Abstract: 【Abstract】Objective To investigate the survival status within one year and the factors that affect the prognosis in patients on peritoneal dialysis (PD). Methods In this retrospective cohort study, patients who started PD during Jan. 1, 2006 to Dec. 31, 2014 were included. Cox regression model was used to estimate the factors that affect early survival of the patients. Results We recruited 608 patients, in which 63 patients died within one year and 545 patients rmained alive. Cox regression analysis showed that age (HR 1.047, 95% Cl 1.024～1.071, P＜0.001), hypoalbuminemia (HR 0.900, 95% Cl 0.854～0.949, P＜0.001), urine volume (HR 0.999, 95% Cl 0.998～1.000, P=0.003), bedridden (HR 2.112, 95% Cl 1.148-3.885, P=0.016) and amputation history (HR 10.927, 95% CI 1.407～84.846, P=0.022) were associated with higher mortality rate, and regular clinic visit pre-dialysis (HR 0.422, 95% Cl 0.242～0.737, P=0.002) was associated with lower mortality rate. Conclusions Regular clinic visit pre-dialysis was associated with better outcome. Patients with advanced age, bedridden status, amputation history, hypoalbuminemia and oliguria were associated with poor outcomes
