Who is a Certified Bariatric Nurse (CBN)?

A Certified Bariatric Nurse (CBN) is an RN who also holds a certificate from ASMBS’ Certified Bariatric Nurse program indicating achievement of the specialized skills and knowledge required for the delivery of quality patient care for the morbidly obese and bariatric surgery patients. CBN candidates must hold an RN license (or an international equivalent), have two years of experience in caring for morbidly obese and bariatric surgery patients and pass the CBN examination. When all of these criteria have been met, candidates are free to use the CBN designation after their name. The CBN credential is issued for a term of 4 years, at which time a CBN may re-certify to maintain the certificate.
