days of world-wide globalization paediatricians in greater Europe should be able to achieve better cooperation and exchange of ideas and information which would be the first step towards equality of renal care for children.

Specialists
The total number of paediatric nephrologists in 42 European countries reported at the end of 1998 was 842, serving a child population <15 years of age of 169 million. In addition, there were 1087 general paediatricians with a part-time interest/activity in paediatric nephrology. Together with the specialized paediatric nephrologists, they provided basic renal care to approximately 150 million children <15 years of age in 34 out of 42 countries; no report was received from eight of these countries. The median number of specialized paediatric nephrologists was 4.9 pmcp (range 015) in 42 countries and the median number of general paediatricians offering renal care was 5.8 pmcp (range 045) in 34 countries (Table 1). Five of the 42 countries (Cyprus, Estonia, Iceland, Luxembourg, Malta) had no paediatric nephrologists, and renal care for children was supplied either by general paediatricians or by adult nephrologists (Table 2). Paediatric nephrologists were the only paediatricians seeing children with kidney disease in both the UK and Ireland. Excluding the five countries without specialized paediatric nephrologists, the number of children served by one specialized paediatric nephrologist ranged from 67 130 to 878 940 in the remaining 37 countries. Incorporating the above data into the previously described paediatric care systems [1] the number of children per specialized paediatric nephrologists showed significant differences (P<0.05) between countries with the GPCS and countries with the PCS or the CCS (Figures 1 and 2). Eastern European countries had significantly more general paediatricians with a part-time interest/activity for children with kidney diseases than European Union (EU) countries [16.6 vs 6.6 pmcp (P<0.05)]. The median ratio of specialized paediatric nephrologists to all practicing paediatricians in Europe was 1:145 (range 1:401:583) (Table 1). In countries with PCS the mean ratio of specialized paediatric nephrologists to practicing general paediatricians was significantly lower than in countries with the CCS and the GPCS (Figure 2 and Table 2).

The median number of paediatric hospitals offering dialysis for childhood ARF was 3.5 per country, range 030. The median number of paediatric hospitals offering dialysis for ARF was 1.7 pmcp (range 06.2). In 20 Eastern European countries the median number of hospitals offering dialysis for ARF in children was 1.7 vs 2.2 in 15 EU countries. These differences were not significant. The number of paediatric hospitals offering dialysis for ARF correlated positively to the size of the child population <15 years of age (r = 0.72, P<0.001) and to the number of paediatric nephrologists in the specific area/country (r = 0.71, P<0.001) (Figure 3); there was no association between the number of hospitals equipped to treat ARF in childhood and the three types of paediatric care systems. Countries with a mortality rate for children <5 years below 8.5 had a significantly (P<0.001) higher number of hospitals (2.4 vs 1.2 pmcp) offering dialysis for ARF in children than countries with a mortality rate above 8.5.

Registry
In 1996, 28 out of 40 European countries (70%) reported data on RRT in their young patients either to a national and/or multinational registry. Fewer Eastern European countries than EU countries reported data on renal patients to the various registries (50 vs 100%). High quality registry data fulfilling the criteria of completeness and accuracy were not available for the majority of countries reporting to the registries. Unfortunately, our own data on children receiving either haemodialysis, peritoneal dialysis or a RTx in 1996 (Table 4) can also only be taken as an estimate given by the national representatives answering the questionnaire. Nevertheless, our data show without any doubt that considerably fewer children were dialysed or transplanted in Eastern European countries than in the EU.
|
Eighty-six percent of national representatives considered RRT essential for their patients with CRF. Representatives from Armenia, Georgia, Lithuania, Luxembourg and Moldavia stated that chronic RRT was not a national priority in paediatric care in 1998.
Congresses
Forty-eight percent of 42 countries reported having regular national paediatric nephrology congresses for their members, 33% had no regular meetings; no data were available for 19% of countries reporting.

