Purpose: The purpose of this study was to identify the factors related to blood-borne infection prevention behaviors based on the risk perception of the health belief model among operating room nurses. Risk perception factors included perceived susceptibility, barriers, benefits, and perceived severity. Methods: Data were collected from 121 operating room nurses working in four different hospitals in Daejeon and Seoul from June 30 to May 11, 2016. Results: The mean age was 31.2 years, and the average years of clinical experience in operating room was 7.9 years. The mean score of knowledge was 13.15. The mean score of perceived susceptibility, barrier, benefit, and perceived severity were 3.76, 3.70, 3.95, and 4.64, respectively. Blood-borne infection prevention behaviors had positive correlation with perceived benefits (p=.010), but negative correlation with sensitivity (p=.009) and barrier (p=.012). The hierarchical regression model on infection prevention behavior was statistically significant (F=4.85, p<.001). The sixteen percent of variance in behavior was explained by age (${\beta}=.18$, p=.038), perceived benefit (${\beta}=.20$, p=.030), perceived susceptibility (${\beta}=-.25$, p=.005), and perceived barrier (${\beta}=-.18$, p=.042). Conclusion: In order to increase infection prevention behaviors among operating room nurses, there is a need for developing specific education program focusing on appropriate management of equipment, instruments, and environment in operating room. In addition, support from the hospital organization level need to be provided as well.

Purpose: To develop a web-based program on blood-borne infection control and to examine the effect of the newly developed program on perceived threat of diseases, knowledge, preventive health behaviors for blood-borne infections, and incidence rates of accidental needle sticks and other sharp object injuries in nurses. Methods: The program was developed through the processes of analysis, design, development, implementation, and evaluation. The research design involved a nonequivalent control group for pretest and posttest experiments. The setting was a 745-bed general hospital located in Korea. Results: The program was designed and developed after consulting previous studies. After development of the program was completed, it was evaluated and revised by a panel of experts. The total score for perceived threat of diseases, knowledge, preventive health behaviors in the experimental group was significantly higher compared to the control group (p<.05). The incidence rates for needle sticks and other sharp object injuries in the experimental group were significantly lower compared to the control group (p<.05). Conclusion: Application of a Web-based, blood-borne infection control program is effective, and can be expanded to other healthcare workers who also have a high risk of blood-borne infections.

Purpose: This study was conducted to investigate the cognition level and the performance level of universal precautions on blood-borne infections and to analyze related-factors on the performance level for universal precautions among the nurses. Method: A total of 166 nurses participated in the survey. We performed multiple linear regression to assess the related-factors on the performance level for universal precautions. Result: The mean scores of cognition and performance level for universal precautions were 65.61(${\pm}8.74$) and 53.98(${\pm}8.42$) respectively. The mean score of the cognition level was significantly lower than the performance level in all items. The cognition level was associated with the working field. The performance level was highest for nurses working over 36 years, nurses in university hospitals, and nurses in the operating room. The cognitive level for universal precautions, education level, exposure to blood-borne infection, family's income, and marital status significantly predicted the performance level for universal precautions in the multiple linear regression model (Adjusted $R^2=0.42$). Conclusion: The cognition level for universal precautions is the strongest predictor on the performance level for universal precautions. An integrated approach should incorporate training experiences to improve cognition and perception of risk on universal precautions for preventing blood-borne infections.

Purpose: Exposure to blood and body fluids represents a significant occupational risk for nurses. This study was done to identify the level of knowledge of and compliance with blood-borne pathogen prevention of hospital nurses according to clinical experience, and to identify factors affecting compliance with blood-borne pathogen prevention. Methods: A descriptive correlational study was conducted in which self-reported knowledge of and compliance with blood-borne pathogen prevention was assessed. The relationships between variables were examined. Registered nurses who were employed (n=345) were surveyed. Data were analyzed using, t-test, ANOVA, Pearson correlation, and multiple linear regression. Results: Nurses with more than 5 years experience had greater knowledge of blood-borne pathogen prevention than nurses with less than 5 years experience. However, there was no significant difference in compliance with blood-borne pathogen prevention between the two groups. No significant correlation was found between knowledge and compliance with blood-borne pathogen prevention according to experience standards. In nurses with less than 5 years experience, gender, age, reported exposure to a blood-borne pathogen, and compliance with principles of prevention had a significant impact on compliance with blood-borne pathogen prevention. For nurses with more than 5 years experience, reporting after exposure to blood-borne pathogen was a contributing factor to compliance with blood-borne pathogen prevention. Conclusion: The study results show that to improve the implementation of preventive measures against blood-borne pathogens different strategies are needed, depending on clinical experience of the nurses.

