CCHT case studies

CCHT · Put your knowledge to work in context.

The Certified Clinical Hemodialysis Technician (CCHT) credential is a nephrology-specific certification from the Nephrology Nursing Certification Commission (NNCC), designed for practicing dialysis technicians who hold a high school diploma or a GED. It signals that a technician has met a national practice standard in hemodialysis care, and NNCC frames its certification programs around patient safety and quality of care rather than generalist testing. The CCHT case studies are 5 cases and about 3,497 words.
