A nudge corresponds to any procedure that influences choice architecture, without using persuasion or financial incentives. Nudges are effective in increasing vaccination with heterogeneous levels of acceptability.
To evaluate the effectiveness and acceptability of a nudge promoting influenza vaccination for general practice trainees, also called residents.
The hypothesis was that a reminder would be efficient and accepted and that prior exposure to a nudge increases its acceptability. Residents were randomly divided into three parallel experimental arms: a nudge group, a no-nudge group and a control group in order to evaluate the Hawthorne effect. The nudge consisted of providing a paper form for the free delivery of the vaccine and contacts for occupational health services.
The analysis included 161 residents. There was a strong consensus among the residents that it is very acceptable to nudge their peers and patients. Acceptability was better with residents exposed to the nudge and with residents included in step 1 (Hawthorne effect). The nudge did not increase vaccination coverage.
The failure of this nudge highlights the importance of matching an intervention to the population's needs. The experimental approach is innovative in this context and deserves further attention.

推动对应于任何影响选择架构的程序，而不使用说服或经济激励。推动在提高疫苗接种的接受程度方面具有不同的有效性。
评估针对一般实践培训生（也称为居民）的推动流感疫苗接种的推动措施的有效性和可接受性。
假设提醒会是有效的且被接受的，并且事先接触推动会增加其可接受性。居民被随机分为三个平行的实验组：推动组、无推动组和对照组，以评估霍桑效应。推动措施包括提供一份免费提供疫苗和职业健康服务联系的纸质表格。
分析包括 161 名居民。居民强烈认为推动他们的同行和患者是非常可接受的。在接触到推动的居民和在第 1 步（霍桑效应）中包含的居民中，可接受性更好。推动并没有增加疫苗接种覆盖率。
这次推动的失败凸显了将干预措施与人群需求相匹配的重要性。这种实验方法在这种情况下具有创新性，值得进一步关注。
