From the Guidelines
A trained Nurse Practitioner (NP) should not interpret small bowel capsule studies independently, as the current guidelines recommend that capsule endoscopy be performed and interpreted by a gastroenterologist experienced in conducting, interpreting, and reporting capsule endoscopy procedures. According to the ECCO-ESGAR guideline for diagnostic assessment in IBD part 2 1, capsule endoscopy in IBD patients should be evaluated by gastroenterologists with experience in conventional endoscopy in IBD patients. While NPs can develop competency in interpreting small bowel capsule studies with specialized training, the guideline emphasizes the importance of gastroenterologists' expertise in this area.
Some key points to consider:
- The ECCO-ESGAR guideline 1 highlights the need for gastroenterologists to interpret capsule endoscopy procedures, particularly in IBD patients.
- NPs may require formal training programs, mentorship from experienced gastroenterologists, and verification of their state's scope of practice regulations and institutional credentialing requirements to develop competency in interpreting small bowel capsule studies.
- Complex cases or findings requiring advanced intervention should typically involve consultation with a gastroenterologist, as they have the necessary expertise and experience in conventional endoscopy and capsule endoscopy procedures 1.
In real-life clinical practice, it is essential to prioritize patient safety and adhere to established guidelines, which recommend that gastroenterologists interpret small bowel capsule studies. Therefore, trained NPs should not interpret these studies independently, but rather work under the supervision of experienced gastroenterologists to ensure optimal patient care.
From the Research
Scope of Practice for Nurse Practitioners
- The scope of practice for Nurse Practitioners (NPs) varies by jurisdiction and employer, but generally includes assessing patients, ordering diagnostic tests, and interpreting results 2, 3.
- However, the specific question of whether a trained NP can interpret small bowel capsule studies is not directly addressed in the provided evidence.
Interpretation of Small Bowel Capsule Studies
- Small bowel capsule endoscopy is a specialized procedure that requires formal training and competency assessment to interpret accurately 2, 4.
- Studies have shown that gastroenterology fellows require a minimum of 20 capsule endoscopy interpretations to achieve competency, regardless of previous endoscopy experience 5.
- The use of deep-learning models has been explored to assist in the evaluation of small bowel capsule endoscopy images, with high sensitivity and shorter reading times compared to conventional analysis by gastroenterologists 6.
Implications for Nurse Practitioners
- While NPs may have the scope of practice to order diagnostic tests, including small bowel capsule endoscopy, the interpretation of these studies typically requires specialized training and expertise.
- There is no direct evidence to suggest that trained NPs can interpret small bowel capsule studies, and it is likely that this task would require additional education and training beyond the typical NP scope of practice 2, 3, 4, 5, 6.
