Dental interns are vulnerable to needlestick injuries (NSI). The objectives of this study were to examine the prevalence and characteristics of NSI exposures among dental interns during their first-year clinical training, assess risk factors, and evaluate reporting behaviours.
An online survey was conducted among dental interns of Class 2011-2017 at Peking University School and Hospital of Stomatology (PKUSS), China. The self-administrated questionnaire consisted of information on demographic profiles, NSI characteristics, and reporting practices. The outcomes were presented by descriptive statistics. A multivariate regression analysis was performed to assess NSI sources using a forward step-wise approach.
A total of 407 dental interns completed the survey (response rate 91.9%, 407/443), and 23.8% sustained at least one NSI. The mean number of NSIs per intern was 0.28 during the first clinical year. More occupation exposures occurred from October to December, between 13:00-15:00. Syringe needles were the most frequent sources, followed by dental burs, suture needles, and ultrasonic chips. The risk of peer-inflicted NSIs in the department of Paediatric Dentistry was 12.1 times higher than that in Oral Surgery (OR 12.1, 95% CI: 1.4-101.4). Appropriately 64.9% NSIs occurred when chairside assistants were absent. Compared to working alone, the risk of peer-inflicted NSIs was 32.3 times higher when providing chairside assistance (OR 32.3, 95% CI: 7.2-145.4). The left-hand index finger was the most commonly injured site. About 71.4% of exposures were reported in paperwork.
Dental interns are susceptible to NSIs during their first-year clinical training. Extra attention should be paid to syringe needles, dental burs, suture needles, and ultrasonic chips. The lack of chairside assistance is hazardous regarding NSIs. The training of chairside assistance of the first-year dental interns should be enhanced. First-year dental interns are required to increase their awareness of ignored behaviors related to NSI exposures.
牙科实习生容易发生针刺伤（NSI）。本研究的目的是调查北京大学口腔医学院（PKUSS）2011-2017 级牙科实习生在临床培训第一年的 NSI 暴露率、特征，评估危险因素，并评估报告行为。
采用在线问卷调查法对北京大学口腔医学院 2011-2017 级实习医生进行调查。问卷内容包括人口统计学特征、NSI 特征和报告情况。采用描述性统计方法分析结果。采用向前逐步法进行多变量回归分析，评估 NSI 来源。
共 407 名实习医生完成了调查（应答率 91.9%，407/443），23.8%的实习医生至少发生过 1 次 NSI。实习医生在第一年临床工作中平均每人发生 0.28 次 NSI。10 月至 12 月、13：00-15：00 之间职业暴露更为常见。发生针刺伤的锐器以注射器针头最为常见，其次是牙科手机、缝线针和超声洁牙机工作尖。儿牙科的实习医生发生同伴致伤性 NSI 的风险是口腔颌面外科的 12.1 倍（OR 12.1，95%CI：1.4-101.4）。当助手不在场时，64.9%的 NSI 发生。与单独工作相比，提供椅旁助手时发生同伴致伤性 NSI 的风险高 32.3 倍（OR 32.3，95%CI：7.2-145.4）。左手食指是最常见的受伤部位。约 71.4%的暴露发生在填写文书时。
牙科实习生在临床培训的第一年易发生 NSI。应特别注意注射器针头、牙科手机、缝线针和超声洁牙机工作尖。缺少助手时 NSI 风险增加。应加强对第一年牙科实习医生的椅旁助手培训。要求第一年牙科实习医生提高对忽视的与 NSI 暴露相关行为的认识。
