About

Anemia affects the quality of life of CKD patients and increases the risk of CKD progression. we conducted a real-world study on patients with anemia in CKD to analyze the disease characteristics and treatment in Chinese patients with CKD-anemia.

Full description

Anemia adversely affects the quality of life of CKD patients and increases the risk of CKD progression.

This study utilize data from approximately 20 medical centers across China. It aims to:

1. Analyze the disease characteristics, current diagnostic and treatments in Chinese patients with CKD-anemia.
2. Evaluate the safety and efficacy profiles of different drugs used for CKD-anemia.
3. Explore the direct medical costs associated with CKD-anemia management within real-world clinical practice in China.

Enrollment: 20,000 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

2. record of hemodialysis (HD) or peritoneal dialysis (PD) (refer to Attachment 2 for dialysis identification algorithms)
3. ≥2 eGFR measurements <60 mL/min/1.73m² (calculated using CKD-EPI equation) with ≥3-month interval (excluding acute kidney injury)
