BackgroundPeer tutoring has been described as “people from similar social groupings who are not professional teachers helping each other to learn and learning themselves by teaching”. Peer tutoring is well accepted as a source of support in many medical curricula, where participation and learning involve a process of socialisation. Peer tutoring can ease the transition of the junior students from the university class environment to the hospital workplace. In this paper, we apply the Experienced Based Learning (ExBL) model to explore medical students’ perceptions of their experience of taking part in a newly established peer tutoring program at a hospital based clinical school.MethodsIn 2014, all students at Sydney Medical School – Central, located at Royal Prince Alfred Hospital were invited to voluntarily participate in the peer tutoring program. Year 3 students (n = 46) were invited to act as tutors for Year 1 students (n = 50), and Year 4 students (n = 60) were invited to act as tutors for Year 2 students (n = 51). Similarly, the ‘tutees’ were invited to take part on a voluntary basis. Students were invited to attend focus groups, which were held at the end of the program. Framework analysis was used to code and categorise data into themes.ResultsIn total, 108/207 (52 %) students participated in the program. A total of 42/106 (40 %) of Year 3 and 4 students took part as tutors; and of 66/101 (65 %) of Year 1 and 2 students took part as tutees. Five focus groups were held, with 50/108 (46 %) of students voluntarily participating. Senior students (tutors) valued the opportunity to practice and improve their medical knowledge and teaching skills. Junior students (tutees) valued the opportunity for additional practice and patient interaction, within a relaxed, small group learning environment.ConclusionStudents perceived the peer tutoring program as affording opportunities not otherwise available within the curriculum. The peer teaching program provided a framework within the medical curriculum for senior students to practice and improve their medical knowledge and teaching skills. Concurrently, junior students were provided with a valuable learning experience that they reported as being qualitatively different to traditional teaching by faculty.

PurposePeer tutoring offers a valuable method of enhancing students’ learning experience in medical school. Junior students learn from senior peers to reinforce curriculum content in an engaging community environment. The aim of our study was to assess tutees’ perceptions of a formal peer tutoring program at the Central Clinical School of Sydney Medical School. We used the learning theory of the community of practice in order to understand tutees’ perspectives.Patients and methodsAll Year 1 and Year 2 students within the Central Clinical School were invited to be tutored by Year 3 and Year 4 students, respectively. Tutor pairs taught a group of three to four tutees fortnightly, and the tutorials were largely clinically based. A questionnaire containing 13 closed items and four open-ended questions regarding their experiences in the program was distributed to the tutees. Descriptive statistics were used to analyze the data.ResultsA total of 66 of 101 (65%) Year 1 and Year 2 students took part as tutees and 42 of 106 (40%) students as tutors. The tutees’ response rate was 53% (35/66). Results were largely positive, with 97% of the tutees enjoying the program, 90% showing interest in tutorial topics, 91% feeling a sense of community, 100% wanting to take part next year, 97% finding small groups effective, and 97% and 91% feeling an improved understanding of medical concepts and clinical skills, respectively. Tutees perceived the most useful aspects to be learning and revision and advice from experienced peers. The most frequent suggestion for improvement was to resolve scheduling conflicts.ConclusionTutees found the peer tutoring program to be valuable in learning and revision, establishing a community, and gaining practical skills and advice through a small-group format. The community of practice framework was useful in identifying these areas of benefit, demonstrating that a peer tutoring program such as this can provide an enhanced learning environment for tutees.

Considerable variability exists in adherence to practice guidelines for Barrett's esophagus (BE). Rapid advances in management approaches to BE led to a new American Gastroenterological Association (AGA) medical position statement in 2011. Our aim was to assess how well members of the AGA Clinical Practice section adhered to these guidelines. A self-administered survey incorporating questions on diagnostic criteria, cancer risk estimates, screening, surveillance, and therapeutics for BE was distributed electronically to 5850 North American members of the AGA Clinical Practice section. The response rate was 470 of 2040 opened e-mails (23%). Intestinal metaplasia was required for diagnosis of BE by 90%, but the Prague classification was used by only 53% of those aware of it. The annual risk of progression to esophageal adenocarcinoma was reported as 0.1-0.5% by 76%. Screening practices were variable, with 35% screening all patients with chronic gastroesophageal reflux disease and 15% repeating endoscopy in patients with gastroesophageal reflux disease following a negative screening. Surveillance guidelines were followed by 79% for nondysplastic BE and 86% for low-grade dysplasia, with expert pathology confirmation of dysplasia reported by 86%. Proton pump inhibitor dosing was variable, with 18% administering twice-daily doses and 30% titrating dose to symptoms. Ablation therapy was recommended by 6% for nondysplastic BE, 38% for low-grade dysplasia, and 52% for high-grade dysplasia. There is satisfactory adherence to the new AGA guidelines with respect to diagnosis, cancer risk estimates, and surveillance intervals in a select group of respondents. However, adherence continues to be variable in the use of the Prague classification, screening, and dosing of antisecretory therapy. Use of ablation therapy increases with grade of dysplasia. The reason for continued variability in adherence to BE practice guidelines remains unclear, and more evidence-based guidance is required to enhance clinical practice.

BackgroundThere has been worldwide debate on lymphadenectomy for gastric cancer, with increasing consensus on performing an extended (D2) resection. There is a paucity of data in Australia. Our aim is to compare overall outcomes between a D1 and D2 lymphadenectomy for gastric cancer in a single specialist unit.MethodsWe performed a retrospective analysis on patients who underwent a curative primary gastric resection for gastric adenocarcinoma between January 1996 and April 2016, primary outcomes included overall survival (OS) and disease-free survival (DFS). Propensity score matching (PSM) analysis was used to balance covariates between D1/D1+ and D2 groups. Kaplan-Meier survival curves of D1/D1+ versus D2 were constructed and evaluated using the log-rank test with subgroup analyses for pathological node (pN) status. Multiple Cox proportional hazards model was used to determine predictors of overall survival.ResultsTwo hundred four patients underwent a gastrectomy, 54 had D1/D1+, and 150 had a D2 lymphadenectomy. After PSM, there were 39 patients in each group, the 10-year OS for D1/D1+ was 52.1 and 76.2% for D2 (p = 0.008), and 10-year DFS was 35% for D1 and 58.1% for D2 (p = 0.058). Subgroup analysis showed that node-negative (N0) patients had improved 5-year OS for D2 (90.9%), compared to D1/D1+ (76.4%) (p = 0.028). There was no difference in operative mortality between the groups (D1 vs D2: 2 vs 0%, p = 0.314), nor in post-operative complications (p = 0.227). Multiple Cox analysis showed advanced tumor stage (stages III and IV), and lymphadenectomy type (D1) and the presence of postoperative complications were independent predictors of poor overall survival.ConclusionsD2 lymphadenectomy with spleen and pancreas preservation can be performed safely on patients with gastric adenocarcinoma. Significant improvement in overall survival is observed in patients with N0 disease who underwent D2 lymphadenectomy without increasing operative morbidity or mortality. This paper supports the notion of a global consensus for a D2 lymphadenectomy, particularly in the Western context.
