Background The home is a leading location of injury for young children.
Objective Test the efficacy of home safety device installation on medically-attended injury.
Methods Of 8878 screened prenatal patients, 1263 (14%) were eligible and 468 (37%) agreed to participate. 355 children were born and randomly assigned to experimental (n=181) or control (n=174) groups. The mean number and density (no. per area) of hazards were assessed at home visits by trained research assistants using a validated survey. Medically-attended visits were measured by telephone survey. Two intention-to-treat analyses were conducted on (1) total injury rates and (2) on injuries deemed, a priori, preventable by installation of devices. Rates were calculated over 24 months using Poisson regression and generalised estimating equations.
Results The mean age of children at intervention was 6 months. Injury hazards were significantly reduced from baseline to 12 months in intervention but not control homes (p<0.005). The mean number (p<0.02) but not density (p=0.44) of hazards was also reduced at 24 months compared to controls. There was no significant difference in the rate of all medically-attended injuries for intervention compared to control group children, 14.3 (95% CI 9.7 to 21.1) versus 20.8 (95% CI 14.4 to 29.9) per 100 child-years (p=0.17) respectively; but there was a significant reduction in preventable medically attended injuries among intervention compared to control group children, 2.3 (95% CI 1.0 to 5.5) versus 7.7 (95% CI 4.2 to 14.2) per 100 child-years, respectively (p=0.026).
Conclusions An intervention to reduce exposure to injury hazards in homes of young children led to a 70% reduction in injury. |
