To determine whether pediatricians accurately estimate the likelihood of gun ownership among their patients' families. Design. Self-administered, written surveys completed simultaneously by pediatricians and their patients' parents.
A total of 23 pediatric practices and hospital-based clinics in three cities in the United States.
A total of 66 pediatricians paired with 169 of their patients' parents.
Parent survey: ownership and storage of guns, willingness to admit gun ownership, and previous counseling by pediatrician. Pediatrician survey: estimated prevalence of gun ownership, likelihood of gun ownership by each participant family, and beliefs about firearm injury prevention counseling.
All parents who owned guns indicated they would acknowledge owning a gun if asked by their pediatricians. Of the participating families, 28% owned at least one gun; 39% of the homes with guns contained a gun that was unlocked, loaded, or both. Of the parents, 11% reported that their pediatrician had discussed firearm safety with them. Pediatricians' average estimate of the overall prevalence of gun ownership in their patient populations was 25%. When asked to predict the likelihood of gun ownership by the specific families in the study, pediatricians predicted a 0% likelihood of gun ownership for 33% of the families. Of those families, 30% reported owning at least one gun. Considering physician predictions of any likelihood of gun ownership >0% (1%-100%) to be a positive prediction and using parent reports as the gold standard, physician estimates of gun ownership were only 65% sensitive. Approximately half (55%) of the participating pediatricians believed that pediatricians should discuss gun safety with all families, and 98% believed that pediatricians should discuss gun safety with all gun-owning families.
Pediatricians believe that all families with guns should receive firearm safety counseling. However, pediatricians significantly underestimate the likelihood of gun ownership by specific families. Parents who own guns indicate that they would acknowledge gun ownership if their pediatrician asked about guns in the home. Therefore, rather than relying on assumptions about whether particular patients seem likely to be gun owners, pediatricians should ask all families whether they own guns.
确定儿科医生是否能准确估计其患者家庭拥有枪支的可能性。设计:儿科医生及其患者家长同时完成的自填式书面调查。
美国三个城市的23家儿科诊所和医院附属诊所。
66名儿科医生及其169名患者的家长。
家长调查问卷:枪支的拥有情况和存放方式、承认拥有枪支的意愿以及儿科医生先前的咨询。儿科医生调查问卷:估计的枪支拥有率、每个参与家庭拥有枪支的可能性以及对预防枪支伤害咨询的看法。
所有拥有枪支的家长表示,如果儿科医生询问,他们会承认拥有枪支。在参与调查的家庭中,28%至少拥有一支枪;在有枪的家庭中,39%的家中有未上锁、上膛或两者皆有的枪支。11%的家长报告称,他们的儿科医生曾与他们讨论过枪支安全问题。儿科医生对其患者群体中枪支拥有总体患病率的平均估计为25%。当被要求预测研究中特定家庭拥有枪支的可能性时,儿科医生预测33%的家庭拥有枪支的可能性为0%。在这些家庭中,30%报告至少拥有一支枪。将医生对任何枪支拥有可能性>0%(1%-100%)的预测视为阳性预测,并将家长报告作为金标准,医生对枪支拥有情况的估计敏感性仅为65%。约一半(55%)参与调查的儿科医生认为儿科医生应该与所有家庭讨论枪支安全问题,98%的医生认为儿科医生应该与所有拥有枪支的家庭讨论枪支安全问题。
儿科医生认为所有拥有枪支的家庭都应接受枪支安全咨询。然而,儿科医生显著低估了特定家庭拥有枪支的可能性。拥有枪支的家长表示,如果儿科医生询问家中是否有枪,他们会承认拥有枪支。因此,儿科医生不应依赖对特定患者是否可能是枪支拥有者的假设,而应询问所有家庭是否拥有枪支。
