History and evolution of a successful certification program in nutrition support: the CNSD experience

Abstract

As early as the 1970s, articles were published on the role of dietitians in nutrition support. Both the American Society for Parenteral and Enteral Nutrition and The American Dietetic Association addressed the issues of specialization and certification. Development of a specialty area credential requires a strong demand by practicing clinicians, a unique area of clinical practice with a distinct body of knowledge and the commitment to evolve with clinical practice. Numerous dietitians were involved in the inception, development, and leadership that brought forth certification in nutrition support. This article documents the efforts and participation of a dedicated group of professionals whose common goals resulted in the establishment of a successful, sustaining certification in a specialty area of clinical dietetics: certified nutrition support dietitian. The certified nutrition support dietitian program is now in its 15th year with 2,000 dietitians currently certified both nationally and internationally. A primary focus of the credential is to recognize minimum competency for dietitians practicing in the field of enteral and parenteral nutrition and to provide safe and effective nutrition support therapy. This article provides a framework for persons in other specialty areas attempting to develop certification programs.
