目的：我们评估了四年级医学生（MS4）在四年级伊始以及7个月后的缝合技能表现及保持情况。
方法：进入外科专业的四年级医学生在四年级开始时被随机分为两组，一组接受基于熟练度的缝合/打结课程（干预组，n = 11），另一组不接受培训（对照组，n = 10）。在基线和7个月时评估时间和技术熟练度（TP，熟练度≥3）。将其表现与过去参加“训练营”的四年级医学生、一年级住院医师和二年级住院医师进行比较。数据以均值±标准差表示。
结果：在基线时，干预组和对照组的四年级医学生完成总任务的时间相似（848±199秒对845±209秒），技术熟练度得分也相似（1.8±0.15对1.8±0.3）。在7个月时，干预组四年级医学生完成总任务的时间更快（549±80秒对719±151秒，P <.01），平均技术熟练度得分更高（3.3±0.6对2.1±0.4，P <.001）。干预组四年级医学生在7个月时的表现也优于参加“训练营”的四年级医学生（662±171秒和2.6±0.5，P <.04），且与一年级住院医师（601±74秒，技术熟练度2.7±0.7秒）和二年级住院医师期末（475±81秒和3.6±0.3秒）表现相似。
结论：在四年级早期教授基于熟练度的缝合和打结课程，与不进行培训或传统的“训练营”项目相比，可提高四年级医学生的表现。
Purpose. We evaluated suturing skills performance and retention in senior medical students (MS4) at the beginning of their fourth year and 7 months later.Methods. MS4 students entering a surgery specialty were randomized to a proficiency-based suturing/knot-tying curriculum at the beginning of fourth year (Intervention, n = 11) versus no training (Control, n = 10). Time and technical proficiency (TP, proficiency >= 3) were assessed at baseline and 7 months. Performance was compared with past "Boot-Camp" MS4, categorical PGY-1 interns and PGY-2 residents. Data are mean +/- SD.Results. At baseline, Intervention and Control MS4 had similar total task times (848 +/- 199 vs 845 +/- 209 seconds). and TP scores (1.8 +/- 0.15 vs 1.8 +/- 0.3). At 7 months,, Intervention MS4 total task times were faster (549 80 vs 719 151 seconds, P < .01) and mean TP scores greater (3.3 +/- 0.6 vs 2.1 vs 0.4, P < .001) than Control MS4. Intervention MS4 also performed better at 7 months than Boot-Camp MS4 (662 +/- 171 seconds and 2.6 +/- 0.5,P < .04) and were similar to PGY-1 interns (601 +/- 74 seconds, TP 2.7 +/- 0.7 seconds) and end of PGY-2 residents (475 +/- 81 seconds and 3.6 +/- 0.3 seconds).Conclusion. A proficiency-based suturing and knot-tying curriculum taught early in the fourth year results in improved MS4 performance compared with no training or a traditional "boot camp" program.
