There is increasing interest and literature on improving and measuring the quality of endoscopy performance. We present the results of a workshop designed to define quality metrics that can be used now. Collection of structured data on a voluntary basis will stimulate improvement in endoscopic training, practice, and credentialing. Patients and practitioners will benefit. It is the right thing to do. Over the last 4 decades, digestive endoscopy has evolved from an occasional diversion for a few enthusiasts into a fundamental tool of gastroenterology. Endoscopy has become enormously popular throughout the world because of its tremendous and proven value in diagnosis and treatment. The problem is that the benefits are maximized only when procedures are performed at an optimal level of quality, which is not always the case. Technical failures and serious complications can occur in the best of hands but are more likely when procedures are performed by endoscopists with inadequate training and experience. Practitioners, patients, and payers should all be interested in enhancing the quality of endoscopic services. The professional organizations associated with endoscopy and their leaders have increasingly embraced the quality improvement paradigm that is advancing through medicine, as it has through manufacturing industry.1-4 The American Society for Gastrointestinal Endoscopy (ASGE), and the American College of Gastroenterology particularly have produced helpful reports and guidelines.5,6 In Britain, the Joint Advisory Group that represents all of the interested parties7 has been active in this area, as have other organizations around the world. The problem is that these thoughtful conclusions and well-meaning documents have had little impact so far in the real world. Quality is discussed but is not measured to any extent. Seldom do hospital privileging bodies follow published guidelines for credentialing, which include the use of proctored evaluation in some circumstances.8 We need to agree on what constitutes ‘‘excellence’’ and then develop appropriate metrics and systems to collect
the data. This will bring objectivity to training and will stimulate improvements in practice. Patients will benefit. These considerations led to the development of a study meeting entitled ‘‘Excellence in Endoscopy,’’ which was held in Albuquerque, New Mexico in October 2004.
Measuring and improving the quality of endoscopic performance will undoubtedly benefit patients and practitioners. It is the right thing to do.
METHODS Twenty leading North American gastroenterologists and selected guests were invited to consider 3 related topics. 1. What are the metrics of excellence in endoscopy? 2. How can the data be collected, analyzed, and used? 3. How can excellence be trained and enhanced? There were 3 team leaders, Robert Hawes, Alan Barkun, and Gregory Ginsberg. Each selected a team of 6 to 8 participants about 6 months before the meeting to focus on specific aspects of their allocated topic. They were tasked to review the relevant literature, circulate drafts, and then to present their recommendations in plenary session at the meeting, which lasted 2 days. After the workshop, the team submitted updated recommendations for inclusion in the final document. This report covers the first section of the meeting, i.e., developing the metrics of endoscopic excellence. Reports of the other sections will follow. The meeting was supported by Olympus America Inc., Medical Systems Group, Melville, NY.

performed expeditiously, skillfully, successfully, safely, and comfortably.9 These expectations can be expanded to make a list of desirable characteristics for all types of endoscopic procedures. These include cognitive and technical skills of endoscopists but also appropriate behavior, environment, and staff. Elements of good endoscopy performance include the following: d Correct indications, adherence to published guidelines d Appropriate environment, support team, and behavior d Well prepared and informed patients d Strategies to minimize risk, including patient preparation and monitoring d Appropriate use of medications, including sedation/ analgesia when used d Correct selection of equipment d Comfortable intubation d Complete survey of the target organ(s) d Recognition of all abnormalities (and photographic documentation) d Appropriate tissue sampling (adherence to published guidelines) d Application of indicated therapy d Avoiding, recognizing, and managing complications d Reasonable duration d Smooth recovery, explanation, and discharge d Detailed and clear recommendations and follow-up plans d Integrated pathology results and communications d Complete documentation (and billing) d Positive feedback from patients Some of these elements apply to all procedures, whereas others (e.g., indications, precautions, protocol guidelines, therapies, outcomes) are specific to the individual type (e.g., upper endoscopy, colonoscopy, ERCP, EUS, capsule). Many articles have explored these quality issues10-12 and have provided similar lists of elements that seem to be important. The ASGE has published quality indicators specifically for upper endoscopy, colonoscopy, ERCP, and EUS.3,13,14 By far, the most comprehensive report to date comes from the prestigious U.S. multisociety task force on ‘‘Quality in technical performance of colonoscopy, and the continuous quality improvement process for colonoscopy.’’15 This document discussed the key issues (and questions needing more research) in 7 topic areas: indications and intervals (guideline adherence), precautions, insertion, withdrawal, biopsy and polypectomy, complications, and pathology interface. For each of these areas, they recommended up to 6 quality-improvement targets. Other groups and organizations have discussed quality issues in more general terms and in the context of credentialing. Thus, the ASGE has published guidelines for credentialing physicians and granting privileges in upper endoscopy, ERCP, and EUS.16-21 The recent report from the National Institutes of Health ‘‘state of the science’’
conference on ERCP made many comments on quality issues.22 These documents speak about adequate training, numbers of procedures, and desirable qualities in endoscopists but include no objective measures of performance, for the obvious reason that there has been no agreement for measures. This is the main rationale for this workshop and discussion.

