Abstract
Background:
Albumin has been shown to decrease the incidence of mortality and acute kidney injury (AKI) in patients with spontaneous bacterial peritonitis (SBP). Albumin administration in SBP is recommended within 6 hours of diagnosis and for reserved use in high-risk patients with the following baseline laboratory tests: serum creatinine >1 mg/dL, blood urea nitrogen >30 mg/dL or total bilirubin >4 mg/dL.
Objective:
We aimed to assess the impact of an albumin order set restricted to high-risk SBP.
Methods:
A retrospective cohort study was conducted between Jan 1, 2013 to Feb 28, 2018. The albumin order set was implemented on Sep 20, 2016. Patients were included if they were diagnosed with SBP and had an ascitic fluid polymorphonuclear count ≥ 250 cells/mm3.
Results:
Out of a total of 137 patients reviewed, 88 met the inclusion criteria. The incidence of AKI in the pre-order set and post-order set were 63.93% and 33.33% (p = 0.01), respectively. The incidence of mortality in the pre-order set and post-order set were 36.07% and 7.41% (p = 0.005), respectively. The percentage of patients administered albumin within 6 hours were 24.59% to 40.74% (p = 0.14) in the pre-order set and post-order set, respectively. The percentage of patients who received the recommended albumin dosing regimen ordered was 42.62% vs 96.30% (p < 0.001), in the pre-order set and post-order set, respectively.
Conclusion:
The albumin order set restricted to high-risk SBP patients significantly reduced the incidence of AKI and mortality, and improved the appropriateness of albumin regimen ordered.
