RESUMO
BACKGROUND: Simulation-based training is one way to improve basic competence for surgical trainees and thus improve patient safety. Closed reduction and percutaneous pinning of a supracondylar humerus fracture is a common procedure that encompasses many basic orthopaedic skills and has been identified as a residency milestone. Despite this, no quantitative tools exist to help learners attain this basic skill. This study seeks to validate a quantitative, low-cost simulation-based training tool for teaching orthopaedic surgery trainees the fundamentals of fracture stabilization with pins. METHODS: Two low-cost models were developed with simulated cancellous bone blocks and cortical bone sheets: a pinning agility tool to teach pin placement and redirection, and a low-cost construct stability tool to replicate pinning. A high-cost construct stability tool was cut using a pediatric supracondylar humerus model to simulate pinning a real fracture. Construct stability was assessed by adding weight until â¼1.6 mm of displacement was observed. Participants were tested naively on all 3 models and then completed a training session using only the low-cost models. Performance following training was then assessed and compared with fellowship-trained pediatric orthopaedic surgeons. Participants also rated their preintervention and postintervention confidence, skill, and knowledgeability. RESULTS: A total of 18 novice trainees participated (10 PGY1 and PGY2 orthopaedic surgery residents and 8 medical student members of the orthopaedic surgery interest club), whereas the reference group consisted of 7 orthopaedic surgery attendings. The subjects significantly improved their scores on both the low-cost (P=0.002) and high-cost (P<0.001) construct stability tools after the training with only the low-cost tools. Compared with the attending benchmark, trainee scores improved on the high-fidelity model from 31% preintervention to 86% postintervention and their pinning times decreased by 38%. Trainees reported increased knowledge, skill, and confidence after the intervention (P<0.001). CONCLUSIONS: A novel, low-cost simulation model and training session for supracondylar humerus fracture pinning resulted in improved performance in stabilizing a supracondylar humerus model and increased trainee knowledgeability, confidence, and skill. LEVEL OF EVIDENCE: Level II-economic.

IMPORTANCE: The increasing legalization of euthanasia and physician-assisted suicide worldwide makes it important to understand related attitudes and practices. OBJECTIVE: To review the legal status of euthanasia and physician-assisted suicide and the available data on attitudes and practices. EVIDENCE REVIEW: Polling data and published surveys of the public and physicians, official state and country databases, interview studies with physicians, and death certificate studies (the Netherlands and Belgium) were reviewed for the period 1947 to 2016. FINDINGS: Currently, euthanasia or physician-assisted suicide can be legally practiced in the Netherlands, Belgium, Luxembourg, Colombia, and Canada (Quebec since 2014, nationally as of June 2016). Physician-assisted suicide, excluding euthanasia, is legal in 5 US states (Oregon, Washington, Montana, Vermont, and California) and Switzerland. Public support for euthanasia and physician-assisted suicide in the United States has plateaued since the 1990s (range, 47%-69%). In Western Europe, an increasing and strong public support for euthanasia and physician-assisted suicide has been reported; in Central and Eastern Europe, support is decreasing. In the United States, less than 20% of physicians report having received requests for euthanasia or physician-assisted suicide, and 5% or less have complied. In Oregon and Washington state, less than 1% of licensed physicians write prescriptions for physician-assisted suicide per year. In the Netherlands and Belgium, about half or more of physicians reported ever having received a request; 60% of Dutch physicians have ever granted such requests. Between 0.3% to 4.6% of all deaths are reported as euthanasia or physician-assisted suicide in jurisdictions where they are legal. The frequency of these deaths increased after legalization. More than 70% of cases involved patients with cancer. Typical patients are older, white, and well-educated. Pain is mostly not reported as the primary motivation. A large portion of patients receiving physician-assisted suicide in Oregon and Washington reported being enrolled in hospice or palliative care, as did patients in Belgium. In no jurisdiction was there evidence that vulnerable patients have been receiving euthanasia or physician-assisted suicide at rates higher than those in the general population. CONCLUSIONS AND RELEVANCE: Euthanasia and physician-assisted suicide are increasingly being legalized, remain relatively rare, and primarily involve patients with cancer. Existing data do not indicate widespread abuse of these practices.
