Unintentional home injuries are a leading cause of preventable death in young children. Safety education and equipment provision improve home safety practices, but their impact on injuries is less clear. Between 2009 and 2011, a national home safety equipment scheme was implemented in England (Safe At Home), targeting high-injury-rate areas and socioeconomically disadvantaged families with children under 5. This provided a 'natural experiment' for evaluating the scheme's impact on hospital admissions for unintentional injuries.
Controlled interrupted time series analysis of unintentional injury hospital admission rates in small areas (Lower Layer Super Output Areas (LSOAs)) in England where the scheme was implemented (intervention areas, n=9466) and matched with LSOAs in England and Wales where it was not implemented (control areas, n=9466), with subgroup analyses by density of equipment provision.
57 656 homes receiving safety equipment were included in the analysis. In the 2 years after the scheme ended, monthly admission rates declined in intervention areas (-0.33% (-0.47% to -0.18%)) but did not decline in control areas (0.04% (-0.11%-0.19%), p value for difference in trend=0.001). Greater reductions in admission rates were seen as equipment provision density increased. Effects were not maintained beyond 2 years after the scheme ended.
A national home safety equipment scheme was associated with a reduction in injury-related hospital admissions in children under 5 in the 2 years after the scheme ended. Providing a higher number of items of safety equipment appears to be more effective in reducing injury rates than providing fewer items.
非故意伤害是导致幼儿可预防死亡的主要原因。安全教育和设备提供可以改善家庭安全措施,但它们对伤害的影响不太明确。2009 年至 2011 年,英格兰实施了一项全国性家庭安全设备计划(Safe At Home),针对高伤害率地区和社会经济弱势家庭的 5 岁以下儿童。这为评估该计划对意外伤害住院的影响提供了一个“自然实验”。
对英格兰小地区(下层超级输出区(LSOA))意外伤害住院率进行控制中断时间序列分析,该计划在这些地区实施(干预地区,n=9466),并与英格兰和威尔士未实施该计划的 LSOA 进行匹配(对照地区,n=9466),并按设备提供密度进行亚组分析。
共有 57656 户家庭收到了安全设备。在计划结束后的 2 年内,干预地区的每月入院率下降(-0.33%(-0.47%至-0.18%)),但对照地区没有下降(0.04%(-0.11%至-0.19%)),趋势差异的 p 值=0.001)。随着设备供应密度的增加,入院率的下降幅度更大。在计划结束后 2 年以上,效果并未持续。
全国性家庭安全设备计划与计划结束后 2 年内 5 岁以下儿童与伤害相关的住院人数减少有关。提供更多数量的安全设备似乎比提供较少数量的设备更能有效降低伤害率。