How to recognize, predict, and measure excellence? There are some factors that make a good experience more likely. Good endoscopic training and extensive experience do not guarantee quality practice, but they certainly make it more likely. Thus, documentation of these and related elements should be a part of any assessment of endoscopists. Appropriate metrics could include the following: d Specialty training and certification (place and dates) d Training and maintenance of competence in life support and sedation d Evidence for continuing education in endoscopy d For each group of procedures, lifetime numbers, total in the last year, and spectrum of practice The proof of quality comes from documentation of performance. There is no substitute for collecting relevant data.23 The ASGE has recommended that endoscopists should collect data prospectively on their endoscopic practice and performance.3 This translates into ‘‘endoscopy report cards.’’24
Report cards for endoscopy The report card is simply an extension of the log books used by trainees to record their performance. It cannot possibly include all of the data elements that have been listed above and in various well-meaning publications. Items should be selected based on ease of data collection and by assumed relative importance. Some items are easily recorded and appear in most reports already (e.g., procedure indication, anatomical extent, duration, diagnosis, immediate unplanned events). Other items are more subjective (e.g., lesion interpretation) or more difficult to record (e.g., delayed complications, endoscopist-specific patient satisfaction). Some items would appear to be more important markers of quality than others. For ERCP, selective cannulation performance and complication rates are obvious key parameters. For colonoscopy, cecal intubation rates and minimum withdrawal times appear to be particularly relevant.15 The U.S. multisociety task force on colonoscopy suggested 25 quality improvement targets (each with goals).15 While such a comprehensive assessment would be ideal, it will be easier to start the process with simpler tools. Once the system is established, the parameters will be refined and expanded. Our ‘‘starter recommendations’’ are given in Appendix 1.
Practical endoscopic metrics
Why should we bother and how? It is likely that patients and payers will increasingly seek help from those with documented expertise and will avoid others. Keeping a report card will provide a competitive advantage. It also is a crucial tool in the evolving use of ‘‘pay for performance’’ in the United States. Those driving that agenda need professional help in determining meaningful quality measures. How to collect, analyze, and use these data was the topic for the second section of our workshop and will be reported separately. The increasing use of electronic endoscopy reporting systems will make this process easy, even automatic.
Endoscopy proctoring, examinations, and diplomas Knowledge of an endoscopist’s training, experience, and some report-card data can provide important data on the quality of his or her practice. But this may not be sufficient, especially when there may be questions about those elements that are more difficult to document precisely, such as the extent of knowledge, skill in lesion recognition, judgment in difficult treatment decisions, and teamwork. We may need additional information from proctoring, as recommended by ASGE.18,19 Another possibility is a formal examination. This would be resource intensive and not without controversy, but examinations are the recognized method for assuring a reasonable level of knowledge and performance in many other fields and usually lead to a diploma. It initially could be piloted for a lower volume, higher-risk procedure such as ERCP. The diploma would be based on data from report cards, an examination of core knowledge, observation of a few cases, and, possibly, some work on simulators. This exercise would require agreement on how to ‘‘score’’ the more subjective elements of a procedure. Unless and until the official agencies (such as the American Board of Internal Medicine [ABIM]) embrace this concept, the ERCP diploma would have a significant impact only if a substantial number of practitioners volunteer to participate.

