Significant information exchange occurs between a doctor and patient through nonverbal communication such as gestures, body position, and eye gaze. In addition, empathy is an important trust-building element in a physician: patient relationship. Previous work validates the use of virtual patients (VP) to teach and assess content items related to history-taking and basic communication skills. The purpose of this study was to determine whether more complex communication skills, such as nonverbal behaviors and empathy, were similar when students interacted with a VP or standardized patient (SP).
Medical students (n = 84) at the University of Florida (UF) and the Medical College of Georgia (MCG) underwent a videotaped interview with either a SP or a highly interactive VP with abdominal pain. In the scenario, a life-sized VP was projected on the wall of an exam room in SP teaching and testing centers at both institutions. VP and SP scripted responses to student questions were identical. To prompt an empathetic response (ie, acknowledging the patients' feelings), during the interview the VP or SP stated "I am scared; can you help me?" Clinicians (n = 4) rated student videotapes with respect to nonverbal communication skills and empathetic behaviors using a Likert-type scale with anchored descriptors.
Clinicians rated students interacting with SPs higher with respect to the nonverbal communication skills such as head nod (2.78 +/- .79 vs 1.94 +/- .44, P < .05), and body lean (2.97 +/- .94 vs 1.93 +/- .58, P < .05), level of immersion in the scenario (3.31 +/- .49 vs 2.26 +/- .52, P < .05), anxiety (1.16 +/- .31 vs 1.45 +/- .33, P < .05), attitude toward the patient (3.24 +/- .43 vs 2.89 +/- .36, P < .05), and asking clearer questions (3.06 +/- .32 vs 2.51 +/- .32, P < .05) compared to the VP group. The students in the SP group also had a higher empathy rating (2.75 +/- .86 vs 2.16 +/- .83, P < .05) and better overall rating (4.29 +/- 1.32 vs 3.24 +/- 1.06, P < .05) than the VP group. Empathy was positively correlated with the observed nonverbal communication behaviors. Eye contact was the most strongly correlated with empathy (r = .57, P < .001), followed by head nod (r = .55, P < .001) and body lean (r = .49, P < .001).
Medical students demonstrate nonverbal communication behaviors and respond empathetically to a VP, although the quantity and quality of these behaviors were less than those exhibited in a similar SP scenario. Student empathy in response to the VP was less genuine and not as sincere as compared to the SP scenario. While we will never duplicate a real physician/patient interaction, virtual clinical scenarios could augment existing SP programs by providing a controllable, secure, and safe learning environment with the opportunity for repetitive practice.
医生和患者之间通过诸如手势、身体姿势和目光接触等非语言交流进行重要的信息交换。此外,同理心是医患关系中建立信任的重要因素。先前的研究证实了使用虚拟患者(VP)来教授和评估与病史采集及基本沟通技巧相关的内容项目。本研究的目的是确定当学生与虚拟患者或标准化患者(SP)互动时,诸如非语言行为和同理心等更复杂的沟通技巧是否相似。
佛罗里达大学(UF)和佐治亚医学院(MCG)的医学生(n = 84)接受了与标准化患者或患有腹痛的高度互动虚拟患者的录像访谈。在该场景中,一个真人大小的虚拟患者被投射到两个机构的标准化患者教学和测试中心的检查室墙上。虚拟患者和标准化患者对学生问题的预设回答是相同的。为了促使产生同理心反应(即承认患者的感受),在访谈过程中虚拟患者或标准化患者说“我很害怕;你能帮我吗?”临床医生(n = 4)使用带有锚定描述词的李克特量表对学生录像的非语言沟通技巧和同理心行为进行评分。
临床医生对与标准化患者互动的学生在诸如点头(2.78 ± 0.79 对 1.94 ± 0.44,P < 0.05)、身体前倾(2.97 ± 0.94 对 1.93 ± 0.58,P < 0.05)、对场景的沉浸程度(3.31 ± 0.49 对 2.26 ± 0.52,P < 0.05)、焦虑程度(1.16 ± 0.31 对 1.45 ± 0.33,P < 0.05)、对患者的态度(3.24 ± 0.43 对 2.89 ± 0.36,P < 0.05)以及提出更清晰问题(3.06 ± 0.32 对 2.51 ± 0.32,P < 0.05)等非语言沟通技巧方面的评分高于虚拟患者组。标准化患者组的学生在同理心评分(2.75 ± 0.86 对 2.16 ± 0.83,P < 0.05)和总体评分(4.29 ± 1.32 对 3.24 ± 1.06,P < 0.05)上也高于虚拟患者组。同理心与观察到的非语言沟通行为呈正相关。目光接触与同理心的相关性最强(r = 0.57,P < 0.001),其次是点头(r = 0.55,P < 0.001)和身体前倾(r = 0.49,P < 0.001)。
医学生表现出非语言沟通行为并对虚拟患者做出同理心反应,尽管这些行为的数量和质量低于在类似标准化患者场景中表现出的行为。与标准化患者场景相比,学生对虚拟患者的同理心反应不那么真实和真诚。虽然我们永远无法复制真实的医患互动,但虚拟临床场景可以通过提供一个可控、安全且有机会进行重复练习的学习环境来增强现有的标准化患者项目。
