Association of early red blood cell distribution width with initiation of continuous renal replacement therapy in patients with sepsis
To investigate the association between red blood cell distribution width (RDW) and initiation of continuous renal replacement therapy(CRRT) in patients with sepsis.
Methods
2
A total of 17 216 patients who met the Sepsis-3 criteria were included based on Medical Information Mart for Intensive Care-Ⅳ 3.0,and RDW was categorized into quartiles(Q1,Q2,Q3,and Q4). A binary logistic regression analysis was used to investigate the influence of RDW on CRRT initiation; subgroup analyses and the receiver operating characteristic(ROC) curves were used to evaluate the predictive performance of RDW across different populations; the restricted cubic spline(RCS) analysis was used to determine the threshold of RDW.
Results
2
The initiation rate of CRRT increased significantly with increase in RDW(
χ
²=425.978,
P
<
0.001),and the initiation rates of CRRT were 2.0%,3.3%,5.7%,and 11.5%,respectively,in groups Q1,Q2,Q3,and Q4. The logistic trend analysis showed an increasing trend in the association between RDW and CRRT initiation(
P
=0.007),and compared with group Q4,groups Q1,Q2,and Q3 had an odds ratio(
OR
) of 0.60 (95%CI=0.43-0.84),0.69(95%CI=0.52-0.90),and 0.78(95%CI=0.62-0.98),respectively. Subgroup analyses demonstrated significant interactions between RDW and age,hypertension status, cirrhosis status, heart failure status, and septic shock status(
P
<
0.05). The ROC curve analysis showed that RDW had a larger area under the ROC curve(AUC) in the patients aged
<
65 years(AUC=0.73,95%CI=0.72-0.74,
P
<
0.05),those without heart failure(AUC=0.73,95%CI=0.72-0.74,
P
<
0.05),and those without septic shock(AUC=0.70,95%CI=0.69-0.71,
P
<
0.05). The RCS analysis showed a non-linear relationship between RDW and CRRT initiation(
P
nonlinear
<
0.001),and when RDW exceeded 14.25%,there was a significant increase in the risk of initiating CRRT(
OR
>
1,
P
<
0.001).
Conclusion
2
RDW is an important risk factor for initiating CRRT in patients with sepsis,and it has a higher application value in the patients aged <65 years and those without heart failure or septic shock and can assist physicians in the stratification of the population at a high risk of CRRT.
