Impact of the national home safety equipment scheme ‘Safe At Home’ on hospital admissions for unintentional injury in children under 5: a controlled interrupted time series analysis

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
