[Investigation on the relation between hepatitis B virus knowledge and needle-stick injury of hospital personnel].

The purposes of this study are: (1) to understand the knowledge of Hepatitis B virus known by hospital personnel. (2) to investigate the injury caused by accidental needle stick and its frequency. (3) to identify those personnel and job activities at high risk of needlestick injuries, to assess current medical management of these injuries in our hospital, and also to develop rational guidelines for prevention, based on the findings. 510 effective questionnaires were collected and analyzed by SPSS analytical system. The result of the present study showed that 77.1% hospital personnel had been experienced by needlestick injury. Most injuries occurred during recapping the needle after use and disposal of used needle. 92.7% hospital personnel felt that hospital should provide all the expense needed for Hepatitis B virus immunoglobulin while needle-stick injuries happened within the hospital. 86.3% of them felt that hospital should establish a special committee to evaluate and manage all the needle-stick injuries events. This study also showed that hospital personnel who have been working less than five years and their age between 21-30 can pay more attention to this kind of event. Dietitian and doctor got higher score in this study. Hospital personnel who were infected by Hepatitis B virus scored higher than uninfected one. In conclusion, we recommend not recapping used needles and making widely available and promoting use of an efficient needle disposal system. And we hope that those who have never been infected by Hepatitis B virus should accept vaccination as soon as possible.
