SEVERITY AND MORTALITY OF PATIENTS UNDERGOING CONTINUOUS HAEMODIAFILTRATION IN THE ICU

Abstract

Introduction: Regardless of the primary disease, acute kidney injury  (AKI) is an additional aggravating factor that increases hospital mortality and severity. .It has been estimated that   the overall incidence of AKI in ICU patients undergoing mechanical ventilation ranges from  5% to 35% with a mortality rate that exceeds 20%

Aim:  The purpose of the present study is to estimate the severity and mortality of patients undergoing continuous hemodialysis (CVVHDF) in the ICU of a Public Hospital in Athens.

Material and Methods: The study is a descriptive analysis of all patients receiving CVVHDF in the ICU between April 2017 and December 2017. Demographic data such as age gender admission diagnosis, length of stay  and outcome were recorded. The duration of each   CVVHDF session as well as specific clinical data relating to the treatment of renal replacement therapy were   also recoded

Results: The sample size was   33 patients (32.3%)   received   continuous hemodiafiltration   (CVVHDF) over the study period. The median age of the sample was 72.7 ± 9.46 years. The median length of stay was 16.5 days (1-91 days) while mean APACHE II of patients was 28.5 ± 9.08. The mortality rate in the studied sample was   60.6%

Conclusions: The  cost of the method as well as the high percentage of patients' mortality make  necessary to establish clear criteria for the application of the method, continuous assessment and evaluation of its effectiveness, as well as continuous training of medical and nursing staff in the use of such technologies.
