= 46), a global collaboration examining the association between medical and non-medical factors and RRT incidence, modality mix and survival. Numbers of incident and prevalent patients were collected for current (2003–05) and historic (1983–85, 1988–90, 1993–95 and 1998–2000) periods stratified, where available, by age, gender, treatment modality and cause of end stage renal disease (diabetic <italic>versus</italic>
non-diabetic). General population age and health indicators and national-level macroeconomic data were collected from secondary data sources. National experts provided primary data on renal service funding, resources and organization. The median (inter quartile range) RRT incidence per million of the population (pmp) was 130 pmp (102–167 pmp). The general population life expectancy at 60 was 22.1 years (19.7–23.1 years) and 6.9% had diabetes mellitus (5.4–9.0%). Healthcare spending as a percentage of gross domestic product was 8.1% (5.6–9.3%). Countries averaged nine dialysis facilities pmp (4–12 pmp), with 69.0% (43.9–99.0%) owned by the public or private not-for-profit sector. The number of nephrologists ranged from 0.5 to 48 pmp (median 12 pmp). The heterogeneity of EVEREST countries will enable modelling to examine the independent association between medical and non-medical factors on RRT epidemiology.</p>

<abstract><p>Rates of initiation of renal replacement therapy (RRT), use of home modalities of treatment and patient outcomes vary considerably between countries. This paper reports the methods and baseline characteristics of countries participating in the EVEREST study (<italic>n</italic>
= 46), a global collaboration examining the association between medical and non-medical factors and RRT incidence, modality mix and survival. Numbers of incident and prevalent patients were collected for current (2003–05) and historic (1983–85, 1988–90, 1993–95 and 1998–2000) periods stratified, where available, by age, gender, treatment modality and cause of end stage renal disease (diabetic <italic>versus</italic>
non-diabetic). General population age and health indicators and national-level macroeconomic data were collected from secondary data sources. National experts provided primary data on renal service funding, resources and organization. The median (inter quartile range) RRT incidence per million of the population (pmp) was 130 pmp (102–167 pmp). The general population life expectancy at 60 was 22.1 years (19.7–23.1 years) and 6.9% had diabetes mellitus (5.4–9.0%). Healthcare spending as a percentage of gross domestic product was 8.1% (5.6–9.3%). Countries averaged nine dialysis facilities pmp (4–12 pmp), with 69.0% (43.9–99.0%) owned by the public or private not-for-profit sector. The number of nephrologists ranged from 0.5 to 48 pmp (median 12 pmp). The heterogeneity of EVEREST countries will enable modelling to examine the independent association between medical and non-medical factors on RRT epidemiology.</p>

