目的
确定指导者和及时的个性化反馈是否能提高医生在临床环境中使用GRATEFUL MED搜索MEDLINE的表现。
设计
随机对照试验。
设置
一所拥有300张床位的初级至三级护理教学医院。在6个主要临床服务的病房和诊所以及急诊室、重症监护室和新生儿重症监护室安装了计算机。
科目
来自内科、家庭医学科、外科、精神病学、儿科和妇产科的所有医生和实习医生，如果在研究期间做出患者护理决定至少8周，则均被纳入其中。
干预
所有参与者都接受了1小时的培训课程和1小时的个性化搜索，其中1名研究馆员。培训结束后，参与者被随机分配到一个没有接受进一步干预的对照组或一个干预组，其中每个人都选择了一位在MEDLINE搜索方面经验丰富的临床导师，并在前10次搜索中接受了研究馆员的个性化反馈，表明搜索质量并提供改进建议。反馈在搜索完成后的第一个星期寄出。
主要措施
按研究组、科室和培训水平、研究参与率和检索率列出的基线特征。
主要结果
392名合格医生中有308名参加了研究。参与率几乎达到80%，但各部门和培训水平有所不同。两组的基线特征以及首次检索的人数达到了极好的平衡。干预组参与者搜索MEDLINE的频率高于对照组（每月3.5次搜索，对照组每月2.5次，P = 0.046）。两组的第一次搜索的召回率和准确率明显低于图书馆员。研究数据的分析将于1991年9月完成。
结论
临床医生愿意在临床环境中进行MEDLINE的自助检索，但他们的精确度和召回率低于基线时受过培训的图书馆员。需要加强搜索技能，反馈和指导者的效果正在测试中。

OBJECTIVE
To determine if a preceptor and timely, individualized feedback improves the performance of physicians in searching MEDLINE using GRATEFUL MED in clinical settings.
DESIGN
Randomized controlled trial.
SETTING
A 300 bed primary to tertiary care teaching hospital. Computers were installed in wards and clinics of 6 major clinical services, and the emergency room, intensive care and neonatal intensive care units.
SUBJECTS
All physicians and physicians-in-training from the departments of Medicine, Family Medicine, Surgery, Psychiatry, Pediatrics, and Obstetrics and Gynecology were included if they made patient care decisions for at least 8 weeks during the study period.
INTERVENTION
All participants were given a 1-hour training class and 1 hour of individualized searching with 1 of the 2 study librarians. After training, participants were randomized to a control group who received no further intervention or to an intervention group in which each person chose a clinical preceptor experienced in MEDLINE searching and received individualized feedback by a study librarian on their first 10 searches, indicating search quality and providing suggestions for improvement. Feedback was mailed the first week day after the search was done.
MAIN MEASURES
Baseline characteristics by study group, department and level of training, study participation rates, and searching rates.
MAIN RESULTS
308 of 392 eligible physicians joined the study. Participation was almost 80% with some variation by department and level of training. Excellent balance in the baseline characteristics was achieved for the 2 groups, as well as for the number who did first searches. Intervention group participants searched MEDLINE more often than did controls (3.5 searches per month vs 2.5 per month for controls, P = 0.046). The recall and precision for first searches for both groups was significantly less than that of librarians. The analysis of study data will be completed by September 1991.
CONCLUSIONS
Clinicians are willing to do self-service searching of MEDLINE in clinical settings but their precision and recall are less than a trained librarian at baseline. Search skills enhancements are needed and the effect of feedback and preceptors is being tested.
