Developing a career in nutrition support and small-bowel disorders
The role of diet and nutrition is becoming increasingly recognized in the cause, management, and prevention of disease. Despite the clear importance of the role of nutrition in the field of medicine, among health professionals, formal training in nutrition support is lacking. A lack of nutrition training has been recognized in multiple subspecialty fields1 and is highlighted by a shortage of physicians trained to manage disease-related malnutrition.2 Gastroenterologists, in particular, have a special responsibility related to nutrition in disorders of the gastrointestinal tract and are in a unique position to recognize and manage disorders of maldigestion and malabsorption. Unfortunately, surveys of both U.S. and Canadian fellows have demonstrated deficiencies in the training of nutrition support and management of enteral and parenteral nutrition (PN).3,4
Current status of nutrition training
The impact of diet and nutrition on health and disease is universally recognized but unfortunately lagging with respect to formal training at all levels of medical education. A survey of program directors from primary care, surgery, and anesthesia showed only 26% of respondent programs had a formal curriculum in nutrition education.1 Specific to gastroenterology, a majority of trainees and recent graduates perceived that nutrition education was an important aspect of their training; however, only 50% of respondents had training in nutrition support with 36% reporting mandatory training.3
The Gastroenterology Core Curriculum, most recently updated in 2007 – and sponsored by the American Association for the Study of Liver Diseases, American College of Gastroenterology, the American Society for Gastrointestinal Endoscopy, and the American Gastroenterological Association – includes six domains of nutrition training within the training track: nutrition assessment, basic nutrition requirements, specific gastrointestinal disorders and other allied diseases, enteral nutrition, PN, and diet therapy. Level 1 training is expected for all gastroenterology fellows. Level 2 is comprised, on average, of an additional 12 months with described objectives, either occurring outside of a standard gastroenterology fellowship or coinciding with a dedicated third year of training. Although training durations for level 1 are not defined, level 2 recommends at least 6 months of experience working with an inpatient nutrition support team (NST) and the management of outpatients in nutrition and weight management clinics.5
Role of a nutrition support team
Training in nutrition is a heterogeneous field, with a wide range that covers understanding metabolism in health and disease, micronutrient and macronutrient requirements, nutrient digestion and absorption, and the best route and provision of nutrition support. Therefore, a critical aspect of education includes access to a dedicated NST. Such teams were common and necessary in the late 1900s with the inception of specialized nutrition therapy. However, with an increase in the use of home infusion therapies, NSTs were dismantled in favor of shifting responsibility to decentralized home infusion companies. A dedicated NST often will include some combination of pharmacists with an interest in the safe compounding of parenteral formulas, nurses with experience in the home management of intravenous therapies and catheters, and dietitians with dedicated interests in intestinal failure, recognition of malnutrition, and provision of calories. Collectively, a highly functioning NST also provides dedicated multidisciplinary training to health professionals of varying backgrounds.
My entry into the field of nutrition support
Entering a fellowship in gastroenterology should be pursued with an open mind. We all have varying experiences in the management of patients with gastrointestinal conditions, both in the inpatient and outpatient arenas through residency training. My early experiences in fellowship at the University of Chicago centered on the management of patients with inflammatory bowel disease (IBD) and with research interests related to the clinical course of IBD. I was also fortunate to be part of a fellowship program offering both level 1 and level 2 training with a longstanding track record of graduating fellows responsible for the running of NSTs at their local institutions. Categorical fellows spend 3 months of training on a rotation with combined inpatient and outpatient responsibilities focusing on the management of patients with intestinal failure, inpatient management of complications from PN support, and an outpatient clinic focused on small-bowel disorders (celiac disease, small-bowel bleeding, and intestinal malabsorption). This experience led me to pursue level 2 training at Northwestern University with a combined focus on small-bowel diseases and enteroscopy.
These collective experiences in fellowship and postfellowship training grounded my ideas on the role of nutrition pervading many gastrointestinal conditions from acute and chronic pancreatitis and IBD to rare conditions such as enteropathy associated with immune deficiencies and autoimmune enteropathy. Now, as a junior faculty member with a focus in nutrition support and small-bowel disorders, my clinical responsibilities include a dedicated half-day in the management of outpatients (parenteral and enteral nutrition), inpatient rounding with our dedicated NST focusing on the initiation of PN, management of home PN complications, and dedicated procedural time focusing on enteral access techniques (percutaneous gastrostomy/jejunostomy tubes) and small-bowel enteroscopy. To my surprise, entry into the field of nutrition support and small-bowel disorders has been filled with excitement and a growing list of collaborations and opportunities. While initial work in the management of PN has been in existence since the 1970s and earlier with respect to the development of safe administration techniques, most of my current work transcends specialties as we develop appropriateness criteria related to PN support in collaboration with a wide range of specialties that include surgery, oncology, and palliative care.
Seeking opportunities for additional training
As the field of gastroenterology grows outward in various directions, mastery of subjects has led to subspecialization in specific areas including interventional gastroenterology, pancreatology, IBD, and motility disorders. The field is primed for broader access to specialty training in nutrition support and small-bowel disorders. Exposure to dedicated training in nutrition and nutrition-related disorders is vital as part of a categorical fellowship, but can also be complemented via visiting observerships, access to formal level 2 training programs, and external programs related to promoting nutrition education.
Since 2001, formal nutrition fellowship programs offering level 2 training have been compiled by the National Board of Physician Nutrition Specialists, although attraction of interested fellows has been lacking.2 The Nestlé Nutrition Institute Clinical Nutrition Fellowship, endorsed by the American Society for Parenteral and Enteral Nutrition and the AGA, is an ongoing program that pairs interested trainees with expert program faculty through onsite clinical rotations lasting a total of 4 weeks.2 Attendance at national and international conferences can supplement a fellows training in nutrition, and an increased focus on nutrition lectures should be a priority of meeting education committees to increase the exposure of trainees to leaders in the field.
Conclusion
A career in nutrition support and small-bowel disorders is incredibly rewarding as it incorporates the basic physiologic processes of digestion and absorption with a wide array of pathologic conditions. Incorporation of the basic principles of intestinal absorption allows for a greater understanding of the role of the low–fermentable oligo-, di-, monosaccharides and polyols (FODMAP) diet in the management of irritable bowel syndrome to the varying principles of diets currently under study for the management of IBD. Outside of this spectrum, working with an NST allows for the management of complex cases of malnutrition resulting from disorders ranging from cancer to various postsurgical intestinal alterations. Although observerships and external training programs allow for an introduction into the field, formal level 2 training, combining both work with a NST and small-bowel enteroscopy, allows for exposure to the full range of disorders of the small bowel. As patients continue to seek disease management options rooted in diet, the demand for gastroenterologists with subspecialty training in nutritional disorders will continue to grow and will require further support across training programs to incorporate additional training into categorical fellowships.
