Non-technical skills curriculum incorporating simulation-based training improves performance in colonoscopy among novice endoscopists: Randomized controlled trial.

BACKGROUND AND AIMS: Non-technical skills (NTS), involving cognitive, social and interpersonal skills that complement technical skills, are important for the completion of safe and efficient procedures. We investigated the impact of a simulation-based curriculum with dedicated NTS training on novice endoscopists' performance of clinical colonoscopies. METHODS: A single-blinded randomized controlled trial was conducted at a single center. Novice endoscopists were randomized to a control curriculum or a NTS curriculum. The control curriculum involved a didactic session, virtual reality (VR) simulator colonoscopy training, and integrated scenario practice using a VR simulator, a standardized patient, and endoscopy nurse. Feedback and training were provided by experienced endoscopists. The NTS curriculum group received similar training that included a small-group session on NTS, feedback targeting NTS, and access to a self-reflective NTS checklist. The primary outcome was performance during two clinical colonoscopies, assessed using the Joint Advisory Group Direct Observation of Procedural Skills (JAG DOPS) tool. RESULTS: Thirty-nine participants completed the study. The NTS group (n = 21) had superior clinical performance during their first (P < 0.001) and second clinical colonoscopies (P < .0.001), compared to the control group (n = 18). The NTS group performed significantly better on the VR simulator (P < 0.05) and in the integrated scenario (P < 0.05). CONCLUSION: Our findings demonstrate that dedicated NTS training led to improved performance of clinical colonoscopies among novices.

Protocol for a randomised trial evaluating the effect of applying gamification to simulation-based endoscopy training.

BACKGROUND: Simulation-based training (SBT) provides a safe environment and effective means to enhance skills development. Simulation-based curricula have been developed for a number of procedures, including gastrointestinal endoscopy. Gamification, which is the application of game-design principles to non-game contexts, is an instructional strategy with potential to enhance learning. No studies have investigated the effects of a comprehensive gamification curriculum on the acquisition of endoscopic skills among novice endoscopists. METHODS AND ANALYSIS: Thirty-six novice endoscopists will be randomised to one of two endoscopy SBT curricula: (1) the Conventional Curriculum Group, in which participants will receive 6 hours of one-on-one simulation training augmented with expert feedback and interlaced with 4 hours of small group teaching on the theory of colonoscopy or (2) the Gamified Curriculum Group, in which participants will receive the same curriculum with integration of the following game-design elements: a leaderboard summarising participants' performance, game narrative, achievement badges and rewards for top performance. In line with a progressive learning approach, simulation training for participants will progress from low to high complexity simulators, starting with a bench-top model and then moving to the EndoVR virtual reality simulator. Performance will be assessed at three points: pretraining, immediately post-training and 4-6 weeks after training. Assessments will take place on the simulator at all three time points and transfer of skills will be assessed during two clinical colonoscopies 4-6 weeks post-training. Mixed factorial ANOVAs will be used to determine if there is a performance difference between the two groups during simulated and clinical assessments. ETHICS AND DISSEMINATION: Ethical approval was obtained at St. Michael's Hospital. Results of this trial will be submitted for presentation at academic meetings and for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT03176251.

Supplemental Vitamins and Minerals for CVD Prevention and Treatment.

The authors identified individual randomized controlled trials from previous meta-analyses and additional searches, and then performed meta-analyses on cardiovascular disease outcomes and all-cause mortality. The authors assessed publications from 2012, both before and including the U.S. Preventive Service Task Force review. Their systematic reviews and meta-analyses showed generally moderate- or low-quality evidence for preventive benefits (folic acid for total cardiovascular disease, folic acid and B-vitamins for stroke), no effect (multivitamins, vitamins C, D, ß-carotene, calcium, and selenium), or increased risk (antioxidant mixtures and niacin [with a statin] for all-cause mortality). Conclusive evidence for the benefit of any supplement across all dietary backgrounds (including deficiency and sufficiency) was not demonstrated; therefore, any benefits seen must be balanced against possible risks.

Simulation-Based Training of Non-Technical Skills in Colonoscopy: Protocol for a Randomized Controlled Trial.

BACKGROUND: Non-technical skills (NTS), such as communication and professionalism, contribute to the safe and effective completion of procedures. NTS training has previously been shown to improve surgical performance. Moreover, increases in NTS have been associated with improved clinical endoscopic performance. Despite this evidence, NTS training has not been tested as an intervention in endoscopy. OBJECTIVE: The aim of this study is to evaluate the effectiveness of a simulation-based training (SBT) curriculum of NTS on novice endoscopists' performance of clinical colonoscopy. METHODS: Novice endoscopists were randomized to 2 groups. The control group received 4 hours of interactive didactic sessions on colonoscopy theory and 6 hours of SBT. Hours 5 and 6 of the SBT were integrated scenarios, wherein participants interacted with a standardized patient and nurse, while performing a colonoscopy on the virtual reality (VR) simulator. The NTS (intervention) group received the same teaching sessions but the last hour was focused on NTS teaching. The NTS group also reviewed a checklist of tasks relevant to NTS concepts prior to each integrated scenario case and was provided with dedicated feedback on their NTS performance during the integrated scenario practice. All participants were assessed at baseline, immediately after training, and 4 to 6 weeks post-training. The primary outcome measure is colonoscopy-specific performance in the clinical setting. RESULTS: In total, 42 novice endoscopists completed the study. Data collection and analysis is ongoing. We anticipate completion of all assessments by August 2017. Data analysis, manuscript writing, and subsequent submission for publication is expected to be completed by December 2017. CONCLUSIONS: Results from this study may inform the implementation of NTS training into postgraduate gastrointestinal curricula. NTS curricula may improve attitudes towards patient safety and self-reflection among trainees. Moreover, enhanced NTS may lead to superior clinical performance and outcomes in colonoscopy.
