Mass fatality incidents can overwhelm local, state and national resources quickly. Dental hygienists are widely distributed and have the potential to increase response teams' capacity. However, appropriate training is required. The literature is void of addressing this type of training for dental hygienists and scant in dentistry. Hence, the purpose of this study was to assess one facet of such training: Whether the use of multimedia is likely to enhance educational outcomes related to mass fatality training.
A randomized, double-blind, pre- and post-test design was used to evaluate the effectiveness of comparable educational modules for 2 groups: a control group (n=19) that received low media training and a treatment group (n=20) that received multimedia training. Participants were second-year, baccalaureate dental hygiene students. Study instruments included a multiple-choice examination, a clinical competency-based radiology lab scored via a standardized rubric, and an assessment of interest in mass fatality education as a specialty. ANOVA was used to analyze results.
Participants' pre- and post-test scores and clinical competency-based radiology lab scores increased following both educational approaches. Interest in mass fatality training also increased significantly for all participants (p=0.45). There was no significant difference in pre- and post-test multiple choice scores (p=0.6455), interest (p=0.9133) or overall competency-based radiology lab scores (p=0.997) between groups.
Various educational technique may be effective for mass fatality training. However, mass fatality training that incorporates multimedia is an appropriate avenue for training instruction. Continued research about multimedia's role in this specialty area is encouraged.
大规模死亡事件可能迅速耗尽地方、州和国家的资源。口腔卫生士分布广泛，有潜力增强应急小组的能力。然而，需要进行适当的培训。文献中缺乏针对口腔卫生士此类培训的内容，在牙科领域也很少见。因此，本研究的目的是评估此类培训的一个方面：使用多媒体是否可能提高与大规模死亡培训相关的教育成果。
采用随机、双盲、前后测试设计，评估两组可比教育模块的有效性：接受低媒体培训的对照组（n = 19）和接受多媒体培训的治疗组（n = 20）。参与者为牙科卫生专业二年级本科学生。研究工具包括多项选择题考试、通过标准化评分标准评分的基于临床能力的放射学实验室测试，以及对将大规模死亡教育作为专业领域的兴趣评估。采用方差分析来分析结果。
两种教育方法实施后，参与者的前后测试成绩以及基于临床能力的放射学实验室成绩均有所提高。所有参与者对大规模死亡培训的兴趣也显著增加（p = 0.45）。两组之间在前后测试多项选择题成绩（p = 0.6455）、兴趣（p = 0.9133）或基于整体能力的放射学实验室成绩（p = 0.997）方面没有显著差异。
各种教育技术可能对大规模死亡培训有效。然而，采用多媒体的大规模死亡培训是一种合适的培训指导途径。鼓励继续研究多媒体在这一专业领域的作用。
