The authors assessed resident learning and retention of knowledge from resident-prepared chest radiology conferences.
Radiology residents presented five chest conferences to their peers during a 5-month interval; the conferences were modeled on a case presentation format. Tests were given 5 minutes before each conference (pretest) and immediately after each conference (posttest). The tests were readministered as a final examination 6 months later, at which time the residents were asked to evaluate the conference format.
Conference attendance ranged from six to 11 residents. Mean posttest scores were statistically significantly higher than mean pretest scores (P < .0001). Six-month retention scores were higher than pretest scores (P < .05) but lower than posttest scores (P < .05). On a scale of 1-6, with 1 representing strongly disagree and 6 strongly agree, residents strongly agreed that the conferences provided an excellent learning experience (mean score, 5.27).
Resident-prepared conferences are effective for teaching residents chest radiology. Resident testing at 6 months demonstrated retention of knowledge above pretest levels but lower than posttest levels.
作者评估了住院医师通过自己准备的胸部放射学会议所获得的学习情况及知识留存情况。
放射科住院医师在5个月的时间间隔内为同行举办了5次胸部会议；这些会议采用病例展示的形式。在每次会议前5分钟（预测试）和会议结束后立即（后测试）进行测试。6个月后，这些测试作为期末考试重新进行，届时要求住院医师对会议形式进行评估。
参加会议的住院医师人数从6人到11人不等。后测试的平均分数在统计学上显著高于预测试的平均分数（P < .0001）。6个月的知识留存分数高于预测试分数（P < .05），但低于后测试分数（P < .05）。在1至6分的评分标准中，1表示强烈不同意，6表示强烈同意，住院医师强烈认为这些会议提供了极好的学习体验（平均分数为5.27）。
住院医师准备的会议对于教授住院医师胸部放射学是有效的。6个月时对住院医师的测试表明，他们的知识留存高于预测试水平，但低于后测试水平。
