Compliance with the European Working Time Directive has made obvious the need for a surgical skills training system that will produce surgeons fast and reliably. We have previously proposed a model for objective assessment of surgical dexterity. In this paper we aim to place an updated version of that model into the context of a holistic approach on assessment of a trainee's progress towards becoming an independently operating surgeon.
The PAR matrix breaks down an operation into clearly defined skills that need to be successively acquired. It consists of a 3 x 6 table depicting 18 skill-goals. The y-axis is divided into six levels and the x-axis into three columns. The initials of the three skills on each level form the acronym PAR. Each skill is further graded from 1 to 3 (unsatisfactory, competent, good). The levels are: Level 1--posture, address, relaxation; Level 2--pick-up, airtime, rotation; Level 3--placing, angles, rhythm; Level 4--precision, adaptability, reproducibility; Level 5--pace, awareness, relations; Level 6--planning, announce, review/reflexion.
The format of the PAR model is such that it allows trainer and trainee to objectively assess progress, identify deficiencies and strengths and formulate an appropriate plan of action.
Ergonomics and crew resource management skills are essential for a safe operating environment. The PAR matrix may prove helpful in selection of trainees and revalidation of trainee surgeons as a competence and performance testing method, placed in the appropriate training curriculum.
遵守欧洲工作时间指令明显需要一个能够快速可靠地培养外科医生的手术技能培训系统。我们之前提出了一种客观评估手术灵巧性的模型。在本文中,我们旨在将该模型的更新版本置于评估学员成为独立手术医生进展的整体方法的背景下。
PAR 矩阵将手术分解为需要逐步掌握的明确技能。它由一个 3x6 的表格组成,描绘了 18 个技能目标。y 轴分为六级,x 轴分为三列。每个级别的三个技能的首字母形成了 PAR 的缩写。每个技能进一步从 1 到 3 分级(不满意、胜任、良好)。这些级别是:一级——姿势、地址、放松;二级——拿起、空中时间、旋转;三级——放置、角度、节奏;四级——精度、适应性、可重复性;五级——速度、意识、关系;六级——计划、宣布、回顾/反思。
PAR 模型的格式使得培训师和学员能够客观地评估进展情况,识别不足之处和优势,并制定适当的行动计划。
工效学和机组资源管理技能对于安全的手术环境至关重要。PAR 矩阵可能有助于选择学员,并作为一种能力和绩效测试方法对学员外科医生进行再验证,将其置于适当的培训课程中。