specific for endoscopy units in the United States, and the agencies that accredit them do not have comprehensive guidelines. Hitherto, inspections have focused on the existence (and compliance with) guidelines for sedation and infection control. These are important, but there are other elements.
Metrics of quality in endoscopy units It is not difficult to list features of endoscopy units that may impact the quality of the procedures being performed in them. 1. Facilities and equipment (and maintenance) 2. Volumes and range of procedures performed 3. Method for credentialing doctors 4. Staffing levels, with appropriate training and certification 5. Leadership and cohesion (retention) 6. Documented policies and compliance systems d Sedation and monitoring d Cleaning and disinfection d Methods for risk minimization 7. Regularly collected safety data d Infection rates, disinfection surveillance d Sedation issues, intubations, prolonged recovery d Accidents d Unplanned admissions 8. Communications d No-show rates d Pathology follow-up system d Surveillance returns (patients with polyps, stents) d Referring physicians 9. Patient feedback d Complaint management d Formal satisfaction surveys An ‘‘endoscopy unit report card’’ could be developed by picking a selection of these criteria, as shown in the Appendix. As part of the endoscopy modernization process in Britain, a ‘‘global rating scale’’ was completed by most of the endoscopy units.25 This was a qualitative self-rating survey dealing mainly with processes instead of numbers and yielded important comparative information. It will be updated.
The excellence of endoscopy units Patients are concerned about their safety, comfort, and dignity during endoscopy, and the efficiency of the process. While endoscopists have a responsibility for these elements and can influence the way the rest of the team functions, there are important quality elements of the endoscopy unit and the staff that can be considered separately. Endoscopists (however talented) cannot work without good facilities, equipment, and a well-trained and motivated staff. While most health care facilities pay some attention to ‘‘quality improvement,’’ the extent to which this percolates down to the endoscopy unit is variable. There is no national quality improvement program 288 GASTROINTESTINAL ENDOSCOPY Volume 63, No. 2 : 2006
What performance level is good enough: benchmarking Endoscopists and units vary in their levels of performance. Not all patients can be managed by the superexperts. The issue then is who decides what constitutes acceptable performance and what that should be. The U.S. multisociety task force for colonoscopy suggested goals (e.g., 95% cecal intubation rates in screening examinations, and 100% compliance with coagulation issues). Other professional bodies have also made similar recommendations (e.g., 90% selective biliary cannulation rate in www.giejournal.org
Cotton et al
ERCP). But, we currently have no idea how much variation really exists in the broad endoscopic community. Aggregated data on cecal intubation rates from acknowledged experts in prospective studies15 paint a much more favorable picture than those from more general audits of broader community practice.26,27 The true picture can be documented only if a large and representative sample of endoscopists and units share and compare data from similar report cards. Benchmarking is the practice of mapping the performance of an individual (endoscopist or unit) against that from a broad spectrum of ‘‘competitors.’’ There are many practical and political issues involved in attempting to aggregate and analyze such data, not least because, by definition, 50% of the doctors and units will be shown to be performing below the mean. These issues were the subject of the second part of the workshop and will be reported separately. Ultimately, informed consumers should be able to judge what is good enough for them. Increasing publicity about variations in performance (e.g., in colonoscopy completion rates), if linked to specific report card data, will drive this agenda. Practitioners with poor outcomes or those who choose not to collect data will be disadvantaged.

We recommend that all endoscopists who are comfortable with their performance should begin to collect data for individual report cards, by using simple data points as shown in Appendix 1. The effort need not be overambitious or burdensome. Let us get something started. The fact that some endoscopists will be reluctant to document and advertise their poor performance should not stop us from doing the right things, right? We should wear our data plainly and proudly as badges of quality.

DISCUSSION No one involved in endoscopy doubts the importance of ensuring the highest possible quality of our processes and procedures. Many patients assume that any doctor who offers a procedure is competent to do it and that all facilities are equally safe (although some may look less appealing). The very simplicity of endoscopy as a ‘‘walk-in, walk-out’’ procedure can lull patients and practitioners alike into a sense of false security. Bad things can and do happen. Gastroenterologists often assume and argue that their procedures are more successful and safer than those performed by others with less focused training, but there is little proof. Our profession must work harder to develop and use methods for documenting performance, such as the report card. It will pay huge dividends eventually. We further call on institutions to incorporate these objective data into their processes for credentialing and recredentialing.