To the best of our knowledge this is the first study undertaken to evaluate the demography of specialized paediatric renal care in these 42 European countries. In doing so, the paper answers the suggestions proposed in 1991 by our colleague Sir Cyril Chantler [2] who stated that the role of paediatric nephrologists in different European countries requires closer examination. He also proposed that Europe needs to agree upon appropriate and equal training in paediatric nephrology. In fact, ESPN recently published training recommendations, part of which is included in Appendix 2 [3]. Such a training programme has not yet been fully realized. Therefore, in 1998 and even at the time of writing (2003), the situation showed a great diversity in the ability and training of paediatric nephrologists in Europe, and even more among paediatricians with an interest in nephrological activities. When we, the authors, therefore write about these two categories of paediatric care-providers, we are well aware of the lack of homogeneity among these two groups. This is only one of the many problems we faced in accumulating the reported data which are long overdue. However, it must be realized that coordination between many countries and assuring the reporting of reliable data, has taken much more time than was anticipated. Our data, therefore, refer only to the state of renal paediatric care in 1998. We are presently in the process of updating these data. One of the major problems facing us when accumulating the above data, was the lack of demographic data on the incidence and prevalence of all renal diseases in childhood in Europe. We have reliable estimates, obtained from the European Dialysis and Transplant Association (EDTA) Registry in 1991, on the number of children starting RRT per year, which ranged between 5 and 14 children pmcp in different European countries [4]. When assuming a median number of eight children per year/pmcp we can predict, on the basis of these 12-year-old registry data, that 1000 children will probably have to start RRT every year in Europe.
There is a long-standing argument in the academic literature as to who should be the preferred doctor treating children with special, organ-centred, diseases. It has been argued by many paediatric nephrology societies that children should be treated by specialized paediatric nephrologists. Adult nephrologists have agreed with these demands as evidenced by the fact that in 1989 >90% of children <15 years of age with ESRD were treated in specialized paediatric nephrology centres in Europe [46]. In this regard we have to stress the differences found between the Eastern European and EU countries. The former had less paediatric nephrologists working in dialysis or transplantation and more paediatricians with part-time paediatric nephrology activities. The latter may be due to the fact that Eastern countries had more general paediatricians than Western countries [1]. Only 30% of Eastern countries offered RTx vs 87% of EU countries. In many Eastern European countries the care of children needing dialysis and RTx was not in the hands of paediatric nephrologists. Boesken et al. [7] and others [8] stated that there were three types of specialists practicing adult nephrology in countries of the former Soviet Bloc: a therapeutist (nephrologist), who treated general nephrology problems, a dialysis specialist who was often a surgeon, and a transplant surgeon. Renal biopsies were more often done by urologists than by nephrologists. This fragmentation of nephrology was also seen in Eastern European paediatric nephrology as reported by the presidents of national societies and working groups (personal communications). These differences lead to the conclusion that many paediatric nephrologists in Eastern Europe would not be considered paediatric nephrology specialists in EU countries. Considering the division of paediatric nephrology services in Eastern Europe, it is certainly reasonable to aim at an integration of services (the opposite of fragmentation) and this has recently effectively been achieved in the Czech Republic, Hungary and Poland [911]. In these countries this process took rather long because of: (1) the time needed to train the paediatric nephrologists, (2) realizing the necessary organizational steps which included convincing the authorities at government level of the reduced costs of integrated care, and (3) convincing national medical organizations to make changes in their training programmes.
It may well be that the 842 paediatric nephrologists together with 1087 paediatricians with renal interest, are enough to supply renal care to every child in Europe. However, many may still not be adequately trained. If training programmes are organized locally and are integrated by a central European body like the Union of the European Medical Subspecialists (UEMS), the overall situation should rapidly change for the better. This is one of the main recommendations of our paper. In addition to this recommendation, we strongly feel that the training programmes for paediatric nephrology should not in any way be related to any changes in the three paediatric care systems [1]. Differences in access to RRT are not only related to these defined three paediatric health care systems but also to GNP, and obviously the local health insurance systems of the various countries. Eighty percent of countries with the GPCS had public health insurance. Data from adult nephrology patients show that in comparison to the private and mixed systems, the public insurance system had a lower number of doctors involved in ESRD, lower take-on rates for RRT and a higher proportion of transplanted patients [12]. There is no reason to doubt that this also holds true for children with renal disease.
Health care expenses have grown steadily over the past 15 years, including those for RRT and specifically for RTx. It is thus not surprising that all current reform efforts centre on cost and cost control. Public health physicians and health policy makers evaluate many clinical interventions for their effectiveness. Few are as effective as RRT, without which patients with ESRD will die. Data on the cost of RRT in Europe are scant. Adult services were mainly evaluated and they do not link outcome measures with costs and resource use. Furthermore, they only analyse the direct cost of treatment modalities without assessing the whole spectrum of care in renal failure. RRT in children is known to be more expensive than in adults [13], due to many factors such as the higher numbers of doctors and nurses needed per treated child, more personnel for psychosocial care, teachers, growth hormone therapy and special diets for the very young. The total budgetary costs for all paediatric ESRD patients are, however, much less than for adults [14] for the simple reason that the incidence and prevalence of ESRD in children are much lower than in adults. The costs of various treatment modalities may vary from country to country and are undergoing rapid changes requiring continuous adaptation of position papers [15]. Vecchi et al. [16] attributed differences in modality selection such as haemodialysis or peritoneal dialysis to differences in micro-economics of the provider. Haemodialysis is a treatment with a high fixed cost (personnel and structure) whereas peritoneal dialysis is a treatment modality with low fixed costs but high variable costs (supplies) and less need for investment. This may be the reason why peritoneal dialysis was more expensive in Eastern than in Western European countries. To expand on this, it has to be realized that new pharmaceuticals, of which 90% are produced in 10 countries (Europe, Japan, USA), and all the necessary supplies for peritoneal dialysis including lines, bags, fluids, connectors, etc., have to be imported from Western countries. These variable costs constituted the majority of expenses for peritoneal dialysis in Eastern Europe whereas the fixed costs (e.g. salaries) were much less and therefore haemodialysis was often cheaper in Eastern Europe [6,17,18]. RTx remains the treatment of choice for children with ESRD, not only with regard to survival and quality of life, but also as far as long-term costs are concerned [13,19].
Europe, at the end of the 20th century was found to be unequal, as far as access of children and adolescents to RRT is concerned, both for ARF and CRF. This was proven to be due to different national financial constraints and local priorities in health care. To what extent the goal of equal access to RRT throughout Europe has to be modified is an issue for discussion. Very few of our reporting colleagues stated that RRT was not a priority in their country, possibly reflecting a gap between wishful thinking and reality. In some Eastern European countries, the numbers of dialysis and transplant facilities for adults have increased significantly in the last decade. The paediatric share of this development is not yet clear. In 1995, it was estimated that only 3% of all children with ESRD received appropriate treatment in countries of the former Soviet bloc [6]. In 1998, there were indications that fewer children than adults had access to RRT. The fact that, according to our data, 90% of all European countries provided paediatric dialysis for CRF but only 55% offered paediatric RTx, is disturbing. We have no explanation for this paradox. When reviewing national reports on RTx from Eastern European countries, several reasons were given for the underdevelopment of their RTx programmes. Slovenia had a low procurement of cadaveric kidneys. Albania was faced with financial constraints and a lack of infrastructure, trained personnel, and public cooperation [20,21]. In Romania all kidneys for RTx came from living related donors [22] whereas Polish paediatric surgeons reported in 1996 that only 0.8% of all kidney transplants and 7.9% of paediatric RTx were performed from living related donors [23].
In this paper we have discussed some aspects of the organization and delivery of paediatric renal care in Europe and the challenges awaiting European paediatric nephrologists in the years to come. These challenges include: more individual initiative and cooperation, regular and repeated international training courses organized by the ESPN in Eastern European countries, the establishment and continuous funding of rescue teams for treatment of (epidemic) paediatric ARF wherever these are needed, formation of an ethical consensus committee, a well functioning European registry and/or national registries, an agency for paediatric nephrologists (facilitating job opportunities throughout Europe), and a task force on standardization of diagnosis and therapy of renal diseases in children. Paediatric nephrologists should realize that, depending on the local circumstances, they may well not be the only primary care-givers for children with renal disease. They should therefore aim for cooperation with all necessary medical personnel and institutions, to obtain the best care for their patients. At the same time, they should continue in their time-honoured role, that of setting the standards in paediatric renal care.

