Objective To understand the incidence of sharp injury among stomatological majored interns from a vocational college, explore relevant risk factors, and provide scientific basis for developing protective measures against medical services related sharp injuries.
Methods A retrospective questionnaire survey was conducted in April 2013 among stomatological students who were admitted to the college in 2010.
Results During the 10-month internship, 76.24% of the interns reported sharp injuries. There were 1 490 episodes of sharp injuries, with an average of about 3.51 times per person. The injuries were mostly caused by syringe needles, reamers, and files, during oral treatment, and in oral surgery outpatient service. The results of multiple linear regression models showed that lack of protection knowledge, no pre-job training, unskilled, being nervous, or absent-minded during working process showed an elevated possibility to be involved to sharp injury(β were 1.02, 0.77, 0.56, 0.31, and 0.74, respectively, all P< 0.05).
Conclusion A high incidence of sharp injury is found among stomatological interns. It is recommended to establish a sound occupational protection education system for stomatological students to minimize the occurrence of sharp injuries.
