To investigate the effectiveness of a standardized vascular clinic (SVC) in teaching diagnostic and management skills for common vascular problems, as compared with that of the traditional ambulatory setting.
Third-year medical students participating in the required surgical clerkship participated in this study. Students were randomly assigned to attend either a 4-hour SVC experience (group 1, n = 64) or a 4-hour traditional ambulatory experience (group 2, n = 60). Students completed a satisfaction rating scale and a preencounter and postencounter self-efficacy rating scale at the end of the experience. Student t tests were used to compare the groups in the areas of knowledge acquisition, problem solving, clinical skills and satisfaction with the encounter. Analysis of covariance was used to compare the change between pre and post self-efficacy ratings.
Students in group 1 performed significantly higher than students in group 2 in the areas of problem solving, clinical skills, and student satisfaction. They also demonstrated a higher level of confidence in their vascular skills than students assigned to the traditional setting.
The SVC may be more effective in teaching problem-solving and clinical skills. It also may promote more student satisfaction with the experience and confidence in clinical skills than the traditional ambulatory setting.
与传统门诊环境相比，研究标准化血管诊所（SVC）在教授常见血管问题的诊断和管理技能方面的有效性。
参加必修外科实习的三年级医学生参与了本研究。学生被随机分配参加4小时的SVC体验（第1组，n = 64）或4小时的传统门诊体验（第2组，n = 60）。在体验结束时，学生完成了满意度量表以及体验前和体验后的自我效能感量表。使用学生t检验比较两组在知识获取、问题解决、临床技能和对体验的满意度方面的差异。使用协方差分析比较自我效能感评分前后的变化。
在问题解决、临床技能和学生满意度方面，第1组学生的表现明显高于第2组学生。他们在血管技能方面也比分配到传统环境的学生表现出更高的信心。
SVC在教授问题解决和临床技能方面可能更有效。与传统门诊环境相比，它还可能使学生对体验更满意，并对临床技能更有信心。