<p>Chronic kidney disease (CKD) consistently affects 10–15% of the general population [<xref rid="R1" ref-type="bibr">1–4</xref>
] yet the incidence of renal replacement therapy (RRT) varies from around 100–120 per million of the population (pmp) in the UK, Australia, New Zealand and the Netherlands to 350–450 pmp in Jalisco (Mexico), Taiwan and the United States of America [<xref rid="R5" ref-type="bibr">5</xref>
]. Variation in rates of progression of CKD to end-stage renal disease (ESRD) may explain some of these differences [<xref rid="R3" ref-type="bibr">3</xref>
], but other factors such as referral to renal services [<xref rid="R6" ref-type="bibr">6,7</xref>
], the decision to initiate dialysis [<xref rid="R8" ref-type="bibr">8</xref>
] and availability of resources [<xref rid="R9" ref-type="bibr">9</xref>
] are also likely to have played a part. There also seem to be associations with national wealth, spending on health care and health care system organization [<xref rid="R10" ref-type="bibr">10,11</xref>
].</p>
<p>Considering patients on RRT, the proportion of patients receiving each modality of treatment—haemodialysis (HD), peritoneal dialysis (PD) and transplantation—shows marked variation around the world. In 2006, around 80% of prevalent patients were receiving PD in Hong Kong and Jalisco (Mexico) compared with less than 5% in Japan, Bangladesh and Luxembourg and rates of home HD ranged from <1% in many countries to 16% in New Zealand [<xref rid="R5" ref-type="bibr">5</xref>
]. Studies that have previously examined these differences have highlighted the role of health care organization and spending [<xref rid="R11" ref-type="bibr">11–13</xref>
] as well as the relative cost of staff and consumables [<xref rid="R14" ref-type="bibr">14,15</xref>
] and physician training [<xref rid="R16" ref-type="bibr">16</xref>
] and attitudes [<xref rid="R17" ref-type="bibr">17,18</xref>
].</p>
<p>There also appear to be marked international differences in survival on dialysis [<xref rid="R19" ref-type="bibr">19</xref>
], which persist after adjustment for casemix [<xref rid="R20" ref-type="bibr">20</xref>
]. Recognition of the need to understand these differences was the driving force behind the Dialysis Outcomes and Practice Patterns Study (DOPPS) [<xref rid="R21" ref-type="bibr">21</xref>
]. Although DOPPS is restricted to in-centre haemodialysis, it investigates a large number of potential explanatory variables at the individual level including patient casemix and processes of care. At a broader level, however, the characteristics of the general population or of the health care system and inequalities in access to renal services [<xref rid="R12" ref-type="bibr">12</xref>
,<xref rid="R22" ref-type="bibr">22</xref>
] may also explain some of the variations in RRT survival [<xref rid="R23" ref-type="bibr">23,24</xref>
].</p>
<p>The EVEREST study (Explaining the Variation in Epidemiology of RRT through Expert opinion, Secondary data sources and Trends over time) aims to examine in a wide range of countries worldwide the influence of medical and non-medical factors on (1) current RRT incidence, (2) changes in RRT incidence over time, (3) RRT modality mix and (4) survival on RRT and to attempt for the first time to quantify the strength of any associations that persist after adjusting for differences in casemix. This paper describes the methods that have been adopted to collect the study data and describes the baseline characteristics of the participating countries.</p>

<sec sec-type="methods" id="S2"><title>Methods</title>
<p>Primary and secondary data have been collected as part of the study—primary data on renal service organization, funding and resources and secondary data on population age and health indicators, macroeconomic indicators and RRT epidemiology.</p>
<p>All renal registries that were known to have reported data on the epidemiology of RRT at a national level were approached and invited to take part in the study. If national-level data were not available regional registries were approached. For reasons partly related to concerns about independence of the observations and partly related to availability of macroeconomic data, the study group decided at its first meeting to adopt a strict policy of including only one observation for each country. This was despite logical arguments for some countries—such as the UK, Spain, Italy, Belgium, the USA—that regional differences exist that will be lost if analysis is done at too high a level. Local approval was obtained, where appropriate, for collaboration in the study.</p>
<sec id="S2-1"><title>Dependent variables—incidence of RRT, treatment modality and patient survival</title>
<p>Renal registry data were collected in two ways:
<list list-type="bullet"><list-item><p>Some renal registries were annually submitting individual patient data to the ERA-EDTA Registry in Amsterdam at the time of data collection (Table <xref ref-type="table" rid="T1">1</xref>
). For these countries it was only necessary to inform the registries of the plan to undertake the study and ask for their collaboration; but no additional renal registry data collection was required.</p>
</list-item>
<list-item><p>For renal registries not routinely providing individual patient data to the ERA-EDTA Registry, incidence, prevalence and population data were collected specifically for the study in an electronic spreadsheet with cross-checks built in to optimize accuracy and consistency of the data. Data were collected in five gender-specific age-bands (0–19, 20–44, 45–64, 65–74 and > = 75 years). Where data were not available at this level they were collected in two age-bands (<65 and > = 65 years) or non-stratified.</p>

<p>Data were collected (where available) for five study periods: 1983–1985, 1988–1990, 1993–1995, 1998–2000 and 2003–2005. Three-year study periods were chosen to ensure stability of measurements. Incidence of RRT was defined as the number of patients commencing RRT for the first time during the study period and prevalence as the number of patients alive on RRT on 31st December of the mid-year of the study period. Total incidence of RRT and incidence of RRT for ESRD secondary to diabetic nephropathy were collected at Day 1, although it should be noted that not all registries capture patients commencing RRT with a pre-emptive transplant (Table <xref ref-type="table" rid="T1">1</xref>
). Data on RRT modality mix were collected for incident patients alive on RRT 91 days after the initiation of RRT (HD, PD and renal transplant) and prevalent patients alive on RRT on 31st December of the mid-year of the study period (centre HD, home HD, PD and renal transplant). Registries also provided age-gender stratified data for the covered general population. For each study period, incidence rates and prevalence pmp were calculated by dividing the sum of the observed counts during the study period by the sum of the covered general population in this study period.</p>
<p>For registries with individual patient data, survival tables (using Kaplan Meier) were collected for patients alive and still requiring RRT 91 days after the initiating treatment in the study period 2003–2005, with follow-up to 31st December 2006. Separate survival tables were collected for individuals under and over 65 years of age and those with and without diabetes as the cause of ESRD. All survival tables were also collected separately with and without censoring for transplantation.</p>

