Abstract

BACKGROUND:

Acute kidney injury is a common disorder in critical ill patients and it is associated with high mortality. Few studies focus on long-term perspectives such as health-related quality of life (HRQOL) and dialysis dependence.

METHODS:

Prospective cohort study at the intensive care unit (ICU) of a Brazilian tertiary hospital. All patients requiring dialysis over a 2-year enrollment period were included. The Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) assessed the HRQOL along with patient status and dialysis dependence.

RESULTS:

408 patients (11%) required dialysis. ICU, hospital, and after-hospital cumulative fatality rates were 70%, 74%, and 80%, respectively. A total of 68 of 82 eligible patients were interviewed in an average of 256 days after hospital discharge, while 8 patients (11.8%) were in regular dialysis. There was no association between Acute Physiology and Chronic Health Evaluation II score, use of vasopressors, mechanical ventilation, creatinine, number of dialysis, and SF-36 scores. Better HRQOL was associated with previous conditions, as younger age and no chronic kidney disease; condition related to severity of acute illness, as have not had sepsis, short period at ICU, and hospital; and conditions after discharge, considered working currently.

CONCLUSIONS:

Previous chronic kidney disease was strongly associated with permanence in dialysis and lower further HRQOL. Younger survivors who have not had sepsis or long stays at hospitals, able to return to their jobs, had better HRQOL.
