Physical exam skills are essential to core competencies for physicians in training. It is increasingly difficult to secure time and funding for physician faculty to teach these critical skills. This study was designed to determine whether Patient Educators (PE) (non-physician instructors) in an introductory clinical medicine (ICM) course (1) were as effective as physician faculty in teaching the physical exam, (2) impacted consistency of student performance on a final practical exam, and (3) whether this model was cost effective.
PE were introduced into an ICM course at the University of Minnesota from 2006 to 2008. Each year, students' physical exam competencies were evaluated by a performance-based head-to-toe examination and 6 months later by an objective structured clinical examination (OSCE). Differences in test scores between years and variability (i.e., consistency) among yearly scores were assessed. The cost per student was calculated by considering a stable compensation cost per hour for the required number of physician faculty, standardized patients, and PE in each year.
Mean student performance was statistically lower with PE, but only by two percentage points. The amount of variation within the medical student classes' physical exam skills remained stable as the use of PE expanded. Total educator salary costs per student declined from $449 in 2006 to $196 in 2008.
In terms of sustainability and student performance, the use of trained lay educators has equivalent outcomes and is less costly for physical exam instruction in the pre-clinical years.
体格检查技能对于培训中的医生的核心能力至关重要。越来越难以确保医师教职员工有时间和资金来教授这些关键技能。本研究旨在确定在入门临床医学(ICM)课程中,非医师指导员(PE)(非医师指导员)(1)在教授体检方面是否与医师教职员工一样有效,(2)是否影响学生在期末考试中的表现的一致性,以及(3)这种模式是否具有成本效益。
从 2006 年到 2008 年,PE 被引入明尼苏达大学的 ICM 课程。每年,学生的体格检查能力都通过基于绩效的从头到脚检查进行评估,6 个月后通过客观结构化临床考试(OSCE)进行评估。评估了年度之间测试分数的差异和分数的可变性(即一致性)。通过考虑每年所需医师教职员工,标准化患者和 PE 的稳定补偿费用/小时,计算每位学生的成本。
使用 PE 后,学生的平均表现统计上较低,但仅低了两个百分点。随着 PE 的使用范围扩大,医学生班级体格检查技能的内部变化量保持稳定。每位学生的教育者总薪资成本从 2006 年的 449 美元下降到 2008 年的 196 美元。
就可持续性和学生表现而言,使用经过培训的非专业教育者在临床前几年进行体格检查教学具有同等效果,并且成本更低。