<sec id="S2-2-2"><title>Macroeconomic indicators.</title>
<p>National-level macroeconomic data were collected from a number of international secondary data sources (Box <xref ref-type="table" rid="T3">1</xref>
) or, with the assistance of the collaborating renal registry, from the respective offices of national statistics.</p>
<p>One of the indicators, the United Nations Development Programme Human Development Index (HDI), was collected based on a prior belief that the association between independent variables and RRT incidence was likely to be related to a nation's state of economic and social development. For three variables—the WHO Responsiveness Index, the Gini Coefficient and the HDI—only one measure was collected for the current study period and none were collected for the historic study periods. For the other macroeconomic variables, data were collected for each of the five 3-year study periods (see above) and the average taken to derive a single variable for each 3-year study period.</p>
</sec>
<sec id="S2-2-3"><title>Renal service organization indicators.</title>
<p>Although some of the renal service variables (Box <xref ref-type="table" rid="T4">2</xref>
) were routinely collected by state healthcare administrations or professional organizations, locating these data and judging their validity required local knowledge and expertise. Further, many of the renal service variables were not routinely collected or required an element of nation-specific expert opinion. For these reasons it was decided that an expert would be needed in each country to assist in the collection of these data.</p>
<p>National experts were identified through national renal registries usually with approval by the relevant national society of nephrology. The initial correspondence to the collaborating renal registry advised that the national expert would need considerable experience in renal service provision and planning at a high level, to be able to locate and collect the required data and be able to give responses at a national level. As we were collecting historical data (back to 1983) it was felt that the national expert needed to have been working in nephrology for at least 20 years.</p>
<p>A questionnaire (English language) was developed to collect the national expert data. This was piloted in the UK, modified slightly and then further piloted in The Netherlands and Romania. National experts were then allocated to an EVEREST co-investigator (ACo, ACu, AM, BS, FC or KJ) to work with them to complete the questionnaire through a combination of telephone meetings and email correspondence. Where possible, EVEREST co-investigators were matched to national experts who spoke their first language.</p>
<p>It was recognized that having the study formally approved might optimize response rates and this was achieved at a global level through official endorsement of the study by both the European Renal Association-European Dialysis and Transplantation Association (ERA-EDTA) and the International Society of Nephrology (ISN).</p>
<p>Six items to be collected by the national experts were considered difficult to capture and particularly sensitive to personal opinion. For those items Likert scale-style questions were included in the national expert questionnaire to provide a semi-quantitative way of measuring these variables (Box <xref ref-type="table" rid="T4">2</xref>
). The answering mode to these questions took the form of a horizontal line, on which the respondent would indicate his or her response by checking 1 of 10 tick boxes from 0 to 10. These responses were subsequently categorized into rarely (0–1), sometimes (2–8) and often (9–10). When a national expert felt unable to provide a single, national-level response for one of these Likert scale-style questions, he or she arranged for short regional questionnaires (containing the six region-specific Likert scale-style questions) to be completed by one or more regional expert(s). A national-level score was then calculated by weighting the regional responses according to the proportion of the national population represented by each region.</p>

<p>Countries had an average of nine dialysis facilities pmp (IQR 4–12 pmp), with a median of 69% owned by the public or private not-for-profit sector. The decision to set up a new haemodialysis facility was controlled in some way by the state in 52% of countries—in 11% the decision was based on an assessment of need and in 41% it was based on availability of funding. National experts reported high levels of perceived competition for patients between centres in 41% of countries and high levels of perceived choice of dialysis facility amongst patients in 52% of countries. The number of whole time equivalent nephrologists ranged from 0.5 to 48 pmp (median 12 pmp). Nephrologists were considered to earn, on average, at least 25% more than non-renal hospital specialists in 35% of countries (and at least 25% less in 4% of countries).</p>
<p>Non-referral of elderly, co-morbid patients to a nephrologist was considered ‘rare’ in 39% of countries. Distance from a dialysis facility was reported as ‘sometimes’ a reason for choosing PD rather than HD in 67% of countries and in elderly co-morbid patients distance was reported as ‘sometimes’ a reason for choosing not to have dialysis in 39% of countries. Access to haemodialysis was reported as ‘sometimes’ or ‘often’ restricted due to lack of haemodialysis facilities in 33% and 6% of countries, respectively.</p>

