A long-term study of sharps injuries among health care workers in Japan.
BACKGROUND
The risk of transmission of occupational blood-borne infection is a serious problem for health care workers (HCWs) in Japan. Although the Japanese version of Exposure Prevention Information Network (EPINet) was introduced in 1997, no published data in the clinical setting have been available yet.


OBJECTIVE
To examine the epidemiology of occupational sharps injuries of HCWs in a university hospital using EPINet and to analyze the trends and changes in epidemiologic characteristics of needlestick injuries in a detailed situation.


METHODS
The HCWs were requested to report sharps injury incidents to the Infection Control Nurse when the incidents occurred. Those who were involved in the incidents were required to personally complete an EPINET form.


RESULTS
A total of 259 cases of sharps injuries occurred during the 7-year period. Registered nurses accounted for 72.2% of the cases, constituting the largest group of the HCWs. The incidents occurred most frequently in the hospital wards. Thirty-three cases (55.9%) of the injuries with syringe-needle units occurred "after use before disposal," whereas 34 cases (73.9%) of the injuries with suture needles occurred "during use of device." More than half of the injuries with a winged steel needle occurred despite the protective mechanism.


CONCLUSIONS
There was no apparent difference in the characteristics of the subjects compared with other reports. The circumstances of the injuries varied with the kinds of instruments. This fact may provide useful information for planning measures to sharps injuries.


CONCLUSIONS
With the problem of underreporting aside, a detailed study, such as ours, comprising by job category and by kind of instrument or the like would provide more useful and effective information in terms of sharps injury prevention.
