Acute renal failure in the State of Qatar: presentation and outcome

Despite major improvements in health care, acute renal failure is still one of the main prognostic factors in terms of patient mortality and long-term morbidity. This cohort prospective study to evaluate the patterns and outcomes of renal failure in Qatar was performed between January and June 2005. Of the 213 patients followed prospectively from referral to the end of their hospitalization, 66.7% were males and 33.3% females. Their overall mean age was 60 years; the majority were referred from critical care units. Comorbidity was present in 87% of all patients. Volume depletion, hypotension, and sepsis were the main predisposing factors for renal failure. Eighty three patients (39%) needed renal replacement treatment and 130 (61%) were treated conservatively. The majority of critical care patients needed dialysis. Overall mortality was 23.9%, 7% needed chronic dialysis, and 69.1% were discharged with normal or mild renal impairment. This study showed that acute renal failure was a major factor affecting patient mortality in Qatar. Early treatment of predisposing factors may improve overall patient outcomes.
