Infection control training for predoctoral dental students, dental hygiene students, and dental assistant students has assumed an important role in the educational process at our institution. As part of an ongoing review of the curriculum at our school, we conducted a retrospective analysis of reported percutaneous injuries during the years 1991 through 1994 to determine whether the increase in infection control training introduced at the school in 1990 has had an effect on our rate of percutaneous injuries.
The population examined in this retrospective study consisted of predoctoral and postdoctoral dental students, dental hygiene students, dental assistant students, and staff. The data for this retrospective study were obtained from annual reports of occupational exposures incurred by students and staff. These annual reports were generated by compiling and summarizing all percutaneous injury incident reports that were prepared for that year.
Our results indicate, that except for an increase in 1992, the total number and incidence of reported percutaneous injuries decreased from 1991 to 1994. Statistically significant decreases were seen in the total number of reported percutaneous injuries for all students, staff, and all groups combined. On the basis of data available for 1993 and 1994, the incidence of reported percutaneous injuries per 1000 procedures was fairly constant over these 2 years. Distribution of percutaneous injuries by source varied during the 4-year period.
As part of the outcomes assessment program at our institution, we conducted a retrospective study of reported percutaneous injuries from 1991 to 1994. This study demonstrated that, although the total number of injuries decreased significantly, the rates within certain individual groups remained unchanged. On the basis of this observation, increased emphasis in the prevention of percutaneous injuries through additional training is indicated for these groups.
针对牙科博士前学生、口腔卫生专业学生和牙科助理专业学生的感染控制培训，在我们院校的教育过程中发挥着重要作用。作为我校课程持续评估的一部分，我们对1991年至1994年期间报告的经皮损伤进行了回顾性分析，以确定1990年我校引入的感染控制培训增加是否对我们的经皮损伤发生率产生了影响。
这项回顾性研究调查的人群包括牙科博士前和博士后学生、口腔卫生专业学生、牙科助理专业学生以及工作人员。这项回顾性研究的数据来自学生和工作人员职业暴露的年度报告。这些年度报告是通过汇编和总结当年编写的所有经皮损伤事件报告生成的。
我们的结果表明，除了1992年有所增加外，1991年至1994年期间报告的经皮损伤总数和发生率有所下降。所有学生、工作人员以及所有组别的经皮损伤报告总数均出现了统计学上的显著下降。根据1993年和1994年可得的数据，这两年每1000例操作中经皮损伤的发生率相当稳定。在这4年期间，经皮损伤的来源分布有所不同。
作为我校结果评估项目的一部分，我们对1991年至1994年期间报告的经皮损伤进行了回顾性研究。这项研究表明，尽管损伤总数显著下降，但某些个体组别的发生率保持不变。基于这一观察结果，表明需要对这些组加强培训以预防经皮损伤。
