Acute renal failure (ARF) is increasingly common, affecting more men and the elderly. New methods using serum creatinine reveal higher incidence rates than previously thought.
Area of Science:
- Nephrology
- Public Health
- Epidemiology
Background:
- Limited data exists on the true incidence of acute renal failure (ARF) in the general population.
- Hospital-based studies are confounded by varying thresholds and hospitalization rates.
- Previous reliance on low-sensitivity diagnostic codes underestimated ARF incidence.
Purpose of the Study:
- To quantify the incidence of non-dialysis and dialysis-requiring ARF.
- To utilize serum creatinine changes for more accurate ARF case identification.
- To assess trends in ARF incidence within a large integrated healthcare system.
Main Methods:
- Analysis of electronic health records from Kaiser Permanente of Northern California (1996-2003).
- Identification of non-dialysis ARF using inpatient serum creatinine level changes.
- Identification of dialysis-requiring ARF through medical records.
Main Results:
- Incidence of non-dialysis ARF increased from 322.7 to 522.4 per 100,000 person-years.
- Incidence of dialysis-requiring ARF increased from 19.5 to 29.5 per 100,000 person-years.
- ARF was more prevalent in men and the elderly; older adults (≥80 years) received dialysis less frequently.
Conclusions:
- Serum creatinine measurements provide higher estimates of non-dialysis ARF incidence than prior methods.
- Both dialysis-requiring and non-dialysis ARF are becoming more common.
- The rising incidence of ARF highlights its significant public health importance.

Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
