ObjectiveTo investigate the incidence of sharp instrument injury of medical workers in a grade A tertiary hospital, analyze its influencing factors, and provide the scientific basis for hospital formulating effective prevention and control measures.

MethodsThe incidence rates of sharp instrument injury of 1 156 medical workers in a grade A tertiary hospital in 2015 were retrospectively analyzed using self-designed questionnaire.The correlations of the gender, nature of work, department, length of service, professional title, education and training with sharp instrument injuries in 1 071 valid questionnaires were analyzed.

ResultsThe sharp instrument injury in 284 cases were found in 2015, and the incidence rate of which was 26.5%.Except for gender, the differences of the incidence rates of sharp instrument injury among different nature of work, department, length of service, professional title, education and training medical workers were statistically significant(P < 0.01).The incidence rate of sharp instrument injury was set as the dependent variable, the statistically significant factors in the univariate analysis were set as the independent variable, and the results of univariate analysis showed that the department, length of service, professional title and training were the independent risk factors of sharp instrument injury(P < 0.05 to P < 0.01).

ConclusionsAccording to the influencing factors of sharp instrument injury, the knowledge training should be carried out, which can reduce the risk of sharp instrument injury.
