3 Join Your Colleagues in Orlando for WCOG at ACG07 The International GI Educational Event of the Year! Carol Burke Dear Colleagues, We would like to invite you to join us for a groundbreaking, international educational event. For many years, the American College of Gastroenterology (ACG) and the World Gastroenterology Organisation (WGO), have united on a number of activities and initiatives to advance the field of gastroenterology and hepatology, and ultimately, to improve patient care. This year marks another capstone of collaboration for the ACG and the WGO with the commencement of the World Congress of Gastroenterology at the ACG 07 Scientific Meeting and Postgraduate Course (WCOG at ACG07), October 3-8, at the Orange County Convention Center in Orlando, Florida. This will be the first time in more than 0 years that the World Congress will be held in the U.S. The meeting will provide state-of-the-art education and science by a global faculty focusing on a world-view of GI and hepatology David Bjorkman diseases and treatments and will afford attendees an opportunity to present their research in an international forum. In addition, there will be hands-on endoscopy workshops, small group breakfast and lunch sessions with the experts, and sessions throughout the event that will offer simultaneous Spanish interpretation a first for a World Congress of Gastroenterology. Our goal is that the event will deliver a comprehensive clinical update on the latest in GI and hepatology, and build a sense of community as we all work to advance practice and patient care. In selecting the site for the WCOG at ACG07, there was no better choice than Orlando, Florida. This warm weather destination, considered the Theme Park Capital of the World, is home to Walt Disney World, Universal Studios, SeaWorld, and many other attractions. Thrill-seekers will enjoy the numerous rides while movie fans can explore attractions based on their favorite characters. Orlando is a great vacation destination for adults as well as families with children of all ages. Getting to Orlando is easy. The Orlando International Airport has 800 flights per day and is serviced by 40 airlines. It offers non-stop service from nearly 80 U.S. destinations and 34 international destinations, including but not limited to Bogotá, Santiago, San Salvador, Rio de Janeiro, Mexico City in Latin America; Dublin, London, and Frankfurt in Europe; and Toronto, Montreal, Halifax, and Ottawa in Canada.

22 needs assessment WCOG at ACG07 EDUCATIONAL PROGRAMS Clinical gastroenterology continues to experience an ever-increasing array of options and advancements affecting both the diagnosis and treatment of gastrointestinal (GI) disorders. Gastroenterologists must stay abreast of the diagnostic and treatment options that are available for managing their patients and effectively utilize them while maximizing quality and safety. The multi-faceted pressures of new and increasing scientific developments, pressures from payors and policymakers, and demands by more knowledgeable patients mandate that gastroenterologists find ways to constantly reevaluate the diagnostic techniques and treatment modalities used and mechanisms for delivery in their practices. Declining reimbursement, increased demand for measurement of quality, and an insufficient workforce also remain significant challenges for gastroenterologists and their practices. As a consequence, it is important to identify more efficient ways to obtain the latest scientific knowledge and institute scientifically sound therapy so that the highest quality of patient care can be maintained. This objective, regardless of the specific practice setting, is to guarantee that each individual patient obtains the treatment and service that is the best possible option for their specific needs. The emphasis of ACG s educational efforts focuses on these advancements in diagnosis and treatment options, as well as on the policies, procedures, and guidelines gastroenterologists employ in the overall management of their practices. A primary CME educational program goal is to heighten the knowledge of clinicians and other health care professionals involved in GI patient care in all areas of management, with an emphasis on those conditions with increasing prevalence and those where management continues to present a challenge. Attention is also placed on advanced and improved endoscopic techniques and practice management tools that can increase gastroenterologists efficiency and effectiveness in their daily practice. Colon Cancer Screening Colorectal cancer is the third most commonly diagnosed cancer among both men and women. Colon cancer incidence rates have declined over the last two decades and survival rates have increased. This likely relates at least in part to increased colorectal cancer screening and surveillance, which allows physicians to detect and remove pre-cancerous polyps or diagnose cancers at an early stage. Although these trends are moving in a positive direction, there remains a need to increase the number of individuals being screened. The proper and timely use of existing as well as newer screening tests that may lead to prevention or early diagnosis of specific disease conditions is critical. Increasing the rate of patient participation in colorectal cancer screening and surveillance is also important. Furthermore, providing and quantifying indicators that define a quality colonoscopy, including bowel preparation quality and adenoma detection rates, especially in light of recent findings on the prevalence of flat lesions, is a need that affects gastroenterologists. In addition, it is important that gastroenterologists understand the importance of grading bowel preparation using a validated scale, and that they are familiar with recommendations for the timing of a repeat colonoscopy in exams with inadequate bowel preparation. There is also a need to recognize the potential role that the gastroenterologist plays in minimizing the occurrence of interval