This study aimed to determine needlestick and sharps injuries (NSIs) incidence, identify associated risk factors, and describe reporting practices among dental instrument reprocessing personnel (DIRP) in China.
A nationwide cross-sectional study utilized stratified multistage random sampling across seven Chinese regions. Validated questionnaires were administered to 1942 DIRP from 130 dental facilities, collecting data on demographics, occupational conditions, NSI history, and reporting. Multivariate logistic regression identified independent NSI predictors.
The one-year NSI period incidence was 21.7% (n = 421/1942), with 28.5% of these individuals experiencing multiple injuries. Daily instrument handling volume demonstrated a dose-response relationship with NSI risk (aOR = 5.73, 95% CI: 3.17-10.34, for >1000 vs. ≤100 instruments). The NSI reporting rate was 87.2%. Primary barriers included demanding work schedules (51.9%) and perceived low exposure risk (40.7%). Post-training assessment was significantly associated with a reduced NSI risk (aOR = 0.65, 95% CI: 0.51-0.83). Both receiving NSI prevention training (aOR = 3.11) and undergoing post-training assessment (aOR = 2.47) significantly increased NSI reporting.
NSI prevalence among Chinese DIRP is substantial, strongly associated with instrument workload and work experience, and influenced by training assessment. Targeted interventions focusing on workload management, assessed training, and streamlined reporting are essential.
These findings highlight critical areas for improving DIRP safety. Implementing evidence-based workload limits, ensuring training includes competency assessment, and simplifying NSI reporting can reduce preventable injuries and enhance occupational health in dental settings globally.
本研究旨在确定针刺伤和锐器伤（NSIs）的发生率，识别相关风险因素，并描述中国牙科器械再处理人员（DIRP）的报告情况。
一项全国性横断面研究采用分层多阶段随机抽样，覆盖中国七个地区。对来自130家牙科机构的1942名DIRP进行了有效问卷调查，收集了人口统计学、职业状况、针刺伤史和报告情况等数据。多变量逻辑回归确定了针刺伤的独立预测因素。
一年期针刺伤发生率为21.7%（n = 421/1942），其中28.5%的人经历了多次伤害。每日器械处理量与针刺伤风险呈剂量反应关系（对于>1000件与≤100件器械，调整后比值比[aOR]=5.73，95%置信区间[CI]：3.17 - 10.34）。针刺伤报告率为87.2%。主要障碍包括工作安排紧张（51.9%）和认为暴露风险低（40.7%）。培训后评估与针刺伤风险降低显著相关（aOR = 0.65，95% CI：0.51 - 0.83）。接受针刺伤预防培训（aOR = 3.11）和接受培训后评估（aOR = 2.47）均显著增加了针刺伤报告。
中国DIRP中针刺伤患病率较高，与器械工作量和工作经验密切相关，并受培训评估影响。针对工作量管理、评估培训和简化报告的有针对性干预措施至关重要。
这些发现突出了改善DIRP安全性的关键领域。实施基于证据的工作量限制，确保培训包括能力评估，并简化针刺伤报告，可减少可预防的伤害，增强全球牙科环境中的职业健康。
