Evaluation of a child safety program based on the WHO Safe Community model

摘要

Objectives: To evaluate the outcome of the World Health Organization (WHO) Safe Community model with respect to child injuries. Study design: A population based quasiexperimental design was used. Cross sectional pre-implementation and post-implementation data were collected in intervention (Motala municipality) and control (Mjölby municipality) areas, both in Östergötland county, Sweden. Results: The total relative risk of child injury in the intervention community decreased more (odds ratio 0.74; 95% confidence interval (CI) 0.68 to 0.81) than in a control community exposed only to national level injury prevention programs (0.93; 95% CI 0.82 to 1.05). The relative risk of moderately (abbreviated injury scale (AIS) 2) severe injury in the study area was reduced to almost a half (odds ratio 0.49; 95% CI 0.41 to 0.57), whereas the risk of minor (AIS 1) injuries decreased only slightly (odds ratio 0.89; 95% CI 0.80 to 0.99). The risk of severe or fatal (AIS 3–6) injuries remained constant. Conclusions: After introduction of an injury prevention program based on the WHO Safe Community model, the relative risk for child injury in the intervention community decreased significantly more than in a control community exposed only to national injury prevention programs.
