Abstract

INTRODUCTION

The growing interest in incorporating prevention into emergency health care make it timely to examine the use of computer technology to efficiently deliver effective education in this setting.

STUDY DESIGN

This RCT compared results from an intervention group (n=367) that received child passenger safety information, to an attention-matched control (n=375). A baseline survey and two follow-up surveys at 3 and 6 months were conducted.

SETTING/PARTICIPANTS: Data were collected from June 2014 to September 2016 from a sample of parents with children aged 4-7 years recruited from a pediatric emergency department in an East Coast urban area and one in a Midwest semi-rural area.

INTERVENTION

A theory-based, stage-tailored educational program, Safety in Seconds v2.0, delivered on a mobile app.

MAIN OUTCOME MEASURES

Four car seat behaviors: (1) having the correct restraint for the child's age and weight; (2) having the child ride in the backseat all the time; (3) buckling up the child all the time; and (4) having the child's restraint inspected by a child passenger safety technician.

RESULTS

At 3 months, adjusting for baseline behaviors and attrition, the odds of reporting the correct behavior by the intervention group relative to the control group was 2.07 (p<0.01) for using the correct car seat; 2.37 (p<0.05) times for having the child ride in the back seat; 1.04 (nonsignificant) for riding buckled up all the time; and 1.99 (p<0.01) times for having the car seat inspected. At 6 months, there were statistically significant effects for reporting use of the correct car seat (OR=1.84, p<0.01) and having the car seat inspected (OR=1.73, p<0.01).

CONCLUSIONS

Mobile apps hold promise for reaching large populations with individually tailored child passenger safety education.

TRIAL REGISTRATION

摘要

简介

将预防措施纳入紧急医疗保健的兴趣日益浓厚，因此及时研究利用计算机技术在这种环境下高效提供有效教育。

研究设计

这项 RCT 将接受儿童乘客安全信息的干预组（n=367）与注意力匹配的对照组（n=375）的结果进行比较。在 2014 年 6 月至 2016 年 9 月期间，从东海岸城市和中西部半农村地区的儿科急诊部门招募了 4-7 岁儿童的父母样本中收集数据。

干预措施

基于理论的、阶段定制的教育计划，Seconds v2.0 安全版，通过移动应用程序提供。

主要观察指标

四项汽车座椅行为：（1）为孩子的年龄和体重选择正确的约束装置；（2）让孩子一直坐在后座；（3）一直系好孩子的安全带；（4）让儿童乘客安全技术人员检查儿童的约束装置。

结果

在 3 个月时，调整基线行为和流失情况，干预组相对于对照组报告正确行为的可能性为 2.07（p<0.01），正确使用汽车座椅；2.37（p<0.05）倍，让孩子坐在后座；1.04（无显著差异），一直系好安全带；1.99（p<0.01）倍，让汽车座椅接受检查。在 6 个月时，报告正确使用汽车座椅（OR=1.84，p<0.01）和检查汽车座椅（OR=1.73，p<0.01）有统计学意义。
