A survey of credentialing practices of gastrointestinal endoscopy centers in the United States.

BACKGROUND: Competence in gastrointestinal (GI) endoscopy correlates with the number of procedures performed by the endoscopist. For each GI endoscopic procedure, the American Society for Gastrointestinal Endoscopy (ASGE) guidelines recommend minimum numbers needed to assess competence.
METHODS: We conducted an anonymous mail survey to determine whether GI endoscopy centers in the United States follow ASGE or other guidelines for granting and renewing endoscopic privileges.
RESULTS: Completed surveys were received from 479 respondents in 46 states, Puerto Rico, and the District of Columbia. Most respondents were either the physician director (24%) or nurse manager (57%) of the endoscopy center. Most centers have more than 5 endoscopists (62%), and gastroenterologists performed procedures in the majority of the centers (89%). For initial endoscopic credentialing, few centers require a minimum number of procedures and only 10% meet ASGE criteria. To maintain credentials, less than one third require a minimum number and only 2% require more than 25 procedures/year. Although three fourths report periodic review of procedures, less than 5% review them more frequently than every 6 months. Only 20% of centers had ever denied endoscopic privileges (poor skills [80%], no references [27%], poor communication [7%], and excess complications [6%]) for which half faced litigation.
CONCLUSIONS: Most GI endoscopy centers responding to this survey have no minimum standards for determining endoscopic competence and may credential GI endoscopists with suboptimal training. Only 10% adhere to ASGE guidelines. Moreover, there is lack of uniformity to application of these guidelines, and few centers use resulting data to deny or renew credentials. To guarantee high-quality endoscopic practice, more stringent, universal credentialing standards are required.