<sec sec-type="discussion" id="S4"><title>Discussion</title>
<p>To date, efforts to understand the worldwide variation in RRT incidence have relied on qualitative work describing the factors and policies that may have influenced RRT treatment rates. Various perspectives have been taken. In the 1990s, De Vecchi adopted a top-down approach with measures of health care spending and health care organization from a number of industrially developed countries [<xref rid="R10" ref-type="bibr">10</xref>
]. More recently, a broader and more detailed, but still descriptive, approach was applied to the 12 DOPPS countries by its health economics subgroup [<xref rid="R25" ref-type="bibr">25</xref>
]. An alternative approach, systematically targeting the various stages in the pathway towards receiving RRT, was adopted in a study exploring the reasons behind the higher RRT incidence in Germany compared to England and Wales [<xref rid="R26" ref-type="bibr">26</xref>
]. While such approaches provide interesting anecdotes and can be hypothesis generating, they are unable to comment on the relative importance of individual medical or non-medical factors—for this, quantitative data for each potential explanatory factor, collected in a large number of countries, are required.</p>
<p>The EVEREST study takes such a systematic approach, collecting quantitative data for a broad range of countries worldwide. By simultaneously collecting general population age and health indicators and macroeconomic measures alongside quantitative data on renal service organization and resources, it will be possible to study which of the variables collected have the strongest effect on the study outcomes having adjusted for relevant confounders.</p>
<p>The countries included in EVEREST are markedly heterogeneous in their RRT incidence, general population demographics and macroeconomic statistics as well as in the organization of their renal services and availability of resources. This heterogeneity is important as it will improve the power of the study in multivariate model building. Historical data, which will provide further heterogeneity, will be important for two reasons. Firstly, a country's current RRT incidence is likely to be influenced by previous health policy and resource availability. And secondly, the influence of non-medical factors on adoption of medical technologies is likely to evolve over time and at different rates depending on a nation's wealth and health care spending [<xref rid="R27" ref-type="bibr">27</xref>
]. To be able to examine this, EVEREST has collected data for many items going back to 1983.</p>
<p>The high response rate from registries and national experts in renal services is testament to the international interest there is in understanding the marked differences in RRT epidemiology. Although many of the national expert variables were purely quantitative (e.g. number of nephrologists, numbers of dialysis units, costs, reimbursement rates and salaries), a small number attempted to capture quantitatively elements that were related to process (e.g. how much control the state has over setting up a new dialysis facility and how much competition there was between dialysis providers).</p>
<p>The six Likert scale questions attempted to capture more complex situations such as healthcare seeking behaviour and access to healthcare (e.g. non-referral of elderly, co-morbid patients to renal services) to which the replies could only be semi-quantitative. While the Study group recognized from the outset that a single individual's attempt to summarize these national-level system characteristics was potentially of limited validity, it was considered important to explore these areas to keep them on the research agenda. The experience gained in this attempt will be useful when designing future studies. However, given the uncertainty about the validity of the responses it is unlikely that these data items will be included in any of the main EVEREST models.</p>
<p>Supplementary free-text data (from notes made during interviews or added by national experts) collected alongside the quantitative data, although difficult to analyse, will provide invaluable depth and validity to the findings and provide an opportunity to identify factors not previously considered.</p>
<p>The EVEREST dataset has been collected primarily to provide insight into the role that non-medical factors play in explaining the worldwide variation in current RRT incidence, changes in RRT incidence over time, RRT modality mix and RRT survival. These analyses are likely to identify factors that are worthy of closer scrutiny. The study has already demonstrated the willingness of nephrologists and renal registries to collaborate on an international scale in order to resolve potential inequity in access to and outcomes on RRT.</p>
