s / International Journal of Surgery 23 (2015) S15eS134 S18 completed by 511 pre-clinical medical students. A free hand comment section was also included. Results: 85% and 98% of students agreed or strongly agreed that anatomy is an interesting subject and an important component of medical education respectively. 63% agreed or strongly agreed that Anatomage significantly improved their understanding of 3D anatomy. 78% agreed or strongly agreed that the interactive nature of Anatomage made learning anatomy more engaging. Anatomage rated 4th out of 5 anatomy learning modalities. A large proportion of students volunteered that they needed more time at the Anatomage table. Conclusion: Anatomage can play an important role in the acquisition of 3D anatomy knowledge and promises to be a useful adjunct to traditional learning modalities, which still rank highly. Early surveys reveal that students desire more time at the table to fully realise the educational potential of this technology. 0939: AN OVERVIEW OF TEAMWORK TRAINING AND ASSESSMENT IN MODERN SURGICAL PRACTICE G. Whittaker , H. Abboudi , M. Khan , P. Dasgupta , K. Ahmed . King's College London, UK; Guy's and St Thomas' NHS Foundation Trust, UK Aim: To provide an overview of teamwork training and assessment tools available for surgery and review the internal validation evidence supporting each tool, with subsequent formation of a framework for team training. Methods: A comprehensive literature search was conducted to identify teamwork assessment tools using MEDLINE (1946 to December 2014), EMBASE (1974 to December 2014), and PsycINFO (1806 to December 2014) databases. The following keywords were used in combination: “teamwork”, “team work”, “team-working”, “non-technical skills”, “nontechnical skills”; “assessment”, “assessing”; “surgery”, “surgical”, and “surgeons”. Validation evidence was gathered using a similar search, combining each tool with “validation”, “validity”, and “valid” keywords. Results: 590 publications and conference abstracts of potential relevance were discovered and subsequently screened to identify seven tools. Each tool has at least one item of evidence supporting validity, though the number and quality varies greatly. The Non-Technical Skills for Surgeons (NOTSS) tool demonstrated the highest level of validity and has also shown reliability and acceptability in practice. Conclusion: Teamwork training and assessment are important aspects of clinical practice which should be core themes of current surgical curricula. Integration of the NOTSS tool into early surgical training should be encouraged to meet evolving requirements of surgeons. Medical Student Short Paper Session 0087: INCIDENCE AND OUTCOMES OF POLYOMAVIRUS INFECTION IN 639 KIDNEY TRANSPLANT RECIPIENTS: ARE HIGH IMMUNOLOGICAL RISK CHARACTERISTICS MORE RELEVANT THAN SPECIFIC INDUCTION OR MAINTENANCE IMMUNOSUPPRESSIVE REGIMENS?

Barts and The London School of Medicine and Dentistry, UK; 2 The Royal London Hospital, UK Aim: Polyomavirus-associated nephropathy (PVAN) is a recognized cause for graft dysfunction and allograft loss. Over-immunosuppression is the main risk factor for the development of PVAN but the role of donor and recipient characteristics is still unclear. Methods: In this single centre cohort study we prospectively collected data to evaluate incidence, outcomes and risk factors of Polyomavirus infection in 639 consecutive KTx performed between 2007 and 2013. Results: During amean follow up of 4.5 years, viraemiawas detected in 54/ 639 patients (8.4%); 26/639 recipients (4.1%) had biopsy-proven PVAN. Death-censored graft loss rate was significantly higher in patients with PVAN compared to recipients with no viraemia: 41.7% (10/24) vs.14.5% (76/ 523), respectively (p < 0.05). After immunosuppression reduction, 43/54 patients (79.6%) had no significant viraemia; four patients (7.4%) had acute rejection, two (3.7%) had ureteric stenosis. The independent risk factors were: recipient BMI, Afro-Caribbean recipient ethnicity, older donor age, higher DRo University of