Purpose: The study was done to examine hemodialysis unit nurses' knowledge on blood-borne infections, compliance and barriers to control and predictors of compliance. Methods: A descriptive correlational study was conducted with 122 nurses from hemodialysis units. Data were collected using a structured questionnaire. The data collection period was May to September, 2017. Data were analysed using descriptive statistics, t-test, ANOVA, Pearson correlation, and multiple linear regression. Results: The mean score for knowledge on blood-borne infections was $15.41{\pm}2.01$ out of 19 and the compliance with blood-borne infection control was $4.08{\pm}0.49$ out of 5. Barriers to the performance of blood-borne infections control were lack of time and personal protective devices. Knowledge on blood-borne infection did not correlate with compliance on blood-borne infection control (r=.13, p=.171). Predictors of compliance on blood-borne infections control were 1) infection control education on injuries caused by injection needles (${\beta}=.23$, p=.010), 2) infection control room (${\beta}=.24$, p=.006) and 3) blood exposure experience over the past week (${\beta}=-.24$, p=.005) and explained 22.2% of the variance (F=10.81, p<.001). Conclusion: Findings suggest that to improve the performance of blood-borne infectious disease management, customized education for nurses on blood-borne infection and systematic support related to the infection control room should be given priority.

Anaplasmosis 은 흡혈성 절지동물인 진드기, 이파리, 모기 등에 의해 매개되는 리케차성 인수공통 전염병이다. 철새는 anaplasmosis의 매개체인 진드기의 숙주이다. 제주도의 다양한 철새 분류군 중에서 지빠귀과 조류의 진드기 감염률이 높다. 특히 마라도는 봄철 남방구에서 북방구로 이동하는 철새의 중간기착점으로 지리적으로 중요한 위치에 있다. 따라서 본 연구에서는 제주도의 대표적 이동철새인 지빠귀과 새들의 Anaplasma spp. 감염여부를 조사하였다. 우리는 마라도에서 34마리의 혈액과 제주야생동물구조센터에서 구조 채취된 6개의 혈액 시료를 대상으로 하였다. 그 결과, 40개체의 지빠귀 중 7개체가 감염이 확인되었으며, 감염률은 17.5%로 나타났다. 7개체 모두 Anaplasma phagocytophilum으로 동정되었다. 이러한 결과는 제주도를 통과하는 대표적인 철새인 지빠귀과 새들이 A. phagocytophilum을 육지로 전파할 수 있음을 시사하며, 다른 이동성 철새들간의 질병전파의 보균자로 작용할 수 있기에 철새, 텃새 및 가축으로의 전파여부를 지속적으로 모니터링할 필요가 있다.

Purpose: Needlestick injuries (NSI) is the most frequent occupational hazard for healthcare personnel (HCP), and immediate report and adequate post-exposure prophylaxis (PEP) is essential in preventing occupational transmission of blood-borne pathogens. Methods: From June 2010 to October 2010, 544 NSI were reported through websites from 21 general hospitals in Korea. Among those, 499 cases of NSI were analyzed to identify the rate of follow-up treatment completion and for seroconversion. Results: 88.2% of the cases were completed with follow-up treatment, 8.8% of the NSI were not completed with follow-up treatment, and 5 cases were unavailable to trace. 4.2% cases of NSI required a hepatitis B vaccination concurrent with hepatitis B immunoglobulin. 41.1% of the cases and 31.1% of the cases needed to be tested for anti HCV and anti HIV, respectively. Prophylaxis medication for HIV was prescribed in 3 cases, and all cases completed required 1 month of medication. There was 1 case (0.2%) of seroconversion to HCV. Conclusion: The PEP completion rate was not satisfactory, and the importance of completion of PEP treatment should be emphasized through education and counseling. Also, a careful risk assessment is needed for HCP who are exposed to HCV or HIV.
