Objective: To determine prospectively whether parental receipt of injury pr
evention education is associated with new action limiting access to lethal
means and if so, what action was taken for which means. Method: Prospective
follow-up of 103 adults whose children made an emergency department visit
for mental health assessment or treatment. Record review assessed whether h
ospital staff provided injury prevention education. Logistic regression was
used to determine the likelihood of new caretaker action limiting access t
o the following potentially lethal means: firearms, alcohol, prescription m
edications, and over-the-counter medications. Results: Significant associat
ions were found between exposure to injury prevention education and action
to limit access (adjusted adds ratio = 3.6, 95% confidence interval = 1.1-1
2.1, p= .04). Five of 8 adults whose households contained firearms took new
action to limit access after injury prevention education, whereas none of
the 7 firearm-owning families who did not receive injury prevention educati
on took new action to limit firearm access. Similar patterns were seen for
other means. Adults more often chose to lock up rather than dispose of leth
al means. Conclusions: Injury prevention education should be provided to pa
rents during child/adolescent emergency department mental health-related vi
sits. Potential for violence prevention is real because parents do take new
action to limit access to lethal means when means restriction education is
provided.
