There is currently a need for objective measures of surgical competence. Such measures should assess knowledge, judgment, and manual skills. The Fundamentals of Laparoscopic Surgery (FLS) program was developed by the Society of American Gastrointestinal and Endoscopic Surgeons to meet these criteria. The FLS assessment includes a multiple-choice cognitive test and a manual skills test. We present the results of validation studies of this novel assessment tool.
Beta testing of the FLS examination was undertaken at 7 sites by 70 surgeons representing 4 levels of experience and training. Surgeons provided information about their prior experience and indicated a self-assessment of their laparoscopic competence. Results were assessed by ANOVA followed by orthogonal contrasts.
Cognitive performance by training level: There was no difference between fellows and staff in percentage of questions answered correctly, but there was a discrepancy between junior and senior residents and between residents and senior surgeons (p < 0.01). Cognitive performance by laparoscopic experience quartiles: There were notable contrasts between the first and second quartiles of experience (p < 0.02) and between the third and fourth quartiles (p < 0.01). No marked difference was found between the second and third quartiles. Cognitive performance compared with self-assessment: Test results were substantially different (p < 0.01) between test-takers who assessed themselves as "better than average" and those who assessed themselves as "average" or "below average." Manual skills performance by training level: The major difference was found between junior residents versus senior residents, fellows or staff (p < 0.01). Manual skills performance by laparoscopic experience level: Differences were primarily seen between the first two quartiles and the last two quartiles of laparoscopic experience (p < 0.001). Manual skills performance compared with self-assessment: Those who assessed themselves as "above average" in laparoscopic skill performed markedly better than those indicating they had "average" or "below average" skill (p < 0.01).
Beta test results for the FLS examination demonstrate satisfactory reliability, appropriate psychometric properties, and substantial initial validity. The FLS project is one of the first validated surgical education efforts to assess the competence of surgeons in a specific field.
目前需要对外科手术能力进行客观评估。此类评估应涵盖知识、判断力和手动技能。美国胃肠与内镜外科医师协会制定了腹腔镜手术基础(FLS)项目以满足这些标准。FLS评估包括多项选择题认知测试和手动技能测试。我们展示了这种新型评估工具的验证研究结果。
由代表4个经验和培训水平的70位外科医生在7个地点对FLS考试进行了β测试。外科医生提供了他们既往经验的信息,并对自己的腹腔镜手术能力进行了自我评估。结果通过方差分析及正交对比进行评估。
按培训水平划分的认知表现:研究员与 staff 在正确回答问题的百分比上没有差异,但初级和高级住院医师之间以及住院医师与资深外科医生之间存在差异(p < 0.01)。按腹腔镜经验四分位数划分的认知表现:经验的第一和第二四分位数之间(p < 0.02)以及第三和第四四分位数之间(p < 0.01)存在显著差异。第二和第三四分位数之间未发现明显差异。与自我评估相比的认知表现:自我评估为“优于平均水平”的考生与评估自己为“平均水平”或“低于平均水平”的考生之间,测试结果存在显著差异(p < 0.01)。按培训水平划分的手动技能表现:主要差异存在于初级住院医师与高级住院医师、研究员或 staff 之间(p < 0.01)。按腹腔镜经验水平划分的手动技能表现:差异主要出现在腹腔镜经验的前两个四分位数与后两个四分位数之间(p < 0.001)。与自我评估相比的手动技能表现:自我评估腹腔镜技能为“高于平均水平”的人比表明自己技能为“平均水平”或“低于平均水平”的人表现明显更好(p < 0.01)。
FLS考试的β测试结果显示出令人满意的可靠性、适当的心理测量特性和较高的初始效度。FLS项目是首批经过验证的外科教育举措之一,旨在评估外科医生在特定领域的能力。
