Concerns have been raised about bias in commercially supported continuing medical education (CME) activities, although the data are sparse about whether such bias exists, or if so, its extent.
Postactivity CME evaluation surveys were analyzed to quantitate reporting rates of bias, overall and by funding source.
5Of 1,621,647 physicians who participated in online CME activities, 1,064,642 (65.7%) completed the evaluation surveys and 5.9% reported no opinion. The affirmative rates of physician perception of bias were 0.63% overall, a weighted average of 0.84% for activities developed with and 0.48% for those developed without commercial support, a difference of 0.36% (P <.001, 95% confidence interval, 0.33-0.39). Among the subgroup who strongly disagreed that there is no bias, the difference between commercial (0.17%) and noncommercial (0.11%) funding was 0.06% (P <.001, 95% confidence interval, 0.05-0.08, P <.05), smaller than the overall difference.
These data demonstrate that about 93% of physician participants affirmatively claim to perceive no commercial bias following online CME activities, over 99% if no opinion is included, overall and regardless of funding source.
人们对商业支持的继续医学教育（CME）活动中的偏见表示担忧，尽管关于这种偏见是否存在以及如果存在其程度如何的数据很少。
对活动后的CME评估调查进行分析，以量化偏见的报告率，包括总体报告率和按资金来源分类的报告率。
在参与在线CME活动的1,621,647名医生中，1,064,642名（65.7%）完成了评估调查，5.9%的人表示没有意见。医生对偏见的肯定感知率总体为0.63%，由商业支持开展的活动加权平均为0.84%，无商业支持开展的活动为0.48%，差异为0.36%（P<.001，95%置信区间，0.33 - 0.39）。在强烈不同意不存在偏见的亚组中，商业（0.17%）和非商业（0.11%）资金之间的差异为0.06%（P<.001，95%置信区间，0.05 - 0.08，P<.05），小于总体差异。
这些数据表明，约93%的医生参与者在在线CME活动后肯定地声称没有察觉到商业偏见，如果将没有意见的情况包括在内，则超过99%，总体而言且无论资金来源如何。
