This pilot study on elderly patients found pre-renal failure, common in 55% of cases, had a good prognosis. Intrinsic renal disease affected 35% with a 48% mortality rate.

Area of Science:

  • Geriatrics
  • Nephrology
  • Internal Medicine

Background:

  • Renal failure is a significant concern in elderly patients.
  • Understanding the causes and outcomes of renal failure in this demographic is crucial for effective management.

Purpose of the Study:

  • To investigate the incidence, management, and outcomes of renal failure in elderly patients admitted to geriatric units.
  • To differentiate between pre-renal and intrinsic renal causes of failure and assess their respective prognoses.

Main Methods:

  • A pilot study conducted over six months in three geriatric units.
  • Inclusion criteria for renal failure: plasma urea ≥ 17 mmol/l and/or creatinine ≥ 160 µmol/l.
  • Analysis of patient demographics, cause of renal failure, treatment, and outcomes.

Main Results:

  • 273 out of 4001 admitted patients presented with renal failure.
  • Pre-renal causes accounted for 55% of cases with a >60% recovery rate, unaffected by age.
  • Intrinsic renal disease occurred in 35% of patients, was more common in younger individuals, and had a 48% mortality rate.
  • The majority of renal failure cases were mild.

Conclusions:

  • Pre-renal acute kidney injury in the elderly has a favorable prognosis.
  • Intrinsic renal disease presents a higher mortality risk in elderly patients.
  • Early identification and management strategies are essential for improving outcomes in geriatric renal failure.
