Comparison of hospitalization cause and risk factors between patients undergoing hemodialysis and peritoneal dialysis

This retrospective study was designed to compare the cause of hospitalization and influencing factors between patients undergoing hemodialysis (HD) and peritoneal dialysis (PD). Baseline data and laboratory parameters of 192 dialysis patients (92 HD patients and 100 PD patients) were compared. Quantitative parameters with normal distribution were assessed using independent t-test or analysis of variance (ANOVA). Quantitative parameters with non-normal distribution were assessed by non-parametric test. Qualitative data were statistically compared using χ(2) test. The number of patients with urban employee medical insurance (88 HD patients and 60 PD patients) and rural cooperative medical care (12 HD patients and 40 PD patients) significantly differed (P < .01). The hospitalization rate of PD patients was significantly higher than that of HD counterparts. The average length of hospital stay of PD patients was 10 days, remarkably longer than 8 days of HD patients (P < .01). The primary cause of hospitalization for HD patients was infection-related complications, followed by cardiovascular, cerebrovascular complications and dialysis access disorders. The primary cause of hospitalization for PD patients was infection-related complications, followed by dialysis access disorders, cardiovascular, and gastrointestinal complications. Compared with the HD group, the levels of hemoglobin, serum albumin, alkaline phosphatase, intact parathyroid hormone were significantly decreased, whereas serum urea nitrogen, serum creatinine, phosphorus levels and cardiothoracic ratio were remarkably increased in the PD group (all P < .01). The hospitalization rate of PD patients is relatively higher, and the length of hospital stay is longer. Extensive attention and efforts should be delivered to enhance the understanding of disease and lower the risk of complications for patients.
