This study sought to determine the degree to which injury hospitalization, especially for assaultive injury, is a risk for subsequent hospitalization due to assault.
A New Zealand hospitalization database was used to perform a retrospective cohort study. Exposure was defined as an injury hospitalization, stratified into assaultive and nonassaultive mechanisms. Hospitalizations for an assault during a 12-month follow-up period were measured.
Individuals with a prior nonassaultive injury were 3.2 times more likely to be admitted for an assault than those with no injury admission (95% confidence interval [CI] = 2.7, 3.9). The relative risk associated with a prior assault was 39.5 (95% CI = 35.8, 43.5), and the subsequent admission rate did not vary significantly by sex, race, or marital or employment status. Among those readmitted for an assault, 70% were readmitted within 30 days of the initial hospitalization.
Prior injury is a risk for serious assault, and the risk is even greater if the injury is due to assault. Risk of readmission for assault is largely independent of demographic factors and greatest within 30 days of the initial assault.
本研究旨在确定因受伤住院，尤其是因攻击性伤害住院，会在多大程度上导致后续因攻击行为再次住院的风险。
使用新西兰住院数据库进行一项回顾性队列研究。暴露因素定义为因伤住院，并分为攻击性和非攻击性机制。测量在12个月随访期内因攻击行为导致的住院情况。
既往有非攻击性伤害的个体因攻击行为入院的可能性是未因伤入院个体的3.2倍（95%置信区间[CI]=2.7，3.9）。既往有攻击行为的相对风险为39.5（95%CI=35.8，43.5），后续入院率在性别、种族、婚姻或就业状况方面无显著差异。在因攻击行为再次入院的患者中，70%在首次住院后30天内再次入院。
既往受伤是遭受严重攻击的一个风险因素，如果受伤是由攻击行为导致，风险则更大。因攻击行为再次入院的风险在很大程度上与人口统计学因素无关，且在首次攻击后30天内风险最大。
