Parents are likely to encounter a different type of question during their children’s health visits at Duke University Health System’s pediatric clinics these days: Do you need a gun lock? As part of a joint effort by Durham County and Duke, pediatricians are talking to parents not only about the safety of guns in families’ homes but also about safeguards in places where children visit. “It involves not only asking, ‘Do you have a gun in the house where the child lives?’, but also, ‘What about family members and friends?’ and ‘What about other households where the children may visit or stay during the weekend?’” said Dr. Sara Robert a Duke pediatrician and professor.
