Background: Nurses are at risk of injuries caused by sharp instruments in hospitals. The objective of this study was to investigate the frequency of injuries due to sharp instruments and its relevant factors among nurses of Imam Reza Hospital, Kermanshah, Iran.
Methods: This descriptive-analytic study was conducted on 258 nurses working at Imam Reza Hospital of Kermanshah, Iran, in 2013. The data collection measure was a researcher-made questionnaire, which its validity and reliability were verified. The obtained data were entered into SPSS, version 16 and were analyzed using the Chi-squared and ANOVA test at the significance level of P<0.05.
Results: According to the findings, 73.3%(n=191) of nurses were exposed to sharp injuries at workplace. About 41.8% of cases occurred during the first year of nursing. Major injuries were caused by needle-sticks (73.3%) and then IV catheter (42.4%). About 43.5% of the observed injuries occurred while trying to recap the needle-sticks. Also, 38.52% of injured nurses performed the tests after injury screening, while 48.7% did nothing after being injured.
Conclusion: With regard to the findings of this study, human and environmental factors are effective on these exposures and environmental factors are much effective than human factors. It seems necessary to train the personnel, observe general precautions, and change wrong behaviors namely needle re-capping.

Background: Viral hepatitis is one the main infections that health staff are faced with and nurses are at greater risk of the contracting this disease because of their exposure to patients. The current study was conducted to determine the hepatitis B vaccination coverage and its associated factors in nurses of Imam Reza (AS) Hospital in Kermanshah, Iran.

Methods: In this descriptive-analytic study, 258 nurses working in Imam Reza (AS) Hospital of Kermanshah were studied based on census records in 2012. Instrument for the data collection was a researcher-made questionnaire, which its validity and reliability were approved. Collected data were analyzed by the Chi-square and ANOVA tests using SPSS 16.

Results: Out of 258 nursing staff, 85.2% had completed vaccination, 3.9% had it once, and 10.9% had received two shots of vaccine. Among the most important barriers to vaccination mentioned by the participants were forgetting (57.2%), negligence (39.5%), and high workload (36.8%).

Conclusion: Given the relatively high coverage of vaccination in this study, to maintain the efficiency of nurses as well as reducing the cost of difficult treatment of hepatitis B, necessary facilities and education about the disease and its complications should be provided by the authorities for the full vaccination coverage at very low cost.
