The Effect of Treatment on Short-Term Outcomes in Elderly Patients with Acute Kidney Injury.

BACKGROUND

Elderly population (≥ 65) are more prone to develop acute kidney injury (AKI) compared to younger, also elderly with AKI have an increased requirement for dialysis treatment and an elevated risk of short-term and long-term mortality.

AIM

The objectives of this study were to examine the effect of treatment of short-term outcomes and mortality in elderly patients with AKI.

MATERIAL AND METHODS

Seventy elderly AKI patients, that filled one of the criteria of AKI definition and had hospitalization over 24 hours, were enrolled in the study.

RESULTS

The median age of patients was 74.28 ± 6.64, with mean CCI (Charlson Comorbidity Index) score of 6.94 ± 1.94. The majority of patients (70%) were classified at stage 3 of AKIN, 20% of patients were classified at stage 2 and 10% at stage 1. In the groups of patients with death outcome, the chronic cardiomyopathy was more frequently present (p = 0.034). Regarding treatment, 58.6% of the AKI patients underwent hemodialysis while 41.4% received conservative treatment. Mortality rate was 52.8%, out of which 28.6% was in-hospital mortality, while in 24.3% of patients death occurred in the follow-up period of 90 days.

CONCLUSION

In our study, short- term survival is not related to different treatment options. Applied treatment in elderly patients with AKI should be assessed by measuring the long term outcome.
