Background

In the UK, elderly patients represent the most rapidly expanding group of the dialysis population. However, there remains little evidence to suggest improved quality of life or increased life expectancy, particularly in those over 80 years old.

Methods

We retrospectively reviewed patients who were initiated on haemodialysis (HD) between January and October 2019 in a tertiary renal centre in the United Kingdom. Data were collected using an electronic database. Baseline characteristics, 3 and 12-month mortality were recorded. Data were presented as counts with percentages and mean +/- SD.

Results

There were 263 patients initiated on HD, of which 120 (45.6%) were over 70 years; 67 were aged 70-79 years (group A) and 53 were aged 80-90 years (group B). Mean age was 78.1 ± 5.3 years and 74% were of white ethnicity. Baseline characteristics are summarized in table 1. Sixty patients remained on HD, 14 recovered, 6 moved to other modalities and 40 died. The 90-day mortality was 21% (18% in group A, 25% in group B); 6-month mortality was 27% in group A and 34% in group B; 1-year mortality was in 36% in group A and 35% in group B. In those established on HD (>90 days), 1-year mortality was 12% (17% in group A, 4% in group B).

Conclusion

We report a high 1-year mortality of 35% in the elderly population. However, the majority occurred during the 1st 90 days. For those established on HD, mortality is 12%; this is substantially lower than the UK renal registry data for over 75s which was 23% in 2017. Mortality was comparable between age groups, although we were limited by small sample size. A key question is whether there is a difference in quality of life and life expectancy in this cohort.
