Deaths from kidney diseases were retrieved by record linkage with the Causes of Death Register. Regional information on age-adjusted prevalence of kidney disease (indicator of demand for care), current healthcare expenditure per capita, and number of nurses and beds in dialysis units (indicators of renal care supply) per million residents were selected as contextual variables. Regional differences in kidney disease-related mortality taking or not into account these contextual indicators were evaluated using a multilevel approach.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Age-adjusted kidney disease-related mortality rates were higher than the national average for males and females in the largest southern regions.
