The purpose of this study was to evaluate the pelvic and breast examination skills of a group of interns who were entering obstetrics and gynecology and internal medicine and to determine whether previous experience predicts performance.
This was a prospective study that, with the use of an examination with a standardized format of 26 skills, assessed the performance of 10 interns who were entering internal medicine and 9 interns who were entering obstetrics and gynecology. chi(2) analysis and Fisher exact tests were used.
There was no significant difference in overall performance on the pelvic and breast examinations between the two groups. The obstetrics and gynecology interns performed significantly better (P<.05) on the three skills that assessed professional conduct. There was considerable variability within each group. There was no correlation between previous clinical experience and performance on the skills assessment, nor was there a correlation between perceived competence and actual performance.
Previous clinical experience does not predict performance in a standardized assessment of pelvic and breast examination skills nor does it account for the great variability in competence levels in interns who are entering obstetrics and gynecology and internal medicine.
本研究旨在评估一组即将进入妇产科和内科的实习生的盆腔检查和乳房检查技能，并确定既往经验是否能预测其表现。
这是一项前瞻性研究，采用包含26项技能的标准化检查形式，评估了10名即将进入内科的实习生和9名即将进入妇产科的实习生的表现。使用卡方分析和Fisher精确检验。
两组在盆腔和乳房检查的总体表现上无显著差异。妇产科实习生在评估职业行为的三项技能上表现显著更好（P<0.05）。每组内部存在相当大的变异性。既往临床经验与技能评估表现之间无相关性，感知能力与实际表现之间也无相关性。
既往临床经验不能预测盆腔和乳房检查技能标准化评估中的表现，也不能解释即将进入妇产科和内科的实习生能力水平的巨大差异。
