To estimate, using a novel interactive voice response (IVR) survey, the incidence of self-reported violence-related experiences of adolescent assault-injured patients in the weeks after discharge from the emergency department (ED).
In an urban ED, a prospective cohort study with 8-week follow-up IVR survey either weekly, bi-weekly, or monthly after discharge was conducted with patients aged 12–19 years presenting with assault-related injuries. Survival analysis methods were used to estimate cumulative risks of self-reported violence experienced within 4 and 8 weeks.
A total of 95 patients were enrolled; 42 (44.2%) reported to the IVR survey. As a result of the ED index event, an estimated 18.2% (confidence interval [CI]=9.1%–34.6%) reported being assaulted (no weapon), 2.9% (CI = .4%–19.1%) had been shot or stabbed, 20.7% (CI =10.9%–37.3%) had assaulted someone else (no weapon), and 2.9% (CI=.4%–19.1%) shot or stabbed someone else. Additionally, 54.6% (CI=39.6%–70.9%) had avoided going certain places, 47.0% (CI = 32.5%–64.1%) considered retaliating, 38.1% (CI =24.3%–56.3%) had been threatened, and 27.0% (CI =15.4%–44.6%) had carried a weapon. Most outcome occurrences happened within 4 weeks. There was evidence that intent to retaliate when asked at baseline was associated with an elevated risk of several outcomes.
The risk for subsequent violence among assault-injured adolescent ED patients appears high within weeks of discharge.
使用新型交互式语音应答（IVR）调查评估青少年因袭击受伤后从急诊科（ED）出院后数周内自我报告的暴力相关经历的发生率。
在城市 ED 中，对 12-19 岁因与袭击有关的伤害就诊的患者进行了一项前瞻性队列研究，在出院后进行为期 8 周的 IVR 调查随访。使用生存分析方法估计在 4 周和 8 周内自我报告的暴力经历的累积风险。
共纳入 95 名患者；42 名（44.2%）接受了 IVR 调查。由于 ED 首发事件，估计有 18.2%（置信区间[CI]=9.1%–34.6%）报告遭受过无武器的袭击，2.9%（CI =.4%–19.1%）被枪击或刺伤，20.7%（CI =10.9%–37.3%）袭击过他人（无武器），2.9%（CI=.4%–19.1%）枪击或刺伤过他人。此外，54.6%（CI=39.6%–70.9%）避免去某些地方，47.0%（CI = 32.5%–64.1%）考虑报复，38.1%（CI =24.3%–56.3%）受到威胁，27.0%（CI =15.4%–44.6%）携带武器。大多数结局发生在 4 周内。有证据表明，在基线时询问的报复意图与几种结局的风险增加相关。
在出院后数周内，受伤的青少年 ED 患者发生后续暴力的风险似乎很高。
