evaluation of preventive interventions in reporting needle stick injuries among health care workers

background and objective: needle stick injuries (nsis) are a common potential risk for healthcare workers. the aim of this study was to evaluate preventive interventions against needle stick injury incidents among hcws.   methods: seven hospitals in the iranian chaharmahal-va-bakhtiari province were surveyed between march 2008 to march 2013. data of the needle stick injuries of healthcare workers was extracted from the hospital documentations. chi-square test and logistic regression were used for analyzing the data.   findings: a total of 571 exposures (30.9%) to blood and other infected fluids were recorded. three measures of the preventive interventions against occupational exposures were found to be independently associated with interval reporting time less than 72 hours; a positive history of training courses passed [p=0. 012, or=0. 440, 95%ci: 0.233-0.832], standard infection control procedures after needle stick injury [p=0. 000, or=4. 905, 95%cl: 2.777 –8.663], wearing personal protective equipment [p=0. 000, or=9. 313, 95%cl: 4.142 – 20.940].   conclusions: personnel protective equipment, training of employees, and use of standard infection control procedures after nsi incident are both essential and effective in preventing viral transmission of blood-borne diseases among healthcare workers.
