Abstract:

Objective

To evaluate the prognostic value of baseline SOFA coagulation score (SOFA-CS) in patients with septic acute kidney injury (S-AKI) requiring continuous renal replacement therapy (CRRT).

Methods

This retrospective study included 180 patients with S-AKI receiving CRRT from January 2017 to October 2020 in the Department of Critical Care Medicine of Beijing Friendship Hospital affiliated to Capital Medical University. Patients were divided into normal SOFA-CS group (SOFA-CS=0) and abnormal SOFA-CS group (SOFA-CS≥1). The primary outcome was all-cause mortality at 60 days after initiation of CRRT. The association between baseline SOFA-CS, process of care, and clinical outcomes were analysed using multivariate Cox model adjusted for baseline variables.

Results

Among 180 S-AKI patients, 66 patients had normal SOFA-CS at baseline, while 114 patients had an abnormal SOFA-CS. The 60-day mortality rate in abnormal SOFA-CS group was higher than that in normal SOFA-CS group (45.5% vs 64.0%, P=0.015). There was no significant difference in the length of ICU stay (P=0.870) and duration of CRRT (P=0.270) between two groups. Multivariable Cox regression analysis showed that an abnormal SOFA-CS was independently associated with an increased risk of death at 60 days (HR=1.616, P=0.034).

Conclusion

Abnormal coagulation is a common phenomenon in patients with S-AKI receiving CRRT. An abnormal baseline SOFA coagulation score is associated with increased mortality at 60 days.
