Background

Assess risk factors for early death in patients who underwent urgent-start peritoneal dialysis (USPD).

Methods

Patients who initiated USPD in five peritoneal dialysis (PD) centers from 2013 to 2019 were screened in this multicenter retrospective cohort study. Risk factors for all-cause mortality within 3 months were explored.

Results

A total of 1265 USPD patients with 43 early deaths were included. Cox regression analyses showed that age older than 60 years (HR, 3.054; 95% CI, 1.597-5.842; P=0.001), albumin less than 30 g/L (HR, 2.234; 95%CI, 1.207-4.136; P=0.011), blood glucose greater than 7 mmol/L (HR, 2.766; 95%CI, 1.477-5.180; P=0.001), higher estimated glomerular filtration rate (eGFR, HR, 1.121; 95%CI, 1.071-1.172; P=0.000), and poor stages of heart failure (class IV compared with class 0-I, HR, 5.165; 95%CI, 2.544-10.486; P=0.000) were independent predicting factors for early death.

Conclusions

Risk factors for early death were older age, hypoproteinemia, hyperglycemia, higher eGFR, and sever heart failure.