cancers. This includes the use of split-dose preparation in their practice as well as the use of proper polyp resection technique. The serrated pathway, which may account for at least 5% of all colorectal cancers, requires gastroenterologists to understand the challenges in detection, resection, and pathological interpretation and classification of these lesions. To aid in surveillance of serrated polyps, gastroenterologists should be aware of an expert panel s recent recommendations: Guidelines for Colonoscopy Surveillance After Screening and Polypectomy: A Consensus Update by the US Multi-Society Task Force on Colorectal Cancer. There has also been a recent update to the surveillance guidelines that includes the addition of recommendations for certain serrated polyps. There is also a need to educate the gastroenterologist on the recent published data that help support recommendations of previous versions of surveillance guidelines. This will hopefully serve to increase physician adherence to the guidelines. As the survival rates from these GI cancers continue to improve, the must continue educating gastroenterologists who provide ongoing care to these patients. This important and evolving educational need must be met in a way that touches on the impact of various forms of cancer on the overall health and quality of life of these patients. Obesity Obesity has drastically increased in prevalence in the United States, from less than 5% in the 960s to over 30% at present. It has been predicted that if the rates continue at their current pace, by 05, 75% of adults will be overweight or obese. Therefore, not only is it imperative for gastroenterologists to be knowledgeable regarding obesity prevention and treatment options, but it is also important that they understand the importance of patient education. Patient education is a necessity to improve compliance and to achieve desired treatment results. In those patients who undergo surgery for the management of obesity, information on the post-surgical complications has become increasingly important. Specifically, endoscopic techniques and management options in these patients can be a challenge. It is essential that gastroenterologists be familiar and up-to-date on endoscopic techniques in this challenging group of patients. These topics, as well as the latest information on what GI conditions are linked to or exacerbated by obesity, have been requested as areas of further education by practicing gastroenterologists. IBD Inflammatory bowel disease is an area of gastroenterology that continues to see important developments in diagnostic and medical therapeutic options. The gastroenterologist must be fully aware of the latest developments in biologic and immunomodulator therapies including safety considerations and their place in patient management. In recent years there have also been many advances made in laboratory, radiographic, and endoscopic modalities that directly impact the diagnosis and management of inflammatory bowel disease and in the surveillance for dysplasia in ulcerative colitis and Crohn s colitis. Education regarding optimizing the use of such modalities is important to the practicing gastroenterologist. The post-surgical management of inflammatory bowel disease patients also continues to be a topic of great importance and one in which the clinician often faces challenges due to the complexity and unpredictability of the condition and the associated decisionmaking process. Hepatology Gastroenterologists are frequently faced with challenges related to liver disorders including hepatitis B and C, NAFLD, hepatic encephalopathy, cirrhosis, and autoimmune liver diseases. Often, the gastroenterologist relies on the expertise of the hepatologist to assist in the management of these patients; however, with hepatologists operating at capacity, the gastroenterologist must be able to offer the best quality of care and treatment options to patients with liver disease. With the increased incidence of NAFLD, practical and clinically relevant physician education is extremely important in this area. Hepatitis C Hepatitis C will be the most dramatically changing area of liver disease over the next few years, and there will be two major areas that will require focus and attention. First, HCV screening recommendations have shifted from the classic risk-based screening to an age-based screening. The CDC and USPFTS have recommended one-time screening of all persons born between 945 and 965. It will be essential that ACG and gastroenterologists educate primary care providers as well as patients about the need for HCV screening. Secondly, there has been a dramatic 0 Register at WorldCongressACG07.org

23 needs assessment WCOG at ACG07 EDUCATIONAL PROGRAMS shift in the treatment of hepatitis C. Compared to the previous treatments, the current treatment regimens are dramatically more effective and have shorter lengths of therapy, and have dramatically fewer adverse side effects. Also, within the next - years, therapy will likely be completely alloral, interferon-free, and perhaps even ribavirin-free. There will be a series of new regimens available, with new ones being introduced at a very rapid pace. Because there will be simple and effective therapies available, there will likely be more gastroenterologists who are willing to treat HCV. For this reason, ACG must work to educate gastroenterologists about the current and upcoming treatments. Also, with the expected rapid development and approval of multiple regimens, ACG must work to have a mechanism in place to allow rapid changes and/or addendums to HCV treatment guidelines. Pancreaticobiliary Pancreaticobiliary diseases can also be extremely challenging to manage, and can vary greatly in complexity and severity. Gastroenterologists play an essential role in both the evaluation and the management of patients with pancreaticobiliary disorders. Cystic neoplasms of the pancreas are more frequently diagnosed and management guidelines have been updated recently