(HealthDay News) — Patients with an emergency department discharge with acute kidney injury have increased mortality compared to those with no acute kidney injury, according to a study published online in the Clinical Journal of the American Society of Nephrology.
Rey R. Acedillo, MD, from the London Health Sciences Center in Canada, and colleagues conducted a population-based retrospective cohort study of 6346 patients aged 40 years or older discharged from the emergency department with acute kidney injury. Propensity score methods were used to compare all-cause mortality with two referent groups. A total of 4379 discharged patients were matched with 4379 patients hospitalized from the emergency department with similar stage of acute kidney injury; 6188 discharged patients were matched to 6188 patients discharged home from the emergency department with no acute kidney injury.
The researchers found that there was lower mortality for an emergency department discharge vs hospitalization with acute kidney injury (3% vs 12%; relative risk, 0.3). Higher mortality was seen in association with an emergency department discharge with acute kidney injury vs no acute kidney injury (2% vs 1%; relative risk, 1.6).
“Patients discharged home from the emergency department with acute kidney injury are at risk of poor 30-day outcomes,” the authors write. “A better understanding of care in this at-risk population is warranted, as is testing strategies to improve care.”
