To evaluate the effect of an educational intervention on parental knowledge of choking hazards and prevention.
A quasi experimental study was performed utilizing an internet based educational video intervention for parents with a child 6 months to 4 years old presenting to a Pediatric Otolaryngology clinic at a Level 1 pediatric hospital. Following the clinic visit, participants were sent a choking video (intervention) or general safety video (control) with a pretest and posttest knowledge survey (via email). An additional posttest knowledge survey was sent 30 days later as a surrogate measure for knowledge retained over time. Frequencies, chi square test, Independent t-test and McNemar's test were used for statistical analyses.
202 participants viewed the video and completed both the pretest and immediate posttest knowledge survey. Average change in total knowledge scores from the pretest to immediate posttest was statistically significant between the intervention (μ = 1.88, σ = 1.20) and control group (μ = 0.14, σ = 1.05); t (200) = -10.99, P < .001. This finding was consistent when assessing change from the pretest to 30 day posttest between the intervention (μ = 1.41, σ = 1.32) and control group (μ = 0.17, σ = 1.41); t (118) = -4.95, P < .001. A majority of the knowledge questions (5 of 7) showed a significant change in score from the pretest to immediate posttest (P = .001-.027). Additional analyses revealed accuracy on 4 of 7 knowledge questions significantly changed from the pretest to 30 day later posttest (P < .001- .002).
The brief educational video overall improved parental knowledge of choking hazards and prevention immediately after the video and 30 days later. Importantly, improved parental knowledge may decrease rates of choking among children.
评估一项教育干预措施对家长关于窒息风险及预防知识的影响。
采用准实验研究，对一家一级儿科医院儿科耳鼻喉科门诊就诊的6个月至4岁儿童的家长，利用基于互联网的教育视频进行干预。门诊就诊后，通过电子邮件向参与者发送窒息视频（干预组）或一般安全视频（对照组），并进行知识预测试和后测试。30天后再发送一次后测试知识调查问卷，作为随时间推移知识留存情况的替代指标。采用频率分析、卡方检验、独立t检验和麦克尼马尔检验进行统计分析。
202名参与者观看了视频并完成了知识预测试和即时后测试。干预组（μ = 1.88，σ = 1.20）和对照组（μ = 0.14，σ = 1.05）从预测试到即时后测试的总知识得分平均变化具有统计学意义；t（200）= -10.99，P <.001。在评估干预组（μ = 1.41，σ = 1.32）和对照组（μ = 0.17，σ = 1.41）从预测试到30天后测试的变化时，这一结果是一致的；t（118）= -4.95，P <.001。大多数知识问题（7个中的5个）从预测试到即时后测试的得分有显著变化（P =.001-.027）。进一步分析显示，7个知识问题中的4个从预测试到30天后测试的准确性有显著变化（P <.001-.002）。
简短的教育视频在视频播放后即时以及30天后总体上提高了家长关于窒息风险及预防的知识。重要的是，家长知识的提高可能会降低儿童窒息的发生率。
