Mortality from renal diseases in Finland

Area of Science:

• Nephrology
• Epidemiology
• Public Health

Background:

• Mortality from renal disease in Finland exhibited a concerning rise in the mid-20th century.
• The role of analgesic overuse, specifically phenacetin, was hypothesized as a contributing factor to increased renal deaths.
• Advancements in renal replacement therapies have shown promise in mitigating mortality rates.

Purpose of the Study:

• To analyze trends in renal disease mortality in Finland from 1951 to 1982.
• To investigate potential factors influencing these mortality trends, including medical interventions.
• To assess the impact of renal dialysis and transplantation on survival rates.

Main Methods:

• Retrospective analysis of mortality data related to renal disease in Finland.
• Examination of temporal trends in mortality rates over a 30-year period.
• Correlation of mortality data with the availability and utilization of renal replacement therapies.

Main Results:

• Overall renal disease mortality increased until 1962, followed by a subsequent decrease.
• While phenacetin use was suspected, direct evidence linking it to the mortality increase was not definitive.
• Renal dialysis and transplantation significantly reduced mortality rates.
• In the early 1980s, a substantial proportion (50%) of renal disease deaths in individuals under 70 occurred without these treatments.

Conclusions:

• Renal replacement therapies have dramatically improved survival for patients with renal disease.
• The potential for further mortality reduction exists through unrestricted access to dialysis and transplantation.
• Public health strategies should focus on ensuring equitable access to advanced renal care to prevent premature deaths.
