Deaths from chronic kidney disease

Chronic kidney disease (CKD) contributed to 11% of all deaths in 2015, that is around 17,000 deaths, according to the AIHW National Mortality Database. CKD was the underlying cause of death in around 4,300 deaths (25% of CKD deaths). It was an associated cause of death in a further 12,800 deaths (75% of CKD deaths). 

Trends

Rates for CKD as the underlying and/or associated cause of death remained relatively stable between 1997 and 2015 (56 to 58 per 100,000 population).

On average, CKD was the underlying and/or associated cause of death in around 12,900 deaths per year between 1997 and 2015. This equates to death rates of 72–80 per 100,000 population for males and 42–48 per 100,000 for females (Figure 1).

The line chart shows that from 1997 to 2015, the rate of CKD deaths (as the underlying and/or associated cause) remained relatively. Male rates were consistently higher than female rates over this period.

Age and sex

In 2015, CKD death rates (as the underlying and/or associated cause):

  • Were overall 1.5 times as high among males as females (72 and 47 deaths per 100,000 population, respectively). Age-specific rates for males were higher than females across all age groups (Figure 2).
  • Increased with age, with half (50%) occurring in those aged 85 and over. CKD death rates for males and females were highest in the 85 and over age group (2,292 and 1,586 per 100,000, respectively)―4 times as high for both males and females aged 75–84 years (581 and 360 per 100,000, respectively) (Figure 2).

Figure 2: CKD deaths (underlying or associated cause), by age and sex, 2015

The vertical bar chart shows that in 2015, CKD deaths (as the underlying and/or associated cause) increased rapidly from age 75 for both males & females. Rates were highest in those aged 85 & over for both males & females, 4 times the rate for males & 5 times as the rate for females aged 75–84 years. Males had consistently higher rates than females across all age groups.

Variations among population groups

CKD death rates (as the underlying and/or associated cause of death) increased with remoteness and socioeconomic disadvantage, and were higher among Aboriginal and Torres Strait Islander people:

  • 1.8 times as high in Remote and very remote areas compared with Major cities (100 compared with 55 per 100,000 population, in 2013–2015). The gap in these death rates was greater for females than males—2.4 times as high for females (102 compared with 43 per 100,000) and 1.4 times as high for males (100 compared with 72 per 100,000) (Figure 3).
  • 1.7 times as high in the lowest socioeconomic group compared with the highest socioeconomic group (73 compared with 43 per 100,000, in 2015). This gap was similar for males and females (Figure 3).
  • Overall 4 times as high among Indigenous Australians compared with their non-Indigenous counterparts (209 and 55 deaths per 100,000, respectively, in 2013–2015). This disparity was higher for females than males―5 times as high for females (217 compared with 43 per 100,000) and 2.8 times as high for males (198 compared with 71 per 100,000) (Figure 3).

Figure 3: CKD deaths (underlying and/or associated cause), by selected population characteristics, 2013–2015

The horizontal bar chart shows that in 2013–15, CKD death rates (as an underlying and/or associated cause) in Remote/Very remote areas compared with Major cities were 2.3 times as high for females and 1.4 times as high for males. Similarly, rates in the lowest socioeconomic group (group 1) compared to the highest socioeconomic group (group 5) were 1.7 times as high for females and 1.5 times as high for males. CKD death rates for Indigenous females were 5 times as high & Indigenous males 2.7 times as high as their non-Indigenous counterparts.
