BACKGROUND: Experiential learning in medical education, as exemplified by objective structured clinical examinations (OSCEs), is a well-validated approach for improving trainee performance. Furthermore, the Accreditation Council for Graduate Medical Education (ACGME) has identified OSCEs as an ideal method for assessing the core competency of interpersonal and communication skills. The field of inflammatory bowel disease (IBD) challenges clinicians to communicate effectively due to the complex multidisciplinary nature of its management. Here, we describe a novel educational tool (the IBD OSCE) to assess and improve this clinical skillset in Gastroenterology (GI) fellows. METHODS: Twelve second-year GI fellows from 5 fellowship programs participated in a 4-station OSCE. Previously validated OSCE checklists were used to assess the GI fellows' performance in IBD-specific cases. In the first case ("New Diagnosis") the goal of the GI fellow was to educate a patient on her recent diagnosis of ulcerative colitis and to navigate a complex conversation about her risk of colon cancer. In the second case ("Shared Decision Making") the objective was to evaluate a patient with Crohn's disease who would benefit from combination therapy with infliximab and azathioprine. A third case ("Emergency Department Flare") involved evaluating how the fellow performs in the initial triage and management of an ulcerative colitis patient in flare through an observed telephone encounter with an actual emergency department physician. In the final case ("Pre-conception Counseling"), the fellow was asked to discuss the pre-conceptive management of active ulcerative colitis with a "real-life" obstetrician/gynecologist. Each station was videotaped and observed live by faculty gastroenterologists. Checklists were scored independently by a physician-observer and the Standardized Patient (SP), who both provided feedback to the fellow immediately following each case. Fellow performance was scored across multiple domains and individ!

BACKGROUND: Inconsistencies in adherence to evidence-based medicine practice guidelines and quality indicators for inflammatory bowel disease (IBD) have been a recognized limitation in the quality of care afforded to IBD patients. We designed an Objective Structured Clinical Examination (OSCE) to assess many of the core competencies and to provide GI fellows with a simulated, case-based learning experience in the management of IBD patients. To supplement this experience, we provided GI fellows with an easily accessible educational resource in the form of a pocket-sized guide to highlight key evidence-based concepts in IBD education stressed in the OSCE. We assessed the utility of the NYU Gastroenterology Fellowship Training Program Pocket Guide's usefulness, functionality, utilization, and the GI fellows' satisfaction with this educational resource. METHODS: The NYU Gastroenterology Fellowship Training Program's OSCE course included 4 real life IBD clinical scenarios. Five New York City GI training programs and 12 second-year GI fellows participated. Following the OSCE, each fellow was given a pocket guide entitled "NYU Gastroenterology Fellowship Training Program Pocket Guide: Key Concepts in Managing Patients with Inflammatory Bowel Disease." In addition, the pocket guide was given to the remaining 8 NYU GI fellows who did not participate in the OSCE. The white coat pocket-sized guide is comprised of 5 front and back laminated pages, with approximately 2 pages devoted to each OSCE case. Three months following the distribution of the pocket guide, 20 fellows were invited to participate in an online survey about the pocket guide in general as an education tool, and about its specific elements, and the fellows' answers were collected. RESULTS: Sixteen of 20 (80%) fellows responded to the survey. Nearly 94% (15/16) of responders found the pocket guide to be a useful supplement to their fellowship IBD training, and 100% agreed that the guide would have been a useful reference tool to have at the s!

Background: Although vaccination against hepatitis A virus (HAV) and hepatitis B virus (HBV) is recommended for all patients with chronic hepatitis C virus (HCV) infection, physician vaccination practices are suboptimal. Since training for family medicine (FM) and internal medicine (IM) physicians differ, we hypothesised that there are differences in knowledge, attitudes and barriers regarding vaccination against HAV and HBV in patients with chronic HCV between these two groups. Methods: A two-page questionnaire was mailed to 3000 primary care (FM and IM) physicians randomly selected from the AMA Physician Masterfile in 2005. The survey included questions about physician demographics, knowledge and attitudes regarding vaccination. Results: Among the 3000 physicians surveyed, 1209 (42.2%) returned completed surveys. There were no differences between respondents and non-respondents with regard to age, gender, geographic location or specialty. More FM than IM physicians stated that HCV+ patients should not be vaccinated against HAV (23.7% vs. 11.8%, p < 0.001) or HBV (21.9% vs. 10.6%, p < 0.001). FM physicians were also less likely than IM physicians to usually/always test HCV+ patients for immunity against HAV (33.9% vs. 48.6%, p < 0.001) or against HBV (50.8% vs. 68.0%, p < 0.001). There were numerous barriers to HAV and HBV vaccination identified. The median number of barriers was 3 for FM physicians and 2 for IM physicians (p < 0.001). Conclusions: Despite recommendations to vaccinate against HAV and HBV in patients with chronic HCV infection, physicians often do not test or vaccinate susceptible individuals. Interventions are needed to overcome the barriers identified and improve vaccination rates.

Purpose: Bariatric surgery can achieve sustained weight loss compared to medical management. Among bariatric surgeries, laparoscopic adjustable gastric banding (LAGB) is less-invasive and potentially reversible. LAGB may decrease BMI through restriction of food intake, behavior changes, satiety and digestive hormone levels. The dramatic reduction of appetite observed with LAGB can be ameliorated if the band is underfilled. This effect has not been well evaluated in terms of patient behavior and hormonal changes. Our aim was to assess outcomes related to eating behavior, insulinotropic hormones, and weight change before and after temporary gastric band release. Methods: Adults >= 18 yeaars of age who previously underwent LAGB and achieved successful weight loss were enrolled. All patients underwent standardized evaluation including anthropometric measurements and completion of the Three-Factor Eating Questionnaire (TEFQ-R18) before and after a period of 14 days during which the band was completely loosened. At baseline and follow-up, blood was collected after an overnight fast and 1h after a standard high protein meal, and levels of insulinotropic hormones determined. Results: The mean age of the study cohort (9 women and 6 men) was 42 +/-14 years with mean pre-band adjustment BMI of 32.9 +/- 5.6 and mean waist circumference of 40 +/- 7 inches. All patients had >30% percent reduction in weight within 12-months of the LAGB and demonstrated a lower degree but continued weight loss in the 6-months before study enrollment. Compared to baseline values for the TEFQ-R18, within 2-weeks of loosening the band, cognitive restraint was reduced (11.2 +/- 3 vs. 10.4 +/- 4), while there was a significant increase in both disinhibition (6.4 +/- 3 vs. 9.4 +/- 3, p=0.004) and hunger scores (4.1 +/- 3 vs. 8.0 +/- 3, p=0.004). Compared to baseline, at follow-up insulin output in response to a meal showed a downward trend [Median (IQR) 1,110 (728-1,332) vs. 621 (375-1,325) pg/ml; p=0.21] while leptin was significantly elevated [10,400 (6,030-11,350) vs. 13,700 (10,500-43,900) pg/ml; p=0.001]. Consistent with these findings BMI significantly increased (32.9 +/- 5.6 vs. 34.5 +/- 5.6, p=0.001) along with waist size (40 +/- 7 vs 42 +/- 6, p=0.003). The amount of weight regained within two weeks, returned the cohort to the weight loss level noted at the 12-month post LAGB time point. Conclusion: LAGB adjustment continues to impact eating behavior, satiety hormones, and body weight beyond the initial 12-months following placement. Complete loosening of the LAGB can result in rapid changes in eating behavior, insulinotropic hormones, and significant changes in BMI. Careful adjustment of the band is necessary for continued maintenance of weight loss
