What to Look For
Key factors when choosing a dialysis center in California
Quality Rating
CMS rates dialysis facilities 1-5 stars based on patient outcomes including mortality, hospitalization, and readmission rates. Choose centers with 4+ stars when available.
Treatment Options
Verify the center offers your preferred modality — in-center hemodialysis, peritoneal dialysis, home hemodialysis training, or nocturnal dialysis for overnight treatment.
Infection Control
Review bloodstream infection rates and vascular access quality metrics. Lower infection rates indicate better hygiene practices and patient safety protocols.
Schedule & Convenience
Since dialysis is typically needed 3 times per week, consider location, available treatment times (including early morning, evening, or weekend shifts), and transportation options.
Clinical Outcomes
Compare standardized mortality ratios, hospitalization rates, and transplant waitlist referral rates. Facilities performing above national benchmarks deliver meaningfully better care.
