To identify self-perceived problems in managing science information needs of U.S. primary practitioners and their opinion leaders.
A two-stage random sample of the American Medical Association's "Masterlist of Physicians" to identify 625 office-based physicians, including general practice, family practice, internal medicine, obstetrics and gynecology, and pediatrics, and 100 physician opinion leaders.
A formal telephone survey was completed for 79% of practitioners and 90% of opinion leaders sampled, using a pretested instrument applied by trained telephone surveyors.
Both practitioners and opinion leaders claimed that published reviews were the most useful means of identifying their information needs. When asked about use of six recent clinical advances, that is, "markers," for example, hemoglobin-A1C for diabetic control, as many as one fifth to one half were not using or were not aware of such an advance. Less than 1 in 3 practitioners personally searched the literature when information was needed; 2 in 3 claimed literature volume was unmanageable; 9 of 10 practitioners and opinion leaders assessed the scientific value of literature obtained, primarily from their own experience, with less than 1 in 10 contacting research methods specialists. Respondents suggested various innovations to better manage their science information needs in the future.
Primary practitioners require substantial help in meeting current science information needs. Increase in such resources as "validated reviews" or "expert networks" might help meet these needs.
识别美国基层医疗从业者及其意见领袖在管理科学信息需求方面自我感知到的问题。
从美国医学协会的“医师总名单”中进行两阶段随机抽样,以确定625名门诊医生,包括全科、家庭医学、内科、妇产科和儿科医生,以及100名医师意见领袖。
对79%的抽样从业者和90%的意见领袖完成了一项正式的电话调查,使用经过预测试的工具,由经过培训的电话调查员进行。
从业者和意见领袖均声称,发表的综述是识别他们信息需求的最有用手段。当被问及六项近期临床进展(即“标志物”)的使用情况时,例如用于糖尿病控制的糖化血红蛋白A1C,多达五分之一到二分之一的人未使用或未意识到此类进展。不到三分之一的从业者在需要信息时亲自检索文献;三分之二的人声称文献数量难以管理;十分之九的从业者和意见领袖主要根据自己的经验评估所获取文献的科学价值,只有不到十分之一的人联系研究方法专家。受访者提出了各种创新建议,以便在未来更好地管理他们的科学信息需求。
基层医疗从业者在满足当前科学信息需求方面需要大量帮助。增加诸如“经过验证的综述”或“专家网络”等资源可能有助于满足这些需求。
