Abstract

OBJECTIVE

To test the urban myth that surplus chocolate Easter Bunnies are re-packaged as Santa Clauses for the following Christmas holiday season.

DESIGN

Prospective radiographic cohort study of seasonal chocolate figurines, supplemented by anonymous 5-item questionnaire survey of belief in the re-wrapping myth (Generic Risk Items Noted by Chocolate consumers in Health care settings; GRINCH).

SETTING

Two tertiary referral trauma centres in Germany (Berlin and Duisburg).

PARTICIPANTS

Eighteen chocolate Easter Bunnies and 15 chocolate Santa Clauses from different manufacturers purchased during 2020; 502 randomly selected people passing through the entrance halls of the two hospitals during 16 September - 12 October 2020.

MAIN OUTCOME MEASURES

Whole body computed tomography (WBCT) images of chocolate Easter Bunnies and Santa Clauses assessed by four independent, board-certified radiologists using a visual contour resemblance scale (CRS); survey participants' views on statements related to the re-wrapping myth.

RESULTS

Expert examiners clearly distinguished the WBCT images of chocolate Easter Bunnies and Santa Clauses; the mean difference in CRS was 84.2 points (95% CI, 78.5-90.0 points), with excellent inter-observer agreement (mean intra-class correlation coefficient, 0.99; 95% CI, 0.99-1.00). A total of 214 survey participants (43%) disagreed and 145 (29%) agreed with the proposition that seasonal chocolate figurines are re-packaged and re-sold the following season.

CONCLUSION

Although about one-third of our survey respondents did not rule out the possibility of seasonal sweets being re-used, WBCT imaging found no similarity between chocolate foil-wrapped Easter and Christmas figurines, providing solid evidence against this urban myth. Chocolate Santa Clauses are unlikely to pose a significant threat to hospital food hygiene requirements.

摘要

目的

检验有关过剩巧克力复活节兔子被重新包装成圣诞老人以供应下一个圣诞节的都市传说。

设计

对季节性巧克力小雕像进行前瞻性放射队列研究，并补充对重新包装传说（巧克力消费者在医疗保健环境中注意到的通用风险项目；GRINCH）的匿名五项问卷调查。

地点

德国的两个三级转诊创伤中心（柏林和杜伊斯堡）。

参与者

购买于 2020 年的 18 个不同制造商的巧克力复活节兔子和 15 个巧克力圣诞老人；2020 年 9 月 16 日至 10 月 12 日期间，502 名随机穿过这两家医院入口大厅的人。

主要观察指标

由四位独立的、有委员会认证的放射科医生使用视觉轮廓相似性量表（CRS）对巧克力复活节兔子和圣诞老人的全身计算机断层扫描（WBCT）图像进行评估；调查参与者对与重新包装传说相关的陈述的看法。

结果

专家审查员清楚地区分了巧克力复活节兔子和圣诞老人的 WBCT 图像；CRS 的平均差异为 84.2 分（95%置信区间，78.5-90.0 分），观察者间一致性极好（平均组内相关系数，0.99；95%置信区间，0.99-1.00）。共有 214 名调查参与者（43%）不同意，145 名（29%）同意季节性巧克力小雕像被重新包装并在下一个季节重新销售的说法。
