To obtain prospective evidence of whether industry support of continuing medical education (CME) affects perceptions of commercial bias in CME activities.
The authors analyzed information from the CME activity database (346 CME activities of numerous types; 95,429 participants in 2007) of a large, multispecialty academic medical center to determine whether a relationship existed among the degree of perceived bias, the type of CME activity, and the presence or absence of commercial support.
Participants per activity ranged from 1 to 3,080 (median: 276). When asked the yes/no question, "Overall, was this activity satisfactorily free from commercial bias?" 97.3% to 99.2% (mean: 98.4%) of participants answered "yes." In responding on a four-point scale to the request, "Please rate the degree to which this activity met the Accreditation Council for Continuing Medical Education requirement that CME activities must be free of commercial bias for or against a specific product," 95.8% to 99.3% (mean: 97.2%) of participants answered "excellent" or "good." When analyzed by type of funding relative to commercial support--none (149), single source (79), or multiple source (118)--activities were deemed to be free of commercial bias by 98% (95% CI: 97.3, 98.8), 98.5% (97.5, 99.5), and 98.3% (97.4, 99.1) of participants, respectively. None of the comparisons showed statistically significant differences.
This large, prospective analysis found no evidence that commercial support results in perceived bias in CME activities. Bias level seem quite low for all types of CME activities and is not significantly higher when commercial support is present.
获得关于产业界对继续医学教育（CME）支持是否会影响人们对 CME 活动商业偏见的看法的前瞻性证据。
作者分析了一家大型多专科学术医疗中心的 CME 活动数据库（2007 年有 346 种不同类型的 CME 活动，95429 名参与者）中的信息，以确定感知偏差的程度、CME 活动的类型以及商业支持的有无之间是否存在关系。
每个活动的参与者人数从 1 到 3080 人不等（中位数：276 人）。当被问及“总的来说，这项活动是否完全没有商业偏见？”这一是非题时，97.3%至 99.2%（平均值：98.4%）的参与者回答“是”。在对“请评价该活动在多大程度上符合继续教育认证委员会的要求，即 CME 活动必须对特定产品没有商业偏见”这一要求进行四点量表评估时，95.8%至 99.3%（平均值：97.2%）的参与者回答“优秀”或“良好”。根据相对于商业支持的资金来源（无、单一来源、多种来源）进行分析时，分别有 98%（95%置信区间：97.3%，98.8%）、98.5%（97.5%，99.5%）和 98.3%（97.4%，99.1%）的参与者认为这些活动没有商业偏见。没有一项比较显示出统计学上的显著差异。
这项大型前瞻性分析没有发现商业支持会导致 CME 活动中存在感知偏见的证据。所有类型的 CME 活动的偏差水平似乎都相当低，而且当存在商业支持时，偏差水平也没有显著增加。
