RESUMEN
As a home treatment and economical and practical treatment mode, peritoneal dialysis (PD) is an effective renal replacement therapy for end-stage kidney disease. The number of PD patients in the world is increasing, and prognosis has been significantly improved. However, compared with the general population, the quality of life of PD patients is not satisfactory, and the disease burden is still very high. There is significant heterogeneity in the reports of clinical outcomes of PD in different countries and regions. The heterogeneity seriously affects the validity of clinical research evidence and the continuous improvement of the quality of PD centers. New progress has been made in the study of standardized clinical outcome of PD in recent years. The article reviews the heterogeneity of PD clinical outcome report, standardized clinical outcome classification and core outcome to standardize the report of PD clinical outcome, improve the clinical research quality and management level of PD, and finally improve the prognosis of patients.
