A pragmatic randomized controlled trial comparing pathway-based versus usual care in community-acquired acute kidney injury

Clinical pathways have shown conflicting evidence in improvement of several patient-centered outcomes across different clinical settings. However, the effectiveness of clinical pathway in management of acute kidney injury (AKI) has not been reported. Therefore, we aimed to assess the length of hospital stay (LOS) and patient-centered outcomes in community acquired AKI and compared pathway care (PC) versus usual care (UC). The CHAMP-Path AKI Trial is a pragmatic, parallel, single-blind randomized controlled trial. Physicians were randomized to provide either UC or PC. Patients were randomized through a computer-generated sequence. Allocation was concealed. Patients presenting to the emergency department with AKI and hemodynamic stability, who were over 14 years with a serum creatinine greater than 1.5 times the baseline were eligible. Patients with chronic kidney disease stages 4 or 5, kidney transplantation recipients, those admitted with obstructive uropathy, suspected glomerular or interstitial disease, and pregnant women were excluded. Thirty-eight patients were enrolled from March 2012 to December 2013. The primary outcome was LOS. Secondary outcomes included: 30-day re- admission, in-hospital respectively (P = 0.770). Of the five readmissions, none were for AKI. No in-hospital mortality was reported. The CHAMP-Path AKI pragmatic trial demonstrated that PC was not different than UC in reducing LOS. There was no difference in 30-day readmission, in-hospital mortality, and patient-centered outcomes.