Paediatric nephrologists are defined as licensed paediatricians with a minimum of 3 years training including experience in neonatology and intensive care plus a higher 3 years specialty training in paediatric nephrology in out- and in-patient settings (which may also include adult nephrology). Part of the 3 years may be obtained during the period of general paediatric training.
During the training the European Society for Paediatric Nephrology has suggested that a high standard of expertise should be obtained in:
The embryology of the kidney and the urinary tract.
The anatomy, histopathology and physiology of the kidney and its circulation under normal and abnormal conditions.
The pathology and pathophysiology of congenital and acquired diseases of the kidney and the urinary tract in the growing child.
The aetiology, symptomatology, diagnosis and differential diagnosis of congenital and acquired renal diseases in the fetus, infant, and child and their appropriate investigation by imaging, renal function tests and renal histopathology.
The performance or detailed knowledge of the following procedures:
renal biopsy, renal ultrasonography, renal clearance techniques,
peritoneal dialysis and haemodialysis, continuous haemofiltration,
dietary and drug adjustment for the treatment of paediatric renal disease and renal transplantation.
During the training period the trainee should acquire knowledge of the indications and management of surgical interventions in the urinary tract and of renal transplantation.
A good understanding of the causes of bladder voiding abnormalities, their cystometric investigation and their medical and surgical treatments.
A good understanding of the prevention, manifestations and management of psychosocial problems which arise in children with chronic renal disease and their parents/caretakers. This should include awareness of ethical issues.
Paediatricians with an interest in paediatric nephrology are defined as licensed general paediatricians with a special interest and part-time work in paediatric nephrology.
Within the primary care system for children we previously defined three subgroups according to the proportion of children aged <15 years seen by either paediatricians or family physicians/general practitioners (GPs) [1]:
The paediatric system has >75% of children under the care of paediatricians.
The general practitioner/family doctor system has >75% children seen by family physicians/GPs.
The combined system has both paediatricians and GPs offering primary care to almost equal numbers of children.
