摘要目的:利用医院急诊科电子病历系统，分析动物致伤人群特征并总结受伤人群流行病学特点。方法:采用回顾性横断面研究方法，收集2022年10月8日至2023年10月30日浙江省立同德医院急诊科门诊登记系统记录的4类动物致伤（狗、猫、鼠类或其他动物）患者数据。研究变量包括患者人口学特征（性别、年龄、职业、住址等）、受伤特征（受伤日期、受伤地点、伤人动物种类、暴露等级、伤口部位、伤口数量、是否接种过疫苗等），对上述数据进行描述性统计和单变量分析。结果:2022年10月8日至2023年10月30日本院急诊共接诊1 266例动物致伤患者。研究期间，动物致伤患者的月度分布呈现明显的季节性趋势。全年各月均有动物致伤患者就诊，具体分布存在一定波动，其中夏秋季（7月至10月）病例相对较多，冬春季（12月至次年3月）病例相对较少，处于相对低发期。1 266例动物致伤患者中，女性680例（53.7%），男性586例（46.3%）；年龄27岁，范围11月龄～88岁；以职员/职工为主（占50.2%），其次为学生（21.6%）、工人（8.5%）、退休职工（3.6%）；大多数患者为本市居民（占90.6%），以无狂犬疫苗接种史患者居多（76.9%），仅3例（0.2%）患者在暴露前免疫。4类动物致伤患者中，以猫致伤（64.5%）和狗致伤（28.7%）为主，其次为鼠类致伤（4.9%）和其他动物致伤（1.9%）；受伤至就诊时间为0（0～40）d；多数患者的动物致伤暴露等级为Ⅲ级暴露（76.3%），其次为Ⅱ级暴露（23.2%），Ⅰ级暴露最少（0.5%）；伤口部位以上肢居多（72.1%），其次为下肢（21.2%），躯干最少（2.6%）；且伤口数量多为1处（75.8%），在家中受伤者占大多数（90.2%），伤口自行处理与门诊处理人数大致相当。按年龄和性别分层，可见4类动物致伤的高发年龄段均为18～39岁；在该年龄段，除鼠致伤外，其余动物致伤均为女性多于男性。结论:浙江杭州地区急诊科动物致伤事件中猫致伤比例较高。大多数患者无狂犬疫苗接种史和暴露前免疫；夏秋季病例较多，且高发期较为持久；急诊科动物致伤数据的使用提供了简便、可持续的动物致伤监测手段，是综合监测数据的新方式，可作为疾控监测体系的补充。

abstractsObjective:To analyze the characteristics of animal-related injuries and summarize the epidemiological features of the affected population using the hospital's emergency department electronic medical record system.Methods:A retrospective cross-sectional study was conducted, collecting data on animal-related injuries (dogs, cats, rodents, or other animals) as recorded in the outpatient registration system of the emergency department at Tongde Hospital of Zhejiang Province from October 8, 2022, to October 30, 2023. The study variables encompassed patient demographic characteristics (gender, age, occupation, residence, etc.), and injury characteristics (date and location of injury, type of animal inflicting the injury, level of exposure, wound site, number of wounds, vaccination history, etc.). Descriptive statistics and univariate analysis were performed on the collected data.Results:From October 8, 2022, to October 30, 2023, a total of 1 266 cases of animal bites were attended to in our hospital's emergency department. A distinct seasonal pattern was observed in the monthly distribution of animal bite patients, with a consistent presence throughout the year and notable fluctuations. There was a higher incidence during the summer and autumn (July to October), and a lower incidence during the winter and spring (December to the following March), marking a relatively quiescent period. The study included 680 female cases (53.7%) and 586 male cases (46.3%), with a median age of 27 years (range 11 months to 88 years). The majority of patients were clerks or workers (50.2%), followed by students (21.6%), laborers (8.5%), and retirees (3.6%). The majority of patients were local residents (90.6%), and the majority had no history of rabies vaccination (76.9%), with only 3 cases (0.2%) having pre-exposure immunization. Among the four types of animal bites, cat bites predominated (64.5%), followed by dog bites (28.7%), rodent bites (4.9%), and bites from other animals (1.9%). The time from injury to consultation was 0 (0-40) days. Most patients experienced a levelⅢ exposure (76.3%), with levelⅡ exposure being less common (23.2%), and levelⅠexposure being the least frequent (0.5%). The upper limbs were the most common site of injury (72.1%), followed by the lower limbs (21.2%), and the trunk was the least affected (2.6%). The majority of patients had a single wound (75.8%), and the majority of injuries occurred at home (90.2%). The number of patients who self-cleaned their wounds was comparable to those who sought outpatient treatment. When stratified by age and gender, the age of 18 to 39 years group was identified as the high-incidence demographic for all four types of animal bites. In this age group, except for injuries caused by mice, injuries caused by other animals were more common in females than males.Conclusions:The proportion of injuries caused by cats in animal-related incidents in the emergency department of Hangzhou, Zhejiang Province, is significantly high. The majority of patients lack a history of rabies vaccination and pre-exposure immunization. There is a higher incidence of cases during the summer and autumn months, with a prolonged high-incidence period. The utilization of emergency department data on animal injuries provides a convenient and sustainable method for monitoring animal bites, representing a novel approach to comprehensive surveillance data and serving as a valuable supplement to the existing disease control surveillance system.