as our knowledge base continues to grow. Gastroenterologist offer highly specialized care for such patients, including advanced interventional endoscopic procedures. As endoscopic technology advances, patients are simultaneously becoming more complex, making it essential that gastroenterologists are up-to-date on these management techniques and strategies. Education on the diagnosis and management of various forms of pancreaticobiliary disease including pancreatitis, pancreatic cysts, pancreatic cancer, and biliary disorders is critical to obtaining the best patient outcomes. Functional GI Improvements in the understanding of the pathogenesis and treatment of motility and functional GI disorders continue to progress as research in this area expands. These disorders are among the most common GI disorders in the general population. Understanding the latest science with regard to these disorders and newer treatment modalities is critical to improving clinical outcomes and quality of life for a large group of patients who have been among the most difficult to treat. Understanding the potential role of enteric microbiota and inflammation in these disorders will also help determine the appropriate course of action and play a critical role in managing these challenging conditions. Diarrheal disorders can prove to be challenging to diagnose and manage. Whether it be acute or chronic, caused by a malabsorptive condition, inflammatory, or infectious process, gastroenterologists must be aware of the various potential causes of diarrhea and the most appropriate corresponding treatment options. With the incidence and severity of Clostridium difficile infections increasing in recent years, this is yet another condition that demands close attention by the gastroenterologist. GI Bleeding GI bleeding remains one of the most common yet most challenging issues confronted by the clinical gastroenterologist. New anticoagulants have been released in the last several years, and this new class of drugs has made patients with GI bleeding even more difficult to treat. It is critical that gastroenterologists are frequently updated on these new medications as these patients may require different management strategies than those who are on traditional anticoagulants. Whether the GI bleeding is related to drug therapy, stress ulceration in the intensive care unit, anticoagulation, chronic liver disease, or obscure gastrointestinal bleeding, the gastroenterologist must be up to date on the latest information on strategies to prevent, diagnose, and optimally treat GI bleeding. GERD Gastroesophageal reflux disease is a common condition world-wide and affects 0% of American adults on a weekly basis. An understanding of its pathophysiology, diagnosis, treatment options, and complications is extremely important for the practicing gastroenterologist, and new guidelines have been published on reflux within the past year. While less common, eosinophilic esophagitis appears to be increasing markedly in incidence and has been the subject of intense research leading to recent clinical guidelines. Esophageal dysmotility remains an ongoing challenge, and this field has dramatically changed in the past several years due to the adoption of new diagnostic modalities and an outpouring of outcomes data. This has been particularly significant for achalasia, which also has been the subject of recent consensus guidelines within the past year. Other upper GI conditions including Barrett s esophagus, dyspepsia, peptic ulcer disease, and H. pylori also require a clear understanding. It is important that published evidence-based practice guidelines for these upper GI conditions and many other identified GI disorders be available to the gastroenterologist for their explicit understanding and to enhance their ability to most effectively manage each of their patients. With guidelines published on gastroesophageal reflux disease, eosinophilic esophagitis, and achalasia within the last year, this has been an active area and this new information needs to be disseminated to the gastroenterology community. Endoscopy Rapid technological advancements in endoscopy and other diagnostic and therapeutic areas in gastroenterology creates a need to communicate the latest techniques and strategies for managing everything from patients with altered anatomy to identification and removal of large and difficult polyps to developing practice of natural orifice transluminal endoscopic surgery. Gastroenterologists in a variety of practice settings need to learn and integrate these new therapies into their practice in order to provide state-of-the-art services to their patients. Quality Finally, it is critical that gastroenterologists incorporate quality, safety, and service metrics into their clinical practice. In particular, quality and safety issues in the endoscopy suite need to be addressed in order to improve patient outcomes. Other quality issues dealing with specific disease states and their management in the office practice also need to be addressed by the practicing gastroenterologist. Practice efficiency is also of great importance as the demand for increased efficiency across all settings continues to drive the search for practical tools to positively impact care delivery and patient outcomes. Through the use of evidence-based approaches for treatment and rational public health policy, clinicians need to identify new and innovative ways to deliver care across the community. Ever-expanding access to information on a real-time basis by both clinicians and patients provides unique opportunities as well as challenges to the healthcare delivery system. When this is combined with the pressures associated with increased spending on healthcare in an environment currently trending toward decreased reimbursement and inadequate rewards for the physician who spends more time with the patient, the importance of high-quality continuing medical education for gastroenterologists and their patients cannot be overstated.
